Description

Technical Field

[0001] The utility model generally relates to the field of medical instruments, and in particular to an application device. Background Art

[0002] At present, the main ways for diabetic patients to monitor their blood sugar include traditional finger blood test (Blood Glucose Monitoring, BGM) and continuous blood glucose monitoring (Continuous Glucose Monitoring, CGM). Among them, continuous blood glucose monitoring can detect the patient's blood sugar level in real time, and has the ability to detect hidden hyperglycemia and hypoglycemia that are not easily detected by traditional finger blood test methods, becoming a new trend in blood sugar monitoring.

[0003] A continuous blood glucose monitoring device generally includes a glucose sensor inserted under the skin to monitor the glucose concentration of subcutaneous tissue fluid in real time, and an electronic device electrically connected to the glucose sensor and applied to the surface of the skin. In order to insert the glucose sensor under the skin and apply the electronic device on the skin, an application device is generally required. Specifically, the application device may include a puncture assembly capable of piercing the skin, the glucose sensor is inserted under the skin through the puncture assembly, and then the puncture assembly is removed from the skin and the glucose sensor remains under the skin.

[0004] In actual applications, the speed at which the puncture assembly is removed from the skin will affect the patient's comfort. Generally speaking, if the puncture assembly cannot be removed from the skin quickly, the patient's discomfort may increase. Summary of the invention

[0005] The utility model is completed in view of the above-mentioned prior art conditions, and its purpose is to provide a medical device application device that can quickly withdraw the puncture assembly and reduce the discomfort of the patient.

[0006] To this end, the utility model provides an application device, which is an application device for applying a medical device to the skin surface of a host, wherein the medical device includes a sensor inserted under the skin of the host and an electronic device electrically connected to the sensor and used to be applied to the skin of the host, the application device has a proximal end and a distal end and includes a first shell, a puncture assembly, a moving body connected to the medical device, and a first driving component arranged on the moving body; the first shell is configured to fit the skin of the host to trigger the moving body and the puncture assembly to move toward the distal end; the moving body and the puncture assembly are configured to: when the moving body and the puncture assembly are in a locked state, they move toward the distal end together; when the moving body and the puncture assembly are in a released state under the action of the first shell, the puncture assembly is moved toward the proximal end under the action of the first driving component; at least a portion of the sensor is arranged in the puncture assembly, and the puncture assembly is configured to provide an insertion path for the sensor to be inserted under the skin of the host.

[0007] In the utility model, the moving body carrying the medical device and the puncture assembly can be moved together from the distal end to the proximal end until the puncture assembly and the sensor are inserted under the skin. After the sensor is inserted under the skin, the puncture assembly can be quickly withdrawn from under the host's skin through the first driving component, thereby reducing the host's discomfort.

[0008] In addition, according to the application device involved in the utility model, optionally, the moving body includes a first opening and a second opening arranged opposite to each other, and when the puncture assembly is at the proximal end, the puncture assembly does not pass through the second opening. In this case, the first opening and the second opening can form a channel to provide a movement channel for the puncture assembly and the sensor to be inserted under the skin, and when the puncture assembly is at the proximal end, the puncture assembly does not pass through the second opening, thereby reducing the situation where the user is injured by the puncture assembly.

[0009] In addition, according to the application device of the utility model, optionally, the first driving component is an elastic element, one end of the first driving component abuts against the first end of the puncture assembly, and the other end of the first driving component abuts against the first surface of the moving body. Thus, the elastic element can easily realize the function of automatically withdrawing the puncture assembly from under the skin.

[0010] In addition, according to the application device involved in the utility model, optionally, when the moving body and the puncture assembly are in a locked state, the first driving component has elastic potential energy. In this case, when the position of the puncture assembly is not restricted by other components, the first driving component can release the elastic potential energy, thereby being able to drive the puncture assembly, thereby the first driving component can quickly withdraw the puncture assembly from under the skin.

[0011] In addition, the application device according to the utility model may optionally further include a first locking mechanism, and the moving body and the puncture assembly are detachably connected through the first locking mechanism. In this case, the moving body and the puncture assembly can be locked by the first locking mechanism, so that the moving body and the puncture assembly can move together from the proximal end to the distal end; when the first locking mechanism is in a released state, the moving body and the puncture assembly can be separated, so as to facilitate driving the puncture assembly to move from the distal end to the proximal end.

[0012] In addition, according to the application device involved in the utility model, optionally, the first locking mechanism includes a clamping portion provided on the puncture assembly and a first clamping groove provided on the moving body; the clamping portion of the puncture assembly can pivot and pivot in response to a force directed in a first direction, and is separated from the first clamping groove of the moving body, so that the first locking mechanism is in a released state. In this case, the structure of the first locking mechanism can be made simple, and the locked state can be formed more stably, and the locked state can also be released more easily.

[0013] In addition, according to the application device involved in the utility model, optionally, the moving body is sleeved in the hollow part of the first shell, and the first shell is provided with a protrusion, and when the puncture assembly is located at the distal end, the protrusion is configured to apply a force pointing to the first direction to the clamping part of the puncture assembly. In this case, when the puncture assembly moves from the proximal end to the distal end, the protrusion can conveniently change the moving body and the puncture assembly from a locked state to a released state. Thereby, the first locking mechanism can be unlocked, so that the puncture assembly can be separated from the moving body.

[0014] In addition, according to the application device involved in the utility model, optionally, the protrusion has a first guide surface, and the clamping part of the puncture assembly has a second guide surface. When the first locking mechanism changes from the locked state to the released state, the first guide surface and the second guide surface cooperate with each other to gradually separate the clamping part of the puncture assembly from the first clamping groove of the moving body. In this case, the first guide surface and the second guide surface can cooperate with each other to gradually unlock the first locking mechanism, so that the process of inserting the puncture assembly into the skin is a gradual process, thereby providing sufficient time for the puncture assembly to be inserted into the skin to a predetermined depth, and reducing the situation where the puncture assembly fails to fully insert into the skin to a predetermined depth.

[0015] In addition, according to the application device involved in the utility model, optionally, the moving body is provided with a limit block, and when the puncture assembly moves from the distal end to the proximal end, the limit block is used to limit the movement of the puncture assembly toward the proximal end. In this case, when the puncture assembly is withdrawn from the skin and moves from the distal end to the proximal end, the limit block can limit the moving distance of the puncture assembly, thereby reducing the situation where the puncture assembly impacts the application device.

[0016] In addition, according to the application device involved in the utility model, optionally, the moving body includes a main body having a first end, and when the puncture assembly is at the proximal end, the clamping part of the puncture assembly abuts against the first end of the main body. In this case, when the puncture assembly is at the proximal end, the puncture assembly can be restricted by the first end of the main body and can be more firmly restricted by the moving body at the proximal end, thereby reducing the situation where the puncture assembly moves toward the distal end, so as to reduce the situation where the puncture assembly accidentally hurts the user.

[0017] According to the utility model, a medical device application device can be provided which can quickly withdraw the puncture assembly and reduce the discomfort of the patient. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2A 1 is a schematic diagram showing the entirety of a medical device 20 according to an example of the present invention. Figure 2B 1 is a schematic diagram showing the entirety of the sensor 21 according to the example of the present invention.

Figure 3B It is a schematic diagram showing the structure of the applying device 10 involved in the example of the utility model after the cap 11 is removed.

[0040] For some examples, see Figure 1 The medical device 20 can be applied to a host to monitor the concentration value of an analyte in the host.

[0041] See also Figure 1 and Figure 2A In some examples, the medical device 20 may include a sensor 21 inserted under the skin of a host and an electronic device 22 electrically connected to the sensor 21 and adapted to be attached to the skin of the host.

[0042] In some examples, the electronic device 22 may obtain the concentration value of the analyte measured by the sensor 21 and transmit it to the control unit.

[0043] In some examples, the control unit may be a smart terminal, such as a smart mobile phone, a smart tablet computer, or a computer device. In some examples, the electronic device 22 may establish a communication connection with the control unit via a wireless link.

[0044] In some examples, the electronic device 22 may include an adhesive material for attaching the electronic device 22 to the surface of the skin.

[0045] See also Figure 2B In some examples, the sensor 21 may include a first portion 211 and a second portion 212 .

[0046] In some examples, the first portion 211 of the sensor 21 may include an in-vivo portion 2111 inserted under the skin of the host. In some examples, the second portion 212 of the sensor 21 may include an electrical contact portion 2121 electrically connected to the electronic device 22.

[0047] In some examples, the in vivo portion 2111 of the sensor 21 may include a sensing layer that can electrochemically react with the analyte to generate an electrical signal representative of the concentration value of the analyte.

[0048] See also Figure 3A In some examples, the application device 10 may include a cap 11. In some examples, the cap 11 may be connected to the operating portion of the application device 10 by threads.

[0049] In actual operation, after the cap 11 is removed, the application device 10 can be placed on the skin surface of the host to start the application action.

[0050] In some examples, the application device 10 may have a proximal end and a distal end. In some examples, the proximal end may refer to a position of the application device 10 that is far from the skin surface, and the distal end may refer to a position of the application device 10 that is close to the skin surface, such as at Figure 3A In the embodiment, the position of the cap 11 may be at the distal end.

[0051] Referring to section 3B, in some examples, the medical device 20 is detachably connected to the application device 10. In some examples, the application device 10 can apply the medical device 20 to the skin surface of the host. In some examples, the action of the application device 10 applying the medical device 20 to the skin surface of the host (which can be simply referred to as the application action) can also be referred to as the application device 10 delivering the medical device 20 to the skin surface of the host (which can be simply referred to as the delivery action).

[0052] In some examples, the application device 10 completing the application action can also be understood as the application device 10 transporting the medical device 20 from the proximal end of the application device 10 to the distal end of the application device 10 .

[0053] In some examples, after the application device 10 completes the application action, it can be separated from the medical device.

[0054] Figure 4A 1 is a schematic diagram showing a moving body 12 according to an example of the present invention. Figure 4B It is a schematic diagram showing another viewing direction of the moving body 12 involved in the example of the present utility model.

[0055] In some examples, the application device 10 may include a moving body 12, and the moving body 12 may be connected to the medical device 20. In some examples, the moving body 12 may be detachably connected to the medical device 20. In this case, the moving body 12 can deliver the medical device 20 to the host's skin, and after the electronic device 22 of the medical device 20 is attached to the host's skin surface, the moving body 12 can be separated from the medical device 20, that is, the application device 10 is separated from the medical device 20.

[0056] In some examples, the moving body 12 may include a first surface 121 (see Figure 4A ) and the second surface 122 (see Figure 4B ).

[0057] In some examples, the second surface 122 may be provided with a first space 1221 , and the moving body 12 may accommodate the medical device 20 . Thus, the medical device 20 may be placed in the first space 1221 and may be detachably connected to the moving body 12 .

[0058] In some examples, a clamping portion 12212 may be provided around the peripheral wall 12211 of the first space 1221 , and the clamping portion 12212 may be detachably connected to the medical device 20 .

[0059] In some examples, the size of the peripheral wall 12211 of the first space 1221 may match the outer peripheral size of the electronic device 22 so that the electronic device 22 can be stably assembled in the first space 1221 .

[0060] For some examples, see Figure 4A The moving body 12 may include a first opening 123 and a second opening 124 that are arranged opposite to each other. In this case, the first opening 123 and the second opening 124 can form a channel to provide a movement channel for the puncture assembly 13 and the sensor 21 to be inserted under the skin (described later).

[0061] In some examples, the moving body 12 may have a first axis X. In some examples, the first axis X may be a central axis of the moving body 12 .

Figure 5B 1 is a schematic diagram showing a support seat 131 according to an example of the present invention. Figure 5C It is a schematic diagram showing another viewing direction of the support seat 131 involved in the example of the present utility model. Figure 5D Schematic diagram showing the first locking mechanism 14 according to the example of the present invention.

[0063] In some examples, the application device 10 may include a puncture assembly 13. In this case, the sensor 21 can be inserted under the skin through the puncture assembly 13.

[0064] In some examples, at least a portion of the sensor 21 may be disposed in the puncture assembly 13, and the puncture assembly 13 may be configured to provide an insertion path for the sensor 21 to be inserted under the skin of the host. In this case, since the sensor 21 is generally a flexible material, by puncturing the skin using the puncture assembly 13, it is possible to facilitate the insertion of the sensor 21 under the skin of the host.

[0065] See also Figure 5A In some examples, the puncture assembly 13 may include a support seat 131 and a sharp body 132.

[0066] For some examples, see Figure 5A The sharp body 132 may include a holding portion 1321 and a sharp portion 1322. In some examples, the support seat 131 may be connected to the holding portion 1321.

[0067] For some examples, see Figure 5A The support seat 131 may have a hollow second space 1311 , and the retaining portion 1321 may be accommodated in the second space 1311 of the support seat 131 to form a fixed connection between the support seat 131 and the retaining portion 1321 .

[0068] For some examples, see Figure 5A The sharp portion 1322 may have an opening slot 13221 , and at least a portion of the sensor 21 may be disposed in the opening slot 13221 of the sharp portion 1322 . Specifically, the first portion 211 of the sensor 21 may be disposed in the opening slot 13221 .

[0069] In some examples, the application device 10 may include a first locking mechanism 14, and the moving body 12 and the puncture assembly 13 may be detachably connected via the first locking mechanism 14 (see Figure 5D In this case, the first locking mechanism 14 can lock the moving body 12 and the puncture assembly 13, so that the moving body 12 and the puncture assembly 13 can move together from the proximal end to the distal end; when the first locking mechanism 14 is in a released state, the moving body 12 and the puncture assembly 13 can be separated, so that it is easy to drive the puncture assembly 13 to move from the distal end to the proximal end.

[0070] In some examples, when the first locking mechanism 14 is in a locked state, the moving body 12 can be fixedly connected to the puncture assembly 13, and when the first locking mechanism 13 is in a released state (also referred to as an unlocked state), the moving body 12 can be separated from the puncture assembly 13. In this case, when the first locking mechanism 14 is in a locked state, during the process of inserting the sensor 21 under the skin of the host, the first locking mechanism 14 can keep the relative position of the puncture assembly 13 and the moving body 12 fixed, that is, the relative position of the puncture assembly 13 and the sensor 21 fixed, thereby facilitating the insertion of the sensor 21 under the skin; when the first locking mechanism 14 is in a released state, the moving body 12 and the puncture assembly 13 can be in a separated state, thereby facilitating the movement of the puncture assembly 13 alone.

[0071] In some examples, the first locking mechanism 14 may include a clamping portion 133 disposed on the puncture assembly 13 (see Figure 5B ) and the first slot 125 (see Figure 4A In this case, the engaging portion 133 of the puncture assembly 13 can abut against the first engaging groove 125 of the moving body 12, so that the first locking mechanism 14 is in a locked state, thereby being able to keep the relative positions of the puncture assembly 13 and the moving body 12 fixed.

[0072] In some examples, the clamping portion 133 of the puncture assembly 13 may be pivotable. Specifically, the clamping portion 133 of the puncture assembly 13 may be deflected by an external force.

[0073] For some examples, see Figure 5A , the puncture assembly 13 can have a second axis Y. In some examples, the second axis Y can be a central axis of the puncture assembly 13 .

[0074] In some examples, the engaging portion 133 of the puncture assembly 13 can pivot in response to a force directed in the first direction, and separate from the first engaging groove 125 of the moving body 12, so that the first locking mechanism 14 is in a released state. In this case, the structure of the first locking mechanism 14 can be made simple, and the locked state can be formed more stably, and the locked state can also be released more easily.

[0075] In some examples, the first direction may be a direction pointing to the second axis Y. In some examples, the first direction may be a direction perpendicular to the second axis Y (see Figure 5A In some examples, the first direction may also refer to a direction in which the clamping portion 133 of the puncture assembly 13 is deflected toward the second axis Y.

[0076] In some examples, the clamping portion 133 of the puncture assembly 13 may have an expanded state and a deflected state. Specifically, when the clamping portion 133 is not subjected to a force directed in the first direction, the clamping portion 133 may be in an expanded state, and when the clamping portion 133 is subjected to a force directed in the first direction, the clamping portion 133 may be in a deflected state.

[0077] In some examples, when the engaging portion 133 of the puncture assembly 13 is locked with the first engaging slot 125 of the moving body 12, the engaging portion 133 of the puncture assembly 13 may be in an expanded state and engaged in the first engaging slot 125 of the moving body 12 (see Figure 5D ).

[0078] In some examples, when the clamping portion 133 of the puncture assembly 13 is subjected to a force directed in the first direction, the clamping portion 133 of the puncture assembly 13 may be in a deflected state (also referred to as a pivoted state).

[0079] Fig. 6A 1 is a schematic diagram showing that the moving body 12 involved in the example of the present utility model is located at the proximal end. Fig. 6A In the figure, the first portion 211 of the sensor 21 is separated from the sharp portion 1322 in order to better display the first portion 211 of the sensor 21 in the figure. In actual applications, the first portion 211 of the sensor 21 can be located in the opening groove 13221 of the sharp portion 1322.

[0080] Fig. 6A It also shows the position states of the various components when the application device 10 has not yet started the conveying action. Figure 6B 1 is a schematic diagram showing the cooperation between the moving body 12 and the first shell 16 involved in the example of the utility model.

[0081] Figure 7 It is a schematic diagram showing that the puncture assembly 13 involved in the example of the utility model is in the second state. Figure 8 It is a schematic diagram showing that the puncture assembly 13 involved in the example of the utility model is in the third state.

[0082] In some examples, puncture assembly 13 may include a first state, a second state, and a third state.

[0083] In some examples, the puncture assembly 13 being in the first state can be understood as the puncture assembly 13 and the moving body 12 are connected via the first locking mechanism 14 (see Figure 5D and Fig. 6A ).

[0084] In addition, the puncture assembly 13 being in the second state can be understood as the first locking mechanism 14 being unlocked, the puncture assembly 13 being separated from the moving body 12, and the puncture assembly 13 being inserted under the skin of the host (see Figure 7 ).

[0085] In addition, the puncture assembly 13 being in the third state can be understood as the puncture assembly 13 being completely located inside the application device 10 (see Figure 8 ).

[0086] In the utility model, when the puncture assembly 13 is in the first state, the relative position of the puncture assembly 13 and the moving body 12 is fixed, which can facilitate the insertion of the puncture assembly 13 under the skin and can facilitate the insertion of the sensor 21 under the skin; when the puncture assembly 13 is in the second state, the puncture assembly 13 and the moving body 12 are in a separated state, and the puncture assembly 13 can be taken out from under the skin without affecting the moving body 12. Therefore, in the process of retrieving the puncture assembly 13, the moving body 12 can simultaneously press the electronic device 22 to the skin surface, so that the process of retrieving the puncture assembly 13 does not affect the application of the electronic device 22 to the skin surface; when the puncture assembly 13 is in the third state, the application device 10 has completed the conveying action of the medical device 20, and there is a possibility that the application device 10 will be abandoned. By completely covering the puncture assembly 13 with the application device 10, the possibility of the user being harmed by the puncture assembly 13 can be reduced.

[0087] In some examples, when the puncture assembly 13 is in the first state and the second state, at least a portion of the puncture assembly 13 and at least a portion of the sensor 21 can pass through the second opening 124 of the moving body 12 (see Figure 4A and Figure 5D ). Thus, the puncture assembly 13 and the sensor 21 can be inserted under the skin of the host.

[0088] In some examples, the first axis X and the second axis Y may coincide. In some examples, the central axes of the moving body 12 and the puncture assembly 13 may coincide.

[0089] In the present invention, the application device 10 can deliver the medical device 20 to the host's skin, so that the sensor 21 of the medical device 20 is inserted under the skin, and the electronic device 22 is attached to the host's skin. Fig. 6A , Figure 6B and Figure 7 Describe this.

[0090] In some examples, the moving body 12 and the puncture assembly 13 can be configured to move toward the distal end together when the moving body 12 and the puncture assembly 13 are in a locked state. In this case, the medical device 20 can be moved from the proximal end to the distal end for application to the skin surface.

[0091] In some examples, the application device 10 can be configured to move the moving body 12 provided with the medical device 20 and the puncture assembly 13 in the first state from the proximal end to the distal end, and the puncture assembly 13 can be changed from the first state to the second state (see Fig. 6A and Figure 7 ).

[0092] See also Fig. 6AIn some examples, the applying device 10 may include a second shell 15. In some examples, the applying device 10 may include a first shell 16. In some examples, the first shell 16 may be sleeved in the hollow portion of the second shell 15, and the first shell 16 and the second shell 15 may move relative to each other.

[0093] In some examples, the second end 161 of the first housing 16 can abut against the host's skin.

[0094] In some examples, the first housing 16 may be configured to fit against the host's skin to trigger the moving body 12 and the puncture assembly 13 to move distally.

[0095] See also Fig. 6A In some examples, the applying device 10 may include a second locking mechanism 17. In this case, the second locking mechanism 17 can make the relative position between the second housing 15 and the moving body 12 have two states: locked and unlocked.

[0096] In some examples, the moving body 12 and the second shell 15 can be detachably connected via a second locking mechanism 17. When the second locking mechanism 17 is in a locked state, the moving body 12 can be fixedly connected to the second shell 15. When the second locking mechanism 17 is in a released state (also referred to as an unlocked state), the moving body 12 can be separated from the second shell 15.

[0097] In some examples, when the moving body 12 is at the proximal end, the second housing 15 and the moving body 12 may be fixedly connected via the second locking mechanism 17. Thus, the applying device 10 may be in a state where the applying action is not started or is to be started.

[0098] In some examples, the second locking mechanism 17 may include a first clamping portion 151 disposed on the second housing 15 (see Fig. 6A ) and a second slot 126 (see Figure 4A and Fig. 6A ), the second card slot 126 of the moving body 12 can be pivoted and, in response to a force directed in the second direction, separated from the first card portion 151 of the second shell 15, so that the second locking mechanism 17 is in a released state.

[0099] In some examples, the second direction may be a direction pointing to the first axis X. In some examples, the second direction may be a direction perpendicular to the first axis X (see Fig. 6A In some examples, the second direction may also refer to a direction in which the second slot 126 of the moving body 12 is deflected toward the first axis X.

[0100] In some examples, the second direction and the first direction can be the same.

[0101] See also Fig. 6A In some examples, the first shell 16 can move toward the first end 152 of the second shell 15 relative to the second shell 15, and the first end 162 of the first shell 16 can apply a force pointing to the second direction to the second slot 126 of the moving body 12.

[0102] Specifically, the application device 10 can be placed on the skin surface of the host, and the second end 161 of the first shell 16 can be against the skin surface. At this time, a force toward the skin can be applied to the second shell 15, so that the first shell 16 moves relative to the second shell 15 toward the first end 152 of the second shell 15, and the first end 162 of the first shell 16 can apply a force pointing to the second direction (for example, Fig. 6A In this case, the second locking mechanism 17 can be unlocked to separate the moving body 12 from the first housing 16, thereby facilitating the moving body 12 and the puncture assembly 13 to move toward the distal end together.

[0103] For some examples, see Fig. 6A , the application device 10 may include a driving component 18. In this case, the application device 10 can automatically complete the application action and the action of withdrawing the puncture assembly 13 from under the skin through the driving component 18.

[0104] For some examples, see Fig. 6A , the driving component 18 may include a second driving component 182. In this case, the second driving component 182 can drive the moving body 12 to drive the puncture assembly 13 to move from the proximal end to the distal end.

[0105] In some examples, the second driving component 182 is an elastic element, one end of the second driving component 182 can abut against the first end 152 of the second shell 15, and the other end of the second driving component 182 can abut against the first surface 121 of the moving body 12 (see Figure 6B ) abutment.

[0106] In some examples, the second drive member 182 may be a spring.

[0107] In some examples, the second driving component 182 may also abut against a rib disposed on the moving body 12 (see Figure 6B ).

[0108] In some examples, when the moving body 12 is at the proximal end, the second driving component 182 may have elastic potential energy. In this case, when the position of the moving body 12 is not restricted by other components (such as the second locking mechanism 17), that is, when the moving body 12 can move from the proximal end to the distal end, the second driving component 182 can release the elastic potential energy, thereby being able to drive the moving body 12.

[0109] In some examples, the second driving component 182 may be a spring, and when the moving body 12 is at the proximal end, the second driving component 182 may be in a compressed state.

[0110] In the present invention, after the application device 10 delivers the medical device 20 to the host's skin, the application device 10 can move the puncture assembly 13 to the inside of the application device 10. Fig. 6A , Figure 6B , Figure 7 and Figure 8 Describe this.

[0111] See also Figure 6B and Figure 7 In some examples, the moving body 12 can be sleeved in the hollow portion of the first shell 16. In this case, it is advantageous for the moving body 12 to move relative to the first shell 16.

[0112] In some examples, the first housing 16 may be provided with a protrusion 163 (see Figure 7 ), when the puncture assembly 13 is at the distal end, the protrusion 163 can be configured to exert a force pointing in the first direction (for example Figure 7 In this case, when the puncture assembly 13 moves from the proximal end to the distal end, the protrusion 163 can easily change the moving body 12 and the puncture assembly 13 from the locked state to the released state (that is, the puncture assembly 13 changes from the first state to the second state). In this way, the first locking mechanism 14 (see Figure 5D ) is unlocked so that the puncture assembly 13 can be separated from the moving body 12.

[0113] See also Figure 7 and Figure 8 In some examples, the protrusion 163 may have a first guide surface 1631. In some examples, the clamping portion 133 of the puncture assembly 13 may have a second guide surface 1331 (see Figure 5B , Figure 5C and Figure 7 ).

[0114] In some examples, when the first locking mechanism 14 changes from a locked state to a released state (i.e., when the puncture assembly 13 changes from a first state to a second state), the first guide surface 1631 and the second guide surface 1331 cooperate with each other to gradually separate the clamping portion 133 of the puncture assembly 13 from the first clamping groove 125 of the moving body 12.

[0115] See also Figure 7 When the puncture assembly 13 changes from the first state to the second state, the first guide surface 1631 and the second guide surface 1331 cooperate with each other, so that the deflection state of the clamping portion 133 of the puncture assembly 13 gradually increases from small to large when the clamping portion 133 of the puncture assembly 13 pivots, until it is aligned with the first clamping groove 125 of the moving body 12 (see Figure 5D Specifically, along the path direction of the puncture assembly 13 moving from the proximal end to the distal end, the first guide surface 1631 and the second guide surface 1331 gradually shrink toward the second axis Y of the puncture assembly 13, that is, along Figure 7 In this case, the first guide surface 1631 and the second guide surface 1331 can cooperate with each other to gradually unlock the first locking mechanism 14, so that the process of inserting the puncture assembly 13 into the skin is a gradual process, thereby providing sufficient time for the puncture assembly 13 to be inserted into the skin to a predetermined depth, and reducing the situation where the puncture assembly 13 fails to be fully inserted into the skin to a predetermined depth.

[0116] See also Figure 7 In some examples, the driving component 18 may include a first driving component 181. In this case, the puncture assembly 13 can be driven to move to the inside of the application device 10 by the first driving component 181.

[0117] In some examples, the first driving component 181 may be disposed on the moving body.

[0118] In some examples, the moving body 12 and the puncture assembly 13 may be configured such that when the moving body 12 and the puncture assembly 13 are in a released state under the action of the first shell 16 , the puncture assembly 13 moves toward the proximal end under the action of the first driving component 181 .

[0119] In some examples, the first driving component 181 can drive the puncture assembly 13 to move from the distal end to the proximal end to the third state.

[0120] See also Figure 7 In some examples, the first driving component 181 may be an elastic element, one end of the first driving component 181 may abut against the first end 134 of the puncture assembly 13, and the other end of the first driving component 181 may abut against the first surface 121 of the moving body 12 (see Figure 4AThus, the elastic element can easily realize the function of automatically withdrawing the puncture assembly from under the skin.

[0121] In some examples, the first driving member 181 may be a spring.

[0122] In some examples, when the moving body 12 and the puncture assembly 13 are in a locked state, the first driving component 181 may have elastic potential energy. In this case, when the position of the puncture assembly 13 is not restricted by other components, the first driving component 181 can release the elastic potential energy, thereby driving the puncture assembly 13, thereby the first driving component 181 can quickly withdraw the puncture assembly 13 from under the skin.

[0123] In some examples, when the puncture assembly 13 is in the second state, the first driving component 181 may have elastic potential energy.

[0124] In some examples, the first driving component 181 may be a spring, and when the puncture assembly 13 is in the second state, the first driving component 181 may be in a compressed state.

[0125] See also Figure 8 In some examples, the moving body 12 may be provided with a limit block 127. When the puncture assembly 13 moves from the distal end to the proximal end, the limit block 127 may be used to limit the movement of the puncture assembly 13 toward the proximal end. Thus, when the puncture assembly 13 moves from the distal end to the proximal end (that is, the puncture assembly 13 withdraws from the skin), the limit block 127 can limit the moving distance of the puncture assembly 13, thereby reducing the situation where the puncture assembly 13 impacts other components.

[0126] See also Figure 8 In some examples, when the puncture assembly 13 is in the third state, the clamping portion 133 of the puncture assembly 13 may be in an expanded state.

[0127] See also Figure 8 In some examples, the moving body 12 may include a main body 128, and when the puncture assembly 13 is at the proximal end, the clamping portion 133 of the puncture assembly 13 may be clamped with the first end 1281 of the main body 128. In this case, when the puncture assembly 13 is at the proximal end, the puncture assembly 13 can be restricted by the first end 1281 of the main body 128, and can be more firmly restricted by the moving body 12 at the proximal end, thereby reducing the situation where the puncture assembly 13 moves toward the distal end, so as to reduce the situation where the puncture assembly 13 accidentally hurts the user.

[0128] In some examples, when the puncture assembly 13 is in the third state, the first driving component 181 may be in a compressed state. In other words, after the first driving component 181 moves the puncture assembly 13 from the distal end to the proximal end, the first driving component 181 still has an expansion force acting on the puncture assembly 13. Thus, the puncture assembly 13 can be more firmly held at the proximal end.

[0129] See also Figure 8 In some examples, when the puncture assembly 13 is at the proximal end, the puncture assembly 13 does not pass through the second opening 124 of the moving body 12. Thus, when the puncture assembly 13 is at the proximal end, the puncture assembly 13 does not pass through the second opening 124, thereby reducing the situation where the user is harmed by the puncture assembly 13.

[0130] See also Figure 7 and Figure 8 In some examples, the application device 10 may include a third locking mechanism 19. In this case, the third locking mechanism 19 can lock the first housing 16 with the second housing 15 to limit the movement of the first housing 16 relative to the second housing 15.

[0131] In some examples, the first housing 16 and the second housing 15 may be connected via a third locking mechanism 19. Figure 8 When the first housing 16 moves toward the first end 152 of the second housing 15 to unlock the first locking mechanism 14, the third locking mechanism 19 can lock the first housing 16 with the second housing 15. Thus, after the application device 10 completes the conveying action, the first housing 16 can no longer move relative to the second housing 15, thereby preventing the application device 10 from being reused unreasonably.

[0132] In some examples, the third locking mechanism 19 may include a second clamping portion 153 disposed on the second housing 15 and a clamping slot 164 disposed on the first housing 16 (see Figure 6B In this case, when the first housing 16 moves toward the first end 152 of the second housing 15 to unlock the first locking mechanism 14, the slot 164 of the first housing 16 can be combined with the second clamping portion 153 of the second housing 15 to lock the positional relationship between the first housing 16 and the second housing 15.

[0133] The utility model can provide an application device 10, which is an application device 10 for applying a medical device 20 to the skin surface of a host. The medical device 20 may include a sensor 21 inserted under the skin of the host and an electronic device 22 electrically connected to the sensor 21 and used to be attached to the skin of the host. The application device 10 may have a proximal end and a distal end and include a first shell 16, a puncture assembly 13, a moving body 12 connected to the medical device 20, and a first driving component 181 arranged on the moving body 12; the first shell 16 may be configured to fit the host's The skin is used to trigger the moving body 12 and the puncture assembly 13 to move distally; the moving body 12 and the puncture assembly 13 can be configured as follows: when the moving body 12 and the puncture assembly 13 are in a locked state, they move toward the distal end together; when the moving body 12 and the puncture assembly 13 are in a released state under the action of the first shell 16, the puncture assembly 13 moves toward the proximal end under the action of the first driving component 181; at least a portion of the sensor 21 can be arranged in the puncture assembly 13, and the puncture assembly 13 can be configured to provide an insertion path for the sensor 21 to be inserted under the skin of the host.

[0134] In the utility model, the moving body 12 carrying the medical device 20 and the puncture assembly 13 can be moved together from the distal end to the proximal end of the application device 10 until the puncture assembly 13 and the sensor 21 are inserted under the skin, and after the sensor 12 is inserted under the skin, the puncture assembly 13 can be quickly withdrawn from under the host's skin through the first driving component 181, thereby reducing the host's discomfort.

[0135] Although the utility model is specifically described above in conjunction with the accompanying drawings and embodiments, it is to be understood that the above description does not limit the utility model in any form. Those skilled in the art can modify and change the utility model as needed without departing from the essential spirit and scope of the utility model, and these modifications and changes all fall within the scope of the utility model.
