Description

Integral press trigger application device Technical Field

[0001] The utility model relates to the field of biomedical engineering industry, and in particular to an integral press-trigger application device. Background Art

[0002] For diabetic patients, real-time and continuous monitoring of glucose concentrations in body fluids is essential on a daily basis. This allows patients to adjust glucose concentrations in a timely manner, such as through dietary adjustments or medication, thereby reducing the occurrence of complications caused by abnormal glucose concentrations. Traditional methods of monitoring glucose concentrations in body fluids require users to repeatedly draw blood from their fingertips, which is not only troublesome but also causes great pain to the patient. CGM (Continuous Glucose Monitoring) is a device that can be used to dynamically monitor the body's glucose concentration, eliminating the need for repeated fingertip blood sampling.

[0003] Before a CGM can function properly, it must be applied to the skin. Currently, this involves using a specialized applicator to pick up the CGM and pressing a button on the device's housing to apply the CGM to the skin, enabling continuous, dynamic monitoring of glucose concentrations in bodily fluids.

[0004] However, in the prior art, the application device always triggers the action of applying the CGM to the skin surface of the human body by pressing a button. Since the force application area of ​​the button is small, the triggering method of the application device is still not convenient enough. Summary of the Invention

[0005] The present invention is proposed in view of the above situation, and its purpose is to provide an integral press-trigger type applying device that can improve the convenience of the triggering mode.

[0006] To this end, the utility model provides an integral press-trigger application device, which is an application device for applying a medical device to a host. The application device includes a first shell, a second shell, a movable component, and a proximal end close to the host and a distal end away from the host during operation. The first shell is assembled with the second shell and the movable component is assembled with the second shell. The movable component can move from the distal end toward the proximal end relative to the second shell. The movable component includes a accommodating portion for accommodating the medical device, a retaining mechanism that can be releasably retained in the first shell and the second shell, and a guide member for guiding the medical device for application. When the first shell moves from the distal end toward the proximal end relative to the second shell, the first shell and the second shell release the retaining mechanism.

[0007] In the present invention, the first shell and the second shell can release the retaining mechanism by moving the first shell from the distal end toward the proximal end relative to the second shell. In other words, by pressing the first shell, the movable component can be moved from the distal end toward the proximal end relative to the second shell to guide the medical device to be applied to the host, thereby improving the convenience of the triggering method.

[0008] In addition, in the integral press-trigger application device of the present invention, the application device may optionally further include a first drive mechanism disposed between the first housing and the movable assembly, the first drive mechanism applying a force toward the proximal end to the movable assembly. In this case, when the first housing and the second housing release the retaining mechanism, the force applied by the first drive mechanism to the movable assembly can drive the movable assembly toward the proximal end, thereby improving the convenience of the movable assembly in driving the medical device toward the proximal end.

[0009] In addition, in the integrated push-trigger application device of the present invention, optionally, a first limiting mechanism is formed on the first housing, and a fitting portion is formed on the second housing that slidably engages with the first limiting mechanism. This can improve the convenience of moving the first housing from the distal end to the proximal end relative to the second housing.

[0010] In addition, in the integrated push-trigger application device of the present invention, optionally, the retaining mechanism includes a first retaining portion, a second limiting mechanism is formed on the first housing, and the first retaining portion is releasably retained by the second limiting mechanism. Thus, the retaining mechanism can be releasably retained on the first housing.

[0011] In addition, in the integral press-trigger application device involved in the present invention, optionally, the retaining mechanism includes a first retaining arm that gradually expands in the direction from the proximal end to the distal end and a second retaining portion that is releasably retained on the second shell, and the second retaining portion and the first retaining portion are sequentially formed on the first retaining arm in the direction from the proximal end to the distal end. In this case, when the second retaining portion is offset toward the central axis of the movable component (for example, when the second retaining portion is subjected to a force acting toward the central axis of the movable component), the offset second retaining portion can cause the first retaining arm to deflect toward the central axis of the movable component, so that the deflected first retaining arm can drive the first retaining portion to deflect toward the central axis of the movable component, thereby enabling the second limiting mechanism to release the first retaining portion, thereby improving the convenience of releasing the movable component between the first shell and the second shell.

[0012] In addition, in the integrated push-trigger application device of the present invention, the second housing optionally includes a third limiting mechanism that abuts the second retaining portion. When the first retaining portion is released from the first housing, the first retaining portion abuts the third limiting mechanism. This reduces the risk of the released movable component detaching from the second housing.

[0013] In addition, in the integrated push-trigger application device of the present invention, optionally, the movable assembly comprises a first bottom portion proximal to the distal end, a second bottom portion proximal to the proximal end, and a sidewall connecting the first bottom portion and the second bottom portion, and the first driving mechanism is disposed between the first housing and the first bottom portion. Thus, the first driving mechanism can act on the movable assembly by acting on the first bottom portion, thereby improving the structural compactness of the movable assembly.

[0014] In addition, in the integrated push-trigger application device of the present invention, optionally, the movable assembly includes an opening near the distal end, a second bottom near the proximal end, and a sidewall connecting the opening and the second bottom, the sidewall including an extension extending along the central axis of the movable assembly toward the periphery of the movable assembly, and the first driving mechanism is disposed between the first housing and the extension. Thus, the first driving mechanism can act on the movable assembly by acting on the extension, thereby improving the structural flexibility of the movable assembly.

[0015] In addition, in the integrated push-trigger application device of the present invention, the guide member can optionally be releasably retained by the side wall, and a second drive mechanism is provided between the guide member and the second bottom portion, the second drive mechanism applying a force to the guide member toward the distal end. In this case, when the guide member is no longer retained by the side wall, the force applied by the second drive mechanism to the guide member can drive the guide member toward the distal end, thereby facilitating the decoupling of the guide member and the medical device after the guide member guides the medical device to be applied to the host, thereby improving the ease of operation of the application device.

[0016] In addition, in the integral press-trigger application device of the present invention, optionally, the guide member includes a second retaining arm releasably retained on the side wall, the second retaining arm gradually expanding in a direction from the proximal end toward the distal end, the second retaining arm abutting against the side wall, and a trigger mechanism is formed in the second shell, and during the movement of the movable component toward the proximal end, the trigger mechanism acts on the second retaining arm. In this case, the trigger mechanism acting on the second retaining arm can deflect the second retaining arm toward the central axis of the movable component, thereby canceling the abutment between the second retaining arm and the side wall, thereby enabling the guide member to move toward the distal end under the action of the second drive mechanism, thereby improving the convenience of decoupling the guide member from the medical device.

[0017] According to the utility model, an integral press-trigger type applying device can be provided which improves the convenience of the triggering mode. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. In the following description, identical components will be assigned identical reference numerals, and duplicate descriptions will be omitted. In addition, the accompanying drawings are merely schematic, and the proportions of the dimensions of the components or the shapes of the components may differ from the actual ones.

[0028] It should be noted that the terms "include" and "have" and any variations thereof in the present invention, such as a process, method, system, product or device that includes or has a series of steps or units, are not necessarily limited to those steps or units clearly listed, but may include or have other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0029] The present invention provides an integral press-trigger application device, which is an application device for applying a medical device to a host (hereinafter referred to as an application device). In some examples, the medical device may be a continuous glucose monitor (CGM), and the host may be a human body. The application device involved in the present invention can improve the convenience of the triggering method. In the present invention, the triggering method may refer to the action of triggering the application device to apply (or apply) the medical device to the skin surface of the host.

[0030] Hereinafter, the applying device of the present invention will be described by taking a continuous glucose monitor as an example of a medical device.

[0031] FIG1 is a schematic diagram showing the combination of an application device 10 and a cartridge device 20 according to an example of the present invention. FIG2 is a schematic diagram showing the separation of the application device 10 and the cartridge device 20 according to an example of the present invention. FIG3 is an exploded schematic diagram showing the application device 10 and the cartridge device 20 according to an example of the present invention.

[0032] In some examples, the application device 10 can be combined with the cartridge device 20 (see FIG1 ). In some examples, the application device 10 can be combined with the cartridge device 20 in a screw manner. For example, the application device 10 and the cartridge device 20 can each have corresponding threads, and the application device 10 can be screwed into the cartridge device 20 via the threads.

[0033] In some examples, the application device 10 can be separated from the cartridge device 20 (see FIG. 2 ). In some examples, the application device 10 can be separated from the cartridge device 20 in a spiral manner. For example, the application device 10 and the cartridge device 20 can each have corresponding threads, and the application device 10 can be screwed out of the cartridge device 20 through the threads.

[0034] In some examples, the cartridge device 20 can accommodate a medical device 30. In some examples, after the cartridge device 20 is combined with the application device 10, the application device 10 can pick up the medical device 30.

[0035] In some examples, the application device 10 may include a proximal end that is closer to the host during operation and a distal end that is farther away from the host. In other words, in the present invention, "proximal end" can be understood as the end of the application device 10 that is closer to the host during operation, "distal end" can be understood as the end of the application device 10 that is farther away from the host during operation, and "operation" can be understood as the operation of applying the medical device 30 to the host through the application device 10.

[0036] In some examples, the application device 10 may include a first housing 110 and a second housing 120 (see FIG3 ). The first housing 110 may be assembled with the second housing 120. In some examples, the first housing 110 may be assembled with the second housing 120 by engaging an inner wall of the first housing 110 with an outer periphery of the second housing 120.

[0037] In some examples, the first housing 110 can be moved from the distal end to the proximal end relative to the second housing 120. In the present invention, the operation of applying the medical device 30 to the host by the application device 10 can refer to the operation of moving the first housing 110 from the distal end to the proximal end relative to the second housing 120 after the application device 10 picks up the medical device 30.

[0038] In some examples, after the first housing 110 and the second housing 120 are assembled, the second housing 120 may protrude proximally from the first housing 110. In some examples, a space may be formed inside the application device 10 for the first housing 110 to move from the distal end to the proximal end relative to the second housing 120.

[0039] Figure 4 is a schematic diagram illustrating a combination of a first housing 110 and a second housing 120 according to an example of the present invention. Figure 5 is a cross-sectional view taken along section line AA' in Figure 4 according to an example of the present invention. The dashed line CA in Figure 5 schematically illustrates the central axis of the first housing 110 or the second housing 120.

[0040] 5 , in some examples, a first limiting mechanism 1110 may be formed on the first housing 110. In some examples, a fitting portion 1210 may be formed on the second housing 120 to slidably engage with the first limiting mechanism 1110. This improves the ease with which the first housing 110 can be moved relative to the second housing 120 from the distal end to the proximal end.

[0041] In some examples, the first limiting mechanism 1110 may be formed on an inner wall of the first housing 110 , and the fitting portion 1210 may be formed on an outer periphery of the second housing 120 .

[0042] In some examples, the first limiting mechanism 1110 may include a first inclined surface that gradually approaches the central axis of the first housing 110 in a direction from the proximal end to the distal end. In some examples, the assembly portion 1210 may include a second inclined surface that gradually approaches the central axis of the second housing 120 in a direction from the proximal end to the distal end. The first inclined surface and the second inclined surface may match each other. This improves the ease of operation for moving the first housing 110 from the distal end to the proximal end relative to the second housing 120.

[0043] In the present invention, the first inclined surface and the second inclined surface matching each other may refer to the first inclined surface and the second inclined surface being in contact with each other.

[0044] In some examples, the first limiting mechanism 1110 may include a first plane extending along the inner wall of the first shell 110 toward the central axis of the first shell 110. The first plane may be closer to the distal end than the first inclined surface. In some examples, the assembly portion 1210 may include a second plane extending along the central axis of the second shell 120 toward the outer periphery of the second shell 120. The second plane may be closer to the proximal end than the second inclined surface. In some examples, the first plane and the second plane may match. In this case, when the first shell 110 is moved from the distal end to the proximal end relative to the second shell 120, the first inclined surface of the first limiting mechanism 1110 can be matched with the second inclined surface of the assembly portion 1210, and the first plane of the first limiting mechanism 1110 can be matched with the second plane of the assembly portion 1210. This can reduce the possibility that the second shell 120 and the first shell 110 will return to the state where the first inclined surface matches the second inclined surface, so as to reuse the application device 10.

[0045] In the present invention, matching the first plane with the second plane may mean that the first plane and the second plane are in contact with each other.

[0046] In some examples, there may be two first limiting mechanisms 1110. The two first limiting mechanisms 1110 may be located on the same side of the central axis of the first housing 110. In some examples, the assembly portion 1210 may be disposed between the two first limiting mechanisms 1110. This improves the stability of the assembly between the first housing 110 and the second housing 120.

[0047] In some examples, there may be four first limiting mechanisms 1110 , and the four first limiting mechanisms 1110 may be located in pairs on both sides of the central axis of the first housing 110 .

[0048] In some examples, the application device 10 may include a movable assembly 130 (see FIG. 3 ). The movable assembly 130 may be assembled with the second housing 120. In some examples, the movable assembly 130 may be assembled with the second housing 120 by having the outer periphery of the movable assembly 130 abut against the inner wall of the second housing 120.

[0049] In some examples, the movable assembly 130 can move from the distal end to the proximal end relative to the second housing 120 .

[0050] In some examples, the movable assembly 130 may be at least partially disposed between the first housing 110 and the second housing 120. In this way, the structural compactness of the application device 10 can be improved.

[0051] In some examples, when the first housing 110 moves from the distal end to the proximal end relative to the second housing 120 , the movable assembly 130 may be configured to be movable toward the proximal end.

[0052] FIG6 is an exploded schematic diagram illustrating the movable assembly 130 according to an example of the present invention. FIG7 is a cross-sectional view illustrating the application device 10 according to an example of the present invention, taken along a vertical line perpendicular to the section line AA′ in FIG4 . In order to better illustrate the engagement between the retaining mechanism 1320 and the first and second housings 110 and 120, some components or lines that may affect the description are omitted and simplified in FIG7 .

[0053] In some examples, the movable assembly 130 may include a receiving portion 1310 (see FIG. 6 ) for receiving the medical device 30. The receiving portion 1310 may have a receiving space that matches the outer contour of the medical device 30. In this case, when the movable assembly 130 moves toward the proximal end, it can drive the medical device 30 toward the proximal end, thereby improving the ease of applying the medical device 30 to the host.

[0054] In some examples, the movable assembly 130 may include a retaining mechanism 1320 (see Figures 6 and 7) that is releasably retained by the first housing 110 and the second housing 120. In other words, the movable assembly 130 may be configured to be retained by the first housing 110 and the second housing 120 under the cooperation of the retaining mechanism 1320 and the first housing 110 and the second housing 120.

[0055] In some examples, when the first shell 110 moves from the distal end toward the proximal end relative to the second shell 120, the retaining mechanism 1320 can be released from the first shell 110 and the second shell 120 to configure the movable component 130 to be movable toward the proximal end.

[0056] In some examples, the application device 10 may further include a first drive mechanism 140 (see FIG3 ). The first drive mechanism 140 may be disposed between the first housing 110 and the movable assembly 130. In some examples, the first drive mechanism 140 may apply a proximal force to the movable assembly 130. In this case, when the first housing 110 and the second housing 120 release the retaining mechanism 1320, the force applied by the first drive mechanism 140 to the movable assembly 130 may drive the movable assembly 130 toward the proximal end, thereby improving the convenience of the movable assembly 130 in driving the medical device 30 toward the proximal end.

[0057] In some examples, the first driving mechanism 140 may be a spring in a compressed state. In other examples, the first driving mechanism 140 may also be a spring in a stretched state.

[0058] In some examples, the retaining mechanism 1320 may include a first retaining portion 1321 (see Figures 6 and 7). In some examples, a second limiting mechanism 1120 (see Figure 7) may be formed on the first housing 110. The first retaining portion 1321 may be releasably retained by the second limiting mechanism 1120. Thus, the retaining mechanism 1320 can be releasably retained on the first housing 110.

[0059] In some examples, when the first shell 110 moves from the distal end toward the proximal end relative to the second shell 120 , the first shell 110 and the second shell 120 may release the retaining mechanism 1320 .

[0060] In some examples, the first retaining portion 1321 may include a first retaining surface extending along the central axis of the movable assembly 130 toward the periphery of the movable assembly 130 (see FIG7 ). In some examples, the second limiting mechanism 1120 may include a second retaining surface extending from the inner wall of the first shell 110 toward the central axis of the first shell 110. In some examples, when the first retaining portion 1321 is releasably retained in the first shell 110, the first retaining surface may abut against the second retaining surface. As a result, the stability of the first retaining portion 1321 when retained in the second limiting mechanism 1120 can be improved.

[0061] In some examples, the retaining mechanism 1320 can include a second retaining portion 1322 (see FIG. 6 and FIG. 7 ) that can be releasably retained by the second housing 120 . In other words, the second retaining portion 1322 can be releasably retained by the second housing 120 .

[0062] In some examples, when the first shell 110 moves from the distal end toward the proximal end relative to the second shell 120 , the second shell 120 may release the second retaining portion 1322 .

[0063] In some examples, second retaining portion 1322 may include a second inclined surface that gradually moves away from the central axis of movable assembly 130 in a proximal-to-distal direction. In some examples, the second inclined surface may abut against second housing 120. In this case, when the movable assembly 130 is acted upon proximally, the second inclined surface may gradually lose contact with second housing 120, thereby enabling second housing 120 to release second retaining portion 1322.

[0064] In some examples, the retaining mechanism 1320 may include a first retaining arm 1323 that gradually expands in a proximal-to-distal direction (see Figures 6 and 7). The second retaining portion 1322 and the first retaining portion 1321 may be sequentially formed on the first retaining arm 1323 in a proximal-to-distal direction. In this case, when the second retaining portion 1322 is offset toward the central axis of the movable component 130 (for example, when the second retaining portion 1322 is subjected to a force acting toward the central axis of the movable component 130), the offset second retaining portion 1322 can cause the first retaining arm 1323 to deflect toward the central axis of the movable component 130, thereby causing the deflected first retaining arm 1323 to drive the first retaining portion 1321 to deflect toward the central axis of the movable component 130, thereby causing the second limiting mechanism 1120 to release the first retaining portion 1321, thereby improving the convenience of releasing the retaining mechanism 1320 from the first shell 110 and the second shell 120.

[0065] In some examples, the first retaining arm 1323 may be formed on the outer periphery of the movable assembly 130 .

[0066] In some examples, the second housing 120 may include a third limiting mechanism 1220 (see FIG. 3 or FIG. 7 ) that abuts the second retaining portion 1322. Specifically, when the second retaining portion 1322 is releasably retained in the second housing 120, the second retaining portion 1322 may abut against the third limiting mechanism 1220.

[0067] In some examples, after the first retaining portion 1321 is released from the first housing 110 , the first retaining portion 1321 may abut against the third limiting mechanism 1220 , thereby reducing the risk of the released movable assembly 130 being separated from the second housing 120 .

[0068] In some examples, the third limiting mechanism 1220 can include a limiting notch 1221 that is recessed in a direction from the distal end toward the proximal end (see Figure 3 or Figure 7). In some examples, when the first retaining portion 1321 is released from the first housing 110, the first retaining surface can abut against the limiting notch 1221.

[0069] In some examples, the movable assembly 130 may have a first bottom portion 1330 near the distal end (see FIG. 3 or FIG. 6 ). In some examples, the first driving mechanism 140 may be disposed between the first housing 110 and the first bottom portion 1330 . Thus, the first driving mechanism 140 can act on the movable assembly 130 by acting on the first bottom portion 1330 .

[0070] In some examples, the movable component 130 may have an opening near the distal end. Specifically, the movable component 130 may not include the first bottom 1330 , and the end of the movable component 130 near the distal end may be set as an opening.

[0071] In some examples, the movable component 130 may have a second bottom portion 1340 near the proximal end (see FIG. 3 or FIG. 6 ). The second bottom portion 1340 may be connected to the upper surface of the receiving portion 1310 .

[0072] In some examples, the movable assembly 130 may include a side wall 1350 (see FIG. 3 or FIG. 6 ) connecting the first bottom portion 1330 and the second bottom portion 1340 . This improves the structural compactness of the movable assembly 130 .

[0073] In some examples, the sidewall 1350 can connect the opening and the second bottom 1340 , thereby improving the structural flexibility of the movable assembly 130 .

[0074] In some examples, the sidewall 1350 may include an extension extending along the central axis of the movable assembly 130 toward the periphery of the movable assembly 130. In some examples, the first driving mechanism 140 may be disposed between the first housing 110 and the extension. Thus, the first driving mechanism 140 can act on the movable assembly 130 by acting on the extension.

[0075] In some examples, the movable assembly 130 may include a guide member 1360 (see FIG. 3 or FIG. 6 ) for guiding the application of the medical device 30. Specifically, the guide member 1360 may be coupled to the medical device 30, and when the first housing 110 moves from the distal end to the proximal end relative to the second housing 120, the guide member 1360 may guide the medical device 30 to be applied to the host.

[0076] In some examples, the guide member 1360 may have a sharp object 1361 (see FIG. 6 ) coupled to the medical device 30 , thereby improving the convenience of partially implanting the medical device 30 under the host's skin.

[0077] In some examples, guide member 1360 may have a clamping seat 1362 (see FIG. 6 ) that secures a sharp object 1361 .

[0078] In some examples, the sidewall 1350, the first bottom 1330, and the second bottom 1340 can form a movable space for the guide member 1360 to move. In some examples, the medical device 30 can be placed in the movable space. This can prevent the guide member 1360 from being easily separated from the movable space.

[0079] Figure 8 is a cross-sectional view showing the cooperation between the guide member 1360 and the side wall 1350 according to an example of the present invention. In order to better illustrate the cooperation between the guide member 1360 and the side wall 1350, some parts or lines that may affect the description are omitted and simplified in Figure 8.

[0080] In some examples, guide member 1360 can be releasably retained to sidewall 1350 .

[0081] In some examples, a second drive mechanism 1370 (see FIG. 3 or FIG. 6 ) may be disposed between the guide member 1360 and the second base 1340. In other words, the movable assembly 130 may further include the second drive mechanism 1370, which may be disposed between the guide member 1360 and the second base 1340. In some examples, the second drive mechanism 1370 may apply a distal force to the guide member 1360. In this case, when the guide member 1360 is released from engagement with the sidewall 1350, the force applied by the second drive mechanism 1370 to the guide member 1360 can drive the guide member 1360 distally. This facilitates the decoupling of the guide member 1360 from the medical device 30 after the guide member 1360 guides the medical device 30 to the host, thereby improving the ease of operation of the application apparatus 10.

[0082] In some examples, the second driving mechanism 1370 can be a spring in a compressed state. In other examples, the second driving mechanism 1370 can also be a spring in a stretched state.

[0083] In some examples, guide member 1360 can include a second retaining arm 1363 (see FIG. 8 ). Second retaining arm 1363 can be releasably retained by sidewall 1350 .

[0084] In some examples, second retaining arm 1363 may be formed on an outer periphery of clamping seat 1362 .

[0085] In some examples, the second retaining arm 1363 may gradually expand in a direction from the proximal end to the distal end. The distal end of the second retaining arm 1363 may abut against the side wall 1350.

[0086] In some examples, sidewall 1350 may include a retaining notch 1351 (see FIG. 8 ) that cooperates with second retaining arm 1363. In some examples, second retaining arm 1363 may abut retaining notch 1351, thereby enabling second retaining arm 1363 to be releasably retained by sidewall 1350.

[0087] In some examples, a trigger mechanism 1230 (see FIG5 ) may be formed in the second housing 120. In some examples, the trigger mechanism 1230 may act on the second retaining arm 1363 during the movement of the movable assembly 130 toward the proximal end. Specifically, the trigger mechanism 1230 may act on the distal end of the second retaining arm 1363 during the movement of the guide member 1360 toward the proximal end. In this case, the trigger mechanism 1230 acting on the second retaining arm 1363 can deflect the second retaining arm 1363 toward the central axis of the movable assembly 130, thereby canceling the contact between the second retaining arm 1363 and the side wall 1350. As a result, the guide member 1360 can move toward the distal end under the action of the second drive mechanism 1370, thereby improving the convenience of canceling the coupling between the guide member 1360 and the medical device 30.

[0088] In some examples, the trigger mechanism 1230 can be formed on the inner wall of the second housing 120. In some examples, the trigger mechanism 1230 can be a protruding structure formed on the inner wall of the second housing 120.

[0089] In the present invention, "whole-body press triggering" can be understood as pressing the first shell 110 toward the proximal end, so that the application device 10 triggers the action of applying the CGM to the skin surface of the human body.

[0090] In a preferred embodiment of the present invention, before the application device 10 triggers the application action, the application device 10 may be in an initial state. In the initial state, the second housing 120 protrudes proximally from the first housing 110 and the first housing 110 is movable from the distal end to the proximal end relative to the second housing 120. The first retaining portion 1321 and the second retaining portion 1322 of the retaining mechanism 1320 are releasably retained by the second limiting mechanism 1120 of the first housing 110 and the third limiting mechanism 1220 of the second housing 120, respectively. The second retaining arm 1363 of the guide member 1360 is releasably retained by the side wall 1350. The first drive mechanism 140 and the second drive mechanism 1370 are configured to be in a compressed state.

[0091] In a preferred embodiment of the present invention, when the applying device 10 is in the initial state, the first shell 110 is pressed toward the proximal end, and the first shell 110 will move from the distal end to the proximal end relative to the second shell 120. Since the first retaining portion 1321 is releasably retained in the second limiting mechanism 1120, under the action of the first driving mechanism 140, the movable component 130 and the first shell 110 will initially remain relatively stationary, and the movable component 130 will move toward the proximal end relative to the second shell 120.

[0092] In a preferred embodiment of the present invention, during the movement of the movable component 130 toward the proximal end, the third limiting mechanism 1220 and the second retaining portion 1322 gradually cancel the retention and the third limiting mechanism 1220 gradually increases the force applied to the second retaining portion 1322 toward the central axis of the movable component 130, so that the first retaining arm 1323 deflects toward the central axis of the movable component 130, and the deflected first retaining arm 1323 drives the first retaining portion 1321 to deviate toward the central axis of the movable component 130, and then the third limiting mechanism 1220 releases the second retaining portion 1322 and the second limiting mechanism 1120 releases the first retaining portion 1321, thereby releasing the first shell 110 and the second shell 120 (that is, the released movable components 130 both move relative to the first shell 110 and the second shell 120).

[0093] In a preferred embodiment of the present invention, the released active component 130 will move toward the proximal end under the action of the first driving mechanism 140 and guide the CGM to be applied to the skin surface of the human body. When the active component 130 moves to the designed position (that is, when the active component 130 moves to the trigger mechanism 1230 acts on the second retaining arm 1363), the second retaining arm 1363 is no longer in contact with the side wall 1350, so that the guide member 1360 is released by the side wall 1350. The released guide member 1360 will move toward the distal end under the action of the second driving mechanism 1370 and be decoupled from the medical device 30.

[0094] In the present invention, the first shell 110 and the second shell 120 can release the retaining mechanism 1320 by moving the first shell 110 from the distal end toward the proximal end relative to the second shell 120. In other words, by pressing the first shell 110, the movable component 130 can be moved from the distal end toward the proximal end relative to the second shell 120 to guide the medical device 30 to be applied to the host, thereby improving the convenience of the triggering method.

[0095] Although the present invention has been described in detail above with reference to the accompanying drawings and examples, it should be understood that the above description does not limit the present invention in any form. Those skilled in the art may modify and alter the present invention as needed without departing from the spirit and scope of the present invention, and such modifications and alterations are intended to fall within the scope of the present invention.
