Description

Technical Field

[0001] The present invention relates to an applicator and an applicator assembly. Background Art

[0002] Recently, with the development of medical technology, various types of medical devices that can be directly used by users who are not medical staff have been developed and sold. As an example of such a medical device, for example, there may be a blood glucose meter that a user directly uses on themselves in order to directly monitor their own biological information such as blood glucose levels (blood glucose values).

[0003] Blood glucose meters include blood sampling blood glucose meters and continuous glucose monitoring systems (CGMS: Continuous Glucose Monitoring System; or continuous blood glucose meters).

[0004] Blood sampling blood glucose meters require the user's blood sampling behavior as an essential element, making it difficult to immediately monitor hypoglycemic states.

[0005] Although continuous glucose monitoring systems increase the user's trouble during use, they can relatively immediately monitor biological information. From this point, their usage is gradually increasing.

[0006] On the other hand, most applicators of continuous glucose monitoring systems are discarded after one use, thus increasing environmental pollution.

[0059] Referring to Figures 1 to 27 An applicator assembly 10 according to an embodiment of the present invention includes a sensing device 20, an applicator 30, an anti-operation part 40, and a protection piece 50.

[0060] The sensing device 20 can sense biological information at a plurality of different time points while being attached to the user's skin, and wirelessly transmit the sensed data to the external terminal 5. Among them, the biological information can be a blood glucose value, however, the scope of the present invention is not limited thereto. Among them, the so-called plurality of different time points can be, for example, at least 3 or more time points with actually the same period, however, the scope of the present invention is not limited thereto. The external terminal 5 can be various, for example, it can be a device such as the user's portable terminal, a dedicated medical device, a PC, a server, etc. that can receive the sensed data of the sensing device 20.

[0061] The sensing device 20 includes a sensor unit 100 and a base unit 200. The sensing device 20 can be provided to the user in a form in which the sensor unit 100 and the base unit 200 are separated from each other in the applicator 30 described below. As the user operates the applicator 30, the sensor unit 100 and the base unit 200 of the sensing device 20 can be combined. The sensing device 20 can be detached from the applicator 30 and attached to the user's body. In this specification, the sensing device 20 is used to include all meanings of the state in which the sensor unit 100 and the base unit 200 are separated from each other and the state in which the sensor unit 100 and the base unit 200 are combined with each other.

[0062] On the other hand, in this specification, it is described on the premise that the sensing device 20 includes a sensor unit 100 and a base unit 200, wherein the sensor unit 100 and the base unit 200 are arranged separately in the applicator 30 and are combined with each other by the user's operation on the applicator 30. However, this description does not exclude other forms of sensing devices from the scope of the present invention. As another non-limiting example, the sensor unit 100 and the base unit 200 can also be arranged in a combined form in the applicator 30, and while maintaining the combined state, they can move in the first direction (refer to Figure 19 , Figure 20 , Figures 23 to 27 the direction shown) by the user's operation on the applicator 30 to attach to the user's skin, and while maintaining the combined state, they can be detached from the applicator 30.

[0063] At least a part of the sensor unit 100 can be inserted into the user's skin to sense biological information and generate a signal. The sensor unit 100 includes a sensor 110, a sensor unit housing 120, a sensor adhesion part 149, and an adhesion pad 152.

[0064] At least a part of the sensor 110 can be inserted into the user's skin to sense biological information. The sensor 110 includes a sensor body 111, a connection part 112, an intermediate part 113, an extension part 114, and an insertion part 116.

[0065] The sensor body 111 can be disposed inside the sensor unit housing 120 described later. The connection part 112 can extend from one side of the sensor body 111 to connect the sensor body 111 and the intermediate part 113. The connection part 112 can place the sensor body 111 and the intermediate part 113 on different planes. The intermediate part 113 can extend from one side of the connection part 112 to connect the connection part 112 and the insertion part 116. The intermediate part 113 can include an extension part 114 protruding from the connection part 112 in one direction. The insertion part 116 can be connected to the extension part 114 and inserted into the user's skin. The insertion part 116 can be formed in a relatively slender probe shape so as to be smoothly inserted into the user's skin.

[0066] As an example, after the sensor body 111, the connection part 112, the intermediate part 113, and the insertion part 116 are made into a flat plate shape, the connection part 112 will be bent and deformed. Due to the bending deformation of the connection part 112, the intermediate part 113 and the insertion part 116 can be disposed on a plane different from the sensor body 111, however, the scope of the present invention is not limited thereto.

[0067] On the other hand, in Figure 5 and Figure 6 , it is shown that the intermediate part 113 and the insertion part 116 are disposed on the same plane, and the intermediate part 113 is vertically disposed with respect to the sensor body 111. However, the angle between the intermediate part 113 and the sensor body 111, or the angle between the insertion part 116 and the sensor body 111 can be changed diversely.

[0068] On the other hand, conductive traces electrically connected to the electrodes of the sensor body 111 can be disposed in the connection part 112, the intermediate part 113, and the insertion part 116.

[0069] The sensor unit housing 120 houses at least a part of the sensor 110 inside. As an example, the sensor body 111, the connection part 112, and the intermediate part 113 of the sensor 110 can be disposed inside the sensor unit housing 120, and at least a part of the insertion part 116 of the sensor 110 can protrude from the sensor unit housing 120. The sensor unit housing 120 includes a housing base 121 and a housing cover 134.

[0070] The housing base 121 includes a base portion 122 that supports the sensor main body 111 and a boss 127 that protrudes from the surface of the base portion 122. A through hole 124 may be formed on one side of the base portion 122. A later-described electrical contact portion 225 may be inserted into the through hole 124. A housing base hole 128 may be formed on the boss 127. An insertion portion 116 and a later-described needle 485 may be inserted into the housing base hole 128. A pawl protrusion 125 may be formed on the edge of the base portion 122. When the housing base 121 is combined with a later-described housing cover 134, the pawl protrusion 125 may be inserted into a pawl groove 139 of the housing cover 134.

[0071] The housing cover 134 may be combined with the housing base 121 to cover the sensor main body 111. A housing cover hole 135 may be formed on one side of the housing cover 134. The housing cover hole 135 is connected to the housing base hole 128 of the housing base 121. Accordingly, the needle 485 may protrude to the outside of the sensor unit housing 120 through the housing cover hole 135 and the housing base hole 128. A pawl groove 139 may be formed on the housing cover 134. When the housing base 121 is combined with the housing cover 134, the pawl protrusion 125 of the housing base 121 may be inserted into the pawl groove 139. A sensor unit groove 138 may be formed on the housing cover 134. In the sensor unit groove 138, a pressing protrusion 442 of a reciprocating member 431 may be inserted. A sensor unit groove 138 is formed to protrude from the inner surface of the housing cover 134 facing the housing base 121. The area where the sensor unit groove 138 protrudes from the inner surface of the housing cover 134 may be inserted into a housing engagement portion of the housing base 121. A holding protrusion 136 may be formed on the inner surface of the housing cover 134 facing the housing base 121. The end of the holding protrusion 136 is disposed facing the intermediate portion 113 inserted into the housing base hole 128, and the movement of the intermediate portion 113 of the sensor 110 may be restricted. Due to such a holding protrusion 136, the insertion portion 116 of the sensor 110 may be stably held in a state of protruding a predetermined length from the sensor unit housing 120. In addition, due to the holding protrusion 136, the insertion portion 116 of the sensor 110 may be held at a predetermined depth inserted into the user's skin without retreating from the user's skin in a state of being inserted into the user's skin.

[0072] The sensor adhesion portion 149 may be disposed between the housing base 121 and the sensor main body 111 to attach the sensor main body 111 to the housing base 121. The sensor adhesion portion 149 may be formed in the form of a double-sided tape having adhesiveness on both sides, however, the scope of the present invention is not limited thereto. A sensor adhesion portion opening 150 may be formed in the central portion of the sensor adhesion portion 149. A later-described electrical contact portion 225 may be inserted into the sensor adhesion portion opening 150.

[0073] The adhesive pad 152 can be disposed between the outer housing 134 and the sensor body 111 to attach the sensor body 111 to the outer housing 134. The adhesive pad 152 can be formed in the form of a double-sided tape having adhesiveness on both sides, however, the scope of the present invention is not limited thereto. An adhesive pad engaging portion can be formed on the adhesive pad 152. Through the adhesive pad engaging portion, the sensor unit groove 138 protruding from the inner surface of the outer housing 134 can be inserted into the housing engaging portion of the housing base 121.

[0074] The base unit 200 can be combined with the sensing unit 100 to be attached to the user's skin. The base unit 200 can be electrically connected to the sensor unit 100 to process the biological information measured by the sensor unit 100 and send it to the external terminal 5. The base unit 200 includes a base unit housing 210, electronic components, an adhesive layer 230, a protective sheet 240, and an adhesive portion 250.

[0075] The base unit housing 210 can be combined with the sensor unit housing 120. The base unit housing 210 can form the overall appearance of the base unit 200. An insertion hole 211 can be formed in the base unit housing 210. The insertion hole 211 is formed in a shape that allows the boss 127 of the sensor unit 100 to be inserted, and at least a part of the insertion portion 116 of the sensor 110 can be inserted into the insertion hole 211. On the base unit housing 210, an installation portion 212 that is an area for accommodating the sensor unit housing 120 can be formed. The installation portion 212 includes a base unit groove 213. The sensor unit housing 120 can be combined with the base unit groove 213. An outer housing groove 217 can be formed in the base unit housing 210. At least a part of the locking hook 360 of the applicator 30 described later can be inserted into the outer housing groove 217. An electrical contact portion 225 can be formed in the base unit housing 210. When the sensor unit 100 is combined with the base unit 200, the electrical contact portion 225 can contact the sensor body 111 through the through hole 124 and the sensor adhesive portion opening 150 of the sensor unit 100. The electrical contact portion 225 is formed in a shape that can be elastically deformed to stably contact the sensor body 111. The electrical contact portion 225 can be electrically connected to the substrate 223 described later.

[0076] The electronic components are disposed inside the base unit housing 210. The electronic components can include a substrate 223, an electrical contact portion 225 that contacts the sensor 110, a battery 228, and various chips. The chips can be disposed on the substrate 223. The chips can include a processor chip for processing signals and a communication chip for communicating with the external terminal 5.

[0077] As a modification example, the base unit 200 may not include at least a part of the electronic components. As an example, the base unit 200 may be composed only of a structure simply for attaching the sensor unit 100 to the user's skin. At this time, another electronic unit may be attached to and detachably coupled to the base unit 200. Such an electronic unit may include a processor chip that processes the biological information sensed by the sensor unit 100 and a communication chip that transmits the processed sensed data to the external terminal 5. In addition, the electronic unit may be electrically connected to the sensor unit 100 after the sensor unit 100 is coupled to the base unit 200.

[0078] The adhesive layer 230 may be disposed on one surface of the base unit housing 210 to couple the sensor unit housing 120 and the base unit housing 210. The adhesive layer 230 may seal between the sensor unit housing 120 and the base unit housing 210 so that moisture or foreign substances cannot flow into the side of the electrical contact portion 225. Adhesive layer holes 231 and 232 may be formed in the adhesive layer 230. The adhesive layer hole 231 is connected to the insertion hole 211, and thus the adhesive layer hole 231 allows the needle 485 and the insertion portion 116 of the sensor 110 to pass through. The electrical contact portion 225 may pass through the adhesive layer hole 232. The adhesive layer 230 may be formed in the form of a double-sided tape having adhesiveness on both sides.

[0079] The protective sheet 240 may cover the adhesive layer 230 to prevent the adhesiveness of the adhesive layer 230 from decreasing. The protective sheet 240 includes a material with a peeling property and can be easily removed from the adhesive layer 230 to expose the adhesive layer 230 before the sensor unit 100 and the base unit 200 are coupled. The protective sheet 240 may include a protective portion 241 that covers the adhesive layer 230 and a wing portion 242 that extends from the protective portion 241. A protective sheet opening 244 may be formed in the protective portion 241. The protective sheet opening 244 may be connected to the adhesive layer hole 232 of the adhesive layer 230. A protective sheet hole 245 may be formed in the wing portion 242. Since the wing portion 242 protrudes from the base unit housing 210, the wing portion 242 and the protective sheet hole 245 may be coupled to a moving tongue 600 of a dispenser 30 described later.

[0080] The base unit 200 is coupled to the dispenser 30 in a state where the protective sheet 240 is attached to the adhesive layer 230. The protective sheet 240 may be detached from the adhesive layer 230 by means of a moving tongue 600 described later before the sensor unit 100 and the base unit 200 are coupled. By the user operating the moving tongue 600, the protective sheet 240 is detached from the adhesive layer 230. Then, by the user operating the dispenser 30 described later, the sensor unit 100 may move in the first direction (refer to Figure 19 、 Figure 20 、 Figures 23 to 27 the direction shown) and be coupled to the base unit 200.

[0081] The adhesion part 250 can be disposed on one side of the base unit housing 210 so that the base unit housing 210 adheres to the user's skin. An adhesion part opening through which the insertion part 116 of the sensor 110 and the needle 485 can pass is formed in the central part of the adhesion part 250.

[0082] The applicator 30 forms the overall appearance of the applicator assembly 10 of the present embodiment. The applicator 30 can cover at least a part of each of the sensor unit 100 and the base unit 200. The applicator 30 can combine the sensor unit 100 and the base unit 200 with each other to form the sensing device 20. The applicator 30 can be detached from the sensing device 20 after the sensor unit 100 and the base unit 200 are combined to form the sensing device 20. The applicator 30 can include an applicator body 300, an insertion unit assembly 400, and an operation part 500.

[0083] The applicator body 300 can form the overall appearance of the applicator 30. The applicator body 300 covers at least a part of each of the sensor unit 100 and the base unit 200 before the user operates the applicator 30. The applicator body 300 includes bodies 310, 330, a locking hook 360, a top shell 370, and a top shell restraint member 380.

[0084] The bodies 310, 330 accommodate at least a part of the insertion unit assembly 400 described later and support the insertion unit assembly 400. Hereinafter, for the sake of convenience of description, it is assumed that the bodies 310, 330 include a bottom frame 310 and an intermediate frame 330 that are independently formed and combined with each other. However, such a description does not exclude the bodies formed in an integrated manner from the scope of the present invention.

[0085] The bottom frame 310 can abut against the user's skin when the user uses the applicator assembly 10 of the present embodiment. Specifically, in the user's usage environment described above, the bottom 312 of the bottom frame 310 can abut against the user's skin. A groove 313 may be formed in the bottom 312. At least a part of the base unit 200 is received in the groove 313 so that the base unit 200 is detachably coupled to the bottom frame 310. A bottom frame opening 314 may be formed in the central portion of the bottom frame 310. A fence portion 316 may be disposed on the outer periphery of the bottom frame opening 314. At least a part of the insertion unit assembly 400 described later is inserted into the bottom frame opening 314, and the fence portion 316 can support the insertion unit assembly 400. Accordingly, the bottom frame 310 can support the insertion unit assembly 400. Support portions 318 may be disposed on both sides of the bottom frame opening 314. The support portions 318 can rotatably support the hook 360 described later. The support portion 318 includes an elastically deformable elastic bracket 319 and a support protrusion 320 protruding from the surface of the elastic bracket 319. The support protrusion 320 presses against the hook 360 to prevent the hook 360 from separating from between the elastic bracket 319 and the fence portion 316. A platform 320 may be formed inside the bottom frame 310. The platform 320 can support the moving tongue 600 so that the moving tongue 600 described later can linearly move stably. An entrance / exit 322 may be formed in the bottom frame 310. The entrance / exit 322 is formed on one side of the outer surface of the bottom frame 310. The moving tongue 600 disposed on the platform 320 can enter and exit the outside of the bottom frame 310 through the entrance / exit 322. An applicator body engaging portion 324 may be formed on the bottom frame 310. The applicator body engaging portion 324 includes an engaging protrusion 325 formed inside the bottom frame 310 so as to be engageable with the moving tongue 600.

[0086] Support portions 318 for coupling the hook 360 may be formed on the bottom frame 310. The support portion 318 includes an elastically deformable elastic bracket 318-1 and a support protrusion 318-2 protruding from the surface of the elastic bracket 319. The support protrusion 318-2 presses against the hook 360 described later to prevent the hook 360 from separating from between the elastic bracket 318-1 and the fence portion 316. Additionally, a holding protrusion 327 that is elastically deformable to restrict the movement of the hook 360 may be formed on the bottom frame 310. The support portion 318 and the holding protrusion 327 will be described later.

[0087] An outer fence 328 is formed on the bottom frame 310. The outer fence 328 includes: a first outer fence 328-1 having a relatively maximum diameter and a relatively minimum height; a second outer fence 328-2 having a diameter smaller than that of the first outer fence 328-1 and a height higher than that of the first outer fence 328-1; and a third outer fence 328-3 having a diameter smaller than that of the second outer fence 328-2 and a height higher than that of the second outer fence 328-2. An intermediate frame 330 and an operation unit 500 described below are disposed in the internal space formed by the third outer fence 328-3. A skirt 372 of a top case 370 described below is placed on the upper surface of the second outer fence 328-2. If the top case 370 is placed on the upper surface of the second outer fence 328-2, the third outer fence 328-3 is covered by the top case 370 and does not expose to the outside. A top case restraint member 380 is placed on the upper surface of the first outer fence 328-1. A coupling groove 328-1R is formed on the upper surface of the first outer fence 328-1 for inserting a first coupling protrusion 381 of the top case restraint member 380. A coupling groove 328-2R is formed at the lower part of the second outer fence 328-2 for inserting a second coupling protrusion 382 of the top case restraint member 380. The coupling protrusions 381, 382 of the top case restraint member 380 are coupled to the coupling grooves 328-1R, 328-2R of the bottom frame 310, so that the top case restraint member 380 can be fixed to the bottom frame 310. As a result, the top case 370 placed on the upper surface of the second outer fence 328-2 of the bottom frame 310 can be restrained by the bottom frame 310.

[0088] The intermediate frame 330 is disposed on the bottom frame 310 and supports an insertion unit assembly 400 described below. The insertion unit assembly 400 is inserted into the intermediate frame 300. The intermediate frame 330 includes a platform 331 for supporting an operation unit 500 described below. An intermediate frame opening 332 connected to a bottom frame opening 314 of the bottom frame 310 may be formed at the central part of the platform 331. At least a part of the insertion unit assembly 400 described below can be inserted into the bottom frame opening 314 through the intermediate frame opening 332.

[0089] Guide protrusions 334 may be disposed on the intermediate frame 330. Specifically, the guide protrusions 334 may be disposed on both sides of the platform 331 of the intermediate frame 330. The guide protrusions 334 can guide the operation unit 500 along a third direction (refer to Figure 19 , Figure 20 , Figures 23 to 27 shown direction) perpendicular to the first direction (refer to Figure 19 , Figure 20 , Figures 23 to 27Movement in the indicated direction). That is, the guiding protrusion 334 can guide the operation unit 500 to move from the deactivated position to the activated position. Among them, the deactivated position can mean that the operation unit 500 does not allow the sensor unit 100 and the insertion unit 430 to move in the first direction (refer to Figure 19 , Figure 20 , Figures 23 to 27 the indicated direction). The activated position can mean that the operation unit 500 allows the sensor unit 100 and the insertion unit 430 to move in the first direction (refer to Figure 19 , Figure 20 , Figures 23 to 27 the indicated direction).

[0090] A locking unit 338 can be formed on the intermediate frame 330. The locking unit 338 can prevent the operation unit 500 from moving in the third direction, that is, it can prevent the operation unit 500 from moving from the deactivated position to the activated position. The locking unit 338 can be disposed in a through hole 336 formed on the platform 331. The locking unit 338 includes a locking body 339 connected to the intermediate frame 330 so as to be engaged with or disengaged from the operation unit 500. The locking body 339 includes: a main body portion 340, the main body portion 340 being elastically deformably connected to the intermediate frame 330; a hook portion 341, the hook portion 341 being connected to one side of the main body portion 340 in a manner capable of engaging with the operation unit 500; and a support leg portion 342, the support leg portion 342 being connected to the other side of the main body portion 340 in a manner capable of abutting against the moving tongue 600. When the support leg portion 342 abuts against the moving tongue 600, the hook portion 341 can be deflected in the direction of engaging with the operation unit 500. When the support leg portion 342 disengages from the moving tongue 600, the hook portion 341 can be deflected in the direction of disengaging from the operation unit 500.

[0091] An elastic pressing portion 345 can be disposed on the intermediate frame 330. The elastic pressing portion 345 can elastically support the operation unit 500. The elastic pressing portion 345 can abut against the operation unit 500 to elastically support the operation unit 500, such that the operation unit 500 cannot easily move from the deactivated position to the activated position. That is, the elastic pressing portion 345 generates a resistance force against the force applied by the user to push the operation unit 500. Therefore, the elastic pressing portion 345 enables the operation unit 500 to move in the third direction only when the user applies a force above a certain level to the operation unit 500.

[0092] The intermediate frame 330 further includes a button guide 346 extending upward from the platform 331. A guide hole 347 is formed in the button guide 346. If the operation unit 500 described later is coupled to the intermediate frame 330, the button unit 510 of the operation unit 500 is disposed within the guide hole 347 of the intermediate frame 330. On the other hand, when the top case 370 is fixed to the bottom frame 310 by using the top case restraint member 380 described later, at least a portion of the button guide 346 of the intermediate frame 330 is exposed to the outside together with the button unit 510 of the operation unit 500 through the opening 371 of the top case 370.

[0093] The locking hook 360 can be coupled to the bottom frame 310. The locking hook 360 can maintain the coupled state of the base unit 200 and the bottom frame 310 by engaging with the base unit 200 accommodated in the groove 313. The locking hook 360 can be disengaged from the base unit 200 after the sensing device 20 is attached to the user's skin.

[0094] The locking hook 360 is pivotally coupled to the support portion 318 of the bottom frame 310. The locking hook 360 includes a pivot portion 361 rotatably coupled to the support portion 318, a hook portion 362 protruding from one side of the pivot portion 361, an extension portion 363 protruding from the other side of the pivot portion 361, and an extension portion 364 protruding from the end of the pivot portion 361.

[0095] The pivot portion 361 is rotatably disposed between the elastic bracket 318-1 and the fence portion 316. The support protrusion 318-2 of the support portion 318 abuts against the upper side of the pivot portion 361 to prevent the pivot portion 361 from separating from between the elastic bracket 318-1 and the fence portion 316. In addition, the pivot portion 361 can slide along its length direction while being supported by the support portion 318.

[0096] The hook portion 362 can protrude from one side of the pivot portion 361, and its end can be inserted into the housing groove 217 of the base unit 200. When the end of the hook portion 362 is inserted into the housing groove 217 of the base unit 200, the movement of the extension portion 363 is restricted by the operation unit 500. Therefore, the locking hook 360 is restricted from moving by the operation unit 500, and thus the coupled state of the base unit 200 and the bottom frame 310, that is, the coupled state of the base unit 200 and the applicator body 300, can be maintained. On the other hand, if the sensor unit 100 moves in the first direction and is coupled to the base unit 200, the restriction of the extension portion 363 by the operation unit 500 is released. Therefore, the end of the hook portion 362 can be disengaged from the housing groove 217 of the base unit 200.

[0097] The extension part 364 protrudes from the end of the pivot part 361. The extension parts 364 are respectively arranged at both ends of the pivot part 361. The extension part 364 has a diameter larger than that of the pivot part 361. The extension part 362 can contact the elastic bracket 319 to restrict the movement of the pivot part 361 and limit the moving distance of the pivot part 361 in the length direction.

[0098] The locking hook 360 can move along the third direction by means of the limit part protrusion 535 of the operation part 500. The locking hook 360 moving along the third direction cannot move along the fourth direction due to the holding protrusion 327.

[0099] In this embodiment, the limit part protrusion 535 of the limit part 520 is arranged such that it contacts the locking hook 360 only when the operation part 500 moves along the third direction, and when the operation part 500 that has completed the movement along the third direction moves along the fourth direction, it disengages from the locking hook 360. The limit part protrusion 535 includes a limit part protrusion contact part 536 and a limit part protrusion pawl 537. The limit part protrusion contact part 536 can abut against the upper surface of the extension part 363 of the locking hook 360 to restrict the tilting movement of the locking hook 360. The limit part protrusion pawl 537 can abut against one side part of the extension part 363 to push the locking hook 360 to release the fixed mode of the locking hook 360.

[0100] As Figure 14 shown in (a) of Figure 21 As shown in (a) of Figure 14 when the operation part 500 is in the deactivated position, the limit part protrusion contact part 536 abuts against the locking hook 360, thereby restricting the tilting movement of the locking hook 360. At this time, the locking hook 360 can engage with the base unit 200 to maintain the connection relationship between the base unit 200 and the applicator main body 300. At this time, as

[0101] As Figure 14 shown in (b) of Figure 21 If the operation part 500 moves along the third direction by means of the operation of the user as shown in (b) of

[0102] Refer to Figure 14In (c) thereof, if the pressure applied by the user to the operation unit 500 in the third direction is removed, the limiting part protrusion 535 disengages from the locking hook 360. Specifically, if the pressure applied by the user to the operation unit 500 in the third direction is removed, the operation unit 500 moves in the fourth direction, while the locking hook 360 cannot move in the fourth direction due to the holding protrusion 327. Therefore, the limiting part protrusion 535 disengages from the locking hook 360. In this embodiment, the operation unit 500 can move in the fourth direction and return to the initial deactivated position. As Figure 14 As shown in (c) thereof, when the operation unit 500 is in the initial deactivated position, the limiting part protrusion 535 disengages from the locking hook 360. Therefore, the locking hook 360 can tilt and the base unit 200 can be detached from the applicator main body 300.

[0103] The top shell 370 is coupled to the main bodies 310 and 330 to cover the insertion unit assembly 400 and the operation unit 500 described later. Specifically, the top shell 370 is placed on the bottom frame 310 and fixed to the bottom frame 310 by a top shell restraining member 380 described later. Thereby, the top shell 370 can cover at least a part of the bottom frame 310, the intermediate frame 330, the insertion unit assembly 400, and the operation unit 500. On the top shell 370, there is provided a top shell opening 371 through which the button part 510 of the operation unit 500 described later is exposed to the outside. At the lower end of the top shell 370, a flange 372 extending in the outer diameter direction is formed. The flange 372 is placed on the upper surface of the second outer fence 328-2 of the bottom frame 310.

[0104] At least a part of the applicator main body 300 is formed of molded pulp. Molded pulp can be manufactured by injecting a pulp solution obtained by decomposing waste paper or pure pulp with water into a mold, and then drying after vacuum suction molding. Molded pulp can replace the synthetic resin conventionally used as the material of the applicator main body, and can minimize environmental hazards. For example, at least one of the bottom frame 310, the intermediate frame 330, and the top shell 370 of the applicator main body 300 can be formed of molded pulp. Hereinafter, for the sake of convenience of description, it is described on the premise that at least a part of the top shell 370 is formed of molded pulp, however, the scope of the present invention is not limited thereto.

[0105] At least a part of the top shell 370 is formed of molded pulp. For example, a part of the area of the top shell 370 can be formed of molded pulp, and the remaining area can be formed of a material other than molded pulp. Among them, the part of the area and the remaining area can be combined with each other by physical, mechanical, and chemical methods. As another example, the top shell 370 can be a single piece formed of molded pulp. In the former case, the materials of the respective areas of the top shell 370 can be different. In the latter case, the top shell 370 can be formed in a relatively simple manner. On the inner surface of the top shell 370, no structure for the combination between the top shell 370 and the bottom frame 310 needs to be formed.

[0106] The pulp molding may include pulp fibers and a filler.

[0107] The pulp fibers may include one or more fibers selected from the group consisting of wood pulp fibers and non-wood pulp fibers according to the raw materials from which the fibers are obtained. The wood pulp fibers may include fibers obtained from softwood pulp (SwP), hardwood pulp (HwP), or a mixture of both. The non-wood pulp fibers may include fibers obtained from straw pulp, bagasse pulp, reed pulp, bamboo pulp, bast fiber pulp, cloth pulp, cotton pulp, or a mixture thereof. The pulp fibers may be based on the processing method of the raw materials, for example, using pulp formed by mechanically and / or chemically treating wood or other fiber plants as the raw material. For example, the pulp fibers may include fibers obtained from mechanical pulp, chemical pulp, recycled pulp, and mixtures thereof, where mechanical pulp includes groundwood pulp (GP), refiner pulp (RP), thermo-mechanical pulp (TMP), etc., obtained by mechanically pulverizing wood or other plants; chemical pulp includes kraft pulp (KP), sulphite pulp (SP), semi-chemical pulp (SCP), etc., obtained by treating wood or other plants with various chemicals to remove non-fibrous substances; recycled pulp includes waste paper pulp, deinking pulp (DIP), etc., made from waste paper.

[0108] Non-limiting examples of the filler may include at least one of a reinforcing material for enhancing the rigidity of the pulp molding, a moisture-proof material for improving the moisture resistance of the pulp molding, and a fireproof material for improving the thermal stability of the pulp molding. As an example of the filler, it may be in the form of short fibers or long fibers, or in the form of particles having at least one of a spherical shape and a needle shape, however, the scope of the present invention is not limited thereto. At this time, the short fibers may mean fibers having a fiber length of 500 μm to 3 mm, however, it is not limited thereto. In addition, the short fibers may have a fineness of 0.5 to 10 denier, for example, 0.5 to 6 denier per unit fiber length, however, it is not limited thereto. In addition, the powder particle size (D50) may be 3 μm to 3 mm, however, it is not limited thereto. The filler may be dispersed between the pulp fibers, for example, and distinguished from the pulp fibers. Alternatively, the filler may be integrated with the pulp fibers without being distinguished from the pulp fibers. Or, the filler may be provided in the form of fibers and form a composite fiber structure together with the pulp fibers. The filler may include, for example, petroleum-based polymers and / or biodegradable polymers. The petroleum-based polymers may be polyolefin polymers such as polyethylene terephthalate (PET), high density polyethylene (HDPE), etc., polyvinyl alcohol (PVA), and their blends or copolymers between monomers. The biodegradable polymer refers to a polymer that decomposes into low molecular compounds in the presence of microorganisms in nature. For example, it may be one or more selected from polylactic acid (PLA), thermoplastic starch (TPS), aliphatic polyester (AP), polycaprolactone (PCL), polyglycolic acid (PGA), polybutylene succinate (PBS), polybutylene adipate terephthalate (PBAT), polyhydroxy alkanoate (PHA), and their mixtures, however, it is not limited thereto. In addition, the biodegradable polymer may also be a bio-based polymer and biodegradable. The so-called bio-based polymer and biodegradable may be one or more selected from bio-polyethylene (Bio-PE), bio-polyethylene terephthalate (Bio-PET), bio-polytrimethylene terephthalate (Bio-PTT), bio-polyamide (Bio-PA), bio-polypropylene (Bio-PP), and their mixtures, however, it is not limited thereto.

[0109] The top shell restraint member 380 is coupled to the bottom frame 310, such that the top shell 370 disposed on the bottom frame 310 is restrained by the bottom frame 310. The top shell restraint member 380 may be formed in an annular shape that generally surrounds the lower outer periphery of the top shell 370. The top shell restraint member 380 is disposed on top of the first outer fence 328-1 of the bottom frame 310 and is coupled to the bottom frame 310. Engagement protrusions 381, 382 for engagement with the bottom frame 310 are formed on the top shell restraint member 380. The first engagement protrusion 381 protrudes from the lower surface of the top shell restraint member 380 facing the upper surface of the first outer fence 328-1. The first engagement protrusion 381 is inserted into an engagement groove 328-1R formed on the upper surface of the first outer fence 328-1. The second engagement protrusion 382 protrudes from the inner surface of the top shell restraint member 380 facing the outer side surface of the second outer fence 328-2. The second engagement protrusion 382 is inserted into an engagement groove 328-2R formed on the outer side surface of the second outer fence 328-2. On the other hand, a pressing protrusion 383 may be formed in the upper region of the inner surface of the top shell restraint member 380. When the top shell restraint member 380 is coupled to the bottom frame 310, the pressing protrusion 383 may press the top shell 370 disposed on the upper surface of the second outer fence 328-2 of the bottom frame 310. On the other hand, the inner diameter of the top shell restraint member 380 may be smaller in the upper part than in the lower part, however, the scope of the present invention is not limited thereto.

[0110] The insertion unit assembly 400 moves the needle 485 in a first direction and a second direction opposite to the first direction, respectively. The needle 485 moves in the first direction in a state of being coupled to the sensor unit 100, and thus the insertion unit assembly 400 moves the sensor unit 100, which is a structure of the sensing device 20, in the first direction. The insertion unit assembly 400 includes a column member 410 and an insertion unit 430. The insertion unit 430 includes a reciprocating member 431, a reciprocating member driver 450, a needle assembly 460, and a release driver 490.

[0111] The column member 410 is fixed to the applicator body 300 and supports the insertion unit 430. The column member 410 includes a column member body 411, and the column member body 411 has a column member opening 412 that opens outward at one end. A space for accommodating the insertion unit 430 is provided in the column member body 411. A release portion 414 is disposed on the inner surface of the column member body 411. The release portion 414 may come into contact with the carrier 462 during the movement of the carrier 462 of the needle assembly 460 described later in the first direction. The carrier 462 abuts against the release portion 414, so that the carrier 462 can be disengaged from the reciprocating member 431 and move relative to the reciprocating member 431.

[0112] On both sides of the column member body 411, there are arranged a clamping portion 416 and a blocking portion 420 for restricting the movement of the reciprocating member 431. The clamping portion 416 has a clamping portion pawl 417 that can engage with one side of the reciprocating member 431. The insertion unit assembly 400 can be coupled to the applicator body 300 in a state where the reciprocating member 431 is temporarily fixed to the column member 410 by the clamping portion 416. When the clamping portion pawl 417 of the clamping portion 416 engages with the reciprocating member tongue 438 of the reciprocating member 431, the reciprocating member 431 is in a state of being temporarily fixed to the column member 410. If the reciprocating member 431 is temporarily fixed to the column member 410 by the clamping portion 416, the problem of accidental movement of the reciprocating member 431 during the assembly process of the insertion unit assembly 400 can be prevented. During the manufacturing process of the applicator assembly 10, after the insertion unit assembly 400 is coupled to the applicator body 300, the clamping portion 416 can be disengaged from the reciprocating member 431. As Figure 9 shown, the applicator assembly 10 can be provided to the user in a state where the clamping portion 416 is disengaged from the reciprocating member 431. The blocking portion 420 can be used to fix the reciprocating member 431 that has completed its movement in the first direction at a corresponding position. The blocking portion 420 has a blocking portion pawl 421 that engages with one side of the reciprocating member 431. After the reciprocating member 431 has completed its movement in the first direction, the blocking portion 420 engages with the pawl portion 439 of the reciprocating member 431 through the blocking portion pawl 421, thereby preventing the reciprocating member 431 from moving in the second direction opposite to the first direction. The blocking portion 420 restricts the movement of the reciprocating member 431, thereby preventing problems with the reuse of the reciprocating member 431 and the applicator 30.

[0113] The reciprocating member 431 is disposed inside the column member 410. The reciprocating member 431 is arranged in such a manner that it can linearly move relative to the column member 410. The reciprocating member 431 includes a reciprocating member main body 432. Inside the reciprocating member main body 432, a space for accommodating a needle assembly 460 described later is provided. A reciprocating projection 434 is disposed on one side of the reciprocating member main body 432. The reciprocating projection 434 protrudes from the reciprocating member main body 432 so as to be able to abut against the operation portion 500. The reciprocating projection 434 and the operation portion 500 described later prevent or allow the reciprocating member 431 to move in the first direction. Specifically, when the reciprocating projection 434 abuts against the operation portion 500, the movement of the reciprocating member 431 in the first direction is prevented. When the reciprocating projection 434 does not abut against the operation portion 500, the reciprocating member 431 is allowed to move in the first direction. Inside the reciprocating member main body 432, a reciprocating pawl 436 is formed with which a carrier lock tongue 476 of a carrier 462 described later can engage. When the reciprocating pawl 436 engages with the carrier lock tongue 476 described later, the carrier 462 cannot relatively move with respect to the reciprocating member 431. When the reciprocating pawl 436 disengages from the carrier lock tongue 476, the carrier 462 can relatively move with respect to the reciprocating member 431. A reciprocating through-hole 441 is formed in a reciprocating bottom portion 440 of the reciprocating member main body 432. A needle 485 can protrude to the outside of the reciprocating member main body 432 through the reciprocating through-hole 441. A pressing projection 442 is formed in the reciprocating bottom portion 440. The pressing projection 442 can be inserted into a sensor unit groove 138 of the sensor unit 100. The pressing projection 442 is inserted into the sensor unit groove 138 of the sensor unit 100, so that the sensor unit 100 can be fixed in position without moving. A fixing portion 444 is formed inside the reciprocating member 431. The fixing portion 444 is coupled to a needle release driver 490.

[0114] A reciprocating driver 450 is disposed between the column member 410 and the reciprocating member 431. The reciprocating driver 450 can provide a moving force for the reciprocating member 431 to move in the first direction. The reciprocating driver 450 includes a forward elastic member 451 that provides an elastic force capable of moving the reciprocating member 431 in the first direction. One end of the forward elastic member 451 can be coupled to the column member 410, and the other end of the forward elastic member 451 can be coupled to the reciprocating member 431. The reciprocating member 431 is disposed inside the column member 410 in a state where the forward elastic member 451 is elastically deformed. At this time, the reciprocating projection 434 abuts against the operation portion 500, thereby preventing the reciprocating member 431 from moving in the first direction. Then, if the operation portion 500 moves in the third direction so that the reciprocating projection 434 and the operation portion 500 do not abut, the reciprocating member 431 moves in the first direction by the elastic force of the forward elastic member 451. The forward elastic member 451 can be a helical spring, however, the scope of the present invention is not limited thereto.

[0115] The needle assembly 460 may be coupled to the reciprocating member 431, and at least a portion thereof may be disposed within the reciprocating member 431. The needle assembly 460 includes a carrier 462 and a needle 485.

[0116] The carrier 462 is movably coupled to the reciprocating member 431. A portion of the carrier 462 engages with the reciprocating member 431 so as to be movable along a first direction together with the reciprocating member 431. After the carrier 462 completes its movement along the first direction, it can be disengaged from the reciprocating member 431 and move along a second direction. The carrier 462 includes a carrier body 463, at least one carrier wing 471, and at least one clamping arm 478.

[0117] The carrier body 463 is coupled to the needle 485. A fixing portion 469 for coupling a needle release driver 490 described later is provided on the carrier body 463.

[0118] The carrier wing 471 extends from the carrier body 463. At least a portion of the carrier wing 471 can be elastically deformed when moving along the first direction. The carrier wing 471 includes a wing body 472 elastically connected to the carrier body 463, a trigger 474 protruding from the wing body 472, and a carrier latch 476. The trigger 474 can contact the release portion 414 of the post member 410 during the co - movement of the carrier 462 and the reciprocating member 431 along the first direction. The carrier latch 476 protrudes outward from the wing body 472. The carrier latch 476 can engage with the reciprocating pawl 436 of the reciprocating member 431. In a state where the carrier latch 476 engages with the reciprocating pawl 436, the carrier 462 can maintain a state in which the return elastic member 491 of the needle release driver 490 is elastically deformed. Therefore, in a state where the carrier latch 476 engages with the reciprocating pawl 436, the carrier 462 cannot move in the second direction in which the elastic force of the return elastic member 491 acts. As described above, during the co - movement of the carrier 462 and the reciprocating member 431 along the first direction, if the trigger 474 abuts against the release portion 414 and the carrier wing 471 is elastically deformed, the carrier latch 476 disengages from the reciprocating pawl 436.

[0119] The clamping arm 478 is elastically deformably provided on the side of the carrier body 463. A plurality of the clamping arms 478 can be provided on both sides of the carrier body 463 so as to face each other and engage with the sensor unit 100. On the clamping arm 478, there are provided a clamping projection 480 that engages with the sensor unit housing 120 and a protruding portion 482 that abuts against the inner wall 424 of the abutting column member 410. The carrier 462 is coupled to the reciprocating member 431 in such a manner that the carrier body 463 is located inside the reciprocating member 431 and the end of the clamping arm 478 protrudes from the reciprocating member 431. The clamping arm 478 can fix the sensor unit 100 in a manner that engages with the sensor unit housing 120. At this time, the surface of the sensor unit housing 120 abuts against the reciprocating bottom 440 of the reciprocating member 431, and the pressing projection 442 of the reciprocating member 431 is inserted into the sensor unit groove 138 of the sensor unit housing 120.

[0120] As shown in the carrier 462 Figure 9 When the insertion unit assembly 400 is coupled to the dispenser body 300, the sensor unit 100 can be positioned at the first position. When the carrier 462 is at the first position, the protruding portion 482 of the clamping arm 478 abuts against the inner wall 424 of the abutting column member 410. Therefore, the clamping arm 478 can be biased in the direction of engaging with the sensor unit housing 120 and maintain the state in which the carrier 462 and the sensor unit 100 are coupled. On the other hand, when the sensor unit 100 and the carrier 462 move in the first direction and the sensor unit 100 is coupled to the base unit 200, the protruding portion 482 disengages from the inner wall 424 of the column member 410. Therefore, in the state where the sensor unit 100 is coupled to the base unit 200, the fixing force of the clamping arm 478 becomes weak. The sensor unit 100 is coupled to the base unit 200 by the adhesive layer 230, so that when the carrier 462 is pulled by the needle release driver 490 in the second direction away from the sensing device 20, the clamping arm 478 can be separated from the sensor unit 100.

[0121] The needle 485 is coupled to the carrier 462. The needle 485 can assist the sensor 110 when at least a part of the sensor 110 is inserted into the human body. For this purpose, the needle 485 can move together with the sensor unit 100 from the first position in the first direction and be inserted into the user's skin while being coupled to the sensor unit 100. In addition, at the second position where the movement in the first direction is completed, the needle 485 can move in the second direction together with the carrier 462 and be detached from the sensor unit 100. The tip of the needle 485 is formed in a sharp shape so as to pierce the user's skin and smoothly enter the user's skin. When the sensor unit 100 moves in the first direction, the needle 485 pierces the user's skin and enters before the sensor 110, so that the sensor 110 can be stably inserted into the skin. The needle 485 includes a needle body 486 that can be inserted into the user's skin and a needle head 487 coupled to the carrier 462. A needle coupler 489 for fixing the needle head 487 to the carrier 462 is coupled to the needle head 487. The needle coupler 489 is fixed to the inside of the carrier 462 and can fix the needle head 487 to the carrier 462.

[0122] A needle release driver 490 is disposed between the reciprocating member 431 and the needle 485 to move the needle 485 in the second direction. Specifically, one end of the needle release driver 490 is coupled to the reciprocating member 431, and the other end of the needle release driver 490 is coupled to the carrier 462 to which the needle 485 is coupled. The needle release driver 490 can provide a driving force for the movement of the carrier 462 in the second direction. By means of the needle release driver 490, the carrier 462 can move relative to the reciprocating member 431. The needle release driver 490 includes a retraction elastic member 491 in the form of a spring in a stretched state. The retraction elastic member 491 applies an elastic force to the carrier 462 in a direction away from the sensor unit 100. That is, the retraction elastic member 491 can move the carrier 462 and the needle 485 so that the carrier 462 and the needle 485 are detached from the sensor unit 100. One end of the retraction elastic member 491 is coupled to the fixing portion 444 of the reciprocating member 431. During the assembly of the insertion unit 430, one end of the retraction elastic member 491 enters the fixing portion groove 445 through the inlet 448. In the state where one end of the retraction elastic member 491 enters the fixing portion groove 445, it abuts against the contact surface 446 by the elastic force of the retraction elastic member 491. At this time, one end of the retraction elastic member 491 is blocked by the blocking portion 447 and cannot be detached from the fixing portion 444 in a manner of passing through the inlet 448. Therefore, the retraction elastic member 491 can maintain a state of being stably coupled to the fixing portion 444. The other end of the retraction elastic member 491 is fixed to the fixing portion 469 of the carrier 462. The fixing portion 469 of the carrier 462 can also be formed of the same or different structures as the fixing portion 444 of the reciprocating member 431. The retraction elastic member 491 can be a helical spring, but the scope of the present invention is not limited thereto.

[0123] The insertion unit assembly 400 can be combined within the applicator body 300 in a state where the forward elastic member 451 of the reciprocator driver 450 that moves the reciprocator 431 and the backward elastic member 491 of the needle release driver 490 that moves the needle assembly 460 are in an elastically deformed state. Additionally, the insertion unit assembly 400 can be disposed within the applicator body 300 in a state of being combined with the sensor unit 100. According to an embodiment of the present invention, the detailed structure of the insertion unit 430 can form a single assembly together with the column member 410 so as to be simply assembled to the applicator body 300.

[0124] The operation unit 500 is disposed within the applicator body 300. The operation unit 500 is combined with the insertion unit assembly 400 within the applicator body 300. The operation unit 500 is combined with the applicator body 300 in such a way that it moves from a disabled position to an enabled position (moves in the third direction) by means of a user's operation. By the movement of the operation unit 500 in the third direction, the sensor unit 100, the reciprocator 431, and the needle assembly 460 are allowed to move in the first direction. The operation unit 500 includes a button part 510, a limiting part 520, and a limiting part protrusion 535.

[0125] The button part 510 is disposed on the button guide 346 of the intermediate frame 330. The end of the button part 510 can be exposed to the top shell opening 371 of the applicator body 300 through the guide hole 347 of the intermediate frame 330 and is pressed by the user in the third direction. If the user presses the button part 510 exposed outside the top shell 360, the limiting part 520 can also be pressed.

[0126] The limiting part 520 is disposed on the intermediate frame 330. The limiting part 520 prevents or allows the sensor unit 100, the reciprocator 431, and the needle assembly 460 from moving in the first direction. The limiting part 520 includes a limiting part main body 521 and a support part 526. On one end of the upper surface of the limiting part main body 521, the button part 510 extends from the upper surface of the limiting part main body 521. As a non-limiting example, the operation unit 500 can be at least integrally formed by the button part 510 and the limiting part main body 521 with each other.

[0127] The limiting part main body 521 forms the overall appearance of the limiting part 520. The limiting part main body 521 is supported by the platform 331 of the intermediate frame 330. A limiting part opening 522 is formed in the central part of the limiting part main body 521. The insertion unit assembly 400 including the column member 410 is inserted into the limiting part opening 522.

[0128] On one side of the stopper portion main body 521, a stopper portion pawl 524 is formed. The stopper portion 520 cannot move in the third direction in a state where the hook portion 341 of the locking unit 338 of the intermediate frame 330 is engaged with the stopper portion pawl 524. That is, in this case, even if the operation button portion 510 is operated, the stopper portion 520 cannot move from the deactivated position to the activated position. The stopper portion 520 can move to the activated position in a state where the locking main body 339 is disengaged from the stopper portion pawl 524.

[0129] The support portion 526 is configured in a shape protruding from the stopper portion main body 521 on the outer contour of the stopper portion opening 522. The support portion 526 can support the reciprocating member protrusion 434 of the reciprocating member 431. If the stopper portion 520 is in the deactivated position, the support portion 526 can support the reciprocating member protrusion 434 to prevent the reciprocating member 431 from moving in the first direction. If the stopper portion 520 moves in the third direction, that is, the stopper portion 520 is in the activated position, the support portion 526 does not support the reciprocating member protrusion 434, thereby allowing the reciprocating member 431 to move in the first direction.

[0130] The stopper portion protrusion 535 is disposed on the bottom surface side of the stopper portion main body 521. The stopper portion protrusion 535 protrudes from the stopper portion main body 521 so as to be able to abut against one side of the lock hook 360. When the stopper portion 520 is in the deactivated position, the stopper portion protrusion 535 restricts the movement of the lock hook 360 so that the lock hook 360 does not tilt. When the stopper portion 520 is in the activated position, the stopper portion protrusion 535 releases the restriction on the lock hook 360. Specifically, the stopper portion protrusion 535 includes a stopper portion protrusion contact portion 536 and a stopper portion protrusion pawl 537. The stopper portion protrusion contact portion 536 can abut against the upper surface of the extension portion 363 of the lock hook 360 to restrict the tilting movement of the lock hook 360. The stopper portion protrusion pawl 537 can abut against one side portion of the extension portion 363 to push the lock hook 360 to release the fixed mode of the lock hook 360.

[0131] When the stopper portion 520 moves from Figure 19 and Figure 21 the deactivated position shown in (a) to Figure 20 and Figure 21 the activated position shown in (b), the stopper portion protrusion 535 is located above the extension portion 363 of the lock hook 360. At this time, the stopper portion protrusion pawl 537 of the stopper portion protrusion 535 moves the lock hook 360 in the third direction. In the corresponding process, the stopper portion protrusion contact portion 536 of the stopper portion protrusion 535 abuts against the upper surface of the extension portion 363 of the lock hook 360 to restrict the tilting movement of the lock hook 360. Therefore, the lock hook 360 cannot tilt to disengage from the base unit 200. On the other hand, in Figure 20 and Figure 21After the process shown in (b), the operation unit 500 moves in the fourth direction, while the hook 360 is restricted from moving in the fourth direction by the holding projection 327. As a result, the upper surface of the extending portion 363 of the hook 360 is released from the restraint of the limiting portion projection contact portion 536. As a result, the hook 360 can tilt without interfering with the limiting portion projection 535.

[0132] Prevent the operation unit 40 from being combined with the applicator 30 and restrict the movement of the operation unit 500. That is, prevent the operation unit 500 from moving in the third direction (preventing movement from the deactivated position to the activated position) due to the accidental behavior of the user. In addition, prevent the operation unit 40 from moving together with the protective sheet 240 when removed from the applicator 30, causing the protective sheet 240 to separate from the adhesive layer 230. The operation prevention unit 40 includes a moving tongue 600.

[0133] At least a part of the moving tongue 600 can extend from the inside of the applicator main body 300 to the outside through the entrance / exit 322 of the applicator main body 300. The moving tongue 600 can be supported on the platform 320 of the applicator main body 300 and move in the fourth direction.

[0134] The moving tongue 600 restricts the movement of the operation unit 500 including the limiting portion 520. As Figure 9 shown, when the operation unit 500 is in the deactivated position and the moving tongue 600 is inside the applicator main body 300, the moving tongue 600 abuts against the leg portion 342 of the locking unit 338. At this time, the hook portion 341 of the locking unit 338 engages with the limiting portion pawl 524 of the operation unit 500. In this state, the limiting portion 520 is not allowed to move in the third direction. On the other hand, if the moving tongue 600 extends from the entrance / exit 322 and is removed from the applicator main body 300, the locking unit 338 can be disengaged from the operation unit 500 and the operation unit 500 can move.

[0135] The moving tongue 600 is combined with the protective sheet 240. Therefore, if the user moves the moving tongue 600 in the fourth direction to remove the moving tongue 600 from the applicator 30, the protective sheet 240 also moves in the fourth direction. As a result, the protective sheet 240 separates from the adhesive layer 230. The moving tongue 600 includes a moving tongue main body 610 and a base 620.

[0136] The movable tongue body 610 is connected to the protective sheet 240. An insertion hole 611 and a through hole 612 are formed in the movable tongue body 610. In the insertion hole 611, the wing portion 242 of the protective sheet 240 can be inserted. The through hole 612 can be formed in a shape extending in a direction parallel to the moving direction of the base 620. At one end of the movable tongue body 610, a handle portion 614 is arranged, and at the other end of the movable tongue body 610, a movable tongue engaging portion 616 is arranged. When the movable tongue 600 is located inside the applicator body 300, the handle portion 614 is arranged outside the applicator body 300. At the movable tongue engaging portion 616, a hook arm 617 is formed which engages with the applicator body engaging portion 324 of the bottom frame 310. When the movable tongue 600 is located inside the applicator body 300, the hook arm 617 engages with the engaging protrusion 325. If a force above a certain level is applied to the movable tongue 600 in the fourth direction, the hook arm 617 can be disengaged from the engaging protrusion 325. Therefore, the movable tongue 600 can move in the fourth direction.

[0137] The base 620 is movably coupled to the movable tongue body 610. The base 620 includes a clamping portion 621 and a pressing portion 622. In a state where the wing portion 242 of the protective sheet 240 is inserted into the insertion hole 611 of the movable tongue body 610, the clamping portion 621 is inserted into the protective sheet hole 245, so that the protective sheet 240 can be coupled to the movable tongue 600. The pressing portion 622 can protrude from the movable tongue body 610 and press the protective sheet 240 in the first direction. That is, when the movable tongue 600 is located inside the applicator body 300, the pressing portion 622 presses the protective sheet 240 toward the adhesive layer 230 side. Therefore, the bonding force between the protective sheet 240 and the adhesive layer 230 is prevented from becoming weak. The pressing portion 622 can be elastically deformed, so that when the movable tongue 600 moves in the fourth direction, it can abut against the bottom frame 310 and be elastically deformed.

[0138] The protective sheet 50 is coupled to the base unit 200. Specifically, the protective sheet 50 can be coupled to the base unit 200 in a form covering the adhesive portion 250 of the base unit 200. The protective sheet 50 protects the adhesive portion 250 until the user operates the applicator assembly 10 of this embodiment, so that the adhesiveness of the adhesive portion 250 can be maintained. The protective sheet 50 can include a demolding material, and the user can easily remove the protective sheet 50 from the adhesive portion 250 of the base unit 200.

[0139] The following refers to Figures 23 to 27 , and describes the process of attaching the sensing device 20 to the user's skin using the applicator 30 of an embodiment of the present invention.

[0140] First, as Figure 23As shown, the protective sheet 240 is removed by using the moving tongue 600 that prevents the operation unit 40. If the user moves the moving tongue 600 in the fourth direction, the moving tongue 600 removes the protective sheet 240 from the adhesive layer 230 of the base unit 200. On the other hand, if the moving tongue 600 moves in the fourth direction, the locking body 339 is released from the moving tongue 600. At this time, the locking body 339 disengages from the operation unit 500, and the operation unit 500 is converted by the user into a movable state.

[0141] Then, the protective sheet 50 is removed from the adhesive portion 250 of the base unit 200 to expose the adhesive portion 250, and the bottom 312 of the applicator body 300 and the adhesive portion 250 are arranged to abut against the user's skin. On the other hand, different from the foregoing, the operation prevention unit 40 may also be removed after the protective sheet 50 is removed.

[0142] Then, as Figure 24 shown, the operation unit 500 is pressed to move the operation unit 500 in the third direction. Accordingly, the sensor unit 100, the reciprocator 431, and the needle assembly 460 are allowed to move in the first direction. Specifically, if the user presses the button portion 510 of the operation unit 500 in the third direction, the operation unit 500 moves in the third direction while elastically deforming the elastic pressing portion 345 and is located at the enabled position. As the operation unit 500 moves to the enabled position, the reciprocator 431 disengages from the limiting portion 520 and moves in the first direction by means of the forward elastic member 451. As the reciprocator 431 moves in the first direction, the needle 485 and the sensor 110 are inserted into the user's skin, and the sensor unit 100 is attached to the base unit 200 by the adhesive layer 230.

[0143] On the other hand, when the reciprocator 431 moves in the first direction, the trigger 474 of the carrier 462 abuts against the release portion 414 of the column member 410, and the carrier tongue 476 disengages from the reciprocator pawl 436. If the carrier 462 disengages from the reciprocator 431, then as Figure 26 and Figure 27 shown, the carrier 462 moves in the second direction away from the user's skin by means of the backward elastic member 491. At this time, the needle 485 is withdrawn from the user's skin, and the sensing device 20 remains attached to the user's skin by the adhesive portion 250. During the movement of the needle 485 in the second direction, the reciprocator bottom 440 of the reciprocator 431 moving in the first direction remains in contact with the sensor unit 100. Moreover, the pressing projection 442 of the reciprocator 431 may remain inserted into the sensor unit groove 138 of the sensor unit 100.

[0144] After the sensor 110 is inserted into the user's skin, the applicator 30 can be separated from the sensing device 20 attached to the skin. Specifically, if the operation unit 500 is pressed in the third direction, when the operation unit 500 moves in the third direction, the locking hook 360 also moves in the third direction. Then, if the pressure applied to the operation unit 500 in the third direction is released, the operation unit 500 moves in the fourth direction, while the locking hook 360 cannot move in the fourth direction. As a result, the extension 363 of the locking hook 360 is released from the limiting protrusion 535. Thus, the locking hook 360 becomes in a tiltable state. Therefore, as Figure 27 shown, if the user removes the applicator 30 from the sensing device 20, the locking hook 360 tilts and the engagement between the applicator 30 and the sensing device 20 can be released.

[0145] Although one embodiment of the present invention has been described above, those skilled in the relevant technical field can variously revise and change the present invention by adding, changing, deleting, etc. of the components without exceeding the inventive concept described in the claims, and this is also included within the scope of the claims of the present invention.
