Description

[0001] This application is a divisional application of the patent application with the filing date of August 31, 2021 , application number 2021110169660 , and invention title An auxiliary device that can automatically retreat . Technical Field

[0002] The present disclosure relates to an auxiliary device. Background Art

[0003] For clinical diagnosis or personal health monitoring needs, for example, for diabetic patients, it is very necessary to continuously monitor the glucose concentration in interstitial fluid in real time on a daily basis, so as to adjust the glucose concentration in a timely manner, such as by adjusting diet or applying drug treatment, etc., thereby reducing and lowering the occurrence of complications caused by abnormal glucose concentration.

[0004] Currently, users usually use a glucose sensor that can be inserted under the skin and can react with glucose in interstitial fluid, and an electronic device that is applied to the skin and connected to the glucose sensor to monitor the glucose concentration in interstitial fluid. In order to insert the glucose sensor under the skin and apply the electronic device to the skin, an insertion device is usually required. Specifically, the insertion device may include a needle that can pierce the skin. The glucose sensor is inserted under the skin through the needle, and then the needle is separated from the glucose sensor and removed from the skin.

[0005] However, in the above prior art, the process of removing the needle from the skin requires manual driving. In this case, since it may be difficult to accurately control the timing of removing the needle from the skin, on the one hand, the operation of removing the needle from the skin may be cumbersome, and on the other hand, it may also cause the glucose sensor not to be inserted into the desired position. Summary of the Invention

[0006] In view of the above prior art situation, the present disclosure is completed, and its purpose is to provide an auxiliary device that can automatically retract a puncturing member and can more accurately control the timing of the puncturing member leaving the host.

[0007] To this end, the present disclosure provides an auxiliary device capable of automatic retraction, which is an auxiliary device for placing a medical device under the skin of a host. The auxiliary device includes a housing, an auxiliary mechanism, a driving mechanism, and a triggering mechanism. The housing includes a proximal end close to the host during operation and a distal end away from the host. The auxiliary mechanism includes a moving body configured to be movable relative to the housing, a receiving portion provided on the moving body and configured to receive and accommodate the medical device, a holding portion provided on the moving body, and a puncturing member releasably held by the holding portion and configured to be movable relative to the receiving portion when released. The driving mechanism is configured to act on the puncturing member in a direction toward the distal end. The triggering mechanism is configured to release the puncturing member from the holding portion. When the moving body approaches the proximal end, the medical device accommodated in the receiving portion is at least partially placed under the skin of the host through the puncturing member, and the triggering mechanism releases the puncturing member and the driving mechanism drives the puncturing member toward the distal end to move away from the host.

[0008] In the auxiliary device according to the present embodiment, the housing includes a proximal end close to the host during operation and a distal end away from the host. A receiving portion configured to receive and accommodate a medical device and a puncturing member configured to be movable relative to the receiving portion are provided on the moving body. When the moving body approaches the proximal end, the medical device is at least partially placed under the skin of the host, and the puncturing member is released and driven toward the distal end to move away from the host. In this case, when the medical device is placed under the skin of the host through the puncturing member, the puncturing member can be automatically moved away from the host through the triggering mechanism and the driving mechanism, thereby providing a mechanism for automatic retraction of the puncturing member and enabling more accurate control of the timing of the puncturing member moving away from the host.

[0009] In addition, in the auxiliary device according to the present embodiment, optionally, the puncturing member includes a locking portion configured to be releasably interlocked with the holding portion. Thus, the puncturing member can be releasably held by the holding portion through the cooperation of the locking portion and the holding portion.

[0010] In addition, in the auxiliary device according to the present embodiment, optionally, the holding portion and the locking portion are releasably interlocked by at least one of a buckle, a hook, a latch, or a pin. In this case, the holding portion and the locking portion are releasably interlocked by at least one of a buckle, a hook, a latch, or a pin, thereby providing a releasable interlocking method that is easy to release.

[0011] In addition, in the auxiliary device according to the present embodiment, optionally, the triggering mechanism is configured to separate the holding portion from the locking portion to release the puncturing member. Thus, the puncturing member can be conveniently released through the triggering mechanism.

[0012] In addition, in the auxiliary device according to the present embodiment, optionally, the housing includes a first outer shell and a second outer shell that can be assembled to the first outer shell. The second outer shell has a first limiting mechanism and a second limiting mechanism that communicate with each other. The second limiting mechanism is configured to limit the application position of the medical device. The auxiliary mechanism is assembled to the first limiting mechanism and the moving body can move along the first limiting mechanism. In this case, the movement of the moving body is limited by the first limiting mechanism of the second outer shell, and the application position of the medical device is limited by the second limiting mechanism of the second outer shell. Thereby, it is possible to more accurately place the medical device under the skin of the host.

[0013] In addition, in the auxiliary device according to the present embodiment, optionally, the moving body has a first bottom portion near the distal end, a second bottom portion near the proximal end, a side wall 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 side wall. The accommodating portion is provided on the second bottom portion and can move along the hollow portion when the puncturing member is released. In this case, the hollow portion is formed by the first bottom portion, the second bottom portion and the side wall, the accommodating portion is provided on the second bottom portion, and the puncturing member is provided in the hollow portion. Thereby, it is possible to facilitate the movement of the puncturing member relative to the accommodating portion when the puncturing member is released.

[0014] In addition, in the auxiliary device according to the present embodiment, optionally, the puncturing member includes a sharp object having a groove and a support seat for supporting the sharp object. The medical device can be wholly or partly placed in the groove of the sharp object. The driving mechanism is configured to apply an action to the support seat. In this case, by wholly or partly placing the medical device in the groove of the sharp object, it is possible to facilitate placing at least part of the medical device under the skin of the host through the puncturing member.

[0015] In addition, in the auxiliary device according to the present embodiment, optionally, the medical device includes a sensor that can be placed under the skin of the host and an application portion that is connected to the sensor and can be applied to the body surface of the host. In this case, the sensor that can be placed under the skin of the host and the application portion that can be applied to the body surface of the host are connected to the sensor. Thereby, it is possible to facilitate obtaining analyte information of tissue fluid.

[0016] In addition, in the auxiliary device according to the present embodiment, optionally, when the moving body moves along the first limiting mechanism, the accommodating portion moves along the second limiting mechanism. In this case, by making the moving body move along the first limiting mechanism and the accommodating portion move along the second limiting mechanism, it is possible to more accurately place the medical device accommodated in the accommodating portion under the skin of the host at a desired position.

[0017] Additionally, in the assistive device of this embodiment, the first limiting mechanism optionally limits the travel of the movable body along the central axis of the assistive device. In this case, by limiting the travel of the movable body along the central axis of the assistive device through the first limiting mechanism, the medical device contained in the receiving portion can be more accurately pushed a predetermined distance, thereby more accurately placing the medical device under the skin of the patient.

[0018] Additionally, in the assistive device of this embodiment, optionally, when projected along the central axis of the assistive device, the receiving portion at least partially overlaps with a wall of the first limiting mechanism, and the end of the moving body proximal to the distal end at least partially overlaps with the wall of the first limiting mechanism. In this case, by ensuring that the receiving portion and the moving body at least partially overlap with the wall of the first limiting mechanism, the range of movement of the moving body along the first limiting mechanism can be effectively limited while simplifying the structure.

[0019] In the assisting device according to this embodiment, the movable body may optionally include a cutout substantially along the central axis of the assisting device. In this case, the cutout provided in the movable body along the central axis of the assisting device facilitates application of the puncture member disposed within the hollow portion of the movable body.

[0020] Additionally, in the assisting device of this embodiment, a protrusion can optionally be provided on the inner wall of the first limiting mechanism, projecting toward the central axis of the assisting device through the cutout. In this case, when the moving body moves along the first limiting mechanism, the protrusion provided on the inner wall of the first limiting mechanism can act on the puncture member through the cutout of the moving body, thereby providing a triggering mechanism for the puncture member while simplifying the structure.

[0021] In addition, in the auxiliary device of this embodiment, the moving body is optionally configured to inhibit the rotation of the puncture member. In this case, by inhibiting the puncture member from rotating unexpectedly during the application process, the user experience during the application of the medical device can be improved.

[0022] In addition, in the auxiliary device according to this embodiment, the sharp object and the support seat are optionally configured to be detachably assembled and combined, thereby facilitating the separate sterilization of the sharp object.

[0023] In addition, in the auxiliary device according to the present embodiment, optionally, the locking portion is provided on the support base, and the locking portion includes an arm extending substantially along the central axis direction of the auxiliary device, and a protrusion that is linked with the arm and protrudes away from the central axis of the auxiliary device substantially along a direction orthogonal to the central axis of the auxiliary device. In this case, when the puncturing member is placed inside the hollow portion of the moving body, the locking portion is lapped with the incision of the moving body, thereby enabling the puncturing member to be held with a simplified structure.

[0024] In addition, in the auxiliary device according to the present embodiment, optionally, when the puncturing member is held, the protrusion of the locking portion passes through the incision. In this case, by lapping the protrusion of the locking portion with the incision of the moving body, the locking portion can be held with a simplified structure.

[0025] In addition, in the auxiliary device according to the present embodiment, optionally, when the puncturing member is released, the arm of the locking portion is pressed toward the central axis of the auxiliary device and the protrusion of the locking portion leaves the incision. Thereby, the locking portion can be released simply and conveniently.

[0026] In addition, in the auxiliary device according to the present embodiment, optionally, the support base of the puncturing member is provided inside the hollow portion, the accommodating portion is provided on the second bottom, the second bottom has a through hole, and the sharp object passes through the through hole of the second bottom. In this case, by arranging the sharp object to pass through the through hole of the second bottom, the sharp object can be engaged with the medical device accommodated in the accommodating portion, thereby facilitating at least partial placement of the medical device under the skin of the host through the puncturing member.

[0027] Furthermore, in the auxiliary device according to the present embodiment, optionally, when the puncturing member is held, the distance between the support base and the first bottom is not less than the length by which the sharp object protrudes from the accommodating portion. In this case, by setting the distance between the support base and the first bottom to be not less than the length by which the sharp object protrudes from the accommodating portion, a moving space can be provided for the puncturing member to leave the host, thereby reducing the undesired injury to the host caused by the puncturing member.

[0028] According to the present disclosure, a mechanism for automatic retraction of the puncturing member can be provided, and the timing of the puncturing member leaving the host can be controlled more accurately. Description of the Drawings

Detailed Embodiments

[0041] Hereinafter, with reference to the accompanying drawings, the preferred embodiments of the present disclosure will be described in detail. In the following description, the same reference numerals are given to the same components, and redundant descriptions are omitted. In addition, the drawings are only schematic diagrams, and the ratio of the dimensions between components or the shape of components, etc. may be different from the actual ones.

[0042] It should be noted that the terms "include" and "have" in the present disclosure and any variations thereof, for example, a process, method, system, product or device including or having a series of steps or units do not necessarily limit to those steps or units clearly listed, but may include or have other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0043] Embodiments of the present disclosure relate to an auxiliary device for a medical device, which can be used to place the medical device wholly or partly under the skin of a host. Through the auxiliary device involved in this embodiment, it is possible to help place the medical device under the skin of the host at a desired position.

[0044] The auxiliary device involved in this embodiment may also be referred to as, for example, a boosting device, a delivery device, an implantation device, a patch device, an application device, etc. It should be noted that each name is for representing the device involved in this embodiment for applying a medical device to a host, and should not be construed as restrictive.

[0045] Figure 1 FIG. shows an application overview of the medical device 800 and the auxiliary device 1000 involved in the example of this embodiment. In this embodiment, the medical device 800 can be applied to a host via the auxiliary device 1000 and be applied to a desired position, and the host can obtain physiological information through the medical device 800 applied to itself.

[0046] In addition, the present disclosure also provides a monitoring system. The monitoring system may include the medical device 800 capable of obtaining the physiological information of a host involved in this embodiment, and a reading device 900 communicatively connected to the medical device 800 (see Figure 1 ). The medical device 800 applied to the host can transmit the obtained physiological information to the reading device 900, for example, wirelessly, thereby facilitating the host to read and monitor its own physiological information.

[0047] In some examples, the medical device 800 can be a sensing device. In some examples, the medical device 800 can be an analyte sensor device, which can generate information about a specific analyte in a body fluid based on the body fluid, for example, react with the analyte in the body fluid and generate analyte information. In this case, by reacting the sensor with the analyte in the body fluid, it is possible to facilitate the acquisition of analyte information in the body fluid.

[0048] In this embodiment, the analyte targeted by the analyte sensor device can be one or more of glucose, acetylcholine, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase, creatine, creatinine, DNA, fructosamine, glutamine, growth hormone, hormone, ketone body, lactate, oxygen, peroxide, prostate-specific antigen, prothrombin, RNA, thyroid-stimulating hormone, or troponin.

[0049] Hereinafter, taking glucose as an analyte as an example, the medical device 800 involved in the example of this embodiment will be described. It should be noted that for other analytes, those skilled in the art can analyze other analytes with a slight modification to the medical device 800 used for glucose.

[0050] Figure 2 is a schematic diagram showing a first perspective of the medical device 800 according to an example of the present embodiment. Figure 3 is a schematic diagram showing a second perspective of the medical device 800 according to an example of the present embodiment. Figure 4 is a block diagram schematic of an electronic device of the medical device 800 according to an example of the present embodiment.

[0051] In some examples, the medical device 800 may include a sensor 820, a connection part 840, and an application part 860 (see Figure 2 or Figure 3 ). The sensor 820 may be detachably assembled to the application part 860. The sensor 820 may be connected to the application part 860 through the connection part 840. In some other examples, the medical device 800 may not include the connection part 840, and in this case, the sensor 820 may be directly connected to the application part 860.

[0052] In some examples, the sensor 820 may be partially or entirely placed under the skin of the host. In some examples, after the sensor 820 is placed under the skin, it may react with glucose in the subcutaneous tissue fluid to generate glucose information of the host. The application part 860 may be applied to the body surface of the host. In some examples, the application part 860 may also receive the glucose information generated by the sensor 820. In some examples, the application part 860 may also provide the electric energy required for the sensor 820 to obtain physiological information. Thus, it is beneficial for the sensor 820 to continuously monitor under the skin of the host.

[0053] In some examples, the sensor 820 may include an implantation part (not shown) and a connection part (not shown). The implantation part may be placed under the skin of the host and connected to the application part 860 through the connection part. In this case, by placing the implantation part under the skin of the host and connecting the implantation part to the application part 860 through the connection part, it is possible to facilitate the transmission of the obtained analyte information to an external device. In some examples, the connection part may be connected to the application part 860 via the connection part 840.

[0054] In some examples, the implanted portion of the sensor 820 can be elongated. In some examples, the implanted portion can be rigid. Thereby, it can be helpful to be placed subcutaneously in the host. In some other examples, the implanted portion can also be flexible. In this case, the foreign body sensation of the host can be reduced. In some examples, the length of the implanted portion can be from 1 mm to 10 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. After the implanted portion is implanted into the host, its depth can reach the dermal layer and be located between the tissues of the skin, so that the sensor 820 can collect glucose information in the interstitial fluid.

[0055] In some examples, the implanted portion can include a working electrode (not shown) and a counter electrode (not shown). In the present embodiment, a sensing layer including glucose enzyme can be provided on the working electrode. The sensor 820 placed subcutaneously can undergo an oxidation-reduction reaction between the glucose enzyme on the working electrode and glucose in the tissue fluid or blood, and form a circuit with the counter electrode to generate a current signal, and the current signal is analyzed and processed to obtain glucose concentration information. In some examples, the current signal generated by the sensor 820 can be transmitted to the patch portion 860.

[0056] In some examples, the implanted portion can further include a reference electrode (not shown). In some examples, the reference electrode can form a known and fixed potential difference with the tissue fluid or blood. In this case, the potential difference between the working electrode and the tissue fluid or blood can be measured by the potential difference formed by the reference electrode and the working electrode. Thereby, the voltage generated by the working electrode can be obtained more accurately. Thus, the electronic device 880 (described later) of the patch portion 860 can automatically adjust and maintain the stability of the voltage at the working electrode according to a preset voltage value, so that the measured current signal can more accurately reflect the glucose concentration information in the tissue fluid or blood. In some examples, the number of reference electrodes can be one or more, such as two.

[0057] In some examples, the connecting portion 840 can be generally columnar, such as quadrangular columnar. However, the examples of the present embodiment are not limited to this. In other embodiments, the connecting portion 840 can also be generally triangular columnar, hexagonal columnar, cylindrical, or hemispherical, etc. In addition, the receiving portion (not shown) of the patch portion 860 can also be formed into a shape matching the connecting portion 840 to be suitable for receiving the connecting portion 840. For example, the receiving portion of the patch portion 860 can be formed into a concave portion matching the shape of the connecting portion 840, and the connecting portion 840 can be fitted into the concave portion.

[0058] In some examples, the sensor 820 can be configured to be detachably assembled to the patch portion 860. In this case, the sensor 820 and the patch portion 860 can be separately encapsulated before the medical device 800 is received into the receiving portion 250, thereby facilitating the sterilization of the sensor 820 and the patch portion 860 in different ways.

[0059] In some examples, the patch portion 860 is configured to be attachable to the body surface of the host. In some examples, the patch portion 860 may further include an adhesive sheet 870 having adhesive properties (see Figure 2 or Figure 3 ). The patch portion 860 can be attached and fixed to the body surface of the host through the adhesive sheet 870. In some examples, the adhesive surface of the adhesive sheet 870 can be substantially equal to the bottom surface of the patch portion 860 close to the host. In other examples, the adhesive surface of the adhesive sheet 870 can also be slightly larger than the bottom surface of the patch portion 860 close to the host.

[0060] In some examples, the patch portion 860 may further include an electronic device 880 (see Figure 4 ). The electronic device 880 can 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 can also transmit the received glucose information to an external device, such as the reading device 900 to be described below. In addition, the electronic device 880 can also power the sensor 820.

[0061] In some examples, the electronic device 880 can include a power module 882, a switch module 884, and a processing module 886 (see Figure 4 ). The power module 882 can power the sensor 820 and / or the processing module 886, the switch module 884 can control the connection and disconnection between the power module 882 and the sensor 820 and / or the processing module 886, and the processing module 886 can process the signals (e.g., glucose information) generated by the sensor 820.

[0062] In addition, in some examples, the electronic device 880 may further include a storage module 888 (see Figure 4 ). The storage module 888 can store the signals generated by the sensor 820. In addition, in some examples, the electronic device 880 may further include a communication module 890 (see Figure 4 ). The communication module 890 can communicate with an external device (e.g., a smart terminal device). In some examples, the communication module 890 can be a Bluetooth module, an NFC module, a Wifi module, etc. In some examples, the smart terminal device can be a smart phone, a smart watch, a tablet computer, a computer, etc.

[0063] In some examples, after receiving the glucose information generated by the sensor 820, the electronic device 880 can immediately transmit it to an external device. This enables the external device to immediately process or display the glucose information. In other examples, after receiving the glucose information generated by the sensor 820, the electronic device 880 can also first store it in the storage module 888 and then transmit it to the external device at regular intervals. Thus, the power consumption caused by immediate transmission can be reduced.

[0064] In addition, in some examples, the power supply module 882 of the electronic device 880 can also be configured to supply electrical energy to the sensor 820. In some examples, when the electronic device 880 is in the initial mode, the connection between the power supply module 882 and the sensor 820 can be disconnected. When the electronic device 880 is activated to the working mode (i.e., when the switch module 884 is in the closed state), the power supply module 882 can be connected to the sensor 820 to supply electrical energy to the sensor 820.

[0065] In some examples, as described above, the patch portion 860 can be configured to communicate with an external device via wireless communication or wired communication. In this case, by configuring the patch portion 860 to be able to communicate with an external device, the analyte information acquired by the sensor 820 can be read in real time or at regular intervals. In some examples, the external device can be a reading device 900.

[0066] In some examples, as described above, the medical device 800 can be communicatively connected to the reading device 900. In some examples, the reading device 900 can be a display with communication functions. In some examples, the communication function of the reading device 900 can be implemented via wireless communication or wired communication. The wireless communication method can be Bluetooth, NFC, Wifi, etc. The wired communication method can be USB, optical fiber, etc.

[0067] In other examples, the reading device 900 can also be a smart terminal installed with an application program that matches the medical device 800. The smart terminal can be a notebook computer, a tablet computer, a smart phone, etc.

[0068] As described above, the medical device 800 involved in this embodiment can be applied to a host through the auxiliary device 1000. Hereinafter, with reference to the drawings, the auxiliary device 1000 involved in this embodiment will be described in detail.

[0069] Figure 5A is a schematic diagram showing the overall appearance of the auxiliary device 1000 involved in the example of this embodiment; Figure 5B is an exploded view showing the auxiliary device 1000 involved in the example of this embodiment. In Figure 5A andFigure 5B In [description], the line CA schematically represents the central axis of the auxiliary device 1000.

[0070] In the present embodiment, the auxiliary device 1000 may include a housing 10 that provides a movement space, and an auxiliary mechanism 20 configured to move within the movement space of the housing 10 (see Figure 5A and Figure 5B ). The housing 10 may have a proximal end that is close to the host during operation and a distal end that is far from the host. The auxiliary mechanism 20 may be releasably held in the housing 10 and may accommodate a medical device 800. The auxiliary mechanism 20 may be configured to move relative to the housing 10 and be driven toward the host when released to apply the medical device 800 to the host. It can be understood that herein, the "proximal end" may be understood as the end close to the host during operation, and the "distal end" may be understood as the end far from the host during operation.

[0071] In some examples, the housing 10 may have a movement space, and the auxiliary mechanism 20 may be releasably held in the housing 10. In some examples, the auxiliary mechanism 20 may move within the movement space of the housing 10 when released. Additionally, in some examples, the housing 10 may further define the application position of the medical device 800 on the body surface of the host.

[0072] In some examples, the housing 10 may include a first outer shell 100 and a second outer shell 140. A movement space may be formed after the first outer shell 100 and the second outer shell 140 are assembled and combined. The first outer shell 100 may releasably hold the auxiliary mechanism 20. The second outer shell 140 may define the application position of the medical device 800 on the body surface of the host and may define the movement path of the auxiliary mechanism 20. After the auxiliary mechanism 20 is released by the first outer shell 100, it may move relative to the second outer shell 140 along the movement path defined by the second outer shell 140 and apply the medical device 800 to the application position defined by the second outer shell 140. In the present embodiment, the axis of the first outer shell 100 and the axis of the second outer shell 140 may be substantially parallel to the central axis CA of the auxiliary device 1000.

[0073] In some examples, the auxiliary mechanism 20 may include a moving body 200, a receiving portion 250, and a puncturing member 260 (see Figure 5B)。The moving body 200 can be releasably held in the first housing 100, and the moving body 200 can be configured to move along a movement path defined by the second housing 140 when released. The accommodating portion 250 can be provided on the moving body 200 and can be configured to receive and accommodate the medical device 800, and the accommodating portion 250 can be driven toward an application position defined by the second housing 140. The puncturing member 260 can be provided on the moving body 200 in a manner that passes through the accommodating portion 250. After the moving body 200 is released, it can move toward the proximal end of the housing 10, and the accommodating portion 250 and the puncturing member 260 also move toward the proximal end of the housing 10 to apply the medical device 800 accommodated in the accommodating portion 250 to the host. In some examples, the puncturing member 260 can penetrate into the subcutaneous tissue of the host, so as to place the medical device 800 at least partially under the skin of the host.

[0074] In addition, in some examples, the auxiliary device 1000 may further include a first driving mechanism 30 (see Figure 5B ). The first driving mechanism 30 can be configured to act on the moving body 200 in a proximal direction. When the moving body 200 is released, the moving body 200 can be driven by the first driving mechanism 30 toward the proximal end to push the medical device 800 accommodated in the accommodating portion 250 toward the host, for example, to an application position defined by the second housing 140. In addition, the medical device 800 can be at least partially placed under the skin of the host through the puncturing member 260.

[0075] In other examples, the auxiliary device 1000 may not include the first driving mechanism 30. In this case, when the moving body 200 is released, the moving body 200 can also be manually driven to move toward the proximal end.

[0076] In addition, in some examples, the puncturing member 260 can be releasably provided on the moving body 200, and the puncturing member 260 can be configured to move relative to the accommodating portion 250 when released. For example, when the puncturing member 260 is released, it can move away from the host relative to the accommodating portion 250.

[0077] In addition, in some examples, the auxiliary device 1000 may further include a second driving mechanism 40 (see Figure 5B ). The second driving mechanism 40 can be configured to act on the puncturing member 260 in a distal direction. When the puncturing member 260 is released, the puncturing member 260 can be driven by the second driving mechanism 40 toward the distal end to move the puncturing member 260 away from the host.

[0078] In some other examples, the auxiliary device 1000 may also not include the second driving mechanism 40. In this case, the puncturing member 260 can be manually driven away from the host. For example, in some examples, the puncturing member 260 may also be integrally connected to the moving body 200, and the puncturing member 260 is moved away from the host by manually moving the moving body 200 in a direction away from the host.

[0079] In some examples, as described above, the housing 10 may include a first outer shell 100 (see Figure 5A or 5B). In some examples, the first outer shell 100 may include a peripheral portion 110 and an end portion 120 (see Figure 5B ).

[0080] Figure 6A is a perspective schematic view showing the peripheral portion 110 of the first outer shell 100 involved in the example of the present embodiment; Figure 6B is a perspective schematic view of a first perspective showing the end portion 120 of the first outer shell 100 involved in the example of the present embodiment. In some examples, the peripheral portion 110 may be formed as a hollow cylindrical shell that penetrates up and down along the central axis CA of the auxiliary device 1000 (see Figure 6A ). The end portion 120 may be disposed on the peripheral portion 110 in a manner close to 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.

[0081] In some examples, one or more ribbed protrusions may be provided on the inner wall of the first outer shell 100, and one or more ribbed grooves may be provided on the outer wall of the second outer shell 140. In some examples, when the second outer shell 140 is assembled to the first outer shell 100, one or more ribbed protrusions of the first outer shell 100 may be respectively embedded in one or more ribbed grooves of the second outer shell 140. In this case, through the matching of the ribbed protrusions and the ribbed grooves, it is possible to facilitate the assembly of the first outer shell 100 and the second outer shell 140.

[0082] In some examples, a peripheral rib 112 extending substantially along the direction of the central axis CA may be provided on the inner wall of the peripheral portion 110 (see Figure 6A ). In some examples, the number of the peripheral ribs 112 may be multiple, such as 2, 3, or 4. In Figure 6A the illustrated embodiment, the number of the peripheral ribs 112 is 4, and the peripheral ribs 112 may include a peripheral rib 112a, a peripheral rib 112b, a peripheral rib 112c, and a peripheral rib 112d. In some examples, the peripheral rib 112 may be used as a reinforcing rib to effectively improve the anti-deformation ability of the peripheral portion 110. In some examples, the peripheral rib 112 may also be used as a guiding rib to facilitate the assembly of the first outer shell 100 and the second outer shell 140 (described later).

[0083] In some examples, connecting columns 114 that are generally parallel to the central axis CA may also be provided on the inner wall of the peripheral portion 110 (see Figure 6A ). In some examples, the number of connecting columns 114 may be multiple, such as 2, 3, or 4. In Figure 6A the illustrated embodiment, the number of connecting columns 114 is 3, and the connecting columns 114 may include connecting column 114a, connecting column 114b, and connecting column 114c. In some examples, one end of the connecting column 114 near the proximal end of the auxiliary device 1000 may be a heat-type column end, that is, it can be in a molten state via heating and then can solidify via cooling. In this case, the connecting column 114 can be fitted with a hole provided on the second housing 140 and assembled and combined with the second housing 140 (described later).

[0084] In some examples, the end portion 120 may include an end portion main body 121 that is generally cylindrical (see Figure 6B ).

[0085] In some examples, the first housing 100 may include a first holding portion 130. In some examples, the first holding portion 130 may be configured to releasably hold the auxiliary mechanism 20. In some examples, the first holding portion 130 may be provided on the end portion 120 (see Figure 6B ). In some examples, the first holding portion 130 may extend along the central axis CA from the end portion main body 121 in the direction of the proximal end of the auxiliary device 1000. In this case, when the auxiliary mechanism 20 is held at the end portion 120, the auxiliary mechanism 20 may be located within the hollow portion of the peripheral portion 110, and when the auxiliary mechanism 20 is released, the auxiliary mechanism 20 may move generally along the axial direction of the peripheral portion 110. That is, when the auxiliary mechanism 20 is released, the auxiliary mechanism 20 may move generally along the central axis CA.

[0086] In some examples, the first holding portion 130 may be releasably interlocked with the held member (for example, the first locking portion 236 of the moving body 200 described later in the following text) by at least one of a buckle, a hook, a latch, or a pin. In this case, the first holding portion 130 and the first locking portion 236 are releasably interlocked by at least one of a buckle, a hook, a latch, or a pin, thereby providing a releasable interlocking method that is convenient.

[0087] In some examples, the number of the first holding portions 130 may be one or more, such as 1, 2, 3, or 4. In Figure 6BIn the illustrated embodiment, the number of the first holding portions 130 may be two, and the first holding portions 130 may include a first holding portion 130a and a first holding portion 130b. The first holding portion 130a and the first holding portion 130b may be equidistantly disposed on opposite sides of the central axis CA (see Figure 6B ).

[0088] 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. When the moving body 200 is held, the surface of the first holding portion 130 facing the distal end and the surface of the first locking portion 236 facing the proximal end may be engaged with each other. In some examples, when the moving body 200 is released, the surface of the first holding portion 130 facing the distal end and the surface of the first locking portion 236 facing the proximal end may be separated from each other.

[0089] In some examples, at least a portion of the first holding portion 130 may be L-shaped or hook-shaped. Thus, it is possible to facilitate the formation of a buckle or the like and interlock with the first locking portion 236.

[0090] 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 that is linked to the arm 132 and protrudes toward the central axis CA along a direction substantially orthogonal to the central axis CA (see Figure 6B ). 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 overlaps the first locking portion 236, by actuating the arm 132 to actuate the protrusion 134, the first holding portion 130 can be conveniently released from the first locking portion 236.

[0091] In addition, in some examples, a groove (not shown) extending substantially along the central axis CA may be provided on the arm 132 of the first holding portion 130. In some examples, the groove may face the central axis CA. In this case, the actuating portion 504 of the first triggering mechanism 50 (described later) can move along the groove and actuate the arm 132 of the first holding portion 130.

[0092] In some examples, the arm 132 of the first holding portion 130 can be elastic. In some examples, the arm 132 of the first holding portion 130 can be elastic in a direction substantially orthogonal to the central axis CA. In some examples, the arm 132 of the first holding portion 130 can tend to contract toward the central axis CA in the direction from the distal end to the proximal end. That is, in the natural state (i.e., the state without external force), compared with the end of the arm 132 near the proximal end and the end of the arm 132 near the distal end, the distance between the end of the arm 132 near the proximal end and the central axis CA is closer. In some other examples, the arm 132 can also be substantially parallel to the central axis CA. In some examples, when an action is applied to the arm 132 in a direction substantially orthogonal to the central axis CA, the arm 132 can pivot. For example, when an action is applied to the arm 132 in a direction substantially orthogonal to the central axis CA and away from the central axis CA, the arm 132 can pivot so that the end of the arm 132 near the proximal end moves away from the central axis CA. Thus, the held member can be released easily and simply.

[0093] In some examples, the arm 132 of the first holding portion 130 can approach the central axis CA in the direction from the distal end to the proximal end, and the protrusion 134 of the first holding portion 130 can protrude toward the central axis CA. In this case, by making the first holding portion 130 contract inward as a whole, the first locking portion 236 can be held on the inner side (close to the central axis CA), and by actuating the first holding portion 130 toward the outer side (away from the central axis CA), the first locking portion 236 can be released. Thus, it is convenient to hold and release the first locking portion 236.

[0094] In some other examples, the arm 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 protrusion 134 of the first holding portion 130 can protrude away from the central axis CA. In this case, by making the first holding portion 130 disperse outward as a whole, the first locking portion 236 can be held on the outer side (away from the central axis CA), and by actuating the first holding portion 130 toward the inner side (close to the central axis CA), the first locking portion 236 can be released. Thus, it is convenient to hold and release the first locking portion 236.

[0095] However, the examples of this embodiment are not limited to this. The concept of the present disclosure is that the first holding portion 130 forms a structure such as a buckle, a hook, a latch, or a pin to hold the held member, and releases the held member by moving the buckle, the hook, the latch, or the pin away from its original position. Based on this concept, the arm 132 of the first holding portion 130 and the protrusion 134 of the first holding portion 130 can also approach or protrude in other directions when they can form a buckle.

[0096] In some examples, the protrusion 134 of the first retaining portion 130 may have a surface facing the distal end. In some examples, the surface of the protrusion 134 facing the distal end may be substantially orthogonal to the central axis CA. The member to be retained (for example, the first locking portion 236 of the moving body 200 to be described below) can be retained and prevented from moving toward the proximal end by lapping / abutting against the surface of the protrusion 134 facing the distal end. When the arm 132 of the first retaining portion 130 is actuated to move the surface of the protrusion 134 facing the distal end away from its original position, i.e., no longer abutting against the member to be retained, the member to be retained will be released.

[0097] That is to say, the first retaining portion 130 can be a structure such as a buckle, hook, latch, or pin formed on the first housing 100 (for example, the end portion 120 of the first housing 100). For example, the first retaining portion 130 can be formed into a structure that can be at least decomposed into two parts, such as finger-shaped, one-shaped, L-shaped, J-shaped, Z-shaped, etc. At least a part of it (for example, the arm connected to the first housing 100) can pivot, and the other part (for example, the protrusion protruding outward from the arm and abutting against the member to be retained) can move away from the initial position along with the pivoting, thereby releasing the hooking, hanging, latching, propping, supporting, etc. of the member to be retained.

[0098] Figure 7A is an exploded schematic view showing the first retaining portion 130, the moving body 200, and the first driving mechanism 30 involved in the example of this embodiment; Figure 7B is a cross-sectional schematic view showing the moving body 200 being retained in the example of this embodiment; Figure 7C is a cross-sectional schematic view showing the moving body 200 being released in the example of this embodiment. It should be noted that in Figure 7B and Figure 7C mainly shows the retention and release of the moving body 200 by the first retaining portion 130, and does not show the first driving mechanism 30 and other components.

[0099] In some examples, as described above, the auxiliary mechanism 20 may include the moving body 200 and the accommodating portion 250 provided on the moving body 200. The moving body 200 can be releasably retained on the first housing 100. In some examples, the moving body 200 can be releasably retained by the first retaining portion 130. After the moving body 200 is released, it can be driven toward the proximal end to push the medical device 800 accommodated in the accommodating portion 250 toward the host.

[0100] In some examples, a first driving portion 30 may be provided between the moving body 200 and the first housing 100 (see Figure 7A)。The first driving part 30 can act on the moving body 200 in a proximal direction. After the moving body 200 is released, it can be driven by the first driving part 30 in the proximal direction to push the medical device 800 accommodated in the accommodating part 250 towards the host.

[0101] In some other examples, as described above, the auxiliary device 1000 may also not include the first driving part 30. In this case, after the moving body 200 is released, the moving body 200 can also be pushed towards the host by manpower, so as to push the medical device 800 accommodated in the accommodating part 250 towards the host.

[0102] In some examples, the moving body 200 may include a first bottom 210, a second bottom 220, and a side wall 230 connecting the first bottom 210 and the second bottom 220 (see Figure 7A ). The first bottom 210 may be close to the distal end, the second bottom 220 may be close to the proximal end, and the accommodating part 250 may be provided on the second bottom 220.

[0103] In some examples, a hollow part may be formed between the first bottom 210, the second bottom 220, and the side wall 230. In some examples, the puncturing member 260 may be releasably disposed in the hollow part of the moving body 200. In some examples, when the puncturing member 260 is released, it can move along the hollow part of the moving body 200. In this case, the hollow part is formed by the first bottom 210, the second bottom 220, and the side wall 230, the accommodating part 250 is provided on the second bottom 220, and the puncturing member 260 is provided in the hollow part, so that it is convenient for the puncturing member 260 to move relative to the accommodating part 250 when it is released. Thus, when the medical device 800 is applied to the host, the puncturing member 260 is released and moves relative to the accommodating part 250, so that the puncturing member 260 can leave the host.

[0104] In some other examples, the puncturing member 260 may also be fixedly disposed on the moving body 200. In this case, when the medical device 800 is applied to the host, the moving body 200 can be entirely removed from the host by manpower, and thus the puncturing member 260 can also leave the host.

[0105] In some examples, the first driving mechanism 30 may be disposed between the first bottom 210 and the first housing 100. In some examples, a positioning part 212 for positioning the first driving mechanism 30 may be provided on the first bottom 210 (see Figure 7A ). In this case, the positioning part 212 can more stably define the position where the first driving mechanism 30 acts on the moving body 200.

[0106] In some examples, the positioning portion 212 of the first bottom 210 may be a columnar protrusion protruding from the first bottom 210 along the central axis CA toward the distal end (see Figure 7A ). In some examples, the positioning portion 212 may be cylindrical. In some examples, the positioning portion 212 may be a solid cylinder, and the first driving mechanism 30 may be sleeved on the outer periphery of the positioning portion 212. In other examples, the positioning portion 212 may be a hollow cylinder, and the first driving mechanism 30 may be sleeved on the outer periphery of the positioning portion 212 or embedded in the inner periphery of the positioning portion 212.

[0107] In some examples, the first driving mechanism 30 may have an energy storage state and an energy release state. When the first driving mechanism 30 switches from the energy storage state to the energy release state, the first driving mechanism 30 may release energy and act on the moving body 200 in a proximal direction. When the moving body 200 is held, the first driving mechanism 30 may exist in the energy storage state between the moving body 200 and the first housing 100. When the moving body 200 is released, the first driving mechanism 30 may switch from the energy storage state to the energy release state and act on the moving body 200 in a proximal direction.

[0108] In some examples, the first driving mechanism 30 may have a compressed state and an extended state. When the first driving mechanism 30 switches from the compressed state to the extended state, the first driving mechanism 30 may release energy. In some examples, the first driving mechanism 30 may be a compressible elastic member. In some examples, the first driving mechanism 30 may be a spring. In some examples, one end of the first driving mechanism 30 may be sleeved on the positioning portion 212 of the first bottom 210.

[0109] In some examples, the end portion 120 may have a positioning portion 122 (see Figure 6B ). In some examples, the positioning portion 122 may be cylindrical. In this case, the other end of the first driving mechanism 30 may be sleeved on the positioning portion 122. In some examples, the positioning portion 122 may be a hollow cylinder. In this case, the other end of the first driving mechanism 30 may be sleeved on or embedded in the positioning portion 122. In some examples, the positioning portion 122 may be composed of at least two arc-shaped columns. For example, in the embodiment shown in Figure 6B , the positioning portion 122 may include an arc-shaped column 122a and an arc-shaped column 122b. In this case, the other end of the first driving mechanism 30 may be embedded between the arc-shaped column 122a and the arc-shaped column 122b.

[0110] In addition, the auxiliary device 1000 of the present embodiment is not limited thereto. In some examples, the auxiliary device 1000 may also not include the first driving mechanism 30. In this case, when the moving body 200 is released, the moving body 200 can also be moved toward the proximal end by manually applying an action to the moving body 200.

[0111] In some examples, the moving body 200 may include a first locking portion 236 configured to releasably interlock with the first holding portion 130. Thus, the moving body 200 can be releasably held by the first holding portion 130 through the cooperation of the first locking portion 236 and the first holding portion 130.

[0112] In some examples, the first locking portion 236 may be provided on the side wall 230 of the moving body 200. That is, the first locking portion 236 may be provided on the side wall 230 of the moving body 200 (see Figure 7A ). The first locking portion 236 can cooperate with the first holding portion 130 to hold the moving body 200 in the first housing 100.

[0113] In some examples, the number of the first locking portions 236 may be one or more, such as 1, 2, 3, or 4. In some examples, the number of the first locking portions 236 may be the same as the number of the first holding portions 130. In Figure 7A the illustrated embodiment, the number of the first locking portions 236 is 2, and the first locking portion 236 may include a first locking portion 236a and a first locking portion 236b.

[0114] In some examples, the first locking portion 236 may be formed into a buckle structure. Specifically, the first locking portion 236 may have a surface facing the proximal end, and the first holding portion 130 can hold the moving body 200 by lapping, abutting, or engaging with this surface, and the first holding portion 130 can release the moving body 200 by leaving this surface. That is to say, the first holding portion 130 and the first locking portion 236 can be formed into an interlocking structure. In the direction along the central axis CA, the projections of the first holding portion 130 and the first locking portion 236 have an overlapping part, and the first holding portion 130 holds the first locking portion 236 through this overlapping part, and the first holding portion 130 and / or the first locking portion 236 can move away from each other to eliminate this overlapping part, so that the first holding portion 130 releases the first locking portion 236. In some examples, the first holding portion 130 and / or the first locking portion 236 can be actuated in a manner of moving away from each other, so that the first locking portion 236 is released by the first holding portion 130.

[0115] In some examples, the first locking portion 236 may be substantially parallel to the central axis CA or away from the central axis CA in the proximal-to-distal direction. In this case, the first locking portion 236 may be closer to the central axis CA than the first holding portion 130, whereby it is possible to facilitate cooperation with the inwardly converging first holding portion 130 for interlocking.

[0116] In other examples, the first locking portion 236 may be substantially parallel to the central axis CA or move closer to the central axis CA in the proximal-to-distal direction. In this case, the first locking portion 236 may be farther from the central axis CA than the first holding portion 130, whereby it is possible to facilitate cooperation with the outwardly diverging first holding portion 130 for interlocking.

[0117] In some examples, the first locking portion 236 may be formed in such a way, for example, by being concave inward from the outer surface of the side wall 230 towards the central axis CA. In some examples, the first locking portion 236 may be formed as a hollow structure, such as a through hole passing through the side wall 230 along a direction substantially orthogonal to the central axis CA. In some examples, the first locking portion 236 may also be formed in such a way that the periphery of the first bottom portion 210 protrudes from the side wall 230 in a direction orthogonal to the central axis CA. In this case, the first bottom portion 210 and the side wall 230 may be fixedly connected. In other examples, the first locking portion 236 may also be in an inverted hook shape or an L shape.

[0118] The examples of this embodiment are not limited to this. As described above, the concept of the present disclosure is to form a buckle, hook, latch, or pin structure between the first holding portion 130 and the first locking portion 236 for interlocking. In this case, the first locking portion 236 may have a surface facing the proximal end of the auxiliary device 1000, and by engaging the surface of the first locking portion 236 facing the proximal end with the surface of the first holding portion 130 facing the distal end, the first holding portion 130 holds the first locking portion 236, and by separating the surface of the first locking portion 236 facing the proximal end from the surface of the first holding portion 130 facing the distal end, the first holding portion 130 releases the first locking portion 236.

[0119] See Figure 7B and Figure 7C , in Figure 7B and Figure 7C In the embodiments shown, the first holding portion 130 may be formed in an L shape, and the first locking portion 236 is formed as a hollow structure provided on the side wall 230. When the moving body 200 is held, that is, as Figure 7BAs shown, the protrusion 134 of the first holding portion 130 is located within the hollow structure of the first locking portion 236, thereby supporting the moving body 200 to hold the moving body 200. When the moving body 200 is released, that is, as Figure 9C shown, the arm 132 of the first holding portion 130 pivots in a direction away from the central axis CA and moves the protrusion 134 away from the central axis CA. The protrusion 134 leaves the hollow structure of the first locking portion 236, thereby releasing the moving body 200. Under the action of the first driving mechanism 30, the moving body 200 moves toward the proximal end.

[0120] In addition, referring to Figure 7B and Figure 7C , in the embodiments shown in Figure 7B and Figure 7C , the arm 132 of the first holding portion 130 can approach the central axis CA in the direction from the distal end to the proximal end. In this case, by actuating the arm 132 of the first holding portion 130 in the direction of the central axis CA, the arm 132 can be pivoted, and the protrusion 134 can be moved away from the central axis CA. The protrusion 134 leaves the hollow structure of the first locking portion 236, thereby releasing the moving body 200.

[0121] In addition, in some examples, the auxiliary device 1000 may further include a first trigger mechanism 50 configured to separate the first holding portion 130 from the first locking portion 236 to release the moving body 200 (see Figure 5B ). Thus, the moving body 200 can be conveniently released by the first trigger mechanism 50.

[0122] In some examples, the auxiliary device 1000 may further include a first trigger mechanism 50 (see Figure 5B ). The first trigger mechanism 50 is configured to trigger the first holding portion 130 so that the moving body 200 is released by the first holding portion 130. In some examples, the first trigger mechanism 50 may be configured to actuate the first holding portion 130 and / or the first locking portion 236 away from each other to release the moving body 200. For example, the first trigger mechanism 50 may be configured to actuate the first holding portion 130 to move away from the central axis CA to release the holding of the first locking portion 236, thereby releasing the moving body 200. That is, the first trigger mechanism 50 may be configured to actuate the first holding portion 130 and / or the first locking portion 236 so that the two are separated from each other to release the first locking portion 236.

[0124] In some examples, the first trigger mechanism 50 may include a pressing portion 502, an actuating portion 504, and an assembling portion 506 (see Figure 8A ). The first trigger mechanism 50 can be assembled to the end portion 120 through the assembling portion 506. By applying an action to the pressing portion 502, the actuating portion 504 can actuate the first holding portion 130, so that the first holding portion 130 releases the holding of the moving body 200 to release the moving body 200. In some examples, the pressing portion 502 may be generally in the shape of a round cake.

[0125] In some examples, the actuating portion 504 of the first trigger mechanism 50 may extend generally along the direction of the central axis CA. In some examples, the first trigger mechanism 50 is configured to be movable along the direction of the central axis CA. In this case, by driving the actuating portion 504 of the first trigger mechanism 50 along the central axis CA of the auxiliary device 1000, the first holding portion 130 can be actuated to separate from the first locking portion 236 in a simple and convenient manner.

[0126] In some examples, when projected along the direction of the central axis CA, the actuating portion 504 of the first trigger portion 50 and the first holding portion 130 may at least partially overlap (for example, at least partially overlap with the arm 132 of the first holding portion 130). When the first trigger portion 50 moves along the direction of the central axis CA, the first holding portion 130 can be actuated to move away from the first locking portion 236. Thus, the first holding portion 130 can release the first locking portion 236 through a simple operation.

[0127] In some other examples, when projecting in the direction along the central axis CA, the actuating part 504 of the first triggering part 50 and the first locking part 236 can at least partially overlap. When the first triggering part 50 moves in the direction along the central axis CA, the first locking part 236 can be actuated to move away from the first holding part 130. Thus, the first locking part 236 can be released simply and conveniently.

[0128] In some examples, the number of the assembling parts 506 can be one or more, such as 1, 2, 3, or 4. In Figure 8E the illustrated embodiment, the assembling parts 506 can be the assembling part 506a and the assembling part 506b. In some examples, multiple assembling parts 506 can be symmetrically distributed on the outer periphery of the central axis CA. In Figure 8E the illustrated embodiment, the assembling part 506a and the assembling part 506b are symmetrically distributed on both sides of the central axis CA. In some examples, the assembling parts 506 can be formed on the periphery of the pressing part 502.

[0129] In some examples, the assembling parts 506 can extend proximally from the pressing part 502 generally along the direction of the central axis CA. In some examples, the assembling parts 506 can have an arm 512 generally along the direction of the central axis CA and a protrusion 514 protruding from the arm 512 toward the central axis CA along a direction generally orthogonal to the central axis CA (see Figure 8E ). In some examples, the arm 512 of the assembling part 506 can extend proximally from the pressing part 502 generally along the central axis CA.

[0130] In some examples, the arm 512 of the assembling part 506 can be elastic. In some examples, the arm 512 of the assembling part 506 can tend to contract toward the central axis CA in the direction from the distal end to the proximal end. That is, in the natural state (i.e., the state without external force), compared between the end of the arm 512 near the proximal end and the end of the arm 512 near the distal end, the distance between the end of the arm 512 near the proximal end and the central axis CA is closer. In some other examples, the arm 512 can also be generally parallel to the central axis CA. In some examples, when an action is applied to the arm 512 along a direction generally orthogonal to the central axis CA, the arm 512 can pivot. For example, when an action is applied to the arm 512 along a direction generally orthogonal to the central axis CA in a manner toward the central axis CA, the arm 512 can pivot so that the end of the arm 512 near the proximal end moves away from the central axis CA.

[0131] In some examples, the protrusion 514 of the assembly portion 506 may have a surface facing the distal end. In some examples, the surface of the protrusion 514 facing the distal end may be substantially orthogonal to the central axis CA. A component cooperating with the assembly portion 506 (such as the biasing portion 124 and the engaging portion 126 of the end portion 120 to be described next) may be assembled and combined with the assembly portion 506 by lapping / butting against the surface of the protrusion 514 facing the distal end.

[0132] That is to say, the assembly portion 506 may be a buckle or a latch structure formed on the first trigger mechanism 50. For example, the assembly portion 506 may be formed into a structure such as a finger shape, a straight shape, an L shape, a J shape, a Z shape, etc. that can be at least decomposed into two parts. At least a part thereof (for example, the arm 512 connected to the pressing portion 502) may pivot, and the other part (for example, the protrusion 514 protruding outward from the arm 512 and abutting against the assembly and mating component) may be assembled and combined with the assembly and mating component (for example, the biasing portion 124 and the engaging portion 126 of the end portion 120 to be described next) as it pivots, such as being hooked, hung, latched, topped, supported, etc.

[0133] In some examples, the end portion 120 may include a biasing portion 124 and an engaging portion 126 (see Figure 8B and Figure 8C ). In some examples, there may be a gap between the biasing portion 124 and the engaging portion 126. In this case, the assembly portion 506 may enter the assembly position via the gap between the biasing portion 124 and the engaging portion 126. In some examples, the number of the biasing portion 124 and the engaging portion 126 of the end portion 120 may be multiple, such as 1, 2, 3, or 4. In some examples, the number of the biasing portion 124 and the number of the engaging portion 126 of the end portion 120 may be the same as the number of the assembly portions 506. In the Figure 8B and Figure 8C illustrated embodiment, the biasing portion 124 may be the biasing portion 124a and the biasing portion 124b, and the engaging portion 126 may be 126a and 126b.

[0134] In some examples, the distance between the biasing portion 124 and the central axis CA may be greater than the distance between the engaging portion 126 and the central axis CA. In some examples, in the direction along the central axis CA and toward the proximal end, the biasing portion 124 may gradually approach the central axis CA. In some examples, when projected in the direction along the central axis CA, the end of the biasing portion 124 close to the proximal end may be in contact with or slightly overlap the engaging portion 126.

[0135] Now, please refer to Figure 8G and Figure 8H, further illustrate the assembly combination of the assembly part 506 with the offset part 124 and the joint part 126. Before the assembly combination, in a direction substantially orthogonal to the central axis CA, the distance between the protrusions of the assembly part 506a and the protrusions of the assembly part 506b can be slightly less than or substantially equal to the distance between the joint part 126a and the joint part 126b (see Figure 8G ). After the assembly combination, that is, when moving the assembly part 506 along the central axis CA towards the proximal end, the assembly part 506 can pass through the gap between the offset part 124 and the joint part 126. The arm 512 of the assembly part 506 is squeezed by the offset part 124 towards the central axis CA, so that the distance between the protrusions of the assembly part 506a and the protrusions of the assembly part 506b gradually decreases and becomes less than the distance between the joint part 126a and the joint part 126b. In this case, under the squeezing action of the offset part 124, the surface of the protrusion 514 of the assembly part 506 facing the distal end can be engaged with the joint part 126, so that the assembly part 506 and the joint part 126 are interlocked to assemble and combine the first trigger mechanism 50 with the end part 120 (see Figure 8H ).

[0136] That is to say, the first trigger mechanism 50 and the end part 120 can be assembled and combined through a structure such as a buckle or a latch.

[0137] In addition, in some examples, the first trigger mechanism 50 may further have rib grooves 507. The end part 120 may have end ribs 128. In some examples, the depth of the rib grooves 507 can be substantially the same as the thickness of the end ribs 128, and the width of the rib grooves 507 can be substantially the same as the width of the end ribs 128. In this case, through the cooperation of the rib grooves 507 and the end ribs 128, it can provide a guiding effect on the assembly process. In addition, through the cooperation of the rib grooves 507 and the end ribs 128, it can also effectively inhibit the undesired rotation of the first trigger mechanism 50 assembled on the end part 120.

[0138] In some examples, the rib grooves 507 and the end ribs 128 can extend substantially along the direction of the central axis CA. In some examples, the number of the rib grooves 507 can be one or more, such as 1, 2, 3, or 4. For example, in Figure 8E and Figure 8F In the illustrated embodiment, the rib grooves 507 can be rib grooves 507a, rib grooves 507b, rib grooves 507c, and rib grooves 507d. Correspondingly, the number of the end ribs 128 can also be one or more, and can be the same as the number of the rib grooves 507. In Figure 8B In the illustrated embodiment, the end ribs 128 can be end ribs 128a, end ribs 128b, end ribs 128c, and end ribs 128d.

[0139] Figure 8Iis a schematic cross-sectional view before the first holding part 130 involved in the example of this embodiment is triggered by the first triggering mechanism 50; Figure 8J is a schematic cross-sectional view after the first holding part 130 involved in the example of this embodiment is triggered by the first triggering mechanism 50. It should be noted that in Figure 8I and Figure 8J mainly shows the triggering of the first holding part 130 by the first triggering mechanism 50.

[0140] In some examples, as described above, the actuating part 504 of the first triggering mechanism 50 can actuate the first holding part 130 so that the first holding part 130 releases the holding of the moving body 200, thereby releasing the moving body 200.

[0141] In some examples, the actuating part 504 can be formed as a columnar structure extending proximally along the central axis CA by the pressing part 502 (see Figure 8E ). In some examples, the number of the actuating parts 504 can be one or more, such as 1, 2, 3, or 4. In some examples, the number of the actuating parts 504 can be the same as the number of the first holding parts 130. In Figure 8E the shown embodiment, the actuating part 504 can include an actuating part 504a and an actuating part 504b.

[0142] In some examples, on the end part 120, a through structure corresponding to the first holding part 130 is formed in the direction substantially along the central axis CA (see Figure 8B , Figure 8C or Figure 8D ). In some examples, when projected in the direction along the central axis CA, the projection plane of the through structure can cover the projection plane of the actuating part 504.

[0143] Hereinafter, referring to Figure 8I and Figure 8J , the triggering of the first holding part 130 by the actuating part 504 will be described in detail. As described above, the first holding part 130 gradually converges towards the central axis CA in the direction along the central axis CA towards the proximal end. The actuating part 504 is configured to be able to actuate the first holding part 130 so that one end of the first holding part 130 close to the proximal end moves away from the central axis CA, thereby releasing the holding of the moving body 200. In some examples, in the direction substantially orthogonal to the central axis CA, the distance between the actuating part 504a and the actuating part 504b can be slightly greater than the distance between the first holding part 130a and the first holding part 130b.

[0144] Before the actuating part 504 actuates the first holding part 130, one end of the first holding part 130a and the first holding part 130b close to the proximal end are folded together to form an interlock with the first locking part 236 to hold the moving body 200 (see Figure 8I ). When the actuating part 504 actuates the first holding part 130 (for example, by pressing the pressing part 502 in the direction towards the proximal end), under the actuation of the actuating part 504, the first holding part 130a and the first holding part 130b gradually open outwards (that is, away from the central axis CA), so that the protrusion 134 of the first holding part 130 leaves the first locking part 236, thereby releasing the interlock between the first holding part 130 and the first locking part 236, and thus releasing the moving body 200 (see Figure 8J ).

[0145] In some examples, the end body 121 can be a solid structure. That is to say, the end body 121 may not have a through hole. In some examples, the end 120 may have a positioning part 122 extending from the end body 121 towards the proximal end (see Figure 6B ). In this case, one end of the first driving mechanism 30 can be sleeved on the positioning part 212 of the moving body 200, and the other end of the first driving mechanism 30 can be sleeved on the positioning part 122 of the end 120. In this way, the first driving mechanism 30 is arranged between the moving body 200 and the end 120.

[0146] In some examples, the first driving mechanism 30 can be a spring. Thus, an actuating mechanism can be provided for the moving body 200 through a simplified structural design.

[0147] In other examples, the end body 121 can also be a through structure. In some examples, the positioning part 508 of the first triggering mechanism 50 can be cylindrical. The first driving mechanism 30 can be sleeved on the positioning part 508. In some examples, the positioning part 508 of the first triggering mechanism 50 can be a hollow cylinder. The first driving mechanism 30 can be sleeved on or embedded in the positioning part 508. In some examples, the positioning part 508 can include two or more arc-shaped columns.

[0148] In some examples, an anti-misoperation mechanism 520 can be provided between the first triggering part 50 and the end 120 (see Figure 5B ). In some examples, the anti-misoperation mechanism 520 can be in the shape of a hairpin. In this case, through the hairpin-shaped anti-misoperation mechanism 520, the undesired movement of the first triggering mechanism 50 towards the proximal end can be effectively suppressed. In some examples, the anti-misoperation mechanism 520 can be arranged between the pressing part 502 of the first triggering mechanism 50 and the first housing 100.

[0149] In some examples, an elastic member, such as a spring (not shown), may also be 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. In this case, the unwanted movement of the first trigger mechanism 50 toward the proximal end can also be suppressed by the action of the spring toward the distal end. In addition, by providing the spring between the end portion 120 and the first trigger mechanism 50, it is also possible to help the first trigger mechanism 50 return to the initial state after the first holding portion 130 is triggered. In this case, after the first trigger mechanism 50 triggers the first holding portion 130, it can automatically return to the initial state, thereby helping to provide a reusable assistive device 1000.

[0150] Figure 9A is an exploded perspective view showing a first perspective of the second housing 140 and the assist mechanism 20; Figure 9B is an exploded perspective view showing a second perspective of the second housing 140 and the assist mechanism 20; Figure 9C is a cross-sectional view showing the assist mechanism 20 assembled to the second housing 140; Figure 9D is a schematic view showing the cover 190 according to the example of the present embodiment.

[0151] In some examples, the first bottom 210 and the side wall 230 of the moving body 200 may be integrally formed. In other examples, the first bottom 210 of the moving body 200 may also be detachably assembled and joined to the side wall 230.

[0152] In some examples, the first bottom 210 may have a coupling portion 214 (see Figure 9A ). In some examples, the number of the coupling portions 214 may be one or more, such as 1, 2, 3, or 4. In some examples, the side wall 230 may have a moving body restricting portion 238 (described later). The moving body restricting portion 238 may impose a restriction on the piercing member 260 disposed within the moving body 200, thereby suppressing the unwanted rotation of the piercing member 260. In some examples, the moving body restricting portion 238 may be formed as a groove and / or a ridge. In some examples, the moving body restricting portion 238 may be two side-by-side ridges and a groove located between the two ridges. The coupling portion 214 is coupled to the side wall 230 by engaging with the ends of the two ridges of the moving body restricting portion 238.

[0153] 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 communicate with each other. In some examples, the first limiting mechanism 150 and the second limiting mechanism 170 may be in a hollow columnar structure. In some examples, the first limiting mechanism 150 may releasably hold the moving body 200 and may define the moving path of the moving body 200. In some examples, the second limiting mechanism 170 may define the application position of the medical device 800.

[0154] That is to say, in the auxiliary device 1000 according to the present embodiment, the housing 10 may include a first housing 100 having a first holding portion 130 and a second housing 140 that can be assembled to the first housing 100. The second housing 140 may have a first limiting mechanism 150 and a second limiting mechanism 170 that communicate with each other. The second limiting mechanism 170 may be configured to define the application position of the medical device 800. The auxiliary mechanism 20 may be assembled to the first limiting mechanism 150 and may move along the first limiting mechanism 150 when the moving body 200 is released by the first holding portion 130. In this case, the movement of the moving body 200 is defined by the first limiting mechanism 150 of the second housing 140, and the application position of the medical device 800 is defined by the second limiting mechanism 170 of the second housing 140, whereby it is possible to more accurately apply the medical device 800 to the host.

[0155] In some examples, the first limiting mechanism 150 may have a limiting portion 151. The limiting portion 151 may apply a restriction to the moving body 200 to inhibit the moving body 200 from undergoing an undesired rotation. 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 portion 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 lengths of the ridge portion 154 and the groove 152 may be less than the height of the first limiting mechanism 150, and the ridge portion 154 and the groove 152 may be substantially collinear in the direction of the central axis CA. In some examples, the limiting portion 151 may further include a notch 156 provided on the first limiting mechanism 150. The notch 156, the ridge portion 154, and the groove 152 may be formed in sequence from the proximal end to the distal end along the same straight line. In some examples, the number of the limiting portions 151 may be one or more, such as 1, 2, 3, or 4. In some examples, a plurality of limiting portions 151 may be uniformly distributed on the side wall of the first limiting mechanism 150.

[0156] In some examples, the ridge 154 of the limiting portion 151 can cooperate with the restricted portion 232 (described later) of the moving body 200 that includes a groove structure, thereby inhibiting the undesired rotation of the moving body 200. In some examples, the moving body 200 can be assembled to the first limiting mechanism 150 along the groove 152, and thus the groove 152 can provide a guiding function during assembly. Additionally, in some examples, the notch 156 can be used to provide an engaging space for the protrusion 234 (described later) of the moving body 200.

[0157] Additionally, in some examples, the first limiting mechanism 150 can further include reinforcing ribs 158 provided on the inner wall (see Figure 9B ). In some examples, the reinforcing ribs 158 can extend substantially along the direction of the central axis CA. In some examples, the number of the reinforcing ribs 158 can be multiple, such as 2, 3, 4, 6, etc. In some examples, the reinforcing ribs 158 can be evenly distributed on the inner wall of the first limiting mechanism 150.

[0158] Additionally, in some examples, the first limiting mechanism 150 can further include protrusions 160 provided on the inner wall (specifically described later).

[0159] Additionally, in some examples, the first limiting mechanism 150 can limit the stroke of the moving body 200 in the direction along the central axis CA. In this case, by using the first limiting mechanism 150 to limit the stroke of the moving body 200 in the direction along the central axis CA, the medical device 800 accommodated in the accommodating portion 250 can be pushed a predetermined distance more accurately, and thus the medical device 800 can be applied to the host more accurately.

[0160] Additionally, in some examples, when projected in the direction along the central axis CA, the accommodating portion 250 and the wall of the first limiting mechanism 150 can at least partially overlap, and the end of the moving body 200 close to the distal end and the wall of the first limiting mechanism 150 can at least partially overlap (see Figure 9C ). In this case, by making the accommodating portion 250 and the moving body 200 at least partially overlap with the wall of the first limiting mechanism 150, the stroke of the moving body 200 moving along the first limiting mechanism 150 can be effectively limited under the condition of simplified structure.

[0161] Additionally, in some examples, a protrusion protruding away from the central axis CA in a direction substantially orthogonal to the central axis CA is provided on the end of the moving body 200 close to the distal end. In this case, by forming a snap with the wall of the first limiting mechanism 150 through this protrusion, the overtravel of the moving body 200 towards the proximal end can be effectively limited.

[0162] In addition, in some examples, the first limiting mechanism 150 can inhibit the rotation of the moving body 200. In this case, by inhibiting the rotation of the moving body 200, the puncturing member 260 can be inhibited from rotating undesirably during the application process.

[0163] In addition, in some examples, the first limiting mechanism 150 can include grooves and / or ridges disposed on the inner wall continuously or discontinuously substantially along the direction of the central axis CA. In this case, by engaging the moving body 200 with the grooves and / or ridges of the first limiting mechanism 150, the moving body 200 can be effectively inhibited from rotating undesirably within the first limiting mechanism 150.

[0164] In addition, in some examples, the moving body 200 can include grooves and / or ridges disposed on the outer wall of the side wall 230 substantially along the direction of the central axis CA. In this case, by engaging the grooves and / or ridges of the moving body 200 with the grooves and / or ridges of the first limiting mechanism 150, the moving body 200 can be effectively inhibited from rotating undesirably within the first limiting mechanism 150.

[0165] In addition, in some examples, the first limiting mechanism 150 and the second limiting mechanism 170 can be in the shape of a hollow cylinder and the inner diameter of the first limiting mechanism 150 can be not greater than the inner diameter of the second limiting mechanism 170. In this case, by setting the first limiting mechanism 150 and the second limiting mechanism 170 as hollow cylinders, the auxiliary mechanism 20 can be facilitated to move along the first limiting mechanism 150 and the second limiting mechanism 170.

[0166] In addition, in some examples, when the moving body 200 is released, the moving body 200 can move along the first limiting mechanism 150 and the accommodating portion 250 can move along the second limiting mechanism 170. In this case, by making the moving body 200 move along the first limiting mechanism 150 and the accommodating portion 250 move along the second limiting mechanism 170, the medical device 800 accommodated in the accommodating portion 250 can be applied to the desired position on the body surface of the host more accurately.

[0167] In some examples, a restricted portion 232 can be provided on the side wall 230 of the moving body 200 (see Figure 9A and Figure 9B)。The limiting part 232 can cooperate with the limiting part 151 of the first limiting mechanism 150 to inhibit the unwanted rotation of the moving body 200. In some examples, the limiting part 232 can include a groove 235 formed on the outer wall of the side wall 230. In some examples, the groove 235 can be formed between two side-by-side ridges. In some examples, the limiting part 232 can further include an arm 233 formed by the side wall 230 extending towards the distal end along the direction of the groove 235. In some examples, the limiting part 232 can further include a protrusion 234 protruding away from the central axis by the arm 233 along a direction substantially orthogonal to the central axis CA. In some examples, the number of the limiting parts 232 can be one or more, such as 1, 2, 3, or 4. In some examples, the number of the limiting parts 232 can be the same as the number of the limiting parts 151. In some examples, multiple limiting parts 232 can be evenly distributed on the side wall 230. In some examples, the arm 233 can be elastic.

[0168] In some examples, when projected along a direction substantially orthogonal to the central axis CA, the projection surface of the protrusion 234 of the limiting part 232 can be further away from the central axis CA than the projection of the notch 156 of the limiting part 151. Additionally, the projection of the ridge 154 and the projection of the groove 235 can be substantially engaged. Additionally, the projection of the protrusion 234 and the projection of the groove 152 can be substantially engaged. In some examples, the length and / or width of the accommodating part 250 can be greater than the diameter of the first limiting mechanism 150.

[0169] Hereinafter, with reference to Figure 9C , an action is applied along the direction of the central axis CA towards the moving body 200, so that the moving body 200 is assembled to the first limiting mechanism 150 via the second limiting mechanism 170. The protrusion 234 can slide into the groove 152, thereby providing a mechanism for guiding the assembly. When the protrusion 234 abuts against the ridge 154, the ridge 154 squeezes the protrusion 234 and causes the arm 233 to elastically deform, so that the protrusion 234 is moved towards the central axis CA and can continue to slide past the ridge 154. When the protrusion 234 protrudes towards the distal end in the direction of the central axis CA from the first limiting mechanism 150, the arm 233 returns to its initial state, so that the protrusion 234 protrudes from the first limiting mechanism 150 in a direction substantially orthogonal to the central axis CA.

[0170] The moving body 200 assembled and combined with the first limiting mechanism 150. The groove 235 of the moving body 200 can engage with the ridge 154 of the first limiting mechanism 150. Thus, when the moving body 200 moves along the first limiting mechanism 150, it can be limited in the direction in which the ridge 154 extends. In addition, through the engagement of the groove 235 and the ridge 154, a mechanism for suppressing rotation can also be provided to suppress the undesired rotation of the moving body 200 within the first limiting mechanism 150. In this case, when the puncturing mechanism 260 pierces into the subcutaneous tissue of the host along with the moving body 200, since the undesired rotation is effectively suppressed, the discomfort caused to the host during the application process can be reduced.

[0171] In addition, as described above, when projected in the 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 moving body 200 is assembled and combined with the first limiting mechanism 150, a snap connection is formed by the protrusion 234 and the notch 156, thereby being able to limit the displacement amount of the moving body 200 traveling toward the proximal end.

[0172] In addition, as described above, in the direction substantially orthogonal to the central axis CA, the length and / or width of the accommodating portion 250 connected to the second bottom 220 of the moving body 200 is greater than the diameter of the first limiting mechanism 150. In this case, when the moving body 200 is assembled and combined with the first limiting mechanism 150, the displacement amount of the moving body 200 traveling toward the distal end can be limited by the accommodating portion 250.

[0173] In some examples, the second limiting mechanism 170 may include an upper bottom 172, a lower bottom 176, and a side portion 174 connecting the upper bottom 172 and the lower bottom 176 (see Figure 9B ). In some examples, the upper bottom 172 may be formed in such a way that it extends outward from the proximal end of the first limiting mechanism 150 in a direction substantially orthogonal to the central axis CA. The side portion 174 may be in the shape of a hollow cylindrical structure, and the extending direction of the side portion 174 may be substantially parallel to the central axis CA. The lower bottom 176 may be formed in such a way that it extends outward from the proximal end of the side portion 174 in a direction substantially orthogonal to the central axis CA.

[0174] In some examples, the width by which the lower bottom 176 protrudes in a direction substantially orthogonal to the central axis CA from the side portion 174 may be substantially equal to the thickness of the peripheral portion 110 of the first housing 100.

[0175] In some examples, the second limiting mechanism 170 may include a rib groove 178 provided on the side portion 174 (see Figure 9B)。In some examples, the number of rib grooves 178 can be one or more, such as 1, 2, 3, or 4. In some examples, the rib grooves 178 can be formed in such a way that two ridges extending generally along the direction of the central axis CA are arranged side by side on the side portion 174, and the rib grooves 178 can be formed between these two side-by-side ridges.

[0176] In some examples, the rib grooves 178 can cooperate with the peripheral ribs 112 of the peripheral portion 110 to assemble and couple the first housing 100 and the second housing 140. In some examples, the number of rib grooves 178 can be the same as the number of peripheral ribs 112. In some examples, the peripheral ribs 112 can be assembled into the rib grooves 178 in an inserted manner generally 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 defining mechanism 170. When the first housing 100 and the second housing 140 are moved towards each other generally along the direction of the central axis CA, the peripheral ribs 112 can enter the rib grooves 178, thereby assembling and coupling the first housing 100 and the second housing 140.

[0177] In some examples, the second defining mechanism 170 may further include a fitting hole 180 provided on the upper bottom portion 172 (see Figure 9B )。In some examples, the number of fitting holes 180 can be one or more, such as 1, 2, 3, or 4. In some examples, the number of fitting holes 180 can be the same as the number of connection posts 114 of the first housing 100. The fitting holes 180 can cooperate with the connection posts 114 to assemble and couple the first housing 100 and the second housing 140. The connection posts 114 can be docked with the fitting holes 180.

[0178] In some examples, the second defining mechanism 170 may further include a flange 183 (see Figure 9B )。

[0179] In some examples, the accommodating portion 250 can move along the second defining mechanism 170. In some examples, when operating the assisting device 1000, by applying the second defining mechanism 170 to the body surface of the host, the application position of the medical device 800 can be defined thereby.

[0180] In addition, in some examples, a side portion card slot 182 is provided on the inner wall of the side portion 174 of the second defining mechanism 170 (see Figure 9A)。In some examples, the number of the side slots 182 may be multiple, such as 1, 2, 3, or 4. In some examples, the multiple side slots 182 may be evenly distributed on the inner wall of the side portion 174. In some examples, the side slots 182 may extend substantially along the direction of the central axis CA. The side slots 182 may cooperate with the lid engaging portion 194 (described later) of the lid 190 to assemble and couple the second housing 140 with the lid 190.

[0181] In some examples, the housing 10 may further include a lid 190 detachably covering the second housing 140 (see Figure 5B ).

[0182] In some examples, the lid 190 may include a lid bottom 192 and a lid engaging portion 194 provided on the lid bottom 192 (see Figure 9D ). The lid engaging portion 194 may cooperate with the side slots 182 of the second housing 140 to assemble and couple the lid 190 with the second housing 140. The number of the lid engaging portions 194 may be multiple, such as 1, 2, 3, or 4. The number of the lid engaging portions 194 may be equal to the number of the side slots 182. In Figure 9D the illustrated embodiment, the lid engaging portion 194 may include a lid engaging portion 194a and a lid engaging portion 194b. The lid engaging portion 194a and the lid engaging portion 194b may be distributed on opposite sides of the lid bottom 192 along the symmetry axis of the lid 190.

[0183] In some examples, the lid engaging portion 194 may include an arm extending substantially along the central axis CA from the lid bottom 192 towards the distal end and a protrusion protruding from the end of the arm in a direction away from the central axis CA. The arm of the lid engaging portion 194 may be elastic. When the lid 190 is assembled and coupled with the second housing 140, the protrusion of the lid engaging portion 194 may be snapped into the side slots 182 of the second housing 140.

[0184] In some examples, the lid 190 may further include a lid support 196 (see Figure 9D ). The axis of the lid support 196 may be substantially parallel to the central axis CA. In some examples, the lid support 196 may be formed by the lid bottom 192 extending towards the distal end along the central axis CA. In some examples, when the moving body 200 is held, the vertical distance between the surface of the medical device 800 facing the proximal end in the accommodating portion 250 and the lower bottom 176 of the second housing 140 may be substantially equal to the height of the lid support 196. In this case, when the lid 190 is assembled and coupled with the second housing 140, the medical device 800 accommodated in the accommodating portion 250 is supported by the lid support 196, thereby being able to further inhibit the unexpected release of the moving body 200 due to, for example, misoperation.

[0185] In some examples, the lid 190 may further include a flange 198 (see Figure 9D ). The position of the flange 198 of the lid 190 may correspond to the flange 183 of the second housing 140. Specifically, when the lid 190 is assembled and combined with the second housing 140 and projected in the direction along the central axis CA, the projection surface of the flange 198 and the projection surface of the flange 183 may substantially coincide, or the projection surface of the flange 198 may substantially cover the projection surface of the flange 183.

[0186] Figure 10A is an exploded schematic view showing a first perspective of the moving body 200 and the puncturing member 260 involved in the example of this embodiment; Figure 10B is an exploded schematic view showing a second perspective of the moving body 200 and the puncturing member 260 involved in the example of this embodiment; Figure 10C is a cross-sectional schematic view showing the puncturing member 260 being held in the example of this embodiment; Figure 10D is a cross-sectional schematic view showing the puncturing member 260 being released in the example of this embodiment; Figure 10E is a cross-sectional schematic view showing the pre-assembly of the moving body 200 and the puncturing member 260 in the example of this embodiment.

[0187] In some examples, the moving body 200 and the puncturing member 260 may be integrally and fixedly connected. In other examples, the moving body 200 and the puncturing member 260 may be detachably assembled and combined. In some examples, the puncturing member 260 may be releasably held by the moving body 200.

[0188] In some examples, the moving body 200 may have a first bottom 210 near the distal end, a second bottom 220 near the proximal end, and a side wall 230 connecting the first bottom 210 and the second bottom 220. In some examples, a hollow portion may be formed between the first bottom 210, the second bottom 220, and the side wall 230. In some examples, the accommodating portion 250 may be provided on the second bottom 220 and face the proximal end. In some examples, the puncturing member 260 may be provided in the hollow portion. In some examples, the second bottom 220 may have a through hole 226. Additionally, in some examples, the puncturing member 260 may pass through the through hole 226.

[0189] In some examples, the puncturing member 260 can be releasably disposed within the hollow portion. Additionally, the puncturing member 260 can be configured to move within the hollow portion relative to the moving body 200 when released. In some examples, a second driving mechanism 40 can be provided between the second bottom 220 of the moving body 200 and the puncturing member 260. The second driving mechanism 40 is configured to act on the puncturing member 260 towards the distal end. When the puncturing member 260 is released, the second driving mechanism 40 can act on the puncturing member 260 towards the distal end to cause the puncturing member 260 to separate from the host. In some examples, the second driving mechanism 40 can be disposed between the support seat 280 of the puncturing member 260 and the second bottom 220 of the moving body 200. Thereby, it is beneficial for the second driving mechanism 40 to act on the puncturing member 260 to move away from the receiving portion 250.

[0190] In some examples, as described above, the moving body 200 can include a side wall 230 (see Figure 10A and Figure 10B ). In some examples, the moving body 200 can include a limiting portion 238 provided on the side wall 230. The puncturing member 260 can have a limited portion 285 (described later). When the puncturing member 260 is assembled and combined with the moving body 200, the moving body 200 can impose a limit on the limited portion 285 through the limiting portion 238 to limit the movement of the puncturing member 260. In some examples, the number of the limiting portions 238 can be one or more, such as 1, 2, 3, or 4. In some examples, a plurality of limiting portions 238 can be evenly distributed on the inner wall of the side wall 230.

[0191] In some examples, the moving body 200 can further include a second holding portion 242 (see Figure 10A and Figure 10B ). The puncturing member 260 can have a second locking portion 286. When the puncturing member 260 is assembled and combined with the moving body 200, the moving body 200 can interlock with the puncturing member 260 through the second holding portion 242 to hold the puncturing member 260. In some examples, the holding of the puncturing member 260 by the second holding portion 242 can be a releasable holding. In some examples, the number of the second holding portions 242 can be one or more, such as 1, 2, 3, or 4. In one example, a plurality of second holding portions 242 can be evenly distributed on the side wall 230.

[0192] Additionally, in some examples, the moving body 200 can be configured to inhibit the rotation of the puncturing member 260. In this case, by inhibiting the undesired rotation of the puncturing member 260 during the application process, the user experience during the application of the medical device 800 can be improved. In some examples, the moving body 200 can inhibit the undesired rotation of the puncturing member 260 during the application process through the limiting portion 238.

[0193] Additionally, in some examples, the moving body 200 can include grooves and / or ridges disposed on the inner wall of the side wall 230 generally along the direction of the central axis CA. In this case, by the cooperation of the grooves and / or ridges disposed on the inner wall of the side wall of the moving body 200 with the grooves and / or ridges of the puncturing member 260, the undesired rotation of the puncturing member 260 during the application process can be effectively inhibited. That is, in some examples, the limiting portion 238 of the moving body 200 can be grooves and / or ridges disposed on the inner wall of the side wall 230 generally along the direction of the central axis CA.

[0194] In some examples, the limiting portion 238 of the moving body 200 can be formed as a groove structure (see Figure 10A and Figure 10B ). In some examples, the limiting portion 238 can include two ridges disposed side by side on the inner wall of the side wall 230 generally along the direction of the central axis CA, and a groove formed between the two ridges.

[0195] Additionally, in some examples, the moving body 200 can have a notch 242 generally along the direction of the central axis CA. In this case, by providing the notch 242 along the direction of the central axis CA on the moving body 200, it is possible to facilitate the action on the puncturing member 260 disposed in the hollow portion of the moving body 200.

[0196] Additionally, in some examples, a protrusion 160 that can protrude toward the central axis CA via the notch 242 can be provided on the inner wall of the first limiting mechanism 150. In this case, when the moving 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 via the notch 242 of the moving body 200, thereby providing a triggering mechanism for the puncturing member 260 with a simplified structure.

[0197] In some examples, the second holding portion 242 of the moving body 200 can be a notch formed on the side wall 230 (see Figure 10A and Figure 10B)。In some examples, the second retaining portion 242 may extend generally along the central axis CA and have a first incision 244 and a second incision 246 that communicate with each other. The first incision 244 may be near the proximal end, and the second incision 246 may be near the distal end. In some examples, the widths of the first incision 244 and the second incision 246 may be different. In some examples, the width of the first incision 244 may be greater than the width of the second incision 246.

[0198] In some examples, the receiving portion 250 may have a restraining portion 252 for restraining the application portion 860. In this case, the application portion 860 of the medical device 800 received in the receiving portion 250 is restrained by the restraining portion 252, whereby the medical device 800 can be received more firmly.

[0199] In some examples, the restraining portion 252 of the receiving portion 250 may include an arm 254 and a protrusion 256. The arm 254 may extend outward from the bottom of the receiving portion 250 in a direction generally the same as the side portion. In some examples, the arm 254 and the side portion of the receiving portion 250 may be generally in the same circumferential direction. In some examples, the arm 254 may be elastic. In some examples, the arm 254 may converge 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 received in the receiving portion 250, whereby the medical device 800 can be received more firmly.

[0200] In some examples, the number of the restraining portions 252 may be one or more, such as 1, 2, 3, or 4. In some examples, the restraining portions 252 may be uniformly distributed along the side portion of the receiving portion 250.

[0201] In some examples, the puncturing member 260 may include a sharp object 270 and a support seat 280 for supporting the sharp object 270 (see Figure 10A and Figure 10B ). In some examples, the support seat 280 of the puncturing member 260 may be disposed in the hollow portion of the moving body 200, the receiving portion 250 may be disposed on the second bottom 220, the second bottom 220 may have a through hole 226, and the sharp object 270 may pass through the through hole 226 of the second bottom 220. In this case, by arranging the sharp object 270 to pass through the through hole 226 of the second bottom 220, the sharp object 270 can be engaged with the medical device 800 received in the receiving portion 250, whereby it is possible to facilitate placing at least a part of the medical device 800 under the skin of the host through the puncturing member 260.

[0202] In addition, in some examples, the moving body 200 may further include a structure 224 disposed on the second bottom 220 for positioning the second driving mechanism 40 (see Figure 10C ). In some examples, 224 may be columnar. In some examples, 224 may be a hollow cylindrical shape. In this case, the second driving mechanism 40 can be positioned by being sleeved on 224, thereby being able to define the driving position of the second driving mechanism 40.

[0203] In addition, in some examples, when the puncturing member 260 is held, the distance between the support seat 280 and the first bottom 210 may be not less than the length by which the sharp object 270 protrudes from the accommodating portion 250. In this case, by setting the distance between the support seat 280 and the first bottom 210 to be not less than the length by which the sharp object 270 protrudes from the accommodating portion 250, a moving space can be provided for the puncturing member 260 to leave the host, thereby being able to reduce the undesired injury to the host caused by the puncturing member 260.

[0204] In some examples, the sharp object 270 and the support seat 280 may be integrally formed. In other examples, the sharp object 270 and the support seat 280 may be configured to be detachably assembled and combined. Thereby, it is possible to facilitate the separate sterilization of the sharp object 270.

[0205] In some examples, the restricted portion 285 of the puncturing member 260 may be formed as a ridge structure (see Figure 10B ). In some examples, the restricted portion 285 may include two grooves arranged side by side on the side wall of the support seat 280 substantially along the direction of the central axis CA, and a ridge formed between the two grooves. In some examples, the number of the restricted portions 285 may be one or more, such as 1, 2, 3, or 4. In some examples, the number of the restricted portions 285 may be equal to the number of the restricting portions 238.

[0206] In addition, in some examples, the support seat 280 may include grooves and / or ridges arranged on the outer wall substantially along the direction of the central axis CA. In this case, by the cooperation of the grooves and / or ridges of the support seat 280 with the grooves and / or ridges on the inner wall of the side wall of the moving body 200, the undesired rotation of the puncturing member 260 can be effectively inhibited. That is to say, the restricted portion 285 of the puncturing member 260 may be formed as grooves and / or ridges arranged on the outer wall substantially along the direction of the central axis CA. The restricted portion 285 of the puncturing member 260 may cooperate with the restricting portion 238 of the moving body 200 to inhibit the undesired rotation of the puncturing member 260.

[0207] Additionally, in some examples, the piercing member 260 may include a second locking portion 286 configured to releasably interlock with the second retaining portion 242. Thus, the piercing member 260 can be releasably retained in the second retaining portion 242 by the engagement of the second locking portion 286 with the second retaining portion 242. In some examples, the second locking portion 286 may be disposed on the support base 280 of the piercing member 260.

[0208] In some examples, second locking portion 286 may include an arm 287 extending generally along central axis CA, and a protrusion 288 that cooperates with arm 287 and protrudes away from central axis CA in a direction generally perpendicular to central axis CA. In this case, when piercing member 260 is placed within the hollow portion of moving body 200, second locking portion 286 overlaps cutout 242 of moving body 200, thereby retaining piercing member 260 while simplifying the structure. In some examples, arm 287 of second locking portion 286 may be elastic in a direction generally perpendicular to central axis CA of assistive device 1000.

[0209] That is, in some examples, the movable body 200 may have a cutout 242 substantially along the direction of the central axis CA. In some examples, when the piercing member 260 is retained, the protrusion 288 of the second locking portion 286 may pass through the cutout 242. In this case, by overlapping the protrusion 288 of the second locking portion 286 with the cutout 242 of the movable body 200, the second locking portion 286 can be retained with a simplified structure.

[0210] Additionally, in some examples, when the piercing member 260 is released, the arm 288 of the second locking portion 286 may be pressed toward the central axis CA, thereby enabling the second locking portion 286 to be released with ease.

[0211] Additionally, in some examples, the second retaining portion 242 and the second locking portion 286 can be releasably interlocked by at least one of a snap, a hook, a latch, or a pin. In this case, the second retaining portion 242 and the second locking portion 286 can be releasably interlocked by at least one of a snap, a hook, a latch, or a pin, thereby providing an interlocking method that is easy to release.

[0212] In some examples, the second locking portion 286 of the piercing member 260 can be formed as a shoulder structure (see Figure 10A and Figure 10B)。In some examples, the second locking portion 286 may include an arm 287 extending generally in the direction of the central axis CA towards the distal end, and a protrusion 288 protruding from the end of the arm 287 in a direction generally orthogonal to the central axis CA and away from the central axis CA. In some examples, the arm 287 may be elastic. In some examples, along the direction of the central axis CA and towards the distal end, the arm 287 may gradually move away from the central axis CA. In some examples, when projected along the direction of the central axis CA, the projection surface of the protrusion 288 may coincide entirely or partially with the projection surface of the first notch 244. In some examples, the number of the second locking portions 286 may be one or more, such as 1, 2, 3, or 4. In some examples, the number of the second locking portions 286 may be equal to the number of the second holding portions 242.

[0213] In addition, in some examples, the width of the surface of the protrusion 288 facing the distal end may be smaller than the width of the first notch 244 and may be larger than the width of the second notch 246.

[0214] In some examples, when assembling the first limiting mechanism 150 and the moving body 200, the protrusion 160 provided on the inner wall of the first limiting mechanism 150 may sequentially pass through the second notch 246 and the first notch 244. In this case, by providing the first notch 244, a holding mechanism for the puncturing member 260 can be provided. In addition, by providing the second notch 246, a structure conducive to assembly can be provided. 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. In addition, the protrusion 160 can pass through the first notch 244 and abut against the protrusion 288 of the second locking portion 286. Thus, through the protrusion 160 and the first notch 244, a triggering mechanism for releasing the second locking portion 286 can also be provided.

[0215] See Figure 10E , by applying an action to the puncturing member 260 towards the proximal end, the puncturing member 260 enters the hollow portion of the moving body 200, and the restricted portion 285 of the puncturing member 260 is aligned with the restricting portion 238 of the moving body 200 one by one, and the restricted portion 285 can be engaged in the restricting portion 238 (see Figure 10E ). Thus, on the one hand, it can provide guidance for the assembly of the puncturing member 260 and the moving body 200; on the other hand, the puncturing member 260 assembled in the moving body 200 is restricted by the restricting portion 238, and unwanted rotation can be effectively suppressed.

[0216] In addition, see Figure 10C and Figure 10D, when the protrusion 288 of the second locking portion 286 of the puncturing member 260 is moved to the first incision 244, since it is no longer pressed by the inner wall of the side wall 230, the arm 287 returns to its initial state, that is, the projection plane of the protrusion 288 along the central axis CA and the projection plane of the first incision 244 completely or partially coincide. And since the width of the surface of the protrusion 288 facing the distal end is greater than the width of the second incision 246, the protrusion 288 is placed in the first incision 244 and the surface of the protrusion 288 facing the distal end abuts against the junction of the first incision 244 and the second incision 246 (see Figure 10C ), so as to be held within the hollow portion of the moving body 200. When an action is applied to the arm 287 to pivot it in the direction of the central axis CA, the protrusion 288 moves in the direction of the central axis CA, that is, moves inwards. In this case, the surface of the protrusion 288 facing the distal end no longer abuts against the junction of the first incision 244 and the second incision 246, so that the puncturing member 260 is released by the moving body 200 (see Figure 10D ).

[0217] In some examples, after the puncturing member 260 is released by the moving body 200, the second driving mechanism 40 drives the puncturing member 260 towards the distal end so that the puncturing member 260 leaves the host.

[0218] In some examples, the second driving mechanism 40 and the first driving mechanism 30 may have the same or similar configurations. For the features of the second driving mechanism 40, please refer to the description of the features of the first driving mechanism 30. In some examples, the second driving mechanism 40 may be a spring. Thus, an actuation mechanism can be provided for the puncturing member 260 through a simplified structural design.

[0219] In some examples, the second driving mechanism 40 may be disposed between the support seat 280 and the second bottom 220, and when the puncturing member 260 is held, the distance between the support seat 280 and the first bottom 210 is not less than the depth at which the sensor 820 is implanted subcutaneously. In this case, by providing sufficient moving space for the puncturing member 260, it is thus possible to facilitate the puncturing member 260 leaving the host.

[0220] In some examples, the puncturing member 260 may have a positioning portion 289 provided on the support seat 280 (see Figure 10C or Figure 10D ). In some examples, the positioning portion 289 may be a columnar structure. One end of the second driving mechanism 40 may be sleeved on the positioning portion 289 of the puncturing member 260, and the other end of the second driving mechanism 40 may be sleeved on the positioning portion 212 of the moving body 200. In this way, the second driving mechanism 40 is disposed between the moving body 200 and the puncturing member 260.

[0221] In some examples, the auxiliary device 1000 also provides a triggering mechanism to disengage the second retaining portion 242 from interlocking with the second locking portion 286, thereby releasing the piercing member 260 from the moving body 200. That is, in some examples, the auxiliary device 1000 further includes a second triggering mechanism configured to separate the second retaining portion 242 from the second locking portion 286 to release the piercing member 260. Thus, the piercing member 260 can be conveniently released by the second triggering mechanism.

[0222] As described above, the second locking portion 286 is formed as a shoulder structure that can abut against the second retaining portion 242, and is thus held by the second retaining portion 242 in the form of a buckle. In some examples, such a triggering mechanism is provided that can actuate the second retaining portion 242 or the second locking portion 286 to separate the second retaining portion 242 from the second locking portion 286.

[0223] In some examples, the triggering mechanism acting on the second retaining portion 242 and the second locking portion 286 can be provided on the travel path of the second locking portion 286. When the moving body 200 moves toward the proximal end, this triggering mechanism can be activated. In some examples, the triggering mechanism can be a protrusion provided on the travel path of the second locking portion 286. In this case, when the second locking portion 286 passes by this protrusion, the arm 287 of the second locking portion 286 can be squeezed toward the central axis CA and elastically deformed, so that the protrusion 288 of the second locking portion 286 is separated from the first notch 244 and the second notch 246.

[0224] In some examples, as previously mentioned, a protrusion 160 is provided on the inner wall of the first limiting mechanism 150 (see Figure 9B ). 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 by this protrusion. Additionally, when the piercing member 260 is held within the hollow portion of the moving body 200, the second locking portion 286 of the piercing member 260 is squeezed by this protrusion 160 and deformed, and moves away from the junction of the first notch 244 and the second notch 246, thereby releasing the piercing member 260.

[0225] Furthermore, when assembling the moving body 200 and the first limiting mechanism 150, the protrusion 160 can pass through the second notch 246 and the first notch 244 in sequence until the moving body 200 is assembled and combined with the first limiting mechanism 150. By providing the protrusion 160 on the inner wall of the first limiting mechanism 150, and the first notch 244 and the second notch 246 on the side wall 230 of the moving body 200, a triggering mechanism during movement can be provided without adversely affecting the assembly of the moving body 200 and the first limiting mechanism 150.

[0226] In some examples, when the moving body 200 is held and the puncturing member 260 is also held, in the direction along the central axis CA of the auxiliary device 1000, the distance between the proximal - side surface of the receiving portion 250 and the proximal - side surface of the second limiting mechanism 170 is substantially equal to the distance between the protrusion 160 of the first limiting mechanism 150 and the protrusion 288 of the second locking portion 286 (i.e., the distance between the protrusion 160 of the first limiting mechanism 150 and the second notch 246). In this case, when the receiving portion 250 moves along the second limiting mechanism 170 to the body surface of the host, the puncturing member 260 can be released, so that the puncturing member 260 can be retracted at an appropriate time to leave the host.

[0227] Hereinafter, the application process of the auxiliary device 1000 will be described again: Applying the medical device 800 to the host by the auxiliary device 1000 can include an application stage and a retraction stage. In the application stage, the medical device 800 can be applied to the host; in the retraction stage, the puncturing member 260 can leave the host.

[0228] In the application stage, by pressing the pressing portion 502 of the first trigger mechanism 50, the actuating portion 504 of the first trigger mechanism 50 moves toward the proximal end; then, when the actuating portion 504 moves to the first holding mechanism 130, the actuating portion 504 actuates the first holding mechanism 130 to pivot in a direction away from the central axis CA (see Figure 8I and Figure 8J ), so that the first holding portion 130 is separated from the first locking portion 236 (see Figure 7B and Figure 7C ), thereby releasing the moving body 200; then, the first driving mechanism 30 acts on the moving body 200 in a proximal - direction manner, so that the moving body 200 moves toward the proximal end; then, under the action of the puncturing member 260, the medical device 800 accommodated in the receiving portion 250 is at least partially placed under the skin of the host.

[0229] In some examples, the auxiliary device 1000 may not include the first driving mechanism 30 either. In this case, after the moving body 200 is released, the moving body 200 can also be driven toward the host by manpower, so that the medical device 800 accommodated in the receiving portion 250 is applied to the host through the puncturing member 260.

[0230] During the retraction phase, as the moving body 200 moves proximally along the first limiting mechanism 150, the protrusion 160 provided on the inner wall of the first limiting mechanism 150 approaches the second locking portion 286 of the puncturing member 260 through the first notch 244 provided on the moving body 200, and the protrusion 160 presses against the second locking portion 286 to pivot the second locking portion 286 in a direction close to the central axis CA, so that the second locking portion 286 is separated from the second holding portion 242 (see Figure 10C and Figure 10D ); then, the second driving mechanism 40 acts on the puncturing member 260 in a distal direction, so that the puncturing member 260 moves distally and away from the host.

[0231] In some examples, the puncturing member 260 may also be fixedly connected to the moving body 200. Additionally, in some examples, the auxiliary device 1000 may not include the second driving mechanism 40. In this case, when the medical device 800 is applied to the host, the moving body 200 can be driven as a whole in a direction away from the host by means of human force, and thus the puncturing member 260 fixedly connected to the moving body 200 can follow the moving body 200 and leave the host.

[0232] In addition, it should be noted that during the retraction phase, the first driving mechanism 30 (or by means of human force) can still act on the moving body 200 towards the host. In other words, for the first driving mechanism 30 configured as an elastic member (e.g., a spring), when the moving body 200 is driven towards the host and the medical device 800 accommodated in the accommodating portion 250 is applied 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 retraction phase, the medical device 800 is closely attached to the body surface of the host under the action of the first driving mechanism 30, thereby effectively reducing the possibility of the medical device 800 detaching from the host during the retraction phase.

[0233] Figure 11A is an exploded view showing the puncturing member 260 involved in the example of the present embodiment; Figure 11B is an assembled view showing the puncturing member 260 involved in the example of the present embodiment; Figure 11C is an enlarged view showing the needle-like portion 272 involved in the example of the present embodiment.

[0234] As described above, in the present embodiment, the puncturing member 260 may include a sharp object 270 and a support seat 280 that supports the sharp object 270 (see Figure 11A)。In some examples, the sharp object 270 and the support base 280 can be integrally formed. In other examples, the sharp object 270 can be detachably assembled and coupled with the support base 280. In some examples, the sharp object 270 can have a groove, and the medical device 800 can be placed entirely or partially in the groove. In some examples, the second driving mechanism 40 can act on the support base 280. In this case, by placing the medical device 800 entirely or partially in the groove of the sharp object 270, it is possible to facilitate placing at least a part of the medical device 800 under the skin of the host through the puncturing member 260. In some examples, the implanted portion of the sensor 820 can be placed in the groove 274 of the sharp object 270.

[0235] In some examples, the sharp object 270 can include a needle-like portion 272 (see Figure 11A ). In some examples, a groove 274 extending along the length direction of the needle-like portion 272 can be provided on the needle-like portion 272. The medical device 800 can be at least partially disposed in the groove 274 of the sharp object 270. In this case, the sensor 820 can be received in the groove 274 to facilitate placing the sensor 820 under the skin of the host following the sharp object 270.

[0236] In some examples, the sharp object 270 can include a cap portion 276 connected to the needle-like portion 272 (see Figure 11A ). In some examples, the needle-like portion 272 can be assembled to the support base 280 through the cap portion 276. In some examples, the cap portion 276 can include a first portion 277, a second portion 278, and a third portion 279 that are sequentially connected. In some examples, the first portion 277, the second portion 278, and the third portion 279 can be three columnar structures with different diameters. Additionally, in some examples, the diameter of the second portion 278 can 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.

[0237] In some examples, the support base 280 can include a sharp object fixing portion 282 (see Figure 11A ). In some examples, the number of the sharp object fixing portions 282 can be multiple, such as 2, 3, or 4. Additionally, the multiple sharp object fixing portions 282 can be circumferentially arranged around the central axis CA to clamp the cap portion 276. In some examples, the support base 280 can have multiple finger-like portions that converge with each other, and the cap portion 276 can be releasably clamped by the multiple finger-like portions. That is to say, the sharp object fixing portion 282 of the support base 280 can be formed as multiple finger-like portions that converge with each other. In this case, through the cooperation between the cap portion 276 of the sharp object 270 and the multiple finger-like portions of the support base 280, it is possible to facilitate the assembly and disassembly between the sharp object 270 and the support base 280.

[0238] In some examples, in a direction along the central axis CA and toward the proximal end, the sharp object fixing portion 282 may gradually converge toward the central axis CA. Thereby, a mechanism for clamping the cap portion 276 can be formed. 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 Figure 11A ). In some examples, the arm 283 may be elastic. When the sharp object 270 is assembled and combined with the support seat 280, the protrusion 284 of the sharp object fixing portion 282 may be embedded in the annular recess of the cap portion 276. The first portion 277, the third portion 279, and the annular recess cooperate with each other to fix the sharp object 270. The first portion 277 and the third portion 279 abut against the protrusion 284 from two directions respectively. Thereby, an undesired movement of the sharp object 270 along the central axis CA relative to the support seat 280 can be inhibited.
