Description

Technical Field

[0001] The present invention relates to an applicator and an applicator assembly, and more particularly to an applicator and an applicator assembly for subcutaneously inserting a transcutaneous sensor for sensing biological information.

Background Art

[0002] Chronic diseases such as diabetes require continuous management. Diabetes is characterized by almost no symptoms in the early stage, but as diabetes progresses, specific symptoms such as polydipsia, polyphagia, polyuria, weight loss, general malaise, itching of the skin, and difficulty in healing wounds on the hands and feet appear. If diabetes progresses further, complications such as visual impairment, hypertension, kidney disease, stroke, periodontal disease, muscle cramps and neuralgia, and gangrene may occur. In order to diagnose such diabetes and manage it so as not to progress to complications, it is necessary to perform systematic blood glucose measurement and treatment in parallel.

[0003] Diabetic patients or those who have not developed diabetes but have a blood sugar level above the reference value detected in their blood require continuous and regular blood glucose measurement to manage diabetes or prevent its progression.

[0004] Currently, the blood sampling method of collecting blood from a position such as a fingertip and measuring blood glucose in single units is the most common blood glucose measurement method. However, in the case of the blood sampling type blood glucose measurement method, there are limitations in continuous and regular blood glucose measurement due to the pain associated with blood sampling and the inconvenience caused thereby.

[0005] In recent years, in order to overcome the limitations of blood glucose measurement methods, blood glucose monitoring systems that use transdermal sensors inserted subcutaneously to continuously and regularly measure blood glucose levels have been developed and are in use. A blood glucose monitoring system using transdermal sensors generally consists of a wearable unit that includes a transdermal sensor and is provided to be wearable on the body, an applicator that is pre-coupled to the wearable unit so as to be inserted subcutaneously and simultaneously attached to the wearable unit, and a receiving unit that processes the information received from the wearable unit.

[0006] On the other hand, from the standpoint of hygiene and infection prevention, wearable units are usually provided to be discarded after one wear, and applicators are also usually provided to be discarded after one ejection. In other words, if the transcutaneous sensor is not inserted into the correct subcutaneous position, or if the wearable unit is not properly attached to the skin, the wearable unit and applicator must be discarded regardless of their respective lifespans. Therefore, in order to improve the convenience and cost-effectiveness of blood glucose monitoring systems that utilize transcutaneous sensors, an applicator is needed that allows for the accurate insertion of the transcutaneous sensor into the correct subcutaneous position and for the wearable unit to be stably attached to the skin. [Overview of the project] [Problems that the invention aims to solve]

[Modes for carrying out the invention]

[0048] Preferred embodiments of an applicator and applicator assembly according to one aspect of the present invention will be described in more detail below with reference to the accompanying drawings. Embodiments of the present invention can be modified in various ways, and the scope of the present invention should not be construed as being limited to the embodiments described below. These embodiments are provided to explain the present invention in more detail to those who have ordinary skill in the art to which the invention pertains. Accordingly, the shapes of the elements shown in the drawings may be exaggerated or emphasized for clarity.

[0049] The applicator and applicator assembly will be described in more detail below with reference to Figures 1 through 31.

[0050] Applicator Assembly Figure 1 is a perspective view showing an exemplary embodiment of the applicator assembly 1, and Figure 2 is a perspective view showing an exemplary embodiment of the applicator assembly 1 with the cap 50 removed. Figure 3 is a perspective view showing an exemplary embodiment of the wearable unit 20, and Figure 4 is a conceptual diagram showing an exemplary embodiment of the wearable unit 20 and remote terminal 5 worn on body B.

[0051] Applicator assembly 1 may include a wearable unit 20 and an applicator 10 that is assembled and provided together with the wearable unit 20. The user can use applicator assembly 1 with the wearable unit 20 and applicator 10 assembled. The wearable unit 20 and applicator 10 may be provided to the user in an assembled state during the manufacturing or distribution process, or they may be provided to the user in a separated state and then assembled and used by the user before actual use.

[0052] A cap 50 may be detachably positioned at one end of the applicator 10. The detachably positioned cap 50 at one end of the applicator 10 prevents arbitrary ejection of the applicator 10 and prevents external contaminants or moisture from flowing into the applicator assembly 1.

[0053] The cap 50 may be detachably bonded to one end of the applicator 10. When the cap 50 is bonded to the applicator 10, at least a portion of the applicator 10 and at least a portion of the cap 50 may be positioned to overlap horizontally.

[0054] The wearable unit 20 may include a sensor member 330. The sensor member may be a transcutaneous sensor member. The transcutaneous sensor member may be an invasive sensor or a non-invasive sensor including an optical sensor.

[0055] The transdermal sensor member 330 may include a sensor member 330 that is inserted subcutaneously into body B and senses biological information. The sensor member 330 may include a transdermal sensor member 330. The biological information sensed by the transdermal sensor member 330 can vary, but preferred biological information sensed by the transdermal sensor member 330 may be glucose concentration, ketones, glycated hemoglobin (HbA1c), fructosamine, 1,5-anhydroglucitol, other blood-based markers, or a combination thereof.

[0056] The sensor member 330 may be inserted into the user's body in at least a portion thereof. The sensor member 330 may include an insertion portion, which is inserted into the user's body in at least a portion thereof, and a body portion, which can be connected to an electronic device for transmitting information acquired from the sensor member 330. The sensor member 330 may further include a connecting portion that connects the insertion portion and the body portion. The connecting portion may be formed by bending to have a predetermined curvature, and the body portion and the insertion portion may be positioned on different planes by the connecting portion. The insertion portion may extend in a direction substantially perpendicular to the surface of the body to which the wearable unit 20 is attached when the wearable unit 20 is attached to the body. The body portion may extend in a direction substantially parallel to the surface of the body to which the wearable unit 20 is attached when the wearable unit 20 is attached to the body. The extending direction of the insertion portion may intersect with the extending direction of the body portion. The insertion portion, the connecting portion, and the body portion may be provided in a plate shape, but the shapes of the insertion portion, the connecting portion, and the body portion are not necessarily limited to such shapes.

[0057] The applicator 10 may be used to transmit the wearable unit 20 to a sensing position on the skin so that the end of the transcutaneous sensor member 330 included in the wearable unit 20 is inserted subcutaneously into the skin of body B. An adhesive member 430 may be provided at one end of the wearable unit 20. The wearable unit 20 can be held at the sensing position for a certain period of time by the adhesive member 430. The wearable unit 20 may be provided on the applicator 10 such that the adhesive surface of the adhesive member 430 is exposed to the outside when the cap 50 is removed from the applicator assembly 1.

[0058] While the sensing location is not limited to a specific location on body B, from the standpoint of convenience in daily life, it is preferable that the wearable unit 20 be attached to the skin of body B, such as the upper arm, thigh, or abdomen.

[0059] The wearable unit 20 is attached to the skin of body B to sense biometric information and can wirelessly transmit the sensed biometric data to an external terminal 5. The wireless transmission method is not particularly limited, and wireless transmission methods such as Bluetooth® (BT), Low Energy Bluetooth (BLE), Near Field Communication (NFC), and RFID can be applied. The external terminal 5 is also not particularly limited as long as it is a device capable of receiving and processing data. Non-limiting examples of external terminal 5 include mobile terminals, dedicated medical devices, PCs, and servers. Non-limiting examples include the wearable unit 20 continuously or periodically sensing the glucose concentration of body B and transmitting the glucose concentration data to the external terminal 5.

[0060] Wearable unit Figure 5 is a perspective view showing an exemplary embodiment of the sensor unit 30 with the needle 1401 coupled, and Figure 6 is a perspective view showing an exemplary embodiment of the coupling process between the sensor unit 30 and the transmission unit 40.

[0061] The wearable unit 20 may include a sensor unit 30 and a transmission unit 40. The wearable unit 20 may be arranged inside the applicator 10 as an integrated unit in which the sensor unit 30 and the transmission unit 40 are combined. In this case, during the injection process of the applicator 10, the integrated wearable unit 20, in which the sensor unit 30 and the transmission unit 40 are combined, can be attached to the skin of body B.

[0062] On the other hand, the sensor unit 30 and the transmitting unit 40 may be arranged in the applicator 10 in a state where they are separated from each other. In this case, the sensor unit 30 and the transmitting unit 40 may be coupled and transmitted to the sensing position during the process of the transcutaneous sensor member 330 being inserted subcutaneously. This may include all cases in which the sensor unit 30 and the transmitting unit 40 are coupled before the transcutaneous sensor member 330 is inserted subcutaneously, the sensor unit 30 and the transmitting unit 40 are coupled at the same time as the transcutaneous sensor member 330 is inserted subcutaneously, or the sensor unit 30 and the transmitting unit 40 are coupled after the transcutaneous sensor member 330 is inserted subcutaneously.

[0063] When the wearable unit 20 is placed inside the applicator 10 with the sensor unit 30 and the transmitting unit 40 separated, the sensor unit 30 and the transmitting unit 40 may be coupled during the subcutaneous insertion process of the transcutaneous sensor member 330 by the sensor unit 30 moving relative to the transmitting unit 40. That is, the subcutaneous insertion of the transcutaneous sensor member 330 may be performed by the sensor unit 30 moving toward the transmitting unit 40 while the transmitting unit 40 is in the sensing position.

[0064] When the sensor unit 30 moves towards the transmission unit 40, allowing for subcutaneous insertion of the transcutaneous sensor member 330, even with relatively small thrust applied to the transcutaneous sensor member 330, compared to the wearable unit 20 provided as an integrated unit, the transcutaneous sensor member 330 can be inserted into the correct position, effectively reducing pain and discomfort during the subcutaneous insertion process.

[0065] The transmitting unit 40 may include a transmitting unit housing 410 that forms the outer shape of the transmitting unit 40. The first transmitting unit housing 410a and the second transmitting unit housing 410b can be joined together to form the transmitting unit housing 410. Inside the transmitting unit housing 410, a battery which is a power source and an electronic unit for transmitting biometric information data may be provided. The joint between the first transmitting unit housing 410a and the second transmitting unit housing 410b may be further provided with a sealing portion to prevent external contaminants or moisture from flowing into the inside of the transmitting unit housing 410.

[0066] By applying adhesive to the area where the first transmission unit housing 410a and the second transmission unit housing 410b are joined, the bond between the first transmission unit housing 410a and the second transmission unit housing 410b can be made stronger. In this case, the adhesive may function as a seal, or another seal may be provided instead of adhesive. The seal may be formed by a separate mechanical component such as an O-ring, or by a chemical component such as adhesive, or a seal may be formed using both mechanical and chemical components.

[0067] A mounting groove 412 for housing and connecting the sensor unit 30 may be recessed inward from one end of the first transmitting unit housing 410a. The mounting groove 412 may be recessed inward from one surface of the first transmitting unit housing 410a. Preferably, the mounting groove 412 is formed in a shape corresponding to the sensor unit housing 310, which will be described later.

[0068] A side projection 414 may be provided in one region of the first transmitting unit housing 410a that forms the side surface of the anchoring groove 412, with a shape that protrudes toward the center of the anchoring groove 412. The side projection 414 may be divided into multiple parts by a dividing part 415. A sensor unit housing projection 311, which will be described later, may be arranged in the dividing part 415. The side projection 414 may be provided so as to extend along the circumferential direction of the anchoring groove 412, and may be divided into multiple regions by one or more dividing parts 415.

[0069] A first connection opening 416 connecting the inside and outside of the transmission unit housing 410 may be formed through one surface of the first transmission unit housing 410a that forms the anchoring groove 412. The transmission unit connection portion 420, which is connected to an electronic unit located inside the transmission unit housing 410, may be exposed to the outside through the first connection opening 416. The transmission unit connection portion 420 may be positioned so that its end protrudes outside the first connection opening 416 by passing through it. The shape of the transmission unit connection portion 420 is not limited to the shape shown in the drawings. The transmission unit connection portion 420 can be modified in various ways without limitation as long as it is a shape that can be electrically connected to a connection terminal to which it is intended to be connected. It is preferable that the transmission unit connection portion 420 be made of an electrically conductive material. It is more preferable that the transmission unit connection portion 420 be made of a material or structure that has self-elasticity from the viewpoint of contact safety.

[0070] A fastening latch 413 may be provided at the end of the first transmitting unit housing 410a that forms the boundary with the first connection opening 416, projecting inward toward the fastening groove 412. The fastening latch 413 may be coupled to a fastening ring 315, which will be described later. By fastening the fastening latch 413 to the fastening ring 315, the fastening latch 413 can help maintain a firm connection between the sensor unit 30 and the transmitting unit 40.

[0071] The insertion hole 411 may be formed in a shape that penetrates the first transmitting unit housing 410a and the second transmitting unit housing 410b inside the fixing groove 412. When the transcutaneous sensor member 330 is inserted subcutaneously, at least a portion of the needle body 1402 and at least a portion of the transcutaneous sensor member 330 may be inserted subcutaneously through the insertion hole 411. After the end of the transcutaneous sensor member 330 is inserted subcutaneously, the needle body 1402 can be discharged from the skin through the insertion hole 411, and the state in which one end of the transcutaneous sensor member 330 is inserted subcutaneously can be maintained.

[0072] An adhesive member 430 may be provided at one end of the second transmitting unit housing 410b opposite to the end where the adhesive groove 412 is formed. The adhesive member 430 attached to the skin can hold the wearable unit 20 in the sensing position for a certain period of time. The adhesive member 430 may comprise a first adhesive surface that adheres to the skin and a second adhesive surface that adheres to one end of the second transmitting unit housing 410b. To protect the first adhesive surface before it is attached to the skin, a protective film may be further provided on the first adhesive surface that adheres to the skin. The protective film may have any configuration.

[0073] Figure 6 shows an adhesive member 430 provided to have an area larger than one end of the second transmitting unit housing 410b, but the size and shape of the adhesive member 430 are not necessarily limited thereto. The adhesive member 430 may be provided to have an area corresponding to one end of the second transmitting unit housing 410b, or to have an area smaller than one end of the second transmitting unit housing 410b. The adhesive member 430 may be provided separately for the user to attach to the transmitting unit housing 410 during the subcutaneous insertion process of the transcutaneous sensor member 330, or it may be provided to maintain a state in which the adhesive member 430 is pre-attached to the transmitting unit housing 410 located inside the applicator assembly 1.

[0074] A transmission unit housing groove 417 may be provided at the side end of the transmission unit housing 410. For example, a transmission unit housing groove 417 recessed toward the inside of the transmission unit housing 410 may be provided at one side end of the second transmission unit housing 410b facing the adhesive member 430. The transmission unit housing groove 417 may be recessed symmetrically on both opposing ends of the first transmission unit housing 410a. On the other hand, the transmission unit housing groove 417 may be provided in multiple pairs, and these transmission unit housing grooves 417 may be spaced apart from each other along the circumferential direction of the second transmission unit housing 410b and formed symmetrically with respect to the second transmission unit housing 410b. The end of the locking portion 1164 provided on the transmission unit support portion 1160, which will be described later, may be positioned inside the transmission unit housing groove 417, in which case it is possible to effectively prevent the transmission unit 40 from detaching from the applicator 10 at will.

[0075] The transmitting unit housing groove 417 may be formed only in the second transmitting unit housing 410b, or it may be formed in both the first transmitting unit housing 410a and the second transmitting unit housing 410b, forming a single integrated groove. If the transmitting unit housing groove 417 is formed in both the first transmitting unit housing 410a and the second transmitting unit housing 410b, the transmitting unit housing groove 417 may be visible to the user when the user is looking down at the transmitting unit housing 410 (or when the user is looking at the first transmitting unit housing 410a while it is mounted in the user's sensing position). On the other hand, if the transmitting unit housing groove 417 is formed only in the second transmitting unit housing 410b, the transmitting unit housing groove 417 may not be visible to the user when the user is looking down at the transmitting unit housing 410 (or when the user is looking at the first transmitting unit housing 410a while it is mounted in the user's sensing position).

[0076] The sensor unit 30 may include a sensor unit housing 310 that forms the outer shape of the sensor unit 30, and a transcutaneous sensor member 330 disposed inside the sensor unit housing 310 and provided such that one end extends outside the sensor unit housing 310. When the wearable unit 20 is attached to the body B, at least one end of the transcutaneous sensor member 330 extending outside the sensor unit housing 310 can be kept inserted subcutaneously. Biological information can be sensed by the transcutaneous sensor member 330 inserted subcutaneously.

[0077] The sensor unit housing 310 may be formed by joining a first sensor unit housing 310a and a second sensor unit housing 310b together. The joint between the first sensor unit housing 310a and the second sensor unit housing 310b may be further provided with a sealing portion to prevent external contaminants or moisture from flowing into the inside of the sensor unit housing 310.

[0078] At least one adhesive member may be placed between the sensor unit housing 310 and the sensor member 330. The adhesive member may be provided so as to have adhesive force on both sides, which can make the bond between the sensor member 330 and the sensor unit housing 310 stronger. For example, double-sided tape may be placed on at least one of the upper and lower surfaces of the body portion of the sensor member 330, and the sensor member 330 and the sensor unit housing 310 can maintain a strong bond with each other through the double-sided tape placed between the body portion of the sensor member 330 and the sensor unit housing 310. On the other hand, although the case in which double-sided tape is used as the adhesive member has been described as an example, the adhesive member is not limited to double-sided tape, and various modified versions can be used as long as they are means that can improve the bond between the sensor member 330 and the sensor unit housing 310.

[0079] Multiple recesses 312 are formed at the side end of the second sensor unit housing 310b at regular intervals along the circumferential direction of the second sensor unit housing 310b, and a sensor unit housing projection 311 is provided on one surface of the first sensor unit housing 310a facing the second sensor unit housing 310b, projecting at positions corresponding to the multiple recesses 312.

[0080] The sensor unit housing protrusions 311 and recesses 312 may be provided such that, when the first sensor unit housing 310a and the second sensor unit housing 310b are joined, the sensor unit housing protrusions 311 are in close contact with the recesses 312, or the sensor unit housing protrusions 311 have a shape that allows them to press against the recesses 312. In order to maintain the state in which the sensor unit housing protrusions 311 are in close contact with or press against the recesses 312 when the first sensor unit housing 310a and the second sensor unit housing 310b are joined together, a more firmly joined state can be maintained between the first sensor unit housing 310a and the second sensor unit housing 310b. The sensor unit housing protrusions 311 and recesses 312 may be joined to each other by an interference fit.

[0081] On the other hand, the side projection 414 formed on the transmitting unit housing 410 may be provided in a shape that allows it to adhere closely to the side end of the second sensor unit housing 310b when the sensor unit 30 and the transmitting unit 40 are coupled together, or to pressurize the side end of the second sensor unit housing 310b. By the close contact between the side projection 414 and the second sensor unit housing 310b, or by the pressurization of the second sensor unit housing 310b by the side projection 414, the sensor unit 30 and the transmitting unit 40 can maintain a more firmly fixed state.

[0082] The sensor unit housing projection 311 may be formed in a position corresponding to a division 415 formed at the side end of the anchoring groove 412. During the process of coupling the sensor unit 30 and the transmitting unit 40, the division 415 guides the entry position of the sensor unit housing projection 311, allowing the sensor unit 30 to stably flow into the anchoring groove 412. When maintaining the coupled state of the sensor unit 30 and the transmitting unit 40, the sensor unit housing projection 311 may be positioned inside the division 415 formed at the side end of the anchoring groove 412. The sensor unit housing projection 311 may be in close contact with one surface of the first transmitting unit housing 410a forming the division 415, or one surface of the first transmitting unit housing 410a forming the division 415 may press against the sensor unit housing projection 311.

[0083] When the sensor unit 30 and the transmitting unit 40 are coupled, a second connection opening 316 connecting the inside and outside of the sensor unit housing 310 is formed through one end of the second sensor unit housing 310b, which is positioned to face the fastening groove 412. The sensor unit connection portion 320 connected to the transcutaneous sensor member 330 may be exposed to the outside through the second connection opening 316. When the sensor unit 30 and the transmitting unit 40 are coupled, the sensor unit connection portion 320 and the transmitting unit connection portion 420 may be in electrical contact with each other. Biological information data sensed by the transcutaneous sensor member 330 may be transmitted to an electronic unit provided in the transmitting unit 40 via the sensor unit connection portion 320 and the transmitting unit connection portion 420.

[0084] The sensor unit connection portion 320 may be formed on one surface of the transcutaneous sensor member 330 corresponding to the second connection opening 316, with a size and shape corresponding to the size and shape of the second connection opening 316. The sensor unit connection portion 320 may be formed on one surface of the transcutaneous sensor member 330 corresponding to the second connection opening 316, with a size smaller than the second connection opening 316, or on one surface of the transcutaneous sensor member 330 corresponding to the second connection opening 316, with a size larger than the second connection opening 316. From the viewpoint of electrical contact stability, it is preferable that the sensor unit connection portion 320 is formed to have a larger area than one surface of the transmitting unit connection portion 420 that contacts the sensor unit connection portion 320. The transmitting unit connection portion 420 may be provided in a shape divided into multiple parts, and the divided parts of the transmitting unit connection portion 420 may be arranged spaced apart from each other. On the other hand, the transmitting unit connection portion 420 may include a case in which a divided region is formed only in the region on the one end side that contacts the sensor unit connection portion 320. The sensor unit connection portion 320 may be divided into multiple portions and formed on one surface of the transcutaneous sensor member 330 so as to correspond to each of the multiple divided transmission unit connection portions 420, or it may be formed integrally on one surface of the transcutaneous sensor member 330 so as to correspond to all of the multiple divided transmission unit connection portions 420.

[0085] The transmitting unit connection portion 420 may include a body portion and a coating layer formed on the surface of the body portion. The coating layer may be formed by plating. The coating layer formed on the transmitting unit connection portion 420 may be formed as a single layer or as multiple layers.

[0086] The body of the transmitting unit connection portion 420 may be made of an elastic material and may be compressed by pressurization while in contact with the sensor unit connection portion 320. That is, the vertical height (or height in the first direction) of the transmitting unit connection portion 420 when the sensor unit 30 and the transmitting unit 40 are separated may be higher than the vertical height (or height in the first direction) of the transmitting unit connection portion 420 when the sensor unit 30 and the transmitting unit 40 are connected.

[0087] A boss 313 may be provided at one end of the second sensor unit housing 310b facing the transmitting unit 40, projecting in a shape corresponding to the insertion hole 411. A through hole 314 may be formed through the boss 313, connecting the inside and outside of the sensor unit housing 310.

[0088] One end of the transcutaneous sensor member 330, which is intended for subcutaneous insertion, may extend from inside the sensor unit housing 310 to outside the sensor unit housing 310 through a through hole 314. The through hole 314 may extend not only through the second sensor unit housing 310b but also through the first sensor unit housing 310a. The needle body 1402 may be positioned to pass through the through hole 314 with the sensor unit 30 and needle 1401 connected. In this case, one end of the transcutaneous sensor member 330 extending to the outside of the sensor unit housing 310 may be positioned outside the sensor unit housing 310 with the needle body 1402 housed inside it.

[0089] When the sensor unit 30 and the transmitting unit 40 are coupled, the circumferential side surface of the boss 313 and the inner surface of the transmitting unit housing 410 that forms the insertion hole 411 may be in close contact with each other or positioned in close proximity. This not only allows one end of the transcutaneous sensor member 330 to be inserted into the correct position, but also maintains a more firmly coupled state between the sensor unit 30 and the transmitting unit 40.

[0090] On the other hand, with the sensor unit 30 and the transmission unit 40 connected to each other, the circumferential side surface of the boss 313 and the inner surface of the transmission unit housing 410 that forms the insertion hole 411 can be kept in close contact with each other or closely positioned with each other. This effectively prevents external contaminants or moisture from flowing into the sensor unit connection part 320 and the transmission unit connection part 420 while the wearable unit 20 is attached to the body B.

[0091] A fastening ring 315 may be provided at the end of the second sensor unit housing 310b that forms the boundary with the second connection opening 316, projecting in a direction parallel to the projection direction of the transcutaneous sensor member 330. The fastening rings 315 may be provided in pairs symmetrically on both sides of the second connection opening 316, and the fastening latches 413 may also be provided in pairs symmetrically at positions corresponding to the fastening rings 315. During the coupling process of the sensor unit 30 and the transmitting unit 40, the fastening latches 413 are fixed to the fastening rings 315, and the mutual coupling of the fastening latches 413 and the fastening rings 315 allows the sensor unit 30 and the transmitting unit 40 to maintain a firmly coupled state.

[0092] The above description has been based on the example of a fastening latch 413 being provided on the first transmitting unit housing 410a and a fastening ring 315 being provided on the second sensor unit housing 310b. However, the description may also include a case where the fastening latch is provided on the second sensor unit housing 310b and the fastening ring 315 is provided on the first transmitting unit housing 410a. On the other hand, the fastening means between the sensor unit 30 and the transmitting unit 40 is not limited to a latch and a ring. Any means that does not hinder the sensor unit 30 from moving toward the transmitting unit 40 during the subcutaneous insertion process of the transcutaneous sensor member 330, and that prevents the sensor unit 30 from being separated from the transmitting unit 40 after the sensor unit 30 and the transmitting unit 40 are coupled together, can be modified and applied as fastening means.

[0093] A fixing groove 317 may be recessed on one surface of the first sensor unit housing 310a, and the tip of a fixing projection 1317 formed on the sensor unit carrier 130 (described later) may be inserted into the fixing groove 317. During the subcutaneous insertion process of the transcutaneous sensor member 330, the sensor unit 30 moves toward the transmitting unit 40 together with the sensor unit carrier 130, and the tip of the fixing projection 1317 can be kept inserted into the fixing groove 317 while the sensor unit 30 is moving. The sensor unit 30 can be stably supported and moved by the sensor unit carrier 130. After subcutaneous insertion of the transcutaneous sensor member 330, during the process of the user removing the applicator 10 from the skin, the fixing projection 1317 is discharged from the fixing groove 317, thereby releasing the fixing relationship between the sensor unit carrier 130 and the sensor unit 30.

[0094] An adhesive member may be further provided between the sensor unit 30 and the transmitting unit 40. Before the sensor unit 30 and the transmitting unit 40 are joined, the adhesive member may be placed on one surface of the second sensor unit housing 310b facing the adhesive groove 412, or inside the adhesive groove 412 facing the second sensor unit housing 310b, or adhesive members may be placed on both sides of one surface of the second sensor unit housing 310b or inside the adhesive groove 412. The adhesive member placed between the sensor unit 30 and the transmitting unit 40 allows the sensor unit 30 and the transmitting unit 40 to maintain a firm bond, preventing the sensor unit 30 from detaching from the transmitting unit 40 when the wearable unit 20 is attached to the user's sensing position.

[0095] With the sensor unit 30 and the transmission unit 40 coupled together, the first sensor unit housing 310a, the first transmission unit housing 410a, and the second transmission unit housing 410b can form the external appearance of the wearable unit 20.

[0096] With the sensor unit 30 and the transmission unit 40 coupled, the outer surface of the first sensor unit housing 310a and the outer surface of the first transmission unit housing 410a form a single surface, although they may be discontinuous. With the sensor unit 30 and the transmission unit 40 coupled, the outer surface of the first sensor unit housing 310a and the outer surface of the first transmission unit housing 410a may be positioned substantially in corresponding locations, or the outer surface of the first sensor unit housing 310a may be positioned recessed compared to the outer surface of the first transmission unit housing 410a. Because the outer surface of the first sensor unit housing 310a corresponds to or is recessed from the outer surface of the first transmission unit housing 410a, when the wearable unit 20 is mounted on the user's sensing position, unintended external impacts can be mitigated and prevented from being directly transmitted to the sensor unit 30, and damage or detachment of the sensor unit 30 due to external impacts can be effectively prevented.

[0097] Applicator Figures 7 and 8 are exploded perspective views showing an exemplary embodiment of the applicator assembly 1 with the cap 50 removed. For convenience of explanation, the direction substantially parallel to the insertion direction of the transcutaneous sensor member 330 will be defined as the first direction, and all directions substantially perpendicular to the first direction will be defined as the second direction, and the specific configuration of the applicator 10 and applicator assembly 1 will be described below.

[0098] The applicator 10 may be provided to transmit the wearable unit 20 to a sensing position on the skin. The applicator 10 may include a body housing 110 to which a transmitting unit 40 is detachably coupled at one end; a handle housing 120 positioned to move relative to the body housing 110 along a first direction when the transcutaneous sensor member 330 is subcutaneously inserted; a sensor unit carrier 130 to which a sensor unit 30 is detachably coupled at one end and positioned to move together with the handle housing 120 along the first direction; a needle carrier 140 comprising a needle body 1402 for subcutaneous insertion of the transcutaneous sensor member 330, and positioned detachably fixed to the sensor unit carrier 130; and an elastic member 150, with one end and the other end connected to the sensor unit carrier 130 and the needle carrier 140, respectively, which provides a driving force to expel the subcutaneously inserted needle body 1402 from the body B.

[0099] In addition to the applicator 10 described above, the applicator assembly 1 may also include a transmitting unit 40 detachably fixed to one end of the body housing 110 and a sensor unit 30 detachably fixed to one end of the sensor unit carrier 130. The applicator assembly 1 may further include a cap 50 detachably coupled to the handle housing 120 to block external exposure of the body housing 110 on which the transmitting unit 40 is located.

[0100] Handle housing Figures 9 and 10 are perspective and bottom views showing exemplary embodiments of the handle housing 120, and Figure 13 is a cross-sectional view of the handle housing 120 of Figures 9 and 10, cut in the direction A-A'.

[0101] The handle housing 120, together with the body housing 110, can form the outer shape of the applicator 10. The handle housing 120 may be grasped or pressed by the user during the subcutaneous insertion process of the transcutaneous sensor member 330. Figures 9, 10, and 13 show a cup-shaped handle housing 120, but the shape of the handle housing 120 is not necessarily limited to a cup shape. The handle housing 120 can be modified and applied in various shapes as long as it can achieve the functions described later. However, a cap 50 can be detachably attached to one end of the handle housing 120. Since the cap 50 can be detachably attached by screw connection, it is more preferable that one end of the handle housing 120, which has threads for screw connection, is provided to have a cylindrical structure.

[0102] A first internal space 1202 is formed inside the handle housing 120, and the first internal space 1202 can communicate with the outside through a first opening 1201 formed at one end of the handle housing 120. The push arm 1230 may extend in a first direction from one inner surface of the handle housing 120 facing the first opening 1201. The push arm 1230 may extend in the first direction at a position eccentric to one side from the center of one inner surface of the handle housing 120 facing the first opening 1201, or it may extend in the first direction at a position spaced apart from the inner side surface of the handle housing 120. The push arm 1230 may extend to a region that does not penetrate the first opening 1201. The push arm 1230 may include a main push arm plate 1230a positioned substantially parallel to the adjacent carrier fixing fence 1207, and a pair of extending push arm plates 1230b extending from both ends of the main push arm plate 1230a. The pair of extending push arm plates 1230b may be positioned substantially perpendicular to the main push arm plate 1230a, or they may be positioned substantially parallel. The push arm 1230 may be provided to interact with the fixing part 1130, which will be described later. During the assembly process of the applicator 10, the push arm 1230 pressurizes and moves the fixing part 1130, thereby releasing the temporary restriction on the movement of the sensor unit carrier 130 imposed by the fixing part 1130. The push arm 1230 may also be a means for pressurizing and moving the fixing part 1130 during the assembly process of the applicator 10.

[0103] The push arm slit 1232 may be shaped to divide the end of the push arm 1230, extending from the tip of the push arm 1230 in a direction opposite to the direction of protrusion of the push arm 1230. The extended portion 1136 provided on the fixing portion 1130, described later, flows into the push arm slit 1232, eliminating interference of the movement of the extended portion 1136 with respect to the push arm 1230 during the assembly process of the applicator 10 or the subcutaneous insertion process of the transcutaneous sensor member 330. Figures 9, 10, and 13 show a push arm 1230 formed symmetrically with respect to the push arm slit 1232, but the shape of the push arm 1230 is not necessarily limited to this. Any structure that allows the fixing portion 1130 to be pressurized and moved during the assembly process of the applicator 10 can be modified and applied to the push arm 1230 in various ways.

[0104] On one side of the push arm slit 1232, a wing section housing hole 1231 may be formed in a shape that extends along the first direction, penetrating the push arm 1230 in the thickness direction. On the other hand, the wing section housing hole 1231 may not completely penetrate the push arm 1230 in the thickness direction, but may be formed concavely from one surface of the push arm 1230 that comes into contact with the pressurizing movable wing section 1133 as the handle housing 120 moves in the first direction. The wing section housing hole 1231 may be provided in a shape and position corresponding to the pressurizing movable wing section 1133. If the pressurizing movable wing sections 1133 are provided in pairs, the wing section housing hole 1231 may be formed symmetrically with respect to the push arm slit 1232.

[0105] A barrier 1231' may be provided in the region of the end portion of the push arm 1230, shaped to close the wing portion housing hole 1231. That is, the push arm slit 1232 may be provided in a shape that extends to the tip of the push arm 1230, while the wing portion housing hole 1231 may be provided in a shape that does not extend to the tip of the push arm 1230 due to the barrier 1231'. As the handle housing 120 moves along the first direction, at least one end of the pressurized moving wing portion 1133 may flow into the wing portion housing hole 1231. When one end of the pressurized moving wing portion 1133 that has flowed into the wing portion housing hole 1231 comes into contact with the barrier 1231', the push arm 1230 can be restricted from moving in the direction opposite to the first direction.

[0106] The wing section housing holes 1231, barriers 1231', and push arm slits 1232 may be formed in the main push arm plate 1230a. The push arm slits 1232 may be formed on the central side of the main push arm plate 1230a, and the wing section housing holes 1231 and barriers 1231' may be formed in pairs in the outer region of the push arm slits 1232.

[0107] A carrier fixing fence 1207 may be provided on one inner surface of the handle housing 120 facing the first opening 1201, positioned adjacent to the push arm 1230. The carrier fixing fence 1207 may be erected in a shape corresponding to all or part of the periphery of one end of the sensor unit carrier 130. The carrier fixing fence 1207 may be provided in a shape surrounding the center of one inner surface of the handle housing 120. The carrier fixing fence 1207 may be provided to have a wider width than the push arm 1230, and may be formed to protrude from one inner surface of the handle housing 120 with a protrusion height lower than that of the push arm 1230. After assembly of the applicator 10, the sensor unit carrier 130 may be positioned so that at least one surface of the sensor unit carrier 130 is adjacent to the inner surface of the carrier fixing fence 1207, or in close contact with the inner surface of the carrier fixing fence 1207. In this case, the sensor unit carrier 130 may be positioned at a certain distance from one inner surface of the handle housing 120 facing the first opening 1201, or at a position where one end of the sensor unit carrier 130 is in contact with one inner surface of the handle housing 120 facing the first opening 1201.

[0108] When a user presses the handle housing 120 in a first direction for subcutaneous insertion of the transcutaneous sensor member 330, the sensor unit carrier 130 can either switch to a state where one end of the sensor unit carrier 130 contacts one inner surface of the handle housing 120 facing the first opening 1201, or maintain contact with one inner surface of the handle housing 120 facing the first opening 1201 and move along the first direction with the handle housing 120. In this case, the sensor unit carrier 130 can move in the first direction while maintaining a state where at least one surface of the sensor unit carrier 130 is firmly in contact with one inner surface of the carrier fixing fence 1207, effectively preventing the handle housing 120 from returning to its initial position after the subcutaneous insertion of the transcutaneous sensor member 330 is complete.

[0109] On the other hand, the sensor unit carrier 130 can move in the first direction together with the handle housing 120 while maintaining a certain distance from the inner surface of the handle housing 120 facing the first opening 1201, and during or after the subcutaneous insertion of the transcutaneous sensor member 330, one end of the sensor unit carrier 130 may switch to a state in which it contacts the inner surface of the handle housing 120 facing the first opening 1201. In this case, at least one surface of the sensor unit carrier 130 will be more firmly attached to the inner surface of the carrier fixing fence 1207 during or after the subcutaneous insertion of the transcutaneous sensor member 330, and the engagement of the carrier fixing fence 1207 with one end of the sensor unit carrier 130 will effectively prevent the handle housing 120 from returning to its initial position.

[0110] Guide projections 1210 extending along the first direction in a shape that protrudes toward the first internal space 1202 may be provided on the inner side surface of the handle housing 120 that forms the first internal space 1202. The tip of the guide projection 1210 may be located inside a handle housing guide groove 1142 recessed in the outer surface of the body housing 110, which will be described later. Through the interaction between the guide projection 1210 and the handle housing guide groove 1142, the direction of movement of the handle housing 120 moving in the first direction can be guided. The guide projections 1210 may be provided in pairs symmetrically on the inner side surface of the handle housing 120, and adjacent guide projections 1210 may be spaced apart from each other at a distance smaller than the width of the push arm 1230 or the width of the carrier fixing fence 1207.

[0111] The handle housing guide groove 1142 may also be recessed in a position corresponding to the guide projection 1210 and in a shape corresponding to the guide projection 1210. On the other hand, although the case in which the guide projection 1210 is formed on the handle housing 120 and the handle housing guide groove 1142 is formed on the body housing 110 has been described as an example, the case in which the guide groove is formed on the handle housing and the guide projection is formed on the body housing may also be included.

[0112] The first movement limiting portion 1220 may be formed to protrude from the inner side surface of the handle housing 120, which forms the first internal space 1202 of the handle housing 120, toward the center of the first internal space 1202. The first movement limiting portion 1220 may be located between a plurality of adjacent guide protrusions 1210 on one side of the handle housing 120, or it may be located opposite the push arm slit 1232. The first movement limiting portions 1220 may be provided in pairs symmetrically on the inner side surface of the handle housing 120. The symmetrically provided first movement limiting portions 1220 and the push arm slit 1232 may be located on the same extension line A-A'. The first movement limiting portion 1220 may be provided to have a greater width than the push arm slit 1232.

[0113] The first movement restricting portion 1220 can interact with the second movement restricting portion 1150 provided on the body housing 110, which will be described later. The interaction between the first movement restricting portion 1220 and the second movement restricting portion 1150 can restrict the handle housing 120, which is coupled to the body housing 110, from detaching from the body housing 110 at will, or from moving the handle housing 120 in the direction opposite to the first direction after the transcutaneous sensor member 330 is subcutaneously inserted.

[0114] The first movement restricting portion 1220 may be provided as a latch structure having a wedge-shaped cross-section including an inclined surface 1221 and a support surface 1222, but the shape of the first movement restricting portion 1220 is not necessarily limited thereto. The first movement restricting portion 1220 can be applied without limitation as long as it has a shape that can restrict the handle housing 120 from detaching arbitrarily from the body housing 110 via interaction with the second movement restricting portion 1150, or restrict the handle housing 120 from moving in a direction opposite to the first direction after the transcutaneous sensor member 330 has been subcutaneously inserted. The first movement restricting portion 1220 may be a means to restrict the handle housing 120 from detaching arbitrarily from the body housing 110, or it may be a means to restrict the handle housing 120 from moving in a direction opposite to the first direction after the transcutaneous sensor member 330 has been inserted into the subcutaneous tissue via interaction with the second movement restricting portion 1150.

[0115] A threaded portion 1240 for screw connection with the cap 50 may be provided on the outer surface of one end of the handle housing 120 in which the first opening 1201 is formed. The threaded portion 1240 formed on the handle housing 120 and the threaded portion 540 formed on the cap 50, which will be described later, can be screw-connected, allowing the handle housing 120 and the cap 50 to be connected to each other in a separable manner.

[0116] The outer surface of the handle housing 120 may be provided with a locking projection 1242 that protrudes outward from the outer surface of the handle housing 120 and extends along the circumferential direction of the handle housing 120. The locking projection 1242 may be provided adjacent to the area where the threaded portion 1240 is formed. Since the locking projection 1242 is provided in a structure that can abut against the tip of the cap 50, it is possible to prevent the threaded portion 1240 of the handle housing 120 and the threaded portion 540 of the cap 50 from being overtightened when the handle housing 120 and the cap 50 are screw-connected. Alternatively, the handle housing 120 and the cap 50 may be provided in a structure in which the locking projection 1242 and the end of the cap 50 are in close contact when the handle housing 120 and the cap 50 are connected to each other, and this close contact structure can effectively prevent external contaminants and moisture from flowing into the inside of the applicator assembly 1.

[0117] As shown in Figure 13, the first movement limiting portion 1220, the locking projection 1242, and the threaded portion 1240 are arranged sequentially on the handle housing 120 along the first direction, and the first movement limiting portion 1220 may be located inside the handle housing 120, while the locking projection 1242 and the threaded portion 1240 may be located outside the handle housing 120.

[0118] Figure 11 is a perspective view showing an exemplary embodiment of the handle housing 120 with a guide frame 1250, and Figure 12 is a bottom view showing an exemplary embodiment of the handle housing 120 with a guide frame 1250.

[0119] The handle housing 120 may further include guide frames 1250 positioned at both ends of the push arm 1230. The guide frames 1250 may be arranged in pairs and positioned symmetrically with respect to the push arm 1230 and at a constant distance from the push arm 1230. The guide frame 1250 may include a guide plate 1252 positioned at a constant distance from the extending push arm plate 1230b and extending along a direction parallel to the extending push arm plate 1230b; a first support plate 1251 extending from one end of the guide plate 1252 at a position relatively adjacent to the inner side wall of the handle housing 120; and a second support plate 1253 extending from the other end of the guide plate 1252 at a position relatively far from the inner side wall of the handle housing 120. The guide plate 1252, the first support plate 1251, and the second support plate 1253 may all extend in a first direction from one inner surface of the handle housing 120 facing the first opening 1201. The guide plate 1252, the first support plate 1251, and the second support plate 1253 may extend to a height corresponding to the push arm 1230, or to a region adjacent to the first opening 1201 beyond the tip of the push arm 1230. The guide plate 1252 may be provided to have a width corresponding to the extended push arm plate 1230b. A guide space 1254 extending in a first direction with a constant width may be formed between the guide plate 1252 and the extended push arm plate 1230b. During the coupling process of the body housing 110 and the handle housing 120, at least one end of the first auxiliary plate 1171, described later, may flow into the guide space 1254 and be positioned inside the guide space 1254.

[0120] The first support plate 1251 and the second support plate 1253 are arranged substantially perpendicular to the guide plate 1252, so that the first support plate 1251 and the second support plate 1253 can be arranged substantially parallel to each other. The second support plate 1253 may be provided to have a relatively wider width than the first support plate 1251. The first support plate 1251 and the second support plate 1253, provided at one end and the other end of the guide plate 1252, can provide more robust support to the guide plate 1252. The ends of the first support plate 1251 and the second support plate 1253 may be formed in a shape corresponding to the shape of the transmitting unit housing 1104.

[0121] Body Housing Figure 14 is a perspective view and a partially enlarged view showing an exemplary embodiment of the body housing 110, Figure 15 is a bottom view showing an exemplary embodiment of the body housing 110, and Figure 16 is a plan view showing an exemplary embodiment of the body housing 110. Figure 17 is a cross-sectional view of the body housing 110 cut along B-B' in Figure 16, and Figure 18 is a partial cross-sectional perspective view of the body housing 110 cut along C-C' in Figure 16.

[0122] The body housing 110 may be provided to support the sensor unit carrier 130 located inside the applicator 10, to guide the direction of movement of the sensor unit carrier 130, and to limit the range of movement of the sensor unit carrier 130. A transmitting unit 40 for attachment to a body B may be detachably fixed to one end of the body housing 110.

[0123] The body housing 110 may include a body housing torso 1100 having a circumferential surface shape corresponding to the first internal space 1202 of the handle housing 120. A second internal space 1102 may be provided inside the body housing torso 1100. The second internal space 1102 can communicate with the outside through a second opening 1101 formed at one end of the body housing 110 adjacent to the handle housing 120.

[0124] When the body housing 110 and the handle housing 120 are assembled to connect with each other, the second internal space 1102 formed in the body housing 110 and the first internal space 1202 formed in the handle housing 120 communicate with each other, forming an internal space (not shown) within the applicator 10 that is separated from the outside. On the other hand, the other end of the body housing 110 facing the end where the second opening 1101 is formed may be provided in a closed form.

[0125] Inside the body housing 110, a column 1110 may be erected, through which the first moving space 1111 is formed along a first direction. The column 1110 may be positioned to correspond to the carrier fixing fence 1207 provided on the handle housing 120. The column 1110 may include a plurality of partition walls 1112 erected extending from the inner surface of the closed other end of the body housing 110 along a direction opposite to the first direction. The plurality of partition walls 1112 may extend from the inside to the outside of the second internal space 1102, with the end of each partition wall 1112 protruding outside the second opening 1101. The plurality of partition walls 1112 may be arranged to surround the first moving space 1111 on its side. The plurality of partition walls 1112 may separate the second internal space 1102 from the first moving space 1111. The sensor unit carrier body 1310, needle carrier 140, and sensor unit 30 of the sensor unit carrier 130, which will be described later, can be moved to the transmitting unit 40 side via the first moving space 1111 during the subcutaneous insertion process of the transcutaneous sensor member 330.

[0126] On the other hand, although the following explanation will use a hexagonal columnar column 1110 as an example, the shape of the column 1110 of the present invention is not limited to this, and can be modified and applied in various ways as long as it is a shape that can provide a movement path for the sensor unit carrier body 1310, needle carrier 140, and sensor unit 30 during the subcutaneous insertion process of the transcutaneous sensor member 330.

[0127] A first acceleration latch 1118 may be provided on the outer surface of one or more of the multiple partition walls 1112, with a shape that protrudes outward from the outer surface of the partition wall 1112. The first acceleration latch 1118 may be provided in the outer region of the first moving space 1111, with a shape that protrudes away from the first moving space 1111. The first acceleration latch 1118 may be provided in the outer region of the second internal space 1102. The first acceleration latch 1118 interacts with a second acceleration latch 1328 provided on the sensor unit carrier 130, which will be described later, to provide a condition for the sensor unit carrier 130 to start moving, such that the sensor unit carrier 130 moves in the first direction only when a force of a certain amount or more is applied to the sensor unit carrier 130. In other words, the transcutaneous sensor member 330 is inserted subcutaneously only when a force sufficient to release the movement constraint of the second acceleration latch 1328 by the first acceleration latch 1118 is applied to the handle housing 120. This effectively avoids situations in which the transcutaneous sensor member 330 is arbitrarily ejected in circumstances unintended by the user.

[0128] On the other hand, for the transcutaneous sensor member 330 to be properly inserted subcutaneously, the needle body 1402 must move at a speed greater than or equal to the reference speed so that the tip of the needle body 1402 penetrates the skin surface. By applying acceleration conditions through the interaction of the first acceleration latch 1118 and the second acceleration latch 1328 so that the needle body 1402 is ejected at a speed greater than or equal to the reference speed, the proper subcutaneous insertion of the transcutaneous sensor member 330 can be effectively guided.

[0129] The first acceleration latch 1118 may be provided as a latch structure having a wedge-shaped cross-section including an inclined surface 1119a and a support surface 1119b, but the shape of the first acceleration latch 1118 is not necessarily limited thereto. The support surface 1119b may be provided at a position adjacent to the second opening 1101 than the inclined surface 1119a. The first acceleration latch 1118 can be modified and applied in various ways as long as it is capable of providing a condition for starting movement or acceleration of the sensor unit carrier 130 through interaction with the second acceleration latch 1328. The first acceleration latch 1118 may also be a means for providing a condition for starting movement or acceleration of the sensor unit carrier 130 through interaction with the second acceleration latch 1328.

[0130] The tip of the bulkhead 1112 equipped with the first acceleration latch 1118 may be provided with a bridge pressurizing section 1116 having a shape in which the cross-section decreases towards the tip. The bridge pressurizing section 1116 may be provided to pressurize the bridge 1330 provided on the sensor unit carrier 130, which will be described later, and deform or cut the bridge 1330. The bridge pressurizing section 1116 may be positioned opposite the bridge 1330 at a certain distance apart. As the sensor unit carrier 130 moves in the first direction, the distance between the bridge 1330 and the bridge pressurizing section 1116 may decrease. That is, in the initial step of the sensor unit carrier 130 moving in the first direction, the bridge 1330 provided on the sensor unit carrier 130 moves to a position in close contact with the bridge pressurizing section 1116, and the movement of the sensor unit carrier 130 in the first direction can be completed only when a force in the first direction is applied to the sensor unit carrier 130 to such an extent that the bridge 1330 is pressed by the bridge pressurizing section 1116 and cut or deformed.

[0131] If the bridge 1330 is not cut or deformed despite the movement of the sensor unit carrier 130 in the first direction, the bridge 1330 remains caught in the bridge pressurizing portion 1116, preventing the sensor unit carrier 130 from moving any further in the first direction. In other words, the interaction between the bridge 1330 and the bridge pressurizing portion 1116 not only effectively prevents the arbitrary ejection of the transcutaneous sensor member 330 in situations unintended by the user, but also provides sufficient acceleration conditions to ensure that the transcutaneous sensor member 330 is properly inserted subcutaneously. To eliminate mutual interference with the first acceleration latch 1118 and the second acceleration latch 1328, the bridge 1330 may be positioned so as not to overlap with the first acceleration latch 1118 and the second acceleration latch 1328 along the first direction. The bridge pressurizing portion 1116 may be located in the outer region of the second internal space 1102 and may be positioned to protrude more from the second opening 1101 than the first acceleration latch 1118.

[0132] During the assembly of the applicator assembly 1, the sensor unit carrier body 1310 flows into the first moving space 1111, so that at least one end of the carrier guide projection 1310a is positioned inside the carrier guide groove 1114, thereby allowing the bridge 1330 to be positioned opposite the bridge pressurizing portion 1116.

[0133] A carrier slit 1117 may be provided between the first acceleration latch 1118 and the bridge pressurizing section 1116, formed to penetrate the partition wall 1112 in a shape that cuts through the partition wall 1112 from the tip of the partition wall 1112 in a direction parallel to the direction opposite to the first direction. From the viewpoint of simplifying the structure, it is more preferable that the carrier slit 1117 is formed to penetrate between the first acceleration latch 1118 and the bridge pressurizing section 1116. On the other hand, Figure 14 shows the case where the first acceleration latch 1118, the carrier slit 1117, and the bridge pressurizing section 1116 are adjacent to each other, but the structure is not necessarily limited to this, and the first acceleration latch 1118, the carrier slit 1117, and the bridge pressurizing section 1116 may be arranged at a certain distance apart.

[0134] The carrier slit 1117 and the first moving space 1111 may be in communication, and the carrier slit 1117 may also connect the first moving space 1111 and the second internal space 1102. An extending arm guide groove 1324, recessed in a shape corresponding to the carrier slit 1117, may be provided along the first direction in the extending arm connection portion 1322 located between the sensor unit carrier body 1310 and the extending arm 1320.

[0135] As the sensor unit carrier 130 moves in the first direction, at least one end of the extending arm guide groove 1324 can flow into the carrier slit 1117. By having at least one end of the extending arm connection portion 1322, in which the extending arm guide groove 1324 is formed, flow into the carrier slit 1117, the obstruction of the movement of the extending arm connection portion 1322 in the first direction by the partition wall 1112 can be eliminated, and the movement of the sensor unit carrier 130 can be guided by the carrier slit 1117.

[0136] As the extended arm connection portion 1322 moves along the carrier slit 1117, the sensor unit 30, which is detachably fixed to the end of the sensor unit carrier 130, can be accurately transmitted to the anchoring groove 412 of the transmission unit 40.

[0137] Figures 14, 17, and 18 illustrate a case in which, as the sensor unit carrier 130 moves along a first direction, the bridge 1330 is positioned so that at least one end of the extending arm guide groove 1324 flows into the carrier slit 1117 after the bridge pressurization unit 1116 has started pressurizing the bridge 1330. However, the case may also include a case in which the bridge 1330 is positioned so that at least one end of the extending arm guide groove 1324 can flow into the carrier slit 1117 immediately before or simultaneously with the pressurization of the bridge 1330 by the bridge pressurization unit 1116.

[0138] The first acceleration latch 1118, the bridge pressurization section 1116, and the carrier slit 1117 may be provided at one end of the column 1110, or one or more of these may be provided in pairs at both ends of the column 1110 in a symmetrical configuration.

[0139] A carrier guide groove 1114 may be recessed in the inner surface of the partition wall 1112 forming the first moving space 1111 in a direction intersecting the first direction, and the carrier guide groove 1114 may extend along the first direction. For example, the carrier guide groove 1114 may be recessed from the inner surface of the partition wall 1112 in a shape that protrudes from the first moving space 1111 toward the second internal space 1102. The carrier guide groove 1114 may extend to a height corresponding to the total height of the partition wall 1112. The carrier guide groove 1114 may be formed in a partition wall 1112 adjacent to a partition wall 1112 in which the first acceleration latch 1118, bridge pressurizing section 1116, and carrier slit 1117 are formed, and multiple carrier guide grooves 1114 may be formed in a single partition wall 1112. The carrier guide grooves 1114 may be formed in a region adjacent to the partition wall 1112 where the first acceleration latch 1118, the bridge pressurization section 1116, and the carrier slit 1117 are formed. The carrier guide grooves 1114 may be provided in pairs symmetrically on both ends of the column 1110.

[0140] The sensor unit carrier 130 may be provided with a carrier guide projection 1310a formed in a shape corresponding to the carrier guide groove 1114 and at a position corresponding to the carrier guide groove 1114. The carrier guide projection 1310a may be formed to protrude from one end of the sensor unit carrier body 1310 in a direction intersecting the first direction and extending along the first direction. The carrier guide projection 1310a may be provided in the corner region of the sensor unit carrier body 1310. At least one end of the carrier guide projection 1310a may be positioned inside the carrier guide groove 1114. The tip of the carrier guide projection 1310a is positioned inside the carrier guide groove 1114, and the direction of movement of the sensor unit carrier 130 can be guided so that the sensor unit carrier 130 moves along the first direction.

[0141] The drawings illustrate four carrier guide protrusions 1310a positioned at each corner of the sensor unit carrier 130, and carrier guide grooves 1114 formed on the inner surface of the column 1110 at corresponding positions and in corresponding numbers. However, the shape and number of the carrier guide protrusions 1310a and carrier guide grooves 1114 are not necessarily limited to those shown in the drawings. The carrier guide protrusions 1310a and carrier guide grooves 1114 can be modified in various ways as long as their shape and number are sufficient to guide the movement of the sensor unit carrier 130 in the first direction. The carrier guide protrusions 1310a and carrier guide grooves 1114 may also be means for guiding the movement of the sensor unit carrier 130 in the first direction.

[0142] A partition support 1113 may be erected in the second internal space 1102 to support the column 1110. Multiple partition support 1113 may be provided, and they may be shaped to extend from inside the second internal space 1102 to a position adjacent to the second opening 1101. Since one end of the partition support 1113 is connected to the partition 1112 and the other end is connected to the inner side wall of the body housing section 1100, the structural safety and rigidity of the column 1110 and the body housing section 1100 can be improved.

[0143] The body extension portion 1140 may be provided in a shape that extends from one end of the body housing body portion 1100, where the second opening 1101 is formed, along a direction opposite to the first direction. The body extension portion 1140 may be provided at one end of the body housing body portion 1100 in a symmetrical pair facing each other. The body extension portion 1140 may be provided at a position facing the bulkhead 1112 where the carrier guide groove 1114 is formed. The body extension portion 1140 may be provided in a shape that extends to a region that protrudes further outward from the second opening 1101 than the tip of the column 1110. The handle housing guide groove 1142 may be formed in a shape that extends from the outer surface on the tip side of the body extension portion 1140 along the first direction to the outer surface on the other end side of the body housing body portion 1100. In other words, the handle housing guide groove 1142 may be recessed extending from the outer surface of the body extension portion 1140 to the outer surface of the body housing body portion 1100, in a shape that terminates the body extension portion 1140 and the body housing body portion 1100. The tip of the guide projection 1210 is positioned inside the handle housing guide groove 1142 and can guide the direction of movement of the handle housing 120 as it moves along the first direction. Multiple handle housing guide grooves 1142 may be recessed in a single body extension portion 1140 so as to be spaced apart from each other and extending along the first direction.

[0144] A second movement-restricting portion 1150 may be provided on the tip side of the fuselage extension portion 1140. A movement-restricting latch housing portion 1156 may be formed through the tip of the fuselage extension portion 1140, in a shape that partially cuts out the fuselage extension portion 1140 along the first direction from the tip of the fuselage extension portion 1140. The movement-restricting body 1151 is arranged to be housed in the movement-restricting latch housing portion 1156, and both ends on the central side of the movement-restricting body 1151 may be connected to the fuselage extension portion 1140 by body connection portions 1157. If two handle housing guide grooves 1142 are recessed in one fuselage extension portion 1140 so as to be spaced apart from each other and extending along the first direction, the movement-restricting latch housing portion 1156 may be formed between adjacently formed handle housing guide grooves 1142, and the second movement-restricting portion 1150 may also be positioned between adjacently formed handle housing guide grooves 1142. The movement restriction latch housing portion 1156 is formed to cut into the fuselage extension portion 1140 along the first direction to an area not exceeding the fuselage extension portion 1140, and the handle housing guide groove 1142 may be formed to extend from the end of the fuselage extension portion 1140 to the end of the body housing fuselage portion 1100.

[0145] Since both ends of the central side of the movement-restricting body 1151 are connected to the fuselage extension 1140 via the body connection 1157, when an external force is applied to the movement-restricting body 1151, the movement-restricting body 1151 can deform while housed in the movement-restricting latch housing 1156. The deformation of the movement-restricting body 1151 allows at least one end of the second movement-restricting portion 1150 to be pushed toward the first movement space 1111 and move. In this invention, the term “deformed” can be used interchangeably with “bent,” “curved,” “twisted” (including torsional deformation), or “distorted.” The deformation of the movement-restricting body 1151 is temporary and reversible, and it can return to its original position and / or shape once the external force is removed.

[0146] A first movement-restricting latch 1152 may be provided on the outer surface of one end of the movement-restricting body 1151, and a second movement-restricting latch 1154 may be provided on the outer surface of the other end of the movement-restricting body 1151. The first movement-restricting latch 1152 and the second movement-restricting latch 1154 may be provided in a shape that protrudes from the outer region of the first movement space 1111 toward the second internal space 1102. It is preferable that the first movement-restricting latch 1152 and the second movement-restricting latch 1154 be arranged to be spaced apart from each other along the first direction. The body connection portion 1157 may be provided in a region more adjacent to the first movement-restricting latch 1152 than to the second movement-restricting latch 1154.

[0147] The first movement-restricting latch 1152 may be provided as a latch structure having a wedge-shaped cross-section including a first inclined surface 1153a and a first support surface 1153b. The second movement-restricting latch 1154 may also be provided as a latch structure having a wedge-shaped cross-section including a second inclined surface 1155a and a second support surface 1155b. The first inclined surface 1153a, the first support surface 1153b, the second inclined surface 1155a, and the second support surface 1155b may be arranged in order along the first direction. The first movement-restricting latch 1152 and the second movement-restricting latch 1154 can interact with the first movement-restricting portion 1220 of the handle housing 120 to restrain the movement of the handle housing 120.

[0148] The support surface 1222 of the first movement limiting portion 1220 may be formed along a direction substantially parallel to the second direction, and the inclined surface 1221 of the first movement limiting portion 1220 may be inclined to be adjacent to the inner side wall of the handle housing 120 along the first direction from the end of the protruding support surface 1222. The support surface 1222 and the inclined surface 1221 may be arranged in order along the first direction. The first support surface 1153b of the first movement limiting latch 1152 may be formed along a direction substantially parallel to the second direction.

[0149] The first inclined surface 1153a of the first movement-restricting latch 1152 may be inclined to be adjacent to one end of the movement-restricting body 1151 along a direction opposite to the first direction from the end of the protruding first support surface 1153b. The second support surface 1155b of the second movement-restricting latch 1154 may be formed along a direction substantially parallel to the second direction. The second inclined surface 1155a of the second movement-restricting latch 1154 may be inclined to be adjacent to the other end of the movement-restricting body 1151 along a direction opposite to the first direction from the end of the protruding second support surface 1155b.

[0150] During the assembly of the handle housing 120 and the body housing 110, as the handle housing 120 moves relative to the body housing 110 in a first direction, the inclined surface 1221 of the first movement limiting portion 1220 can reach a state in contact with the first inclined surface 1153a of the first movement limiting latch 1152. Subsequently, as the handle housing 120 moves further along the first direction, one end of the movement limiting body 1151 deforms toward the second internal space 1102, thereby allowing the first movement limiting portion 1220 to pass through the first movement limiting latch 1152.

[0151] After the first movement-restricting part 1220 passes the first movement-restricting latch 1152, the movement-restricting body 1151 can be restored to its pre-deformation state. After the first movement-restricting part 1220 passes the first movement-restricting latch 1152 and the coupling between the handle housing 120 and the body housing 110 is completed, the support surface 1222 of the first movement-restricting part 1220 and the first support surface 1153b of the first movement-restricting latch 1152 are positioned facing each other. Therefore, even if a force is applied to the handle housing 120 in a direction opposite to the first direction, the support surface 1222 of the first movement-restricting part 1220 and the first support surface 1153b of the first movement-restricting latch 1152 support each other, preventing the handle housing 120 from detaching from the body housing 110 at will.

[0152] During the subcutaneous insertion process of the transcutaneous sensor member 330, the handle housing 120 moves in the first direction while the inclined surface 1221 of the first movement-restricting portion 1220 is in contact with the second inclined surface 1155a of the second movement-restricting latch 1154, causing the other end of the movement-restricting body 1151 to deform towards the second internal space 1102, and the first movement-restricting portion 1220 to pass through the second movement-restricting latch 1154. After the first movement-restricting portion 1220 has passed through the second movement-restricting latch 1154, the movement-restricting body 1151 can be restored to its pre-deformation state.

[0153] After the first movement limiting portion 1220 passes the second movement limiting latch 1154 and the subcutaneous insertion of the transcutaneous sensor member 330 is completed, the support surface 1222 of the first movement limiting portion 1220 and the second support surface 1155b of the second movement limiting latch 1154 may be positioned facing each other. The interaction between the support surface 1222 of the first movement limiting portion 1220 and the second support surface 1155b of the second movement limiting latch 1154 can restrict the handle housing 120 from moving in the direction opposite to the first direction. That is, after the subcutaneous insertion of the transcutaneous sensor member 330, the interaction between the first movement limiting portion 1220 and the second movement limiting portion 1150 can prevent the handle housing 120 from returning to its position before the insertion of the transcutaneous sensor member 330, thereby effectively preventing the reuse of the applicator 10 after injection.

[0154] Any of the multiple partition walls 1112 may be provided with a fixing portion 1130 that restricts arbitrary movement of the sensor unit carrier 130 during assembly of the applicator 10. Preferably, the fixing portion 1130 is provided on any of the partition walls 1112 in which the carrier guide groove 1114 is formed. At the tip of the partition wall 1112 in which the fixing portion 1130 is provided, a first cutting groove 1135a and a second cutting groove 1135b may be formed to cut through the partition wall 1112 from the tip of the partition wall 1112 in a first direction, and these grooves may be spaced apart from each other and run parallel to each other.

[0155] A support base 1134 may be erected between the first incision groove 1135a and the second incision groove 1135b in a direction parallel to the first direction. A fixed projection 1137, which protrudes toward the first movement space 1111, may be provided on one surface of the support base 1134 facing the first movement space 1111. A pressurized moving extension 1136, which extends from the other surface of the support base 1134, may be provided on the other surface of the support base 1134 facing the surface on which the fixed projection 1137 is formed. A pressurized moving part 1131 may be provided at the protruding tip of the pressurized moving extension 1136. The fixed projection 1137 and the pressurized moving extension 1136 may be arranged symmetrically to each other at the tip of the support base 1134. The fixed projection 1137 may be located in a region adjacent to the second opening 1101 more than the bridge pressurized part 1116.

[0156] The pressurized moving section 1131 may include a pressurized moving body section 1132 connected to the pressurized moving extension section 1136, and pressurized moving wing sections 1133 provided at both ends of the pressurized moving body section 1132. The pressurized moving wing sections 1133 may have a pressurized moving inclined surface 1133a that approaches the bulkhead 1112 along the first direction. The pressurized moving wing sections 1133 may be positioned at a distance from the pressurized moving extension section 1136 by the pressurized moving body section 1132 which is arranged to connect the pressurized moving extension section 1136 and the pressurized moving wing sections 1133. The pressurized moving extension section 1136, the pressurized moving body section 1132, and the pressurized moving wing sections 1133 may be formed to have substantially corresponding heights. As will be described later, a fixing groove 1340 with a shape corresponding to the fixing projection 1137 may be recessed on one surface of the sensor unit carrier body 1310.

[0157] If we define the position of the sensor unit carrier 130 when the handle housing 120 is not pressurized by the user (i.e., when the transcutaneous sensor member 330 has not been injected or subcutaneously inserted) as the initial position, and define the position of the sensor unit carrier 130 after the handle housing 120 has been pressurized by the user (i.e., after the transcutaneous sensor member 330 has been injected or subcutaneously inserted) as the insertion position, then it is preferable that the fixing groove 1340 is recessed on one surface of the sensor unit carrier body 1310 such that the fixing groove 1340 and the fixing projection 1137 of the sensor unit carrier 130 in the initial position are located in corresponding positions to each other.

[0158] During the process of inserting the sensor unit carrier body 1310 into the first moving space 1111 to assemble the applicator 10, the fixed projection 1137 contacts one surface of the sensor unit carrier body 1310, causing the support base 1134 to deform outward, and the fixing part 1130 maintains a state of being moved away from the first moving space 1111. Subsequently, when the sensor unit carrier body 1310 is pushed into the first moving space 1111 along the first direction until the fixed projection 1137 and the fixing groove 1340 are in corresponding positions, the tip of the fixed projection 1137 flows into and is positioned inside the fixing groove 1340, and the support base 1134 returns to its pre-deformation state.

[0159] The tip of the fixed projection 1137 flows into the fixed groove 1340, thereby restricting any movement of the sensor unit carrier 130 in the first direction or the direction opposite to the first direction, after which the coupling operation of the handle housing 120 and the body housing 110 may be performed.

[0160] During the process of connecting the handle housing 120 to the body housing 110, the tip of the push arm 1230 provided on the handle housing 120 may come into contact with the pressurizing inclined surface 1133a of the pressurizing moving wing 1133. When the tip of the push arm 1230 moves in the first direction while in contact with the pressurizing inclined surface 1133a, pressurizing the pressurizing moving wing 1133, the support base 1134 deforms outward, and the pressurizing moving part 1131 may be pushed away from the sensor unit carrier body 1310. As the pressurizing moving part 1131 is pushed away from the sensor unit carrier body 1310, the tip of the fixed projection 1137 moves to a position away from the fixed groove 1340, thereby releasing the restriction on arbitrary movement of the sensor unit carrier 130 by the fixed part 1130. The fixing part 1130 allows the sensor unit carrier 130 to maintain its initial position while the applicator 10 is assembled, thereby more effectively improving work efficiency during the assembly of the applicator 10.

[0161] On the other hand, the above description uses the example of a case in which the tip of the push arm 1230 pressurizes one end of the fixing part 1130 during the assembly process of the applicator 10, causing the fixing protrusion 1137 to be discharged from the fixing groove 1340. However, the description may also include a case in which the tip of the push arm 1230 pressurizes one end of the fixing part 1130 during the injection process of the transcutaneous sensor member 330, causing the fixing protrusion 1137 to be discharged from the fixing groove 1340. That is, the description may also include a case in which, during the assembly process of the applicator 10, the tip of the push arm 1230 is positioned adjacent to one end of the fixing part 1130, or in contact with one end of the fixing part 1130, and during the process in which the user pressurizes the handle housing 120 and the handle housing 120 moves from a first position to a second position, the tip of the push arm 1230 pressurizes one end of the fixing part 1130, causing the fixing protrusion 1137 to be discharged from the fixing groove 1340.

[0162] A transmission unit housing 1104 capable of accommodating a transmission unit 40 may be provided on the closed end of the body housing 110 facing the second opening 1101. The transmission unit housing 1104 may be recessed from the outside of the body housing 110 toward the second internal space 1102, or it may be physically separated from the second internal space 1102. The transmission unit housing 1104 may be provided in a region including the center of the closed end of the body housing 110. The transmission unit housing 1104 may be recessed in a shape corresponding to the transmission unit housing 410 so that it can accommodate the transmission unit housing 410 inside. When the transmission unit 40 is housed in the transmission unit housing 1104 and one end of the applicator 10 is brought into close contact with the skin, it is preferable that the transmission unit housing 1104 is recessed to a depth that allows the adhesive member 430 provided on the transmission unit 40 to be attached to the skin.

[0163] A third opening 1106 may be formed through one end of the body housing 110 in which the transmitting unit housing 1104 is formed, connecting the transmitting unit housing 1104 and the first moving space 1111. The transmitting unit housing 1104 and the first moving space 1111 may be in communication through the third opening 1106. The third opening 1106 may be formed to have a smaller area than the region in which the transmitting unit housing 1104 is formed. The transmitting unit 40 may be positioned in the transmitting unit housing 1104 such that an anchoring groove 412 formed on one surface of the transmitting unit 40 is located at a position corresponding to the third opening 1106. During the subcutaneous insertion process of the transcutaneous sensor member 330, the sensor unit 30 that has moved from the first moving space 1111 along the first direction may pass through the third opening 1106 and be transmitted to the anchoring groove 412 of the transmitting unit 40 housed in the transmitting unit housing 1104.

[0164] Transmitter unit support sections 1160 may be provided at both ends of the transmitter unit housing section 1104 to prevent the transmitter unit 40 from detaching from the transmitter unit housing section 1104. The transmitter unit support sections 1160 may be positioned adjacent to the third opening 1106. A pair of transmitter unit support sections 1160 may be positioned radially outward on one side of the first moving space 1111 and the other side opposite it. The fixing section 1130 may be positioned on the other side of the first moving space 1111 that does not overlap with the pair of transmitter unit support sections 1160. On the other hand, the number of transmitter unit support sections 1160 is not particularly limited, but if the transmitter unit support sections 1160 are provided in pairs, it becomes even more effective in preventing the transmitter unit 40 from detaching and in the stable transport of the applicator assembly 1. The transmitter unit support portion 1160 may be located in an area adjacent to the bulkhead 1112, which is provided with the first acceleration latch 1118, the bridge pressurizing portion 1116, and the carrier slit 1117. The transmitter unit support portion 1160 may be injection molded integrally with the body housing fuselage portion 1100.

[0165] Support hook housing spaces 1161 may be provided at both ends of the transmitter unit housing 1104, formed to penetrate one closed end of the body housing 110. Transmitter unit support hooks 1162, provided to support the transmitter unit 40, may be located within the support hook housing spaces 1161. The transmitter unit support hooks 1162 may be supported by a pair of support hook connectors 1166, each extending from the ends of the body housing 110 forming the support hook housing spaces 1161 and connected to both ends of the transmitter unit support hooks 1162. The pair of support hook connectors 1166 may be located in an area that partially overlaps with the bulkhead 1112, which is provided with the first acceleration latch 1118, the bridge pressurizing section 1116, and the carrier slit 1117. The transmitter unit support hook 1162 is connected to a support hook connection portion 1166 extending from the end of the body housing 110 and is located within the support hook housing space 1161. Therefore, if an external force is applied to the transmitter unit support hook 1162, the support hook connection portion 1166 may deform, and the position of the transmitter unit support hook 1162 may change.

[0166] Figures 15 and 16 show a support hook housing space 1161 formed to have a substantially rectangular cross-section, but the shape of the support hook housing space 1161 is not necessarily limited thereto. The support hook housing space 1161 may be formed to have a cross-sectional shape corresponding to the transmitting unit support hook 1162. As a non-limiting example, the support hook housing space 1161 may have a cross-sectional shape similar to a "Γ" or "Π" shape, and a pair of support hook housing spaces 1161 may be provided symmetrically with respect to the first moving space 1111.

[0167] The transmitting unit support hook 1162 may include a locking portion 1164 projecting toward the transmitting unit housing 1104, and a pressing portion 1165 projecting toward the opposite direction from the transmitting unit housing 1104. The locking portion 1164 may be formed in a shape that projects toward the first movable space 1111, and the pressing portion 1165 may be formed in a shape that projects toward the second internal space 1102. The locking portion 1164 and the pressing portion 1165 may be provided in shapes that extend toward opposite directions. The pressing portion 1165 may be the same as the locking portion 1164, or it may be provided to have a smaller width than the locking portion 1164 (wherein the width of the pressing portion 1165 and the locking portion 1164 may mean the lateral width based on the items shown in Figures 15 and 16). The pressing portion 1165 may be positioned eccentrically to one side with respect to the total width of the locking portion 1164. The locking portion 1164 is provided in an area that overlaps with the area where the first acceleration latch 1118, the bridge pressurizing portion 1116, and the carrier slit 1117 are located, and the pressed portion 1165 may be provided in an area that overlaps with the area where the bridge pressurizing portion 1116 is located.

[0168] The tip of the locking portion 1164 may be inserted into the transmission unit housing groove 417 of the transmission unit 40 housed in the transmission unit housing section 1104. The transmission unit 40 housed in the transmission unit housing section 1104 is supported by the locking portion 1164 with its tip inserted into the transmission unit housing groove 417, preventing it from being detached from the transmission unit housing section 1104 at will. The locking portion 1164 may have a shape in which the cross-section decreases towards the tip.

[0169] The pressed portion 1165 may be provided to have a height higher than the locking portion 1164. At one end of the pressed portion 1165 facing the extended arm pressing portion 1326, a pressed portion inclined surface 1165a may be formed, which is inclined to approach the transmitting unit housing portion 1104 along the first direction. That is, since the pressed portion inclined surface 1165a is provided at one end of the pressed portion 1165 facing the extended arm pressing portion 1326, the one end of the pressed portion 1165 facing the extended arm pressing portion 1326 may have a shape in which the cross-section decreases in the direction opposite to the first direction. When the extended arm pressing portion 1326 of the sensor unit carrier 130, which will be described later, pressurizes the pressed portion inclined surface 1165a, the transmitting unit support hook 1162 can move away from the transmitting unit housing portion 1104. In other words, during the subcutaneous insertion process of the transcutaneous sensor member 330, the sensor unit carrier 130 moves along the first direction together with the sensor unit 30, and at the same time as the sensor unit 30 is transmitted from the sensor unit carrier 130 to the transmission unit 40, or slightly before the sensor unit 30 is transmitted from the sensor unit carrier 130 to the transmission unit 40, the extended arm pushing portion 1326 pressurizes the inclined surface 1165a of the pushed portion, thereby releasing the restriction on the movement of the transmission unit 40 by the locking portion 1164. After the transmission of the sensor unit 30 to the transmission unit 40 is completed, the distance between the opposing locking portions 1164 may be wider than before the transmission of the sensor unit 30 to the transmission unit 40.

[0170] During the manufacturing of the applicator assembly 1, in the process of positioning the transmitting unit 40 in the transmitting unit housing 1104, the transmitting unit support hook 1162 is pressurized by the transmitting unit housing 410 and can move in a direction away from the transmitting unit housing 1104. Once the transmitted unit 40 is fully secured in the transmitting unit housing 1104, the moved transmitting unit support hook 1162 returns to its original position, thereby allowing the tip of the locking portion 1164 to flow into and position inside the transmitting unit housing groove 417.

[0171] The transmitting unit support 1160 is provided to release the movement constraint of the transmitting unit 40 only when intended by the worker or user during the assembly or use of the applicator assembly 1, thereby more effectively improving the convenience of assembly and use of the applicator assembly 1.

[0172] A grip arm guide groove 1120 extending along the first direction may be recessed outward on the inner surface of one or more of the partition walls 1112 that form the first moving space 1111. The grip arm guide groove 1120 may be formed in a partition wall 1112 adjacent to a partition wall 1112 that is provided with the first acceleration latch 1118, the bridge pressurizing section 1116, and the carrier slit 1117. The grip arm 1422 of the needle carrier 140, which will be described later, is positioned in the grip arm guide groove 1120 to guide the direction of movement of the needle carrier 140.

[0173] A stepped portion 1121 is formed in the center of the grip arm guide groove 1120, protruding to a height approximately corresponding to one surface of the partition wall 1112 in which the grip arm guide groove 1120 is formed. A first stepped inclined surface 1123 and a second stepped inclined surface 1124 may be formed at one end and the other end of the stepped portion 1121, respectively. That is, the grip arm guide groove 1120, the first stepped inclined surface 1123, the stepped portion 1121, the second stepped inclined surface 1124, and the grip arm guide groove 1120 may be continuously formed on the inner surface of the partition wall 1112 along a first direction. The first stepped inclined surface 1123 may be inclined to be adjacent to the first moving space 1111 along the first direction. The second stepped inclined surface 1124 may be inclined to be away from the first moving space 1111 along the first direction. In the case of a partition wall 1112 provided with a fixing portion 1130, a grip arm guide groove 1120, a first stepped inclined surface 1123, a stepped portion 1121, a second stepped inclined surface 1124, and a grip arm guide groove 1120 may be formed continuously along the first direction in the region adjacent to the first incision groove 1135a and the second incision groove 1135b, and these grip arm guide grooves 1120, first stepped inclined surface 1123, stepped portion 1121, second stepped inclined surface 1124, and grip arm guide grooves 1120 may be formed in a symmetrical shape with respect to the support base 1134.

[0174] During the assembly of the applicator assembly 1, the needle carrier 140 flows into the first movement space 1111 along the first direction, and the needle carrier 140 can move to its initial position with the grip arm 1422 positioned in the grip arm guide groove 1120. When the needle carrier 140 is in its initial position, the grip arm projection 1424 formed on the grip arm 1422 may pass the first stepped inclined surface 1123, or it may be positioned just before passing the first stepped inclined surface 1123. Subsequently, as the needle carrier 140 moves further along the first direction, the grip arm projection 1424 may come into close contact with the stepped portion 1121 and be pressed inward. The sensor unit 30 can maintain a firmly fixed state by the inwardly pressed grip arm 1422 during the process of the needle carrier 140 moving.

[0175] As the needle carrier 140 moves further along the first direction to the insertion position, the grip arm projection 1424 passes the second stepped inclined surface 1124, and the pressure on the grip arm projection 1424 by the stepped portion 1121 is released as a result of the grip arm projection 1424 passing the second stepped inclined surface 1124. In other words, during the subcutaneous insertion of the transcutaneous sensor member 330, the pressure on the grip arm projection 1424 by the stepped portion 1121 can be released at the same time as, or before, the sensor unit 30 is transmitted to the anchoring groove 412 of the transmitting unit 40.

[0176] This not only effectively prevents the sensor unit 30 from detaching from its designated position inside the applicator 10 during the subcutaneous insertion process of the transcutaneous sensor member 330, but also effectively prevents the sensor unit 30 from being pulled in the opposite direction to the first direction by the grip arm 1422 immediately after subcutaneous insertion of the transcutaneous sensor member 330.

[0177] Figure 19 is a plan view showing an exemplary embodiment of the body housing 110 with an auxiliary plate 1171, Figure 20 is a partial cross-sectional perspective view of the body housing 110 cut along C-C' in Figure 19, and Figure 21 is a bottom view further showing the position of the auxiliary plate 1171 in Figure 12 to illustrate the positional relationship between the guide frame 1250 and the auxiliary plate 1171.

[0178] The body housing 110 may further include a first auxiliary plate 1171 and a second auxiliary plate 1172, which are provided to connect one and the other opposing end of the column 1110 to the inner walls of the body housing body portion 1100 and the body extension portion 1140 that are opposite to the one and the other end of the column 1110. The first auxiliary plate 1171 may be positioned to connect one side end of the column 1110, where the fixing portion 1130 is formed, to the inner walls of the body housing body portion 1100 and the body extension portion 1140 that are opposite to it. The second auxiliary plate 1172 may be positioned opposite to the first auxiliary plate 1171 with respect to the column 1110 to connect the other side end of the column 1110 to the inner walls of the body housing body portion 1100 and the body extension portion 1140 that are opposite to it. The first auxiliary plate 1171 and the second auxiliary plate 1172 are arranged on the same line, and the first auxiliary plate 1171 may be provided to have a wider width than the second auxiliary plate 1172. The first auxiliary plate 1171 and the second auxiliary plate 1172 may each be erected extending from the inner surface of the closed other end of the body housing 110 along a direction opposite to the first direction. The first auxiliary plate 1171 and the second auxiliary plate 1172 may each be erected extending from the inner surface of the closed other end of the body housing 110 along a direction opposite to the first direction to have a height corresponding to the column 1110.

[0179] The first auxiliary plate 1171 may be positioned to connect the inner walls of the body housing fuselage portion 1100 and fuselage extension portion 1140 facing the bulkhead 1112 on which the fixing portion 1130 is formed. The second auxiliary plate 1172 may be positioned to connect the inner walls of the body housing fuselage portion 1100 and fuselage extension portion 1140 facing the bulkhead 1112 on which the fixing portion 1130 is formed. The first auxiliary plate 1171 and the second auxiliary plate 1172 may each be provided in pairs. The first auxiliary plate 1171 may each be positioned to connect the inner walls of the body housing fuselage portion 1100 and fuselage extension portion 1140 facing the outer end of the bulkhead 1112 corresponding to the carrier guide groove 1114 formed adjacent to the fixing portion 1130. The second auxiliary plate 1172 may be positioned to connect the inner walls of the body housing fuselage portion 1100 and the fuselage extension portion 1140 facing the outer end of the bulkhead 1112 corresponding to the carrier guide groove 1114 formed in the bulkhead 1112 facing the bulkhead 1112 on which the fixing portion 1130 is formed. The pair of first auxiliary plates 1171 and the pair of second auxiliary plates 1172 may be positioned parallel to each other at a constant distance apart. The first auxiliary plate 1171 and the second auxiliary plate 1172, which are positioned symmetrically with respect to the column 1110, may be positioned on the same line.

[0180] Since the column 1110 is supported by a first auxiliary plate 1171 and a second auxiliary plate 1172, which are arranged to connect one end and the other end of the column 1110 with the body housing fuselage portion 1100 and fuselage extension portion 1140 facing these ends, the column 1110 can have a more robust support structure.

[0181] The side ends of the first auxiliary plate 1171 may each be provided with projections 1171a formed in a shape that protrudes along a direction parallel to the partition wall 1112 on which the fixing portion 1130 is formed. The projections 1171a may each protrude in a direction away from each other from the side end surface of the first auxiliary plate 1171 outside the area where the fixing portion 1130 is located. The projections 1171a may extend along the first direction from the end region of the first auxiliary plate 1171 that protrudes outside the second internal space 1102. The projections 1171a may extend from the end region of the first auxiliary plate 1171 to the inner surface of the other closed end of the body housing 110. With the body housing 110 and the handle housing 120 joined together, one side surface of the first support plate 1251 facing the projections 1171a may be in close contact with the side end surface of the projections 1171a or positioned in close contact with it. On the other hand, with the body housing 110 and the handle housing 120 joined together, one side and the other side of the first support plate 1251 may be in close contact with one side of the guide plate 1252 and one side of the extended push arm plate 1230b, or positioned in close proximity.

[0182] The guide frame 1250 and the first auxiliary plate 1171 assist in the coupling of the body housing 110 and the handle housing 120 via interaction, so that the end of the first auxiliary plate 1171 flows into the guide space 1254, allowing the body housing 110 and the handle housing 120 to be coupled at a predetermined coupling position. During the injection process of the transcutaneous sensor member 330, at least one end of the first auxiliary plate 1171 is kept positioned inside the guide space 1254, effectively preventing the handle housing 120 from moving in directions other than the first direction.

[0183] Sensor unit carrier Figures 22 and 23 are perspective views showing exemplary embodiments of the sensor unit carrier 130.

[0184] The sensor unit carrier 130 may be positioned inside the applicator assembly 1 so as to move in a first direction together with the needle carrier 140 and the sensor unit 30 during the subcutaneous insertion process of the transcutaneous sensor member 330. After subcutaneous insertion of the transcutaneous sensor member 330, the needle carrier 140 may move to a retracted position so that the needle body 1402 is ejected from the skin, while the sensor unit carrier 130 may be held in the insertion position.

[0185] The sensor unit carrier 130 includes a sensor unit carrier body 1310 that constitutes the framework of the sensor unit carrier 130, and the sensor unit carrier body 1310 may be provided with a second movement space 1312 that is open at the front. With the sensor unit carrier 130 positioned in the column 1110, the open front of the second movement space 1312 may be positioned toward a partition wall 1112 facing the fixed portion 1130. The needle carrier 140 can be moved to a retracted position via the second movement space 1312 after the transcutaneous sensor member 330 has been subcutaneously inserted.

[0186] A fourth opening 1314 may be formed through one end of the sensor unit carrier body 1310 adjacent to the third opening 1106 formed in the body housing 110, connecting the outside to the second moving space 1312. The needle body 1402 may protrude to the outside of the sensor unit carrier body 1310 through the fourth opening 1312'.

[0187] A fixing projection 1317 is provided on one end face of the sensor unit carrier body 1310 facing the third opening 1106, with a shape that protrudes toward the third opening 1106. The tip of the fixing projection 1317, which is inserted into the fixing groove 317 formed in the sensor unit 30, allows the sensor unit 30 to be firmly fixed by the sensor unit carrier 130. The fixing projection 1317 is positioned on the corner side of one end face of the sensor unit carrier body 1310, and multiple projections may be provided and arranged symmetrically.

[0188] A carrier guide projection 1310a, which protrudes outward, may be provided along the first direction at the corner of the side end of the sensor unit carrier body 1310. Based on the state in which the sensor unit carrier 130 is positioned in the column 1110, the carrier guide projection 1310a may protrude toward the partition wall 1112 in which the carrier guide groove 1114 is formed and extend along the first direction. A carrier guide projection 1310a positioned on the open front side of the second moving space 1312 may be provided to be shorter in length than a carrier guide projection 1310a positioned on the opposite side. Compared to a carrier guide projection 1310a positioned on the open front side of the second moving space 1312, a carrier guide projection 1310a positioned on the opposite side may be provided to have a shape that extends further in the direction opposite to the first direction. The tip of the carrier guide projection 1310a may be positioned inside the carrier guide groove 1114 formed in the column 1110. The carrier guide projection 1310a and the carrier guide groove 1114 can guide the direction of movement of the sensor unit carrier body 1310 as it moves along the first direction.

[0189] On the inner side surface of the sensor unit carrier body 1310 forming the second moving space 1312, a needle carrier guide projection 1313 may be provided, projecting from the inner side surface of the sensor unit carrier body 1310 toward the center of the second moving space 1312 and extending along the first direction. The needle carrier guide projection 1313 may be provided to be longer than the carrier guide projection 1310a located on the open front side of the second moving space 1312, and shorter than the carrier guide projection 1310a located opposite the open front side of the second moving space 1312. The tip of the needle carrier guide projection 1313 may be located inside a needle guide groove 1415 formed in the needle carrier body 1410, which will be described later. The needle carrier guide projection 1313 and the needle guide groove 1415 can guide the direction of movement of the needle carrier 140 moving in a direction opposite to the first direction.

[0190] A sliding groove 1319 may be provided on the inner side surface of the sensor unit carrier body 1310 adjacent to the handle housing 120. The sliding groove 1319 is recessed from the inner side surface on the tip side of the sensor unit carrier body 1310 and extends along the first direction. Preferably, the sliding groove 1319 is formed adjacent to the open front side of the second movement space 1312. The sliding groove 1319 and the needle carrier guide projection 1313 may be arranged at positions separated along the first direction and not overlapping each other.

[0191] A sensor unit carrier detent 1318, which has a detent inclined surface 1318a and a detent restraining surface 1318b formed thereon, may be arranged in the first direction end region of the sliding groove 1319. In order to maintain the state in which the needle carrier latch 1434 of the needle carrier 140, which will be described later, is restrained by the sensor unit carrier detent 1318, the needle carrier 140 can move in the first direction together with the sensor unit carrier 130 during the subcutaneous insertion process of the transcutaneous sensor member 330. The detent restraining surface 1318b may be formed along a direction substantially parallel to the second direction, and the detent inclined surface 1318a may be inclined to be adjacent to the sliding groove 1319 along a direction opposite to the first direction from one protruding end of the detent restraining surface 1318b.

[0192] The extending arms 1320 may project outward from the outer surfaces on both sides of the sensor unit carrier body 1310 and extend along a first direction. The extending arms 1320 may be provided so as to extend outward from the side end of the sensor unit carrier body 1310 in the region overlapping with the sliding groove 1319, and may be provided in pairs to form a symmetrical shape with respect to the sensor unit carrier body 1310. An extending arm connection portion 1322 may be provided between the sensor unit carrier body 1310 and the extending arm 1320, forming a closed region. The extending arm connection portion 1322 may extend from the region overlapping with the sliding groove 1319 in a second direction toward the region overlapping with the needle carrier guide projection 1313 in a second direction. An extending arm guide groove 1324 may be formed in a concave shape in the extending arm connection portion 1322, extending along the first direction. The extended arm guide groove 1324 may be formed to extend to the end of the extended arm connection portion 1322, which is located in a region that overlaps with the needle carrier guide projection 1313 in a second direction. The extended arm guide groove 1324 may be formed in a symmetrical pair on opposing sides of the extended arm connection portion 1322. Preferably, the extended arm guide groove 1324 is formed in a position and shape corresponding to the carrier slit 1117 of the column 1110.

[0193] As the sensor unit carrier body 1310 moves along a first direction to insert the transcutaneous sensor member 330 subcutaneously, the extended arm connection portion 1322, which has an extended arm guide groove 1324 formed therein, can flow into the carrier slit 1117 of the column 1110. The carrier slit 1117 and the extended arm guide groove 1324 not only guide the direction of movement of the sensor unit carrier 130 as it moves in the first direction, but also eliminate interference of the column 1110 with the movement of the sensor unit carrier 130 in the first direction.

[0194] A second acceleration latch 1328 may be provided on one surface of the extending arm 1320 facing the sensor unit carrier body 1310, projecting toward the sensor unit carrier body 1310. The second acceleration latch 1328 may be positioned in a region that overlaps with the needle carrier guide projection 1313 in the second direction. The second acceleration latch 1328 may be formed symmetrically so as to project toward the sensor unit carrier body 1310 from each extending arm 1320. The second acceleration latch 1328 may have a support surface 1328b formed in a direction substantially parallel to the second direction, and an inclined surface 1328a that is inclined and positioned adjacent to the one surface of the extending arm 1320, gradually moving toward the one surface of the extending arm 1320 along the first direction from the protruding end of the support surface 1328b. The second acceleration latch 1328 protrudes from one side of the extending arm 1320 facing the sensor unit carrier body 1310. However, the second acceleration latch 1328 may be positioned and sized so that even if the shape of the extending arm 1320 deforms, the tip of the second acceleration latch 1328 facing the sensor unit carrier body 1310 does not come into contact with the sensor unit carrier body 1310. The second acceleration latch 1328 can prevent the applicator 10 from being ejected unintentionally by the user through interaction with the first acceleration latch 1118 provided on the body housing 110.

[0195] The second acceleration latch 1328, through interaction with the first acceleration latch 1118 provided on the body housing 110, can provide sufficient acceleration conditions to the needle body 1402 when the transcutaneous sensor member 330 is inserted subcutaneously, and can prevent the sensor unit carrier 130 from moving in the opposite direction to the first direction after the transcutaneous sensor member 330 has been inserted subcutaneously.

[0196] When the sensor unit carrier 130 is in its initial position, the inclined surface 1119a of the first acceleration latch 1118 and the inclined surface 1328a of the second acceleration latch 1328 can be separated from each other while facing each other, or they can remain in contact. When the user presses the handle housing 120 in the first direction and the sensor unit carrier 130 moves in the first direction, the inclined surface 1119a of the first acceleration latch 1118 and the inclined surface 1328a of the second acceleration latch 1328 can move while in contact with each other and rubbing against each other. At this time, the extending arm 1320 can deform outward. Subsequently, as the sensor unit carrier 130 moves in the first direction, the inclined surface 1328a of the second acceleration latch 1328 is released from contact with the inclined surface 1119a of the first acceleration latch 1118, and the support surface 1119b of the first acceleration latch 1118 and the support surface 1328b of the second acceleration latch 1328 may switch to a state where they face each other.

[0197] Subcutaneous insertion of the transcutaneous sensor member 330 may be performed after the support surface 1119b of the first acceleration latch 1118 and the support surface 1328b of the second acceleration latch 1328 are switched to a state where they face each other. After subcutaneous insertion of the transcutaneous sensor member 330, the opposing support surfaces 1119b of the first acceleration latch 1118 and 1328b of the second acceleration latch 1328 can restrict the movement of the sensor unit carrier 130 in the direction opposite to the first direction.

[0198] In relation to the shapes of the first acceleration latch 1118 and the second acceleration latch 1328, a latch structure having a wedge-shaped cross-section including inclined surfaces 1119a, 1328a and support surfaces 1119b, 1328b has been described as an example. However, the shapes of the first acceleration latch 1118 and the second acceleration latch 1328 are not necessarily limited to this. Any structure that can prevent the applicator 10 from being ejected unintentionally by the user through interaction, provide sufficient acceleration conditions to the needle body 1402 when the transcutaneous sensor member 330 is inserted subcutaneously, and prevent the sensor unit carrier 130 from moving in a direction opposite to the first direction after the transcutaneous sensor member 330 has been inserted subcutaneously can be modified and applied to the first acceleration latch 1118 and the second acceleration latch 1328 in various ways. The first acceleration latch 1118 and the second acceleration latch 1328 may, through interaction, be means to prevent the applicator 10 from being arbitrarily ejected in a situation unintended by the user, means to provide sufficient acceleration conditions to the needle body 1402 when inserting the transcutaneous sensor member 330 into the subcutaneous tissue, or means to prevent the sensor unit carrier 130 from moving in a direction opposite to the first direction after the transcutaneous sensor member 330 has been inserted into the subcutaneous tissue.

[0199] The bridge 1330 may be positioned between the extending arm 1320 and the sensor unit carrier body 1310. The bridge 1330 may be configured to restrict the movement of the sensor unit carrier from its initial position to its insertion position. The bridge 1330 may be configured to break or deform when pressurized by the bridge pressurizing section 1116. One end and the other end of the bridge 1330 may be provided to connect to one side of the sensor unit carrier body 1310 and to one side of the extending arm 1320 facing the sensor unit carrier body 1310, respectively. Alternatively, only one end of the bridge 1330 may be provided to connect to one side of the sensor unit carrier body 1310 or to one side of the extending arm 1320 facing the sensor unit carrier body 1310. The bridge 1330 may be positioned in a region overlapping with the needle carrier guide projection 1313 in a second direction, and between the extending arm connection section 1322 and the second acceleration latch 1328. The bridge 1330 may be positioned adjacent to the second acceleration latch 1328 by the extended arm connection portion 1322.

[0200] The bridge 1330 is preferably formed at a position corresponding to the bridge pressurization portion 1116 of the column 1110. One or more fragile portions 1332 having a relatively thin thickness may be formed on the bridge 1330. The sensor unit carrier 130 can move to the insertion position only if the bridge 1330, which is in contact with the bridge pressurization portion 1116, is severed during the process in which the user pressurizes the handle housing 120 in the first direction and the sensor unit carrier 130 moves in the first direction.

[0201] The weak point 1332 is a region intended to be cut when the bridge 1330 is pressurized by the bridge pressurizing section 1116, and is preferably designed so that the weak point 1332 is cut only when the force applied to the bridge 1330 is typically the force applied when a user pressurizes the handle housing 120 for subcutaneous insertion of the transcutaneous sensor member 330. Here, the force typically applied when a user pressurizes the handle housing 120 for subcutaneous insertion of the transcutaneous sensor member 330 may mean the level of force that a user of the applicator assembly 1 applies to the handle housing 120 with the intention of subcutaneous insertion of the transcutaneous sensor member 330, rather than the force typically applied during the assembly and transport of the applicator assembly 1.

[0202] Although a region having a thickness thinner than the bridge 1330 has been described as an example of a weak area 1332, the weak area 1332 is not necessarily limited to a structure having a relatively thin thickness. The weak area 1332 can mean a region with lower fracture strength relative to the entire bridge 1330 by applying a different material or a weak structure. Through the interaction between the bridge 1330 and the bridge pressurizing portion 1116, it is possible not only to prevent the applicator 10 from being ejected unintentionally by the user, but also to provide sufficient acceleration conditions to the needle body 1402 when the transcutaneous sensor member 330 is inserted subcutaneously.

[0203] The above description has been based on the example of a case where the bridge 1330 is provided on the sensor unit carrier 130 and the bridge pressurizing section 1116 is provided at the tip of the partition wall 1112. However, the description may also include a case where the bridge structure is provided on the partition wall 1112 and the pressurizing section for cutting the bridge structure is provided on the sensor unit carrier 130.

[0204] An extending arm pushing portion 1326 having an inclined surface 1326a may be provided projecting in the first direction from the end of the extending arm 1320. The extending arm pushing portion 1326 may be provided to have a width relatively smaller than that of the extending arm 1320. The extending arm pushing portion 1326 may be positioned on the central side of the end of the extending arm 1320, or it may be positioned eccentrically to one side from the central side of the end of the extending arm 1320. The extending arm pushing portion 1326 may be positioned in a region that overlaps with the sensor unit carrier body 1310 in the second direction. A fixing projection 1317 projecting from one end of the sensor unit carrier body 1310 may be positioned to protrude further than the extending arm pushing portion 1326. When the sensor unit carrier 130 moves along the first direction to the insertion position, the extending arm pushing portion 1326 may be positioned to pressurize a pressed portion 1165 provided on the transmitting unit support hook 1162. When the extended arm pushing portion 1326 pressurizes the pushing portion 1165, the transmitting unit support hook 1162 deforms outward away from the transmitting unit 40, thereby releasing the restriction on the movement of the transmitting unit 40 by the locking portion 1164.

[0205] The inclined surface 1326a formed on the extended arm pushing portion 1326 and the inclined surface 1165a formed on the pressed portion 1165 are not particularly limited as long as they are shaped to deform outward, away from the transmitting unit support hook 1162, when the pressed portion 1165 is pressurized by the extended arm pushing portion 1326. For example, the extended arm pushing portion 1326 may be provided in a shape in which the cross-section decreases along the first direction, and the inclined surface 1326a of the extended arm pushing portion 1326 may be formed at a position facing the inner side wall of the body housing body portion 1100. One end of the pressed portion 1165 is provided with an inclined surface 1165a corresponding to the inclined surface 1326a of the extended arm pushing portion 1326, and the inclined surface 1165a of the pressed portion 1165 may be formed to be inclined in the opposite direction to the inclined surface 1326a of the extended arm pushing portion 1326 with respect to the first direction. It is preferable that the extended arm pushing portion 1326 is formed in a position where it can pressurize the pushed portion 1165 at the same time as the sensor unit carrier 130 reaches the insertion position, or immediately before the sensor unit carrier 130 reaches the insertion position.

[0206] A sensor unit carrier ring portion 1316, on which an elastic member 150 (described later) is fixedly positioned, may be provided at one end of the second movable space 1312 adjacent to the handle housing 120. The sensor unit carrier ring portion 1316 may be positioned opposite the fourth opening 1314, or it may be positioned inside the second movable space 1312. On the other hand, a fixing groove 1340, shaped to correspond to the fixing projection 1137, may be recessed on one surface of the sensor unit carrier body 1310 opposite to the second movable space 1312. When the sensor unit carrier 130 is in its initial position, it is preferable that the fixing groove 1340 is recessed at a position corresponding to the fixing projection 1137.

[0207] Needle carrier Figure 24 is a perspective view illustrating the coupling relationship of the needle carrier 140, Figure 25 is a perspective view showing an exemplary embodiment of the needle carrier 140, and Figure 26 is a front view illustrating the coupling relationship between the needle carrier 140 and the sensor unit carrier 130.

[0208] The needle carrier 140 may be provided with a needle 1401 for subcutaneous insertion of the transcutaneous sensor member 330, and move along a first direction together with the sensor unit carrier 130 and the sensor unit 30, and after subcutaneous insertion of the transcutaneous sensor member 330, move in the opposite direction to the first direction in a second movement space 1312 to remove the needle body 1402 from the subcutaneous tissue.

[0209] The needle carrier 140 may include a needle 1401 and a needle carrier body 1410. The needle carrier body 1410 may be capable of fixing the needle 1401 and may be configured to move together with the needle 1401. The needle 1401 may include a needle body 1402, one end of which is inserted subcutaneously for subcutaneous insertion of the transcutaneous sensor member 330, and a needle holder 1403 for fixing the needle body 1402. The needle body 1402 has an opening that opens radially outward with respect to the extending direction of the needle body 1402, and the opening may extend along a first direction. The needle body 1402 may have one end adjacent to the transmitting unit housing 1104 open. The one end of the needle body 1402 adjacent to the transmitting unit housing 1104 may be formed to be inclined.

[0210] A needle holder insertion groove 1412 may be recessed at one end of the needle carrier body 1410 facing the fourth opening 1314, into which a needle holder 1403 is inserted and fixed. By inserting and fixing the needle holder 1403 into the needle holder insertion groove 1412, the needle 1401 can be fixed to the needle carrier body 1410.

[0211] When the needle carrier 140 is in the initial and insertion positions, the needle body 1402 is discharged to the outside through the fourth opening 1314, and when the needle carrier 140 returns to the retracted position, the needle body 1402 flows in through the fourth opening 1314 and may be positioned inside the second moving space 1312.

[0212] A needle guide groove 1415 may be provided on one side of the needle carrier body 1410, having a shape that recesses from that side and extends along the first direction. The needle guide groove 1415 may be provided in a shape that extends from the tip to the end of the needle carrier body 1410 so as to terminate at one side of the needle carrier body 1410. The tip of the aforementioned needle carrier guide projection 1313 may be positioned inside the needle guide groove 1415. The interaction between the needle carrier guide projection 1313 and the needle guide groove 1415 can guide the movement of the needle carrier 140 in a direction opposite to the first direction. The needle guide groove 1415 may be recessed in pairs symmetrically on both ends of the needle carrier body 1410.

[0213] The needle carrier wing bodies 1430 may be provided in pairs, extending from both ends of the needle carrier body 1410 in a direction opposite to the first direction. The needle carrier wing bodies 1430 may be positioned extending from both ends of the needle carrier body 1410, where the needle guide grooves 1415 are formed. The needle guide grooves 1415 and needle holder insertion grooves 1412 may be positioned on opposing surfaces of the needle carrier wing body 1430, respectively, and may be positioned so as not to overlap with each other in the first direction. The needle carrier wing bodies 1430 may be provided to deform when an external force is applied and to return to their original state after the external force is removed. Needle carrier latches 1434 and triggers 1432 may be provided at the tip of the needle carrier wing body 1430. The needle carrier latches 1434 and triggers 1432 may be positioned so as not to overlap with the needle carrier body 1410 in the first direction. The needle carrier latch 1434 may include a restraining surface 1434b formed in a direction substantially parallel to the second direction, and an inclined surface 1434a that is inclined to move toward the needle carrier wing body 1430 side toward the first direction from one end of the protruding restraining surface 1434b. The restraining surface 1434b and the inclined surface 1434a may be arranged sequentially toward the first direction.

[0214] The trigger 1432 may be provided in a shape that protrudes outward from the needle carrier latch 1434 and occupies a larger area. The trigger 1432 may be provided with a trigger inclined portion 1433 such that the cross-section of the trigger 1432 decreases along the first direction. The trigger inclined portion 1433 may be provided at a position further away in the first direction than the inclined surface 1434a, and the trigger inclined portion 1433 and the inclined surface 1434a may be provided at positions that do not overlap in the first direction. It is preferable that the trigger 1432 is located outside the second movement space 1312.

[0215] Before the applicator assembly 1 is activated, or when the needle carrier 140 moves along the first direction, the restraining surface 1434b of the needle carrier latch 1434 maintains contact with the detent restraining surface 1318b of the sensor unit carrier detent 1318, thereby restricting the relative movement of the needle carrier 140 with respect to the sensor unit carrier 130. In other words, when the restraining surface 1434b of the needle carrier latch 1434 is in contact with the detent restraining surface 1318b of the sensor unit carrier detent 1318, the needle carrier 140 cannot move independently, and the needle carrier 140 can only move together with the sensor unit carrier 130 when the sensor unit carrier 130 moves while restrained by it.

[0216] During the subcutaneous insertion process of the transcutaneous sensor member 330, when the needle carrier 140 moves to a position adjacent to the insertion position, the trigger inclined portion 1433 of the trigger 1432 comes into contact with the tip of the partition wall 1112, causing the needle carrier wing body 1430 to deform inward into the second movement space 1312. As the needle carrier wing body 1430 deforms inward into the second movement space 1312, the restraining surface 1434b of the needle carrier latch 1434 can release its contact restraint with the detent restraining surface 1318b of the sensor unit carrier detent 1318.

[0217] As the restraining surface of the needle carrier latch 1434 is released from contact with the detent restraining surface 1318b of the sensor unit carrier detent 1318, the needle carrier latch 1434 can move over the sensor unit carrier detent 1318, and the elastic force applied from the elastic member 150 allows the needle carrier 140 to move in the opposite direction to the first direction and reach the retracted position.

[0218] To achieve objectives such as preventing pain caused by excessive insertion of the needle body 1402 into body B, it is preferable that the constraint on the movement of the sensor unit carrier 130 relative to the needle carrier 140 is released before the sensor unit carrier 130 reaches the insertion position. In this case, even if the needle carrier 140 moves in a direction opposite to the first direction, the sensor unit carrier 130 maintains a state in which it is pressurizing the sensor unit 30 toward the first direction, and the transcutaneous sensor member 330 can be accurately inserted into the target subcutaneous position due to the inherent rigidity of the transcutaneous sensor member 330.

[0219] Multiple grip arms 1422 may be provided in a shape that extends along a first direction from the other two ends of the needle carrier body 1410. That is, multiple grip arms 1422 may extend from one side of the needle carrier body 1410 adjacent to the side of the needle carrier body 1410 in which the needle guide groove 1415 is formed. Multiple grip arms 1422 may also be provided on the needle carrier body 1410 in pairs in a symmetrical shape. The tip of each grip arm 1422 is provided with a grip portion 1423 that protrudes inward, and the side end of the sensor unit housing 310 may be gripped by the grip portion 1423. The grip arms 1422 may be formed in a shape that extends beyond the needle holder insertion groove 1412, and the grip portion 1423 may be positioned so as not to overlap with the needle carrier body 1410 in a second direction. The grip arm projection 1424 may be formed to protrude from one side of the grip arm 1422 facing the partition wall of the column 1110. The grip arm protrusions 1424 may be provided on each grip arm 1422, or they may be provided in a region that overlaps with the needle carrier body 1410 in the second direction.

[0220] When the needle carrier 140 is in its initial position, the grip arm projection 1424 can be positioned inside the grip arm guide groove 1120 before passing the first stepped inclined surface 1123, or it can pass the first stepped inclined surface 1123 and maintain a state of close contact and pressure by the stepped portion 1121. During the subcutaneous insertion process of the transcutaneous sensor member 330, the grip arm projection 1424 passes the second stepped inclined surface 1124, the close contact and pressure on the grip arm projection 1424 by the stepped portion 1121 is released, and the sensor unit 30 can be transmitted to the transmission unit 40 with each grip arm 1422 slightly spread outwards.

[0221] A needle carrier ring portion 1414 is provided at one end of the needle carrier body 1410 facing the sensor unit carrier ring portion 1316, and the other end of the elastic member 150, one end of which is connected to the sensor unit carrier ring portion 1316, may be connected to the needle carrier ring portion 1414. The needle carrier ring portion 1414 may protrude from the center of the needle carrier body 1410 and may protrude to a lower height than the needle carrier wing body 1430.

[0222] The elastic member 150 can be any means capable of providing a driving force to move the needle carrier 140 in a direction opposite to the first direction, but a tension spring is preferably used.

[0223] cap Figure 27 is an exploded perspective view showing an exemplary embodiment of the cap 50, and Figure 28 is a cross-sectional view of the cap 50 cut along the E-E' direction in Figure 27. Figures 29 to 31 are partially enlarged cross-sectional views showing exemplary embodiments of the applicator assembly 1 to which the cap 50 is applied.

[0224] The cap 50 may be fixedly positioned on one end of the applicator 10 in a releasable manner. Since the applicator assembly 1 includes the cap 50, it can effectively prevent any unintended ejection of the applicator 10 or the inflow of external contaminants or moisture into the applicator assembly 1, which may occur during the manufacturing, distribution, storage, and use of the applicator assembly 1.

[0225] The cap 50 may include a cap housing 501 that forms the outer shape of the cap 50. Inside the cap housing 501, a housing space 503 may be formed that communicates with the outside through a fifth opening 502 formed at one end of the cap housing 501. The inner surface 501a' at one end of the cap housing 501 where the fifth opening 502 is formed may be provided with a threaded portion 540 that corresponds to the threaded portion 1240 formed on the handle housing 120.

[0226] The cap 50 can be detachably screw-connected to one end of the handle housing 120 by screw-connecting the threaded portion 1240 formed on the handle housing 120 with the threaded portion 540 formed on the cap housing 501.

[0227] A first joint 501a and a second joint 501c may be provided at the end of the cap housing 501 where the fifth opening 502 is formed. A threaded portion 540 may be formed on the inner surface 501a' of the first joint 501a. The second joint 501c may be positioned inside the first joint 501a and substantially parallel to the first joint 501a. The end of the second joint 501c may be positioned further inside the housing space 503 compared to the end of the first joint 501a.

[0228] On one surface of the second joint 501c facing the inner surface 501a' of the first joint 501a, a protruding portion 501c' that rounds toward the first joint 501a may be provided, extending along the circumferential direction of the second joint 501c. The second joint 501c may be formed of the same material as the first joint 501a, but it may also be formed of a material with better elasticity or stretchability than the first joint 501a.

[0229] As shown in Figures 30 and 31, when the cap 50 is coupled to the handle housing 120, the end of the handle housing 120 may be positioned in the coupling space 501b between the first coupling portion 501a and the second coupling portion 501c. In this case, the protruding portion 501c' will be in close contact with the contact surface 1203 on the inside of the handle housing 120, thereby sealing the coupling portion between the handle housing 120 and the cap 50.

[0230] The outer surface of the cap housing 501 may have a plurality of grip grooves 505 recessed to facilitate the work or use of the operator or user. The plurality of grip grooves 505 may be formed in a shape that extends along a first direction, and each grip groove 505 may be spaced apart from one another at regular intervals. The number and shape of the grip grooves 505 are not limited to those shown in the drawings, and the number and shape of the grip grooves 505 can be modified in various ways.

[0231] On the other hand, although the drawing shows a cup-shaped cap housing 501, the shape of the cap housing 501 of the present invention is not necessarily limited to this. The shape of the cap housing 501 can be modified in various ways as long as it is a shape that can protect and dehumidify the inside of the applicator 10. The cap housing 501 may also be a means for protecting and dehumidifying the inside of the applicator 10. However, since one end of the cap housing 501 on which the threaded portion 540 is formed is intended to be screw-connected to the threaded portion 1240 formed on the handle housing 120, it is preferable that the end of the cap housing 501 on which the threaded portion 540 is formed is provided in a cylindrical shape corresponding to the end of the handle housing 120.

[0232] A concave housing groove 504 may be provided at the closed other end of the cap housing 501 facing the fifth opening 502, extending from the outside toward the housing space 503. Multiple vents 507 connecting the housing groove 504 and the housing space 503 may be formed through the other end of the cap housing 501 that forms the housing groove 504. A first sealing member 510, a desiccant 512, and a second sealing member 514 may be arranged in order in the housing groove 504, moving outward from one side of the vents 507.

[0233] The first sealing member 510 is preferably manufactured using a material that is permeable to air but impermeable to moisture, and as a non-limiting example, DuPont's Tyvek material can be used. The first sealing member 510 effectively prevents moisture from entering the containment space 503.

[0234] The desiccant 512 is preferably manufactured using a material that has a dehumidifying function applicable to electronic devices or medical devices. The desiccant 512 can remove moisture that has entered the containment space 503.

[0235] The second sealing member 514 is positioned to seal the housing groove 504 from the outside and may be manufactured using a material that prevents the permeation of moisture and external sources of contamination. In a non-limiting example, the second sealing member 514 may be manufactured using aluminum packaging paper.

[0236] Because the ventilation opening 507 allows the first sealing member 510, the desiccant 512, and the second sealing member 514 to be arranged in order within the containment groove 504 which communicates with the containment space 503, not only can moisture that has flowed into the containment space 503 be effectively removed, but contaminants or moisture from the outside can also be effectively prevented from flowing into the containment space 503.

[0237] During the manufacturing of the applicator assembly 1, the first sealing member 510 can be attached to the housing groove 504 with the handle housing 120 and cap 50 joined together, and then the inside of the applicator assembly 1 can be sterilized. After sterilization, a desiccant 512 can be placed in the housing groove 504, and the second sealing member 514 can be fused to the end of the housing groove 504 where the desiccant 512 is placed, thereby sequentially performing internal sterilization and dehumidification of the applicator assembly 1. Unlike cases where the applicator assembly 1 is placed in a separate packaging material or packaging container before sterilization and dehumidification, sterilization and dehumidification are performed during the assembly process of the applicator assembly 1, thus simplifying the manufacturing process of the applicator assembly 1.

[0238] On the other hand, the sensor unit 30 and the transmitting unit 40 remain separated before subcutaneous insertion of the sensor member 330, and the sensor unit 30 and the needle 1401 remain positioned inside the applicator 10. Therefore, the end of the sensor member 330 or the needle 1401 does not extend to the housing groove 504 of the cap 50. Thus, by simplifying the sterilization and dehumidification structure, the structure of the cap 50 can be simplified, and by simplifying the structure of the cap 50, the applicator assembly 1 to which the cap 50 is attached can have a compact size.

[0239] As shown in Figure 31, a pair of ring-shaped sealing members 508a and 508b may be provided at the tip of the cap housing 501, and a caulking member 1243 may be provided protruding from one surface of a locking projection 1242 corresponding to the tip of the cap housing 501. When the threaded portion 540 formed on the cap housing 501 and the threaded portion 1240 formed on the handle housing 120 are screw-connected to each other, and the cap 50 is connected to one end of the handle housing 120, the sealing members 508a and 508b tightly pressurize the caulking member 1243, effectively preventing external contaminants or moisture from flowing into the space between the handle housing 120 and the cap 50.

[0240] The caulking member 1243 and the sealing members 508a and 508b may be injection molded integrally with the handle housing 120 and the cap housing 501, or they may be manufactured separately using a self-elastic material such as rubber or silicone. Even when the caulking member 1243 and the sealing members 508a and 508b are injection molded integrally with the handle housing 120 and the cap housing 501, the caulking member 1243 and the sealing members 508a and 508b may be injection molded from different materials distinct from the handle housing 120 and the cap housing 501.

[0241] The assembly and operation processes of the applicator 10 and applicator assembly 1 will be described in more detail below with reference to Figures 32 to 49.

[0242] Exemplary Embodiments of the Function of the Fixing Part Figure 32 is a partial cross-sectional view showing an exemplary embodiment of the applicator assembly 1 in which the sensor unit carrier 130 is connected to the body housing 110 during the assembly process. Figures 33 and 34 are partial cross-sectional views showing exemplary embodiments of the process of connecting the handle housing 120 to the body housing 110 to which the sensor unit carrier 130 is connected during the assembly process of the applicator assembly 1. Figure 35 is an enlarged cross-sectional view showing an exemplary embodiment of the applicator assembly 1 in which the tip of the fixed projection 1137 is inserted into the fixed groove 1340 during the assembly process of the applicator assembly 1. Figure 36 is an enlarged cross-sectional view showing an exemplary embodiment of the applicator assembly 1 in which the tip of the fixed projection 1137 is ejected from the fixed groove 1340 during the assembly process of the applicator assembly 1.

[0243] As shown in Figures 32 and 35, during the assembly process of the body housing 110 and the sensor unit carrier 130, the sensor unit carrier body 1310 may be inserted into the column 1110 that forms the first moving space 1111. During the insertion of the sensor unit carrier body 1310 into the column 1110, the fixed projection 1137 contacts one surface of the sensor unit carrier body 1310, and the support base 1134 can maintain an outwardly deformed state. As the sensor unit carrier body 1310 moves along the first direction, the support base 1134 maintains its outwardly deformed state, and as the fixed groove 1340 formed in the sensor unit carrier body 1310 reaches a position corresponding to the fixed projection 1137, the support base 1134 can recover from its deformed state to its original state. That is, as the tip of the fixed projection 1137 flows into the fixed groove 1340, the pressurized moving part 1131 moves toward the sensor unit carrier body 1310, and the support base 1134 can also recover from its deformation.

[0244] The tip of the fixed projection 1137 flows into the fixed groove 1340, thereby restricting the movement of the sensor unit carrier 130 in the first direction. During the assembly process of the applicator assembly 1, the worker can recognize that the tip of the fixed projection 1137 has properly flowed into the fixed groove 1340 by the sound of parts colliding or by the sensation transmitted to their fingertips.

[0245] Multiple fixing portions 1130 may be provided, or multiple fixing protrusions 1137 may be provided on one fixing portion 1130, and the fixing groove 1340 may be recessed on one surface of the sensor unit carrier body 1310 in a corresponding shape and number. To reduce friction during the process of at least one end of the fixing protrusion 1137 flowing into and out of the fixing groove 1340, the fixing groove 1340 and / or the fixing protrusion 1137 may be provided with an inclined surface. The fixing groove 1340 may be formed not only as a recess on one surface of the sensor unit carrier body 1310, but also to penetrate one surface of the sensor unit carrier body 1310.

[0246] Subsequently, the worker can perform the task of attaching the handle housing 120 to the body housing 110 to which the sensor unit carrier 130 is attached. When attaching the handle housing 120 to the body housing 110 to which the sensor unit carrier 130 is attached, the sensor unit carrier 130 may be pressurized by the handle housing 120 that enters for assembly, which may cause arbitrary ejection or displacement of the sensor unit carrier 130 from its initial position.

[0247] When assembling the handle housing 120 with the tip of the fixed projection 1137 flowing into the fixed groove 1340, it is possible to effectively prevent arbitrary ejection of the applicator 10 or displacement of the sensor unit carrier 130.

[0248] As shown in Figures 33, 34, and 36, during the process of connecting the handle housing 120 to the body housing 110 to which the sensor unit carrier 130 is attached, the tip of the push arm 1230 provided on the handle housing 120 moves to a position where it contacts the pressurizing inclined surface 1133a of the pressurizing moving wing portion 1133. As the handle housing 120 is assembled, the tip of the push arm 1230 moves in a first direction while in contact with the pressurizing inclined surface 1133a, pressurizing the pressurizing moving wing portion 1133, causing the support base 1134 to deform outward and the pressurizing moving portion 1131 to be pushed away from the sensor unit carrier body 1310. As the pressurizing moving portion 1131 is pushed away from the sensor unit carrier body 1310, the tip of the fixed projection 1137 can be discharged from the fixed groove 1340. As the tip of the fixed projection 1137 is discharged from the fixed groove 1340, the restriction on arbitrary movement of the sensor unit carrier 130 by the fixed part 1130 is released, and the sensor unit carrier 130 can maintain a state in which it can move regardless of the fixed part 1130.

[0249] Figure 34 shows the state in which the tip of the sensor unit carrier 130 is in complete contact with the inner surface of the handle housing 120 after the applicator 10 has been assembled. However, even after the applicator 10 has been assembled, the tip of the sensor unit carrier 130 may remain at a certain distance from the inner surface of the handle housing 120, as shown in Figure 33. In this case, during the process in which the user pressurizes the handle housing 120 and the handle housing 120 moves from the first position to the second position, the distance between the tip of the sensor unit carrier 130 and the handle housing 120 may be maintained or narrowed. If excessive pressure is applied to the handle housing 120 during the operation of the applicator assembly 1, a buffer can be provided to prevent that pressure from being directly transmitted to the percutaneous sensor member 330.

[0250] Exemplary Embodiments for the Operation of a Needle Carrier Figures 37 to 39 are partial cross-sectional views sequentially showing exemplary embodiments of the operation of the applicator assembly 1, in which the sensor unit carrier 130 moves from its initial position to the insertion position, and Figure 40 is a partial cross-sectional view showing exemplary embodiments of the operation of the applicator assembly 1, in which the needle carrier 140 moves to the retracted position.

[0251] As shown in Figure 37, as the sensor unit carrier 130 moves from its initial position toward the insertion position, the restraining surface 1434b of the needle carrier latch 1434 maintains contact with the detent restraining surface 1318b of the sensor unit carrier detent 1318. This allows the needle carrier 140 to remain restrained to the sensor unit carrier 130 and move together with the sensor unit carrier 130 along the first direction.

[0252] As shown in Figure 38, when the sensor unit carrier 130 reaches the insertion position or a position adjacent to the insertion position, the trigger inclined portion 1433 of the trigger 1432 may come into contact with the tip of the partition wall 1112. On the other hand, as shown in Figure 39, as the sensor unit carrier 130 continues to move in the first direction, the needle carrier wing body 1430 deforms inward into the second movement space 1312, thereby allowing the restraining surface 1434b of the needle carrier latch 1434 and the detent restraining surface 1318b of the sensor unit carrier detent 1318 to shift away from the position where they are in contact with each other. Therefore, the needle carrier latch 1434 is released from the restraint of the sensor unit carrier detent 1318, and the needle carrier 140 becomes able to move relative to the sensor unit carrier 130.

[0253] On the other hand, as shown in Figures 38 and 39, the release of the movement constraint of the needle carrier 140 by the sensor unit carrier 130 may be performed before the sensor unit carrier 130 reaches the insertion position, thereby effectively preventing the occurrence of side effects due to excessive insertion of the needle body 1402 into body B. That is, the release of the movement constraint of the needle carrier 140 by the sensor unit carrier 130 can be performed not only when the tip of the grip arm 1422 is in contact with one end of the transmitting unit 40, but also when the tip of the grip arm 1422 is slightly separated from one end of the transmitting unit 40. When the movement constraint of the needle carrier 140 by the sensor unit carrier 130 is released, the needle carrier 140 can move in the direction opposite to the first direction by the elastic force of the elastic member 150.

[0254] When the movement constraint on the needle carrier 140 by the sensor unit carrier 130 is released while the tip of the grip arm 1422 is slightly separated from one end of the transmitting unit 40, the risk of malfunction or coupling failure that may occur due to the grip arm 1422 colliding with or coming into contact with the transmitting unit 40 can be effectively reduced.

[0255] As shown in FIG. 40, after the restraint of the needle carrier latch 1434 by the sensor unit carrier detent 1318 is released, the needle carrier 140 can move relative to the sensor unit carrier 130. The needle carrier 140 can move in a direction opposite to the first direction by the driving force applied from the elastic member 150 and reach the retracted position.

[0256] When the needle carrier 140 reaches the retracted position, the tip of the needle body 1402 is arranged to be completely accommodated within the first movement space 1111, so that the needle body 1402 can be maintained in a state where it is not exposed or protruding outside the applicator 10 any further. <(

[0257] Exemplary Embodiments of Bridge Action FIG. 41 is a partial cross-sectional view showing an exemplary embodiment of the state before the bridge 1330 is cut in the operating process of the applicator assembly 1, and FIG. 42 is a partial cross-sectional view showing an exemplary embodiment of the state where the bridge 1330 is cut in the operating process of the applicator assembly 1.

[0258] FIG. 41 is a diagram for explaining the positional relationship between the bridge 1330 and the bridge pressing portion 1116 when the sensor unit carrier 130 is located at the initial position. As shown in FIG. 41, not only when the bridge 1330 is arranged at a position spaced apart from the bridge pressing portion 1116 by a certain interval at the initial position, but also when the tip of the bridge pressing portion 1116 abuts against the bridge 1330 at the initial position may be included.

[0259] When the handle housing 120 is pressed and moved in a first direction by the user, the sensor unit carrier 130 can also move along the handle housing 120 in the first direction. The bridge 1330 will break only when a force greater than the breaking strength of the bridge 1330 designed during the manufacturing process is applied to the handle housing 120, as shown in Figure 42, and only when the bridge 1330 breaks can the normal injection and subcutaneous insertion of the transcutaneous sensor member 330 occur.

[0260] Figure 42 illustrates an example where the bridge 1330 breaks at the weak point 1332, but it may also include cases where the bridge 1330 breaks in a region other than the weak point 1332.

[0261] Multiple weak points 1332 may be provided, and the bridge pressurizing section 1116 may be positioned to face the weak points 1332 or the region between multiple weak points 1332. Of the multiple weak points 1332, those weak points relatively adjacent to the sensor unit carrier body 1310 may break, and those weak points relatively far from the sensor unit carrier body 1310 may be partially broken and bent. The bridge pressurizing section 1116 may be positioned to face the region between the multiple weak points 1332 that is relatively adjacent to the sensor unit carrier body 1310.

[0262] Multiple vulnerable portions 1332 may have the same thickness or may have different thicknesses. A vulnerable portion 1332 that is relatively adjacent to the sensor unit carrier body 1310, or a vulnerable portion 1332 that is relatively adjacent to the contact portion with the bridge pressurizing portion 1116, may be thinner than other vulnerable portions 1332.

[0263] Exemplary Embodiments of the Interaction between the First Movement Restriction Unit and the Second Movement Restriction Unit Figure 43 is a cross-sectional view and a partially enlarged cross-sectional view illustrating an exemplary embodiment of the positional relationship between the first movement limiting portion 1220 and the second movement limiting portion 1150 in the state before operation of the applicator assembly 1, and Figures 44(a) to (c) are partially enlarged cross-sectional views sequentially illustrating an exemplary embodiment of the positional relationship between the first movement limiting portion 1220 and the second movement limiting portion 1150 during the operation process of the applicator assembly 1.

[0264] As shown in Figures 43 and 44(a), in the pre-operation state of the applicator assembly 1, the support surface 1222 of the first movement limiting part 1220 and the first support surface 1153b of the first movement limiting latch 1152 may be positioned to face each other. Therefore, even if a force is applied to the handle housing 120 in a direction opposite to the first direction, the support surface 1222 of the first movement limiting part 1220 and the first support surface 1153b of the first movement limiting latch 1152 will contact and support each other, preventing the handle housing 120 from moving any further in the direction opposite to the first direction. This effectively prevents the handle housing 120 from detaching from the body housing 110 at will.

[0265] On the other hand, as shown in Figures 44(b) and (c), during the injection process of the applicator assembly 1, the first movement limiting unit 1220 can move toward the second movement limiting latch 1154.

[0266] As the handle housing 120 moves in the first direction, the inclined surface 1221 of the first movement limiting portion 1220 moves to a position adjacent to the second inclined surface 1155a of the second movement limiting latch 1154. Subsequently, the handle housing 120 moves further in the first direction with the inclined surface 1221 of the first movement limiting portion 1220 and the second inclined surface 1155a of the second movement limiting latch 1154 in contact. The other end of the movement limiting body 1151 deforms toward the second internal space 1102, allowing the first movement limiting portion 1220 to move so as to pass through the second movement limiting latch 1154.

[0267] The above example describes the case in which the other end of the movement-restricting body 1151 deforms toward the second internal space 1102 during the movement of the handle housing 120. However, depending on the material or thickness of the handle housing 120 and the body connection part 1157, the main body that deforms and moves can be deformed in various ways and applied accordingly.

[0268] After the first movement-restricting section 1220 passes the second movement-restricting latch 1154, the movement-restricting body 1151 returns to its pre-deformation state, and the support surface 1222 of the first movement-restricting section 1220 and the second support surface 1155b of the second movement-restricting latch 1154 are placed facing each other. The interaction between the support surface 1222 of the first movement-restricting section 1220 and the second support surface 1155b of the second movement-restricting latch 1154 restricts the handle housing 120 from moving in the direction opposite to the first direction, thereby strictly limiting the reuse of the applicator 10 after the injection of the transcutaneous sensor member 330.

[0269] Exemplary Embodiment of the Action of the Grip Arm Protrusion Figures 45 to 47 are cross-sectional views illustrating exemplary embodiments of pressurization and depressurization of the grip arm projection 1424 during the operation of the applicator assembly 1.

[0270] Figure 45 shows the applicator assembly 1 in its pre-operation state, and the grip arm projection 1424 may be positioned so as not to pass through the first stepped inclined surface 1123. That is, in order to maintain a state in which the grip arm projection 1424 is not pressurized by the stepped portion 1121, the grip arm 1422 can grip the sensor unit 30 in a slightly loose state.

[0271] On the other hand, unlike in Figure 45, the grip arm projection 1424 may be positioned in a state where it has passed the first stepped inclined surface 1123 before the applicator assembly 1 is activated. In this case, the grip arm projection 1424 is pressurized by the stepped portion 1121, and the grip arm 1422 can maintain a firm grip on the sensor unit 30.

[0272] When the handle housing 120 is pressed in the first direction by the user, the grip arm projection 1424 can move in the first direction while maintaining pressure on the stepped portion 1121, as shown in Figure 46. During this process, the sensor unit 30 can move toward the transmitting unit 40 while maintaining a firm grip on the grip arm 1422.

[0273] Subsequently, as shown in Figure 47, the grip arm projection 1424 passes through the second stepped inclined surface 1124, releasing the pressure on the grip arm projection 1424 caused by the stepped portion 1121. The grip arm 1422 can then grasp the sensor unit 30 in a slightly loose state and transmit the sensor unit 30 to the transmitting unit 40. The sensor unit 30 may be transmitted to the transmitting unit 40 at the same time that the grip arm projection 1424 passes through the second stepped inclined surface 1124, but it is more preferable that the sensor unit 30 is transmitted to the transmitting unit 40 after the grip arm projection 1424 has passed through the second stepped inclined surface 1124.

[0274] While the needle carrier latch 1434 may be released by the sensor unit carrier detent 1318 at the same time that the grip arm projection 1424 passes the second stepped inclined surface 1124, it is more preferable, from the viewpoint of accurate transmission of the sensor unit 30, that the needle carrier latch 1434 be released by the sensor unit carrier detent 1318 immediately after the grip arm projection 1424 passes the second stepped inclined surface 1124, as shown in Figure 39.

[0275] During the subcutaneous insertion process of the transcutaneous sensor member 330, since the sensor unit 30 is continuously transmitted with a force in the first direction by the sensor unit housing 310, even if the grip arm 1422 holds the sensor unit 30 in a slightly loose state and transmits the sensor unit 30 to the transmission unit 40, the sensor unit 30 can be accurately transmitted to the seating groove 412. Because the grip arm 1422 holds the sensor unit 30 in a slightly loose state and transmits the sensor unit 30 to the seating groove 412 of the transmission unit 40, during the process of the needle carrier 140 returning to the retracted position, it is possible to effectively prevent the operation error caused by the sensor unit 30 being dragged by the needle carrier 140.

[0276] Exemplary Embodiments for the Operation of the Transmitter Unit Support FIGS. 48 and 49 are cross-sectional views sequentially shown to illustrate exemplary embodiments of the movement restraint and release of the transmission unit 40 by the transmission unit support 1160 during the operation of the applicator assembly 1.

[0277] As shown in FIG. 48, in the state before the operation of the applicator assembly 1, by disposing the tip of the locking portion 1164 provided on the transmission unit support hook 1162 inside the transmission unit housing groove 417 of the transmission unit housing 410, it is possible to effectively prevent the transmission unit 40 from arbitrarily detaching from the transmission unit accommodation portion 1104. In this case, the sensor unit carrier 130 is located at the initial position, and the extending arm pressing portion 1326 provided on the sensor unit carrier 130 located at the initial position can maintain a state separated from the pressed portion 1165 of the transmission unit support hook 1162.

[0278] Before the operation of the applicator assembly 1 or during the subcutaneous insertion process of the transcutaneous sensor member 330, since the transmission unit support hook 1162 can prevent the transmission unit 40 from arbitrarily detaching from the transmission unit accommodation portion 1104, the economy and operation accuracy of the applicator assembly 1 can be effectively improved.

[0279] On the other hand, as shown in Figure 49, when the applicator assembly 1 is activated and the sensor unit carrier 130 moves to the insertion position, the extended arm pushing portion 1326 presses against the inclined surface 1165a formed on the pushed portion 1165, causing the transmitting unit support hook 1162 to deform and move away from the transmitting unit 40. As a result, the tip of the locking portion 1164 detaches from the transmitting unit housing groove 417, thereby releasing the movement constraint on the transmitting unit 40 imposed by the transmitting unit support hook 1162. In other words, when the sensor unit carrier 130 is in its initial position, the transmitting unit support portion 1160, located in the movement constraint position, restricts the arbitrary detachment of the transmitting unit 40. When the sensor unit carrier 130 switches to the insertion position, the transmitting unit support portion 1160 switches to the release position, thereby releasing the restriction on the arbitrary detachment of the transmitting unit 40 imposed by the transmitting unit support portion 1160.

[0280] The transmitting unit support portion 1160, through interaction with the extended arm pushing portion 1326, releases the movement constraint of the transmitting unit 40 by the transmitting unit support hook 1162 during the process in which the transcutaneous sensor member 330 is inserted subcutaneously. Therefore, during the process of separating the applicator 10 and the wearable unit 20 after the subcutaneous insertion of the transcutaneous sensor member 330 is complete, the wearable unit 20 can be effectively prevented from being pulled along by the applicator 10.

[0281] On the other hand, the applicator assembly 1 may also include cases where the pressed portion 1165 and the extended arm pressing portion 1326 are not provided. In the state before operation of the applicator assembly 1, at least one end of the tip of the locking portion 1164 is positioned inside the transmitting unit housing groove 417, thereby preventing the transmitting unit 40 from being arbitrarily detached from the transmitting unit housing portion 1104.

[0282] During the process of separating the applicator 10 from the skin after subcutaneous insertion of the transcutaneous sensor member 330, the adhesive force of the first adhesive surface allows the transmitting unit support portion 1160 to move away from the transmitting unit 40.

[0283] Although the present invention has been described in detail above with reference to embodiments, other forms of embodiments are also possible. Therefore, the technical idea and scope of the claims described below are not limited to these embodiments. [Explanation of symbols]
