[0001] This application claims the benefit of Korean Patent Application No. 10-2025-0023037, filed on February 21, 2025, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. Technical Field

[0002] The example implementation relates to an applicator component, and more specifically to an applicator component for acquiring biometric information. Background Technology

[0003] Modern people suffer from various diseases, and in order to properly treat or manage these diseases, it is necessary to obtain human biometric information.

[0004] Diabetes is a prime example. Proper management of diabetes requires means to obtain blood glucose information as biometric data for individuals with diabetes.

[0005] Recently, continuous glucose monitoring (CGM) devices have been developed, which are inserted into the human body to measure blood glucose levels at intervals of several minutes. CGM devices enable continuous glucose measurement by minimizing the pain and discomfort associated with blood sampling through the insertion of a needle-like sensor into a relatively less painful area, such as the abdomen or arm.

[0006] The continuous glucose monitoring device consists of a sensor unit, a terminal, etc. The sensor unit is attached to the user's body to measure the user's blood glucose information and send the measured blood glucose information. The terminal provides the blood glucose information received from the sensor unit to the user, enabling the user to monitor or manage their blood glucose information.

[0007] The sensor unit consists of a sensor module inserted and attached to the user's skin to measure blood glucose from the user's bodily fluids, and a transmitter that sends the blood glucose level measured by the sensor module to a terminal. The sensor module includes a needle-shaped probe that is inserted into subcutaneous fat to extract interstitial fluid.

[0008] The applicator is used to insert and attach the sensor unit to the body.

[0009] The applicator is configured to insert and attach a sensor unit to the body. During user operation, it inserts and attaches the sensor unit to the body. When the applicator is subsequently detached from and removed from the body while simultaneously inserting and attaching the sensor unit, only the sensor unit remains attached to the body.

[0010] Because a portion of the sensor unit is inserted into the human body, the sensor unit installed inside the applicator and the applicator's internal space must remain sterile from the manufacturing stage until it is used by the consumer. Additionally, dehumidification must be maintained to protect the electronic components. Simultaneously, the applicator's internal space must be sealed and isolated from the outside to maintain its sterility and dehumidification.

[0011] To maintain these sterile, dehumidified, and sealed conditions, various packaging technologies are applied to the applicator, and simplifying packaging and reducing size have become goals for applicator manufacturers.

[0012] Meanwhile, to maintain the applicator's seal, a protective cover is attached to the housing; for use, the user removes the cover from the housing. These sealing structures must maintain the applicator's seal integrity before use and must be designed to ensure no inconvenience to the user during removal. Summary of the Invention

[0013] One aspect is to address at least some of the problems of the prior art mentioned above, and to provide an applicator with improved sealing integrity.

[0014] On the other hand, it also provides an applicator that reduces the force required for the user to remove the protective cover from the applicator assembly.

[0015] According to one aspect, an applicator assembly is provided, comprising: a sensor unit configured to attach to a user's body to acquire the user's biometric information; an applicator including a housing forming an internal space and having an opening on one side, the applicator being configured to attach the sensor unit to the user's body; and a protective cover configured to engage with the housing to cover the opening. The applicator may include a sealing member disposed adjacent to the opening of the housing and configured to seal the internal space of the housing together with the protective cover, and the sealing member may include a first protrusion and a second protrusion projecting outward from a surface of the sealing member and forming steps relative to each other.

[0016] According to an example implementation, the protective cover may cover at least a portion of the outer surface of the housing adjacent to an opening.

[0017] According to an example implementation, the first protrusion may be positioned further from the opening than the second protrusion and protrude more than the second protrusion.

[0018] According to an example embodiment, the protective cover may include a first sealing surface configured to compress a first protrusion and a second sealing surface configured to compress a second protrusion when coupled to the housing.

[0019] According to the example implementation, the first sealing surface and the second sealing surface may form a step relative to each other, and the distance from the surface of the sealing member to the first sealing surface may be greater than the distance from the surface of the sealing member to the second sealing surface.

[0020] According to an example implementation, the distance from the surface of the sealing member to the first sealing surface can be greater than the height of the second protrusion protruding from the surface of the sealing member.

[0021] According to an example embodiment, the first protrusion and the second protrusion may include an elastic material capable of compression deformation. The height by which the first protrusion protrudes from the surface of the sealing member before compression may be greater than the distance from the surface of the sealing member to the first sealing surface, and the height by which the second protrusion protrudes from the surface of the sealing member before compression may be greater than the distance from the surface of the sealing member to the second sealing surface.

[0022] According to an example embodiment, the sealing member may further include a strip configured to cover the outer surface of the housing, and the housing may include a recess configured to receive the strip.

[0023] According to an example implementation, the strip can be configured to be detachably attached to the housing.

[0024] According to an example implementation, the sealing member may be integrally formed with the housing from the same material as the housing.

[0025] According to an example implementation, the first protrusion and the second protrusion may be configured to be detachably attached to the housing and have a ring shape covering the outer surface of the housing.

[0026] According to the example implementation, the first protrusion and the second protrusion may have a circular cross-section, and the cross-sectional area of ​​the first protrusion may be formed to be larger than the cross-sectional area of ​​the second protrusion.

[0027] According to an example implementation, the surface of the sealing member may be inclined toward the interior of the housing as it approaches the opening.

[0028] According to an example implementation, the inner surface of the protective cover facing the sealing member may be inclined along the inclined surface of the sealing member.

[0029] According to an example embodiment, the sealing member may be formed of a material capable of compression deformation and includes at least one of synthetic resin, rubber, or silicone resin.

However, the present disclosure may be embodied in various different forms and is not limited to the exemplary embodiments described herein.

[0056] In the following, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0057] Figure 1 This is a perspective view showing an applicator assembly 1 according to an exemplary embodiment of the present disclosure. Figure 2 This is a perspective view showing the applicator 10 according to an exemplary embodiment of the present disclosure and the sensor unit 900 assembled to the applicator 10, viewed from another direction. Figure 3 It shows along Figure 1 An exemplary diagram of a cross-sectional view of line I-I' in the diagram. Figure 2 It shows Figure 1 The state of the applicator 10, wherein the indicator member 1200 is removed and the protective cover 1000 is removed.

[0058] refer to Figures 1 to 3 The applicator assembly 1 according to an exemplary embodiment of the present disclosure may include an applicator 10. The applicator 10 may be configured to attach the sensor unit 900 to a user's body. For example, the applicator 10 may internally house the sensor unit 900 before use and trigger the sensor unit 900 during use to attach the sensor unit 900 to the user's skin.

[0059] The applicator 1 according to an exemplary embodiment of the present disclosure may include a housing 100.

[0060] According to an exemplary embodiment of this disclosure, the housing 100 may be a component protecting the applicator 10 and the sensor unit 900, and forms the external shape of the applicator 10. The housing 100 may form an internal space. The housing 100 may have a specific space inside capable of accommodating other components. In this case, the housing 100 may have an open side. Alternatively, the housing 100 may include an opening 110. The opening 110 may be an open portion on one side of the housing 100. The opening 110 may be formed at an end of the housing 100.

[0061] An applicator assembly 1 according to an exemplary embodiment of the present disclosure may include an indicator member 1200. The indicator member 1200 may be adhered between a protective cover 1000 and a housing 100. At least a portion of the protective cover 1000 may be coupled to the housing 100 such that it covers an outer surface of the housing 100. The indicator member 1200 may surround adjacent outer surfaces between the housing 100 and the protective cover 1000, and the gap between the housing 100 and the protective cover 1000. At least a portion of the housing 100 may include an outwardly projecting protrusion 220. The surface of the protrusion 220 may be flush with the outer surface of the protective cover 1000. The indicator member 1200 may be adhered to the protrusion 220 and the outer surface of the protective cover 1000. The indicator member 1200 may be configured to leave a mark on the outer surface of the housing 100 or the protective cover 1000 when removed from the housing 100 or the protective cover 1000. Therefore, the user can determine whether the sterilization, dehumidification, and sealing conditions inside the applicator 10 have been compromised by checking whether the indicator component 1200 has been removed. Additionally, the indicator component 1200 can be adhesively wrapped between the housing 100 and the protective cover 1000 to seal and isolate the interior of the applicator 10 from the exterior.

[0062] The applicator assembly 1 according to an exemplary embodiment of the present disclosure may include a protective cover 1000. The protective cover 1000 may be coupled to the housing 100 of the applicator 10. Specifically, the protective cover 1000 may be detachably coupled to the housing 100. The protective cover 1000 may be configured to cover an opening 110 in the housing 100. The protective cover 1000 may be coupled to the housing 100 in one direction such that the opening 110 is not exposed to the outside. After removing the indicator member 1200 before use, the user can remove the protective cover 1000 from the housing 100 by pulling it to one side.

[0063] In an exemplary embodiment of this disclosure, the protective cover 1000 may be formed to cover at least a portion of the outer peripheral surface of the housing 100 adjacent to the opening 110. For example, the protective cover 1000 may be formed to cover at least a portion of the outer peripheral surface of an end of the housing 100. The protective cover 1000 may have a recessed stop shape for insertion into the opening 110 of the housing 100.

[0064] A protective cover 1000 according to an exemplary embodiment of the present disclosure may include a pillar portion 1010 and an outer wall portion 1020. The pillar portion 1010 may be a portion inserted into the interior of the housing 100, and the outer wall portion 1020 may be a portion covering the outer surface of the housing 100. The pillar portion 1010 may cover the inside of the opening 110, and the outer wall portion 1020 may cover the outside of the opening 110. For example, a groove may be formed between the pillar portion 1010 and the outer wall portion 1020 of the protective cover 1000 to allow insertion into an end of the housing 100. The pillar portion 1010 may cover the inside of an end of the housing 100, and the outer wall portion 1020 may cover the outside of an end of the housing 100.

[0065] A protective cover 1000 according to an exemplary embodiment of the present disclosure may include a first cover member 1060, a dehumidifying member 1070, and a second cover member 1080. The first cover member 1060, the dehumidifying member 1070, and the second cover member 1080 may be accommodated within the protective cover 1000. The protective cover 1000 has holes of various sizes arranged sequentially and penetrating on one side, and the first cover member 1060 and the second cover member 1080 may seal at least one of the holes of various sizes. The dehumidifying member 1070 may be positioned between the first cover member 1060 and the second cover member 1080. The first cover member 1060, the dehumidifying member 1070, and the second cover member 1080 may be arranged sequentially along a single direction.

[0066] According to exemplary embodiments of the present disclosure, the first cover member 1060 and the second cover member 1080 may be formed of different materials. The first cover member 1060 may be formed of a material having bacterial barrier properties that prevent bacterial passage and also being breathable. The first cover member 1060 may include a porous filter structure. Therefore, even when sterilizing gas is injected while the first cover member 1060 seals the holes on the protective cover 1000, the sterilizing gas can pass through the first cover member 1060 and be injected into the internal space of the housing 100. However, the porous filter structure of the first cover member 1060 can be formed small enough to prevent bacterial passage. Therefore, external bacteria can be prevented from passing through the first cover member 1060.

[0067] The dehumidification component 1070 according to an exemplary embodiment of this disclosure can be a structure for removing moisture. For example, the dehumidification component 1070 may include various desiccants for absorbing moisture.

[0068] The second cover member 1080 according to an exemplary embodiment of this disclosure may be formed of a moisture-proof material. For example, the second cover member 1080 may be an aluminum film. Therefore, external moisture may not be able to penetrate the second cover member 1080.

[0069] refer to Figure 3 According to an exemplary embodiment of this disclosure, the first cover member 1060, the dehumidifying member 1070, and the second cover member 1080 are housed in a three-layer structure within the protective cover 1000, thereby maintaining the internal environment of the housing 100 in a sterilized, dehumidified, and sealed state. After sterilizing the internal space of the housing 100 by injecting sterilizing gas via the first cover member 1060, the dehumidifying member 1070 is positioned to regulate humidity, and the second cover member 1080 is placed on the outside to form a structure that prevents external bacteria or moisture from penetrating into the internal space of the housing 100.

[0070] The applicator assembly 1 according to an exemplary embodiment of this disclosure may include a sensor unit 900. The sensor unit 900 may be configured to acquire a user's biometric information. For example, the sensor unit 900 may be attached to the user's skin S, with at least a portion inserted into the skin S to acquire the user's biometric information. Furthermore, the sensor unit 900 may be configured to transmit the acquired user's biometric information. For example, the sensor unit 900 may transmit the user's biometric information to a portable terminal, thereby allowing the user to check their biometric information via the portable terminal.

[0071] Figure 4 It is shown Figure 3 An example diagram of a magnified view of region A in the image. Figure 5 It is shown Figure 3 An example diagram of a magnified view of region A in the image. Figure 6 This shows the protective cover 1000 being removed from... Figure 5 A diagram showing the process of removing the applicator 10. Figure 7 This shows the protective cover 1000 being removed from... Figure 5 A diagram showing the process of removing the applicator 10. Figures 5 to 7 The diagram shows the state after the indicator component 1200 has been removed to detach the protective cover 1000. The protective cover 1000 can be pressed from... Figures 5 to 7 The order is unloaded in one direction.

[0072] refer to Figures 4 to 7 The applicator 10 according to an exemplary embodiment of the present disclosure may include a sealing member 1100.

[0073] According to an exemplary embodiment of this disclosure, the sealing member 1100 may be positioned adjacent to the opening 110 of the housing 100. The sealing member 1100 may be positioned close to the opening 110. The sealing member 1100 may be positioned at a predetermined distance from the opening 110. However, this does not preclude the possibility that the sealing member 1100 may be positioned to contact the opening 110.

[0074] According to an exemplary embodiment of this disclosure, the sealing member 1100 can be configured to seal the internal space of the housing 100 together with the protective cover 1000. For example, the sealing member 1100 can be disposed between the housing 100 and the protective cover 1000 to seal the internal space of the housing 100. The sealing member 1100 can fill any void space that may be formed between the protective cover 1000 and the housing 100. Specifically, the outer wall portion 1020 of the protective cover 1000 can internally contact the sealing member 1100. The sealing member 1100 can be positioned between the outer peripheral surface of the housing 100 adjacent to the opening 110 and the outer wall portion 1020.

[0075] According to an exemplary embodiment of the present disclosure, the sealing member 1100 may include a first protrusion 1121 and a second protrusion 1122. The first protrusion 1121 and the second protrusion 1122 may protrude outwardly from a surface 1130 of the sealing member 1100. The first protrusion 1121 and the second protrusion 1122 may protrude in a direction intersecting with the surface 1130 of the sealing member 1100. For example, the first protrusion 1121 and the second protrusion 1122 may protrude toward a protective cover 1000 coupled to the housing 100.

[0076] According to an exemplary embodiment of this disclosure, the first protrusion 1121 and the second protrusion 1122 may form a step relative to each other. For example, the first protrusion 1121 may protrude more than the second protrusion 1122. (See reference...) Figures 5 to 7 The height of the first protrusion 1121 protruding from the surface 1130 of the sealing member 1100 can be greater than the height of the second protrusion 1122.

[0077] According to an exemplary embodiment of this disclosure, the first protrusion 1121 can be positioned relatively higher than the second protrusion 1122. In other words, the first protrusion 1121 can be positioned further away from the opening 110 than the second protrusion 1122. In other words, the distance between the opening 110 and the first protrusion 1121 can be greater than the distance between the opening 110 and the second protrusion 1122. Furthermore, the first protrusion 1121 and the second protrusion 1122 may not be physically connected to each other and may maintain different heights.

[0078] The protective cover 1000 according to an exemplary embodiment of the present disclosure may include a first sealing surface 1021 and a second sealing surface 1022. When the protective cover 1000 is attached to the housing 100, the first sealing surface 1021 may be configured to compress the first protrusion 1121, and the second sealing surface 1022 may be configured to compress the second protrusion 1122. When the protective cover 1000 is attached to the housing 100, the first sealing surface 1021 and the second sealing surface 1022 may be portions that respectively contact the first protrusion 1121 and the second protrusion 1122.

[0079] The first protrusion 1121 and the second protrusion 1122 according to exemplary embodiments of the present disclosure may include an elastic material capable of compression deformation. For example, the first protrusion 1121 and the second protrusion 1122 may include at least one compressible material, such as synthetic resin, rubber, or silicone resin.

[0080] According to an exemplary embodiment of this disclosure, the height by which the first protrusion 1121 protrudes from the surface 1130 of the sealing member 1100 before compression may be greater than the distance from the surface 1130 of the sealing member 1100 to the first sealing surface 1021. Figure 5 To explain the aforementioned distance difference, it is shown that at least a portion of the first protrusion 1121 extends beyond the first sealing surface 1021, without depicting the actual protective cover 1000 connected to the housing 100 when the first protrusion 1121 is in a compressed state. Therefore, the first protrusion 1121 can protrude sufficiently to be compressed by the first sealing surface 1021 and seal the space between the housing 100 and the protective cover 1000.

[0081] According to an exemplary embodiment of this disclosure, the height by which the second protrusion 1122 protrudes from the surface 1130 of the sealing member 1100 before compression may be greater than the distance from the surface 1130 of the sealing member 1100 to the second sealing surface 1022. Figure 5 To explain the aforementioned distance difference, it is shown that at least a portion of the second protrusion 1122 extends beyond the second sealing surface 1022, without depicting the actual protective cover 1000 connected to the housing 100 when the second protrusion 1122 is in a compressed state. Therefore, the second protrusion 1122 can protrude sufficiently to be compressed by the second sealing surface 1022 and seal the space between the housing 100 and the protective cover 1000.

[0082] According to an exemplary embodiment of this disclosure, the first protrusion 1121 and the second protrusion 1122 can double-seal the applicator 10. The first protrusion 1121 and the second protrusion 1122 can be spaced apart from each other. The first protrusion 1121 and the second protrusion 1122 can seal the space between the housing 100 and the protective cover 1000 while being spaced apart. Therefore, even if a defect occurs in the first protrusion 1121 that is positioned relatively outward from the second protrusion 1122, preventing a smooth seal, the second protrusion 1122 can compensate for the integrity of the seal.

[0083] According to an exemplary embodiment of this disclosure, the first sealing surface 1021 and the second sealing surface 1022 may form steps relative to each other. The second sealing surface 1022 may protrude further toward the sealing member 1100 than the first sealing surface 1021. In other words, the distance from the surface 1130 of the sealing member 1100 to the first sealing surface 1021 may be greater than the distance from the surface 1130 of the sealing member 1100 to the second sealing surface 1022. In this case, the protective cover 1000 may be in a state of being connected to the housing 100.

[0084] According to an exemplary embodiment of this disclosure, the first sealing surface 1021 can be positioned so as not to contact the second protrusion 1122 when the protective cover 1000 is removed. For example, the distance from the surface 1130 of the sealing member 1100 to the first sealing surface 1021 can be greater than the height by which the second protrusion 1122 protrudes from the surface 1130 of the sealing member 1100. Reference Figures 5 to 7 The protective cover 1000 can be removed from the housing 100 by moving in one direction. At this time, the first sealing surface 1021 can move in one direction while compressing the first protrusion 1121, thereby causing friction with the first protrusion 1121. Similarly, the second sealing surface 1022 can move in one direction while compressing the second protrusion 1122, thereby causing friction with the second protrusion 1122. The protective cover 1000 can be moved sufficiently such that the first sealing surface 1021 and the second sealing surface 1022 can respectively release contact with the first protrusion 1121 and the second protrusion 1122. If the protective cover 1000 moves further in one direction, the first sealing surface 1021 can face the first protrusion 1121. At this time, since the first sealing surface 1021 is farther from the surface 1130 of the sealing member 1100 than the second protrusion 1122, the second protrusion 1122 and the first sealing surface 1021 can not contact each other. In other words, during the process of removing the protective cover 1000 from the housing 100, the first sealing surface 1021 can avoid friction with the second protrusion 1122. Therefore, when the user removes the protective cover 1000 from the housing 100, the force burden that the user must apply can be reduced.

[0085] The sealing member 1100 according to an exemplary embodiment of this disclosure may further include a band 1110. The band 1110 may have a band shape and be configured to cover the outer peripheral surface of the housing 100. For example, the band 1110 may have a loop shape, such as an elastic band. In this case, the housing 100 may include a recess 210 for receiving the band 1110. The recess 210 may have a shape corresponding to the outer peripheral surface of the band 1110 to engage with the band 1110. The band 1110 may be received in the recess 210 to be coupled to the housing 100. The band 1110 may be formed of a different material than the housing 100, thereby allowing the band 1110 to be configured for detachable coupling to the housing 100. Alternatively, the band 1110 may be formed together with the housing 100 using a dual injection molding process. A first protrusion 1121 and a second protrusion 1122 may each be formed to project outwardly from the band 1110.

Figure 9 It shows from Figure 3 An exemplary diagram of the applicator 10 according to yet another example embodiment of this disclosure, enlarged in region A.

[0087] The sealing member 1100 can be formed in various shapes and materials. Figures 4 to 7 The sealing member 1100 shown may be only one of several examples. In the following, reference is made to... Figures 8 to 9 This describes another form of the sealing member 1100.

[0088] refer to Figure 8 The sealing member 1100 can be formed of the same material as the housing 100 and can be integrally formed with the housing 100. For example, if the housing 100 is made of plastic, the sealing member 1100 can also be made of plastic. However, even if the sealing member 1100 is integrally formed with the housing 100 and made of the same plastic material, the plastic densities of the sealing member 1100 and the housing 100 can be different. The sealing member 1100 can be integrally formed with the housing 100, wherein the first protrusion 1121 and the second protrusion 1122 are formed to protrude from the outer surface of the housing 100. The first protrusion 1121 and the second protrusion 1122 can also be formed of plastic and can be compressed to a predetermined degree by the pressing pressure of the first sealing surface 1021 and the second sealing surface 1022 to form a seal.

[0089] refer to Figure 9The first protrusion 1121 and the second protrusion 1122 can be configured to be detachably connected to the housing 100. For example, the first protrusion 1121 and the second protrusion 1122 can have an annular structure covering the outer peripheral surface of the housing 100. The first protrusion 1121 and the second protrusion 1122 can be formed of a different material than the housing 100. The first protrusion 1121 and the second protrusion 1122 can each be connected to the housing 100 individually. In this case, a portion of the outer surface of the housing 100 can be formed with a groove to receive at least a portion of the first protrusion 1121 and the second protrusion 1122. The first protrusion 1121 and the second protrusion 1122 have a circular cross-section, and the cross-sectional area of ​​the first protrusion 1121 can be formed to be larger than the cross-sectional area of ​​the second protrusion 1122. Therefore, the first protrusion 1121 and the second protrusion 1122 can form a step.

[0090] Figure 10 It shows from Figure 6 A schematic diagram of the applicator 10 according to yet another exemplary embodiment of this disclosure, enlarged in region B.

[0091] Let's refer to each other. Figure 10 and Figure 6 According to another exemplary embodiment of the present disclosure, the surface 1130 of the sealing member 1100 may be formed to be inclined. For example, the surface 1130 of the sealing member 1100 may be inclined toward the housing 100 or the interior of the sealing member 1100 as it approaches the opening 110. In this case, a step may be formed between the first protrusion 1121 and the second protrusion 1122 without changing the dimensions of the first protrusion 1121 and the second protrusion 1122 themselves. The starting point of the second protrusion 1122 may be positioned relatively inward compared to the starting point of the first protrusion 1121.

[0092] According to yet another exemplary embodiment of the present disclosure, the inner surface of the protective cover 1000 may be formed to be inclined. For example, the inner surface of the surface 1130 of the protective cover 1000 facing the sealing member 1100 may be inclined together with the inclined surface 1130 of the sealing member 1100. The first sealing surface 1021 and the second sealing surface 1022 may be inclined toward the interior of the protective cover 1000.

[0093] Figure 11 This is a cross-sectional view showing the state of the applicator 10 according to an exemplary embodiment of the present disclosure before triggering. Figure 12 It is shown Figure 10 A cross-sectional view of the button portion 510 of the applicator 10 being pressed. Figure 13 It is shown Figure 10 A cross-sectional view of the state of the applicator 10 after it is triggered.

[0094] Common Reference Figures 11 to 13 and Figure 3 According to an exemplary embodiment of this disclosure, the housing 100 may include a main housing 200 and an inner housing 300. The main housing 200 may be a component forming an external shape, and the inner housing 300 may be a component attached to the inside of the main housing 200. As used herein, the term "inner side" may refer to the internal space formed by the main housing 200. The main housing 200 may be a dome-shaped component open on one side, and the inner housing 300 may be inserted and assembled through the open side. The inner housing 300 may have an open surface on one side. For example, the inner housing 300 may include the aforementioned opening 110. The sensor unit 900 is detachably attached to the housing 100 and may be discharged through the opening 110 during use. The sensor unit 900 may be inserted and assembled through the opening 110, or discharged during a triggering phase.

[0095] The housing 100 according to an exemplary embodiment of the present disclosure may include an operating portion 500. The operating portion 500 may be a portion manipulated by a user to operate the applicator 10. The operating portion 500 is coupled to the housing 100 and may seal the open side surface of the housing 100. For example, the housing 100 may include a button hole formed through at least a portion of its outer surface, thereby allowing at least a portion of the operating portion 500 to move in and out when a user presses the button portion 510. The button hole may be formed by penetrating a portion of the outer surface of the main housing 200. In this case, the operating portion 500 may seal the button hole.

[0096] The operating portion 500 according to an exemplary embodiment of the present disclosure may include a pleated portion 520. The pleated portion 520 may be formed thinner than its surrounding portions. The pleated portion 520 may be formed thinner than other portions of the operating portion 500 connected to the pleated portion 520 to facilitate elastic deformation.

[0097] The operating part 500 according to an exemplary embodiment of the present disclosure may include an engagement cover 530. The engagement cover 530 may provide an area for engagement with the housing 100.

[0098] The operating unit 500 according to an exemplary embodiment of the present disclosure may include a push rod 540. The push rod 540 protrudes from the button portion 510 toward the internal space. The push rod 540 protrudes toward the internal space and contacts the trigger 400. The trigger 400 is actuated by the push rod 540 and can release the stop state of the plunger 700, causing the plunger 700 to move toward one side of the housing 100 while stopping near the center of the internal space.

[0099] When the button portion 510 according to the exemplary embodiment of this disclosure is pressed and moved toward the inner space side, the push rod 540 can also move toward the inner space side. The push rod 540 can push the trigger 400 toward the inner space side to release the stop state of the plunger. That is, the push rod 540 can be arranged to press the trigger 400 toward the inner space side.

[0100] The push rod 540 according to an exemplary embodiment of this disclosure can be configured to reliably actuate the trigger 400. For example, the push rod 540 can be configured to have a higher density than other parts of the operating portion 500. The operating portion 500 can be formed of an elastic material capable of elastic deformation and recovery as described above, and can be formed of a material different from that of the housing 100. When the operating portion 500 is formed together with the housing 100 using a dual injection molding process, sufficient time and pressure can be applied to the push rod 540 to form a push rod with a high density. The push rod 540 is formed with a high density, and therefore can have sufficient stiffness to apply an external force to the trigger 400.

[0101] Furthermore, the internal space side end of the push rod 540 according to the exemplary embodiment of this disclosure may be formed with a curved surface. Since the push rod 540 is formed of an elastic material, it is capable of elastic deformation. The end of the push rod 540 formed with a curved surface can gradually increase the contact area with the trigger 400 during the process of applying an external force to the trigger 400.

[0102] The operating portion 500 according to an exemplary embodiment of this disclosure may include a support rod 550. The operating portion 500 is formed of an elastic material, and the button portion 510 may be formed thinly. Therefore, during the process of pressing the button, the button portion 510 may twist, causing the push rod 540 to deviate and fail to align with the trigger 400. The support rod 550 may be provided to stably hold the push rod 540 in position. The support rod 550 may extend upward from the push rod 540. The support rod 550 has a rod shape to adequately support the push rod 540 and may be connected to the inside of the engagement cover 530 and the button portion 510.

[0103] The applicator 10 according to an exemplary embodiment of this disclosure may include a plunger 700. The plunger 700 may be disposed within the internal space of the housing 100. Specifically, the plunger 700 may be disposed within the internal space of the inner housing 300. In this case, a first elastic member 600 may be inserted between the plunger 700 and the inner housing 300. The first elastic member 600 may be inserted in a compressed state, and thus may expand upon triggering to move the plunger 700.

[0104] According to an exemplary embodiment of this disclosure, the inner housing 300 can guide the movement of the plunger 700 toward the opening 110. For example, the inner housing 300 can guide the movement of the plunger 700 in one direction. At least a portion of the internal shape of the inner housing 300 can be formed to correspond to a portion of the external shape of the plunger 700, and the inner housing 300 can include a space allowing the plunger 700 to move toward the opening 110. The plunger 700 can be guided by at least a portion of the inner surface of the inner housing 300 to move toward the opening 110.

[0105] According to an exemplary embodiment of this disclosure, the plunger 700 can move the sensor unit 900 toward the opening 110. For example, the sensor unit 900 can move toward the opening 110. The sensor unit 900 can be configured to acquire a user's biometric information. The plunger 700 can move toward the opening 110 via the first elastic member 600, and in doing so, can move toward the opening 110 together with the sensor unit 900.

[0106] The applicator 10 according to an exemplary embodiment of this disclosure may further include a trigger 400. The trigger 400 can hold the plunger 700 in a stationary state and can release the plunger 700 from the stationary state during movement. The user can move the trigger 400 by pressing the button portion 510 of the aforementioned operation portion 500.

[0107] An applicator 10 according to an exemplary embodiment of this disclosure may include a needle assembly 800. Upon triggering, the needle assembly 800 moves a needle 830 toward an opening 110, and the moved needle 830 may pierce a portion of the user's skin S. The needle assembly 800 may retract the needle 830 at a specific point after triggering by moving the needle 830 in the opposite direction of its initial movement. For example, the needle 830 may move toward the opening 110 to pierce a portion of the user's skin S, and then move in the opposite direction to retract.

[0108] In this specification, the plunger 700, sensor unit 900, needle assembly 800, and needle 830 are depicted in the accompanying drawings as moving in a vertical direction. However, this is merely an example and the direction of movement is not necessarily limited to vertical. This direction can be appropriately modified as long as the needle 830 can pierce the user's skin S and the sensor unit 900 can be attached to the user's skin S. For example, although the opening 110 is open on one side of the housing 100, the needle 830 can be triggered and moved in a direction intersecting the direction toward the opening 110 to pierce a portion of the user's skin S. Similarly, it is possible for the direction in which the protective cap 1000 is attached to or removed from the housing 100 to intersect the direction of movement of the needle 830.

[0109] According to an exemplary embodiment of this disclosure, the needle assembly 800 can be inserted into the interior of the plunger 700. Specifically, the needle assembly 800 can be accommodated in a space provided by protruding from the upper part of the plunger 700, and the sensor unit 900 can be positioned below the needle assembly 800.

[0110] Figure 11 The applicator 10 is shown in its state before triggering. (Reference) Figure 11 In order to use the applicator 10, the user can remove the protective cover 1000 and position the applicator 10 so that the opening 110 of the housing 100 contacts the user's skin S.

[0111] According to an exemplary embodiment of this disclosure, the plunger 700 can hold the sensor unit 900. A receiving seat 720 is provided at the lower portion of the plunger 700 facing the opening 110, and the receiving seat 720 forms a predetermined space to accommodate the sensor unit 900. At least one hook 710 may be formed around the receiving seat 720. The hook 710 is bent at one end, and the bent portion of the hook 710 can support at least a portion of the sensor unit 900. The sensor unit 900 supported by the hook 710 can be held fixed within the receiving seat 720.

[0112] According to an exemplary embodiment of this disclosure, the plunger 700 can be in a stopped state near the center height of the housing 100. At this time, the first elastic member 600 disposed between the plunger 700 and the inner housing 300 can be in a compressed state. Before triggering, a trigger 400, positioned relatively to the left in the drawings, engages at least a portion of the plunger 700 and can fix the plunger 700 to prevent it from being moved by the first elastic member 600. That is, the trigger 400 can hold the plunger 700 in a fixed state.

[0113] A sensor unit 900 according to an exemplary embodiment of this disclosure includes a probe 910 inserted into the body, wherein the probe 910 may protrude to one side. For example, in a pre-trigger state, the probe 910 may protrude toward an opening 110. An adhesive layer 920 may be formed on the lower portion of the body of the sensor unit 900. The adhesive layer 920 adheres to the human body, allowing the sensor unit 900 to be secured to the skin S.

[0114] According to an exemplary embodiment of this disclosure, the needle assembly 800 can be housed on the upper part of the plunger 700. The needle 830 has a sharp tip capable of piercing the skin S and forms an inner cavity to accommodate the probe 910.

[0115] The user can position the applicator 10 at the application site and then press the button 510 of the operation unit 500 to trigger the applicator 10.

[0116] Figure 12 This shows the state where button 510 is pressed. Figure 13 The state after triggering is shown. (Reference) Figures 12 to 13 The plunger 700 moves toward the opening 110 to attach the sensor unit 900 to the skin S.

[0117] The user can press the button portion 510 toward the interior space side of the housing 100. At this time, the push rod 540 located on the inner side of the button portion 510 can move toward the interior space side. One end of the push rod 540 presses the trigger 400, so the trigger 400 can move toward the interior space side. One surface of the trigger 400 can contact the push rod 540, and the opposite surface can contact the return member 320. The return member 320 is a component provided in the inner housing 300 and can elastically deform to move the trigger 400 back to its original position. For example, when the user releases the button portion 510, the trigger 400 can return to its original position via the return member 320.

[0118] The trigger 400, which moves toward the interior space, can release the plunger 700 from its stopped state. Due to the expansion of the compressed first elastic member 600, the plunger 700 can move toward the opening 110.

[0119] According to an exemplary embodiment of this disclosure, the sensor unit 900 and needle assembly 800 can move together with the plunger 700 toward the opening 110.

[0120] According to an exemplary embodiment of the present disclosure, the needle 830 of the needle assembly 800 can move toward the opening 110 to pierce the skin S to a certain depth. A probe 910 located within the needle 830 can be inserted into a hole formed in the skin S by the needle 830. An adhesive layer 920 of the sensor unit 900 is attached to the surface of the skin S, and the sensor unit 900 can be fixed to the skin S when the probe 910 is inserted into the skin S.

[0121] According to an exemplary embodiment of this disclosure, the inner housing 300 may have an inner wall that guides the movement of the hook 710 along its movement path. The inner wall of the inner housing 300 may widen outward toward the opening 110. One surface of the hook 710 may move while in contact with the inner wall of the inner housing 300. Upon reaching the end of the housing 100, the hook 710 may rotate. Due to the rotation of the hook 710, the bent portion of the hook 710 supporting the lower part of the sensor unit 900 moves away from the sensor unit 900, and the hook 710 may release the sensor unit 900 from its fixation.

[0122] The needle assembly 800 according to an exemplary embodiment of the present disclosure may include a retrieval portion 820. One end of the retrieval portion 820 may hold the needle 830. The retrieval portion 820 may be secured by engaging a portion of the frame of the needle assembly 800. When the needle assembly 800 moves toward the opening 110 such that the needle 830 penetrates the skin S to a certain depth, the retrieval portion 820 may be pressed inward by the inner housing 300. At this time, the retrieval portion 820 may be released from engagement with the frame of the needle assembly 800.

[0123] The needle assembly 800 according to an exemplary embodiment of the present disclosure may include a second elastic member 810. The second elastic member 810 may be coupled to the retrieval portion 820 in a stretched state. When the retrieval portion 820 is released from engagement with the frame of the needle assembly 800, the second elastic member 810 pulls the retrieval portion 820 in the opposite direction of its movement.

[0124] The needle 830 can be retrieved by the retrieval section 820 according to an exemplary embodiment of the present disclosure in the opposite direction of its movement and housed within the needle assembly 800. The retrieved needle 830 is not exposed to the outside, thereby preventing injury to the user.

[0125] The mechanisms and configurations related to the triggering of the applicator 10 described above are merely illustrative examples. Therefore, different triggering mechanisms may also be applied to the applicator 10.

[0126] Figure 14 This is a perspective view showing the state of the applicator 10 according to an exemplary embodiment of the present disclosure, wherein the protective cover 1000 is removed. Figure 15 The applicator 10 according to an exemplary embodiment of this disclosure is in a state prior to triggering. Figure 1 The sectional view taken by section line II-II'. Figure 16 It is shown Figure 14 A cross-sectional view of the state after the trigger.

[0127] refer to Figures 14 to 16 According to an exemplary embodiment of this disclosure, the vent 310 can provide a path for air within the interior space of the housing 100 to be discharged to the outside. Specifically, the vent 310 can provide a path for air pushed out by a plunger 700 moving toward the opening 110 during triggering to be discharged to the outside of the housing 100.

[0128] According to an exemplary embodiment of this disclosure, the vent 310 may be spaced apart from the sealing member 1100 toward the opening 110. For example, the vent 310 may be further spaced apart from the sealing member 1100 in the direction toward the opening 110. The vent 310 is an opening configured to allow air to escape from the interior space of the housing 100 to the outside, and to communicate with the outside when the protective cover 1000 is removed. The interior space of the housing 100 needs to be kept sealed before the applicator 10 is used, and the vent 310 can be sealed. Therefore, when the protective cover 1000 is attached to the housing 100, the vent 310 may be positioned closer to the opening 110 than the sealing member 1100 to prevent communication with the outside.

[0129] In an exemplary embodiment of this disclosure, the vent 310 may include a first vent 311 and a second vent 312. The first vent 311 and the second vent 312 may form a stepped structure relative to each other. A step difference may be formed between the first vent 311 and the second vent 312. The step difference may be oriented toward the opening 110. The second vent 312 may be positioned closer to the opening 110 than the first vent 311 and may be positioned on the inner side. During use, at least one surface of the second vent 312 may contact the user's skin S and may be located at an end of the housing 100. At least a portion of the second vent 312 may include a downwardly open configuration. Therefore, air discharged by the plunger 700 moving in one direction can be discharged to the outside through the second vent 312 until the trigger state ends.

[0130] At least a portion of the vent 310 according to an exemplary embodiment of the present disclosure may be formed between the opening 110 of the housing 100 and the sealing member 1100. For example, a first vent 311 may be positioned between an end of the housing 100 and the sealing member 1100. The first vent 311 is formed to be spaced apart from the end of the housing 100, thereby preventing weakening of the rigidity of one end of the housing 100.

[0131] According to an exemplary embodiment of this disclosure, the first vent 311 may be an opening facing the outer side of the housing 100. For example, when the main housing 200 and the inner housing 300 are combined, the first vent 311 may have a shape that is radially open based on the longitudinal direction of the housing 100.

[0132] According to an exemplary embodiment of this disclosure, the first vent 311 and the second vent 312 can be connected to each other. For example, the first vent 311 and the second vent 312 can be connected to each other in a layered manner. At least a portion of the first vent 311 can be located above at least a portion of the second vent 312, such that they are in communication with each other.

[0133] According to the example implementation, the sealing integrity of the applicator can be improved.

[0134] According to the example implementation, the force required by the user can be reduced when the user removes the protective cover of the applicator.

[0135] The foregoing description has illustrated and explained the present disclosure with respect to preferred embodiments used to illustrate the principles of the present disclosure. However, the present disclosure is not limited to the construction and operation shown and described herein.
