Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on September 30, 2024, with application number "202411395631.8" and invention name "A Online Blood Glucose Monitoring Device", all contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the technical field of medical equipment, and in particular to an online blood glucose monitoring device. Background Art

[0003] Diabetic patients can measure their blood sugar concentration by drawing blood from their fingertips. This measurement method requires patients to undergo regular testing to continuously track blood sugar indicators. Since blood sugar concentrations are constantly changing, fingertip blood measurements cannot help patients accurately track blood sugar concentrations in real time to improve their health quality.

[0004] CGM stands for Continuous Glucose Monitoring, which is a medical device used to monitor blood sugar levels in patients with diabetes. Compared with traditional blood sugar monitoring methods, CGM provides more continuous and detailed blood sugar level data, which can help users better manage their diabetes condition.

[0005] When using the CGM product, the user needs to place the shell of the CGM product on the skin and then press the trigger button. At this time, the puncture needle and sensor pin inside the shell move toward the skin and pierce the human skin. The biological enzyme on the sensor and the subcutaneous tissue fluid produce an electrochemical reaction, which is converted into an electrical signal and converted into a blood sugar value to provide to the user. When using existing products, the puncture needle has poor movement stability and is prone to shaking when piercing the human body, resulting in a larger wound area, a larger amount of bleeding, a stronger sense of pain, and a poor user experience. Summary of the invention

[0006] In view of this, the present application provides an online blood glucose monitoring device to help reduce the implantation wound area and reduce the user's pain.

[0012] In a possible implementation manner, one of the first guide portion and the second guide portion is a guide protrusion, and the other is a guide recess, and at least a portion of the guide protrusion extends into the guide recess.

[0013] In a possible implementation, at least one inner side wall of the guide recess is provided with at least two protrusions at intervals, the protrusions are provided to protrude toward the guide protrusion, and the protrusions are used to abut against the first guide portion.

[0014] In a possible embodiment, the first guide portion protrudes in a direction close to the implant unit, the second guide portion protrudes in a direction close to the fixing seat, the first guide portion abuts against the implant unit and / or the second guide portion abuts against the fixing seat.

[0015] In a possible implementation manner, among the surfaces where the first guide portion and the second guide portion contact each other, one is a plane and the other is an arcuate surface.

[0016] In a possible implementation, a third guide portion is provided on one of the fixing seat and the implant unit, and the third guide portion is extended along the first direction and protrudes in a direction close to the other and abuts against the other.

[0018] In a possible implementation, the implant unit includes an auxiliary needle assembly and a puncture assembly connected to the auxiliary needle assembly, and the puncture assembly can move relative to the auxiliary needle assembly along a second direction, and the first direction is opposite to the second direction;

[0019] The needle-assisting assembly includes a fourth guide portion extending along the second direction, and the puncture assembly includes a fifth guide portion extending along the second direction. The fourth guide portion cooperates with the fifth guide portion to guide the movement of the puncture assembly.

[0020] In a possible implementation manner, one of the fourth guide portion and the fifth guide portion is a guide protrusion, and the other is a guide recess, and at least a portion of the guide protrusion extends into the guide recess.

[0024] The present application provides an online blood glucose monitoring device including a fixed seat and an implant unit, wherein the implant unit can be slidably installed in the fixed seat and can move relative to the fixed seat along a first direction. The fixed seat is provided with a first guide portion extending along the first direction, and the implant unit includes a second guide portion extending along the first direction and a second limiting portion capable of elastically abutting against the inner wall of the fixed seat.

At the same time, during the movement of the implant unit relative to the fixed seat, the second limiting portion can elastically abut against the inner wall of the fixed seat, thereby guiding the movement of the implant unit relative to the fixed seat. By providing the first guide portion, the second guide portion and the second limiting portion, the relative movement of the implant unit and the fixed seat can be guided, thereby improving the stability of the movement of the implant unit. Since the second limiting portion can elastically abut against the inner wall of the fixing seat, when the second limiting portion shakes, tilts, etc. during movement, the second limiting portion can undergo elastic deformation.

DETAILED DESCRIPTION

[0051] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0052] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0053] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0054] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0055] like Figure 1 As shown, the embodiment of the present application provides an online blood glucose monitoring device for monitoring the blood glucose of a human body. The monitoring unit 3 can be implanted in the body to monitor the blood glucose of the implanted object. Figure 2 As shown, the online blood glucose monitoring device includes a fixing seat 1, an implant unit 2, a monitoring unit 3 and a mounting seat 4. The fixing seat 1 can be set in the housing 8 of the online blood glucose monitoring device, the implant unit 2 can be slidably installed in the fixing seat 1, and the monitoring unit 3 can be detachably installed on the implant unit 2. The implant unit 2 can move relative to the fixing seat 1 along a first direction, and at the same time drive the monitoring unit 3 to move from a first position to a second position along the first direction. The mounting seat 4 is used to accommodate the monitoring unit 3. Figure 3 As shown, the fixing seat 1 is provided with at least two first limiting portions 11, and the mounting seat 4 is provided with a first matching portion 41, and the first matching portion 41 is used to match with the first limiting portion 11. When in the first position, the first limiting portion 11 matches with the first matching portion 41 to limit the movement of the mounting seat 4 relative to the fixing seat 1. When in the second position, the monitoring unit 3 is installed to the mounting seat 4. Before the monitoring unit 3 reaches the second position, the first limiting portion 11 can prevent the mounting seat 4 from moving relative to the fixing seat 1, that is, before the monitoring unit 3 is installed on the mounting seat 4, the first limiting portion 11 can be in a matching state with the first matching portion 41, so as to limit the relative movement between the mounting seat 4 and the fixing seat 1.

[0056] In the solution provided in the embodiment of the present application, the limiting cooperation of the first limiting portion 11 and the first matching portion 41 can limit the relative position between the mounting base 4 and the fixed base 1 during the installation of the monitoring unit 3 to the mounting base 4, thereby reducing the possibility of displacement of the mounting base 4 relative to the fixed base 1 during the installation of the monitoring unit 3, and avoiding relative movement of the fixed base 1 and the mounting base 4 before the monitoring unit 3 is installed in place, resulting in failure of the installation of the monitoring unit 3, which is beneficial to improving the success rate of implantation of the monitoring unit 3.

[0057] Since the monitoring unit 3 needs to be implanted in the body, the skin will be pierced during the implantation process. Therefore, when the mounting seat 4 shakes during the implantation process, the monitoring unit 3 will also shake, which can easily lead to a larger wound area on the human body, increased pain and bleeding, and reduced user experience. In the solution provided in the embodiment of the present application, before the monitoring unit 3 is installed on the mounting seat 4, the first limiting portion 11 and the first matching portion 41 can always be in a matching state, thereby limiting the mounting seat 4 and reducing the possibility of the mounting seat 4 shaking. The possibility of the mounting seat 4 shaking during the implantation process can be reduced, which can help reduce the wound area, reduce the pain and the amount of bleeding during the implantation process, and help improve the user experience, which is more in line with actual usage needs.

[0058] The mounting seat 4 can be set on the skin surface and fixed relative to the skin by bonding or other means, so as to prevent the mounting seat 4 and the monitoring unit 3 installed on the mounting seat 4 from falling off from the human body. In the second position, the monitoring unit 3 has been installed on the mounting seat 4, and the implantation process has ended. After the implantation is completed, the fixing seat 1 needs to be separated from the mounting seat 4. At this time, the first limiting portion 11 can be in a state of complete disengagement from the mounting seat 4, or in a state of partial disengagement. When the first limiting portion 11 is completely disengaged from the mounting seat 4, it can be considered that the force between the first limiting portion 11 and the mounting seat 4 is zero, and there is adhesion between the mounting seat 4 and the skin, so that when separating the fixing seat 1 from the mounting seat 4, only the fixing seat 1 can be removed, so that the mounting seat 4 and the monitoring unit 3 installed on the mounting seat 4 remain in the human body. When the first limiting portion 11 is partially released from the mounting seat 4, there is still a certain force between the first limiting portion 11 and the mounting seat 4, which is used to limit the separation of the fixing seat 1 from the mounting seat 4, and the user needs to apply an external force to the fixing seat 1 to overcome the force between the fixing seat 1 and the mounting seat 4 and remove the fixing seat 1. In the second position, the force between the fixing seat 1 and the mounting seat 4 in the solution provided in the embodiment of the present application is less than the adhesion between the mounting seat 4 and the skin, which can reduce the possibility of driving the mounting seat 4 off the skin during the process of removing the fixing seat 1.

[0059] In a possible embodiment, in the second position, at least a portion of the first limiting portion 11 is disengaged from the first matching portion 41, so that after the monitoring unit 3 is installed in place, the fixing base 1 and other structures can be removed, leaving the mounting base 4 and the monitoring unit 3 on the human body.

[0060] In the second position, the first limiting portion 11 can be completely disengaged from the first matching portion 41 to facilitate separation of the fixing seat 1 and the mounting seat 4, which is convenient for user operation. The first limiting portion 11 can also be partially disengaged and partially matched with the first matching portion 41 to maintain a certain limiting relationship between the fixing seat 1 and the mounting seat 4, thereby reducing the possibility of relative movement between the fixing seat 1 and the mounting seat 4 before the user removes the fixing seat 1. When the user thinks it is necessary to remove the fixing seat 1, the fixing seat 1 is separated from the mounting seat 4 by applying external force. Moreover, since there is still a certain degree of matching between the first limiting portion 11 and the first matching portion 41 after the monitoring unit 3 is installed in place, the stability of the mounting seat 4 can be further improved, which is conducive to reducing the possibility of shaking, displacement, etc. of the mounting seat 4 before the monitoring unit 3 is installed in place.

[0061] like Figure 3 As shown, in a possible embodiment, the first limiting portion 11 includes a first limiting section 111 and a second limiting section 112 connected to each other, and the angle between the first limiting section 111 and the second limiting section 112 is an obtuse angle. When the monitoring unit 3 has not reached the second position, the first limiting section 111 cooperates with the first limiting portion 11 in a limiting manner. When the monitoring unit 3 reaches the second position, the second limiting section 112 cooperates with the first limiting portion 11 in a limiting manner.

[0062] The first limiting section 111 and the second limiting section 112 can cooperate with the first limiting portion 11 at different stages, so as to change the matching state of the first limiting portion 11 and the first matching portion 41. The angle between the first limiting section 111 and the second limiting section 112 can make the state of the first limiting section 111 when cooperating with the first matching portion 41 different from the state of the second limiting section 112 when cooperating with the first matching portion 41, including but not limited to different contact areas during cooperation (different increase in stress). By changing the matching state between the first limiting section 11 and the first matching portion 41, the fixing seat 1 can limit the mounting seat 4 to different degrees. Before the monitoring unit 3 is installed on the mounting seat 4, the first limiting section 11 has a greater restriction on the mounting seat 4 to prevent the mounting seat 4 from shaking, trembling, etc. during the installation of the monitoring unit 3, resulting in displacement of the mounting seat 4 and affecting the implantation success rate of the monitoring unit 3. After the monitoring unit 3 is installed on the mounting base 4, the first limiting portion 11 partially releases the restriction on the mounting base 4, thereby reducing the difficulty for the user to remove the fixing base 1 after the implantation is completed, which can save more effort and facilitate operation.

[0063] like Figure 4As shown, in a possible embodiment, the first limiting section 111 includes a first abutting surface 111a, and the second limiting section 112 includes a second abutting surface 112a. The angle between the first abutting surface 111a and the second abutting surface 112a is an acute angle, and the angle between the first abutting surface 111a and the second abutting surface 112a is α, and 0°<α<90°, that is, the first abutting surface 111a and the second abutting surface 112a are not parallel to each other or perpendicular to each other. In the direction away from the first abutting surface 111a, the second abutting surface 112a can be inclined in the direction away from the implant unit 2. The first matching portion 41 includes a third abutting surface 411. As shown Figure 4 As shown, when the monitoring unit 3 is in the first position, the first abutting surface 111a and the third abutting surface 411 abut against each other; Figure 5 As shown, when the monitoring unit 3 is in the second position, the second abutting surface 112a abuts against the third abutting surface 411.

[0064] Since the angles of the first abutting surface 111a and the second abutting surface 112a are different, the contact area when the first abutting surface 111a and the third abutting surface 411 cooperate is different from the contact area when the second abutting surface 112a and the third abutting surface 411 cooperate, so that the cooperation state of the first limiting portion 11 and the first matching portion 41 is different. When the cooperation state of the first limiting portion 11 and the second limiting portion 212 is different, the restriction of the first limiting portion 11 on the mounting seat 4 is different. Before the monitoring unit 3 is installed in place, the first limiting portion 11 has a greater restriction on the mounting seat 4 to limit the relative movement between the mounting seat 4 and the fixing seat 1, which is conducive to improving the success rate of the implantation of the monitoring unit 3. After the monitoring unit 3 is installed in place, the first limiting portion 11 has a smaller restriction on the mounting seat 4, which can facilitate the user to separate the fixing seat 1 from the mounting seat 4, and the operation is simpler and more labor-saving.

[0065] like Figure 6 and Figure 7As shown, in a possible implementation, when the monitoring unit 3 is located at the first position, the first limiting portion 11 abuts against the third abutting surface 411 through the first abutting surface 111a, and at this time, the first abutting surface 111a and the third abutting surface 411 are in a parallel state, and the contact area between the two is relatively large. There may be an angle between the first abutting surface 111a and the third abutting surface 411 and the first direction, and the angle is related to the implantation angle of the online blood glucose monitoring device. Usually, the angle between the first abutting surface 111a and the third abutting surface 411 and the first direction may be the same as the implantation angle, or may float within a certain range relative to the implantation angle. Usually, the first abutting surface 111a and the third abutting surface 411 may be parallel to the top surface of the mounting seat 4, and the top surface of the mounting seat 4 is the surface of the mounting seat 4 away from the human body. Such a design can be used to limit the movement of the fixing base 1 relative to the mounting base 4 to the side away from the human body when the first abutting surface 111a and the third abutting surface 411 cooperate, thereby preventing the fixing base 1 and the mounting base 4 from having relative movement before the monitoring unit 3 is installed in place, and further preventing the fixing base 1 from being separated from the mounting base 4. When the monitoring unit 3 is located in the second position, the first limiting portion 11 contacts the third abutting surface 411 through the second abutting surface 112a. At this time, the second abutting surface 112a is not parallel to the third abutting surface 411, and the second abutting surface 112a is inclined relative to the third abutting surface 411. The contact area between the second abutting surface 112a and the third abutting surface 411 is small. In a possible embodiment, along the first direction, the second abutting surface 112a gradually inclines toward the direction close to the inside of the fixing base 1. The second abutting surface 112a can be used to form an inclined guide surface. When the second abutting surface 112a is matched with the first matching portion 41, the first matching portion 41 can slide along the second abutting surface 112a relative to the first limiting portion 11, so that the first limiting portion 11 and the first matching portion 41 are released from the matching. Since the contact area between the first limiting portion 11 and the third abutting surface 411 is different when the monitoring unit 3 is in different positions, the restriction of the first limiting portion 11 on the mounting seat 4 is also different. Before the monitoring unit 3 is installed on the mounting seat 4, the contact area between the first limiting portion 11 and the mounting seat 4 can be greater than the contact area between the first limiting portion 11 and the mounting seat 4 after the monitoring unit 3 is installed on the mounting seat 4, thereby reducing the shaking of the mounting seat 4 relative to the fixing seat 1 before the monitoring unit 3 is installed in place, thereby improving the success rate of implantation of the monitoring unit 3, and helping to reduce the wound area, reduce pain, and enhance the user experience.

[0066] In a possible implementation, the first limiting section 111 includes a first abutting surface 111a, the second limiting section 112 includes a second abutting surface 112a, the first matching portion 41 includes a third abutting surface 411 and a fourth abutting surface 412, when the monitoring unit 3 is in the first position, the first abutting surface 111a abuts against the third abutting surface 411, and the first abutting surface 111a can be parallel to the third abutting surface 411, when the monitoring unit 3 is in the second position, the second abutting surface 112a and the fourth abutting surface 412 are in contact with each other. 2, the second abutting surface 112a can be parallel to the fourth abutting surface 412. In order to facilitate the separation of the fixing base 1 and the mounting base 4 after the monitoring unit 3 is installed, the second abutting surface 112a and the fourth abutting surface 412 can be used to form a guide surface. The second abutting surface 112a and the fourth abutting surface 412 can be inclined relative to the movement direction when the fixing base 1 is removed. When the fixing base 1 is removed, the second abutting surface 112a and the fourth abutting surface 412 can slide relative to each other, so as to facilitate the separation of the fixing base 1 and the mounting base 4.

[0067] like Figure 2 As shown, in a possible embodiment, the fixing base 1 also includes a mounting wall and a connecting arm 113 connected to the mounting wall and the first limiting portion 11, the mounting wall may be an inner wall of the fixing base 1, and the angle between the extension direction of the connecting arm 113 and the first direction is an acute angle.

[0068] The connecting arm 113 may be a structure such as an elastic arm. By providing the elastic arm, the position of the first limiting portion 11 can be adjusted. By changing the structure of the connecting arm 113 and the angle between the connecting arm 113 and the first direction, the position of the first limiting portion 11 can be adjusted, making the setting position of the first limiting portion 11 more flexible, which is conducive to optimizing the internal structure of the online blood glucose monitoring device and making the overall structure more compact. At the same time, the first limiting portion 11 can be driven to move relative to the first matching portion 41 by driving the connecting arm 113, which is conducive to reducing the volume of the first limiting portion 11 and facilitating driving the first limiting portion 11.

[0069] In a possible embodiment, the angle between the connecting arm 113 and the first direction is 15° to 45°. The angle between the connecting arm 113 and the first direction can be set according to actual needs, including but not limited to 15°, 17°, 19°, 21°, 23°, 25°, 27°, 29°, 31°, 33°, 35°, 37°, 39°, 41°, 43°, 45°, etc.

[0070] When the angle between the connecting arm 113 and the first direction is too large, it is laborious to drive the connecting arm 113 to drive the first limiting part 11 to release the match with the first matching part 41. When the angle between the connecting arm 113 and the first direction is too small, it is easy to reduce the matching stability of the first limiting part 11 and the first matching part 41, and it is easy to cause the first limiting part 11 and the first matching part 41 to release the match in advance, resulting in the release of the limiting match between the mounting seat 4 and the fixing seat 1 before the monitoring unit 3 reaches the second position, which can cause relative positions and implantation failure. Therefore, the angle between the connecting arm 113 and the first direction can be set to 15° to 45°. Considering the structure, size and other factors of the online blood glucose monitoring device, the angle between the connecting arm 113 and the first direction can be set to 15° to 23°, so that the first limiting part 11 can be stably matched with the first matching part 41, and it is also easy to drive the connecting arm 113 to drive the first limiting part 11 to move relative to the first matching part 41 to release the limit. Such a design not only saves effort and is more convenient to operate, but also makes the structure of the online blood glucose monitoring device more compact, which is conducive to miniaturized design.

[0071] like Figure 8 As shown, in a possible embodiment, the implant unit 2 includes an abutment portion 211. When in the first position, the abutment portion 211 and the connecting arm 113 are spaced apart, and a spacing is provided between the abutment portion 211 and the connecting arm 113 along the first direction. When the implant unit 2 moves along the first direction, the abutment portion 211 can move to abut against the connecting arm 113, so as to drive the connecting arm 113 to move or deform in a direction gradually away from the first matching portion 41, thereby driving the first limiting portion 11 to gradually disengage from the first matching portion 41.

[0072] By setting the abutment portion 211 and the connecting arm 113 at intervals, after the implant unit 2 moves a certain distance relative to the fixing seat 1, it can contact the connecting arm 113 and drive the connecting arm 113 to drive the first limiting portion 11 to move, so that the delayed driving of the connecting arm 113 can be realized through the mechanical structure, that is, after a period of time after the implantation action begins, the first limiting portion 11 gradually starts to disengage from the first matching portion 41. Such a design can make the implantation action and the disengagement of the first limiting portion 11 and the first matching portion 41 start asynchronously, and by delaying the driving of the first limiting portion 11 to disengage from the first matching portion 41, the possibility of disengagement between the fixing seat 1 and the mounting seat 4 before the monitoring unit 3 is installed in place can be reduced, thereby reducing the possibility of shaking, displacement, etc. of the mounting seat 4 due to the early release of the limit of the mounting seat 4, thereby improving the implantation success rate of the monitoring unit 3, which is conducive to reducing the wound area, reducing the pain and bleeding, and improving the user experience.

[0073] like Figure 8 As shown, in a possible embodiment, the implant unit 2 includes an auxiliary needle assembly 21 and a first driving member 5, the auxiliary needle assembly 21 includes at least one second limiting portion 212, and the fixed seat 1 includes at least one second matching portion 12, and the matching of the second limiting portion 212 and the second matching portion 12 can be used to limit the movement of the auxiliary needle assembly 21 relative to the fixed seat 1. The second limiting portion 212 can move or deform relative to the fixed seat 1 to release the matching with the second matching portion 12, so that the auxiliary needle assembly 21 can move relative to the fixed seat 1, so that the implant unit 2 can move relative to the fixed seat 1 and perform the implantation action.

[0074] By setting the second limiting portion 212 and the second matching portion 12, the movement of the implant unit 2 can be controlled, so that the implantation action can be controlled. When the implantation action needs to be performed, the limitation on the implant unit 2 can be released by releasing the cooperation between the second limiting portion 212 and the second matching portion 12, so that the implant unit 2 can move along the first direction to perform the implantation action.

[0075] In a possible embodiment, the first driving member 5 can be an elastic member such as a spring. Before the second limiting portion 212 is disengaged from the second matching portion 12, the first driving member 5 can be in a deformed state. After the first limiting portion 11 is disengaged from the second matching portion 12, the restoring force of the first driving member 5 acts on the implant unit 2 to drive the implant unit 2 to move in the first direction.

[0076] The implant unit 2 and the fixing seat 1 are limited by the cooperation between the second limiting portion 212 and the second matching portion 12, and the cooperation between the fixing seat 1 and the mounting seat 4 is limited by the cooperation between the first limiting portion 11 and the first matching portion 41. When the implantation action needs to be performed, the cooperation between the second limiting portion 212 and the second matching portion 12 is released so that the implant unit 2 can move in the first direction for performing the implantation action. When the implant unit 2 moves to the point where the abutment portion 211 contacts the connecting arm 113, the implant unit 2 continues to move in the first direction, thereby driving the connecting arm 113 to swing to drive the first limiting portion 11 to move in the direction away from the first matching portion 41. That is, in the solution provided in the embodiment of the present application, the limiting of the implant unit 2 and the limiting of the mounting seat 4 are not released at the same time. When the second limiting portion 212 and the second matching portion 12 are released, the first limiting portion 11 and the first limiting portion 11 will not be released simultaneously or directly. The implant unit 2 needs to move until the abutting portion 211 contacts the connecting arm 113 before the first limiting portion 11 and the first matching portion 41 begin to be released.

[0077] Such a design can avoid releasing the limit of the mounting seat 4 while releasing the limit of the implant unit 2. Therefore, during the implantation process, the relative position between the mounting seat 4 and the fixed seat 1 can still be limited by the cooperation of the first limiting portion 11 and the first matching portion 41, thereby reducing the possibility of shaking of the mounting seat 4 during the implantation process, which is beneficial to improving the success rate of implantation and is more in line with actual usage needs.

[0078] The state after the second limiting portion 212 and the second matching portion 12 are unlocked is as follows: Fig. 9 As shown, when the implant unit 2 drives the monitoring unit 3 to move to the second position, the state of the online blood glucose monitoring device is as follows: Fig.10 shown.

[0079] like Fig.11 , Fig.12 and Fig.13 As shown, in a possible embodiment, the implant unit 2 further includes a puncture assembly 22 and a second driving member 23, and the puncture assembly 22 can be a half-wall needle assembly, etc. The auxiliary needle assembly 21 includes a third limiting portion 213, and the puncture assembly 22 includes a third matching portion 221. The third limiting portion 213 and the third matching portion 221 cooperate to limit the movement of the puncture assembly 22 relative to the auxiliary needle assembly 21 along the second direction. The first direction is opposite to the second direction. Generally, the first direction is a direction close to the human body, and the second direction is a direction away from the human body.

[0080] When performing the implantation action, the third limiting portion 213 cooperates with the third matching portion 221 to limit the relative movement between the puncture assembly 22 and the auxiliary needle assembly 21, so that the puncture assembly 22 can move along the first direction with the auxiliary needle assembly 21 to perform the implantation action. The puncture assembly 22 is used to pierce the skin so that the electrodes of the monitoring unit 3 can be implanted inside the human body. After the monitoring unit 3 reaches the second position, that is, after the monitoring unit 3 is installed in place, the third limiting portion 213 can be released from the third matching portion 221, so that the second driving member 23 can drive the puncture assembly 22 to move in the second direction opposite to the first direction, that is, after the implantation is completed, the puncture assembly 22 is withdrawn in the direction away from the human body.

[0081] like Fig.11 , Fig.12 and Fig.13 As shown, in a possible embodiment, the fixing seat 1 includes a fourth matching portion 13. When the implant unit 2 moves along the first direction, the fourth matching portion 13 abuts against the third limiting portion 213 to limit the third limiting portion 213 from being disengaged from the third matching portion 221.

[0082] The fourth matching portion 13 may be located on a side of the third limiting portion 213 away from the third matching portion 221, and is used to limit the movement of the third limiting portion 213 in a direction away from the third matching portion 221, thereby limiting the third limiting portion 213 from being disengaged from the third matching portion 221. When the monitoring unit 3 is in the first position and moves from the first position to the second position, the fourth matching portion 13 abuts against the third limiting portion 213. When the monitoring unit 3 is in the second position, the installation of the monitoring unit 3 is completed, and the implant assembly moves until the fourth matching portion 13 disengages from the third limiting portion 213, and the third limiting portion 213 disengages from the third matching portion 221, so that the puncture assembly 22 can move relative to the auxiliary needle assembly 21 in the second direction to achieve the needle withdrawal action.

[0083] Through such a design, the positional relationship between the various components can be utilized to control the implantation action and needle withdrawal action through the mechanical structure, thereby realizing automatic needle withdrawal. When in use, the operation is simple, the difficulty is low, and it is more convenient for users to use.

[0084] The second driving member 23 may be an elastic member such as a spring, one end of which is connected to the needle-assisting assembly 21, and the other end of which is connected to the puncture assembly 22. The third limiting portion 213 may be a structure such as an elastic arm. Before the third limiting portion 213 is released from the third matching portion 221, the third limiting portion 213 may be deformed so that the third limiting portion 213 is matched with the third matching portion 221, and the second driving member 23 may be in a deformed state. The puncture assembly 22 can move along the first direction with the auxiliary needle assembly 21, so as to pierce the skin and enable the electrode of the monitoring unit 3 to be implanted in the human body. After the monitoring unit 3 is installed, the fourth matching part 13 and the third limiting part 213 are released from the abutment relationship. At this time, the third limiting part 213 can restore the deformation and release the limit with the third matching part 221, thereby releasing the limit between the auxiliary needle assembly 21 and the puncture assembly 22. The restoring force of the second driving member 23 can act on the puncture assembly 22 to drive the puncture assembly 22 to move along the second direction relative to the auxiliary needle assembly 21, thereby realizing the needle withdrawal action.

[0085] like Fig.11 , Fig.12 and Fig.13 As shown, in a possible embodiment, the auxiliary needle assembly 21 includes a fourth limiting portion 214, the fourth limiting portion 214 protrudes in a direction close to the fixing seat 1, the fourth matching portion 13 protrudes in a direction close to the auxiliary needle assembly 21, and the fourth limiting portion 214 is used to cooperate with the fourth limiting matching portion to limit the movement distance of the implant unit 2 along the first direction.

[0086] When the monitoring unit 3 is located in the first position, there is a distance between the fourth limiting portion 214 and the fourth matching portion 13 along the first direction. As the implant unit 2 moves along the first direction, the distance between the fourth limiting portion 214 and the fourth matching portion 13 gradually decreases. When the monitoring unit 3 is located in the second position, the fourth limiting portion 214 abuts against the fourth matching portion 13 along the first direction, which is used to limit the implant unit 2 from continuing to move along the first direction, thereby being able to control the movement distance of the implant unit 2 during the implantation action, so that the implant unit 2 drives the monitoring unit 3 to move within a predetermined movement range, preventing the implant unit 2 from moving too far in the first direction, which may lead to the possibility of failure in the installation of the monitoring unit 3. At the same time, it is also possible to control the distance that the puncture component 22 penetrates into the body, thereby preventing the puncture component 22 from penetrating into the body too far, which may increase the pain and affect the user's experience.

[0087] like Figure 8 , Fig. 9 and Fig.10 As shown, in a possible embodiment, the online blood glucose monitoring device also includes a trigger member 7, and the fixed seat 1 is also provided with an avoidance space. The trigger member 7 passes through the avoidance space to press the second limiting portion 212 to drive the second limiting portion 212 to move or deform relative to the fixed seat 1 to release the matching relationship between the second limiting portion 212 and the second matching portion 12. During the movement of the trigger member 7, the trigger member 7 does not drive the first limiting portion 11 to move relative to the first matching portion 41, that is, the trigger member 7 is not used to control the first limiting portion 11 and the first matching portion 41.

[0088] Such a design can release the limit of the implant unit 2 without simultaneously unlocking the limit of the mounting base 4, thereby reducing the possibility of relative movement between the mounting base 4 and the fixing base 1 during the implantation process, which may lead to implantation failure of the monitoring unit 3 and is more in line with actual usage requirements.

[0089] like Figure 2 As shown, in a possible implementation, the online blood glucose monitoring device includes a locking member 6, and the locking member 6 is used to limit the trigger member 7 from pressing the second limiting portion 212. When the locking member 6 is in a locked state, the trigger member 7 cannot drive the second limiting portion 212 to disengage from the second matching portion 12. When the locking member 6 is in an unlocked state, the trigger member 7 can be used to press the second limiting portion 212, driving the second limiting portion 212 to disengage from the second matching portion 12.

[0090] The online blood glucose monitoring device includes a puncture component 22 for piercing the skin. The puncture component 22 is relatively sharp and there is a certain degree of danger. By setting a locking member 6, the possibility of accidental touch of the online blood glucose monitoring device can be reduced. It needs to be unlocked before use, which can reduce the possibility of the puncture component 22 popping out due to misoperation, thereby helping to improve the safety of the online blood glucose monitoring device and better meet actual usage needs.

[0091] like Fig.14 As shown, in a possible embodiment, the locking member 6 includes a main body 61, a first extension portion 62, and a second extension portion 63. The first extension portion 62 and the second extension portion 63 are respectively connected to the main body 61, and the second extension portion 63 can move or deform relative to the main body 61. When the locking member 6 is in a locked state, the first extension portion 62 is located between the trigger member 7 and the second limiting portion 212. At this time, when the trigger member 7 is pressed, the trigger member 7 will abut against the first extension portion 62, and the second limiting portion 212 cannot be driven to disengage from the second matching portion 12. The first extension portion 62 may include a limiting groove 621, such as Fig.15 As shown, when the locking member 6 is in the locked state, at least part of the trigger member 7 is located in the limiting groove 621. The limiting groove 621 can improve the matching accuracy between the first extension portion 62 and the trigger member 7. When the locking member 6 is in the unlocked state, the second extension portion 63 is located between the trigger member 7 and the second limiting portion 212. At this time, the trigger member 7 is pressed, and the trigger member 7 can abut against the second extension portion 63 and drive the second extension portion 63 to move or deform in the direction close to the second limiting portion 212, so that the second extension portion 63 can drive the second limiting portion 212 to move, so that the second limiting portion 212 is released from the second matching portion 12, the limit of the implant unit 2 is released, and the implantation action is started. Such a design can drive the second limiting portion 212 through the second extension portion 63, and use the second extension portion 63 to transmit the movement, so as to reduce the movement distance and size of the trigger member 7.

[0092] like Fig.11 As shown, in a possible embodiment, the mounting base 4 includes a main body 42 and a fifth limiting portion 43, the fifth limiting portion 43 can swing relative to the main body 42, the monitoring unit 3 includes a fifth matching portion 31, and the fifth limiting portion 43 and the fifth matching portion 31 cooperate to limit the monitoring unit 3 from detaching from the mounting base 4.

[0093] During the process of installing the monitoring unit 3 on the mounting base 4 and the process of the monitoring unit 3 moving along the first direction, the fifth matching portion 31 can abut against the fifth matching portion 31 and drive the fifth limiting portion 43 to swing, so that the fifth limiting portion 43 avoids the monitoring unit 3 during the installation of the monitoring unit 3 so that the monitoring unit 3 can pass over the fifth fiber cloth. After the installation of the monitoring unit 3 is completed, the fifth limiting portion 43 can be reset to cooperate with the fifth matching portion 31 to limit the monitoring unit 3 from being separated from the mounting base 4, so as to improve the stability of the installation of the monitoring unit 3.

[0094] In a possible implementation, the monitoring unit 3 may include electrodes, but does not include at least one of a battery module, a data processing module, and a data transmission module. After the monitoring unit 3 is implanted in the body, the needle is withdrawn, and after the needle is withdrawn, the fixing seat 1 may be removed, and the mounting seat 4 and the monitoring unit 3 remain in the human body, and then the electronic unit having the battery module and the data processing module is installed on the mounting seat 4.

[0095] By separately arranging the electronic unit, the volume of the monitoring unit 3 and the mounting base 4 can be reduced, thereby reducing the overall volume of the online blood glucose monitoring device.

[0096] Based on the online blood glucose monitoring device provided in the above embodiments, the embodiment of the present application further provides a method for using the online blood glucose monitoring device, which can be applied to the online blood glucose monitoring device involved in any of the above embodiments. The method for using includes:

[0097] The implant unit 2 drives the monitoring unit 3 to move relative to the fixing seat 1 from the first position along the first direction. In the first position, the first limiting portion 11 of the fixing seat 1 cooperates with the first matching portion 41 of the mounting seat 4 to prevent the mounting seat 4 from moving relative to the fixing seat 1.

[0098] The implant unit 2 drives the first limiting portion 11, so that the first limiting portion 11 gradually moves or deforms in a direction away from the first matching portion 41;

[0099] The implant unit 2 reaches the second position, and the monitoring unit 3 is mounted to the mounting seat 4. In the second position, the first limiting portion 11 and the first matching portion 41 are at least partially released from the matching relationship.

[0100] The implant unit 2 drives the monitoring unit 3 to move along the first direction relative to the fixing seat 1 to perform the implantation action. The puncture assembly 22 of the implant unit 2 is used to pierce the human body so that the electrode of the monitoring unit 3 can enter the body along the wound, so that blood sugar can be monitored. During the movement of the implant unit 2, the implant unit 2 drives the first limiting portion 11 to move or deform to release the matching relationship between the first limiting portion 11 and the first matching portion 41. When the implant unit 2 reaches the second position, the implantation of the monitoring unit 3 is completed. At this time, the monitoring unit 3 is installed on the mounting seat 4, and the first limiting portion 11 and the first matching portion 41 at least partially release the matching relationship. Since the monitoring unit 3 has been implanted, the restriction on the relative position between the mounting seat 4 and the fixing seat 1 can be released, so that it is easy to separate the fixing seat 1 and the mounting seat 4 for easy use.

[0101] In a possible implementation, when the implant unit 2 reaches the second position, the monitoring unit 3 is mounted to the mounting seat 4, and at the second position, the step of at least partially releasing the mating relationship between the first limiting portion 11 and the first mating portion 41 includes:

[0102] In the second position, the first limiting portion 11 and the first matching portion 41 are completely released from the matching relationship.

[0103] In the second position, the monitoring unit 3 has been installed on the mounting seat 4. At this time, the implant unit 2, the fixing seat 1 and other structures used for implantation can be removed. By completely releasing the mating relationship between the first limiting portion 11 and the first matching portion 41, the resistance when removing the implant unit 2, the fixing seat 1 and other structures can be reduced, thereby facilitating use.

[0104] In a possible implementation, the method of use further includes:

[0105] The trigger member 7 drives the second limiting portion 212 to move or deform, so that the second limiting portion 212 and the engaging portion are released from engagement, and the implant unit 2 drives the monitoring unit 3 to move along the first direction.

[0106] The second limiting portion 212 located at the implant unit 2 and the second matching portion 12 located at the avoidance space of the fixed seat 1 are used to limit the relative movement between the implant unit 2 and the fixed seat 1, and the trigger member 7 is used to drive the second limiting portion 212 and the second matching portion 12 to release the matching, so as to release the restriction on the implant unit 2 and perform the implantation action.

[0107] When the implant unit 2 drives the monitoring unit 3 to move in the first direction, the fifth matching portion 31 drives the fifth limiting portion 43 to move or deform. When the monitoring unit 3 reaches the second position, the fifth limiting portion 43 resets and cooperates with the fifth matching portion 31 to prevent the monitoring unit 3 from leaving the mounting seat 4.

[0108] The cooperation between the fifth limiting portion 43 and the fifth matching portion 31 is used to improve the installation stability of the monitoring unit 3 and reduce the possibility of the monitoring unit 3 being separated from the mounting seat 4.

[0109] In a possible implementation, the method of use further includes: removing the implant unit 2 and installing the electronic unit on the mounting seat 4.

[0110] The online blood glucose monitoring device may include an electronic unit, which may include at least one of a battery module, a data processing module and a data transmission module, and may be used in conjunction with the monitoring unit 3. In the monitoring unit 3 and the electronic unit, the battery module, the data processing module and the data transmission module may not be repeatedly set, that is, in the monitoring unit 3 and the electronic unit, a battery module, a data processing module and a data transmission module are included in total to reduce the number of overall components, thereby facilitating miniaturization design. The battery module may include one or more batteries. After the monitoring unit 3 is implanted, the implant unit 2 is removed, and the monitoring unit 3 for monitoring user indicators is set on the human body with the mounting seat 4. The electronic unit can be used to provide energy, and at the same time collect and / or organize the data collected by the monitoring unit 3, and transmit the data to electronic devices such as mobile phones and tablets through signals such as Bluetooth and WiFi, so that users can understand their health status in a timely manner, which is more in line with actual usage needs.

[0111] When in use, the online blood glucose monitoring device is placed at a predetermined implantation position, so that one side of the mounting seat 4 is in contact with the skin, the locking member 6 is unlocked, and then the trigger member 7 is driven to move. The trigger member 7 drives the second extension portion 63 of the locking member 6 to move in a direction close to the second limiting portion 212, so that the second limiting portion 212 and the second matching portion 12 are released from the matching. Before the second limiting portion 212 and the second matching portion 12 are released from the matching, the first driving member 5 can be in a deformed state. After the second limiting portion 212 and the second matching portion 12 are released from the matching, the restoring force of the first driving member 5 can act on the auxiliary needle assembly 21 to drive the auxiliary needle assembly 21 to drive the puncture assembly 22 and the monitoring unit 3 to move in the first direction. When the implant unit 2 moves in the first direction until the abutting portion 211 abuts against the connecting arm 113, the implant unit 2 continues to move in the first direction, and in the process of movement, the connecting arm 113 drives the first limiting portion 11 to move in a direction away from the first matching portion 41 so that the first limiting segment 111 is released from the first matching. During the movement of the implant unit 2 in the first direction, the puncture assembly 22 can extend relative to the online blood glucose monitoring device to puncture the skin, and the electrode of the monitoring unit 3 can extend into the user's body along with the puncture assembly 22. When the implant unit 2 moves to the fourth limiting portion 214 and abuts against the fourth matching portion 13 in the first direction, the implant unit 2 drives the monitoring unit 3 to move to the second position, at which time the monitoring unit 3 is installed on the mounting seat 4. The third limiting portion 213 of the auxiliary needle assembly 21 is released from abutment with the fourth matching portion 13, and the third limiting portion 213 can move in a direction away from the third matching portion 221 of the puncture assembly 22 to release the matching with the third matching portion 221, thereby releasing the limit between the auxiliary needle assembly 21 and the puncture assembly 22. Before the limit between the auxiliary needle assembly 21 and the puncture assembly 22 is released, the second driving member 23 can be in a deformed state. After the limit between the auxiliary needle assembly 21 and the puncture assembly 22 is released, the restoring force of the second driving member 23 can act on the puncture assembly 22 to drive the puncture assembly 22 to move along the second direction to withdraw the needle, and the electrodes of the monitoring unit 3 remain in the user's body. After the needle is withdrawn, the user can remove the implant unit 2, the fixing seat 1 and other structures, and then install the electronic unit on the mounting seat 4 to facilitate the transmission of the data collected by the monitoring device, so that the user can understand his or her physical condition in real time.

[0112] During the implantation process, the stability of the movement of the implant unit 2 is one of the factors that affect the implantation success rate of the monitoring device and the size of the wound. Fig.16As shown, in a possible embodiment, the online blood glucose monitoring device includes a fixed seat 1 and an implant unit 2, and the implant unit 2 can be slidably installed in the fixed seat 1 and can move relative to the fixed seat 1 along a first direction for performing an implantation action. The fixed seat 1 is provided with a first guide portion 14 extending along the first direction, and the implant unit 2 includes a second guide portion 15 extending along the first direction and a second limiting portion 212 that can elastically abut against the inner wall of the fixed seat 1. During the movement of the implant unit 2 relative to the fixed seat 1, the first guide portion 14 cooperates with the second guide portion 15 to guide the relative movement between the fixed seat 1 and the implant unit 2. At the same time, during the movement of the implant unit 2 relative to the fixed seat 1, the second limiting portion 212 can elastically abut against the inner wall of the fixed seat 1, thereby guiding the movement of the implant unit 2 relative to the fixed seat 1.

[0113] By providing the first guide portion 14 and the second guide portion 15, the stability of the implant unit 2 in movement relative to the fixed seat 1 can be improved. The second limiting portion 212 can be a structure that can undergo elastic deformation, such as an elastic arm, and is used to abut against the inner wall of the fixed seat 1 during movement. Since the second limiting portion 212 elastically abuts against the inner wall of the fixed seat 1, when the implant unit 2 shakes during movement, the second limiting portion 212 will be deformed, thereby changing the interaction force between the second limiting portion 212 and the fixed seat 1, so that the implant unit 2 can move in a direction opposite to the shaking direction, which is conducive to keeping the implant unit 2 stable. Through such a design, the stability of the implant unit 2 in movement relative to the fixed seat 1 can be improved, the possibility of the implant unit 2 shaking relative to the fixed seat 1 can be reduced, which is conducive to reducing the wound area, thereby reducing the amount of bleeding and pain, and is conducive to improving the user experience.

[0114] During the implantation process, when the implant unit 2 has poor movement stability and shakes, it will cause the wound area on the human body to increase, the pain and bleeding volume to increase, and affect the user's experience.

[0115] like Figure 8 , Fig. 9 and Fig.10 As shown, the second limiting portion 212 includes a locking position and an unlocking position. In the locking position, the second limiting portion 212 cooperates with the second matching portion 12 of the fixing seat 1 to prevent the implant unit 2 from moving relative to the fixing seat 1. When the second limiting portion 212 moves or deforms in a direction away from the second matching portion 12, the second limiting portion 212 can switch from the locking position to the unlocking position. In the unlocking position, the implant unit 2 can move relative to the fixing seat 1.

[0116] Through such a design, the second limiting portion 212 can be used to limit the implant unit 2 and also guide the implant unit 2. Before the implantation action begins, the second limiting portion 212 is used to lock the implant unit 2, and after the implantation action begins, the second limiting portion 212 is used to guide the implant unit 2. The second limiting portion 212 can integrate the functions of limiting and guiding at the same time, which is conducive to saving the number of components of the online blood glucose monitoring device, making the overall structure more compact, and facilitating miniaturization design.

[0117] like Fig.17 and Fig.18 As shown, in a possible implementation manner, one of the first guide portion 14 and the second guide portion 15 is a guide protrusion, and the other is a guide recess, and at least a portion of the guide protrusion extends into the guide recess.

[0118] Through such a design, a guide rail and guide groove structure can be formed, which is beneficial to improving the stability of the movement of the implant unit 2 relative to the fixing seat 1 and is more in line with actual usage requirements.

[0119] like Fig.18 As shown, in a possible embodiment, at least one inner side wall of the guide recess is provided with at least two protrusions 215a, and the protrusions 215a are provided in a direction close to the guide protrusion. When the guide protrusion and the guide recess are matched, the protrusions 215a are used to abut against the guide protrusion.
