Description

Detailed Description of the Invention

[0001] [Technical field]

[0002] The present disclosure relates to an administration device for administering a medical device to a host. [Background technology]

[0003] Due to the needs of clinical diagnosis or personal health monitoring, for example, for diabetic patients, it is necessary to continuously monitor the glucose concentration of tissue fluid in real time on a daily basis, and to adjust the glucose concentration by methods such as dietary adjustment and drug administration to reduce or mitigate the occurrence of complications caused by abnormal glucose concentration.

[0004] Currently, users typically monitor the glucose concentration in tissue fluid using a glucose sensor that can be inserted under the skin and reacts with glucose in tissue fluid, and an electronic device that is attached to the skin and connected to the glucose sensor. Inserting the glucose sensor under the skin and attaching the electronic device to the skin typically requires the use of an insertion device. Specifically, the insertion device includes a needle that can be inserted into the skin, and after inserting the glucose sensor under the skin through the needle, the needle is separated from the glucose sensor and removed from the skin.

[0005] However, in the above-mentioned conventional technology, the process of inserting and removing the needle from the skin must be driven manually, which makes it difficult to accurately control the force used to drive the needle, the position at which the needle penetrates the skin, the depth at which the needle penetrates under the skin, or the timing at which the needle is removed from the skin, which may affect the user's experience when inserting the glucose sensor, and may result in an inaccurate glucose concentration reading because the glucose sensor is not inserted at the desired position. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in consideration of the above-mentioned state of the art, and aims to provide an administration device that is easy to operate and yet can accurately administer a medical device to a host. [Means for solving the problem]

[0007] To this end, the present invention provides an administration device for a medical device, the administration device including a housing, an auxiliary mechanism, a first drive mechanism, and a second drive mechanism, the housing including a first holding part, a proximal end close to a host during operation, and a distal end far from the host, the auxiliary mechanism including an exercise body releasably held by the first holding part and arranged to be movable relative to the housing upon release, a housing provided on the exercise body and arranged to receive and house the medical device, a second holding part provided on the exercise body, and a second holding part releasably held by the second holding part and arranged to be movable relative to the housing upon release. and a puncture member movably arranged relative to the host, wherein the first drive mechanism is arranged to act on the moving body toward the proximal end and the second drive mechanism is arranged to act on the puncture member toward the distal end, and when the moving body is released, the moving body is driven by the first drive mechanism toward the proximal end so as to place a medical device housed in the housing portion at least partially subcutaneously in the host via the puncture member, and the puncture member is driven by the second drive mechanism toward the distal end so as to move away from the host.

[0008] In the administration device according to this embodiment, the housing includes a proximal end close to the host during operation and a distal end far from the host. The housing, which is configured to receive and house the medical device, and the puncturing member movable relative to the housing are provided on a moving body. The first drive mechanism drives the moving body toward the proximal end to at least partially position the medical device subcutaneously in the host, and the second drive mechanism drives the puncturing member toward the distal end to move the puncturing member away from the host. In this case, the two operational strokes required for administering the medical device—positioning the medical device subcutaneously in the host using the puncturing member and moving the puncturing member away from the host—are arranged to be controlled by the drive mechanism, thereby simplifying the administration of the medical device to the host. Furthermore, the housing includes a proximal end close to the host during operation, which can contribute to limiting the administration location of the medical device. Furthermore, the drive mechanism can provide a relatively accurate driving action, which allows for more accurate control of the puncturing force, puncture depth, and timing of the puncturing member's departure from the host during the administration process, thereby contributing to accurate administration of the medical device to the host.

[0009] In the administration device according to this embodiment, the exercise body may include a first locking portion arranged to releasably interlock with the first holding portion, whereby the exercise body can be releasably held by the first holding portion due to a fit between the first locking portion and the first holding portion.

[0010] In the administration device according to this embodiment, the first holding part may be releasably interlocked with the first locking part via at least one of a snap fit, a hook, a latch, and a pin. In this case, the first holding part and the first locking part are releasably interlocked via at least one of a snap fit, a hook, a latch, and a pin, thereby providing an interlocking means that is easy to release.

[0011] The administration device according to this embodiment may further include a first trigger mechanism arranged to separate the first holding part and the first locking part to release the exercise body, thereby making it possible to easily release the exercise body by the first trigger mechanism.

[0012] In the administration device according to this embodiment, the puncturing member may include a second locking portion arranged to releasably interlock with the second retaining portion, whereby the puncturing member can be releasably retained in the second retaining portion by fitting the second locking portion into the second retaining portion.

[0013] In the administration device according to this embodiment, the second holding part may be releasably interlocked with the second locking part via at least one of a snap fit, a hook, a latch, or a pin. In this case, the second holding part and the second locking part are releasably interlocked via at least one of a snap fit, a hook, a latch, or a pin, thereby providing an interlocking means that is easy to release.

[0014] Furthermore, the administration device according to this embodiment may further include a second trigger mechanism arranged to separate the second holding part and the second locking part to release the puncture member, thereby making it possible to easily release the puncture member by the second trigger mechanism.

[0015] Furthermore, in the administration device according to this embodiment, the housing may include a first housing having the first holding portion and a second housing attachable to the first housing, the second housing having a first limiting mechanism and a second limiting mechanism that communicate with each other, the second limiting mechanism being arranged to limit the attachment position of the medical device, and the auxiliary mechanism being attached to the first limiting mechanism and movable along the first limiting mechanism when the exercise body is released by the first holding portion. In this case, limiting the movement of the exercise body by the first limiting mechanism of the second housing and limiting the attachment position of the medical device by the second limiting mechanism of the second housing is advantageous for more accurate administration of the medical device to the host.

[0016] In addition, in the administration device according to this embodiment, the movement body may have a first bottom portion near the distal end, a second bottom portion near the proximal end, a sidewall connecting the first bottom portion and the second bottom portion, and a hollow portion formed between the first bottom portion, the second bottom portion, and the sidewall, and the storage portion may be provided in the second bottom portion and may be movable along the hollow portion when the puncturing member is released. In this case, by forming a hollow portion with the first bottom portion, the second bottom portion, and the sidewall, and providing the storage portion in the second bottom portion and providing the puncturing member in the hollow portion, it is possible to facilitate movement of the puncturing member relative to the storage portion when released.

[0017] In addition, in the administration device according to this embodiment, the puncturing member may include a sharp object having a groove and a support base for supporting the sharp object, the medical device being disposed entirely or partially in the groove of the sharp object, and the second drive mechanism being disposed to act on the support base. In this case, disposing the medical device entirely or partially in the groove of the sharp object can facilitate subcutaneous placement of at least a portion of the medical device in the host by the puncturing member.

[0018] In the administration device according to this embodiment, the medical device may include a sensor that can be placed under the skin of the host, and an attachment part that is connected to the sensor and can be attached to the body surface of the host. In this case, by connecting the sensor that can be placed under the skin of the host to the attachment part that can be attached to the body surface of the host, analyte information of the interstitial fluid can be easily obtained.

[0019] Furthermore, in the administration device of this embodiment, the first holding portion has a surface facing the distal end, and the first locking portion has a surface facing the proximal end, and when the movement body is held, the surface facing the distal end of the first holding portion is joined to the surface facing the proximal end of the first locking portion, and when the movement body is released, the surface facing the distal end of the first holding portion may be separated from the surface facing the proximal end of the first locking portion.

[0020] In the administration device according to the present embodiment, at least a portion of the first holding part may be L-shaped or hook-shaped, which makes it possible to easily form a structure such as a snap fit to interlock with the first locking part.

[0021] Furthermore, in the administration device according to this embodiment, the first holding part may have an arm extending substantially along the direction of the central axis of the administration device, and a protrusion that protrudes in conjunction with the arm and substantially along a direction perpendicular to the central axis of the administration device. In this case, when the protrusion of the first holding part abuts against the first locking part, the arm is driven to drive the protrusion, thereby allowing the first holding part to easily release the first locking part.

[0022] In the administration device according to the present embodiment, the arm of the first holding part may be elastic in a direction substantially perpendicular to the central axis of the administration device.

[0023] Furthermore, in the administration device according to this embodiment, the arm of the first holding part may approach the central axis of the administration device in the direction from the distal end to the proximal end, and the protrusion of the first holding part may protrude toward the central axis of the administration device. In this case, the first locking part is held inward (closer to the central axis of the administration means) by gathering the entire first holding part inward, and is released by driving the first holding part outward (away from the central axis of the administration means), so that the first locking part can be easily held and released.

[0024] Furthermore, in the administration device according to this embodiment, the arm of the first holding part may be spaced apart from the central axis of the administration device in the direction from the distal end to the proximal end, and the protrusion of the first holding part may protrude apart from the central axis of the administration device. In this case, the first locking part can be held outward (away from the central axis of the administration means) by dispersing the entire first holding part outward, and the first locking part can be released by driving the first holding part inward (closer to the central axis of the administration means), making it easy to hold and release the first locking part.

[0025] In the administration device according to this embodiment, the first locking portion may be spaced apart substantially parallel to the central axis of the administration device in the direction from the proximal end to the distal end, or spaced apart against the central axis of the administration device, which can facilitate fitting and interlocking with the first holding portion that is gathered inward.

[0026] In the administration device according to this embodiment, the first locking portion may approach substantially parallel to or toward the central axis of the administration device in the direction from the proximal end to the distal end, thereby facilitating fitting and interlocking with the outwardly extending first retaining portion.

[0027] In the administration device according to this embodiment, the first trigger mechanism may have a drive unit that extends substantially along the direction of the central axis of the administration device and be arranged to be movable along the direction of the central axis of the administration device. In this case, by driving the drive unit of the first trigger mechanism along the central axis of the administration device, the first holding unit can be driven by a simple operation so as to move away from the first locking unit.

[0028] Furthermore, in the administration device according to this embodiment, when projected in a direction along the central axis of the administration device, the drive portion of the first trigger portion and the first holding portion may at least partially overlap, and when the first trigger portion moves along the direction of the central axis of the administration device, the first holding portion may be driven to move away from the first locking portion. This allows the first holding portion to release the first locking portion with a simple operation.

[0029] In addition, in the administration device according to this embodiment, when projected in a direction along the central axis of the administration device, the drive portion of the first trigger portion and the first locking portion may at least partially overlap, and when the first trigger portion moves along the central axis of the administration device, the first locking portion may be driven to move away from the first holding portion. This allows the first locking portion to be released with a simple operation.

[0030] In addition, in the administration device of this embodiment, the first housing may include a peripheral portion having a hollow cylindrical shape and an end portion provided at one end of the peripheral portion so as to approach the distal end, and the first holding portion may be provided at the end portion.

[0031] Furthermore, in the administration device according to this embodiment, one or more rib-shaped protrusions may be provided on the inner wall of the first housing, one or more rib-shaped grooves may be provided on the outer wall of the second housing, and when the second housing is attached to the first housing, the one or more rib-shaped protrusions may be fitted into the one or more rib-shaped grooves, respectively. In this case, the first housing and the second housing can be easily attached due to the fit between the rib-shaped protrusions and the rib-shaped grooves.

[0032] In the administration device according to this embodiment, the first limiting mechanism and the second limiting mechanism may be hollow cylindrical, and the inner diameter of the first limiting mechanism may be equal to or smaller than the inner diameter of the second limiting mechanism. In this case, by providing the first limiting mechanism and the second limiting mechanism with a hollow cylindrical shape, the auxiliary mechanism can easily move along the first limiting mechanism and the second limiting mechanism.

[0033] In addition, in the administration device according to this embodiment, when the exercise body is released, the exercise body may be movable along the first limiting mechanism, and the storage unit may be movable along the second limiting mechanism. In this case, by moving the exercise body along the first limiting mechanism and moving the storage unit along the second limiting mechanism, the medical device stored in the storage unit can be administered more accurately to a desired position on the host's body surface.

[0034] In the administration device according to this embodiment, the first limiting mechanism may limit the stroke of the movable body in a direction along the central axis of the administration device. In this case, by using the first limiting mechanism to limit the stroke of the movable body in a direction along the central axis of the administration device, the medical device contained in the container can be pushed out a predetermined distance more accurately, and the medical device can be administered more accurately to the host.

[0035] In addition, in the administration device according to this embodiment, when projected in a direction along the central axis of the administration device, the storage unit and a wall of the first limiting mechanism may at least partially overlap, and an end of the movement body close to the distal end may at least partially overlap with the wall of the first limiting mechanism. In this case, by at least partially overlapping the storage unit and the movement body with the wall of the first limiting mechanism, it is possible to effectively limit the stroke of the movement body along the first limiting mechanism while simplifying the structure.

[0036] In the administration device according to this embodiment, the first limiting mechanism may prevent the rotation of the exercise body. In this case, by preventing the rotation of the exercise body, unintended rotation of the puncture member during administration can be prevented.

[0037] In the dispensing device according to this embodiment, the first limiting mechanism may include grooves and / or ridges provided continuously or discontinuously on the inner wall substantially along the direction of the central axis of the dispensing device, in which case engagement of the moving body with the grooves and / or ridges effectively prevents the moving body from unintentionally rotating within the first limiting mechanism.

[0038] In the administration device according to this embodiment, a protrusion may be provided at one end of the movement body near the distal end, protruding away from the central axis of the administration device in a direction substantially perpendicular to the central axis of the administration device. In this case, a snap fit is formed between the protrusion and the wall of the first limiting mechanism, thereby effectively restricting excessive advancement of the movement body toward the proximal end.

[0039] In the dispensing device according to this embodiment, the moving body may include grooves and / or ridges on the outer wall of the sidewall that are substantially aligned with the central axis of the dispensing device, and in this case, the grooves and / or ridges of the moving body may be engaged with the grooves and / or ridges of the first limiting mechanism, thereby effectively preventing the moving body from unintentionally rotating within the first limiting mechanism.

[0040] In the administration device according to this embodiment, the exercise body may have a notch extending substantially along the central axis of the administration device. In this case, by providing the exercise body with a notch extending along the central axis of the administration means, it is possible to facilitate the action of the puncture member provided in the hollow portion of the exercise body.

[0041] In the administration device according to this embodiment, the inner wall of the first limiting mechanism may be provided with a protrusion that can protrude toward the central axis of the administration device through the notch. In this case, when the movement body moves along the first limiting mechanism, the protrusion on the inner wall of the first limiting mechanism can act on the puncture member through the notch in the movement body, thereby providing a trigger mechanism for the puncture member with a simplified structure.

[0042] In addition, in the administration device according to this embodiment, the movement body may be arranged to inhibit rotation of the puncture member, thereby preventing unintended rotation of the puncture member during administration, thereby improving the user experience during administration of the medical device.

[0043] In the dispensing device according to this embodiment, the moving body may include grooves and / or ridges on the inner wall of the side wall that are aligned substantially along the central axis of the dispensing device. In this case, the grooves and / or ridges on the inner wall of the moving body and the grooves and / or ridges on the puncturing member fit together to effectively prevent the puncturing member from rotating unintentionally during dispensing.

[0044] In addition, in the administration device according to this embodiment, the sharp object may be integrally formed with the support base.

[0045] In addition, in the administration device according to this embodiment, the sharp object may be arranged to be removably attached to the support base, which makes it easier to sterilize the sharp object separately.

[0046] In the administration device according to this embodiment, the sharp object may have a needle-shaped portion and a cap portion fixedly connected to the needle-shaped portion, the support base may have a plurality of finger portions that approach each other, and the cap portion may be releasably held by the plurality of finger portions. In this case, the cap portion of the sharp object fits into the plurality of finger portions of the support base, making it possible to easily attach and detach the sharp object to and from the support base.

[0047] Furthermore, in the administration device according to this embodiment, the puncturing member may include a second locking portion disposed on the support base and arranged to releasably interlock with the second holding portion, the second locking portion including an arm extending substantially along the direction of the central axis of the administration device and a protrusion interlocked with the arm and protruding away from the central axis of the administration device substantially along a direction perpendicular to the central axis of the administration device. In this case, when the puncturing member is disposed in the hollow portion of the exercise body, the second locking portion may abut against a notch in the exercise body, thereby enabling the puncturing member to be held in a simplified structure.

[0048] In addition, in the administration device according to this embodiment, the arm of the second locking portion may be elastic in a direction substantially perpendicular to the central axis of the administration device.

[0049] In the administration device according to this embodiment, the main body may have a notch extending substantially along the central axis of the administration device, and the protrusion of the second locking part may pass through the notch when the puncture member is held. In this case, the protrusion of the first locking part may abut against the notch of the main body, thereby simplifying the structure of the first locking part.

[0050] In addition, in the administration device according to this embodiment, when the puncture member is released, the arm of the second locking part may be pressed toward the central axis of the administration device, thereby allowing the second locking part to be released with a simple operation.

[0051] In the administration device according to this embodiment, the support base may include grooves and / or ridges on the outer wall substantially aligned with the central axis of the administration device, whereby the grooves and / or ridges on the support base fit into the grooves and / or ridges on the inner wall of the side wall of the movement body, thereby effectively preventing unintended rotation of the puncture member.

[0052] In addition, in the administration device according to this embodiment, a support base for the puncturing member may be provided within the hollow portion, the storage portion may be provided in the second bottom portion, the second bottom portion may have a through-hole, and the sharp object may pass through the through-hole in the second bottom portion. In this case, by providing the sharp object to pass through the through-hole in the second bottom portion, the sharp object can be joined to the medical device stored in the storage portion, thereby making it easier to at least partially position the medical device subcutaneously in the host by the puncturing member.

[0053] Furthermore, in the administration device according to this embodiment, the distance between the support base and the first bottom portion when the puncturing member is held may be equal to or greater than the length by which the sharp object protrudes from the storage portion. In this case, by making the distance between the support base and the first bottom portion equal to or greater than the length by which the sharp object protrudes from the storage portion, a movement space for the puncturing member to move away from the host can be provided, thereby reducing unintended damage to the host by the puncturing member.

[0054] In the administration device according to this embodiment, when the puncture member is held, the second holding part may be releasably interlocked with the second locking part via at least one of a snap fit, a hook, a latch, or a pin. In this case, by releasably interlocking the second holding part and the second locking part with a simple configuration, the second locking part can be released with a simple operation.

[0055] In the administration device according to this embodiment, the second drive mechanism may be provided between the support base and the second bottom portion, thereby contributing to applying an action to the puncturing member so as to move the puncturing member away from the storage portion.

[0056] In the administration device according to this embodiment, the second drive mechanism may be a spring, which allows a drive mechanism to be provided for the pricking member with a simple structural design.

[0057] In the dispensing device according to this embodiment, the first driving mechanism may be a spring, which allows the exercise body to be provided with a driving mechanism through a simple structural design.

[0058] In the administration device according to the present embodiment, the sensor may be arranged to react with an analyte in the bodily fluid to generate analyte information, whereby the sensor reacts with the analyte in the bodily fluid to facilitate obtaining the analyte information in the bodily fluid.

[0059] In addition, in the administration device of this embodiment, the analyte may be one or more of acetylcholine, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase, creatine, creatinine, DNA, fructosamine, glucose, glutamine, growth hormone, hormone, ketone bodies, lactate, oxygen, peroxide, prostate-specific antigen, prothrombin, RNA, thyroid-stimulating hormone, or troponin.

[0060] In the administration device according to this embodiment, the sensor may include a fitting portion that can be placed under the skin of the host and a connecting portion that connects the fitting portion and the attachment portion. In this case, by placing the fitting portion under the skin of the host and connecting the fitting portion and the attachment portion with the connecting portion, it is possible to easily transmit the acquired analyte information to an external device.

[0061] In the administration device according to this embodiment, the sensor may be removably attached to the adhesive part, in which case the sensor and the adhesive part can be sealed separately before the medical device is housed in the housing part, making it easier to sterilize the sensor and the adhesive part separately.

[0062] In addition, in the administration device according to this embodiment, the attachment part may be arranged to provide power to the sensor and receive information generated by the sensor, thereby contributing to the sensor's continuous subcutaneous monitoring of the host.

[0063] In the administration device according to this embodiment, the attachment part may have a hole penetrating from the top surface to the bottom surface, and the axis of the sensor may pass through the hole when the sensor is attached to the attachment part. In this case, inserting a puncture member subcutaneously through the hole can contribute to positioning the sensor subcutaneously.

[0064] In the administration device according to this embodiment, the attachment part may be arranged so as to be adhered to the body surface of the host.

[0065] In the administration device according to the present embodiment, the attachment part may have an initial state in which it is arranged in an open circuit and an operating state in which it is arranged in a closed circuit. In this case, by having the attachment part arranged in the open circuit in the initial state, it is possible to save power consumption until the attachment part is arranged in the operating state.

[0066] In the administration device according to this embodiment, the attachment part may be arranged to be able to communicate with an external device via wireless or wired communication, so that the acquired analyte information can be read in real time or at a fixed time.

[0067] In the administration device according to the present embodiment, the attachment part may be arranged to be excited from the initial state to the operating state by a magnetic or optical action. In this case, exciting the attachment part from the initial state to the operating state by a non-contact member such as a magnetic or optical action can contribute to miniaturization of the attachment part.

[0122] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the same components are designated by the same reference numerals, and redundant explanations will be omitted. Furthermore, the drawings are schematic, and the dimensional ratios and shapes of the components may differ from those of the actual components. It should be noted that in this disclosure, the terms "comprise" and "have" and any variations thereof, for example, a process, method, system, product or device comprising or having a series of steps or units, are not necessarily limited to those steps or units expressly recited, but may include other steps or units not expressly recited or inherent to the process, method, product or device. An embodiment of the present disclosure relates to an administration device for a medical device, for example, by attaching the medical device to the body surface of a host or by placing all or a part of the medical device subcutaneously, etc., in order to administer the medical device to a host. The administration device according to the embodiment can contribute to administering the medical device to a desired location.

[0123] The administration device according to this embodiment may be called, for example, an assist device, a transport device, a transplant device, an attachment device, an auxiliary device, etc. Note that each name indicates a device for administering the medical device according to this embodiment to a host, and should not be interpreted in a limiting sense.

[0124] 1 is a diagram showing an outline of administration using a medical device 800 and an administration device 1000 according to this embodiment. In this embodiment, the medical device 800 is administered to a host via the administration device 1000 and administered to a desired location, and the host can acquire biological information from the medical device 800 administered to the host.

[0125] The present disclosure also provides a monitoring system that can include a medical device 800 according to the present embodiment that can acquire biometric information of a host, and a reading device 900 (see FIG. 1 ) that is communicatively connected to the medical device 800. The medical device 800 administered to the host can transmit the acquired biometric information to the reading device 900, for example, wirelessly, thereby making it easy for the host to read and monitor its own biometric information.

[0126] The present disclosure also provides a cassette device 2000 (see FIG. 1 ), which is used to house all or part of the medical device 800 according to the present embodiments. In some examples, the medical device 800 according to the present embodiments may be housed all or partly within the cassette device 2000 before being administered to a host.

[0127] The present disclosure also provides an instrument set that can include a medical device 800 according to the present embodiment that can acquire physiological information of a host, an administration device 1000 that can administer the medical device 800 according to the present embodiment to a host, and a cassette device 2000 that can store the medical device 800 according to the present embodiment. The medical device 800 may be stored in whole or in part within the cassette device 2000 before being administered to the host, and when the medical device 800 is needed, the medical device 800 may be removed by the administration device 1000 and administered to the host.

[0128] In some examples, the medical device 800 may be a sensing device. In some examples, the medical device 800 may generate information about a specific analyte in the bodily fluid based on the bodily fluid, such as an analyte sensor device that reacts with an analyte in the bodily fluid to generate analyte information. In this case, the sensor reacts with the analyte in the bodily fluid, thereby easily obtaining the analyte information in the bodily fluid.

[0129] In this embodiment, the analyte of interest to the analyte sensor device may be one or more of glucose, acetylcholine, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine, creatinine, DNA, fructosamine, glutamine, growth hormone, hormones, ketone bodies, lactate, oxygen, peroxide, prostate specific antigen, prothrombin, RNA, thyroid stimulating hormone, or troponin.

[0130] The medical device 800 according to this embodiment will be described below using glucose as an example of an analyte. Note that for other analytes, those skilled in the art can analyze other analytes by slightly modifying the medical device 800 adopted for glucose.

[0131] Fig. 2 is a schematic diagram showing a first viewpoint of a medical device 800 according to one example of this embodiment. Fig. 3 is a schematic diagram showing a second viewpoint of a medical device 800 according to this example of this embodiment.

[0132] In some examples, the medical device 800 may include a sensor 820, a connection portion 840, and an attachment portion 860 (see FIG. 2 or FIG. 3). The sensor 820 may be removably attached to the attachment portion 860. The sensor 820 may be connected to the attachment portion 860 by the connection portion 840. In other examples, the medical device 800 may not include the connection portion 840, in which case the sensor 820 may be directly connected to the attachment portion 860.

[0133] In some examples, the sensor 820 may be partially or completely placed subcutaneously in the host. In some examples, after being placed subcutaneously, the sensor 820 may react with glucose in subcutaneous tissue fluid to generate glucose information for the host. The affixing unit 860 may be attached to the body surface of the host. In some examples, the affixing unit 860 may receive the glucose information generated by the sensor 820. In some examples, the affixing unit 860 may provide the sensor 820 with the power necessary to acquire biological information, thereby allowing the sensor 820 to continuously monitor the host subcutaneously.

[0134] In some examples, the sensor 820 may include a fitting portion (not shown) and a connecting portion (not shown). The fitting portion may be placed subcutaneously in the host and connected to the attachment portion 860 via the connecting portion. In this case, by placing the fitting portion subcutaneously in the host and connecting the fitting portion and the attachment portion 860 via the connecting portion, it is possible to easily transmit the acquired analyte information to an external device. In some examples, the connecting portion may be connected to the attachment portion 860 via the connecting portion 840.

[0135] In some examples, the inset portion of sensor 820 may have an elongated shape. In some examples, the inset portion may be rigid, which may facilitate subcutaneous placement in a host. In another example, the inset portion may be flexible, which may reduce the host's sense of a foreign body. In some examples, the length of the inset portion may be 1 mm-10 mm, for example, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. After implantation into a host, the inset portion may reach a depth that reaches the dermis layer and is positioned between skin tissues, allowing sensor 820 to collect glucose information in interstitial fluid.

[0136] In some examples, the fitting portion can include a working electrode (not shown) and a counter electrode (not shown). In this embodiment, the working electrode can be provided with a sensing layer containing glucolase, and the glucolase in the working electrode in the subcutaneously placed sensor 820 can undergo an oxidation-reduction reaction with glucose in the interstitial fluid or blood to form a circuit with the counter electrode, thereby generating a current signal. The current signal can be analyzed and processed to obtain glucose concentration information. In some examples, the current signal generated by the sensor 820 can be transmitted to the adhesive portion 860.

[0137] In some examples, the fitting portion may further include a reference electrode (not shown). In some examples, the reference electrode may form a known, constant potential difference with the interstitial fluid or blood. In this case, the potential difference between the working electrode and the interstitial fluid or blood can be measured by the potential difference between the reference electrode and the working electrode. This allows the voltage generated at the working electrode to be obtained more accurately. This allows the electronic device 880 (described below) of the attachment portion 860 to automatically adjust and maintain the stabilization of the voltage at the working electrode based on a preset voltage value, allowing the measured current signal to more accurately reflect information about the glucose concentration in the interstitial fluid or blood. In some examples, the number of reference electrodes may be one or more, for example, two.

[0138] 4 is a schematic diagram showing the connection portion 840 of the medical device 800 according to this embodiment. In some examples, as described above, the sensor 820 may be attached to the attachment portion 860 via the connection portion 840. In some examples, the sensor 820 may be structurally connected to the attachment portion 860 via the connection portion 840. In some examples, the sensor 820 may be electrically connected to the attachment portion 860 via the connection portion 840.

[0139] In some examples, the connection portion 840 may have a sensor connection hole 842 (see FIG. 4). In some examples, when the sensor 820 is connected to the connection portion 840, the axis of the sensor 820 may pass through the sensor connection hole 842 (see FIG. 2 or 3). In this case, the sensor connection hole 842 allows the puncture member 260 (described below) to be easily coupled to the sensor 820, and the puncture member 260 makes it easy to position the sensor 820 at least partially subcutaneously in the host.

[0140] In some examples, the connection portion 840 may further include electrical contacts 844 (see FIG. 4 ). The electrical contacts 844 may be electrically connected to the working electrode, the counter electrode, and the reference electrode of the sensor 820. This may facilitate transmission of glucose information acquired by the sensor 820 to an external device. The number of electrical contacts 844 may be two, three, or four. In the example shown in FIG. 4 , the electrical contacts 844 may include 844a, 844b, and 844c. However, this example embodiment is not limited thereto, and the number of electrical contacts 844 may be the same as the number of electrodes of the sensor 820.

[0141] In some examples, the connecting portion 840 may further include a structure that allows it to be fastened to the affixing portion 860. In some examples, the connecting portion 840 may further include an engaging portion 846 (see FIG. 4) provided around the periphery. The engaging portion 846 of the connecting portion 840 can engage with an engaging groove 868 (described below) of the affixing portion 860 to fasten and attach the connecting portion 840 and the affixing portion 860. In some examples, the engaging portion 846 may be a protrusion that protrudes outward along the periphery of the connecting portion 840 (see FIG. 4). In some examples, the number of engaging portions 846 may be one or more, for example, one, two, three, or four. In some examples, the multiple engaging portions 846 may be uniformly distributed around the connecting portion 840. In the embodiment shown in FIG. 4, the engaging portions 846 may include 846a, 846b, 846c, and 846d.

[0142] In some examples, the connecting portion 840 may be substantially cylindrical, for example, rectangular. However, this embodiment is not limited thereto, and in other examples, the connecting portion 840 may be substantially triangular, hexagonal, cylindrical, or hemispherical. Furthermore, the receiving portion 866 of the attachment portion 860 may be formed in a shape that matches the connecting portion 840 so as to be suitable for receiving the connecting portion 840.

[0143] 5 is a schematic diagram showing the attachment portion 860 of the medical device 800 according to this embodiment. In some examples, the attachment portion 860 may include an attachment housing 862, a connection portion joining hole 864, and a receiving portion 866 (see FIG. 5). The receiving portion 866 may be formed as a recess that matches the contour of the connection portion 840, or the connection portion 840 may be embedded in the receiving portion 866 (see FIG. 3).

[0144] In some examples, the attachment part 860 may further include a hole 864 (see FIG. 5) penetrating from the upper surface to the lower surface, and when the sensor 820 is attached to the attachment part 860, the axis of the sensor 820 can pass through the hole (see FIGS. 2 and 3). In this case, the sensor 820 can be easily placed subcutaneously by inserting a puncturing member 260 (described below) subcutaneously through the hole 864.

[0145] In some examples, when the connecting portion 840 is fitted into the receiving portion 866, the connecting portion joining hole 864 of the affixing portion 860 and the sensor joining hole 842 of the connecting portion 840 can be in communication with each other. That is, when the sensor 820 is connected to the connecting portion 840 and the connecting portion 840 is embedded in the affixing portion 860, the central axis of the fitting portion of the sensor 820 may pass through the sensor joining hole 842 and the connecting portion joining hole 864 (see FIGS. 2 and 3 ).

[0146] In some examples, the sensor 820 may be arranged to be removably attached to the attachment portion 860. In this case, the sensor 820 and the attachment portion 860 may be sealed separately before the medical device 800 is housed in the housing portion 250, which may facilitate separate sterilization of the sensor 820 and the attachment portion 860 using different methods.

[0147] In some examples, the affixing portion 860 may include a structure that can fasten and attach the connecting portion 840. In some examples, the affixing portion 860 may further include an engagement groove 868 (see FIG. 5 ). The engagement groove 868 may be provided in the receiving portion 866. In some examples, the engagement groove 868 may be a recess formed in a side wall of the receiving portion 866 along a direction substantially perpendicular to the central axis of the affixing housing 862. The number of engagement grooves 868 may be the same as the number of engagement portions 846 of the connecting portion 840. The engagement portions 846 are engageable with the engagement grooves 868 when the connecting portion 840 is fitted into the affixing portion 860. In the embodiment shown in FIG. 5 , the engagement grooves 868 may include engagement grooves 868a, 868b, 868c, and 868d.

[0148] In some examples, the bottom wall of the receiving portion 866 is further provided with electrical contacts (not shown) that correspond to the electrical contacts 844a, 844b, and 844c of the connecting portion 840, respectively, and that communicate with an electronic device 880 (described below). As a result, the sensor 820 is electrically connected to the electronic device 880 via the electrical contacts 844 of the connecting portion 840 and the electrical contacts of the attachment portion 860.

[0149] In some examples, the attachment part 860 is arranged so as to be able to adhere to the body surface of the host. In some examples, the attachment part 860 may further include an adhesive sheet 870 (see FIG. 2 or 3) having adhesive properties provided on the attachment housing 862. The attachment part 860 may be attached and fixed to the body surface of the host by the adhesive sheet 870. In some examples, the adhesive surface of the adhesive sheet 870 may be approximately equal to the bottom surface of the attachment housing 862 that is closer to the host. In other examples, the adhesive surface of the adhesive sheet 870 may be slightly larger than the bottom surface of the attachment housing 862 that is closer to the host.

[0150] In some examples, the affixing unit 860 may further include an electronic device 880 (described below) provided inside the affixing housing 862. The electronic device 880 may receive the glucose information generated by the sensor 820. In some examples, the electronic device 880 may further process the glucose information. In other examples, the electronic device 880 may transmit the received glucose information to an external device, for example, a reading device 900 (described below). The electronic device 880 may also supply power to the sensor 820.

[0151] FIG. 6A is a block diagram illustrating the electronics 880 of the medical device 800 according to this example embodiment.

[0152] In some examples, electronic device 880 may include a power supply module 882, a switch module 884, and a processing module 886 (see FIG. 6A ). Power supply module 882 can provide power to sensor 820 and / or processing module 886, switch module 884 can control the on / off of power supply module 882, sensor 820, and / or processing module 886, and processing module 886 can process signals (e.g., glucose information) generated by sensor 820.

[0153] In some examples, the affixing unit 860 has an initial mode in which it is disposed in an open circuit state and an operating mode in which it is disposed in a closed circuit state. In this case, by disposing the affixing unit 860 in an open circuit state in the initial mode, it is possible to save power consumption until the affixing unit 860 is in an operating state. In some examples, when the affixing unit 860 is disposed in the initial mode, the switch module 884 may be in an off state, and when the affixing unit 860 is disposed in the operating mode, the switch module 884 may be in an on state. In other words, the switch module 884 can switch the affixing unit 860 from the initial mode to the operating mode. In this case, by controlling the switch module 884 to switch the affixing unit 860 from the initial mode to the operating mode, it is possible to effectively reduce power consumption before operation.

[0154] In some examples, the electronic device 880 may further include a storage module 888 (see FIG. 6A). The storage module 888 may store the signal generated by the sensor 820. In some examples, the electronic device 880 may further include a communication module 890 (see FIG. 6A). The communication module 890 may communicate with an external device (e.g., a smart terminal device). In some examples, the communication module 890 may be a Bluetooth module, an NFC module, a WIFI module, etc. In some examples, the smart terminal device may be a smartphone, a smart watch, a tablet computer, a computer, etc.

[0155] In some examples, the electronic device 880 can transmit the glucose information generated by the sensor 820 to the external device immediately after receiving the information. This makes it easy for the external device to process or display the glucose information immediately. In other examples, the electronic device 880 can first store the glucose information generated by the sensor 820 in the storage module 888 after receiving the information, and then transmit the information to the external device periodically. This can reduce power consumption due to immediate transmission.

[0156] In some examples, the attachment unit 860 may be arranged to be excited from the initial mode to the operating mode by magnetic or optical action. In this case, exciting the attachment unit 860 from the initial mode to the operating mode by a non-contact member such as magnetic or optical action can contribute to miniaturization of the attachment unit 860.

[0157] In some examples, the switch module 884 may be configured as an optically controlled switch. For example, in an initial mode, the switch module 884 may be in an off state, and when the switch module 884 receives light, the switch module 884 is activated from the off state to an on state, providing power to the processing module 886 by connecting the power supply module 882 and the processing module 886.

[0158] In another example, the switch module 884 may be arranged as a magnetically controlled switch. For example, in the initial mode, the switch module 884 may be in an OFF state, and when the magnetic influence received by the switch module 884 changes, the switch module 884 is switched from the OFF state to the ON state, thereby exciting the attachment unit 860 from the initial mode to the operating mode. FIG. 6B is a circuit schematic diagram showing the electronic device 880 of the medical device 800 according to this embodiment. The switch module 884 arranged to be controlled by magnetism according to this embodiment will be described in detail below with reference to FIG. 6B.

[0159] In some examples, when the switch module 884 is close to the magnetic member, the switch module 884 may be in an off state, and when the switch module 884 is away from the magnetic member, the switch module 884 may be energized to an on state. In other examples, when the switch module 884 is away from the magnetic member, the switch module 884 may be in an off state, and when the switch module 884 is close to the magnetic member, the switch module 884 may be energized to an on state.

[0160] In some examples, the switch module 884 may include a Hall sensor 884a and a switch chip 884b (see FIG. 6B ). In some examples, in an initial mode, the switch chip 884b may be in an off state, and when the Hall sensor 884a detects a change in magnetic action, an excitation signal may be generated to energize the switch chip 884b from the off state to an on state, thereby connecting the power supply module 882 and the processing module 886. In some examples, after the processing module 886 and the power supply module 882 are connected, the processing module 886 may generate and send an excitation signal to the switch chip 884b to keep the switch chip 884b in a closed state.

[0161] In some examples, the administration device 1000 (described below) may include a magnet 184. When the medical device 800 is not being administered to a host, the electronic device 880 of the medical device 800 may be close to the magnet 184 such that the switch module 884 of the electronic device 880 is in an off state. When the medical device 800 is administered to a host, the electronic device 880 of the medical device 800 may be moved away from the magnet 184 such that the switch module 884 of the electronic device 880 may be energized to an on state.

[0162] Specifically, when the medical device 800 is not being administered to a host, the electronic device 880 may be in an initial mode, i.e., the switch chip 884b of the switch module 884 may be in an off state, and the Hall sensor 884a may be close to the magnet 184 of the administration device 1000. When the medical device 800 is administered to a host, the Hall sensor 884a moves from the magnet 184 close to the administration device 1000 to the magnet 184 away from the magnet 184, causing the magnetic effect sensed by the Hall sensor 884a to change and generate an excitation signal. The switch chip 884b is excited to an on state by the excitation signal generated by the Hall sensor 884a, thereby connecting the power supply module 882 and the processing module 886. In some examples, after the power supply module 882 and the processing module 886 are connected, the processing module 886 may generate an excitation signal and send it to the switch chip 884b to keep the switch chip 884b in an on state.

[0163] Also, in some examples, the power supply module 882 of the electronic device 880 may be arranged to provide power to the sensor 820. In some examples, when the electronic device 880 is in an initial mode, the power supply module 882 and the sensor 820 may be disconnected, and when the electronic device 880 is activated to an operational mode (i.e., when the switch module 884 is in an on state), the power supply module 882 may be in communication with the sensor 820 to provide power to the sensor 820.

[0164] In some examples, as described above, the affixing unit 860 may be configured to be able to communicate with an external device via wireless or wired communication. In this case, by configuring the affixing unit 860 to be able to communicate with the external device, the analyte information acquired by the sensor 820 can be read in real time or at a scheduled time. In some examples, the external device may be the reading device 900.

[0165] In some examples, as described above, the medical instrument 800 is communicatively connected to the reading device 900. In some examples, the reading device 900 may be a display with a communication function. In some examples, the communication function of the reading device 900 may be realized by a wireless communication method or a wired communication method. The wireless communication method may be Bluetooth (registered trademark), NFC, WIFI, etc. The wired communication method may be USB, optical fiber, etc.

[0166] In another example, the reading device 900 may be a smart terminal installed with an application program that matches the medical instrument 800. The smart terminal may be a laptop computer, a tablet computer, a smartphone, or the like.

[0167] As described above, the medical device 800 according to this embodiment may be administered to a host by the administration device 1000. The administration device 1000 according to this embodiment will be described in detail below with reference to the drawings.

[0168] Fig. 7A is a schematic diagram of the overall appearance of the administration device 1000 according to this embodiment, showing a first viewpoint thereof, Fig. 7B is a schematic diagram of the overall appearance of the administration device 1000 according to this embodiment, showing a second viewpoint thereof, and Fig. 7C is an exploded schematic diagram of the administration device 1000 according to this embodiment. In Figs. 7A, 7B, and 7C, line CA schematically indicates the central axis of the administration device 1000.

[0169] In this embodiment, the administration device 1000 may include a housing 10 capable of providing a movement space, and an assist mechanism 20 configured to be movable within the movement space of the housing 10 (see FIGS. 7A, 7B, and 7C). The housing 10 may have a proximal end that approaches the host during operation and a distal end that moves away from the host. The assist mechanism 20 is releasably held by the housing 10 and can house the medical device 800. The assist mechanism 20 is arranged to be movable relative to the housing 10 during release, and can be driven toward the host to administer the medical device 800 to the host. In this specification, the "proximal end" can be understood as an end that is closer to the host during operation, and the "distal end" can be understood as an end that is farther from the host during operation.

[0170] In some examples, the housing 10 may have a movement space, and the assist mechanism 20 may be releasably held by the housing 10. In some examples, when the assist mechanism 20 is released, it can move within the movement space of the housing 10. Also, in some examples, the housing 10 may limit the position where the medical device 800 is attached to the host's body surface.

[0171] In some examples, the housing 10 may include a first housing 100 and a second housing 140. When the first housing 100 and the second housing 140 are attached and coupled together, a movement space is formed. The first housing 100 can releasably hold the assist mechanism 20. The second housing 140 can limit the attachment position of the medical device 800 on the host's body surface and limit the movement path of the assist mechanism 20. After being released by the first housing 100, the assist mechanism 20 can move relative to the second housing 140 along the movement path defined by the second housing 140, and administer the medical device 800 to the attachment position defined by the second housing 140. In this embodiment, the axis of the first housing 100 and the axis of the second housing 140 may be approximately parallel to the central axis CA of the administration device 1000.

[0172] In some examples, the assist mechanism 20 may include a movement body 200, a housing 250, and a puncturing member 260 (see FIG. 7C ). The movement body 200 is releasably held by the first housing 100, and may be configured to be movable along a path defined by the second housing 140 upon release. The housing 250 may be provided on the movement body 200 and positioned to receive and house the medical device 800, and the housing 250 may be driven toward the attachment position defined by the second housing 140. The puncturing member 260 may be provided on the movement body 200 so as to pass through the housing 250. After being released, the movement body 200 can move toward the proximal end of the housing 10, and the housing 250 and the puncturing member 260 also move toward the proximal end of the housing 10, thereby administering the medical device 800 housed in the housing 250 to the host. In some instances, the piercing member 260 can be penetrated subcutaneously of the host to position the medical device 800 at least partially subcutaneously of the host.

[0173] In some examples, the administration device 1000 may further include a first drive mechanism 30 (see FIG. 7C ). The first drive mechanism 30 may be arranged to act on the movement body 200 toward the proximal end. When the movement body 200 is released, the movement body 200 is driven toward the proximal end by the first drive mechanism 30 to push the medical device 800 housed in the housing 250 toward the host, for example, to an application position defined by the second housing 140. The puncture member 260 may also position the medical device 800 at least partially subcutaneously in the host.

[0174] In another example, the administration device 1000 may not include the first drive mechanism 30. In this case, when the movement body 200 is released, the movement body 200 may be manually driven to move toward the proximal end.

[0175] Also, in some examples, the puncturing member 260 may be releasably provided on the movement body 200, and when released, the puncturing member 260 may be arranged to be movable relative to the housing 250. For example, when released, the puncturing member 260 may move relative to the housing 250 in a direction away from the host.

[0176] In some examples, the administration device 1000 may further include a second drive mechanism 40 (see FIG. 7C). The second drive mechanism 40 may be arranged to act on the puncture member 260 toward the distal end. When the puncture member 260 is released, the puncture member 260 is driven toward the distal end by the second drive mechanism 40, and the puncture member 260 moves away from the host.

[0177] In another example, the administration device 1000 may not include the second drive mechanism 40. In this case, the puncture member 260 may be manually driven to move away from the host. For example, in some examples, the puncture member 260 may be integrally connected to the movement body 200, and the puncture member 260 is moved away from the host by manually moving the movement body 200 in a direction away from the host.

[0178] In some examples, as described above, the housing 10 may include a first housing 100 (see FIG. 7A, 7B, or 7C). In some examples, the first housing 100 may include a peripheral portion 110 and an end portion 120 (see FIG. 7C).

[0179] Figure 8A is a schematic perspective view showing the peripheral portion 110 of the first housing 100 according to this embodiment, and Figure 8B is a schematic perspective view showing the end portion 120 of the first housing 100 according to this embodiment. In some examples, the peripheral portion 110 may be formed as a hollow cylindrical housing that runs vertically along a central axis CA of the administration device 1000 (see Figure 8A), and the end portion 120 may be provided on the peripheral portion 110 so as to approach the distal end of the housing 10. In some examples, the central axis CA may pass through the geometric center of the end portion 120.

[0180] In some examples, one or more rib-like protrusions may be provided on the inner wall of the first housing 100, and one or more rib-like grooves may be provided on the outer wall of the second housing 140. In some examples, when the second housing 140 is attached to the first housing 100, one or more rib-like protrusions of the first housing 100 may be fitted into one or more rib-like grooves of the second housing 140, respectively. In this case, the fit between the rib-like protrusions and the rib-like grooves makes it possible to easily attach the first housing 100 and the second housing 140.

[0181] In some examples, the inner wall of the peripheral portion 110 may be provided with peripheral ribs 112 (see FIG. 8A ) extending substantially along the direction of the central axis CA. In some examples, the number of peripheral ribs 112 may be multiple, for example, two, three, or four. In the embodiment shown in FIG. 8A , the number of peripheral ribs 112 is four, and the peripheral ribs 112 may include peripheral ribs 112a, 112b, 112c, and 112d. In some examples, the peripheral ribs 112 function as reinforcing ribs to effectively improve the deformation resistance of the peripheral portion 110. In some examples, the peripheral ribs 112 also function as guide ribs to facilitate attachment of the first housing 100 and the second housing 140 (described below).

[0182] In some examples, the inner wall of the peripheral portion 110 may further include connecting posts 114 (see FIG. 8A ) substantially parallel to the central axis CA. In some examples, the number of connecting posts 114 may be multiple, for example, two, three, or four. In the embodiment shown in FIG. 8A , the number of connecting posts 114 is three, and the connecting posts 114 may include connecting posts 114a, 114b, and 114c. In some examples, one end of the connecting posts 114 near the proximal end of the administration device 1000 may be a hot-type post end, i.e., it can be molten by heating and subsequently solidified by cooling. In this case, the connecting posts 114 may fit into holes provided in the second housing 140 and be attached and coupled to the second housing 140 (described below).

[0183] In some examples, end portion 120 may include a generally cylindrical end portion body 121 (see FIG. 8B).

[0184] In some examples, the first housing 100 may include a first holding portion 130. In some examples, the first holding portion 130 may be arranged to releasably hold the assist mechanism 20. In some examples, the first holding portion 130 may be provided on the end portion 120 (see FIG. 8B ). In some examples, the first holding portion 130 may extend along the central axis CA from the end body 121 toward the proximal end of the administration device 1000. In this case, when the assist mechanism 20 is held on the end portion 120, the assist mechanism 20 may be located within the hollow portion of the peripheral portion 110, and when the assist mechanism 20 is released, the assist mechanism 20 may move approximately along the axial direction of the peripheral portion 110. In other words, when the assist mechanism 20 is released, the assist mechanism 20 is movable approximately along the central axis CA.

[0185] In some examples, the first holding portion 130 can be releasably interlocked with the held member (for example, the first locking portion 236 of the moving body 200 described below) by at least one structure of a snap fit, a hook, a latch, or a pin. In this case, the first holding portion 130 and the first locking portion 236 can be releasably interlocked by at least one structure of a snap fit, a hook, a latch, and a pin, thereby providing an interlocking means that is easy to release.

[0186] In some examples, the number of first holding portions 130 may be one or more, for example, 1, 2, 3, or 4. In the embodiment shown in FIG. 8B, the number of first holding portions 130 may be two, and the first holding portions 130 may include first holding portions 130a and 130b. The first holding portions 130a and 130b may be disposed at equal intervals on opposite sides of the central axis CA (see FIG. 8B).

[0187] In some examples, the first holding portion 130 may have a surface facing the distal end, and the first locking portion 236 may have a surface facing the proximal end, and when the moving body 200 is held, the surface facing the distal end of the first holding portion 130 and the surface facing the proximal end of the first locking portion 236 may abut each other. In some examples, when the moving body 200 is released, the surface facing the distal end of the first holding portion 130 and the surface facing the proximal end of the first locking portion 236 may move away from each other.

[0188] In some examples, at least a portion of the first retaining portion 130 may be L-shaped or hook-shaped, which allows for easy formation of a structure such as a snap fit to interlock with the first locking portion 236.

[0189] In some examples, the first holding portion 130 may include an arm 132 extending substantially along the direction of the central axis CA, and a protrusion 134 linked to the arm 132 and protruding toward the central axis CA along a direction substantially perpendicular to the central axis CA (see FIG. 8B). In some examples, the arm 132 of the first holding portion 130 may extend outward from the end body 121. In this case, when the protrusion 134 of the first holding portion 130 abuts against the first locking portion 236, the arm 132 can be driven to drive the protrusion 134, thereby allowing the first holding portion 130 to easily release the first locking portion 236.

[0190] In some examples, a groove (not shown) may be provided in the arm 132 of the first holding unit 130, extending substantially along the central axis CA. In some examples, the groove may face the central axis CA. In this case, the drive unit 504 of the first trigger mechanism 50, which will be described later, can move along the groove to drive the arm 132 of the first holding unit 130.

[0191] In some examples, the arm 132 of the first holding portion 130 may be elastic. In some examples, the arm 132 of the first holding portion 130 may be elastic in a direction approximately perpendicular to the central axis CA. In some examples, the arm 132 of the first holding portion 130 may tend to contract toward the central axis CA in a direction from the distal end to the proximal end. That is, in a natural state (i.e., when not subjected to an external force), when comparing one end of the arm 132 closer to the proximal end with one end of the arm 132 closer to the distal end, the one end of the arm 132 closer to the proximal end is closer to the central axis CA. In other examples, the arm 132 may be approximately parallel to the central axis CA. In some examples, applying an action to the arm 132 in a direction approximately perpendicular to the central axis CA may cause the arm 132 to pivot. For example, when an action is applied to arm 132 to move away from central axis CA along a direction substantially perpendicular to central axis CA, arm 132 may pivot so that one end closer to the proximal end of arm 132 moves in a direction away from central axis CA. This allows the held member to be released with a simple operation.

[0192] In some examples, the arms 132 of the first holding portion 130 can approach the central axis CA along the direction from the distal end to the proximal end, and the protrusions 134 of the first holding portion 130 can protrude toward the central axis CA. In this case, the first locking portion 236 can be held by gathering the entire first holding portion 130 inward (toward the central axis CA), and the first locking portion 236 can be released by driving the first holding portion 130 outward (away from the central axis CA), thereby making it easy to hold and release the first locking portion 236.

[0193] In another example, the arms 132 of the first holding portion 130 can move away from the central axis CA in the direction from the distal end to the proximal end, and the protrusions 134 of the first holding portion 130 can protrude away from the central axis CA. In this case, the first locking portion 236 can be held outward (away from the central axis CA) by dispersing the entire first holding portion 130 outward, and the first locking portion 236 can be released by driving the first holding portion 130 inward (closer to the central axis CA), thereby making it easy to hold and release the first locking portion 236.

[0194] However, this embodiment example is not limited to this, and based on the idea that the first holding portion 130 forms a structure such as a snap fit, hook, latch, or pin to hold the held member, and the held member is released by moving the snap fit, hook, latch, or pin away from its original position, the arm 132 of the first holding portion 130 and the protrusion 134 of the first holding portion 130 may move closer to or protrude in other directions if a snap fit can be formed.

[0195] In some examples, the protrusion 134 of the first holding portion 130 may have a surface facing the distal end. In some examples, the surface facing the distal end of the protrusion 134 may be approximately perpendicular to the central axis CA. The held member (e.g., the first locking portion 236 of the motion body 200 described below) may be held against movement toward the proximal end by being mounted on / abutting against the surface facing the distal end of the protrusion 134. When the arm 132 of the first holding portion 130 is driven so that the surface facing the distal end of the protrusion 134 moves away from its original position, i.e., so that it no longer abuts against the held member, the held member is released.

[0196] That is, the first holding portion 130 may be a structure such as a snap fit, a hook, a latch, or a pin formed on the first housing 100 (for example, the end portion 120 of the first housing 100). For example, the first holding portion 130 is formed into a structure that can be disassembled into at least two parts, such as a finger-shaped, straight-shaped, L-shaped, J-shaped, or Z-shaped part, and at least one part of it (for example, an arm connected to the first housing 100) is pivotable, and the other part (for example, a protrusion that protrudes outward from the arm and abuts against the held member) moves away from its initial position as it pivots, thereby releasing the hook, buckle, latch, support, or the like from the held member.

[0197] Fig. 9A is an exploded schematic view showing the first holding unit 130, the exercise body 200, and the first drive mechanism 30 according to this embodiment, Fig. 9B is a cross-sectional schematic view showing the exercise body 200 according to this embodiment being held, and Fig. 9C is a cross-sectional schematic view showing the exercise body 200 according to this embodiment being released. Note that Figs. 9B and 9C mainly show the holding and release of the exercise body 200 by the first holding unit 130, and do not show the first drive mechanism 30 or other components.

[0198] In some examples, as described above, the assist mechanism 20 may include the movement body 200 and the housing portion 250 provided in the movement body 200. The movement body 200 is releasably held relative to the first housing 100. In some examples, the movement body 200 may be releasably held by the first holding portion 130. After the movement body 200 is released, it can be driven toward the proximal end to push the medical instrument 800 housed in the housing portion 250 toward the host.

[0199] In some examples, a first drive unit 30 may be provided between the movement body 200 and the first housing 100 (see FIG. 9A). The first drive unit 30 can act on the movement body 200 toward the proximal end. After the movement body 200 is released, it can be driven toward the proximal end by the first drive unit 30 to push the medical instrument 800 housed in the housing 250 toward the host.

[0200] In another example, as described above, the administration device 1000 may not include the first drive unit 30. In this case, after the movement body 200 is released, the movement body 200 can be pushed toward the host by human force, and the medical device 800 housed in the housing unit 250 can also be pushed toward the host.

[0201] In some examples, the exercise body 200 may include a first base 210, a second base 220, and a sidewall 230 (see FIG. 9A) connecting the first base 210 and the second base 220. The first base 210 may be near the distal end, and the second base 220 may be near the proximal end, and the housing 250 may be provided in the second base 220.

[0202] In some examples, a hollow portion may be formed between the first bottom portion 210, the second bottom portion 220, and the sidewall 230. In some examples, the puncturing member 260 may be releasably provided within the hollow portion of the exercise body 200. In some examples, when the puncturing member 260 is released, it can move along the hollow portion of the exercise body 200. In this case, by forming a hollow portion with the first bottom portion 210, the second bottom portion 220, and the sidewall 230, providing the housing portion 250 in the second bottom portion 220, and providing the puncturing member 260 in the hollow portion, it is possible to facilitate movement of the puncturing member 260 relative to the housing portion 250 when released. As a result, when the medical device 800 is administered to a host, the puncturing member 260 is released and moves relative to the housing portion 250, allowing the puncturing member 260 to move away from the host.

[0203] In another example, the puncture member 260 may be fixed to the movement body 200. In this case, after the medical device 800 is administered to the host, the entire movement body 200 can be manually detached from the host, thereby detaching the puncture member 260 from the host.

[0204] In some examples, the first driving mechanism 30 may be provided between the first bottom portion 210 and the first housing 100. In some examples, the first bottom portion 210 may be provided with a positioning portion 212 (see FIG. 9A ) for positioning the first driving mechanism 30. In this case, the positioning portion 212 can more stably limit the position at which the first driving mechanism 30 acts on the movement body 200.

[0205] In some examples, the positioning portion 212 of the first bottom portion 210 may be a columnar protrusion that protrudes from the first bottom portion 210 along the central axis CA toward the distal end (see FIG. 9A ). In some examples, the positioning portion 212 may be cylindrical. In some examples, the positioning portion 212 may be solid cylindrical, and the first drive mechanism 30 may be fitted onto the outer periphery of the positioning portion 212. In another example, the positioning portion 212 may be hollow cylindrical, and the first drive mechanism 30 may be fitted onto the outer periphery of the positioning portion 212 or may be fitted onto the inner periphery of the positioning portion 212.

[0206] In some examples, the first drive mechanism 30 may have an energy storage state and an energy release state, and when the first drive mechanism 30 is switched from the energy storage state to the energy release state, the first drive mechanism 30 can release energy and act on the moving body 200 toward the proximal end. When the moving body 200 is held, the first drive mechanism 30 can be between the moving body 200 and the first housing 100 in the energy storage state, and when the moving body 200 is released, the first drive mechanism 30 can be switched from the energy storage state to the energy release state and act on the moving body 200 toward the proximal end.

[0207] In some examples, the first drive mechanism 30 may have a compressed state and an extended state, and when the first drive mechanism 30 is switched from the compressed state to the extended state, the first drive mechanism 30 may release energy. In some examples, the first drive mechanism 30 may be a compressible elastic member. In some examples, the first drive mechanism 30 may be a spring. In some examples, one end of the first drive mechanism 30 may be fitted onto the positioning portion 212 of the first bottom portion 210.

[0208] In some examples, the end portion 120 may have a positioning portion 122 (see FIG. 8B ). In some examples, the positioning portion 122 may be cylindrical. In this case, the other end of the first drive mechanism 30 may be fitted onto the positioning portion 122. In some examples, the positioning portion 122 may be hollow cylindrical. In this case, the other end of the first drive mechanism 30 may be fitted onto or embedded into the positioning portion 122. In some examples, the positioning portion 122 may be composed of at least two stages of arc-shaped pillars. For example, in the embodiment shown in FIG. 8B , the positioning portion 122 may include an arc-shaped pillar 122a and an arc-shaped pillar 122b. In this case, the other end of the first drive mechanism 30 may be embedded between the arc-shaped pillar 122a and the arc-shaped pillar 122b.

[0209] However, the administration device 1000 of this embodiment is not limited thereto. In some examples, the administration device 1000 may not include the first drive mechanism 30. In this case, when the movement body 200 is released, the movement body 200 can be moved toward the proximal end by manually applying an action to the movement body 200.

[0210] In some examples, the moving body 200 may include a first locking portion 236 arranged to releasably interlock with the first retaining portion 130. This allows the moving body 200 to be releasably held to the first retaining portion 130 by the fit between the first locking portion 236 and the first retaining portion 130.

[0211] In some examples, the first locking portion 236 may be provided on the side wall 230 of the exercise body 200. That is, the first locking portion 236 may be provided on the side wall 230 of the exercise body 200 (see FIG. 9A). The first locking portion 236 can fit with the first holding portion 130 to hold the exercise body 200 in the first housing 100.

[0212] In some examples, the number of first locking portions 236 may be one or more, for example, 1, 2, 3, or 4. In some examples, the number of first locking portions 236 may be the same as the number of first retaining portions 130. In the embodiment shown in FIG. 9A, the number of first locking portions 236 may be two, and the first locking portion 236 may include a first locking portion 236a and a first locking portion 236b.

[0213] In some examples, the first locking portion 236 may be formed as a snap-fit ​​structure. Specifically, the first locking portion 236 may have a surface facing the proximal end, and the first holding portion 130 holds the movement body 200 by mounting, abutting, or joining to this surface, and the movement body 200 can be released by the first holding portion 130 moving away from this surface. In other words, the first holding portion 130 and the first locking portion 236 may be formed as an interlocking structure, in which the projections of the first holding portion 130 and the first locking portion 236 in the direction along the central axis CA have an overlapping portion, the first holding portion 130 holds the first locking portion 236 by the overlapping portion, and the first holding portion 130 releases the first locking portion 236 by moving the first holding portion 130 and / or the first locking portion 236 away from each other to eliminate the overlapping portion. In some examples, the first retaining portion 130 and / or the first locking portion 236 are driven away from each other, causing the first locking portion 236 to be released by the first retaining portion 130.

[0214] In some examples, the first locking portion 236 may be spaced apart substantially parallel to the central axis CA in the direction from the proximal end to the distal end, or spaced apart against the central axis CA. In this case, the first locking portion 236 may be closer to the central axis CA than the first retaining portion 130, which makes it easier to fit and interlock with the first retaining portion 130, which is gathered inward.

[0215] In another example, the first locking portion 236 may approach substantially parallel to or toward the central axis CA in the direction from the proximal end to the distal end. In this case, the first locking portion 236 can be farther from the central axis CA than the first retaining portion 130, which makes it easier to fit and interlock with the first retaining portion 130 that extends outward.

[0216] In some examples, the first locking portion 236 may be formed, for example, to be recessed from the outer surface of the side wall 230 toward the central axis CA. In some examples, the first locking portion 236 may be formed as a hollow structure, for example, a through-hole that penetrates the side wall 230 in a direction approximately perpendicular to the central axis CA. In some examples, the first locking portion 236 may be formed such that the periphery of the first bottom portion 210 protrudes from the side wall 230 in a direction perpendicular to the central axis CA, in which case the first bottom portion 210 and the side wall 230 may be fixedly connected. In other examples, the first locking portion 236 may be shaped like an inverted hook or L.

[0217] This embodiment example is not limited to this, and as described above, the idea of ​​the present invention is to form a structure such as a snap fit, hook, latch, or pin between the first retaining portion 130 and the first locking portion 236 to interlock them, in this case the first locking portion 236 has a surface facing the proximal end of the administration device 1000, and the first retaining portion 130 retains the first locking portion 236 by joining the surface facing the proximal end of the first locking portion 236 and the surface facing the distal end of the first retaining portion 130 to each other, and the first retaining portion 130 releases the first locking portion 236 by separating the surface facing the proximal end of the first locking portion 236 from the surface facing the distal end of the first retaining portion 130 from each other.

[0218] 9B and 9C, in the embodiment shown in FIGS. 9B and 9C, the first holding portion 130 may be L-shaped, and the first locking portion 236 may be formed as a hollow structure in the side wall 230. When the exercise body 200 is held, i.e., as shown in FIG. 9B, the protrusion 134 of the first holding portion 130 is positioned within the hollow structure of the first locking portion 236, thereby supporting and holding the exercise body 200. When the exercise body 200 is released, i.e., as shown in FIG. 9C, the arm 132 of the first holding portion 130 pivots away from the central axis CA, moving the protrusion 134 away from the central axis CA. The protrusion 134 leaves the hollow structure of the first locking portion 236, releasing the exercise body 200, and the exercise body 200 moves toward the proximal end under the action of the first driving mechanism 30.

[0219] 9B and 9C, in the embodiment shown in Fig. 9B and 9C, the arm 132 of the first holding portion 130 may move toward the central axis CA in the direction from the distal end to the proximal end. In this case, by driving the arm 132 of the first holding portion 130 along the direction of the central axis CA, the arm 132 is pivoted, and the protrusion 134 is moved away from the central axis CA, and the protrusion 134 is released from the hollow structure of the first locking portion 236, thereby releasing the movement body 200.

[0220] In addition, in some examples, the administration device 1000 may further include a first trigger mechanism 50 (see FIG. 7C ) arranged to separate the first holding portion 130 from the first locking portion 236 to release the moving body 200. This allows the first trigger mechanism 50 to easily release the moving body 200.

[0221] In some examples, the administration device 1000 may further include a first trigger mechanism 50 (see FIG. 7C ). The first trigger mechanism 50 is arranged to trigger the first holding portion 130, causing the exercise body 200 to be released by the first holding portion 130. In some examples, the first trigger mechanism 50 may be arranged to drive the first holding portion 130 and / or the first locking portion 236 away from each other, thereby releasing the exercise body 200. For example, the first trigger mechanism 50 may be arranged to drive the first holding portion 130 away from the central axis CA, thereby releasing the hold of the first locking portion 236, thereby releasing the exercise body 200. In other words, the first trigger mechanism 50 may be arranged to drive the first holding portion 130 and / or the first locking portion 236, causing them to move away from each other and releasing the first locking portion 236.

[0222] 10A is an exploded schematic view showing end 120 of first housing 100 and first trigger mechanism 50 according to this embodiment, FIG. 10B is a schematic perspective view showing a second viewpoint of end 120 of first housing 100 according to this embodiment, FIG. 10C is a schematic bottom view showing end 120 of first housing 100 according to this embodiment, FIG. 10D is a schematic plan view showing end 120 of first housing 100 according to this embodiment, FIG. 10E is a schematic perspective view showing first trigger mechanism 50 according to this embodiment, FIG. 10F is a schematic bottom view showing first trigger mechanism 50 according to this embodiment, FIG. 10G is a schematic cross-sectional view showing first trigger mechanism 50 and end 120 according to this embodiment before attachment, and FIG. 10H is a schematic cross-sectional view showing first trigger mechanism 50 and end 120 according to this embodiment after attachment.

[0223] In some examples, first trigger mechanism 50 may include a pressing portion 502, a driving portion 504, and an attachment portion 506 (see FIG. 10A ). First trigger mechanism 50 may be attached to end portion 120 by attachment portion 506. By applying an action to pressing portion 502, driving portion 504 drives first holding portion 130, which then releases movement body 200, thereby releasing movement body 200. In some examples, pressing portion 502 may be substantially disk-shaped.

[0224] In some examples, the drive portion 504 of the first trigger mechanism 50 may extend substantially along the direction of the central axis CA. In some examples, the first trigger mechanism 50 is arranged to be movable along the direction of the central axis CA. In this case, by driving the drive portion 504 of the first trigger mechanism 50 along the central axis CA of the administration device 1000, the first holding portion 130 can be driven with a simple operation so as to move away from the first locking portion 236.

[0225] In some examples, when projected in a direction along the central axis CA, the drive portion 504 of the first trigger portion 50 may at least partially overlap with the first holding portion 130 (for example, may at least partially overlap with the arm 132 of the first holding portion 130), and when the first trigger portion 50 moves in a direction along the central axis CA, the first holding portion 130 may be driven to move away from the first locking portion 236. This allows the first holding portion 130 to release the first locking portion 236 with a simple operation.

[0226] In another example, when projected in the direction along the central axis CA, the drive portion 504 of the first trigger portion 50 and the first locking portion 236 may at least partially overlap, and when the first trigger portion 50 moves along the direction of the central axis CA, the first locking portion 236 is driven to move away from the first holding portion 130. This allows the first locking portion 236 to be released with a simple operation.

[0227] In some examples, the number of mounting portions 506 may be one or more, for example, 1, 2, 3, or 4. In the embodiment shown in FIG. 10E, the mounting portion 506 may be mounting portion 506a and mounting portion 506b. In some examples, the multiple mounting portions 506 may be distributed symmetrically around the periphery of the central axis CA. In the embodiment shown in FIG. 10E, the mounting portions 506a and 506b are distributed symmetrically on both sides of the central axis CA. In some examples, the mounting portion 506 may be formed on the periphery of the pressing portion 502.

[0228] In some examples, the mounting portion 506 may extend from the pressing portion 502 toward the proximal end substantially along the central axis CA. In some examples, the mounting portion 506 may have an arm 512 that is generally aligned in the direction of the central axis CA and a protrusion 514 that protrudes from the arm 512 toward the central axis CA in a direction substantially perpendicular to the central axis CA (see FIG. 10E ). In some examples, the arm 512 of the mounting portion 506 may extend from the pressing portion 502 toward the proximal end substantially along the central axis CA.

[0229] In some examples, the arm 512 of the mounting portion 506 may be elastic. In some examples, the arm 512 of the mounting portion 506 may tend to contract toward the central axis CA in a direction from the distal end to the proximal end. That is, in a natural state (i.e., when not subjected to an external force), when comparing the end of the arm 512 closer to the proximal end with the end of the arm 512 closer to the distal end, the end of the arm 512 closer to the proximal end is closer to the central axis CA. In other examples, the arm 512 may be approximately parallel to the central axis CA. In some examples, when an action is applied to the arm 512 along a direction approximately perpendicular to the central axis CA, the arm 512 may pivot. For example, when an action is applied to the arm 512 toward the central axis CA along a direction approximately perpendicular to the central axis CA, the arm 512 may pivot such that the end of the arm 512 closer to the proximal end moves in a direction away from the central axis CA.

[0230] In some examples, the protrusion 514 of the mounting portion 506 may have a distal-facing surface. In some examples, the distal-facing surface of the protrusion 514 may be approximately perpendicular to the central axis CA. A member that fits with the mounting portion 506 (e.g., the offset portion 124 and the joint portion 126 of the end portion 120, described next) may be mounted / abutted against the distal-facing surface of the protrusion 514 to mount and couple to the mounting portion 506.

[0231] That is, mounting portion 506 may have a snap fit or latch structure formed on first trigger mechanism 50. For example, mounting portion 506 may be formed into a structure that can be disassembled into at least two parts, such as a finger-shaped, straight-line-shaped, L-shaped, J-shaped, or Z-shaped structure, at least one part of which (e.g., arm 512 connected to pressing portion 502) is pivotable, and another part (e.g., protrusion 514 protruding outward from arm 512 and abutting against an attachment coupling member) may be attached and coupled to an attachment coupling member (e.g., bias portion 124 and joint portion 126 of end portion 120, which will be described next) as it pivots, and may be, for example, a hook, buckle, latch, support, or the like.

[0232] In some examples, the end 120 may include a biasing portion 124 and a joint portion 126 (see FIGS. 10B and 10C ). In some examples, there may be a gap between the biasing portion 124 and the joint portion 126. In this case, the mounting portion 506 can enter the mounting position through the gap between the biasing portion 124 and the joint portion 126. In some examples, the number of biasing portions 124 and joint portions 126 of the end 120 may be more than one, for example, one, two, three, or four. In some examples, the number of biasing portions 124 and joint portions 126 of the end 120 may be the same as the number of mounting portions 506. In the example shown in FIGS. 10B and 10C , the biasing portion 124 may be biasing portion 124a and biasing portion 124b, and the joint portions 126 may be 126a and 126b.

[0233] In some examples, the distance between offset portion 124 and central axis CA may be greater than the distance between joint 126 and central axis CA. In some examples, offset portion 124 may gradually approach central axis CA in a direction along central axis CA toward the proximal end. In some examples, an end of offset portion 124 near the proximal end may be in contact with or slightly overlap with joint 126 when projected in a direction along central axis CA.

[0234] 10G and 10H, the attachment and coupling between the mounting portion 506, the biasing portion 124, and the joint portion 126 will be further described. Before the attachment and coupling, the distance between the protrusion of the mounting portion 506a and the protrusion of the mounting portion 506b may be slightly smaller than or substantially equal to the distance between the joint portions 126a and 126b in a direction substantially perpendicular to the central axis CA (see FIG. 10G). After the attachment and coupling, that is, by moving the mounting portion 506 along the central axis CA toward the proximal end, the mounting portion 506 can pass through the gap between the biasing portion 124 and the joint portion 126, and the arm 512 of the mounting portion 506 is pressed toward the central axis CA by the biasing portion 124, so that the distance between the protrusion of the mounting portion 506a and the protrusion of the mounting portion 506b gradually decreases and becomes smaller than the distance between the joint portions 126a and 126b. In this case, the pressing action of biasing portion 124 can cause the surface of mounting portion 506 facing the distal end of protrusion 514 to engage with joint portion 126, thereby interlocking mounting portion 506 with joint portion 126 and connecting first trigger mechanism 50 to end portion 120 (see FIG. 10H).

[0235] That is, the first trigger mechanism 50 and the end portion 120 can be attached and coupled by a structure such as a snap fit or a latch.

[0236] In some examples, first trigger mechanism 50 may further include rib groove 507. End 120 may include end rib 128. In some examples, the depth of rib groove 507 may be approximately the same as the thickness of end rib 128, and the width of rib groove 507 may be approximately the same as the width of end rib 128. In this case, the fit between rib groove 507 and end rib 128 can provide a guide during the attachment process. The fit between rib groove 507 and end rib 128 can also effectively prevent unintentional rotation of first trigger mechanism 50 attached to end 120.

[0237] In some examples, the rib grooves 507 and the end ribs 128 may extend substantially along the direction of the central axis CA. In some examples, the number of rib grooves 507 may be one or more, such as 1, 2, 3, or 4. For example, in the embodiment shown in FIGS. 10E and 10F , the rib grooves 507 may be rib groove 507a, rib groove 507b, rib groove 507c, and rib groove 507d. Correspondingly, the number of end ribs 128 may be one or more, or may be the same as the number of rib grooves 507. In the embodiment shown in FIG. 10B , the end ribs 128 may be end rib 128a, end rib 128b, end rib 128c, and end rib 128d.

[0238] Fig. 10I is a schematic cross-sectional view showing the first holding unit 130 according to this embodiment before it is triggered by the first trigger mechanism 50, and Fig. 10J is a schematic cross-sectional view showing the first holding unit 130 according to this embodiment after it has been triggered by the first trigger mechanism 50. Note that Figs. 10I and 10J mainly show the triggering of the first holding unit 130 by the first trigger mechanism 50.

[0239] In some examples, as described above, the drive unit 504 of the first trigger mechanism 50 can drive the first holding unit 130 to release the hold of the exercise body 200 by the first holding unit 130, thereby releasing the exercise body 200.

[0240] In some examples, the driving portion 504 may be formed as a columnar structure extending from the pressing portion 502 toward the proximal end substantially along the central axis CA (see FIG. 10E). In some examples, the number of driving portions 504 may be one or more, for example, 1, 2, 3, or 4. In some examples, the number of driving portions 504 may be the same as the number of first holding portions 130. In the embodiment shown in FIG. 10E, the driving portion 504 may include a driving portion 504a and a driving portion 504b.

[0241] In some examples, a through structure corresponding to the first holding portion 130 is formed in the end portion 120 in a direction substantially along the central axis CA (see FIG. 10B, FIG. 10C, or FIG. 10D). In some examples, when projected in a direction along the central axis CA, the projection surface of the through structure can cover the projection surface of the drive portion 504.

[0242] 10I and 10J, the triggering of the first holding portion 130 by the driving unit 504 will be described in detail. As described above, the first holding portion 130 is gradually converged toward the central axis CA in a direction toward the proximal end along the central axis CA. The driving unit 504 is arranged to drive the first holding portion 130 to move one end of the first holding portion 130 closer to the proximal end away from the central axis CA, thereby releasing the holding of the exercise body 200. In some examples, the distance between the driving unit 504a and the driving unit 504b in a direction substantially perpendicular to the central axis CA may be slightly greater than the distance between the first holding portion 130a and the first holding portion 130b.

[0243] Before the driving unit 504 drives the first holding unit 130, the proximal ends of the first holding unit 130a and the first holding unit 130b are brought together and interlocked with the first locking unit 236 to hold the exercise body 200 (see FIG. 10I). When the driving unit 504 drives the first holding unit 130 (for example, by pressing the pressing unit 502 in a direction toward the proximal end), the driving action of the driving unit 504 causes the first holding unit 130a and the first holding unit 130b to gradually open outward (i.e., move away from the central axis CA), and the protrusion 134 of the first holding unit 130 moves away from the first locking unit 236. The interlock between the first holding unit 130 and the first locking unit 236 is released, and the exercise body 200 is released (see FIG. 10J).

[0244] FIG. 11A is a schematic perspective view showing a second example of the end portion 120 according to this embodiment, FIG. 11B is a schematic plan view showing the second example of the end portion 120 according to this embodiment, FIG. 11C is a schematic bottom view showing the second example of the first trigger mechanism 50 according to this embodiment, and FIG. 11D is a schematic bottom view showing the third example of the first trigger mechanism 50 according to this embodiment.

[0245] In some examples, the end body 121 may have a solid structure. That is, the end body 121 may not have a through hole. In some examples, the end 120 may have a positioning portion 122 (see FIG. 8B ) extending from the end body 121 toward the proximal end. In this case, one end of the first drive mechanism 30 may be fitted onto the positioning portion 212 of the movement body 200, and the other end of the first drive mechanism 30 may be fitted onto the positioning portion 122 of the end 120. In this way, the first drive mechanism 30 is disposed between the movement body 200 and the end 120.

[0246] In some examples, the first drive mechanism 30 may be a spring, which can provide a drive mechanism for the exercise body 200 with a simplified structural design.

[0247] In another example, the end body 121 may have a through structure (see FIGS. 11A and 11B). That is, the end body 120 may have a through hole 129. In some examples, the diameter of the through hole 129 may be approximately the same as the diameter of the first drive mechanism 30. In this case, one end of the first drive mechanism 30 may abut the movement body 200, and the other end of the first drive mechanism 30 may abut the first trigger mechanism 50. In some examples, the first trigger mechanism 50 may have a positioning portion 508 (see FIG. 10C ), and one end of the first drive mechanism 30 may be fitted onto the positioning portion 212 of the movement body 200, and the other end of the first drive mechanism 30 may be fitted onto the positioning portion 508 of the first trigger mechanism 50. In this case, pressing the pressing portion 502 not only triggers the first holding portion 130 to release the movement body 200, but also provides a driving force for the movement of the movement body 200 toward the proximal end.

[0248] In some examples, positioning portion 508 of first trigger mechanism 50 may be cylindrical. First drive mechanism 30 may be fitted onto the outside of positioning portion 508. In some examples, positioning portion 508 of first trigger mechanism 50 may be hollow cylindrical. First drive mechanism 30 may be fitted onto or embedded into positioning portion 508. In some examples, positioning portion 508 may include two or more arc-shaped pillars, and in the embodiment shown in FIG. 11D , positioning portion 508 may include arc-shaped pillar 508a and arc-shaped pillar 508b. First drive mechanism 30 may be embedded between arc-shaped pillar 508a and arc-shaped pillar 508b.

[0249] In some examples, an anti-misstep mechanism 520 (see FIG. 7C ) may be provided between first trigger mechanism 50 and end portion 120. In some examples, anti-misstep mechanism 520 may be hairpin-shaped. In this case, hairpin-shaped anti-misstep mechanism 520 can effectively prevent first trigger mechanism 50 from unintentionally moving toward the proximal end. In some examples, anti-misstep mechanism 520 may be provided between pressing portion 502 of first trigger mechanism 50 and first housing 100.

[0250] In some examples, an elastic member, such as a spring (not shown), may be further provided between the end portion 120 and the first trigger mechanism 50. In some examples, the spring provided between the end portion 120 and the first trigger mechanism 50 may be in a compressed state. Even in this case, the spring acts on the distal end to prevent unintentional movement of the first trigger mechanism 50 toward the proximal end. The spring provided between the end portion 120 and the first trigger mechanism 50 can also contribute to the first trigger mechanism 50 returning to its initial state after triggering the first holding portion 130. In this case, the first trigger mechanism 50 can automatically return to its initial state after triggering the first holding portion 130, thereby contributing to the provision of a reusable administration device 1000.

[0251] FIG. 12A is an exploded schematic diagram showing a first viewpoint of the second housing 140 and the auxiliary mechanism 20, FIG. 12B is an exploded schematic diagram showing a second viewpoint of the second housing 140 and the auxiliary mechanism 20, FIG. 12C is a cross-sectional schematic diagram showing the attachment of the auxiliary mechanism 20 to the second housing 140, and FIG. 12D is a schematic diagram showing the lid 190 according to this embodiment.

[0252] In some examples, the first bottom portion 210 and the sidewall 230 of the exercise body 200 may be integrally molded. In other examples, the first bottom portion 210 of the exercise body 200 may be separably attached to the sidewall 230.

[0253] In some examples, the first bottom portion 210 may have a connecting portion 214 (see FIG. 12A ). In some examples, the number of connecting portions 214 may be one or more, for example, one, two, three, or four. In some examples, the side wall 230 may have a movement body limiting portion 238 (described below). The movement body limiting portion 238 can impose a restriction on the puncture member 260 provided within the movement body 200, preventing the puncture member 260 from unintentionally rotating. In some examples, the movement body limiting portion 238 may be formed as a groove and / or a ridge. In some examples, the movement body limiting portion 238 may be two ridge portions arranged in parallel and a groove located between the two ridge portions. The connecting portion 214 is joined to the ends of the two ridge portions of the movement body limiting portion 238, thereby connecting to the side wall 230.

[0254] In some examples, the second housing 140 may include a first limiting mechanism 150 and a second limiting mechanism 170. In some examples, the first limiting mechanism 150 and the second limiting mechanism 170 may be in communication with each other. In some examples, the first limiting mechanism 150 and the second limiting mechanism 170 may have a hollow columnar structure. In some examples, the first limiting mechanism 150 releasably holds the moving subject 200 and can limit the movement path of the moving subject 200. In some examples, the second limiting mechanism 170 can limit the attachment position of the medical device 800.

[0255] That is, in the administration device 1000 according to this embodiment, the housing 10 includes a first housing 100 having a first holding portion 130 and a second housing 140 that can be attached to the first housing 100. The second housing 140 has a first limiting mechanism 150 and a second limiting mechanism 170 that communicate with each other. The second limiting mechanism 170 is arranged to limit the attachment position of the medical device 800. The auxiliary mechanism 20 is attached to the first limiting mechanism 150 and may be movable along the first limiting mechanism 150 when the exercise main body 200 is released by the first holding portion 130. In this case, the first limiting mechanism 150 of the second housing 140 limits the movement of the exercise main body 200, and the second limiting mechanism 170 of the second housing 140 limits the attachment position of the medical device 800, which is advantageous for more accurate administration of the medical device 800 to the host.

[0256] In some examples, the first limiting mechanism 150 may have a limiting portion 151. The limiting portion 151 may impose a limit on the movement body 200 to prevent unintended rotation of the movement body 200. In some examples, the limiting portion 151 may be a groove and / or a ridge. In some examples, the limiting portion 151 may include a ridge 154 provided on the inner wall of the first limiting mechanism 150 and extending substantially along the central axis CA. In some examples, the limiting portion 151 may further include a groove 152 provided on the inner wall of the first limiting mechanism 150 and extending substantially along the central axis CA. In some examples, the length of the ridge 154 and the groove 152 may be smaller than the height of the first limiting mechanism 150, and the ridge 154 and the groove 152 may be substantially collinear in the direction of the central axis CA. In some examples, the restricting portions 151 may further include notches 156 provided in the first limiting mechanism 150, and the notches 156, the ridges 154, and the grooves 152 may be formed sequentially along the same straight line from the proximal end to the distal end. In some examples, the number of restricting portions 151 may be one or more, for example, 1, 2, 3, or 4. In some examples, the multiple restricting portions 151 may be uniformly distributed on the sidewall of the first limiting mechanism 150.

[0257] In some examples, the ridge 154 of the limiting portion 151 can fit into a restricted portion 232 (described below) of the exercise body 200, which includes a groove structure, to prevent unintentional rotation of the exercise body 200. In some examples, the exercise body 200 can be attached to the first limiting mechanism 150 along the groove 152, which can provide a guide during attachment. Also, in some examples, the notch 156 can be used to provide a joining space for the protrusion 234 (described below) of the exercise body 200.

[0258] In some examples, the first limiting mechanism 150 may further include reinforcing ribs 158 (see FIG. 12B ) provided on the inner wall. In some examples, the reinforcing ribs 158 may extend substantially along the direction of the central axis CA. In some examples, the number of reinforcing ribs 158 may be multiple, such as 2, 3, 4, 6, etc. In some examples, the reinforcing ribs 158 may be uniformly distributed on the inner wall of the first limiting mechanism 150.

[0259] In some examples, the first limiting mechanism 150 may further include a protrusion 160 (described in detail later) provided on the inner wall.

[0260] In some examples, the first limiting mechanism 150 can limit the stroke of the exercise body 200 in the direction along the central axis CA. In this case, by limiting the stroke of the exercise body 200 in the direction along the central axis CA using the first limiting mechanism 150, the medical device 800 housed in the housing 250 can be more accurately pushed out a predetermined distance, and the medical device 800 can be more accurately administered to the host.

[0261] In some examples, when projected in a direction along the central axis CA, the housing 250 and the wall of the first limiting mechanism 150 may at least partially overlap, and one end of the moving body 200 closer to the distal end may at least partially overlap with the wall of the first limiting mechanism 150 (see FIG. 12C ). In this case, by at least partially overlapping the housing 250 and the moving body 200 with the wall of the first limiting mechanism 150, the stroke of the moving body 200 along the first limiting mechanism 150 can be effectively limited with a simplified structure.

[0262] In some examples, a protrusion protruding away from the central axis CA along a direction substantially perpendicular to the central axis CA is provided at one end of the moving body 200 near the distal end. In this case, a snap fit is formed between the protrusion and the wall of the first limiting mechanism 150, thereby effectively restricting the moving body 200 from moving excessively toward the proximal end.

[0263] Additionally, in some examples, the first limiting mechanism 150 can prevent rotation of the exercise body 200. In this case, by preventing rotation of the exercise body 200, unintentional rotation of the puncture member 260 can be prevented during administration.

[0264] In some examples, the first limiting mechanism 150 may include grooves and / or ridges provided continuously or discontinuously on the inner wall along the direction of the central axis CA. In this case, by engaging the movement body 200 with the grooves and / or ridges of the first limiting mechanism 150, it is possible to effectively prevent the movement body 200 from unintentionally rotating within the first limiting mechanism 150.

[0265] In some examples, the movement body 200 may include grooves and / or ridges provided on the outer wall of the side wall 230 substantially along the direction of the central axis CA. In this case, the grooves and / or ridges of the movement body 200 may be engaged with the grooves and / or ridges of the first limiting mechanism 150, thereby effectively preventing the movement body 200 from unintentionally rotating within the first limiting mechanism 150.

[0266] In some examples, the first limiting mechanism 150 and the second limiting mechanism 170 may have a hollow cylindrical shape, and the inner diameter of the first limiting mechanism 150 may be equal to or smaller than the inner diameter of the second limiting mechanism 170. In this case, by providing the first limiting mechanism 150 and the second limiting mechanism 170 with a hollow cylindrical shape, the auxiliary mechanism 20 can easily move along the first limiting mechanism 150 and the second limiting mechanism 170.

[0267] Also, in some examples, when the moving body 200 is released, the moving body 200 can move along the first limiting mechanism 150, and the containing part 250 can move along the second limiting mechanism 170. In this case, by moving the moving body 200 along the first limiting mechanism 150 and moving the containing part 250 along the second limiting mechanism 170, the medical device 800 contained in the containing part 250 can be administered more accurately to a desired position on the host's body surface.

[0268] In some examples, a restricted portion 232 may be provided on the side wall 230 of the moving body 200 (see FIGS. 12A and 12B). The restricted portion 232 fits with the restricting portion 151 of the first limiting mechanism 150 to prevent unintentional rotation of the moving body 200. In some examples, the restricted portion 232 may include a groove 235 formed on the outer wall of the side wall 230. In some examples, the groove 235 may be formed between two parallel ridges. In some examples, the restricted portion 232 may further include an arm 233 formed by extending from the side wall 230 toward the distal end along the direction of the groove 235. In some examples, the restricted portion 232 may further include a protrusion 234 protruding from the arm 233 away from the central axis CA along a direction approximately perpendicular to the central axis CA. In some examples, the number of restricted portions 232 may be one or more, for example, 1, 2, 3, or 4. In some examples, the number of restricted portions 232 may be the same as the number of restricting portions 151. In some examples, the multiple restricted portions 232 may be uniformly distributed on the side wall 230. In some examples, the arms 233 may be elastic.

[0269] In some examples, when projected in a direction approximately perpendicular to the central axis CA, the projection plane of the protrusion 234 of the restricted portion 232 may be farther from the central axis CA than the projection of the notch 156 of the limiting portion 151. Also, the projection of the ridge 154 and the projection of the groove 235 may approximately join. Also, the projection of the protrusion 234 and the projection of the groove 152 may approximately join. In some examples, the length and / or width of the accommodating portion 250 may be greater than the diameter of the first limiting mechanism 150.

[0270] 12C , an action is applied toward the movement body 200 along the direction of the central axis CA, and the movement body 200 is attached to the first limiting mechanism 150 via the second limiting mechanism 170. The protrusion 234 can slide into the groove 152, thereby providing a guide assembly mechanism. When the protrusion 234 abuts against the ridge 154, the ridge 154 presses the protrusion 234, elastically deforming the arm 233, so that the protrusion 234 can be moved toward the central axis CA and continue to slide along the ridge 154. When the protrusion 234 protrudes from the first limiting mechanism 150 toward the distal end in the direction of the central axis CA, the arm 233 returns to its initial state, and the protrusion 234 protrudes from the first limiting mechanism 150 in a direction approximately perpendicular to the central axis CA.

[0271] The groove 235 of the exercise body 200 attached and coupled to the first limiting mechanism 150 may engage with the ridge portion 154 of the first limiting mechanism 150. This can limit the direction in which the ridge portion 154 extends when the exercise body 200 moves along the first limiting mechanism 150. The engagement between the groove 235 and the ridge portion 154 can also provide a rotation prevention mechanism that prevents the exercise body 200 from unintentionally rotating within the first limiting mechanism 150. In this case, unintentional rotation is effectively prevented when the puncture mechanism 260 is inserted subcutaneously into the host along with the exercise body 200, thereby reducing discomfort experienced by the host during the administration process.

[0272] Also, as described above, when projected in a direction along the central axis CA, the projection of the protrusion 234 is farther from the central axis CA than the projection of the notch 156. In this case, when the motion body 200 is attached and coupled to the first limiting mechanism 150, the projection 234 and the notch 156 form a snap-fit ​​connection, thereby limiting the amount of displacement that the motion body 200 advances toward the proximal end.

[0273] As described above, the length and / or width of the housing 250 connected to the second bottom 220 of the exercise body 200 in the direction substantially perpendicular to the central axis CA is greater than the diameter of the first limiting mechanism 150. In this case, when the exercise body 200 is attached and coupled to the first limiting mechanism 150, the housing 250 can limit the amount of displacement of the exercise body 200 toward the distal end.

[0274] In some examples, the second limiting mechanism 170 may include an upper base 172, a lower base 176, and a side portion 174 (see FIG. 12B ) connecting the upper base 172 and the lower base 176. In some examples, the upper base 172 may be formed to extend outward from one end near the proximal end of the first defining mechanism 150 in a direction substantially perpendicular to the central axis CA. The side portion 174 may be a hollow tubular structure, and the extension direction of the side portion 174 may be substantially parallel to the central axis CA. The lower base 176 may be formed to extend outward from one end near the proximal end of the side portion 174 in a direction substantially perpendicular to the central axis CA.

[0275] In some examples, the width by which the lower base portion 176 protrudes from the side portion 174 along a direction substantially perpendicular to the central axis CA may be substantially equal to the thickness of the peripheral portion 110 of the first housing 100.

[0276] In some examples, the second limiting mechanism 170 may include a rib groove 178 (see FIG. 12B ) provided on the side portion 174. In some examples, the number of rib grooves 178 may be one or more, for example, one, two, three, or four. In some examples, the rib groove 178 may be formed such that two ridges extending substantially along the direction of the central axis CA are provided side by side on the side portion 174, and the rib groove 178 is formed between the two side by side ridges.

[0277] In some examples, the rib grooves 178 can fit into the peripheral ribs 112 of the peripheral portion 110 to attach and couple the first housing 100 and the second housing 140. In some examples, the number of rib grooves 178 and the number of peripheral ribs 112 can be the same. In some examples, the peripheral ribs 112 can be inserted into the rib grooves 178 so as to be inserted substantially along the direction of the central axis CA. In some examples, the inner contour of the peripheral portion 110 is substantially the same as the outer contour of the second limiting mechanism 170. When the first housing 100 and the second housing 140 are moved toward each other substantially along the direction of the central axis CA, the peripheral ribs 112 can enter the rib grooves 178 to attach and couple the first housing 100 and the second housing 140.

[0278] In some examples, the second limiting mechanism 170 may further include mounting holes 180 (see FIG. 12B ) provided in the upper bottom portion 172. In some examples, the number of mounting holes 180 may be one or more, for example, one, two, three, or four. In some examples, the number of mounting holes 180 may be the same as the number of connecting posts 114 of the first housing 100. The mounting holes 180 can fit with the connecting posts 114 to attach and couple the first housing 100 and the second housing 140. The connecting posts 114 can be butted against the mounting holes 180.

[0279] In some examples, the second limiting mechanism 170 may further include a flange 183 (see FIG. 12B). In some examples, the upper bottom portion 172 of the second limiting mechanism 170 may further include an openwork 186 (see FIG. 12B). In this case, when the administration device 1000 and the cassette device 2000 are attached and coupled, the openwork 186 balances the internal and external air pressures, facilitating coupling of the administration device 1000 and the cassette device 2000.

[0280] In some examples, the housing 250 may move along the second limiting mechanism 170. In some examples, when operating the administration device 1000, the second limiting mechanism 170 can be attached to a body surface of a host to limit the attachment position of the medical device 800.

[0281] In some examples, the second limiting mechanism 170 may further include a magnet 184 (see FIG. 12B ) provided on the upper base 172. In some examples, the second limiting mechanism 170 may further include a magnet fixing portion 185 provided on the upper base 172, and the magnet fixing portion 185 may be used to fix the magnet 184. In some examples, the magnet fixing portion 185 may be two or more pillar-shaped protrusions along the direction of the central axis CA. The magnet 184 may be sandwiched between the multiple pillar-shaped protrusions. In this case, the magnet 184 provided on the second limiting mechanism 170 fits with a switch module 884 of the medical device 800 to control the on-state of the switch module 884. Specifically, when the movement body 200 is held, the distance between the medical device 800 contained in the storage section 250 and the magnet 184 on the second limiting mechanism 170 becomes closer, and the switch module 884 is subjected to the magnetic action of the magnet 184 and remains in a non-conductive state; when the movement body 200 is released, the movement body 200 moves toward the proximal end to administer the medical device 800 contained in the storage section 250 to the host, and the distance between the medical device 800 and the magnet 184 on the second limiting mechanism 170 becomes greater, and the switch module 884 is no longer subjected to the magnetic action of the magnet 184 and is switched to a conductive state.

[0282] In some examples, a side engagement groove 182 (see FIG. 12A ) is provided on the inner wall of the side portion 174 of the second limiting mechanism 170. In some examples, the number of side engagement grooves 182 may be multiple, for example, one, two, three, or four. In some examples, the multiple side engagement grooves 182 may be uniformly distributed on the inner wall of the side portion 174. In some examples, the side engagement groove 182 may extend approximately along the direction of the central axis CA. The side engagement groove 182 fits with a lid engagement portion 194 (described below) of the lid 190, allowing the second housing 140 to be attached and coupled to the lid 190.

[0283] In some examples, a first type rib 187 is provided on the inner wall of the side portion 174 of the second limiting mechanism 170. The first type rib 187 can function as a guide when the administration device 1000 fits with the cassette device 2000 (described below). In some examples, the number of first type ribs 187 may be multiple, for example, one, two, three, or four.

[0284] In some examples, a second type rib 188 is provided on the inner wall of the side portion 174 of the second limiting mechanism 170. The second rib 188 may serve as a pressing force, as described below, when the administration device 1000 fits into the cassette device 2000. In some examples, the number of second type ribs 188 may be multiple, for example, one, two, three, or four.

[0285] In some examples, a third type rib 189 is provided on the inner wall of the side portion 174 of the second limiting mechanism 170. The third type rib 189 may serve as a bias, as described below, when the administration device 1000 fits into the cassette device 2000. In some examples, the number of third type ribs 189 may be multiple, for example, one, two, three, or four.

[0286] In some examples, the housing 10 may further include a lid 190 (see FIG. 7C) that is detachably attached to the second housing 140.

[0287] In some examples, the lid 190 may include a lid bottom 192 and a lid engagement portion 194 (see FIG. 12D ) provided on the lid bottom 192. The lid engagement portion 194 can fit into the side engagement grooves 182 of the second housing 140 to attach and couple the lid 190 to the second housing 140. The number of lid engagement portions 194 may be multiple, for example, one, two, three, or four. The number of lid engagement portions 194 may be equal to the number of side engagement grooves 182. In the embodiment shown in FIG. 12D , the lid engagement portion 194 may include a lid engagement portion 194a and a lid engagement portion 194b. The lid engagement portion 194a and the lid engagement portion 194b may be distributed on opposite sides of the lid bottom 192 along the symmetry axis of the lid 190.

[0288] In some examples, the lid engagement portion 194 may include an arm extending from the lid bottom portion 192 toward a distal end substantially along the central axis CA, and a protrusion protruding from the end of the arm in a direction away from the central axis CA. The arm of the lid engagement portion 194 may be elastic. When the lid 190 is attached and coupled to the second housing 140, the protrusion of the lid engagement portion 194 can be engaged with the side engagement groove 182 of the second housing 140.

[0289] In some examples, the lid 190 may further include a lid support 196 (see FIG. 12D ). The axis of the lid support 196 may be approximately parallel to the central axis CA. In some examples, the lid support 196 may be formed by extending from the lid bottom 192 toward the distal end along the central axis CA. In some examples, when the exercise body 200 is held, the vertical distance between the surface facing the proximal end of the medical instrument 800 housed in the housing 250 and the lower bottom 176 of the second housing 140 may be approximately equal to the height of the lid support 196. In this case, when the lid 190 is attached and coupled to the second case 140, the medical instrument 800 housed in the housing 250 is supported by the lid support 196, which can further prevent the exercise body 200 from being unintentionally released due to, for example, incorrect operation.

[0290] In some examples, the lid 190 may further include a flange 198 (see FIG. 12D ). The position of the flange 198 of the lid 190 may correspond to the position of the flange 183 of the second housing 140. Specifically, when the lid 190 is attached and coupled to the second housing 140, the projected surface of the flange 198 and the projected surface of the flange 183 may substantially overlap when projected in a direction along the central axis CA, or the projected surface of the flange 198 may substantially cover the projected surface of the flange 183.

[0291] Figure 13A is an exploded schematic diagram showing a first perspective of the exercise main body 200 and the puncture member 260 of this embodiment example, Figure 13B is an exploded schematic diagram showing a second perspective of the exercise main body 200 and the puncture member 260 of this embodiment example, Figure 13C is a cross-sectional schematic diagram showing the puncture member 260 of this embodiment example when it is held, Figure 13D is a cross-sectional schematic diagram showing the puncture member 260 of this embodiment example when it is released, and Figure 13E is a cross-sectional schematic diagram showing the exercise main body 200 and the puncture member 260 of this embodiment example when temporarily attached.

[0292] In some examples, the movement body 200 and the puncture member 260 may be fixedly connected together. In other examples, the movement body 200 and the puncture member 260 may be detachably attached and coupled. In some examples, the puncture member 260 may be releasably held by the movement body 200.

[0293] In some examples, the exercise body 200 may have a first bottom portion 210 near the distal end, a second bottom portion 220 near the proximal end, and a sidewall 230 connecting the first bottom portion 210 and the second bottom portion 220. In some examples, a hollow portion may be formed between the first bottom portion 210, the second bottom portion 220, and the sidewall 230. In some examples, the housing portion 250 may be provided in the second bottom portion 220 and face the proximal end. In some examples, the puncture member 260 may be provided within the hollow portion. In some examples, the second bottom portion 220 may have a through-hole 226. In some examples, the puncture member 260 may pass through the through-hole 226.

[0294] In some examples, the puncture member 260 may be releasably disposed within the hollow portion. Furthermore, the puncture member 260 may be configured to be movable within the hollow portion relative to the movement body 200 upon release. In some examples, a second drive mechanism 40 may be disposed between the second bottom portion 220 of the movement body 200 and the puncture member 260. The second drive mechanism 40 is positioned to act on the puncture member 260 toward the distal end. When the puncture member 260 is released, the second drive mechanism 40 can act on the puncture member 260 toward the distal end so that the puncture member 260 moves away from the host. In some examples, the second drive mechanism 40 may be disposed between the support base 280 of the puncture member 260 and the second bottom portion 220 of the movement body 200. This allows the second drive mechanism 40 to contribute to moving the puncture member 260 away from the housing portion 250.

[0295] In some examples, as described above, the exercise body 200 may include a side wall 230 (see FIGS. 13A and 13B). In some examples, the exercise body 200 may include a limiting portion 238 provided on the side wall 230. The puncturing member 260 may have a restricted portion 285, which will be described later. When the puncturing member 260 is attached and coupled to the exercise body 200, the exercise body 200 can restrict the restricted portion 285 by the limiting portion 238 to restrict the movement of the puncturing member 260. In some examples, the number of limiting portions 238 may be one or more, for example, one, two, three, or four. In some examples, the multiple limiting portions 238 may be uniformly distributed on the inner wall of the side wall 230.

[0296] In some examples, the exercise body 200 may further include a second retaining portion 242 (see FIGS. 13A and 13B ). The puncturing member 260 may have a second locking portion 286. When the puncturing member 260 is attached and coupled to the exercise body 200, the exercise body 200 can retain the puncturing member 260 due to the interlock between the second retaining portion 242 and the puncturing member 260. In some examples, the retention of the puncturing member 260 by the second retaining portion 242 may be releasable. In some examples, the number of second retaining portions 242 may be one or more, for example, one, two, three, or four. In one example, the multiple second retaining portions 242 may be uniformly distributed on the side wall 230.

[0297] Additionally, in some examples, the exercise body 200 may be arranged to prevent rotation of the puncture member 260. In this case, preventing the puncture member 260 from unintentionally rotating during administration can improve the user experience during administration of the medical device 800. In some examples, the exercise body 200 can prevent the puncture member 260 from unintentionally rotating during administration by using the restriction portion 238.

[0298] In addition, in some examples, the movement body 200 may include grooves and / or ridges provided on the inner wall of the side wall 230 substantially along the direction of the central axis CA. In this case, the grooves and / or ridges provided on the inner wall of the side wall of the movement body 200 fit into the grooves and / or ridges of the puncture member 260, thereby effectively preventing the puncture member 260 from unintentionally rotating during the administration process. That is, in some examples, the limiting portion 238 of the movement body 200 may be a groove and / or ridge provided on the inner wall of the side wall 230 substantially along the direction of the central axis CA.

[0299] In some examples, the limiting portion 238 of the movement body 200 may be formed as a groove structure (see FIGS. 13A and 13B). In some examples, the limiting portion 238 may include two ridges arranged side by side on the inner wall of the side wall 230 substantially along the direction of the central axis CA, and a groove formed between the two ridges.

[0300] In some examples, the exercise body 200 may have a notch 242 that is approximately aligned with the direction of the central axis CA. In this case, by providing the exercise body 200 with the notch 242 aligned with the direction of the central axis CA, it is possible to facilitate the action of the puncture member 260 provided in the hollow portion of the exercise body 200.

[0301] In some examples, the inner wall of the first limiting mechanism 150 may be provided with a protrusion 160 that can protrude toward the central axis CA through the notch 242. In this case, when the movement body 200 moves along the first limiting mechanism 150, the protrusion 160 provided on the inner wall of the first limiting mechanism 150 can act on the puncturing member 260 through the notch 242 of the movement body 200, thereby providing a trigger mechanism for the puncturing member 260 with a simplified structure.

[0302] In some examples, the second retaining portion 242 of the exercise body 200 may be a notch formed in the side wall 230 (see FIGS. 13A and 13B). In some examples, the second retaining portion 242 may extend substantially along the central axis CA and have a first notch 244 and a second notch 246 that communicate with each other. The first notch 244 is closer to the proximal end, and the second notch 246 is closer to the distal end. In some examples, the widths of the first notch 244 and the second notch 246 may be different. In some examples, the width of the first notch 244 may be greater than the width of the second notch 246.

[0303] In some examples, the housing portion 250 may have a restraining portion 252 for restraining the attachment portion 860. In this case, by restraining the attachment portion 860 of the medical device 800 housed in the housing portion 250 by the restraining portion 252, the medical device 800 can be housed more firmly.

[0304] In some examples, the restraining portion 252 of the housing 250 may include an arm 254 and a protrusion 256. The arm 254 may extend outward from the bottom of the housing 250 in approximately the same direction as the side portions. In some examples, the arm 254 and the side portions of the housing 250 may be located in approximately the same circumferential direction. In some examples, the arm 254 may be elastic. In some examples, the arm 254 may be movable toward the central axis CA. In some examples, the protrusion 256 may be a protrusion provided at the end of the arm 254. In some examples, the protrusion 256 may protrude toward the central axis CA. In this case, the restraining portion 252 can hold the medical device 800 housed in the housing 250, and the medical device 800 can be more firmly housed.

[0305] In some examples, the number of restrictions 252 may be one or more, such as 1, 2, 3, or 4. In some examples, the constraints 252 may be evenly distributed along the sides of the housing 250.

[0306] In some examples, the puncturing member 260 may include a sharp object 270 and a support base 280 that supports the sharp object 270 (see FIGS. 13A and 13B). In some examples, the support base 280 of the puncturing member 260 is provided in the hollow portion of the movement body 200, the housing 250 is provided in the second bottom portion 220, the second bottom portion 220 has a through hole 226, and the sharp object 270 may pass through the through hole 226 of the second bottom portion 220. In this case, by providing the sharp object 270 to pass through the through hole 226 of the second bottom portion 220, the sharp object 270 can be joined to the medical device 800 housed in the housing portion 250, and the puncturing member 260 can easily place the medical device 800 at least partially under the skin of the host.

[0307] In some examples, the exercise body 200 may further include a structure 224 (see FIG. 13C ) for positioning the second drive mechanism 40, provided on the second bottom portion 220. In some examples, 224 may be columnar. In some examples, 224 may be hollow cylindrical. In this case, the second drive mechanism 40 is positioned by being fitted onto 224, thereby limiting the drive position of the second drive mechanism 40.

[0308] Furthermore, in some examples, when the puncturing member 260 is held, the distance between the support base 280 and the first bottom 210 may be equal to or greater than the length by which the sharp object 270 protrudes from the housing portion 250. In this case, by making the distance between the support base 280 and the first bottom 210 equal to or greater than the length by which the sharp object 270 protrudes from the housing portion 250, it is possible to provide a movement space for the puncturing member 260 to move away from the host, and it is possible to reduce unintended damage caused by the puncturing member 260 to the host.

[0309] In some instances, the sharp 270 and the support 280 may be integrally molded. In other instances, the sharp 270 and the support 280 may be arranged to be removably attached together, which may facilitate separate sterilization of the sharp 270.

[0310] In some examples, the restricted portion 285 of the puncture member 260 may be formed as a ridge structure (see FIG. 13B). In some examples, the restricted portion 285 may include two grooves arranged side by side on the side wall of the support seat 280 approximately along the direction of the central axis CA, and a ridge formed between the two grooves. In some examples, the number of restricted portions 285 may be one or more, for example, one, two, three, or four. In some examples, the number of restricted portions 285 may be equal to the number of restricting portions 238.

[0311] In some examples, the support base 280 may include grooves and / or ridges provided on the outer wall substantially along the direction of the central axis CA. In this case, the grooves and / or ridges of the support base 280 fit into grooves and / or ridges on the inner wall of the side wall of the exercise body 200, thereby effectively preventing unintentional rotation of the puncture member 260. In other words, the restricted portion 285 of the puncture member 260 may be formed as grooves and / or ridges provided on the outer wall substantially along the direction of the central axis CA. The restricted portion 285 of the puncture member 260 fits into the restricting portion 238 of the exercise body 200, thereby preventing unintentional rotation of the puncture member 260.

[0312] In some examples, the puncturing member 260 may include a second locking portion 286 arranged to releasably interlock with the second holding portion 242. This allows the puncturing member 260 to be releasably held in the second holding portion 242 by fitting the second locking portion 286 into the second holding portion 242. In some examples, the second locking portion 286 may be provided on the support base 280 of the puncturing member 260.

[0313] In some examples, the second locking portion 286 may include an arm 287 extending substantially along the direction of the central axis CA, and a protrusion 288 linked to the arm 287 and protruding away from the central axis CA substantially along a direction perpendicular to the central axis CA. In this case, when the puncturing member 260 is disposed in the hollow portion of the exercise body 200, the second locking portion 286 abuts against the notch 242 of the exercise body 200, thereby holding the puncturing member 260 in a simplified structure. In some examples, the arm 287 of the second locking portion 286 may be elastic along a direction substantially perpendicular to the central axis CA of the administration device 1000.

[0314] That is, in some examples, the exercise body 200 may have a notch 242 that is substantially aligned with the direction of the central axis CA. In some examples, when the puncture member 260 is held, the protrusion 288 of the second locking portion 286 may pass through the notch 242. In this case, by abutting the protrusion 288 of the second locking portion 286 with the notch 242 of the exercise body 200, the second locking portion 286 can be held with a simplified structure.

[0315] Furthermore, in some examples, when the puncture member 260 is released, the arm 288 of the second locking portion 286 may be pressed toward the central axis CA. This allows the second locking portion 286 to be released with a simple operation.

[0316] In some examples, the second holding portion 242 and the second locking portion 286 can be releasably interlocked by at least one of a snap fit, a hook, a latch, or a pin. In this case, the second holding portion 242 and the second locking portion 286 can be releasably interlocked by at least one of a snap fit, a hook, a latch, and a pin, thereby providing an interlocking method that is easy to release.

[0317] In some examples, the second locking portion 286 of the puncture member 260 may be formed as a shoulder structure (see FIGS. 13A and 13B). In some examples, the second locking portion 286 may include an arm 287 extending toward the distal end substantially along the direction of the central axis CA, and a protrusion 288 protruding from the end of the arm 287 in a direction substantially perpendicular to the central axis CA and away from the central axis CA. In some examples, the arm 287 may be elastic. In some examples, the arm 287 may gradually move away from the central axis CA in the direction toward the distal end along the central axis CA. In some examples, when projected along the direction of the central axis CA, the projection surface of the protrusion 288 and the projection surface of the first notch 244 may fully or partially overlap. In some examples, the number of second locking portions 286 may be one or more, for example, one, two, three, or four. In some examples, the number of second locking portions 286 and the number of second retaining portions 242 may be equal.

[0318] Also, in some examples, the width of the distal-facing surface of the protrusion 288 may be less than the width of the first notch 244 and greater than the width of the second notch 246 .

[0319] In some examples, when attaching the first limiting mechanism 150 and the exercise body 200, the protrusion 160 on the inner wall of the first limiting mechanism 150 can pass through the second notch 246 and the first notch 244 in sequence. In this case, the provision of the first notch 244 can provide a holding mechanism for the puncturing member 260, and the provision of the second notch 246 can provide a structure that is convenient for attachment. The protrusion 160 passes through the second notch 246 and enters the first notch 244, and the protrusion 288 of the second locking portion 286 protrudes through the first notch 244, thereby providing a holding mechanism for the puncturing member 260. Furthermore, the protrusion 160 can pass through the first notch 244 and abut against the protrusion 288 of the second locking portion 286, so that the protrusion 160 and the first notch 244 can provide a trigger mechanism that triggers the release of the second locking portion 286.

[0320] 13E, by applying an action to the puncturing member 260 toward the proximal end, the puncturing member 260 enters the hollow portion of the exercise body 200, and the restricted portions 285 of the puncturing member 260 and the limiting portions 238 of the exercise body 200 are aligned one by one, so that the restricted portions 285 fit into the limiting portions 238 (see FIG. 13E). This provides a guide for the attachment of the puncturing member 260 to the exercise body 200, while the puncturing member 260 attached to the exercise body 200 is restricted by the limiting portions 238, effectively preventing unintentional rotation.

[0321] 13C and 13D, when the protrusion 288 of the second locking portion 286 of the puncturing member 260 is moved into the first notch 244, the arm 287 is no longer pressed by the inner wall of the side wall 230, and therefore returns to its initial state, i.e., the projection surface of the protrusion 288 fully or partially overlaps the projection surface of the first notch 244 along the central axis CA, and the width of the surface facing the distal end of the protrusion 288 is greater than the width of the second notch 246, so that the protrusion 288 is positioned in the first notch 244, and the surface facing the distal end of the protrusion 288 abuts against the connection point between the first notch 244 and the second notch 246 (see FIG. 13C ), and is held within the hollow portion of the motion body 200. When the arm 287 is acted to pivot toward the central axis CA, the protrusion 288 moves toward the central axis CA, i.e., converges inward. In this case, the surface on the distal end side of the protrusion 288 no longer abuts against the connection point between the first notch 244 and the second notch 246, and the puncture member 260 is released by the movement body 200 (see FIG. 13D).

[0322] In some examples, after the puncture member 260 is released by the movement body 200, the second drive mechanism 40 drives the puncture member 260 toward the distal end so that the puncture member 260 moves away from the host.

[0323] In some examples, the second drive mechanism 40 and the first drive mechanism 30 may have the same or similar arrangement, and for the features of the second drive mechanism 40, please refer to the description of the features of the first drive mechanism 30. In some examples, the second drive mechanism 40 may be a spring, which allows for a simple structural design to provide a drive mechanism for the puncture member 260.

[0324] In some examples, the second drive mechanism 40 may be provided between the support base 280 and the second bottom portion 220, and when the puncturing member 260 is held, the distance between the support base 280 and the first bottom portion 210 is equal to or greater than the depth to which the sensor 820 is embedded subcutaneously. In this case, providing a sufficient amount of movement space for the puncturing member 260 can be advantageous in moving the puncturing member 260 away from the host.

[0325] In some examples, the puncture member 260 may have a positioning portion 289 (see FIG. 13C or FIG. 13D ) provided on the support base 280. In some examples, the positioning portion 289 may be a columnar structure. One end of the second drive mechanism 40 is fitted onto the positioning portion 289 of the puncture member 260, and the other end of the second drive mechanism 40 is fitted onto the positioning portion 212 of the movement body 200. In this way, the second drive mechanism 40 is provided between the movement body 200 and the puncture member 260.

[0326] In some examples, the administration device 1000 further provides a trigger mechanism that releases the interlock of the second holding portion 242 with the second locking portion 286 to release the puncturing member 260 from the movement body 200. That is, in some examples, the administration device 1000 further includes a second trigger mechanism that is arranged to separate the second holding portion 242 from the second locking portion 286 to release the puncturing member 260. This allows the puncturing member 260 to be easily released by the second trigger mechanism.

[0327] As described above, the second locking portion 286 is formed with a shoulder structure that can abut against the second holding portion 242, and is held to the second holding portion 242 by a snap fit. In some examples, such a trigger mechanism is provided so that the second holding portion 242 or the second locking portion 286 can be actuated to separate the second holding portion 242 and the second locking portion 286.

[0328] In some examples, a trigger mechanism acting on the second holding portion 242 and the second locking portion 286 may be provided in the movement path of the second locking portion 286. The trigger mechanism may be employed when the movement body 200 moves toward the proximal end. In some examples, the trigger mechanism may be a protrusion provided in the movement path of the second locking portion 286. In this case, when the second locking portion 286 passes through the protrusion, the arm 287 of the second locking portion 286 is pressed toward the central axis CA and elastically deforms, thereby separating the protrusion 288 of the second locking portion 286 from the first notch 244 and the second notch 246.

[0329] In some examples, as described above, a protrusion 160 is provided on the inner wall of the first limiting mechanism 150 (see FIG. 12B). When the moving body 200 moves along the first limiting mechanism 150, the first notch 244 and the second notch 246 of the moving body 200 can pass through the protrusion. Furthermore, when the puncturing member 260 is held in the hollow portion of the moving body 200, the second locking portion 286 of the puncturing member 260 is pressed by the protrusion 160 and deformed, and is separated from the connection point between the first notch 244 and the second notch 246, thereby releasing the puncturing member 260.

[0330] Furthermore, when the exerciser body 200 and the first limiting mechanism 150 are attached, the protrusion 160 can pass through the second notch 246 and the first notch 244 in sequence until the exerciser body 200 is attached and coupled to the first limiting mechanism 150. The protrusion 160 on the inner wall of the first limiting mechanism 150 and the first notch 244 and second notch 246 on the side wall 230 of the exerciser body 200 not only provide a trigger mechanism during movement but also do not affect the attachment of the exerciser body 200 and the first limiting mechanism 150.

[0331] Here, the administration process by the administration device 1000 will be described again, with the understanding that administration of the medical device 800 to the host by the administration device 1000 may include an administration step and a retraction step. In the administration step, the medical device 800 may be administered to the host, and in the retraction step, the puncture member 260 may be separated from the host.

[0332] In the administration stage, by pressing the pressing portion 502 of the first trigger mechanism 50, the driving portion 504 of the first trigger mechanism 50 is moved toward the proximal end, and when the driving portion 504 moves to the first holding mechanism 130, the driving portion 504 drives the first holding mechanism 130 to pivot away from the central axis CA (see Figures 10I and 10J), moving the first holding portion 130 away from the first locking portion 236 (see Figures 9B and 9C), thereby releasing the movement body 200, and the first driving mechanism 30 acts on the movement body 200 toward the proximal end, moving the movement body 200 toward the proximal end, and by the action of the puncture member 260, the medical device 800 contained in the container portion 250 is at least partially positioned subcutaneously in the host.

[0333] In some examples, the administration device 1000 may not include the first drive mechanism 30. In this case, after the movement body 200 is released, the movement body 200 may be manually driven toward the host, and the medical device 800 housed in the housing portion 250 may be administered to the host via the puncture member 260.

[0334] During the retraction phase, as the movement body 200 moves along the first limiting mechanism 150 toward the proximal end, the protrusion 160 on the inner wall of the first limiting mechanism 150 passes through the first notch 244 on the movement body 200 and approaches the second locking portion 286 of the puncturing member 260, and the protrusion 160 presses against the second locking portion 286, pivoting it in a direction toward the central axis CA and moving it away from the second retaining portion 242 (see Figures 13C and 13D).Then, the second driving mechanism 40 acts on the puncturing member 260 toward the distal end, moving the puncturing member 260 toward the distal end and away from the host.

[0335] In some examples, the puncturing member 260 and the movement body 200 may be fixedly connected. Also, in some examples, the administration device 1000 may not include the second driving mechanism 40. In this case, after the medical device 800 is administered to the host, the entire movement body 200 can be manually driven in a direction away from the host, and the puncturing member 260, which is fixedly connected to the movement body 200, can follow the movement body 200 and move away from the host.

[0336] Furthermore, during the retreating stage, the first driving mechanism 30 (or human power) can still act on the movement body 200 toward the host. In other words, for the first driving mechanism 30 configured as an elastic member (e.g., a spring), when the movement body 200 is driven toward the host and the medical device 800 housed in the housing 250 is attached to the body surface of the host, the first driving mechanism 30 can still be in an energy storage state. In this case, during the retreating stage, the medical device 800 is brought into close contact with the body surface of the host by the action of the first driving mechanism 30, which effectively reduces the possibility of the medical device 800 detaching from the host during the retreating stage.

[0337] Figure 14A is an exploded schematic diagram showing the puncture member 260 according to this embodiment, Figure 14B is a schematic diagram showing the attachment of the puncture member 260 according to this embodiment, Figure 14C is an enlarged schematic diagram showing the needle-shaped portion 272 according to this embodiment, and Figure 14D is a schematic diagram showing the attachment of the sharp object 270 and sensor 820 according to this embodiment.

[0338] As described above, in this embodiment, the puncturing member 260 may include a sharp object 270 and a support base 280 that supports the sharp object 270 (see FIG. 14A ). In some examples, the sharp object 270 and the support base 280 may be integrally formed. In another example, the sharp object 270 may be detachably attached to the support seat 280. In some examples, the sharp object 270 may have a groove, and all or part of the medical device 800 may be disposed in the groove. In some examples, the second drive mechanism 40 may act on the support base 280. In this case, disposing all or part of the medical device 800 in the groove of the sharp object 270 can facilitate subcutaneous placement of at least a portion of the medical device 800 by the puncturing member 260. In some examples, the fitting portion of the sensor 820 may be disposed in the groove 274 of the sharp object 270.

[0339] In some examples, the sharp object 270 may include a needle-shaped portion 272 (see FIG. 14A). In some examples, the needle-shaped portion 272 may be provided with a groove 274 extending along the length of the needle-shaped portion 272. The medical device 800 may be at least partially disposed within the groove 274 of the sharp object 270. In this case, the sensor 820 may be received within the groove 274 such that the sensor 820 follows the sharp object 270 and is positioned subcutaneously within the host.

[0340] In some examples, the sharp object 270 may include a cap portion 276 (see FIG. 14A ) connected to the needle portion 272. In some examples, the needle portion 272 may be attached to the support base 280 via the cap portion 276. In some examples, the cap 276 may include a first portion 277, a second portion 278, and a third portion 279 connected in sequence. In some examples, the first portion 277, the second portion 278, and the third portion 279 may be three columnar structures with different diameters. In some examples, the diameter of the second portion 278 may be smaller than the diameter of the first portion 277 and smaller than the diameter of the third portion 279, thereby forming an annular recess.

[0341] In some examples, the support base 280 may include a sharp object fixing portion 282 (see FIG. 14A ). In some examples, the number of sharp object fixing portions 282 may be multiple, for example, two, three, or four. Furthermore, the multiple sharp object fixing portions 282 may be arranged around the central axis CA so as to clamp the cap portion 276. In some examples, the support base 280 may have multiple finger portions gathered together, and the cap portion 276 may be releasably clamped by the multiple finger portions. In other words, the sharp object fixing portion 282 of the support base 280 may be formed as multiple finger portions gathered together. In this case, the cap portion 276 of the sharp object 270 fits into the multiple finger portions of the support base 280, thereby facilitating attachment and detachment of the sharp object 270 and the support base 280.

[0342] In some examples, the sharp object fixing portion 282 may gradually converge toward the central axis CA in a direction toward the proximal end along the central axis CA. This allows for a mechanism for clamping the cap portion 276. In some examples, the sharp object fixing portion 282 may include an arm 283 extending substantially along the direction of the central axis CA and a protrusion 284 protruding outward from the end of the arm 283 toward the central axis CA (see FIG. 14A). In some examples, the arm 283 may be elastic. When the sharp object 270 is attached and coupled to the support base 280, the protrusion 284 of the sharp object fixing portion 282 can fit into the annular recess of the cap portion 276. The first portion 277, the third portion 279, and the annular recess fit together to fix the sharp object 270. The first portion 277 and the third portion 279 each abut against the protrusion 284 from two directions. This makes it possible to prevent the sharp object 270 from unintentionally moving relative to the support base 280 along the central axis CA.

[0343] In some examples, the sharp object 270 of the puncture member 260 may be attached to the sensor 820. Specifically, referring to FIG. 14D , in some examples, the needle-like portion 272 of the sharp object 270 may be disposed within the sensor bonding hole 842 in the connection portion 840, and the fitting portion and the extension portion of the sensor 820 may be disposed within the groove 274 of the sharp object 270.

[0344] Figure 15A is a schematic perspective view showing the cassette device 2000 according to this embodiment, Figure 15B is a schematic plan view showing the cassette 2100, mounting table 2200 and fence structure 2400 of the cassette device 2000 according to this embodiment, and Figure 15C is a schematic plan view showing the stage 2300 of the cassette device 2000 according to this embodiment.

[0345] In some examples, the medical device 800 may be fully or partially sealed within the cassette device 2000. In some examples, the sensor 820 of the medical device 800 may be sealed within the cassette device 2000. In other examples, the sensor 820 and the connector 840 of the medical device 800 may be sealed together within the cassette device 2000. In other examples, the sensor 820, the connector 840, and the sharp 270 of the puncture member 260 may be sealed together within the cassette device 2000.

[0346] In some examples, the cassette device 2000 may include a cassette 2100 and a mounting base 2200 (see FIG. 15A ) provided inside the cassette 2100. A portion of the medical instrument 800, such as the sensor 820 and the connection portion 840 of the medical instrument 800, may be mounted on the mounting base 2200. In some examples, the mounting base 2200 may be formed as a columnar protrusion extending upward from the bottom of the cassette 2100. In some examples, the central axis of the mounting base 2200 may be approximately parallel to the central axis of the cassette 2100.

[0347] In some examples, the cassette 2100 may include a recessed edge 2110 (see FIG. 15A ) formed on the inner wall. In this case, when fitting the administration device 1000 and the cassette device 2000, which will be described later, the recessed edge 2110 of the cassette 2100 and the flange 183 of the second housing 140 fit together, making it possible to easily guide the administration device 1000 and the cassette device 2000 when they are combined.

[0348] In some examples, the planar contour of the mounting base 2200 may be substantially the same as the planar contour of the connecting portion 840, which makes it easier to mount the connecting portion 840. In some examples, the mounting base 2200 may have a hollow portion 2210 (see FIG. 15B ). This allows the portion of the sensor 820 protruding from the connecting portion 840 to be disposed within the hollow portion 2210 when the connecting portion 840 to which the sensor 820 is connected is mounted on the mounting base 2200. Furthermore, the central axis of the hollow portion 2210 may be substantially parallel to the central axis of the mounting base 2200.

[0349] In some examples, the mounting base 2200 may further include a fixing portion 2220 (see FIG. 15B) provided at the apex corner. In this case, the fixing portion 2220 is coupled to a recess at the apex corner of the connecting portion 840, thereby enabling the connecting portion 840 to be mounted more stably. Referring to FIG. 3, the connecting portion 840 may include a recess or notch provided at the apex corner.

[0350] In some examples, the mounting base 2200 may further include a storage space 2230 (see FIG. 15B ). In some examples, the storage space 2230 may be formed by providing a groove in the mounting base 2200 along the axis of the mounting base 2200. In some examples, a desiccant (not shown) may be stored in the storage space 2230. This can contribute to creating a dry environment within the cassette device 2000 and contribute to preserving the sensor 820.

[0351] In some examples, the cassette device 2000 may further include a stage 2300 (see FIG. 15A). The stage 2300 may be configured to be movable along the mounting table 2200.

[0352] In some examples, the stage 2300 may include an openwork portion 2310 (see FIG. 15C ). In some examples, the openwork outline of the openwork portion 2310 may be substantially the same as the outline of the mounting base 2200. In some examples, the stage 2300 may be configured to be movable along the mounting base 2200, and the openwork portion 2310 may be fitted onto the outer periphery of the mounting base 2200 during movement. In this case, when the upper surface of the mounting base 2200 is positioned below the upper or lower surface of the stage 2300, the sensor 820 mounted on the mounting base 2200 may be hidden, and when the upper surface of the mounting base 2200 is positioned above the upper surface of the stage 2300 as the stage 2300 is lowered, the sensor 820 may be exposed.

[0353] In some examples, the stage 2300 may include a clamping portion 2320. The clamping portion 2320 may include clamping portions 2320a and 2320b provided opposite each other on either side of the openwork portion 2310. When the sharp object 270 is also sealed within the cassette device 2000, the clamping portions 2320a and 2320b can clamp the cap portion 276 of the sharp object 270. In this case, by clamping the cap portion 276 of the sharp object 270 with the clamping portion 2320, the sharp object 270 can be more stably sealed within the cassette device 2000.

[0354] In some examples, the stage 2300 may include supported portions 2350 (see FIG. 15C ). Supporting the supported portions 2350 allows the stage 2300 to be positioned above the mounting table 2200. In some examples, the number of supported portions 2350 may be one or more, such as 1, 2, 3, or 4. In the embodiment shown in FIG. 15C , the supported portions 2350 may include 2350a, 2350b, 2350c, and 2350d. In some examples, the multiple supported portions 2350 may be symmetrically distributed around the periphery of the stage 2300, which can contribute to uniform support.

[0355] In some examples, the supported portion 2350 may include an arm 2351 that protrudes outward from the main body of the stage 2300 in a direction substantially perpendicular to the axis, a protrusion 2352 that protrudes further outward from the arm 2351 from the main body of the stage 2300 in a direction substantially perpendicular to the axis, and a side plate 2353 that protrudes laterally from the arm 2351 substantially along the circumferential direction of the stage 2300, and the arm 2351 may be elastic. In this case, the arm 2351 may be supported by the side plate 2353, and the arm 2351 can be moved toward the main body of the stage 2300 by acting on the protrusion 2352, and then moves away from the initial position in conjunction with the side plate 2353 and becomes unsupported. When the stage 2300 is no longer supported, the sensor 820 mounted on the mounting table 2200 can be exposed by acting on the stage 2300 toward the bottom of the cassette 2100. This facilitates subsequent processes, for example facilitating pick-up of the sensor 820 by the administration device 1000.

[0356] In some examples, the stage 2300 may further include a pressure-receiving portion 2330 (see FIG. 15C ). By pressing the pressure-receiving portion 2330, the stage 2300 can be moved along the mounting table 2200 toward the bottom of the cassette 2100. In some examples, the pressure-receiving portion 2330 may protrude outward from the main body of the stage 2300 in a direction substantially perpendicular to the axis. In some examples, the number of pressure-receiving portions 2330 may be one or more, for example, one, two, three, or four. In the embodiment shown in FIG. 15C , the pressure-receiving portions 2330 include 2330a, 2330b, 2330c, and 2330d. In some examples, the multiple pressure-receiving portions 2330 may be symmetrically distributed around the periphery of the stage 2300, which can contribute to uniform pressure distribution.

[0357] In some examples, the stage 2300 may further include a restricted portion 2360 (see FIG. 15C ). Adding a restriction to the restricted portion 2360 can further restrict movement of the stage 2300 along the mounting table 2200. In some examples, the restricted portion 2360 may be a ridge or groove provided on the periphery of the stage 2300. In some examples, the number of restricted portions 2360 may be one or more, for example, one, two, three, or four. In the embodiment shown in FIG. 15C , the restricted portion 2360 is two ridges arranged side by side on the periphery of the stage 2300 along the axial direction of the stage 2300, and a groove formed between the two ridges. In the embodiment shown in FIG. 15C , the restricted portion 2360 may include 2360 a, 2360 b, and 2360 c.

[0358] In some examples, cassette apparatus 2000 may further include a barrier structure 2400 (see FIG. 15A ), which may be positioned to support stage 2300 and to guide or limit the movement of stage 2300.

[0359] In some examples, the fence structure 2400 may include supports 2410 (see FIG. 15B ). The supports 2410 can support the supported portions 2350 of the stage 2300. In some examples, the supports 2410 can be protrusions that protrude inward from the main body of the fence structure 2400. The number and positions of the supports 2410 correspond to the number and positions of the stage supported portions 2350, e.g., they are the same in number and their projection planes along the axis at least partially overlap. In the example shown in FIG. 15B , the supports 2410 can include 2410 a, 2410 b, 2410 c, and 2410 d.

[0360] In some examples, the barrier structure 2400 may further include a limiting portion 2420 (see FIG. 15B). The limiting portion 2420 may limit the restricted portion 2360 of the stage 2300, thereby limiting the movement of the stage 2300. In some examples, the limiting portion 2420 may be a ridge-like protrusion that protrudes inward from the main body of the barrier structure 2400, and the ridge-like protrusion may fit into a groove in the restricted portion 2360. In the embodiment shown in FIG. 15B, the limiting portions 2420 may be 2420a, 2420b, and 2420c.

[0361] Figure 16A is a schematic diagram showing that the sensor 820 is placed on the mounting table 2200 in this embodiment, Figure 16B is a schematic diagram showing that the stage 2300 in this embodiment is higher than the mounting table 2200, and Figure 16C is a schematic diagram showing that the stage 2300 in this embodiment has moved lower than the mounting table 2200 toward the bottom of the cassette 2100.

[0362] In some examples, the barrier structure 2400 may further include a clearance portion 2430 (see FIG. 16A ). When the stage 2300 moves downward, the clearance portion 2430 can provide clearance space for the pressure-receiving portion 2330. In the embodiment shown in FIG. 16A , the clearance portion 2430 may include 2430a and 2430b.

[0363] 16A, 16B, and 16C, a sharp object 270, a sensor 820, and a connection part 840 are placed on a mounting base 2200. When the stage 2300 is located in the initial position, the sharp object 270 and the like may be hidden within an openwork portion 2310 of the stage 2300, and after the stage 2300 is driven toward the bottom of the cassette 2100, the mounting base 2200 passes through the openwork portion 2310 to expose the sharp object 270 and the like.

[0364] As described above, the supported portion 2350 of the stage 2300 (specifically, the side plate 2353) is supported by the support portion 2410 of the fence structure 2400, and is thereby held above the mounting table 2200, hiding the sharp portion 270 and the like. When an inward force is applied to the protruding portion 2352, the arm 2351 pivots inward, and moves inward in conjunction with the side plate 2353, thereby separating from the support portion 2410 and becoming unsupported. In this case, by applying a force toward the bottom of the cassette 2100 to the stage 2300, the stage 2300 can be moved downward relative to the mounting table 2200.

[0365] In some examples, the administration device 1000 can fit with the cassette device 2000 to pick up devices such as sharps 270, sensors 820, and connections 840 stored within the cassette device 2000.

[0366] FIG. 17 is a cross-sectional view showing the housing 10 according to this embodiment along a direction substantially perpendicular to the central axis CA.

[0367] Referring to FIG. 17, a first type rib 187, a second type rib 188, and a third type rib 189 are provided on the inner wall of the second limiting mechanism 170 of the housing 10.

[0368] The first type ribs 187 are arranged to fit into guide grooves (not shown) in the cassette device 2000 and assist pickup along a desired direction. In the embodiment shown in Fig. 17, the first type ribs 187 may include 187a, 187b, 187c, and 187d.

[0369] The third type ribs 189 may be arranged to fit over the protrusions 2352 of the supported portions 2350 of the stage 2300, and when the dispensing device 1000 is acted on toward the bottom of the cassette 2100, the second type ribs 188 abut against the protrusions 2352 of the supported portions 2350, driving the protrusions 2352 inward, and the arms 2351 pivot inward and move away from the supported position in conjunction with the side plates 2353. In some examples, the number of third type ribs 189 may be one or more, for example, one, two, three, or four.
