Description

Technical Field

[0001] The present application relates to the field of medical care technology, and in particular to a pushing mechanism and an analyte detection device equipped with the pushing mechanism. Background Art

[0002] An analyte sensor is a detection device that can comfortably, conveniently and continuously monitor the concentration of biological analytes in the human body and convert it into measurable parameters such as electrical signals. For example, an analyte sensor used to monitor glucose concentration in real time is usually called a continuous glucose monitoring system. The analyte sensor used to detect glucose concentration needs to be worn on the measured part of the human body through a specific push mechanism, that is, the analyte sensor is ejected from the inside through the push mechanism, and the fixation of the analyte sensor is released to complete the release, which is convenient for the detection operation of the analyte sensor.

[0003] In the related art, the push mechanism used for the analyte sensor is mostly disposable, that is, the push mechanism cannot be used again after it is ejected and released once, which results in a low utilization rate of the push mechanism and a high cost. Summary of the invention

[0004] Based on this, it is necessary to provide a reusable pushing mechanism suitable for the ejection and release of multiple analyte sensors, so as to improve the utilization rate of the pushing mechanism and reduce the cost of use.

[0005] A pushing mechanism is used to push an analyte sensor and comprises a fixed block, a pushing block and a retraction component; the pushing block is movably arranged on the fixed block and is provided with a containing cavity and a trigger buckle that can be engaged with the fixed block; the retraction component comprises a retraction block and a second elastic member, the retraction block is movably arranged on the pushing block, the second elastic member is pre-pressed between the retraction block and the pushing block, and the retraction block is provided with a retraction buckle that is engaged with the pushing block; the pushing block is configured to move in response to the triggering of the trigger buckle to push the retraction component, and the retraction block is configured to move in the opposite direction under the action of the second elastic member in response to the triggering of the retraction buckle to release the sensor; the pushing block can move in the opposite direction under the action of an external force to engage with the retraction block and press the second elastic member.

[0006] It is understandable that when the push block moves with the sensor through the accommodating cavity, the reverse movement of the retraction block relative to the push block can cause the limit buckle to disengage from the sensor. After the sensor loses the limiting effect of the limit buckle, it can escape from the accommodating cavity, thereby realizing the pop-up and release of the sensor. Moreover, due to the movable setting of the push block and the setting of the second elastic member, the push block can move in the opposite direction along the pop-up sensor to engage with the retraction block again to meet the pressure of the second elastic member, and can be used again for the pop-up and release of the sensor. Therefore, the push mechanism provided in the present application can be reused and is suitable for the pop-up and release of multiple sensors, so there is no need to configure a corresponding push mechanism for each sensor separately, thereby improving the utilization rate and reducing the use cost.

[0007] In some embodiments, the pushing mechanism further includes a first elastic member, the first elastic member is pressed between the pushing block and the fixed block, and the pushing block moves under the action of the first elastic member.

[0009] In some embodiments, the pushing block is provided with a retraction card hole, and the fixed block is provided with a retraction switch; in the first position, the retraction buckle abuts against the side of the retraction card hole away from the accommodating cavity along the direction of the central axis; in the second position, the retraction switch touches the retraction buckle to withdraw from the retraction card hole to release the engagement with the pushing block.

[0010] In some embodiments, the retraction buckle and the retraction switch slope cooperate.

[0011] In some embodiments, the fixing block is provided with a stop groove, and the pushing block is provided with a stop buckle; in the first position, the stop buckle is located in the stop groove and has no contact; in the second position, the stop buckle abuts against the side of the stop groove along the direction of the central axis toward the accommodating cavity.

[0012] In some embodiments, the retracting block is provided with a limiting buckle, the pushing block is provided with an avoidance groove, and the limiting buckle passes through the avoidance groove and extends into the accommodating cavity, so as to limit the analyte sensor in the accommodating cavity.

[0013] In some embodiments, the fixed block is provided with a first cavity, the pushing block is at least partially accommodated in the first cavity and is provided with a second cavity, and the retracting block is at least partially accommodated in the second cavity; the pushing mechanism also includes a shell, which is sleeved on the outside of the fixed block, and the shell is provided with a trigger member for triggering the trigger buckle.

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0043] See also Figures 1 to 11 , an embodiment of the present application provides a pushing mechanism 100, including a fixed block 110, a pushing block 120 and a retraction assembly. The pushing block 120 is movably arranged on the fixed block 110 and is provided with a trigger buckle 121, which is engaged with the fixed block 110. The pushing block 120 is also provided with a receiving cavity 122 for accommodating the analyte sensor 200. The retraction assembly includes a retraction block 130 and a second elastic member 150, the retraction block 130 is movably arranged on the pushing block 120, and the second elastic member 150 is pre-pressed between the retraction block 130 and the pushing block 120. The retraction block 130 is provided with a retraction buckle 131 and a limit buckle 132, the retraction buckle 131 is engaged with the pushing block 120, and the limit buckle 132 is used to limit the analyte sensor 200 in the receiving cavity 122. In actual use, the push block 120 is configured to move in response to the triggering of the trigger buckle 121 to push the retraction assembly; the retraction block 130 is configured to move in the opposite direction under the action of the second elastic member 150 in response to the triggering of the retraction buckle 131 to release the analyte sensor 200. At the same time, the push block 120 can move in the opposite direction under the action of an external force to engage with the retraction block 130 and press the second elastic member 150.

[0044] In actual use, the analyte sensor 200 is installed in the accommodating cavity 122, and is limited by the limit buckle 132 on the retraction block 130 to prevent the analyte sensor 200 from being separated from the accommodating cavity 122. Taking the case that both the push block 120 and the retraction block 130 move relative to the fixed block 110 in the vertical direction (i.e., the Z-axis direction in the three-dimensional coordinate system) as an example, the accommodating cavity 122 is arranged at the lower part of the push block 120. Due to the pressing arrangement of the second elastic member 150, the second elastic member 150 has an upward pushing force on the retraction block 130, so the retraction block 130 can move upward under the action of the second elastic member 150. Therefore, by using the reverse movement of the push block 120 and the retraction block 130, the limit buckle 132 can be urged to move up with the retraction block 130 to be separated from the analyte sensor 200. Specifically, before the retraction block 130 moves upward, the retraction assembly and the analyte sensor 200 move downward with the push block 120, and then the analyte sensor 200 can be released from the accommodating cavity 122 after the limit buckle 132 is loosened, thereby releasing the analyte sensor 200. When the analyte sensor 200 needs to be installed, it is placed in the accommodating cavity 122, and the push block 120 is pressed in the direction opposite to the moving direction of the push block 120 until the push block 120 is again engaged with the retraction buckle 131 on the retraction block 130, and the limit buckle 132 is again engaged with the analyte sensor 200 to limit the position. Figure 8 The middle arrow indicates the moving direction of the retracting block 130 under the action of the second elastic member 150 .

[0045] That is to say, the push mechanism 100 provided in this embodiment utilizes the reverse movement of the push block 120 and the retract block 130 to meet the pop-up and release of the analyte sensor 200; and, due to the movable setting of the push block 120 and the setting of the second elastic member 150, the push block 120 can move in the reverse direction of the pop-up analyte sensor 200 to engage with the retract block 130 and the fixed block 110 again, and meet the pressure setting of the second elastic member 150, and can be used again for the pop-up and release of the analyte sensor 200. Therefore, the push mechanism 100 provided in this embodiment can be reused and is suitable for the pop-up and release of multiple analyte sensors 200, so there is no need to separately configure a corresponding push mechanism 100 for each analyte sensor 200, thereby improving the utilization rate and reducing the use cost.

[0046] See also Figures 1 to 11In some specific embodiments, the pushing mechanism 100 further includes a first elastic member 140, which is pressed between the pushing block 120 and the fixed block 110, and the pushing block 120 moves under the action of the first elastic member 140. That is, since the first elastic member 140 is pressed relative to the pushing block 120 and the fixed block 110, it has a downward force on the pushing block 120, so after the trigger buckle 121 is triggered to release the snap fit with the fixed block 110, the pushing block 120 moves downward under the action of the first elastic member 140 to achieve the pushing of the aforementioned retraction component and the analyte sensor 200. When the pushing block 120 is pressed by an external force to move in the reverse direction until it snaps into fit with the fixed block 110 again, the first elastic member 140 is pressed again. Among them, the first elastic member 140 and the second elastic member 150 are both compression springs, and the first elastic member 140 is located above the second elastic member 150.

[0047] Alternatively, the pushing of the pushing block 120 may also be done by the user holding the trigger buckle 121 to push the pushing block 120 to move downward relative to the fixed block 110. Alternatively, a tension spring may be provided between the pushing block 120 and the fixed block 110, and the tension spring is in a stretched state. After the trigger buckle 121 releases the engagement with the fixed block 110, the pushing block 120 moves downward under the action of the tension spring. It is sufficient that the pushing block 120 moves linearly downward when the analyte sensor 200 is ejected.

[0048] See also Figures 6 to 11 In some specific embodiments, the fixed block 110 is provided with a first cavity 115, the push block 120 is at least partially accommodated in the first cavity 115, and the push block 120 is provided with a second cavity 126, and the retraction block 130 is at least partially accommodated in the second cavity 126. That is to say, the fixed block 110, the push block 120 and the retraction block 130 are all cylindrical and are sequentially arranged from the outside to the inside. Such a setting reduces the overall volume of the push mechanism 100, is more convenient for users to wear, and reduces the weight. For example, they can all be cylindrical and are sequentially arranged from small to large and from outside to inside according to the diameter. The retraction block 130 has the smallest diameter and the fixed block 110 has the largest diameter. It can also be a quadrangular prism, a pentagonal prism, a triangular prism, etc. It only needs to meet the assembly, ejection, release and repeated use of the analyte sensor 200.

[0049] like Figure 4 and Figure 5As shown, a partition 128 is provided between the second cavity 126 and the accommodating cavity 122 to separate them, and the retraction block 130 is provided with a third cavity 134, and the second elastic member 150 is at least partially accommodated in the third cavity 134 and pressed between the partition 128 and the retraction block 130. At the same time, the side of the second cavity 126 away from the accommodating cavity 122 is an opening 127, and a limiting pillar 133 is convexly provided on the upward side of the retraction block 130. When the retraction block 130 moves upward under the action of the second elastic member 150, the limiting pillar 133 passes through the opening 127 and abuts against the top of the fixed block 110 for limiting; and, it is precisely because of the limiting effect of the limiting pillar 133 that it is convenient to press the analyte sensor 200 into the accommodating cavity 122.

[0050] like Figure 4 and Figure 5 As shown, further, a first guide structure is provided between the fixed block 110 and the push block 120, and a second guide structure is provided between the push block 120 and the retracting block 130 to guide the movement. The first guide structure includes a first slide groove 172 and a first slide bar (not shown in the figure), one of which is provided on the fixed block 110, and the other is provided on the push block 120, and the first slide bar is inserted in the first slide groove 172 and slides in the first slide groove 172. The first slide groove 172 and the first slide bar are both arranged in the vertical direction. For example, the fixed block 110 may be provided with a first slide groove 172 in the cavity wall of the first cavity 115, and the outer wall of the push block 120 may be provided with a first slide bar; or, the outer wall of the push block 120 may be provided with a first slide groove 172 in the outer wall, and the cavity wall of the first cavity 115 may be provided with a first slide bar. The second guide structure includes a second slide groove 173 and a second slide bar 174, one of which is provided on the push block 120 and the other is provided on the retract block 130. The configuration of the second guide structure is basically similar to the first guide structure, so it is not described in detail. The push block 120 may have a second slide bar 174 convexly provided on the wall of the second cavity 126, and the outer wall of the retract block 130 may have a second slide groove 173 concavely provided; or vice versa.

[0051] In summary, it can be seen that the cooperation of the slide groove and the slide bar can guide the movement of the push block 120 relative to the fixed block 110, and the movement of the retracting block 130 relative to the push block 120; and, such a setting can also limit the mutual rotation between the push block 120 and the fixed block 110, and the mutual rotation between the retracting block 130 and the push block 120, thereby improving the assembly stability.

[0052] See also Figures 2 to 11As some of them are exemplary, the fixed block 110 has a central axis, taking the aforementioned Z axis as an example. The fixed block 110 is provided with a first clamping position 111 and a second clamping position 112 arranged at intervals in the vertical direction, and the first clamping position 111 is arranged above the second clamping position 112. The push block 120 has a first position and a second position relative to the fixed block 110. In the first position, the trigger buckle 121 on the push block 120 is clamped in the first clamping position 111 to satisfy the clamping fit of the fixed block 110, and the first elastic member 140 and the second elastic member 150 are both in a pressed state. It can be understood that in the first position, that is, the state in which the push mechanism 100 is equipped with the analyte sensor 200 and the analyte sensor 200 is not ejected, which is the initial state in which the analyte sensor 200 is assembled relative to the push mechanism 100. In the second position, the trigger buckle 121 on the pushing block 120 is engaged with the second engaging position 112 , and the retracting block 130 moves in the reverse direction under the action of the second elastic member 150 to release the analyte sensor 200 .

[0053] That is to say, in the initial state, the analyte sensor 200 is installed in the accommodating cavity 122 and is limited by the limit buckle 132 on the retracting block 130. The retracting buckle 131 on the retracting block 130 is engaged with the pushing block 120, and the trigger buckle 121 on the pushing block 120 is engaged with the first engaging position 111 of the fixed block 110. When the trigger buckle 121 is triggered, the engaging state with the first engaging position 111 can be released, the pushing block 120 loses the limiting effect with the fixed block 110, and the elastic potential energy of the first elastic member 140 is released to push the pushing block 120 to move downward, and the pushing block 120 drives the analyte sensor 200 and the retracting block 130 to move downward synchronously, so that the analyte sensor 200 pops out. At this time, the limiting buckle 132 on the retracting block 130 is still engaged with the analyte sensor 200, so the analyte sensor 200 is still limited in the accommodating cavity 122, but the position in the vertical direction is changed.

[0054] When the push block 120 moves to the second position 112 where the trigger buckle 121 is engaged with the fixed block 110, the push block 120 is located at the second position. At this time, due to the limitation of the second position 112, the position of the push block 120 remains unchanged, that is, the push block 120 is kept basically stable. Then, the retraction buckle 131 on the retraction block 130 is triggered to release the engagement with the push block 120, the retraction block 130 loses the limiting effect with the push block 120, the elastic potential energy of the second elastic member 150 is released to push the retraction block 130 to move upward, and the limiting buckle 132 on the retraction block 130 moves upward synchronously to disengage the analyte sensor 200 in the accommodating cavity 122. The analyte sensor 200 loses the limiting effect of the limiting buckle 132 and falls out of the accommodating cavity 122 to meet the release of the analyte sensor 200.

[0055] After the previous analyte sensor 200 is ejected and released, the next analyte sensor 200 can be placed in the accommodating cavity 122 and the push block 120 can be pressed upward, so that the trigger buckle 121 on the push block 120 is disengaged from the second clamping position 112 and moves upward to retreat to the first clamping position 111, and engages with the first clamping position 111. At this time, the first elastic member 140 is compressed, and the push block 120 engages with the retraction buckle 131 on the retraction block 130, and the second elastic member 150 is also in a compressed state, that is, it is restored to the initial state, so that the analyte sensor 200 can be ejected and released again.

[0056] In summary, by utilizing the setting of the first clamping position 111 and the second clamping position 112 on the fixed block 110, the pushing block 120 can be stably maintained in the first position and the second position, thereby satisfying the pressing of the first elastic member 140 in the first position and the pushing block 120 will not move up with the retracting block 130 in the second position, thereby ensuring the stable release of the analyte sensor 200.

[0057] like Figures 2 to 4 As shown, in some specific embodiments, the first clamping position 111 and the second clamping position 112 are both hole structures provided on the fixed block 110, for example, they can be rectangular holes. When in the first clamping position 111, the trigger buckle 121 abuts against the lower edge of the first clamping position 111 to achieve the limit position with the fixed block 110, so as to press the first elastic member 140 to store energy; when in the second clamping position 112, the trigger buckle 121 abuts against the lower edge of the second clamping position 112 to achieve the limit position with the fixed block 110, and the first elastic member 140 always applies a downward force to the push block 120 to maintain the push block 120 basically stable, thereby facilitating the release of the analyte sensor 200.

[0058] See also Figures 4 to 11 Optionally, the push block 120 is provided with a retraction hole 123, and the fixed block 110 is provided with a retraction switch 113. In the first position, the retraction buckle 131 abuts against the side of the retraction hole 123 away from the accommodating cavity 122 in the vertical direction to meet the engagement between the retraction block 130 and the push block 120 and keep the second elastic member 150 in a compressed state. In the second position, the retraction switch 113 contacts the retraction buckle 131 to exit the retraction hole 123 to release the engagement with the push block 120, and the elastic potential energy of the second elastic member 150 is released to contact the retraction block 130 to move upward, thereby releasing the analyte sensor 200.

[0059] That is, the setting of the retraction switch 113 is used to cause the retraction buckle 131 to be triggered and disengage from the engagement with the push block 120, and then move upward under the action of the second elastic member 150, so as to facilitate the disengagement of the limit buckle 132 and release the analyte sensor 200. The retraction buckle hole 123 on the push block 120 and the trigger buckle 121 are arranged at intervals around the Z axis to ensure that the engagement between the two does not interfere with each other.

[0060] In actual use, the retraction buckle 131 and the retraction switch 113 are matched with each other on the inclined surface. Among them, the retraction switch 113 is set at a position adapted to the second clamping position 112. Since the second clamping position 112 is used to clamp with the trigger buckle 121, and the trigger buckle 121 and the retraction buckle 131 are arranged at intervals, the retraction switch 113 and the second clamping position 112 are arranged at intervals around the Z axis without interfering with each other. When the push block 120 moves down to the second clamping position 112 under the action of the first elastic member 140, since the size of the second clamping position 112 along the vertical direction is larger than the size of the trigger buckle 121 along the vertical direction, there is still a margin of movement under the action of the first elastic member 140, which results in sufficient time and distance for the retraction switch 113 to abut against the retraction buckle 131 through the inclined surface, so that it moves out of the retraction clamp hole 123, releases the clamping cooperation with the push block 120, and then moves up under the action of the second elastic member 150.

[0061] The retraction block 130 will not move down to the point where the retraction buckle 131 is located below the retraction switch 113 .

[0062] like Figure 6 , Figure 8 and Fig.10 As shown, in some specific embodiments, the retraction switch 113 is provided with a first inclined surface 1131, and the retraction buckle 131 is provided with a second inclined surface 1311. The first inclined surface 1131 is inclined from top to bottom and from outside to inside, and the second inclined surface 1311 is adapted thereto. Such a setting ensures that the retraction block 130 can cooperate with the retraction switch 113 on the downward movement path of the push block 120 to release the clamping fixation.

[0063] See also Figure 3 , Figure 4 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As another option, the fixed block 110 is provided with a stop groove 114, and the push block 120 is provided with a stop buckle 124. In the first position, the stop buckle 124 is located in the stop groove 114 and has no contact. In the second position, the stop buckle 124 abuts against the side of the stop groove 114 facing the accommodating cavity 122 in the vertical direction. Among them, the stop groove 114 is a rectangular groove, and the length direction is along the vertical direction. The stop groove 114 is set at the upper position of the fixed block 110 to avoid the first clamping position 111 and the retraction switch 113. The cooperation between the stop groove 114 and the stop buckle 124 is intended to limit the downward movement of the push block 120 in the vertical direction, so as to prevent the push block 120 from directly detaching from the fixed block 110 under the action of the first elastic member 140.

[0064] In some specific embodiments, the stop slot 114 can penetrate to the top of the fixed block 110, so that the top of the fixed block 110 is not blocked at the position corresponding to the stop slot 114. Therefore, when the push block 120 is located at the first position 111 (i.e., the first position), the stop buckle 124 is located above the stop slot 114 and will not be limited by the fixed block 110. When the trigger buckle 121 on the push block 120 is triggered to cause the push block 120 to move downward under the action of the first elastic member 140, the stop buckle 124 moves downward in the stop slot 114 until the stop buckle 124 abuts against the lower edge of the stop slot 114, and the trigger buckle 121 moves to the second position 112.

[0065] like Figures 4 to 11 As shown, the trigger buckle 121 has a flat surface on its downward side and an inclined surface on its upward side. The flat surface on the trigger buckle 121 is conducive to abutting and limiting with the lower edges of the first clamping position 111 and the second clamping position 112. The inclined surface on the trigger buckle 121 is conducive to the push block 120 being pressed and disengaged from the second clamping position 112. At the same time, the retraction buckle 131 has an inclined surface on its downward side (i.e., the aforementioned second inclined surface 1311) and a flat surface on its upward side. The inclined surface on the retraction buckle 131 is conducive to cooperating with the first inclined surface 1131 on the retraction switch 113 to realize release of the clamping. The flat surface on the retraction buckle 131 is conducive to abutting and limiting with the upper edge of the retraction clamping hole 123 on the push block 120 to maintain the compressed state of the second elastic member 150. The downward side of the stop buckle 124 is a flat surface, and the upward side is an inclined surface. The flat surface on the stop buckle 124 is conducive to abutting and limiting with the lower edge of the stop groove 114 to prevent the pushing block 120 from being separated from the fixing block 110.

[0066] In some specific embodiments, the push block 120 is provided with a plurality of stop buckles 124 and retraction holes 123, which are spaced and staggered around the Z axis with the trigger buckle 121, each stop buckle 124 corresponds to a stop slot 114, each retraction hole 123 corresponds to a retraction buckle 131, and each retraction buckle 131 corresponds to a retraction switch 113. Such a configuration improves connection reliability and ensures uniform force.

[0067] like Figure 4 , Figure 5 , Figure 7 , Fig. 9 and Fig.11 As shown, further, a avoidance groove 125 is provided at the lower position of the push block 120, and the limit buckle 132 on the retracting block 130 passes through the avoidance groove 125 and extends into the accommodating cavity 122 to engage with the analyte sensor 200. Among them, there are also multiple limit buckles 132, for example, there can be two, three, four, etc., which are arranged at intervals around the Z axis, and each limit buckle 132 corresponds to an avoidance groove 125, so as to improve the limiting effect of the analyte sensor 200. In some specific embodiments, there are two limit buckles 132, which are arranged oppositely and at intervals. The analyte sensor 200 is correspondingly provided with a first limit groove that engages with the limit buckle 132.

[0068] like Figures 1 to 11 As shown, in actual use, the pushing mechanism 100 also includes a shell 160, which is sleeved on the outside of the fixed block 110. The shell 160 is provided with a trigger 161, and the trigger 161 is used to trigger the trigger buckle 121. The shell 160 plays a protective role, and the trigger buckle 121 can be driven to exit the first clamping position 111 by the setting of the trigger 161, which is convenient for operation. Among them, a notch 162 is provided at the shell 160, and the part of the position surrounded by the notch 162 is used as the trigger 161, that is, the trigger 161 for triggering the trigger buckle 121 is formed on the structure of the shell 160 itself, and the user can trigger the trigger buckle 121 by pressing the trigger 161. The trigger 161 is provided with a protrusion on the side facing the fixed block 110, which is conducive to pressing the trigger buckle 121 on the pushing block 120.

[0069] like Figures 1 to 3 , Figure 6 , Figure 8 and Fig.10As shown, a limiting clamp hole 163 may be provided on the housing 160, and an assembly clamp 116 may be provided on the fixed block 110, and the assembly clamp 116 may be clamped in the limiting clamp hole 163; and a boss may be convexly provided on the lower edge of the fixed block 110 to abut against the lower edge of the housing 160. In this way, the axial limiting of the fixed block 110 and the housing 160 may be achieved. At the same time, a second limiting groove 171 may be concavely provided on the outer wall of the fixed block 110, and a limiting convex strip may be convexly provided on the inner wall of the housing 160, and the limiting convex strip may be inserted into the second limiting groove to achieve the rotation limiting of the fixed block 110 relative to the housing 160. Conversely, the assembly clamp may be provided on the housing 160, the limiting clamp hole may be provided on the fixed block 110, the limiting convex strip may be provided on the fixed block 110, and the second limiting groove may be provided on the housing 160.

[0070] like Figures 6 to 11 As shown, further, two trigger buckles 121 may be provided and arranged 180 degrees apart around the Z axis. Each trigger buckle 121 corresponds to a trigger member 161, and the user can realize the ejection and release of the analyte sensor 200 by pinching a trigger member 161 with two fingers respectively.

[0071] Further, a position indicator (not shown in the figure) is provided at the trigger 161 to indicate the position of the push block 120, so as to facilitate the user to judge whether the analyte sensor 200 is in an assembled state or a released state. Specifically, position sensors may be provided at the first and second positions 111 and 112 in the housing 160, respectively, and an alarm device may be provided at the housing 160, such as lamp beads of different colors. When the position sensor at the first position 111 detects the trigger buckle 121, a red light may be turned on; when the position sensor at the second position 112 detects the trigger buckle 121, a green light may be turned on. Of course, two color blocks spaced in the vertical direction, such as a red block and a green block, may also be provided at the push block 120, and holes may be opened on the housing 160 and the fixed block 110, and when the push block 120 is in the first and second positions 111 and 112, respectively, the color blocks corresponding to the color blocks seen from the openings are different. The first position 111 corresponds to a red block, and the second position 112 corresponds to a green block, and the red block is arranged below the green block. Of course, the housing 160 may also be set to be transparent, so that the user can directly observe the position of the trigger buckle 121 relative to the first clamping position 111 and the second clamping position 112. This is only an example, as long as it can meet the user's reminder.

[0072] Alternatively, the triggering of the trigger buckle 121 can be realized by electric mode in addition to the above-mentioned user's hand pinching. For example, an electric drive structure can be set in the housing 160, and the electric drive structure serves as the trigger member 161 of the trigger buckle 121. When the electric drive structure receives the trigger signal that needs to release the analyte sensor 200, the trigger buckle 121 can be driven to exit the first clamping position 111 to release the clamping limit. The electric drive structure includes a signal receiving unit and a driving unit, and the signal receiving unit is used to receive the trigger signal applied by the user, and the driving unit is used to drive the trigger buckle 121 to move. An operation button can also be set on the housing 160, which is electrically connected to the signal receiving unit, and the operation button applies an instruction and is received by the controller. After the analysis process, the instruction is transmitted to the signal receiving unit, and then the drive unit is controlled to actuate. Wherein, the signal control between the operation button, the signal receiving unit and the drive unit is an existing mature basis, which will not be repeated here.

[0073] The driving part may include a motor and a cam. When the motor is started to drive the cam to rotate, the cam contacts the trigger buckle 121 on the push block 120 to release the engagement limit with the first clamping position 111. A reduction gear may be provided between the motor and the cam to ensure that the cam speed is small and stable.

[0074] like Figures 6 to 11 As shown, another embodiment of the present application provides an analyte detection device, including the aforementioned push mechanism 100 and an analyte sensor 200, which are detachably connected, and the analyte sensor 200 is configured to pop out and release in response to the activity of the push mechanism 100. The pop-up and release process of the sensor has been described in detail above and will not be repeated here. The specific structure of the analyte sensor 200 is described in detail below.

[0075] Most analyte sensors include a sensor and a transmitter. The sensor is used to detect the concentration of the analyte and transmit the signal to the transmitter, which then sends the detection signal to the terminal. In a split analyte sensor, after a period of use, the sensor needs to be disassembled from the transmitter and replaced with a new one; that is, the sensor as a consumable needs to be replaced regularly, while the transmitter does not need to be replaced and can be reused. Therefore, this poses a greater challenge to the power supply requirements of the transmitter.

[0076] In the related art, the transmitter uses disposable batteries, which are replaced with new batteries after the batteries are exhausted. However, due to the small size of the analyte sensor itself, the space for installing batteries on the transmitter is also small. Frequent replacement of batteries is not only inconvenient to operate, but also easily causes wear and tear on the transmitter's own structure, and there will also be problems such as dust accumulation, which is not conducive to the long-term use of the transmitter. In some cases, the transmitter uses rechargeable batteries, but repeated charging will cause the battery capacity to decrease, reduce the battery life, and is not conducive to the long-term use of the transmitter.

[0077] See also Fig.12 and Fig.13 As shown, another embodiment of the present application provides an analyte sensor 200, including a transmitting component 210 and a sensing component 220, which are separately formed and detachably connected. A snap-fit ​​structure 230 is provided between the transmitting component 210 and the sensing component 220 to achieve a detachable connection between the two. Such a setting facilitates the direct disposal of the sensing component 220 when it expires, and then connects it to a new sensing component 220, so as to facilitate continued detection, reduce detection costs, and reduce resource waste.

[0078] The transmitting component 210 includes at least a transmitting circuit and an analysis and processing unit, and the sensing component 220 includes at least a detection structure 221 and a battery 222. The transmitting circuit and the analysis and processing unit can be electrically connected, and the detection structure 221 and the battery 222 can be electrically connected; and the battery 222 is electrically connected to the transmitting circuit through the detection structure 221, or the battery 222 and the detection structure 221 are both electrically connected to the transmitting circuit, so as to realize the demand for power supply to the transmitting circuit and the analysis and processing unit.

[0079] In actual use, the detection structure 221 includes a sensing electrode 2212 and a connecting board 2211 provided with a circuit. The sensing electrode 2212 and the battery 222 are electrically connected to the circuit on the connecting board 2211, and the circuit on the connecting board 2211 is electrically connected to the transmitting circuit.

[0080] The detection signal of the sensing electrode 2212 is transmitted to the transmitting circuit through the circuit on the connecting board 2211, and is transmitted to the analysis and processing unit through the transmitting circuit for analysis and processing, and then the signal is transmitted to the receiving terminal, which is convenient for the user to observe and judge; and the battery 222 provides power to the transmitting circuit through the circuit on the connecting board 2211 to meet the power supply demand. It is precisely because the battery 222 is integrated in the sensing component 220, so when the sensing component 220 is discarded, the battery 222 is also discarded, and when a new sensing component 220 is replaced, it is equivalent to replacing a new battery 222. In other words, the battery 222 can use a disposable battery 222, and the service life of the battery 222 is basically the same as the service life of the sensing electrode 2212. Therefore, when the service life of the sensing electrode 2212 expires, the service life of the battery 222 is also basically expired. For example, the sensing electrode 2212 generally lasts about 10-15 days, and the service life of the battery 222 is also maintained at about 10-15 days.

[0081] Therefore, in the analyte sensor 200 provided in this embodiment, two structures with a service life (i.e., the detection structure 221 and the battery 222) are integrated together, and can be disassembled relative to the transmitting component 210 after the expiration, and a new battery 222 is also replaced when a new sensing component 220 is replaced. With such a configuration, there is no need to frequently disassemble the battery 222 relative to the transmitting component 210, thereby avoiding the wear of the transmitting component 210 when the battery 222 is replaced separately, and also preventing the transmitting component 210 from easily accumulating dust; and there is no need to frequently charge the battery 222, thereby effectively ensuring the service life of the battery 222 and facilitating the long-term use of the transmitting component 210.

[0082] In actual use, the sensing electrode 2212 mostly includes a working electrode, a counter electrode and a reference electrode. The working electrode may have at least one test chemical sensitive to the analyte to be detected, the counter electrode is used to perform an electrochemical reverse reaction, and the reference electrode has a stable electrode potential. The above three electrodes are all mounted on a substrate and can then be integrated into a probe or other structure. The specific structure and working principle of the sensing electrode 2212 are existing mature technologies and do not belong to the invention of this application, so they will not be repeated here.

[0083] The specific structures of the sensing component and the transmitting component are first described in detail below.

[0084] See also Figures 13 to 16 Optionally, the sensing component 220 further includes a base 224. The sensing electrode 2212, the battery 222 and the connecting plate 2211 are all integrated into the base 224, and part of the sensing electrode 2212 passes through the side of the base 224 away from the transmitting component 210, and the base 224 is detachably connected to the transmitting component 210. It can be understood that, on the one hand, the base 224 is used to support and integrate the aforementioned three to form an integral structure, and can improve the protection of the aforementioned three; on the other hand, the base 224 is used to be detachably connected to the transmitting component 210, so as to realize the overall detachability of the sensing component 220 and the transmitting component 210, and the safety is higher. The base 224 is provided with a first penetration hole 2241 that penetrates along the thickness direction thereof, and part of the sensing electrode 2212 passes through the first penetration hole 2241 and extends to the side of the base 224 away from the transmitting component 210 for collection.

[0085] Furthermore, the sensing component 220 also includes a cover plate 225, which is buckled on the side of the base 224 facing the transmitting component 210, and is used to cooperate with the base 224 to form an assembly cavity for assembling the sensing electrode 2212, the battery 222 and the connecting plate 2211, so as to improve the protection of the three and avoid the circuit elements on the connecting plate 2211 from interfering with the circuit elements on the transmitting circuit board and affecting the performance.

[0086] See also Figures 13 to 16In actual use, a sealing structure 226 is provided between the base 224 and the cover plate 225, which is arranged around the first through hole 2241 on the base 224, so as to ensure the sealing of the first through hole 2241 and prevent external body fluids or impurities from penetrating into the assembly cavity through the first through hole 2241 and affecting the circuit elements on the connecting plate 2211. The connecting plate 2211 is provided with a through hole 2231. Since the connecting plate 2211 is arranged between the cover plate 225 and the base 224, the through hole 2231 is used to avoid the aforementioned sealing structure 226, and the circuit elements can be appropriately arranged with an offset relative to the first through hole 2241.

[0087] like Fig.13 and Fig.15 As shown, further, the sealing structure 226 is annularly arranged along the circumference of the first penetration hole 2241. Specifically, the sealing structure 226 includes a sealing slot 2261 and a sealing rib (not shown in the figure), one of which is arranged on the base 224, and the other is arranged on the cover plate 225, and the sealing rib is inserted into the sealing slot 2261. It can be understood that the sealing rib and the sealing slot 2261 cooperate to structurally seal the circumference of the first penetration hole 2241, thereby preventing liquid or impurities at the first penetration hole 2241 from penetrating.

[0088] For example, the sealing slot 2261 is provided on the base 224. Specifically, two annular convex ribs 2262 are provided on one side of the base 224 facing the cover plate 225, and the diameters of the two convex ribs 2262 are arranged from small to large and from inside to outside to surround the sealing slot 2261. The sealing rib is provided on the side of the cover plate 225 facing the base 224, and is inserted between the two convex ribs 2262 to form a circuitous sealing path to achieve a sealing effect. The number of the sealing slots 2261 can also be two, in which case three convex ribs 2262 and two sealing ribs are provided accordingly. Alternatively, more sealing slots 2261 are provided, for example, the number of the sealing slots 2261 is H, the number of the sealing ribs is the same as the number of the sealing slots 2261, and the number of the ribs 2262 is K=H+1.

[0089] Alternatively, the sealing slot 2261 may be provided on the cover plate 225, and the sealing rib may be provided on the base 224, as long as the two are plugged in and matched to achieve the effects of sealing, blocking water, blocking impurities, etc.

[0090] See also Figures 13 to 16Furthermore, a first enclosure 2251 is provided on the side of the cover plate 225 facing the base 224 and corresponding to the sensing electrode 2212. When the cover plate 225 is buckled on the base 224 and the sealing slot 2261 is plugged and matched with the sealing rib, the first enclosure 2251 is buckled and surrounded on the outer peripheral side of the sealing structure 226, and the extended end of the first enclosure 2251 is pressed on the connecting plate 2211. On the one hand, the first enclosure 2251 can be used as a second seal at the first penetration hole 2241, and the cooperation of the aforementioned sealing slot 2261 and the sealing rib is used as a seal to further improve the sealing performance; on the other hand, the first enclosure 2251, the cover plate 225 and the base 224 are jointly surrounded by a first cavity to improve the protection performance.

[0091] Optionally, taking the case where the battery 222 is disposed on the side of the connecting plate 2211 facing the cover plate 225 as an example, a second enclosure 2252 is disposed on the side of the cover plate 225 facing the base 224 and corresponding to the battery 222. The second enclosure 2252 is disposed on the outer peripheral side of the battery 222 to form a second cavity together with the cover plate 225 and the connecting plate 2211 to improve the protection of the battery 222. The second cavity and the first cavity can be connected to meet the compact structure setting and facilitate manufacturing and processing. Alternatively, the second cavity and the first cavity are not connected.

[0092] It is worth noting that, since the battery 222 and the sensing electrode 2212 are electrically connected via the circuit on the connecting plate 2211 , whether the second cavity is connected to the first cavity does not affect the above electrical connection.

[0093] In actual use, the detection structure 221 also includes a connector 2213, which is arranged on the connecting plate 2211 and connected to the sensing electrode 2212 to realize signal transmission. The connector 2213 and the battery 222 are both arranged on the side of the connecting plate 2211 away from the base 224, so as to reduce the distance between the connecting plate 2211 and the base 224, thereby reducing the thickness of the entire sensing component 220 and realizing a miniaturized design. When the connecting plate 2211 is assembled relative to the base 224, the rib 2262 on the base 224 passes through the through hole 2231 on the connecting plate 2211 and extends to the side of the connecting plate 2211 away from the base 224, further reducing the distance between the connecting plate 2211 and the base 224.

[0094] The rib 2262 is disposed on the base 224, and a through slot connected to the first through hole 2241 is disposed on the side of the connecting plate 2211 facing the cover plate 225. The sensing electrode 2212 passes through the first through hole 2241 and the through slot and is connected to the connector 2213.

[0095] Correspondingly, a third enclosure 2253 is provided on one side of the cover plate 225 facing the base 224 and corresponding to the position of the connector 2213. The third enclosure 2253 is arranged around the outer peripheral side of the connector 2213 to form a third cavity together with the cover plate 225 and the connecting plate 2211 to improve the protection of the connector 2213. The third cavity is connected to the first cavity to facilitate the connection between the sensing electrode 2212 and the connector 2213.

[0096] In some specific embodiments, the connector 2213 and the battery 222 are disposed on both sides of the first through hole 2241, and the third enclosure 2253 and the second enclosure 2252 are disposed on both sides of the first enclosure 2251, and the third cavity, the second cavity and the first cavity are connected. The first enclosure 2251, the second enclosure 2252 and the third enclosure 2253 all protrude toward one side of the emitting component 210.

[0097] Furthermore, one of the cover plate 225 and the base 224 is provided with an assembly slot, and the other is provided with an assembly protrusion, and both the assembly slot and the assembly protrusion are arranged in a ring shape and are arranged around the outer side of the connecting plate 2211. When the cover plate 225 and the base 224 are buckled, the assembly protrusion is inserted into the assembly slot. The plug-in cooperation of the assembly protrusion and the assembly slot can not only meet the assembly positioning of the base 224 and the cover plate 225 and improve the connection reliability, but also can be used for the waterproofing of the entire sensor component 220. For example, the edge of the base 224 may be recessed with an assembly slot, and the edge of the cover plate 225 may be convexly provided with an assembly protrusion. Alternatively, the edge of the base 224 may be convexly provided with an assembly protrusion, and the edge of the cover plate 225 may be recessed with an assembly slot.

[0098] The cover plate 225 and the base 224 may be fixed by bonding, clamping or screwing, and the battery 222 may also be bonded or welded to the connecting plate 2211. It is sufficient to ensure that the assembly is stable and reliable.

[0099] See also Figures 13 to 17As some examples, the connecting board 2211 is provided with a first connecting terminal 2232, and the transmitting circuit board is provided with a second connecting terminal 212, and the first connecting terminal 2232 and the second connecting terminal 212 are electrically connected to realize the signal transmission between the sensing component 220 and the transmitting component 210 and the power supply requirement of the battery 222 for the transmitting component 210. Among them, the cover plate 225 is provided with a second penetration hole at the position corresponding to the first connecting terminal 2232, and the first connecting terminal 2232 is electrically connected to the second connecting terminal 212 through the second penetration hole. In actual use, the number of electrodes in the sensing electrode 2212 is N, and the number of the first connecting terminals 2232 is M=2+N. It can be understood that, precisely because the sensing electrode 2212 and the battery 222 both need to transmit electrical signals through the first connecting terminal 2232, the number of the first connecting terminals 2232 is determined by the number of electrodes in the sensing electrode 2212 and the positive and negative poles of the battery 222. Generally, the battery 222 includes a positive electrode and a negative electrode, each corresponding to a first connection terminal 2232, which is “2” in the above expression.

[0100] The first connection terminal 2232 may be bonded or welded to the connection plate 2211 as long as it satisfies the requirement of electrical signal transmission.

[0101] like Fig.13 , Fig.16 and Fig.17 As shown, further, the sensing component 220 also includes a terminal seal 228, and the terminal seal 228 is provided with a third penetration hole 2281. The first connection terminal 2232 on the connecting plate 2211 is electrically connected to the second connection terminal 212 through the third penetration hole 2281, and the hole wall of the third penetration hole 2281 is tightly fitted with the outer side wall of the first connection terminal 2232 for sealing. Alternatively, the first connection terminal 2232 does not protrude from the third penetration hole 2281 to connect with the second connection terminal 212. It can be that the end portion of the first connection terminal 2232 and the end portion of the second connection terminal 212 are both located in the third penetration hole 2281, and the two are connected in the third penetration hole 2281 and are tightly fitted with the hole wall. Alternatively, the end of the first connection terminal 2232 is flush with the end of the third penetration hole 2281 facing the emitting component 210. Of course, the second connection terminal 212 may pass through the third through hole 2281 to connect with the first connection terminal 2232, or the end of the second connection terminal 212 may be flush with the side of the third through hole 2281 away from the emitting component 210. It mainly satisfies the sealing of the connection between the first connection terminal 2232 and the second connection terminal 212.

[0102] In actual use, the second through hole on the cover plate 225 is adapted to the terminal seal 228, so that part of the terminal seal 228 passes through the second through hole and protrudes from the side of the cover plate 225 away from the base 224. In this way, when the sensing component 220 is connected to the transmitting component 210, the terminal seal 228 is pressed between the cover plate 225 and the transmitting component 210. The transmitting seat 211 is provided with a second accommodating groove 2112 at a position facing the terminal seal 228 to accommodate the protruding part of the terminal seal 228 relative to the cover plate 225, and cooperate with the cover plate 225 to press the terminal seal 228.

[0103] like Fig.13 As shown, or alternatively, the terminal seal 228 is provided with a first sealing surface 2282 and a second sealing surface 2283, the first sealing surface 2282 is arranged on the outer peripheral side of the second sealing surface 2283, and is located below the second sealing surface 2283 (on the side facing the base 224), the first sealing surface 2282 is pressed between the connecting plate 2211 and the cover plate 225, and the second sealing surface 2283 is pressed between the cover plate 225 and the emitting component 210, forming a double seal to improve the sealing effect.

[0104] As another example, the connecting board 2211 in the sensing component 220 adopts a printed circuit board, that is, it is made by electronic printing technology. The connecting board 2211 itself serves as a substrate for assembling electronic parts, and point-to-point connections and printed components are formed on the substrate according to a predetermined design, which can take into account greater operating capabilities, faster operating speeds, smaller size, and lighter weight.

[0105] For example, the connecting plate 2211 adopts a flexible circuit board in a printed circuit board, which has the characteristics of high wiring density, light weight and thin thickness, and has high reliability and excellent flexibility (i.e., it can be bent freely). Therefore, the flexible circuit board is more conducive to integration in the sensing component 220, and the space occupancy is also small, which is conducive to the installation of a high-power battery 222, and ensures the service life matching the sensing electrode 2212. Alternatively, the connecting plate 2211 can also adopt a rigid circuit board in a printed circuit board, which has high mechanical strength and durability, can withstand greater mechanical pressure and vibration, and has a relatively stable structural layout. Therefore, when the terminal seal 228 is used to seal the first connecting terminal 2232 and the second connecting terminal 212, the terminal seal 228 can be pressed between the cover plate 225 and the connecting plate 2211, and the rigid circuit board can be snap-fitted with the base 224.

[0106] In other embodiments, the connecting board 2211 in the sensor component 220 may adopt a three-dimensional integrated circuit, which has the advantages of high density, high speed, multi-function, low power consumption, etc.

[0107] It should be noted that the configuration of the transmitting circuit board in the transmitting component 210 may be substantially similar to the configuration of the aforementioned connecting board 2211. Therefore, it will not be described in detail here.

[0108] like Fig.13 and Fig.17 As shown, in some other embodiments, the transmitting component 210 further includes a transmitting seat 211, the transmitting circuit board is disposed on the transmitting seat 211, and the transmitting seat 211 is detachably connected to the base 224 in the sensing component 220. Specifically, the transmitting seat 211 and the base 224 may be snap-fitted. The snap-fitting of the two will be described in detail later.

[0109] As for the transmitting seat 211 and the transmitting circuit board, the transmitting seat 211 can be wrapped around the outer side of the transmitting circuit board by integral potting, so that the transmitting seat 211 and the transmitting circuit board form an integral structure, and the connection is more tight, so that the transmitting circuit board will not be affected when the sensor component 220 is removed relative to the transmitting component 210. At the same time, the transmitting seat 211 is recessed with a first receiving groove 2111 for receiving each enclosure on the aforementioned cover plate 225.

[0110] Alternatively, the transmitting base 211 is formed with a cavity, the transmitting circuit board is arranged in the cavity, and the circuit elements thereon do not protrude from the cavity.

[0111] In actual use, the first connection terminal 2232 uses a conductive rubber connector, also known as a zebra rubber strip, which is formed by alternately stacking conductive silicone and insulating silicone and then vulcanizing. The conductive rubber connector does not require any welding, eliminating damage to thermal devices, so it can be used to connect some electronic components that are easily damaged by heat; and the conductive rubber connector is not only moisture-proof and corrosion-resistant, but also has buffering and shock-proof effects, and can adapt to various contact methods.

[0112] Alternatively, the first connection terminal 2232 can be made of conductive foam. Conductive foam refers to a flame retardant sponge wrapped with conductive cloth and then subjected to a series of treatments to make it have good surface conductivity, and can be easily fixed to the device to be shielded by gluing or other methods, such as aluminum foil cloth foam, conductive fiber foam, etc. Conductive foam is light in weight, has a reduced surface impedance, and is not dependent on environmental humidity.

[0113] Alternatively, the first connection terminal 2232 is made of conductive silicone. Conductive silicone has good low temperature resistance and electrical insulation performance, stable chemical properties, high voltage resistance, aging resistance, soft texture, and easy installation.

[0114] The second connection terminal 212 may also be made of a conductive rubber connector, conductive foam or conductive silicone, as long as it can meet the electrical connection between the first connection terminal 2232 and the second connection terminal 212 .

[0115] The detachable connection between the sensing component and the transmitting component is described in detail below.

[0116] See also Figures 12 to 19 As some of the optional ones, as mentioned above, the sensor component 220 and the transmitting component 210 are snap-fitted, specifically, the base 224 in the sensor component 220 is snap-fitted with the transmitting seat 211 in the transmitting component 210. The snap-fit ​​structure 230 includes a first snap-fit ​​arm 231 having a first snap-fit ​​hole 2311 and a first snap-fit ​​protrusion 232. It can be that one of the base 224 and the transmitting seat 211 is provided with the first snap-fit ​​protrusion 232, and the other is provided with the first snap-fit ​​hole 2311, and the first snap-fit ​​protrusion 232 is snap-fitted with the first snap-fit ​​hole 2311 to achieve the connection between the base 224 and the transmitting seat 211. When it is necessary to disassemble and replace the new sensor component 220, the first snap-fit ​​protrusion 232 is forced to move out of the first snap-fit ​​hole 2311 under the action of external force to release the snap-fit ​​effect.

[0117] In actual use, one transmitting component 210 can be adapted to multiple sensing components 220. When one sensing component 220 expires, it can be replaced with a new sensing component 220, and each sensing component 220 can be snap-fitted with the transmitting component 210. Taking the first snap-fit ​​232 provided on the transmitting component 210 as an example, the base corresponding to each sensing component 220 is provided with a first snap-fit ​​arm 231. When each sensing component 220 is disassembled relative to the transmitting component 210, the corresponding first snap-fit ​​arm 231 can be caused to break relative to the corresponding base 224, so that the snap-fit ​​can be released and disassembly can be achieved. For example, the first snap-fit ​​arm 231 can be broken by hand.

[0118] When the base 224 is provided with a first latching protrusion 232 , it can also be directly broken off.

[0119] In some specific embodiments, the base 224 is provided with a first clamping arm 231 extending toward the launching component 210 along its thickness direction, and the first clamping hole 2311 is formed in the first clamping arm 231. The first clamping protrusion 232 is convexly provided on the launching seat 211. The first clamping arm 231 is provided with an auxiliary breaking portion (not shown in the figure) in the middle of the first clamping hole 2311 or a position close to the middle. When disassembly is required, the first clamping arm 231 can be bent to break it from the auxiliary breaking portion, so that the clamping cooperation between the first clamping protrusion 232 and the first clamping hole 2311 can be released, and disassembly is achieved. In actual use, an avoidance groove 125 can be provided at the first clamping protrusion 232 of the launching seat 211, and the extended end of the first clamping arm 231 can protrude through the avoidance groove 125, so that the user can hold the extended end of the first clamping arm 231 and force it to break.

[0120] For example, if the projection of the first clamping hole 2311 along its own axis is a rectangle, and one of the long sides of the first clamping hole is close to the base 224, auxiliary breaking parts are provided on both sides in the length direction, and the two auxiliary breaking parts are basically flush to ensure balanced force. Alternatively, on the basis of the above, an auxiliary breaking part can also be provided on the side of the first clamping arm 231 along the width direction of the first clamping hole 2311 facing the emitting component 210. By providing multiple auxiliary breaking parts, more labor is saved.

[0121] In actual use, a plurality of spaced narrow openings may be provided along the thickness direction of the first clamping arm 231 to form an auxiliary breaking portion.

[0122] Alternatively, the first clamping arm 231 is provided on the transmitting seat 211 and extends toward the sensing component 220. The first clamping protrusion 232 is provided on the base 224, and an auxiliary breaking portion is provided at the connection between the first clamping protrusion 232 and the base 224. When disassembling, the first clamping protrusion 232 can be broken off from the auxiliary breaking portion to release the clamping fit with the first clamping hole 2311. The first clamping protrusion 232 passes through the first clamping hole 2311 for easy operation by the user.

[0123] That is to say, in the snap-fit ​​method provided in this embodiment, the snap-fit ​​portion on the sensor component 220 can be destroyed to release the fit with the transmitting component 210; and the snap-fit ​​portion on the transmitting component 210 remains intact, which is convenient for recycling to adapt to more sensor components 220.

[0124] In actual use, there are multiple first clamping arms 231 and first clamping protrusions 232 in one-to-one correspondence, and the multiple first clamping arms 231 are arranged at intervals along the circumference of the base 224 .

[0125] like Figure 7 , Fig. 9 , Fig.11 , Fig.12 and Fig.13 As shown, in actual use, the analyte sensor 200 is released and ejected under the action of the push mechanism 100 for analyte concentration detection. Therefore, the sensing component 220 in the analyte sensor 200 is also provided with a clamping portion 240 for connecting with the push mechanism 100, and is detachably connected with the limit buckle in the push mechanism 100 through the clamping portion 240. Since when the analyte sensor 200 is connected to the push mechanism 100, the emitting component 210 faces the push mechanism 100, which facilitates the sensor electrode 2212 on the sensing component 220 to collect information. Therefore, the clamping portion 240 is provided on the sensing component 220 to increase the connection force arm between the analyte sensor 200 and the push mechanism 100 and improve the connection reliability.

[0126] Among them, the clamping part 240 can be the aforementioned first limiting groove, which is provided with a plurality of them and arranged at intervals along the circumferential direction, and each first limiting groove corresponds to a limiting buckle. Alternatively, the clamping part 240 can also be a limiting buckle, and the limiting buckle of the push mechanism 100 is formed with a groove for accommodating the limiting buckle. It can mainly cause the analyte sensor 200 to be disconnected and released from the push mechanism 100 under the action of external force. Another alternative is that the clamping part 240 can also be arranged around the sensor component 220, which is more conducive to the limiting buckle cooperation with the push mechanism 100.

[0127] In other embodiments, the aforementioned clamping portion 240 may also be disposed on the emitting component 210 .

[0128] In some specific embodiments, for example, the projection of the analyte sensor 200 in the thickness direction is a long strip, and both sides in the length direction are arc edges. In this case, a set of buckle structures 230 may be provided on both sides in the length direction, and a clamping portion 240 (such as a first limiting groove) may be provided on both sides in the width direction.

[0129] In yet another embodiment, the analyte sensor 200 may be coupled to the push mechanism 100 by magnetic adsorption; or, the analyte sensor 200 may be coupled to the push mechanism 100 by bonding. In this case, the push mechanism 100 may not be provided with a limit buckle 132 that cooperates with the clamping portion 240. It only needs to release the magnetic adsorption or adhesive fixation when the analyte sensor 200 is pushed out by the push mechanism 100. For example, through the magnetic adsorption of an electromagnet, the power is cut off synchronously when the analyte sensor 200 is ejected to release the analyte sensor 200.

[0130] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0131] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
