Applicator and applicator assembly

Abstract

According to one aspect of the present invention, an applicator and an applicator assembly can be provided that can stably attach a wearable unit to the skin while inserting a percutaneous sensor into an accurate subcutaneous position.

Description

Technical Field

[0001] The present invention relates to an applicator and applicator assembly, and more particularly, to an applicator and applicator assembly for inserting a transdermal sensor for detecting biological information under the skin. Background Technology

[0002] Chronic diseases such as diabetes require continuous management. Early-stage diabetes is often asymptomatic, but as the disease progresses, characteristic symptoms appear, such as excessive thirst, increased appetite, frequent urination, weight loss, general fatigue, itchy skin, and slow-healing wounds on the hands and feet. Further progression of diabetes can lead to complications such as vision impairment, high blood pressure, kidney disease, stroke, periodontal disease, muscle cramps and neuralgia, and gangrene. Systematic blood glucose monitoring and treatment are essential for diagnosing and managing diabetes to prevent complications.

[0003] People with diabetes, or those who do not yet have diabetes but whose blood sugar is too high, need to measure their blood sugar continuously and periodically in order to manage their diabetes or prevent it from developing into diabetes.

[0004] Currently, the mainstream method for measuring blood glucose is blood sampling, which involves collecting blood from a site such as a fingertip and measuring blood glucose in a single measurement. However, the pain and discomfort associated with blood sampling limit this method for continuous and periodic blood glucose monitoring.

[0005] In recent years, to overcome the limitations of blood sampling methods for measuring blood glucose, a blood glucose measurement system that continuously and periodically measures blood glucose by inserting a transcutaneous sensor under the skin has been developed and put into use. Blood glucose measurement systems using transcutaneous sensors are typically arranged to include: a wearable unit that includes a transcutaneous sensor and is configured to attach to the body; an applicator configured to be pre-connected to the wearable unit to insert the transcutaneous sensor under the skin while attaching the wearable unit to the body; and a receiving unit for processing information received from the wearable unit.

[0006] Furthermore, for hygiene and infection prevention reasons, wearable units are typically designed to be discarded after a single use, and applicators are also typically designed to be discarded after a single trigger. In other words, if the transcutaneous sensor is not inserted into the correct subcutaneous position, or the wearable unit is not properly attached to the skin, it must be discarded regardless of the individual lifespan of the wearable unit and applicator. Therefore, to improve the ease of use and cost-effectiveness of blood glucose measurement systems using transcutaneous sensors, there is a need for an applicator that can insert the transcutaneous sensor into the correct subcutaneous position while stably attaching the wearable unit to the skin. Summary of the Invention

[0007] Technical problems to be solved

[0008] One aspect of the present invention is to provide an applicator and applicator assembly that can stably attach a wearable unit to the skin while inserting a transdermal sensor into a precise subcutaneous location.

[0009] The purpose of this invention is not limited to the above description. Other objectives of this invention will be readily apparent to those skilled in the art from the entire contents of this specification.

[0010] Solution

[0011] An applicator according to one aspect of the invention may include: a main housing having a movable space formed along a first direction; a sensor unit carrier configured to move along the movable space and including a retaining groove recessed thereon on one surface; a handle housing coupled to the main housing and configured such that at least a portion thereof contacts the sensor unit carrier to move together with the sensor unit carrier; and a fixing portion disposed on the main housing such that it moves between a fixed position in which one end is inserted into the retaining groove and a released position in which one end is disengaged from the retaining groove.

[0012] The movement of the sensor unit carrier can be restricted by the fixing part located at the fixed position, and the movement restriction of the sensor unit carrier can be released as the fixing part moves to the release position.

[0013] During the process of connecting the handle housing to the main body housing, the fixing part can move from the fixing position to the releasing position.

[0014] The fixing part may include: a bracket extending in a direction parallel to the first direction and configured to be torsional; a fixing protrusion protruding from a surface of the bracket facing the moving space toward the moving space; and a pressure-applying moving part connected to another surface of the bracket opposite to the fixing protrusion.

[0015] The handle housing may include a push arm extending from one inner end of the handle housing toward the pressure-applying moving part, and the front end of the push arm applies pressure to the pressure-applying moving part during the connection of the handle housing to the main body housing, thereby allowing the fixed part, which is located in the fixed position, to move to the released position.

[0016] The pressure-applying moving part may include a pressure-applying moving wing disposed at a position corresponding to the push arm, and the pressure-applying moving wing may be provided with a pressure-applying moving inclined surface, the pressure-applying moving inclined surface having an inclination towards the sensor unit carrier along the first direction.

[0017] The push arm may include a wing receiving hole, the wing receiving hole being formed in a shape extending through the push arm along a first direction, and after the fixing part moves to the release position, at least one end of the pressure-applying moving wing may be disposed inside the wing receiving hole.

[0018] The push arm may further include a blocking member disposed at the front end of the push arm adjacent to the fixed portion to close one end of the wing receiving hole, and one end of the pressure-applying movable wing that enters the interior of the wing receiving hole abuts against the blocking member, thereby restricting the return of the handle housing, which has moved along the first direction, to the initial position.

[0019] As the front end of the push arm applies pressure to the pressure-applying movable ramp along the first direction, the bracket can twist and deform in a direction away from the movable space at one end of the bracket connected to the fixed protrusion and the pressure-applying movable part.

[0020] The main housing may also include columnar members arranged to separate the interior of the main housing into movable spaces, and the support may be formed by cutting through one side wall of the columnar member.

[0021] The support can be configured to be separated by a first cutting groove and a second cutting groove, which are formed adjacent to each other to cut at least a portion of one side wall of the column.

[0022] An applicator assembly according to one aspect of the invention may include: a main housing having a movement space formed along a first direction, and a transmitting unit being detachably fixed to one end of the main housing; a sensor unit carrier including a fixing groove recessed on one side surface and configured to move together with a sensor unit including a transdermal sensor member in the movement space to transfer the sensor unit to the transmitting unit; a handle housing coupled to the main housing such that it is movable relative to the main housing and configured to move together with the sensor unit carrier from a first position to a second position using pressure from a user; and a fixing portion disposed on the main housing such that, during the process of coupling the handle housing to the main housing or during the process of moving the handle housing from the first position to the second position, it moves from a fixed position where one end is inserted into the fixing groove to a released position where one end is disengaged from the fixing groove.

[0023] The handle housing may include a push arm extending from one inner end of the handle housing toward the fixing part, and the fixing part may be moved from the fixing position to the releasing position by applying pressure to the fixing part through the front end of the push arm.

[0024] When the handle housing is in the first position, the front end of the push arm can be positioned at a position spaced apart from or abutting against one end of the fixing part, and the front end of the push arm can apply pressure to one end of the fixing part, so that as the handle housing moves to the second position, the fixing part moves to the release position.

[0025] The first position may be the position of the handle housing after the assembly of the applicator assembly is completed and the sensor unit carrier is in the initial position, and the second position may be the position of the handle housing after the sensor unit carrier is moved to the insertion position so that the sensor unit is transferred to the transmitting unit.

[0026] Invention Effects

[0027] According to one aspect of the invention, an applicator and applicator assembly can be provided that can stably attach a wearable unit to the skin while inserting a transdermal sensor into a precise subcutaneous location.

[0066] Preferred embodiments of the 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 invention may be modified in various ways, and the scope of the invention should not be construed as limited to the embodiments described below. These embodiments are provided to explain the invention in further detail to those skilled in the art to which this invention pertains. Therefore, for clarity, the shapes of the elements shown in the drawings may be emphasized or exaggerated.

[0067] The following will refer to Figures 1 to 26 The applicator and applicator components are described in more detail.

[0068] Applicator Components

[0069] Figure 1 This is a perspective view illustrating an exemplary embodiment of the applicator component 1, and Figure 2 This is a perspective view showing an exemplary embodiment of the applicator assembly 1 after the cover 50 has been removed. Figure 3 This is a perspective view illustrating an exemplary embodiment of the wearable unit 20, and Figure 4 This is a conceptual diagram illustrating an exemplary embodiment of a wearable unit 20 attached to body B and a remote terminal 5.

[0070] The applicator assembly 1 may include a wearable unit 20 and an applicator 10 pre-assembled with the wearable unit 20. A removable cover 50 is disposed at one end of the applicator 10. The cover 50 disposed at one end of the applicator 10 prevents the applicator 10 from being arbitrarily triggered and prevents external contaminants or moisture from entering the interior of the applicator assembly 1.

[0071] The wearable unit 20 may include a transdermal sensor component 330 inserted under the skin of the body B to detect biological information. The biological information detected by the transdermal sensor component 330 may be diverse, but the preferred biological information detected by the transdermal sensor component 330 may be glucose concentration.

[0072] The applicator 10 can be used to deliver the wearable unit 20 to a detection location on the skin, so that the end of the transdermal sensor component 330 included in the wearable unit 20 is inserted subcutaneously into the body B. One end of the wearable unit 20 may be provided with an adhesive component 430, which allows the wearable unit 20 to remain at the detection location for a certain period of time. Preferably, the wearable unit 20 may be configured on the applicator 10 such that the adhesive surface of the adhesive component 430 is exposed when the cover 50 is removed from the applicator assembly 1. The detection location is not limited to a specific location on the body B, but from a convenience perspective, the wearable unit 20 is preferably attached to the skin of body parts such as the upper arm, thigh, or abdomen.

[0073] The wearable unit 20 can be attached to the skin of body B to detect biometric information and wirelessly transmit the detected biometric data to an external terminal 5. The wireless transmission method is not particularly limited and can include Bluetooth (BT), Bluetooth Low Energy (BLE), Near Field Communication (NFC), and RFID. The external terminal 5 is also not particularly limited; it can be any device capable of receiving and processing data, such as a portable terminal, dedicated medical equipment, a PC, or a server. As a non-limiting example, the wearable unit 20 can continuously or periodically detect the glucose concentration of body B and transmit the glucose concentration data to the external terminal 5.

[0074] Wearable unit

[0075] Figure 5 This is a perspective view showing an exemplary embodiment of the sensor unit 30 in a state where the needle 1401 is connected, and Figure 6 This is a perspective view illustrating an exemplary embodiment of the connection process between the sensor unit 30 and the transmitting unit 40.

[0076] The wearable unit 20 may include a sensor unit 30 and a transmitting unit 40. The wearable unit 20 may be an integrated unit consisting of the sensor unit 30 and the transmitting unit 40 connected together, and may be disposed inside the applicator 10. In this case, during the triggering process of the applicator 10, the integrated wearable unit 20 consisting of the sensor unit 30 and the transmitting unit 40 may be attached to the skin of the body B.

[0077] Alternatively, the sensor unit 30 and the transmitting unit 40 may be arranged separately inside the applicator 10. In this case, during the insertion of the transdermal sensor member 330 subcutaneously, the sensor unit 30 and the transmitting unit 40 can be connected and arranged at the detection position. This can include all of the following situations: the sensor unit 30 and the transmitting unit 40 are connected before the transdermal sensor member 330 is inserted subcutaneously; the sensor unit 30 and the transmitting unit 40 are connected simultaneously with the insertion of the transdermal sensor member 330; and the sensor unit 30 and the transmitting unit 40 are connected after the insertion of the transdermal sensor member 330. When the wearable unit 20 is arranged inside the applicator 10 with the sensor unit 30 and the transmitting unit 40 separated, the sensor unit 30 can move relative to the transmitting unit 40 during the insertion of the transdermal sensor member 330, thereby achieving connection between the sensor unit 30 and the transmitting unit 40. That is, with the transmitting unit 40 in the detection position, the sensor unit 30 can move toward the transmitting unit 40, thereby achieving subcutaneous insertion of the transdermal sensor member 330. When the sensor unit 30 moves toward the transmitting unit 40 to achieve subcutaneous insertion of the percutaneous sensor component 330, compared to the wearable unit 20 which is set as an integral piece, even if a smaller pushing force is applied to the percutaneous sensor component 330, the percutaneous sensor component 330 can be inserted into the accurate position, and the pain and discomfort caused during the insertion of the percutaneous sensor component 330 into the subcutaneous tissue can be effectively reduced.

[0078] The transmitting unit 40 may include a transmitting unit housing 410 that constitutes the exterior of the transmitting unit 40. A first transmitting unit housing 410a and a second transmitting unit housing 410b may be connected to each other to form the transmitting unit housing 410, and the interior of the transmitting unit housing 410 may house a battery for power supply and electronic units for transmitting bio-information data. The connection portion between the first transmitting unit housing 410a and the second transmitting unit housing 410b may be provided with a sealing portion to prevent external contaminants or moisture from entering the interior of the transmitting unit housing 410.

[0079] At one end of the first transmitting unit housing 410a, a mounting groove 412 for accommodating and connecting the sensor unit 30 may be formed. This mounting groove 412 is recessed towards the inside of the transmitting unit housing 410. The mounting groove 412 may be shaped to recess from one surface of the first transmitting unit housing 410a towards the inside of the transmitting unit housing 410. Preferably, the mounting groove 412 may be shaped to correspond to the shape of the sensor unit housing 310, which will be described later. In the region of the first transmitting unit housing 410a on the side where the mounting groove 412 is formed, a side protrusion 414 protruding towards the mounting groove 412 may be provided. The side protrusion 414 may be divided into multiple parts by a dividing portion 415, and the sensor unit housing protrusion 311, described later, may be arranged in the dividing portion 415.

[0080] A first access opening 416, connecting the interior and exterior of the transmitting unit housing 410, is formed through a surface of the first transmitting unit housing 410a that has a mounting groove 412. A transmitting unit access portion 420, connected to an electronic unit disposed inside the transmitting unit housing 410, is exposed through the first access opening 416. The shape of the transmitting unit access portion 420 is not limited to the shape shown in the figures; it can be applied in various variations without limitation, as long as its shape allows for electrical connection to the access terminal intended for connection to the transmitting unit access portion 420. The transmitting unit access portion 420 is preferably made of a conductive material; more preferably, from the perspective of contact safety, it can be made of a material or structure that is itself elastic.

[0081] At one end of the boundary between the first transmitting unit housing 410a and the first access opening 416, a fastening latch 413 may be provided, protruding in a direction toward the inside of the mounting groove 412. The fastening latch 413 may be connected to a fastening ring 315, which will be described later. By fastening the fastening latch 413 to the fastening ring 315, a secure connection between the sensor unit 30 and the transmitting unit 40 can be maintained.

[0082] An insertion hole 411 is formed inside the mounting groove 412. This insertion hole 411 is shaped to penetrate the first transmitting unit housing 410a and the second transmitting unit housing 410b. When the percutaneous sensor component 330 is inserted subcutaneously, the needle body 1402 and the percutaneous sensor component 330 can pass through the insertion hole 411 and be inserted subcutaneously. After the end of the percutaneous sensor component 330 is inserted subcutaneously, the needle body 1402 is withdrawn from the skin through the insertion hole 411, while one end of the percutaneous sensor component 330 remains inserted subcutaneously.

[0083] An adhesive member 430 may be disposed at the end of the second transmitting unit housing 410b opposite to the end where the mounting groove 412 is formed. By attaching the adhesive member 430 to the skin, the wearable unit 20 can remain in the detection position for a certain period of time. The adhesive member 430 may have a first adhesive surface attached to the skin and a second adhesive surface attached to one end of the second transmitting unit housing 410b. An additional protective film may be provided on the first adhesive surface attached to the skin to protect the first adhesive surface before attachment to the skin. Figure 6 In this embodiment, the area of ​​the adhesive member 430 is set to be larger than one end of the second transmitting unit housing 410b, but the shape of the adhesive member 430 is not necessarily limited to this. The adhesive member 430 may be configured to have an area corresponding to one end of the second transmitting unit housing 410b, or it may be configured to have an area smaller than one end of the second transmitting unit housing 410b. The adhesive member 430 may be provided separately so that the user attaches it to the transmitting unit housing 410 during the insertion of the transdermal sensor member 330 subcutaneously, but it may also include a state in which the adhesive member 430 is pre-attached to the transmitting unit housing 410 disposed inside the applicator assembly 1.

[0084] On the side end of the second transmitting unit housing 410b facing the adhesive member 430, a transmitting unit housing groove 417 may be provided, recessed towards the inner side of the transmitting unit housing 410. The end of the abutment 1164 provided on the transmitting unit support 1160, described later, may be arranged inside the transmitting unit housing groove 417, in which case the transmitting unit 40 can be effectively prevented from arbitrarily detaching from the applicator 10.

[0085] The sensor unit 30 may include: a sensor unit housing 310, which constitutes the exterior of the sensor unit 30; and a transdermal sensor member 330, which is disposed inside the sensor unit housing 310 and configured such that one end is exposed outside the sensor unit housing 310. When the wearable unit 20 is attached to the body B, the end of the transdermal sensor member 330 exposed outside the sensor unit housing 310 can remain inserted subcutaneously, and biometric information can be detected by the transdermal sensor member 330 inserted subcutaneously.

[0086] The sensor unit housing 310 can be formed by connecting a first sensor unit housing 310a and a second sensor unit housing 310b to each other. A sealing portion can be provided at the connection between the first sensor unit housing 310a and the second sensor unit housing 310b to prevent external contaminants or moisture from entering the interior of the sensor unit housing 310. On the side end of the second sensor unit housing 310b, a plurality of recesses 312 are formed at certain intervals along the circumference of the second sensor unit housing 310b. The recesses 312 have a shape that is recessed from the side of the second sensor unit housing 310b. On a surface of the first sensor unit housing 310a facing the second sensor unit housing 310b, sensor unit housing protrusions 311 can be provided, which protrude at positions corresponding to the plurality of recesses 312. The sensor unit housing protrusion 311 and recess 312 can be configured such that, when the first sensor unit housing 310a and the second sensor unit housing 310b are connected, the sensor unit housing protrusion 311 is in close contact with the recess 312, or the sensor unit housing protrusion 311 has a shape that can apply pressure to the recess 312. Since the sensor unit housing protrusion 311 remains in close contact with or applies pressure to the recess 312 when the first sensor unit housing 310a and the second sensor unit housing 310b are connected, the first sensor unit housing 310a and the second sensor unit housing 310b can maintain a more secure connection. Furthermore, the side protrusion 414 formed on the transmitting unit housing 410 can be configured to have a shape such that, when the sensor unit 30 and the transmitting unit 40 are connected, the side protrusion 414 can make close contact with or apply pressure to the side end of the second sensor unit housing 310b. Through this close contact or pressure, the sensor unit 30 and the transmitting unit 40 can maintain a more secure fixed state. When the sensor unit 30 and the transmitting unit 40 are connected, the sensor unit housing protrusion 311 can be arranged inside the partition 415 formed at the side end of the mounting groove 412. The sensor unit housing protrusion 311 can make close contact with a surface of the first transmitting unit housing 410a forming the partition 415, or a surface of the first transmitting unit housing 410a forming the partition 415 can apply pressure to the sensor unit housing protrusion 311.

[0087] A second access opening 316, connecting the interior and exterior of the sensor unit housing 310, is formed through one end of the second sensor unit housing 310b, which faces the mounting groove 412 when the sensor unit 30 and the transmitting unit 40 are connected. The sensor unit access portion 320, connected to the transdermal sensor component 330, is exposed through the second access opening 316. When the sensor unit 30 and the transmitting unit 40 are connected, the sensor unit access portion 320 and the transmitting unit access portion 420 are in electrical contact with each other, and the bio-information data detected by the transdermal sensor component 330 can be transmitted to the electronic unit disposed in the transmitting unit 40 through the sensor unit access portion 320 and the transmitting unit access portion 420.

[0088] A boss 313 may be provided at the end of the second sensor unit housing 310b facing the transmitting unit 40. The boss 313 is formed in a shape corresponding to the insertion hole 411. A through hole 314 connecting the interior and exterior of the sensor unit housing 310 may be formed through the boss 313. One end of the transdermal sensor member 330, which is intended to be inserted subcutaneously, may be arranged to extend from the interior of the sensor unit housing 310 through the through hole 314 to the exterior of the sensor unit housing 310. The through hole 314 may extend through both the second sensor unit housing 310b and the first sensor unit housing 310a. The needle body 1402 may be arranged to extend through the through hole 314 when the sensor unit 30 and the needle 1401 are connected. At this time, one end of the transdermal sensor member 330 extending to the exterior of the sensor unit housing 310 may be arranged outside the sensor unit housing 310 in a state where it is accommodated inside the needle body 1402. When the sensor unit 30 and the transmitting unit 40 are connected, the circumferential side of the boss 313 and the inner side of the insertion hole 411 of the transmitting unit housing 410 can abut against each other in a tight contact. This allows not only the percutaneous sensor member 330 to be inserted into the accurate position, but also ensures a more secure connection between the sensor unit 30 and the transmitting unit 40. Furthermore, with the sensor unit 30 and the transmitting unit 40 connected, the tight contact between the circumferential side of the boss 313 and the inner side of the insertion hole 411 of the transmitting unit housing 410 effectively prevents external contaminants or moisture from entering the sensor unit access portion 320 and the transmitting unit access portion 420 when the wearable unit 20 is attached to the body B.

[0089] At one end of the boundary between the second sensor unit housing 310b and the second access opening 316, a fastening ring 315 may be provided, protruding in a direction parallel to the protruding direction of the transcutaneous sensor member 330. During the connection process between the sensor unit 30 and the transmitting unit 40, the fastening locking member 413 is fixed to the fastening ring 315, and through the mutual connection of the fastening locking member 413 and the fastening ring 315, the sensor unit 30 and the transmitting unit 40 can maintain a secure connection. In the above description, an example was given where the first transmitting unit housing 410a has a fastening locking member 413 and the second sensor unit housing 310b has a fastening ring 315. However, the present invention also includes cases where the second sensor unit housing 310b has a fastening locking member 413 and the first transmitting unit housing 410a has a fastening ring 315. Furthermore, the fastening devices for the sensor unit 30 and the transmitting unit 40 are not limited to locking elements and rings. They can be used in various variations as long as they can prevent the sensor unit 30 from moving to the transmitting unit 40 during the insertion of the percutaneous sensor member 330 under the skin, and prevent the sensor unit 30 from separating from the transmitting unit 40 after the sensor unit 30 and the transmitting unit 40 are connected.

[0090] A retaining groove 317 is recessed into one surface of the first sensor unit housing 310a, and the front end of a retaining protrusion 1317 formed on the sensor unit carrier 130 (described later) can be inserted into and disposed in the retaining groove 317. During the insertion of the percutaneous sensor component 330 subcutaneously, the sensor unit 30 moves toward the transmitting unit 40 together with the sensor unit carrier 130, and as the sensor unit 30 moves, the front end of the retaining protrusion 1317 remains inserted into the retaining groove 317, allowing the sensor unit 30 to move while being stably supported by the sensor unit carrier 130. After the percutaneous sensor component 330 is inserted subcutaneously, during the process of the user removing the applicator 10 from the skin, the retaining protrusion 1317 exits from the retaining groove 317, thereby releasing the fixed relationship between the sensor unit carrier 130 and the sensor unit 30.

[0091] Applicator

[0092] Figure 7 and Figure 8 This is an exploded perspective view showing an exemplary embodiment of the applicator assembly 1 with the cover 50 removed. Hereinafter, for ease of explanation, the direction substantially parallel to the insertion direction of the transdermal sensor member 330 is defined as the first direction, and all directions substantially perpendicular to the first direction are defined as the second direction, thereby describing the specific structure of the applicator 10 and the applicator assembly 1.

[0093] The applicator 10 can be configured to deliver the wearable unit 20 to a detection location on the skin. The applicator 10 may include: a main housing 110, one end of which is detachably connected to the transmitting unit 40; a handle housing 120, arranged to move relative to the main housing 110 in a first direction when the percutaneous sensor member 330 is inserted subcutaneously; a sensor unit carrier 130, one end of which is detachably connected to the sensor unit 30 and arranged to move together with the handle housing 120 in the first direction; a needle carrier 140 having a needle body 1402 for inserting the percutaneous sensor member 330 subcutaneously and detachably fixed to the sensor unit carrier 130; and an elastic member 150, one end of which is connected to the sensor unit carrier 130 and the needle carrier 140 respectively to provide a driving force so that the needle body 1402 inserted subcutaneously is withdrawn from the body B.

[0094] 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 main body housing 110; a sensor unit 30 detachably disposed to one end of the sensor unit carrier 130; and a cover 50 detachably connected to the handle housing 120 to prevent the main body housing 110, on which the transmitting unit 40 is disposed, from being exposed.

[0095] Handle housing

[0096] Figure 9 and Figure 10 These are perspective and bottom views illustrating an exemplary embodiment of the handle housing 120, and Figure 11 It is along Figure 9 and Figure 10 The cross-sectional view of the handle housing 120 is taken from line A-A'.

[0097] The handle housing 120, together with the main housing 110, forms the appearance of the applicator 10. During the insertion of the transdermal sensor component 330 subcutaneously, the user can hold or press the handle housing 120. Although Figures 9 to 11 The handle housing 120 shown is cup-shaped, but the shape of the handle housing 120 is not necessarily limited to cup-shaped. Various variations can be adopted as long as the shape can achieve the following functions. However, since the cover 50 can be detachably connected to one end of the handle housing 120 by a threaded connection, it is more preferable to set the end of the handle housing 120 with threads for threaded connection as a cylindrical structure.

[0098] A first internal space 1202 is formed inside the handle housing 120, which communicates with the outside through a first opening 1201 formed at one end of the handle housing 120. A push arm 1230 may be formed extending from an inner surface of the handle housing 120 facing the first opening 1201 along a first direction. The push arm 1230 may be configured to interact with a fixing portion 1130, described later, and during the assembly of the applicator 10, pressing and moving the fixing portion 1130 by the push arm 1230 can release the temporary movement restriction of the fixing portion 1130 on the sensor unit carrier 130. A push arm slit 1232 may be formed in a shape that divides the end of the push arm 1230, extending from the front end of the push arm 1230 in a direction opposite to the protruding direction of the push arm 1230. The pressure-moving extension 1136, located in the fixing part 1130 (described later), can be arranged within the push arm slit 1232 to eliminate interference from the movement of the pressure-moving extension 1136 relative to the push arm 1230 during the assembly of the applicator 10 or the subcutaneous insertion of the percutaneous sensor component 330. Figures 9 to 11 The push arm 1230 is shown as being symmetrically formed based on the push arm slit 1232, but the shape of the push arm 1230 is not necessarily limited to this. As long as it is a structure that can press and move the fixing part 1130 during the assembly of the applicator 10, it can be applied in various variations.

[0099] On one side of the push arm slit 1232, a wing-receiving hole 1231 extending along a first direction can be formed, which penetrates the push arm 1230 along the thickness direction. Alternatively, the wing-receiving hole 1231 may not completely penetrate the push arm 1230 along the thickness direction, but may be formed as a recess on one side surface of the push arm 1230 that abuts against the pressure-applying movable wing 1133 as the handle housing 120 moves along the first direction. The shape and position of the wing-receiving hole 1231 can be configured to correspond to the pressure-applying movable wing 1133, and when the pressure-applying movable wing 1133 is arranged in pairs, the wing-receiving hole 1231 can be formed symmetrically with respect to the push arm slit 1232.

[0100] Preferably, the wing receiving hole 1231 can be configured not to extend to the end of the push arm 1230 that initially abuts against the pressure-applying movable wing 1133 as the handle housing 120 moves along the first direction. That is, the wing receiving hole 1231 can be formed in the push arm 1230 in a shape extending along the first direction, but due to the stopper 1231' located at the end of the push arm 1230, the wing receiving hole 1231 can have a shape that does not extend to the end of the push arm 1230. The stopper 1231' can be configured to close the wing receiving hole 1231 in the end region of the push arm 1230. During the movement of the handle housing 120 along the first direction, at least one end of the pressure-applying movable wing 1133 can enter the interior of the wing receiving hole 1231, and the end of the pressure-applying movable wing 1133 entering the wing receiving hole 1231 abuts against the stopper 1231', thereby restricting the movement of the push arm 1230 in a direction opposite to the first direction. In other words, through the interaction between the push arm 1230 and the fixing part 1130, the handle housing 120 can be restricted to return to the initial position after the percutaneous sensor component 330 is inserted subcutaneously.

[0101] A carrier fixing baffle 1207 can be provided on the inner surface of the handle housing 120 facing the first opening 1201, positioned adjacent to the push arm 1230. The carrier fixing baffle 1207 can be arranged upright with a shape that corresponds entirely or partially to the circumference of one end of the sensor unit carrier 130. During the assembly of the applicator 10, one end of the sensor unit carrier 130 can be inserted into the carrier fixing baffle 1207, thereby connecting the sensor unit carrier 130 and the handle housing 120. The circumferential surface of one end of the sensor unit carrier 130 is in close contact with and fixed to the inner surface of the carrier fixing baffle 1207, so when the percutaneous sensor component 330 is inserted subcutaneously, the sensor unit carrier 130 can move together with the handle housing 120 in the first direction.

[0102] On the inner surface of the handle housing 120 forming the first internal space 1202, a guide protrusion 1210 extending in a first direction in a shape protruding toward the first internal space 1202 may be provided. The front end of the guide protrusion 1210 is disposed inside the handle housing guide groove 1142 recessed on the outer surface of the main housing 110, which will be described later, and the interaction between the guide protrusion 1210 and the handle housing guide groove 1142 can guide the movement direction of the handle housing 120 moving in the first direction. The guide protrusions 1210 may be provided in pairs in a symmetrical shape on the inner surface of the handle housing 120, and the handle housing guide groove 1142 may also be recessed at a position corresponding to the guide protrusion 1210 in a shape corresponding to the guide protrusion 1210. In addition, although the case in which the guide protrusion 1210 is formed on the handle housing 120 and the handle housing guide groove 1142 is formed on the main housing 110 has been described as an example, the case in which the guide groove is formed on the handle housing and the guide protrusion is formed on the main housing may also be included.

[0103] The first movement restriction portion 1220 may be formed to protrude from the inner 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 restriction portion 1220 may interact with a second movement restriction portion 1150 provided in the main housing 110, which will be described later. Through the interaction between the first movement restriction portion 1220 and the second movement restriction portion 1150, the handle housing 120 attached to the main housing 110 may be restricted from arbitrarily detaching from the main housing 110, or the handle housing 120 may be restricted from moving in a direction opposite to the first direction after the percutaneous sensor member 330 is inserted subcutaneously. The first movement restriction part 1220 can be configured as a locking structure having a wedge-shaped cross-section including an inclined surface 1221 and a support surface 1222. However, the shape of the first movement restriction part 1220 is not necessarily limited to this, and any shape can be applied without restriction, as long as the shape can restrict the handle housing 120 from arbitrarily disengaging from the main housing 110 by interaction with the second movement restriction part 1150, or restrict the handle housing 120 from moving in the opposite direction to the first direction after the percutaneous sensor member 330 is inserted subcutaneously.

[0104] The outer surface of one end of the handle housing 120, where the first opening 1201 is formed, may be provided with a threaded portion 1240 for threaded connection with the cover 50. The threaded portion 1240 formed on the handle housing 120 and the threaded portion 540 formed on the cover 50 (described later) can be threadedly connected, so that the handle housing 120 and the cover 50 can be detachably connected to each other. A locking protrusion 1242 may be provided on the outer surface of the handle housing 120, which has the following shape: protruding outward from the outer surface of the handle housing 120 and extending circumferentially along the handle housing 120. Since the locking protrusion 1242 is configured to abut against the front end of the cover 50, over-tightening of the threaded portion 1240 of the handle housing 120 and the threaded portion 540 of the cover 50 can be prevented when the handle housing 120 and the cover 50 are screwed together. Furthermore, the handle housing 120 and the cover 50 can be configured such that the locking protrusion 1242 and the end of the cover 50 can be in close contact when they are connected. In this case, external contaminants or moisture can be effectively prevented from entering the interior of the applicator assembly 1. Although a threaded connection using threads formed on the handle housing 120 and the cover 50 respectively has been described as an example of the connection method of the handle housing 120 and the cover 50, various connection methods can be applied to the handle housing 120 and the cover 50 in variations, such as mating connection and fastening using a latch.

[0105] Although the example of a connection between the handle housing 120 and the cover 50 using threaded connections formed on the handle housing 120 and the cover 50 respectively has been described, various connection methods can be applied to the handle housing 120 and the cover 50 in variations, such as mating connections and latching connections. Furthermore, the fastening members used to connect the handle housing 120 and the cover 50 can be provided not only in an odd number on both the handle housing 120 and the cover 50, but also in cases where multiple fastening members are arranged at corresponding positions on the handle housing 120 and the cover 50.

[0106] Main body shell

[0107] Figure 12 These are perspective views and partial enlarged views illustrating an exemplary embodiment of the main housing 110. Figure 13 This is a bottom view showing an exemplary embodiment of the main housing 110, and Figure 14 This is a plan view showing an exemplary embodiment of the main housing 110. Figure 15 It is along Figure 14 The cross-sectional view of the main body shell 110 taken by line B-B', and Figure 16 It is along Figure 14 A three-dimensional view of a partial cross-section of the main shell 110 taken by line C-C'. Figure 17(a) to (c) are perspective views illustrating exemplary variations of the fixing part. Figure 18 (a) is a perspective view showing an exemplary variant example of the fixing part, and Figure 18 (b) is along Figure 18 (a) is a partial cross-sectional view of D-D'.

[0108] The main housing 110 is configured to support the sensor unit carrier 130 arranged inside the applicator 10, so as to guide the movement direction of the sensor unit carrier 130 and limit the movement range of the sensor unit carrier 130, and the transmitting unit 40 for attachment to the body B is detachably fixedly arranged at one end of the main housing 110.

[0109] The main housing 110 may include a main housing body portion 1100, which has a circumferential surface with a shape corresponding to the first internal space 1202 of the handle housing 120. The main housing body portion 1100 has a second internal space 1102 inside, which communicates with the outside through a second opening 1101 formed at one end of the main housing 110 adjacent to the handle housing 120. When the main housing 110 and the handle housing 120 are assembled together, the second internal space 1102 formed in the main housing 110 and the first internal space 1202 formed in the handle housing 120 can communicate with each other, thereby forming an internal space (not shown) inside the applicator 10 that is distinct from the outside. Furthermore, the other end of the main housing 110, facing the end with the second opening 1101, can be closed.

[0110] Inside the main housing 110, a columnar member 1110 through which the first moving space 1111 extends in a first direction can be arranged upright. The columnar member 1110 may include a plurality of spacer walls 1112, which extend from the inner surface of the closed other end of the main housing 110 in a direction opposite to the first direction and are arranged upright. The plurality of spacer walls 1112 are configured to surround the first moving space 1111 from the side and can be used to distinguish the second internal space 1102 from the first moving space 1111. During the insertion of the percutaneous sensor component 330 into the subcutaneous tissue, the sensor unit carrier body 1310, the needle carrier 140, and the sensor unit 30 of the sensor unit carrier 130, described later, can move toward the transmitting unit 40 through the first moving space 1111.

[0111] A first acceleration locking member 1118 may be provided on the outer surface of any one or more of the plurality of spacers 1112. The first acceleration locking member 1118 has a shape that protrudes outward from the outer surface of the spacer 1112. The first acceleration locking member 1118 may interact with a second acceleration locking member 1328 provided on the sensor unit carrier 130, which will be described later, to provide a movement initiation condition for the sensor unit carrier 130, such that the sensor unit carrier 130 moves in the first direction only when a force greater than a certain amount is applied to the sensor unit carrier 130. That is, since the percutaneous insertion of the transdermal sensor member 330 will only occur when the force applied to the handle housing 120 is sufficient to release the movement restriction of the second acceleration locking member 1328 by the first acceleration locking member 1118, the situation where the user arbitrarily triggers the transdermal sensor member 330 under unexpected circumstances can be effectively prevented. Furthermore, in order for the percutaneous sensor component 330 to be properly inserted subcutaneously, the needle body 1402 needs to move at a speed higher than the reference speed so that the tip of the needle body 1402 pierces the skin surface. By providing acceleration conditions, the needle body 1402 is triggered at a speed higher than the reference speed through the interaction of the first acceleration locking member 1118 and the second acceleration locking member 1328, which can effectively guide the percutaneous sensor component 330 to be properly inserted subcutaneously. The first acceleration locking member 1118 can be configured as a locking member structure with a wedge-shaped cross-section including a slope 1119a and a support surface 1119b, but the shape of the first acceleration locking member 1118 is not necessarily limited to this. As long as the shape can provide the movement start conditions or acceleration conditions of the sensor unit carrier 130 through the interaction with the second acceleration locking member 1328, it can be applied in various variations.

[0112] At the front end of the partition wall 1112, which is provided with the first acceleration locking member 1118, a bridging member pressure portion 1116 with a cross-section decreasing towards the front end may be provided. The bridging member pressure portion 1116 may be configured to apply pressure to the bridging member 1330 provided in the sensor unit carrier 130, which will be described later, thereby causing the bridging member 1330 to break. That is, in the initial stage of the movement of the sensor unit carrier 130 along the first direction, the bridging member 1330 provided on the sensor unit carrier 130 moves to a position in close contact with the bridging member pressure portion 1116, and the movement of the sensor unit carrier 130 along the first direction can only end when a first directional force sufficient to cause the bridging member 1330 to break under the pressure of the bridging member pressure portion 1116 is applied to the sensor unit carrier 130. If the bridging member 1330 does not break despite the sensor unit carrier 130 moving along the first direction, the bridging member 1330 will remain pressed against the bridging member pressure part 1116, preventing the sensor unit carrier 130 from moving further along the first direction. In other words, through the interaction between the bridging member 1330 and the bridging member pressure part 1116, not only can the user be effectively prevented from arbitrarily triggering the transdermal sensor component 330 under unexpected circumstances, but sufficient acceleration conditions can also be provided to allow the transdermal sensor component 330 to be properly inserted subcutaneously.

[0113] Between the first acceleration locking member 1118 and the bridging member pressure application portion 1116, a carrier slit 1117 may be provided. This carrier slit 1117 is formed through the spacer wall 1112 in a shape that cuts through the spacer wall 1112 from its front end along a direction parallel to the opposite direction to the first direction. During the movement of the sensor unit carrier 130 along the first direction, the extension arm connection portion 1322 of the sensor unit carrier 130, described later, can enter the interior of the carrier slit 1117. As the extension arm connection portion 1322 enters the interior of the carrier slit 1117, the obstruction of the spacer wall 1112 to the movement of the extension arm connection portion 1322 along the first direction can be eliminated, and the movement of the sensor unit carrier 130 can be guided through the carrier slit 1117. As the extension 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 transferred to the mounting slot 412 of the transmitting unit 40.

[0114] On the inner surface of the partition wall 1112 forming the first moving space 1111, a carrier guide groove 1114 recessed along a direction intersecting the first direction can be formed, and the carrier guide groove 1114 can be formed to extend along the first direction. For example, the carrier guide groove 1114 can be recessed in a shape that extends outward from the inner surface of the partition wall 1112. The sensor unit carrier 130 can be provided with a carrier guide protrusion 1310a in a shape corresponding to the carrier guide groove 1114. The carrier guide protrusion 1310a can be formed to protrude from one end of the sensor unit carrier body 1310 toward a direction intersecting the first direction and extend along the first direction. At least one end of the carrier guide protrusion 1310a can be disposed inside the carrier guide groove 1114. The front end of the carrier guide protrusion 1310a can be disposed in the carrier guide groove 1114 to guide the movement of the sensor unit carrier 130, causing the sensor unit carrier 130 to move along the first direction. The figure exemplarily shows four carrier guide protrusions 1310a arranged at each corner of the sensor unit carrier 130, and carrier guide grooves 1114 formed at corresponding positions and in corresponding numbers on the inner surface of the column 1110. However, the shape and number of the carrier guide protrusions 1310a and the carrier guide grooves 1114 are not necessarily limited to the shape and number shown in the figure. As long as the shape and number are capable of guiding the sensor unit carrier 130 to move in the first direction, they can be applied in various variations.

[0115] The partition wall support 1113, which serves as a support for the column 1110, can be erected inside the second internal space 1102. The partition wall support 1113 is arranged such that one end is connected to the partition wall 1112 and the other end is connected to the inner wall of the main body shell 1100, thereby improving the structural safety and rigidity of the column 1110 and the main body shell 1100.

[0116] The body extension 1140 can be provided in pairs at one end of the main body housing 1100, and its shape extends from one end of the main body housing 1100 where the second opening 1101 is formed along a direction opposite to the first direction. The handle housing guide groove 1142 can be formed to extend along the first direction from the outer surface of the front end of the body extension 1140 to the outer surface of the other end of the main body housing 1100. That is, the handle housing guide groove 1142 can be formed by extending from the outer surface of the body extension 1140 to the outer surface of the main body housing 1100 and being recessed, with a shape that spans the body extension 1140 and the main body housing 1100. The front end of the guide protrusion 1210 of the handle housing 120 is arranged inside the handle housing guide groove 1142, thereby guiding the movement direction of the handle housing 120 moving along the first direction.

[0117] A second movement limiting portion 1150 may be provided at the front end of the main body extension 1140. A movement limiting locking member receiving portion 1156 may be formed through the front end of the main body extension 1140, and the movement limiting locking member receiving portion 1156 has a shape that cuts the main body extension 1140 along a first direction from the front end of the main body extension 1140. The movement limiting body 1151 is arranged to be received in the movement limiting locking member receiving portion 1156, and the two side ends of the central portion of the movement limiting body 1151 can be connected to the main body extension 1140 through the body connecting portion 1157. Since the two side ends of the central portion of the movement limiting body 1151 are connected to the main body extension 1140 through the body connecting portion 1157, when the movement limiting body 1151 is subjected to an external force, the movement limiting body 1151 can undergo torsional deformation while being received in the movement limiting locking member receiving portion 1156. A first movement limiting locking member 1152 may be provided on the outer surface of one end of the movement limiting body 1151, and a second movement limiting locking member 1154 may be provided on the outer surface of the other end of the movement limiting body 1151. Preferably, the first movement limiting locking member 1152 and the second movement limiting locking member 1154 may be arranged to be spaced apart from each other along a first direction. The first movement limiting locking member 1152 may be configured as a locking member structure having a wedge-shaped cross-section including a first inclined surface 1153a and a first support surface 1153b, and the second movement limiting locking member 1154 may also be configured as a locking member structure having a wedge-shaped cross-section including a second inclined surface 1155a and a second support surface 1155b. The first movement limiting locking member 1152 and the second movement limiting locking member 1154 may interact with the first movement limiting portion 1220 of the aforementioned handle housing 120, thereby limiting the movement of the handle housing 120.

[0118] The support surface 1222 of the first movement limiting part 1220 can be formed in a direction substantially parallel to the second direction, and the inclined surface 1221 of the first movement limiting part 1220 can be arranged at an angle, such that the protruding end of the support surface 1222 approaches the inner wall of the handle housing 120 in the first direction. The first support surface 1153b of the first movement limiting locking member 1152 can be formed in a direction substantially parallel to the second direction, and the first inclined surface 1153a of the first movement limiting locking member 1152 can be arranged at an angle, such that the protruding end of the first support surface 1153b approaches one end of the movement limiting body 1151 in a direction opposite to the first direction. The second support surface 1155b of the second movement limiting locking member 1154 can be formed in a direction substantially parallel to the second direction, and the second inclined surface 1155a of the second movement limiting locking member 1154 can be arranged at an angle, such that the protruding end of the second support surface 1155b approaches the other end of the movement limiting body 1151 in a direction opposite to the first direction.

[0119] During the assembly of the handle housing 120 and the main housing 110, as the handle housing 120 moves relative to the main housing 110 along the first direction, the inclined surface 1221 of the first movement limiting part 1220 abuts against the first inclined surface 1153a of the first movement limiting locking member 1152. Then, as the handle housing 120 moves further along the first direction, one end of the movement limiting body 1151 twists and deforms toward the second internal space 1102, thereby allowing the first movement limiting part 1220 to pass through the first movement limiting locking member 1152. After the first movement limiting part 1220 passes through the first movement limiting locking member 1152, the movement limiting body 1151 can return to its state before twisting and deformation. After the first movement limiting part 1220 passes through the first movement limiting locking member 1152 and the handle housing 120 is connected to the main body housing 110, the support surface 1222 of the first movement limiting part 1220 and the first support surface 1153b of the first movement limiting locking member 1152 are facing each other. In this way, even if a force opposite to the first direction is applied to the handle housing 120, the support surface 1222 of the first movement limiting part 1220 and the first support surface 1153b of the first movement limiting locking member 1152 can support each other, thereby preventing the handle housing 120 from arbitrarily detaching from the main body housing 110.

[0120] During the subcutaneous insertion of the percutaneous sensor component 330, the handle housing 120 moves along the first direction with the inclined surface 1221 of the first movement limiting part 1220 abutting against the second inclined surface 1155a of the second movement limiting lock 1154. The other end of the movement limiting body 1151 twists and deforms towards the second internal space 1102, causing the first movement limiting part 1220 to pass through the second movement limiting lock 1154. After the first movement limiting part 1220 passes through the second movement limiting lock 1154, the movement limiting body 1151 can return to its state before the twisting deformation. When the first movement limiting part 1220 passes through the second movement limiting lock 1154 and the subcutaneous insertion of the percutaneous sensor component 330 is completed, the support surface 1222 of the first movement limiting part 1220 and the second support surface 1155b of the second movement limiting lock 1154 are facing each other, thereby restricting the handle housing 120 from moving in the opposite direction to the first direction. In other words, after the percutaneous sensor component 330 is inserted subcutaneously, the interaction between the first movement restriction part 1220 and the second movement restriction part 1150 can prevent the handle housing 120 from returning to the position before the percutaneous sensor component 330 was inserted, thereby effectively preventing the applicator 10 from being used again after being triggered.

[0121] A fixing part 1130 may be provided on any one of the multiple partition walls 1112 to restrict the arbitrary movement of the sensor unit carrier 130 when assembling the applicator 10.

[0122] At the front end of the partition wall 1112, which is provided with a fixing part 1130, a first groove 1135a and a second groove 1135b, which are spaced apart from each other and parallel, can be formed through it. The first groove 1135a and the second groove 1135b are formed to cut the partition wall 1112 from the front end of the partition wall 1112 along a first direction. The bracket 1134 is arranged upright between the first groove 1135a and the second groove 1135b in a direction parallel to the first direction, and a fixing protrusion 1137 protruding toward the first moving space 1111 can be provided on a surface of the bracket 1134 facing the first moving space 1111.

[0123] On the other surface of the support 1134, opposite to the surface where the fixing protrusion 1137 is formed, a pressure-applying moving extension 1136 extending from the other surface of the support 1134 may be provided, and a pressure-applying moving part 1131 may be provided at the protruding front end of the pressure-applying moving extension 1136. The front end of the fixing protrusion 1137 may be arranged inside the first moving space 1111, and the fixing protrusion 1137 and the pressure-applying moving extension 1136 may be arranged parallel to each other in a direction generally parallel to the second direction. The support 1134 may be arranged on the boundary between the first moving space 1111 and the second internal space 1102, and the pressure-applying moving extension 1136 and the pressure-applying moving part 1131 may be arranged in the region corresponding to the second internal space 1102. The pressure-applying moving part 1131 may include a pressure-applying moving main body 1132 connected to the pressure-applying moving extension 1136 and pressure-applying moving wings 1133 provided at two side ends of the pressure-applying moving main body 1132. The pressure-applying movable wing 1133 may be arranged spaced apart from the pressure-applying movable extension 1136. The pressure-applying movable wing 1133 may have a pressure-applying movable ramp 1133', which has a shape that approaches the partition wall 1112 along a first direction. The fixing part 1130 may be positioned relative to... Figure 14 The C-C' symmetrical shape setting.

[0124] In addition, such as Figure 17 As shown in (a), the pressure-applying moving part 1131a may include a pressure-applying moving wing 1133a. That is, the pressure-applying moving extension 1136a may be configured to extend from the support 1134a to the region corresponding to the second internal space 1102, and the pressure-applying moving main body 1132a may be configured to extend from the front end of the pressure-applying moving extension 1136a toward one side. In other words, one end of the pressure-applying moving extension 1136a may be connected to the pressure-applying moving main body 1132a and may be arranged substantially parallel to the adjacent partition wall 1112. The pressure-applying moving wing 1133a may be arranged at the other end of the pressure-applying moving main body 1132a, and the fixing part 1130a may be configured in an asymmetrical shape.

[0125] like Figure 17 As shown in (b), the pressure-applying inclined surface 1133b disposed on the pressure-applying moving wing 1133b may include a first inclined surface 1133b' and a second inclined surface 1133b'' with different inclination angles. The second inclined surface 1133b'' may be arranged relatively closer to the partition wall 1112 than the first inclined surface 1133b', and the second inclined surface 1133b'' may be configured to have a relatively gentler inclination angle relative to the second direction than the first inclined surface 1133b'. As the handle housing 120 moves along the first direction, the push arm 1230 moves such that its front end contacts the first inclined surface 1133b'' and the second inclined surface 1133b'' in sequence, and the second inclined surface 1133b'' has a relatively gentler inclination angle relative to the second direction than the first inclined surface 1133b', thereby providing a boundary point for the movement of the handle housing 120 along the first direction. In other words, since the second inclined surface 1133b'' has a gentler angle of inclination relative to the second direction than the first inclined surface 1133b'', the front end of the push arm 1230 can only pass through the second inclined surface 1133b'' when the handle housing 120 is pressed with gradually increasing pressure in the first direction or when it is continuously pressed in the first direction. This effectively prevents arbitrary triggering of the percutaneous sensor component 330 by the user without their consent. In addition, depending on the usage environment, there may be situations where the initial acceleration conditions of the applicator assembly 1 are important. In such cases, the pressure-moving inclined surface 1133b can be configured such that the first inclined surface 1133b' has a gentler angle of inclination relative to the second direction than the second inclined surface 1133b''. In other words, since the first inclined plane 1133b' has a gentler angle of inclination relative to the second direction than the second inclined plane 1133b'', the percutaneous sensor member 330 can only be triggered when an initial pressure in the first direction, sufficient to allow the front end of the push arm 1230 to pass through the first inclined plane 1133b', is applied to the handle housing 120, and the percutaneous sensor member 330 can be inserted into the subcutaneous position under the condition of being provided with initial acceleration.

[0126] like Figure 17As shown in (c), a fixing auxiliary groove 1133c' recessed in a direction opposite to the first direction may be provided at one end of the pressure-applying movable wing 1133c facing the transmitting unit receiving portion 1104. During the movement of the handle housing 120 in the first direction, at least a portion of the pressure-applying movable wing 1133c can enter the wing receiving hole 1231, and subsequently, if the handle housing 120 attempts to move in a direction opposite to the first direction, the blocking member 1231' abuts against the fixing auxiliary groove 1133c' and is supported, thereby restricting the movement of the handle housing 120 in the direction opposite to the first direction. Since the fixing auxiliary groove 1133c' assists the blocking member 1231' in a more precise position against the pressure-applying movable wing 1133c, the fixing auxiliary groove 1133c' can preferably be recessed at a position corresponding to the blocking member 1231'. Furthermore, although... Figure 17 (c) shows the case where the fixed auxiliary groove 1133c' is recessed in the region adjacent to the partition wall 1112, but it may also include the case where the fixed auxiliary groove 1133c' is recessed in the central region of one end of the pressure moving wing 1133c.

[0127] like Figure 18 As shown in (a) and (b), an auxiliary ramp 1132d' is provided on a surface of the pressure-applying moving main body 1132d facing the partition wall 1112. The auxiliary ramp 1132d' can be arranged obliquely to approach the partition wall 1112 along a first direction. The auxiliary ramp 1132d' can be set to have a steeper angle relative to the second direction than the pressure-applying moving ramp 1133e. When the handle housing 120 moves along the first direction, the front end of the push arm 1230 applies pressure to the pressure-applying moving wing 1133d, causing the front end of the fixing protrusion 1137d to exit from the fixing groove 1340, and as the handle housing 120 continues to move along the first direction, at least one end of the pressure-applying moving wing 1133d can enter the wing receiving hole 1231. Because the auxiliary inclined surface 1132d' is arranged at an angle close to the partition wall 1112 along the first direction, the fixing part 1130 is arranged at a position radially spaced from the first moving space 1111 compared to the initial position. This minimizes the possibility of the front end of the fixing protrusion 1137d re-entering the first moving space 1111. In other words, since the surface of the pressure moving main body 1132d facing the partition wall 1112 is provided with the auxiliary inclined surface 1132d' close to the partition wall 1112 along the first direction, the movement interference inside the first moving space 1111 that may occur after the front end of the fixing protrusion 1137d re-enters the first moving space 1111 after exiting the fixing groove 1340 can be effectively eliminated.

[0128] As described below, a fixing groove 1340 with a shape corresponding to the fixing protrusion 1137 can be recessed into one surface of the sensor unit carrier body 1310. Because the fixing groove 1340 is recessed, a space for accommodating at least a portion of the fixing portion 1130 can be formed. When the position of the sensor unit carrier 130 is defined as the initial position when the user has not pressed the handle housing 120 (i.e., the state where the percutaneous sensor member 330 has not been triggered and subcutaneously inserted), and the position of the sensor unit carrier 130 is defined as the insertion position when the user has pressed the handle housing 120 (i.e., the state where the percutaneous sensor member 330 has been triggered and subcutaneously inserted), the fixing groove 1340 is preferably recessed into one surface of the sensor unit carrier body 1310, such that the fixing groove 1340 and the fixing protrusion 1137 of the sensor unit carrier 130 in the initial position are positioned at corresponding locations. Furthermore, after the applicator 10 is assembled, the handle housing 120 can be positioned at a first position, and after the transdermal sensor component 330 is triggered, it can be positioned at a second position. As the handle housing 120 moves from the first position to the second position, the sensor unit carrier 130 can move from the initial position to the insertion position in conjunction with the sensor unit carrier 130. During the process of inserting the sensor unit carrier body 1310 into the first moving space 1111 to assemble the applicator 10, the fixing protrusion 1137 abuts against a surface of the sensor unit carrier body 1310, causing the bracket 1134 to twist outward, and the fixing part 1130 remains in a state of moving away from the first moving space 1111. Then, when the sensor unit carrier body 1310 is pushed into the first moving space 1111 along the first direction until the fixing protrusion 1137 corresponds to the fixing groove 1340, the front end of the fixing protrusion 1137 is introduced and arranged inside the fixing groove 1340, and the bracket 1134 returns to the state before the twisting deformation.

[0129] As the front end of the fixing protrusion 1137 is introduced into the interior of the fixing groove 1340, any movement of the sensor unit carrier 130 in the first direction or in the opposite direction can be restricted. With the front end of the fixing protrusion 1137 accommodated inside the fixing groove 1340, the connection operation between the handle housing 120 and the main housing 110 can then be performed.

[0130] During the process of connecting the handle housing 120 to the main housing 110, the front end of the push arm 1230 provided in the handle housing 120 can abut against the pressure moving ramp 1133' of the pressure moving wing 1133. As the front end of the push arm 1230 moves along the first direction while abutting against the pressure moving ramp 1133' and applies pressure to the pressure moving wing 1133, the bracket 1134 twists and deforms outward, so that the pressure moving part 1131 can be pushed away from the sensor unit carrier main body 1310.

[0131] As the pressure-applying moving part 1131 is pushed away from the sensor unit carrier body 1310, the front end of the fixing protrusion 1137 moves to a position separated from the fixing groove 1340, thereby releasing the restriction of the fixing part 1130 on the arbitrary movement of the sensor unit carrier 130. Since the applicator 10 can be assembled while the sensor unit carrier 130 is held in its initial position by the fixing part 1130, the work efficiency during the assembly of the applicator 10 can be improved more effectively.

[0132] Furthermore, the above description uses the example of the front end of the push arm 1230 pressing one end of the fixing part 1130 during the assembly of the applicator 10, causing the fixing protrusion 1137 to exit from the fixing groove 1340. However, it is also possible for the front end of the push arm 1230 to press one end of the fixing part 1130 during the triggering of the transdermal sensor component 330, causing the fixing protrusion 1137 to exit from the fixing groove 1340. That is, it can include the following situation: during the assembly of the applicator 10, the front end of the push arm 1230 is positioned adjacent to or abutting against one end of the fixing part 1130, and during the process of the user pressing the handle housing 120, causing the handle housing 120 to move from the first position to the second position, the front end of the push arm 1230 applies pressure to one end of the fixing part 1130, thereby causing the fixing protrusion 1137 to exit from the fixing groove 1340.

[0133] The main housing 110 may have a transmitting unit receiving portion 1104 at its closed end opposite to the second opening 1101, capable of accommodating the transmitting unit 40. The transmitting unit receiving portion 1104 may be formed in a shape that is recessed from the outside of the main housing 110 into the second internal space 1102. Preferably, the transmitting unit receiving portion 1104 may be formed in a shape that corresponds to the shape of the transmitting unit housing 410, so that the transmitting unit housing 410 can be accommodated inside it. Preferably, the transmitting unit receiving portion 1104 may be formed in a recessed depth such that when one end of the applicator 10 is in close contact with the skin while the transmitting unit 40 is accommodated in the transmitting unit receiving portion 1104, the adhesive member 430 provided on the transmitting unit 40 can be attached to the skin.

[0134] A third opening 1106 connecting the transmitting unit receiving portion 1104 and the first moving space 1111 can penetrate one end of the main housing 110 where the transmitting unit receiving portion 1104 is formed. During the insertion of the percutaneous sensor component 330 subcutaneously, the sensor unit 30, which has moved in the first moving space 1111 along the first direction, can pass through the third opening 1106 and be transferred to the mounting slot 412 of the transmitting unit 40 received in the transmitting unit receiving portion 1104.

[0135] A transmitting unit support portion 1160 may be provided on both sides of the transmitting unit receiving portion 1104 to prevent the transmitting unit 40 from arbitrarily detaching from the transmitting unit receiving portion 1104. A support hook receiving space 1161 may be provided on both sides of the transmitting unit receiving portion 1104, and the support hook receiving space 1161 extends through the closed end of the main body housing 110. A transmitting unit support hook 1162, configured to support the transmitting unit 40, may be arranged to be received in the support hook receiving space 1161. The transmitting unit support hook 1162 may be supported by a support hook access portion 1166, which extends from the end of the main body housing 110 forming the support hook receiving space 1161 and connects to the two side ends of the transmitting unit support hook 1162. Since the transmitting unit support hook 1162 is connected to the support hook access portion 1166 extending from the end of the main housing 110 and arranged in the support hook receiving space 1161, when an external force is applied to the transmitting unit support hook 1162, the support hook access portion 1166 may undergo torsional deformation, thereby changing the position of the transmitting unit support hook 1162.

[0136] The transmitting unit support hook 1162 may include a hook portion 1164 protruding in the direction toward the transmitting unit receiving portion 1104 and a pressure receiving portion 1165 protruding in the opposite direction to the transmitting unit receiving portion 1104. The front end of the hook portion 1164 may be inserted into the transmitting unit housing groove 417 of the transmitting unit 40 received in the transmitting unit receiving portion 1104. The transmitting unit 40 received in the transmitting unit receiving portion 1104 may be supported by the hook portion 1164 whose front end is inserted into the transmitting unit housing groove 417 to prevent it from arbitrarily disengaging from the transmitting unit receiving portion 1104. A pressure receiving slope 1165a may be formed on the pressure receiving portion 1165, which is inclinedly arranged to be close to the transmitting unit receiving portion 1104 along a first direction. The extension arm pressing portion 1326 of the sensor unit carrier 130, described later, can apply pressure to the inclined surface 1165a of the pressure receiving portion, thereby causing the transmitting unit support hook 1162 to rotate in a direction away from the transmitting unit receiving portion 1104. That is, during the insertion of the percutaneous sensor member 330 under the skin, the sensor unit carrier 130 moves together with the sensor unit 30 in the first direction. At the same time as the sensor unit 30 is transferred from the sensor unit carrier 130 to the transmitting unit 40, or at a time point slightly earlier than the time point when the sensor unit 30 is transferred from the sensor unit carrier 130 to the transmitting unit 40, the extension arm pressing portion 1326 applies pressure to the inclined surface 1165a of the pressure receiving portion, thereby releasing the restriction on the movement of the transmitting unit 40 by the abutment portion 1164. Furthermore, during the manufacturing of the applicator assembly 1, when the dispensing unit 40 is placed into the dispensing unit receiving portion 1104, the dispensing unit support hook 1162 is pressed by the dispensing unit housing 410, causing it to twist and move in a direction spaced apart from the dispensing unit receiving portion 1104. When the dispensing unit 40 is fully installed in the dispensing unit receiving portion 1104, the twisted dispensing support hook 1162 can return to its original state, and the front end of the abutment portion 1164 can be arranged inside the dispensing unit housing groove 417. Since the dispensing unit support portion 1160 is configured to release the movement restriction of the dispensing unit 40 only when the worker or user intentionally moves it during the assembly or use of the applicator assembly 1, the convenience of the assembly operation and the ease of use of the applicator assembly 1 can be improved more effectively.

[0137] On any one or more inner surfaces of the partition wall 1112 forming the first moving space 1111, a clamping arm guide groove 1120 extending in a first direction may be formed in an outwardly recessed shape. The clamping arm 1422 of the needle carrier 140, described later, may be arranged in the clamping arm guide groove 1120 to guide the moving direction of the needle carrier 140. A stepped portion 1121 is formed at the center of the clamping arm guide groove 1120. This stepped portion 1121 protrudes at a height approximately corresponding to the surface of the partition wall 1112 where the clamping arm guide groove 1120 is formed, and 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. The first stepped inclined surface 1123 may be arranged obliquely in a shape close to the first moving space 1111 in the first direction, and the second stepped inclined surface 1124 may be arranged obliquely in a shape away from the first moving space 1111 in the first direction.

[0138] When assembling the applicator assembly 1, the needle carrier 140 enters the first moving space 1111 along the first direction, and the needle carrier 140 can move to an initial position with the clamping arm 1422 arranged in the clamping arm guide groove 1120. When the needle carrier 140 is arranged in the initial position, the clamping arm protrusion 1424 formed on the clamping arm 1422 can pass through the first stepped inclined surface 1123 or be located just before passing through the first stepped inclined surface 1123. Thereafter, as the needle carrier 140 moves further along the first direction, the clamping arm protrusion 1424 can come into close contact with the stepped portion 1121 and be pressed inward, and during the movement of the needle carrier 140, the sensor unit 30 can remain more firmly fixed to the inwardly pressed clamping arm 1422. Furthermore, as the needle carrier 140 moves further along the first direction to the insertion position, the clamping arm protrusion 1424 passes through the second stepped inclined surface 1124. As the clamping arm protrusion 1424 passes through the second stepped inclined surface 1124, the pressure exerted by the step portion 1121 on the clamping arm protrusion 1424 can be released. That is, during the insertion of the percutaneous sensor component 330 subcutaneously, the pressure exerted by the step portion 1121 on the clamping arm protrusion 1424 can be released either simultaneously with or before the sensor unit 30 is transferred to the mounting slot 412 of the transmitting unit 40. This not only effectively prevents the sensor unit 30 from detaching from the designated position inside the applicator 10 during the insertion of the percutaneous sensor component 330 subcutaneously, but also effectively prevents the sensor unit 30 from being dragged by the clamping arm 1422 in a direction opposite to the first direction after the percutaneous sensor component 330 is inserted subcutaneously.

[0139] Sensor unit carrier

[0140] Figure 19 and Figure 20This is a perspective view showing an exemplary embodiment of the sensor unit carrier 130.

[0141] The sensor unit carrier 130 can be disposed inside the applicator assembly 1 such that it moves along a first direction together with the needle carrier 140 and the sensor unit 30 during the insertion of the percutaneous sensor member 330 subcutaneously. After the percutaneous sensor member 330 is inserted subcutaneously, the needle carrier 140 can move to a retracted position, causing the needle body 1402 to withdraw from the skin, while the sensor unit carrier 130 remains in the inserted position.

[0142] The sensor unit carrier 130 may include a sensor unit carrier body 1310 constituting the skeleton of the sensor unit carrier 130, and the sensor unit carrier body 1310 may have a second movement space 1312 open at the front. After the percutaneous sensor member 330 is inserted subcutaneously, the needle carrier 140 can move to the retracted position through the second movement space 1312. At one end of the sensor unit carrier body 1310 adjacent to the third opening 1106 formed in the main body housing 110, a fourth opening 1312 may be formed to communicate with the outside and the second movement space 1312. The needle body 1402 may protrude toward the outside of the sensor unit carrier body 1310 through the fourth opening 1312. The side of the sensor unit carrier body 1310 facing the third opening 1106 is provided with a fixing protrusion 1317 in the shape of protruding toward the third opening 1106, and the sensor unit 30 can be more firmly fixed to the sensor unit carrier 130 by inserting the front end of the fixing protrusion 1317 into the fixing groove 317 of the sensor unit 30.

[0143] At the corner of the side end of the sensor unit carrier body 1310, a carrier guide protrusion 1310a, protruding outward, extends along a first direction. The front end of the carrier guide protrusion 1310a is disposed inside the carrier guide groove 1114 formed on the columnar member 1110. The movement direction of the sensor unit carrier body 1310 moving along the first direction can be guided by the carrier guide protrusion 1310a and the carrier guide groove 1114. A needle carrier guide protrusion 1313 can be provided on the inner surface of the sensor unit carrier body 1310 forming the second moving space 1312. The needle carrier guide protrusion 1313 is formed to protrude from the inner surface of the sensor unit carrier body 1310 toward the center of the second moving space 1312 and extend along the first direction. The front end of the needle carrier guide protrusion 1313 is disposed inside the needle carrier guide groove 1415 formed in the needle carrier body 1410, which will be described later, and the movement direction of the needle carrier 140, which moves in a direction opposite to the first direction, can be guided by the needle carrier guide protrusion 1313 and the needle carrier guide groove 1415.

[0144] A sliding groove 1319 may be disposed on the inner surface of the sensor unit carrier body 1310 adjacent to the handle housing 120. The sliding groove 1319 is formed to be recessed from the inner surface of the front end of the sensor unit carrier body 1310 and extend along a first direction. Preferably, the sliding groove 1319 is formed at a position adjacent to the open front side of the second movement space 1312. A sensor unit carrier stop 1318 may be disposed in the sliding groove 1319. The sensor unit carrier stop 1318 has a stop slope 1318a and a stop limiting surface 1318b formed on it. Since the needle carrier locking member 1434 of the needle carrier 140, described later, remains restricted by the sensor unit carrier stop 1318, the needle carrier 140 can move together with the sensor unit carrier 130 along the first direction during the insertion of the percutaneous sensor member 330 subcutaneously. The stop limiting surface 1318b may be formed in a direction substantially parallel to the second direction, and the stop inclined surface 1318a may be arranged at an angle such that it approaches the sliding groove 1319 from the protruding end of the stop limiting surface 1318b in a direction opposite to the first direction.

[0145] The extension arm 1320 may be configured to protrude outward from both outer surfaces of the sensor unit carrier body 1310 and extend along a first direction. An extension arm connecting portion 1322 may be disposed between the sensor unit carrier body 1310 and the extension arm 1320. An extension arm guide groove 1324 may be recessed in the extension arm connecting portion 1322 along the first direction. Preferably, the extension arm guide groove 1324 may be formed in a position and shape corresponding to the carrier slit 1117 of the columnar member 1110. During the process of the sensor unit carrier body 1310 moving along the first direction to insert the percutaneous sensor member 330 subcutaneously, the extension arm connecting portion 1322 with the extension arm guide groove 1324 is introduced into the carrier slit 1117 of the columnar member 1110. This not only guides the movement direction of the sensor unit carrier 130 moving along the first direction through the carrier slit 1117 and the extension arm guide groove 1324, but also eliminates interference from the columnar member 1110 on the first-direction movement of the sensor unit carrier 130.

[0146] The second acceleration locking member 1328 may be disposed on a surface of the extension arm 1320 facing the sensor unit carrier body 1310 and formed to protrude toward the sensor unit carrier body 1310. The second acceleration locking member 1328 may include: a support surface 1328b formed in a direction substantially parallel to the second direction; and an inclined surface 1328a arranged obliquely to gradually approach a surface of the extension arm 1320 from the protruding end of the support surface 1328b along the first direction. The second acceleration locking member 1328 can prevent the user from arbitrarily triggering the applicator 10 under unintended circumstances by interacting with the first acceleration locking member 1118 disposed on the main body housing 110, can provide sufficient acceleration conditions for the needle body 1402 when the percutaneous sensor member 330 is inserted subcutaneously, and can prevent the sensor unit carrier 130 from moving in a direction opposite to the first direction after the percutaneous sensor member 330 is inserted subcutaneously.

[0147] When the sensor unit carrier 130 is in its initial position, the inclined surfaces 1119a of the first acceleration locking member 1118 and 1328a of the second acceleration locking member 1328 are spaced apart or abutted against each other. When the user presses the handle housing 120 in the first direction, causing the sensor unit carrier 130 to move in the first direction, the inclined surfaces 1119a of the first acceleration locking member 1118 and 1328a of the second acceleration locking member 1328 rub against each other and move while abutting against each other. At this time, the extension arm 1320 may twist and deform outward. Subsequently, as the sensor unit carrier 130 moves in the first direction, the abutment between the inclined surfaces 1328a of the second acceleration locking member 1328 and 1119a of the first acceleration locking member 1118 can be released, and the position can be switched to a state where the support surfaces 1119b of the first acceleration locking member 1118 and 1328b of the second acceleration locking member 1328 face each other. After switching to a state where the support surfaces 1119b of the first acceleration locking member 1118 and 1328b of the second acceleration locking member 1328 face each other, the percutaneous sensor member 330 is inserted subcutaneously. After the percutaneous sensor member 330 is inserted subcutaneously, the movement of the sensor unit carrier 130 in the direction opposite to the first direction can be restricted by the support surfaces 1119b of the first acceleration locking member 1118 and 1328b of the second acceleration locking member 1328 facing each other. The above describes, with respect to the shapes of the first acceleration locking member 1118 and the second acceleration locking member 1328, an exemplary locking member structure having a wedge-shaped cross-section with inclined surfaces 1119a, 1328a and support surfaces 1119b, 1328b. However, the shapes of the first acceleration locking member 1118 and the second acceleration locking member 1328 are not necessarily limited to this, and can be applied in various variations, as long as the structure can prevent the user from arbitrarily triggering the applicator 10 under unintended circumstances through interaction, provide sufficient acceleration conditions for the needle body 1402 when the transdermal sensor member 330 is inserted subcutaneously, and prevent the sensor unit carrier 130 from moving in the opposite direction to the first direction after the transdermal sensor member 330 is inserted subcutaneously.

[0148] A bridging member 1330 may be disposed between the extension arm 1320 and the sensor unit carrier body 1310. The bridging member 1330 may be configured such that one end is connected to a side of the sensor unit carrier body 1310 and the surface of the extension arm 1320 facing the sensor unit carrier body 1310, respectively. The bridging member 1330 is preferably formed at a position corresponding to the bridging member pressure portion 1116 of the columnar member 1110, and one or more relatively thin weak portions 1332 may be formed on the bridging member 1330. During the process of the user pressing the handle housing 120 in the first direction to move the sensor unit carrier 130 in the first direction, the sensor unit carrier 130 can only continue to move to the insertion position if the bridging member 1330 abutting against the bridging member pressure portion 1116 breaks. The weak point 1332 can refer to the area where the bridging member 1330 is pre-intended to fracture when pressure is applied by the bridging member pressure section 1116, and is preferably designed so that the weak point 1332 will only fracture when the force applied by the user pressing the handle housing 120 to insert the transcutaneous sensor member 330 subcutaneously is applied to the bridging member 1330. Here, the force applied by the user pressing the handle housing 120 to insert the transcutaneous sensor member 330 subcutaneously does not refer to the force applied during the assembly and transportation of the applicator assembly 1, but rather to the force applied by the user of the applicator assembly 1 to the handle housing 120 in order to insert the transcutaneous sensor member 330 subcutaneously. In addition, although an area with a thickness thinner than the bridging member 1330 has been described as an example of the weak point 1332, the weak point 1332 is not necessarily limited to a relatively thin structure. The weak point 1332 can refer to an area whose fracture strength is lower than that of the entire bridging member 1330 by using different materials or by adopting a fragile structure. Through the interaction of the bridging member 1330 and the bridging pressure application part 1116, not only can the applicator 10 be prevented from being arbitrarily triggered by the user without their consent, but sufficient acceleration conditions can also be provided to the needle body 1402 when the percutaneous sensor member 330 is inserted subcutaneously. Furthermore, the above description uses the case where the bridging member 1330 is disposed on the sensor unit carrier 130 and the bridging pressure application part 1116 is disposed at the front end of the spacer wall 1112 as an example, but it may also include the case where the bridging member structure is disposed on the spacer wall 1112 and the pressure application part for breaking the bridging member structure is disposed on the sensor unit carrier 130.

[0149] An extension arm pressing portion 1326 with a beveled surface 1326a protruding along a first direction may be formed at the end of the extension arm 1320. When the sensor unit carrier 130 moves along the first direction and is positioned in the insertion position, the extension arm pressing portion 1326 applies pressure to the pressure receiving portion 1165 provided on the transmitting unit support hook 1162. As the pressure receiving portion 1165 is pressed by the extension arm pressing portion 1326, the transmitting unit support hook 1162 twists and deforms outward away from the transmitting unit 40, thereby releasing the movement restriction of the abutment portion 1164 on the transmitting unit 40. The beveled surface 1326a formed on the extension arm pressing portion 1326 and the beveled surface 1165a formed on the pressure receiving portion 1165 are not particularly restricted, as long as their shapes can cause the transmitting unit support hook 1162 to twist and deform outward away from the transmitting unit 40 when the pressure receiving portion 1165 is pressed by the extension arm pressing portion 1326. The extension arm pressing part 1326 can preferably be formed at a position that can apply pressure to the pressing part 1165 at the same time as the sensor unit carrier 130 reaches the insertion position or before the sensor unit carrier 130 is about to reach the insertion position.

[0150] At one end of the second moving space 1312 adjacent to the handle housing 120, a sensor unit carrier ring 1316 may be provided, on which an elastic member 150, described later, is fixedly arranged. Additionally, on a surface of the sensor unit carrier body 1310 opposite to the second moving space 1312, a fixing groove 1340 with a shape corresponding to the fixing protrusion 1137 may be recessed, and this fixing groove 1340 may preferably be recessed at the position corresponding to the fixing protrusion 1137 when the sensor unit carrier 130 is in the initial position.

[0151] needle carrier

[0152] Figure 21 This is a perspective view illustrating the connection relationship of the needle carrier 140. Figure 22 This is a perspective view showing an exemplary embodiment of the needle carrier 140, and Figure 23 This is an exemplary front view showing the connection relationship between the needle carrier 140 and the sensor unit carrier 130.

[0153] The needle carrier 140 can be configured such that it has a needle 1401 for inserting the percutaneous sensor member 330 under the skin, and moves together with the sensor unit carrier 130 and the sensor unit 30 in a first direction. After the percutaneous sensor member 330 is inserted under the skin, it moves in a second movement space 1312 in a direction opposite to the first direction, thereby removing the needle body 1402 from under the skin.

[0154] The needle carrier 140 may include a needle 1401 and a needle carrier body 1410. The needle carrier body 1410 may be configured to fix the needle 1401 and move together with the needle 1401. The needle 1401 may include a needle body 1402 and a needle holder 1403. One end of the needle body 1402 is inserted subcutaneously for subcutaneous insertion of the percutaneous sensor member 330, and the needle body 1402 is used to fix the needle body 1402. The needle body 1402 may have an opening that opens radially outward based on the extension direction of the needle body 1402, and the opening may be formed to extend along a first direction. The end of the needle body 1402 adjacent to the transmitting unit receiving portion 1104 may be open. The end of the needle body 1402 adjacent to the transmitting unit receiving portion 1104 may be angled. The end of the needle carrier body 1410 facing the fourth opening 1312 may be recessed to form a needle holder insertion groove 1412 for the needle holder 1403 to be inserted and fixed. The needle 1401 can be fixed to the needle carrier body 1410 by inserting and fixing the needle holder 1403 into the needle holder insertion slot 1412. When the needle carrier 140 is in the initial position and the insertion position, the needle body 1402 can be withdrawn to the outside through the fourth opening 1312. When the needle carrier 140 returns to the retracted position, the needle body 1402 can be entered through the fourth opening 1312 and arranged inside the second moving space 1312.

[0155] A needle guide groove 1415 may be provided on one side of the needle carrier body 1410. The needle guide groove 1415 has a shape that is recessed from one side of the needle carrier body 1410 and extends along a first direction. The front end of the aforementioned needle carrier guide protrusion 1313 is arranged inside the needle guide groove 1415, and the movement of the needle carrier 140 in a direction opposite to the first direction can be guided by the interaction between the needle carrier guide protrusion 1313 and the needle guide groove 1415.

[0156] The needle carrier wing bodies 1430 may be arranged in pairs, each having a shape extending from both ends of the needle carrier body 1410 in a direction opposite to a first direction. The needle carrier wing bodies 1430 may be configured to torsionally deform when an external force is applied and to return to their original shape after the external force is removed. The front end of the needle carrier wing body 1430 may be provided with a needle carrier locking member 1434 and a trigger 1432. The needle carrier locking member 1434 may include a limiting surface 1434b and a ramp 1434a, the limiting surface 1434b being formed in a direction substantially parallel to a second direction, and the ramp 1434a being obliquely arranged to extend from the protruding end of the limiting surface 1434b towards the needle carrier wing body 1430 in the first direction. The trigger 1432 may have a shape that protrudes more outwardly than the needle carrier locking member 1434. The trigger 1432 may have a trigger ramp 1433, such that the cross-section of the trigger 1432 decreases along the first direction. The trigger 1432 may preferably be arranged outside the second moving space 1312.

[0157] Before operating the applicator assembly 1 or while the needle carrier 140 moves in the first direction, the limiting surface 1434b of the needle carrier locking member 1434 remains abutting against the stopping limiting surface 1318b of the sensor unit carrier stop member 1318, thereby restricting the relative movement of the needle carrier 140 relative to the sensor unit carrier 130. That is, with the limiting surface 1434b of the needle carrier locking member 1434 abutting against the stopping limiting surface 1318b of the sensor unit carrier stop member 1318, the needle carrier 140 cannot move independently, and can only move together with the sensor unit carrier 130 when the sensor unit carrier 130 moves while being restricted to its position. During the insertion of the percutaneous sensor member 330 subcutaneously, when the needle carrier 140 moves to a position adjacent to the insertion location, the trigger tilt portion 1433 of the trigger 1432 abuts against the front end of the spacer wall 1112, allowing the needle carrier wing body 1430 to twist and deform inward toward the second movement space 1312. As the needle carrier wing body 1430 twists and deforms inward toward the second moving space 1312, the limiting surface 1434b of the needle carrier locking member 1434 can disengage from the stop limiting surface 1318b of the sensor unit carrier stop member 1318. With the release of the stop limiting surface 1318b of the sensor unit carrier stop member 1318, the needle carrier locking member 1434 can pass over the sensor unit carrier stop member 1318, and the needle carrier 140 can move in the opposite direction to the first direction under the elastic force applied by the elastic member 150, thereby reaching the retraction position. To prevent pain caused by excessive insertion of the needle body 1402 into the body B, it is preferable to release the movement restriction of the sensor unit carrier 130 relative to the needle carrier 140 before the sensor unit carrier 130 reaches the insertion position. In this case, even if the needle carrier 140 moves in the opposite direction to the first direction, the sensor unit carrier 130 remains in a state of applying pressure to the sensor unit 30 in the first direction. Therefore, due to the rigidity of the percutaneous sensor member 330 itself, the percutaneous sensor member 330 can be accurately inserted into the desired subcutaneous position.

[0158] Multiple clamping arms 1422 may be configured to extend from the other two side ends of the needle carrier body 1410 along a first direction. The front end of the clamping arm 1422 may be provided with an inwardly protruding clamping portion 1423, and the side end of the sensor unit housing 310 may be clamped by the clamping portion 1423. The clamping arm protrusion 1424 may be formed from a surface of the clamping arm 1422 facing the spacer wall of the columnar member 1110, and when the needle carrier 140 is in the initial position, the clamping arm protrusion 1424 may be arranged inside the clamping arm guide groove 1120 before passing the first stepped inclined surface 1123, or may pass through the first stepped inclined surface 1123 and remain in close contact with and pressurized by the stepped portion 1121. During the insertion of the percutaneous sensor component 330 into the subcutaneous tissue, the clamping arm protrusion 1424 passes through the second step inclined surface 1124, and the tight contact and pressure of the step portion 1121 on the clamping arm protrusion 1424 are released, allowing each clamping arm 1422 to be slightly extended outward, thereby transmitting the sensor unit 30 to the transmitting unit 40.

[0159] One end of the needle carrier body 1410 facing the sensor unit carrier ring 1316 may be provided with a needle carrier ring 1414, and the other end of the elastic member 150, which is connected to the sensor unit carrier ring 1316, may be connected to the needle carrier ring 1414. The application of the elastic member 150 is not limited, as long as it can provide driving force when the needle carrier 140 moves in a direction opposite to the first direction, but a tension spring is preferred.

[0160] build

[0161] Figure 24 This is an exploded perspective view showing an exemplary embodiment of the cover 50. Figure 25 It is along Figure 24 The cross-sectional view of cover 50 taken along the E-E' direction, and Figures 26 to 28 This is a partially enlarged cross-sectional view showing an exemplary embodiment of the applicator assembly 1 with the cover 50 applied.

[0162] The cover 50 is detachably fixed to one end of the applicator 10. The applicator assembly 1 includes the cover 50, thus effectively preventing the applicator 10 from being accidentally or arbitrarily triggered during the manufacture, distribution, storage and use of the applicator assembly 1, or preventing external contaminants or moisture from entering the interior of the applicator assembly 1.

[0163] The cover 50 may include a cover housing 501 that constitutes the appearance of the cover 50. An accommodating space 503 may be formed inside the cover housing 501, which communicates with the outside through a fifth opening 502 formed at one end of the cover housing 501. A threaded portion 540 may be provided on the inner surface of the end of the cover housing 501 with the fifth opening 502, the shape of which corresponds to the shape of the threaded portion 1240 formed in the handle housing 120. With the threaded portion 1240 formed in the handle housing 120 and the threaded portion 540 formed in the cover housing 501 threadedly connected, the cover 50 can be detachably threaded to one end of the handle housing 120. A plurality of clamping grooves 505 may be recessed on the outer surface of the cover housing 501 to facilitate operation or use by workers or users. Furthermore, although the cover housing 501 shown in the figure is cup-shaped, the shape of the cover housing 501 of the present invention is not necessarily limited to this. As long as its shape can protect the interior of the applicator 10 and dehumidify, the shape of the cover housing 501 can be applied in various modified forms. However, since the end of the cover housing 501 with the threaded portion 540 is intended to be threadedly connected to the threaded portion 1240 formed on the handle housing 120, the end of the cover housing 501 with the threaded portion 540 can preferably be set as a cylindrical shape corresponding to the end of the handle housing 120.

[0164] The closed end of the cover housing 501 facing the fifth opening 502 may be provided with a receiving groove 504 that is recessed from the outside toward the receiving space 503. The other end of the cover housing 501 forming the receiving groove 504 may be formed with a plurality of ventilation holes 507 communicating between the receiving groove 504 and the receiving space 503. In the receiving groove 504, a first sealing member 510, a desiccant 512, and a second sealing member 514 are arranged sequentially from one side of the ventilation holes 507 outwards. The first sealing member 510 may preferably be made of a breathable but moisture-proof material; as a non-limiting example, Tyvek material from DuPont may be used. The first sealing member 510 can effectively prevent moisture from entering the receiving space 503. The desiccant 512 may preferably be made of a material with dehumidifying properties used in electronic or medical devices. The desiccant 512 can remove moisture that has entered the receiving space 503. The second sealing member 514 can be arranged relative to the external sealing receiving groove 504 and can be made of a material that prevents moisture and external contaminants from penetrating. As a non-limiting example, the second sealing member 514 can be made of aluminum foil. Since the first sealing member 510, the desiccant 512 and the second sealing member 514 are arranged sequentially in the receiving groove 504 that communicates with the receiving space 503 through the ventilation hole 507, not only can moisture entering the receiving space 503 be effectively removed, but external contaminants or moisture can also be effectively prevented from entering the receiving space 503.

[0165] like Figure 26As shown, the front end of the cover housing 501 may be provided with a pair of sealing members 508a and 508b arranged in a ring and upright, and a sealing member 1243 protrudes from one surface of the locking protrusion 1242 corresponding to the front end of the cover housing 501. When the threaded portion 540 formed on the cover housing 501 and the threaded portion 1240 formed on the handle housing 120 are threadedly connected to each other, so that the cover 50 is connected to one end of the handle housing 120, the sealing members 508a and 508b are in close contact with the sealing member 1243 and apply pressure, thereby effectively preventing external contaminants or moisture from entering the space between the handle housing 120 and the cover 50. The sealing member 1243 and the sealing members 508a and 508b can be integrally injection molded with the handle housing 120 and the cover housing 501, or they can be made of self-elastic materials such as rubber or silicone.

[0166] The following will refer to Figures 29 to 48 The assembly and operation process of the applicator 10 and the applicator assembly 1 are described in more detail.

[0167] Exemplary embodiments regarding the function of the fixing part

[0168] Figure 29 This is a partial cross-sectional view showing an exemplary embodiment of the sensor unit carrier 130 being attached to the main housing 110 during the assembly of the applicator assembly 1. Figure 30 and Figure 31 This is a partial cross-sectional view illustrating an exemplary embodiment of the process of attaching the handle housing 120 to the main housing 110 to which the sensor unit carrier 130 is attached during the assembly of the applicator assembly 1. Figure 32 This is an enlarged cross-sectional view showing an exemplary embodiment in which the front end of the fixing protrusion 1137 is inserted into the fixing groove 1340 during the assembly of the applicator assembly 1. Figures 33 to 35 This is an enlarged cross-sectional view showing an exemplary embodiment of the interaction between the push arm 1230 and the fixing part 1130 during the assembly and operation of the applicator assembly 1.

[0169] like Figure 29 and Figure 32As shown, during the assembly of the main housing 110 and the sensor unit carrier 130, the sensor unit carrier main body 1310 can be fitted into the columnar member 1110 forming the first moving space 1111. During the fitting of the sensor unit carrier main body 1310 into the columnar member 1110, the fixing protrusion 1137 abuts against a surface of the sensor unit carrier main body 1310, and the bracket 1134 can maintain an outwardly twisted deformation state. That is, the front end of the bracket 1134, where the fixing protrusion 1137 and the pressure-applying moving extension 1136 are arranged, can maintain a twisted deformation state in a direction away from the first moving space 1111. As the sensor unit carrier main body 1310 moves along the first direction, the bracket 1134 maintains an outwardly twisted deformation state, and when the fixing groove 1340 formed on the sensor unit carrier main body 1310 reaches the position corresponding to the fixing protrusion 1137, the bracket 1134 can return from the twisted deformation state to its original state. In other words, as the front end of the fixed protrusion 1137 enters the fixed groove 1340, the pressure moving part 1131 moves toward the sensor unit carrier body 1310, and the bracket 1134 can also recover from the torsional deformation.

[0170] As the front end of the fixed protrusion 1137 enters the fixed groove 1340, the movement of the sensor unit carrier 130 in the first direction can be restricted. During the assembly of the applicator assembly 1, the worker can identify whether the front end of the fixed protrusion 1137 has properly entered the fixed groove 1340 by the sound of the parts colliding with each other or by the sensation transmitted to the fingertips.

[0171] Multiple fixing portions 1130 can be provided, or multiple fixing protrusions 1137 can be provided on one fixing portion 1130, and fixing grooves 1340 can be recessed into a surface of the sensor unit carrier body 1310 with corresponding shapes and numbers. In order to reduce friction during the process of at least one end of the fixing protrusion 1137 entering into and exiting the fixing groove 1340, the fixing groove 1340 and / or the fixing protrusion 1137 can be provided with bevels. The fixing groove 1340 can include not only the case of being recessed into a surface of the sensor unit carrier body 1310, but also the case of being formed through a surface of the sensor unit carrier body 1310.

[0172] Subsequently, the worker can perform the operation of connecting the handle housing 120 to the main housing 110 to which the sensor unit carrier 130 is attached. When connecting the handle housing 120 to the main housing 110 to which the sensor unit carrier 130 is attached, the sensor unit carrier 130 may be pressed by the handle housing 120 which is inserted for assembly, resulting in arbitrary triggering or the sensor unit carrier 130 dislodging from its initial position. However, when the handle housing 120 is assembled with the front end of the fixing protrusion 1137 inserted into the fixing groove 1340, arbitrary triggering of the applicator 10 or displacement of the sensor unit carrier 130 can be effectively prevented. Figures 29 to 35 The diagram shows an odd number of push arms 1230 and fixing parts 1130, but the push arms 1230 and fixing parts 1130 can also be arranged in multiple units corresponding to each other. In this case, the stability of the fixation between the main body housing 110 and the sensor unit carrier 130 can be improved more effectively before connecting the handle housing 120. Furthermore, when connecting the main body housing 110 and the handle housing 120, the position of the push arms 1230 and fixing parts 1130 can be easily inspected visually by the worker, thereby further improving the ease of assembly of the main body housing 110 and the handle housing 120. During the connection of the handle housing 120 to the main body housing 110, at least one surface of the sensor unit carrier 130 can be positioned to abut against the inner surface of the carrier fixing baffle 1207. At least one end of the fixing protrusion 1137 is disposed inside the fixing groove 1340, such that the handle housing 120 and the main housing 110 are connected when the movement of the sensor unit carrier 130 in the first direction is restricted, thus allowing one end of the sensor unit carrier 130 to accurately enter the interior of the carrier fixing baffle 1207. Figure 30 , Figure 31 and Figure 33As shown, during the connection of the handle housing 120 to the main housing 110 to which the sensor unit carrier 130 is already connected, the front end of the push arm 1230 provided on the handle housing 120 moves to a position abutting against the pressure moving ramp 1133' of the pressure moving wing 1133. As the handle housing 120 is assembled, the front end of the push arm 1230 moves along a first direction while abutting against the pressure moving ramp 1133', applying pressure to the pressure moving wing 1133, and the bracket 1134 twists and deforms outwards, thereby pushing the pressure moving part 1131 away from the sensor unit carrier main body 1310. As the pressure moving part 1131 is pushed away from the sensor unit carrier main body 1310, the front end of the fixing protrusion 1137 can retract from the fixing groove 1340. As the front end of the fixing protrusion 1137 exits from the fixing groove 1340, the restriction of the fixing part 1130 on the arbitrary movement of the sensor unit carrier 130 can be released, and the sensor unit carrier 130 can remain in a state where it can move independently of the fixing part 1130. Furthermore, although Figure 31 The illustration shows the sensor unit carrier 130 fully abutting against the inner surface of the handle housing 120 after the applicator 10 is assembled. However, it may also include a situation where, even after the applicator 10 is assembled, the front end of the sensor unit carrier 130 remains a certain distance away from the inner surface of the handle housing 120. Figure 30 As shown. In this case, as the user presses the handle housing 120, causing the handle housing 120 to move from the first position to the second position, the distance between the front end of the sensor unit carrier 130 and the handle housing 120 can be maintained or reduced, and a buffer can be provided in case that excessive pressure is applied to the handle housing 120 during the operation of the applicator assembly 1, and the corresponding pressure is directly transmitted to the transdermal sensor member 330.

[0173] like Figure 34 As shown, after the front end of the fixed protrusion 1137 exits from the fixed groove 1340, as the push arm 1230 continues to move in the first direction, the pressure-applying movable wing 1133 is positioned facing the wing receiving hole 1231, and one end of the pressure-applying movable wing 1133 can enter the wing receiving hole 1231 after passing the blocking member 1231'. That is, when the pressure-applying movable wing 1133 passes the blocking member 1231', the front end of the bracket 1134, which is provided with the fixed protrusion 1137 and the pressure-applying movable extension 1136, twists and deforms in the direction close to the first moving space 1111, thereby allowing at least one end of the pressure-applying movable wing 1133 to be arranged inside the wing receiving hole 1231.

[0174] like Figure 35As shown, when at least one end of the pressure-applying movable wing 1133 is positioned inside the wing receiving hole 1231, even if the push arm 1230 moves in a direction opposite to the first direction, the blocking member 1231' will abut against one end of the pressure-applying movable wing 1133 facing the transmitting unit receiving portion 1104, thereby restricting the push arm 1230 from moving in a direction opposite to the first direction. In other words, after the percutaneous sensor component 330 is inserted subcutaneously, the interaction between the push arm 1230 and the fixing portion 1130 can prevent the handle housing 120 from returning to its initial position, thereby effectively preventing the applicator assembly 1 from being reused.

[0175] Furthermore, the above description uses the example of the front end of the push arm 1230 applying pressure to one end of the fixing part 1130 during the assembly of the applicator 10, causing the fixing protrusion 1137 to exit from the fixing groove 1340. However, it could also include the case where, during the triggering of the transdermal sensor component 330, the front end of the push arm 1230 applies pressure to one end of the fixing part 1130, causing the fixing protrusion 1137 to exit from the fixing groove 1340. Figure 31 Unlike the previous setup, even after the applicator 10 is assembled, the push arm 1230 can be positioned such that its front end is adjacent to one end of the fixing part 1130 but not directly abutting it, or abutting one end of the fixing part 1130 but not to the extent that the fixing protrusion 1137 retracts from the fixing groove 1340, thus applying pressure to the fixing part 1130. In other words, even when the handle housing 120 is in the first position, the push arm 1230 can be positioned such that its front end is spaced a certain distance from one end of the fixing part 1130, or its front end abuts one end of the fixing part 1130. During the process of the user pressing the handle housing 120 to move it from the first position to the second position, the front end of the push arm 1230 applies pressure to one end of the fixing part 1130, allowing the fixing protrusion 1137 to retract from the fixing groove 1340, thereby releasing the restriction of the fixing part 1130 on the arbitrary movement of the sensor unit carrier 130. In this case, the specific process of the fixed protrusion 1137 exiting the fixed groove 1340 corresponds to the process described above, therefore, the specific description therein will be replaced by the above description.

[0176] Exemplary embodiments regarding needle carrier operation

[0177] Figures 36 to 38 This is a partial cross-sectional view of an exemplary embodiment showing the states of the sensor unit carrier 130 moving from the initial position to the insertion position during the operation of the applicator assembly 1, and Figure 35 This is a partial cross-sectional view showing an exemplary embodiment of the needle carrier 140 moving to the retracted position during operation of the applicator assembly 1.

[0178] like Figure 36As shown, during the process of the sensor unit carrier 130 moving from the initial position to the insertion position, the limiting surface 1434b of the needle carrier locking member 1434 remains in contact with the stopping limiting surface 1318b of the sensor unit carrier stop member 1318. Therefore, the needle carrier 140 can remain in a state of being limited by the sensor unit carrier 130 and move together with the sensor unit carrier 130 along the first direction.

[0179] like Figure 37 As shown, when the sensor unit carrier 130 reaches the position adjacent to the insertion position, the trigger ramp 1433 of the trigger 1432 abuts against the front end of the spacer wall 1112. Additionally, as... Figure 38 As shown, as the sensor unit carrier 130 continues to move along the first direction, the needle carrier wing body 1430 twists and deforms inward toward the second movement space 1312. Consequently, the limiting surface 1434b of the needle carrier locking member 1434 and the stopping limiting surface 1318b of the sensor unit carrier stop member 1318 may disengage from their abutting positions. Therefore, the needle carrier locking member 1434 disengages from the restraint of the sensor unit carrier stop member 1318, and the needle carrier 140 can move relative to the sensor unit carrier 130. Furthermore, as... Figure 37 and Figure 38 As shown, the movement restriction of the sensor unit carrier 130 on the needle carrier 140 can be lifted before the sensor unit carrier 130 reaches the insertion position, thereby effectively preventing the needle body 1402 from being over-inserted into the body B and causing side effects.

[0180] like Figure 39 As shown, after the restriction of the sensor unit carrier stop 1318 on the needle carrier locking member 1434 is released, the needle carrier 140 can move relative to the sensor unit carrier 130, and the needle carrier 140 can move to the retracted position in a direction opposite to the first direction under the driving force applied by the elastic member 150. When the needle carrier 140 reaches the retracted position, the needle body 1402 can be arranged such that its front end is completely contained within the first movement space 1111, thereby keeping the needle body 1402 from being exposed or protruding outside the applicator 10.

[0181] Exemplary embodiments regarding the operation of the bridging component

[0182] Figure 40 This is a partial cross-sectional view showing an exemplary embodiment of the state of the bridging member 1330 before its breakage during operation of the applicator assembly 1, and Figure 41 This is a partial cross-sectional view of an exemplary embodiment showing the state of the bridging member 1330 breaking during operation of the applicator assembly 1.

[0183] Figure 40This diagram illustrates the positional relationship between the bridging member 1330 and the bridging member pressure application part 1116 when the sensor unit carrier 130 is in its initial position, but may include, but is not limited to, the following: Figure 40 The case shown is that the bridging member 1330 is arranged at a certain distance from the bridging member pressure part 1116 at the initial position. It can also include the case where the front end of the bridging member pressure part 1116 is kept in abutting against the bridging member 1330 at the initial position.

[0184] When the handle housing 120 is pressed and moved by the user in the first direction, the sensor unit carrier 130 also moves along the first direction together with the handle housing 120. Figure 37 As shown, the bridge 1330 can only break when a force greater than the designed breaking strength of the bridge 1330 during manufacturing is applied to the handle housing 120, and only when the bridge 1330 breaks can the percutaneous sensor component 330 be properly triggered and inserted subcutaneously. Furthermore, Figure 37 The example shown illustrates a case where the bridging member 1330 breaks at the weak point 1332, but it may also include a case where the bridging member 1330 breaks in a region other than the weak point 1332.

[0185] Exemplary embodiments regarding the interaction between the first movement restriction part and the second movement restriction part

[0186] Figure 42 These are cross-sectional views and partially enlarged cross-sectional views illustrating an exemplary embodiment of the positional relationship between the first movement restriction part 1220 and the second movement restriction part 1150 in the state before operation of the applicator assembly 1. Figure 43 (a) to (c) are enlarged cross-sectional views showing, in turn, exemplary embodiments illustrating the positional relationship between the first movement restriction 1220 and the second movement restriction 1150 during operation of the applicator assembly 1.

[0187] like Figure 42 and Figure 43 As shown in (a), in the state before the application assembly 1 is operated, the support surface 1222 of the first movement limiting part 1220 and the first support surface 1153b of the first movement limiting locking member 1152 can be arranged to face each other. Therefore, even if a force is applied to the handle housing 120 in the opposite direction 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 locking member 1152 will abut and support each other, so the handle housing 120 can no longer move in the opposite direction to the first direction, thereby effectively preventing the handle housing 120 from arbitrarily detaching from the main body housing 110.

[0188] In addition, such as Figure 43As shown in (b) and (c), during the triggering of the applicator assembly 1, the inclined surface 1221 of the first movement limiting part 1220 moves to a position adjacent to the second inclined surface 1155a of the second movement limiting lock member 1154. Thereafter, with the inclined surface 1221 of the first movement limiting part 1220 abutting against the second inclined surface 1155a of the second movement limiting lock member 1154, the handle housing 120 moves in the first direction, and the other end of the movement limiting body 1151 twists and deforms toward the second internal space 1102, causing the first movement limiting part 1220 to pass through the second movement limiting lock member 1154. After the first movement limiting part 1220 passes through the second movement limiting lock member 1154, the movement limiting body 1151 returns to its state before the twisting deformation, and the support surface 1222 of the first movement limiting part 1220 and the second support surface 1155b of the second movement limiting lock member 1154 are facing each other. Through the interaction between the support surface 1222 of the first movement limiting part 1220 and the second support surface 1155b of the second movement limiting locking member 1154, the movement of the handle housing 120 in the direction opposite to the first direction is restricted, thus strictly limiting the re-use of the applicator 10 after the transdermal sensor member 330 is triggered.

[0189] Exemplary embodiments regarding the function of the clamp arm protrusion

[0190] Figures 44 to 46 This is a cross-sectional view showing an exemplary embodiment of applying and releasing pressure to the clamping arm protrusion 1424 during operation of the applicator assembly 1.

[0191] Figure 44 This diagram shows the state of the applicator assembly 1 before operation, where the clamping arm protrusion 1424 is arranged without passing over the first stepped ramp 1123. That is, the clamping arm protrusion 1424 remains unpressed by the stepped portion 1121, so the clamping arm 1422 can slightly loosely clamp the sensor unit 30. Furthermore, with... Figure 44 In contrast, before the application assembly 1 is operated, the clamping arm protrusion 1424 can also be arranged in a state passing through the first step slope 1123. In this case, the clamping arm protrusion 1424 is pressed by the step portion 1121, so the clamping arm 1422 can maintain a state of firmly clamping the sensor unit 30.

[0192] When the user presses the handle housing 120 in the first direction, as Figure 45 As shown, the clamping arm protrusion 1424 moves along the first direction while being pressed by the step portion 1121, and during this process, the sensor unit 30 can move toward the transmitting unit 40 while being firmly clamped by the clamping arm 1422.

[0193] Then, as Figure 46 As shown, the clamping arm protrusion 1424 can pass through the second stepped inclined surface 1124, thereby relieving the pressure exerted by the stepped portion 1121 on the clamping arm protrusion 1424, and the clamping arm 1422 can clamp the sensor unit 30 in a slightly relaxed state and transfer the sensor unit 30 to the transmitting unit 40. During the insertion of the percutaneous sensor component 330 subcutaneously, the sensor unit housing 310 continuously transmits a force in the first direction to the sensor unit 30. Therefore, even if the clamping arm 1422 clamps the sensor unit 30 in a slightly relaxed state and transfers the sensor unit 30 to the transmitting unit 40, the sensor unit 30 can be accurately transferred to the mounting slot 412. In addition, by clamping the sensor unit 30 in a slightly relaxed state and transferring the sensor unit 30 to the mounting slot 412 of the transmitting unit 40, the clamping arm 1422 can effectively prevent operational errors caused by the sensor unit 30 being dragged by the needle carrier 140 during the return of the needle carrier 140 to the retracted position.

[0194] Exemplary embodiments regarding the operation of the transmitting unit support.

[0195] Figure 47 and Figure 48 This is a cross-sectional view showing an exemplary embodiment of restricting and releasing the movement restriction of the transmitting unit 40 by the transmitting unit support 1160 during the operation of the applicator assembly 1.

[0196] like Figure 47 As shown, in the state before operation of the applicator assembly 1, the front end of the hook portion 1164 provided on the sending unit support hook 1162 is arranged inside the sending unit housing groove 417 of the sending unit housing 410, thereby effectively preventing the sending unit 40 from arbitrarily detaching from the sending unit receiving portion 1104. In this case, the extension arm pressing portion 1326 provided on the sensor unit carrier 130 can be kept spaced apart from the pressing portion 1165 of the sending unit support hook 1162. Before operation of the applicator assembly 1 or during the insertion of the percutaneous sensor member 330 subcutaneously, the sending unit support hook 1162 can prevent the sending unit 40 from arbitrarily detaching from the sending unit receiving portion 1104, thus effectively improving the economy and operational accuracy of the applicator assembly 1.

[0197] In addition, such as Figure 48As shown, when the applicator assembly 1 is operated to move the sensor unit carrier 130 to the insertion position, the extension arm pressing part 1326 presses against the inclined surface 1165a formed on the pressing part 1165, causing the transmitting unit support hook 1162 to twist and deform in a direction away from the transmitting unit 40. As a result, the front end of the hook part 1164 disengages from the transmitting unit housing groove 417, thereby releasing the movement restriction of the transmitting unit 40 by the transmitting unit support hook 1162. Through the interaction between the transmitting unit support part 1160 and the extension arm pressing part 1326, the movement restriction of the transmitting unit support hook 1162 on the transmitting unit 40 is released during the subcutaneous insertion of the transdermal sensor member 330. Therefore, it can effectively prevent the wearable unit 20 from being dragged by the applicator 10 during the separation of the applicator 10 from the wearable unit 20 after the subcutaneous insertion of the transdermal sensor member 330 is completed.
