The embodiments of the present application will be described below with reference to the drawings.

In the description of the embodiments of the present application, it should be noted that the terms "mounted" and "connected" are to be interpreted broadly, unless explicitly stated or limited otherwise, and for example, "connected" may or may not be detachably connected; may be directly connected or indirectly connected through an intermediate. The directional terms used in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are used solely in the direction of reference to the drawings, and thus, are used for better and clearer illustration and understanding of the embodiments of the present application, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the embodiments of the present application. "plurality" means at least two.

It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The embodiment of the application provides a monitoring device. The monitoring device is a wearable monitoring device which can be used for monitoring various biochemical target substances such as blood sugar, lactic acid, uric acid, dissolved oxygen, hydrogen peroxide, ions and the like. The present application is specifically described with an example in which the monitoring device is used to monitor blood glucose.

Referring to fig. 1 and fig. 2A, fig. 1 is a schematic structural diagram of a monitoring device 100 according to an embodiment of the present disclosure. Fig. 2A is an exploded view of the monitoring device 100 shown in fig. 1.

The monitoring apparatus 100 includes a monitoring device 10 and an implanter 20. The monitoring device 10 comprises an analysis sensor, the monitoring device 10 is attached to the skin of a user (usually attached to the skin of the arm or the skin of the abdomen of the user), the analysis sensor is implanted under the skin of the user, and the analysis sensor measures the glucose concentration in the human tissue fluid in real time based on the electrochemical principle to obtain measurement data. The monitoring device 10 generally includes a data transmission module for transmitting the measurement data to a receiver (e.g., a mobile phone, a computer, a watch, a bracelet, or other dedicated device cooperating with the monitoring device 10), and the receiver can display the measurement data. Because the monitoring device 10 is adhered to the skin, the glucose concentration in the human tissue fluid can be continuously monitored in real time for a long time, and the problem of high missed diagnosis rate easily caused by only measuring the fasting blood glucose is avoided.

The implanter 20 is used to assist in the implantation of the analytical sensors of the monitoring device 10 at the location where the user needs to apply the monitoring device 10, i.e., to assist in the implantation of the analytical sensors of the monitoring device 10 into the skin of the user. It will be appreciated that since the analytical sensor is relatively rigid and cannot be inserted into the skin of a person, the implanter 20 is used to assist in the analysis of the sensor to facilitate successful insertion of the analytical sensor into the skin of the user.

Illustratively, the implanter 20 may include a housing 21 and an implantation button 22, and the monitoring device 10 may be housed in the housing 21. When the user needs to attach the monitoring device 10 to the skin of the user, as shown in fig. 2B, the implanter 20 may contact the opening of the housing 21 with the skin of the user, then press the implantation button 22, the implanter 20 pushes the monitoring device 10 to spring toward the skin of the user, so that the monitoring device 10 is attached to the skin of the user, and the analytical sensor is implanted under the skin of the user, and then the implanter 20 is removed from the skin of the user (as shown in fig. 2C).

Referring to fig. 3, 4 and 5, fig. 3 is a schematic structural diagram of the monitoring device 10 of the monitoring apparatus 100 shown in fig. 2A. Fig. 4 isbase:Sub>A schematic sectional view of the monitoring device 10 shown in fig. 3 inbase:Sub>A directionbase:Sub>A-base:Sub>A. Fig. 5 is an exploded view of the monitoring device 10 shown in fig. 4.

The monitoring device 10 includes a housing 11, a circuit board 12, an actuation post 13, an analytical sensor 14, and an adhesive layer 15. The circuit board 12 is accommodated in the housing 11, the housing 11 includes a top wall 111 and a bottom wall 112, and the adhesive layer 15 is connected to a surface of the bottom wall 112 facing away from the top wall 111 for adhering the monitoring device 10 to an application position (skin of a user). The analytical sensor 14 has one end located inside the housing 11 and electrically connected to the circuit board 12 and the other end extending through the bottom wall 112 and protruding with respect to the adhesive layer 15. A first end 131 of the actuating post 13 is located within the housing 11 and is resiliently connected to the top wall 111, and a second end 132 of the actuating post 13 extends beyond the bottom wall 112 and is exposed relative to the adhesive layer 15. The actuating post 13 is capable of moving in a direction toward the circuit board 12, when the second end 132 protrudes relative to the adhesive layer 15 (see fig. 4), the monitoring device 10 is not opened, and when the monitoring device 10 is applied to the skin of a user, the end surface of the second end 132 is flush with the adhesive layer 15 (see fig. 6), and the actuating post 13 opens the monitoring device 10.

It is understood that the end surface of the second end 132 is flush with the adhesive layer 15, which means that the end surface of the second end 132 facing away from the first end 131 is in the same plane as the surface of the adhesive layer 15 facing away from the top wall 111. The end surface of the second end 132 is flush with the adhesive layer 15, and it is also understood that the end surface of the second end 132 facing away from the first end 131 is substantially flush with the surface of the adhesive layer 15 facing away from the top wall 111, that is, the end surface of the second end 132 may slightly protrude from the surface of the adhesive layer 15 facing away from the top wall 111, and the monitoring device 10 can be turned on. Alternatively, the end surface of the second end 132 may be slightly recessed from the surface of the adhesive layer 15 facing away from the top wall 111, and may be capable of opening the monitoring device 10.

It will be appreciated that when the monitoring device 10 is not yet applied to the skin of a user, as shown in fig. 4 and 7, the second end 132 projects relative to the adhesive layer 15 and the electrical circuit of the monitoring device 10 is open and the monitoring device 10 is not open. Referring to fig. 6, when the monitoring device 10 is applied to the skin of the user, since the actuation post 13 is elastically connected to the top wall 111 or the circuit board 12, the second end 132 is subject to the reaction force of the skin, and moves in the direction away from the skin (in the direction of the circuit board 12) until the end surface of the second end 132 is flush with the adhesive layer 15, the actuation post 13 makes the circuit of the monitoring device 10 in a connected state, the monitoring device 10 is turned on, and the analytical sensor 14 of the monitoring device 10 starts to continuously monitor the blood glucose concentration of the user.

In the present embodiment, the activation column 13 is disposed on the monitoring device 10, so that when the monitoring device 10 is attached to the skin of the user, the activation column 13 is subject to the reaction force of the skin, so that the end surface of the second end 132 is flush with the adhesive layer 15, and the monitoring device 10 is opened by the activation column 13. Compare in setting up bluetooth module or network module in monitoring devices 10 to it is more convenient to use operative installations such as cell-phones to realize opening of monitoring devices 10 through wireless or bluetooth mode, need not open with the help of operating equipment, and monitoring devices 10 laminates and just can realize opening in human skin, need not that the user manually realizes the step that monitoring devices 10 opened, improves user and uses experience.

Simultaneously, because monitoring devices 10 in this application do not set up inside bluetooth module or the network module that is used for realizing that monitoring devices 10 opens, can effectively reduce the part of installing on circuit board 12, and circuit design of circuit board 12 is more succinct, and reduce cost and circuit board 12 can be done littleer, are favorable to monitoring devices 10's miniaturization, and monitoring devices 10 is less, brings user's uncomfortable sense still less, and user's wearing experience is better.

It can be understood that, realize opening of monitoring device 10 through wireless or bluetooth mode, before monitoring device 10 has not yet been applied to user's skin (monitoring device 10 leaves the factory after to monitoring device 10 before applying to user's skin), need monitoring device 10 to await the opportune moment under the low-power consumption mode, need more power consumption, in order to guarantee the time of endurance of monitoring device 10, the battery that sets up in monitoring device 10 needs to set up very big, is unfavorable for the miniaturization and the long-time of endurance of monitoring device 10. Monitoring devices 10 in this application realizes monitoring devices 10's mechanical type through setting up the start column 13 and starts, does not need monitoring devices 10 standby before applying in skin, and the battery can be done littleer, is favorable to monitoring devices 10's miniaturization and long-time continuation of the journey.

Of course, in other embodiments, the first end 131 of the actuating post 13 may also be resiliently connected to the circuit board 12. It can be understood that the circuit board 12 is located inside the housing 11, the distance from the circuit board 12 to the bottom wall 112 is smaller than the distance from the top wall 111 to the bottom wall 112, the actuating column 13 is elastically connected to the circuit board 12, and the length of the actuating column 13 is smaller than the length of the actuating column 13 elastically connected to the top wall 111, and in order to ensure that the length of the actuating column 13 meets the requirement, the thickness of the monitoring device 10 needs to be larger, which is not beneficial to the miniaturization of the monitoring device 10. In other words, the actuating post 13 is elastically connected to the top wall 111, which facilitates the thinning of the monitoring device 10.

Of course, in other embodiments, the first end 131 of the actuating post 13 may be resiliently connected to other components besides the circuit board 12 and the top wall, as long as the actuating post 13 is ensured to enable the opening of the monitoring device 10.

In this embodiment, when the second end 132 of the actuating post 13 protrudes relative to the adhesive layer 15, the distance between the protruding surface of the second end 132 relative to the adhesive layer 15 and the adhesive layer 15 is in the range of 1mm to 3mm (including 1mm and 3 mm). Opening of the monitoring device 10 is achieved by limiting the distance between the surface of the second end 132 protruding from the adhesive layer 15 and the adhesive layer 15 to be in the range of 1mm to 3mm (including 1mm and 3 mm) to ensure that the second end 132 of the actuating post 13 contacts the skin of the user before the adhesive layer 15 contacts the skin of the user when the monitoring device 10 is applied to the skin of the user, so that the second end 132 is moved in the direction toward the circuit board 12 by the reaction force of the skin.

Referring to fig. 4 and 5, the housing 11 is circular. The housing 11 includes a first housing 11A and a second housing 11B. The first housing 11A includes a bottom wall 112 and a first peripheral wall 113 disposed around the bottom wall 112, where the bottom wall 112 is the bottom wall 112 of the housing 11, and the adhesive layer 15 is attached to a surface of the bottom wall 112 facing away from the first peripheral wall 113. The second housing 11B includes a top wall 111 and a second peripheral wall 114 disposed around the top wall 111, the top wall 111 is the top wall 111 of the housing 11, and a surface of the second peripheral wall 114 facing away from the top wall 111 is provided with a fitting groove 1141. The second housing 11B covers the first housing 11A, the first peripheral wall 113 is engaged in the engaging groove 1141 of the second peripheral wall 114, and the first peripheral wall 113 can be fixed to the engaging groove 1141 by glue. The first housing 11A and the second housing 11B together enclose a space for accommodating devices such as the circuit board 12.

Of course, in the implementation scenario of other embodiments, the shape of the housing 11 may also be a square, a rectangle, a special shape, a star, a heart, or other shapes. In another implementation scenario of other embodiments, the first shell 11A and the second shell 11B may also be fixed by fixing means such as ultrasonic welding. Of course, in another implementation scenario of other embodiments, the second peripheral wall 114 may not be provided with a matching groove, and the surface of the first peripheral wall facing away from the bottom wall and the surface of the second peripheral wall facing away from the top wall may also be sealed by adhesion.

It can be understood that, in the embodiment, the fitting groove 1141 is formed in the second peripheral wall 114, so that the first peripheral wall 113 of the first housing 11A is engaged with the fitting groove 1141, and the first peripheral wall 113 and the fitting groove 1141 are fixed by the glue, which not only can realize stable fixation of the connection between the first housing 11A and the second housing 11B, but also can fill the gap between the fitting groove 1141 and the first peripheral wall 113 by the glue, thereby ensuring good sealing performance at the connection between the first housing 11A and the second housing 11B. Since the monitoring device 10 needs to continuously monitor the blood glucose concentration of the user for more than ten days, the monitoring device 10 needs to be worn on the skin of the user for more than ten days. By ensuring the sealing property of the first housing 11A and the second housing 11B, the monitoring device 10 is prevented from being damaged by water inflow during bathing, swimming, and the like of the user.

In this embodiment, the first housing 11A and the second housing 11B may be made of plastic such as polycarbonate or acrylonitrile-butadiene-styrene copolymer. The housing 11 in this embodiment is composed of two parts (a first housing 11A and a second housing 11B) to facilitate assembly of the monitoring device 10. Of course, in other embodiments, the specific structure of the first housing 11A and the second housing 11B may also not be limited to the above description, and the present application does not limit this. The shape of the surface of the bottom wall 112 of the first housing 11A facing away from the top wall 111 may also be adapted to the shape of human skin. Or the materials of the first shell 11A and the second shell 11B are soft, so that the unevenness of the skin of the user can be adapted to, and the surface of the monitoring device 10 attached to the skin of the user can be ensured to be bent and attached to the skin of the user.

Referring to fig. 5 and 8, fig. 8 is a schematic structural view of another angle of the first housing 11A in the structure shown in fig. 5.

The bottom wall 112 and the first peripheral wall 113 of the first housing 11A enclose a first space a. The bottom wall 112 may include a through hole 1121 and a receiving enclosure 1122, the through hole 1121 penetrates through two opposite surfaces of the bottom wall 112, and the receiving enclosure 1122 is fixed on the surface of the bottom wall 112 located in the first space a and surrounds the periphery of the through hole 1121. The walls of the receiving walls 1122 and the through holes 1121 together form a space for receiving the actuation post 13, and the second end 132 of the actuation post 13 is exposed to the adhesive layer 15 through the through hole 1121. The walls of the holes that receive the walls 1122 and the holes 1121 also limit the actuation post 13, thereby preventing the actuation post 13 from deflecting during movement.

Of course, in other embodiments, the bottom wall 112 may also include only the through hole 1121, not the receiving enclosure.

In this embodiment, the housing enclosure 1122 may be integrally formed with the bottom wall 112, and the housing enclosure 1122 may be integrally formed with the bottom wall 112 by an injection molding process. The side of the housing enclosure 1122 facing away from the bottom wall 112 is also provided with a notch B for avoiding the actuation post 13, so that the actuation post 13 is not obstructed during the movement. Of course, the housing enclosure 1122 may be fixed to the bottom wall 112 by other connection means such as bonding or screwing.

Bottom wall 112 may also include relief holes 1123, isolation perimeter walls 1124, and confinement perimeter walls 1125. Avoiding hole 1123 penetrates through the two opposite surfaces of bottom wall 112 and is spaced apart from through hole 1121. The isolation enclosure 1124 is fixed on the surface of the bottom wall 112 in the first space a, and surrounds the avoiding hole 1123. Limit fence 1125 is positioned adjacent to and communicates with isolation fence 1124. One end of the analytical sensor 14 is limited in the space formed by the limiting wall 1125 and the bottom wall 112, and the other end of the analytical sensor 14 extends into the isolation wall 1124 and extends out of the bottom wall 112 through the avoiding hole 1123. Isolation enclosure 1124 serves to isolate the other end of analytical sensor 14 from first space a, i.e., to provide isolation between first space a and the interior of isolation enclosure 1124. Of course, in other embodiments, the bottom wall 112 may not include a retaining fence.

Isolation enclosure 1124 and limiting enclosure 1125 may be integrally formed with bottom wall 112, and isolation enclosure 1124 and limiting enclosure 1125 may be integrally formed with bottom wall 112 by an injection molding process. Of course, the isolation perimeter wall 1124 and the limit perimeter wall 1125 may be fixed to the bottom wall 112 by other connection methods such as bonding, screwing, etc.

The bottom wall 112 is further provided with a positioning column 1126, and the positioning column 1126 is used for matching with the second housing 11B to realize the mounting coordination of the first housing 11A and the second housing 11B. In this embodiment, the number of the positioning posts 1126 is two. The positioning posts 1126 may be integrally formed with the bottom wall 112 or may be fixed to the bottom wall 112 by bonding or other connection means. Of course, in other embodiments, there may be other numbers of positioning posts 1126.

Referring to fig. 4, 5 and 9, fig. 9 is a schematic structural view of the second housing 11B of the structure shown in fig. 5 at another angle.

The top wall 111 and the second peripheral wall 114 of the second housing 11B enclose a second space C. The second space C and the first space a together form an inner space of the housing 11. The top wall 111 includes an isolation wall 1111 and an avoiding hole 1112, and the avoiding hole 1112 penetrates through two opposite surfaces of the top wall 111. The isolation wall 1111 is fixed on the surface of the top wall 111 in the second space C and surrounds the periphery of the avoiding hole 1112. When the second housing 11B is fixed to the first housing 11A, the isolation fence 1111 of the second housing 11B is connected to the isolation fence 1124 of the first housing 11A, and the avoiding hole 1112 of the second housing 11B and the avoiding hole 1123 (fig. 8) of the first housing 11A are communicated, so that the implantation assisting device of the implanter 20 sequentially passes through the avoiding hole 1112 and the avoiding hole 1123 to wrap the analytical sensor 14 extending out of the adhesive layer 15, so as to assist the analytical sensor 14 to be implanted under the skin of the user.

Isolation fence 1111 may be formed as an integral structure with top wall 111, and isolation fence 1111 may be formed as an integral structure with top wall 111 through an injection molding process. Of course, the barrier ribs 1111 may be fixed to the top wall 111 by other connection means such as bonding, screwing, etc.

The top wall 111 is further provided with a limiting post 1113, and the limiting post 1113 is used for limiting the circuit board 12, so that the circuit board 12 is stably fixed in the housing 11. One side of the limiting post 1113, which faces away from the top wall 111, is provided with a limiting hole D, the limiting hole D is used for being matched with a positioning post 1126 of the first casing 11A, and the positioning post 1126 is clamped in the limiting hole D of the limiting post 1113 (fig. 4), so as to realize the installation and coordination of the first casing 11A and the second casing 11B. That is, the limiting column 1113 in the present application has two purposes, namely, on one hand, it is used for limiting the circuit board 12, and on the other hand, it is used for realizing the coordination with the first housing 11A.

In this embodiment, the number of the limiting columns 1113 is two. The stopper 1113 may be integrally formed with the top wall 111, or may be fixed to the top wall 111 by bonding or other connection means. Of course, in other embodiments, the number of the limiting columns 1113 can be other. Alternatively, the limiting column 1113 may be used only for limiting the circuit board 12, or the limiting column 1113 may not include the limiting hole D.

Of course, in other embodiments, the manner of engagement between the stop post 1113 and the positioning post 1126 is not limited to the above description.

Referring to fig. 5 and 10, fig. 10 is a schematic view of the circuit board 12 of the structure shown in fig. 5 at another angle.

In this embodiment, the circuit board 12 includes a body 121, and a first conductive sheet 122 and a second conductive sheet 123 provided on the body 121. The first conductive plate 122 and the second conductive plate 123 are configured to cooperate with the actuating post 13 to enable the monitoring device 10 to be turned on and off.

The body 121 includes a positioning hole 124 corresponding to the stopper 1113 and a through hole 125 for avoiding the isolation fence 1111 of the second housing 11B. The limiting posts 1113 of the second housing 11B penetrate through the corresponding positioning holes 124 to achieve the positioning of the circuit board 12. The through hole 125 is used to connect the isolation fence 1111 of the second housing 11B with the isolation fence 1124 of the first housing 11A.

The end of the analytical sensor 14 remote from the adhesive layer 15 is fixed to the body 121 and is electrically connected to the body 121. The main body 121 may include a main circuit for generating blood glucose monitoring data (the main circuit may include an electronic component with a relatively high data processing capability such as a single-chip microcomputer), a switch circuit for triggering the main circuit to be turned on or off, and a data transmission module for transmitting measurement data to a receiver (such as a mobile phone, a computer, a watch, or a bracelet), and the main body 121 may further include a battery (such as a button battery or a rechargeable lithium battery) for supplying power to the main circuit and the switch circuit.

Referring to fig. 10 and 11, fig. 11 is a schematic view showing the structure of the actuating rod 13 and the like in fig. 10.

The body 121 further includes a relief hole 126, and the first end 131 is elastically connected to the top wall 111 through the relief hole 126. Of course, in other embodiments, the body 121 does not include the avoiding hole when the first end 131 is elastically connected to the circuit board 12.

The first conductive plate 122 and the second conductive plate 123 are symmetrically disposed on the body 121 and electrically connected to the switch circuit of the body 121. In this embodiment, the first conductive plate 122 and the second conductive plate 123 both have elasticity, one end of the first conductive plate 122 is fixed to the body 121, the other end of the first conductive plate 122 is matched with the second conductive plate 123 or the starting column 13, one end of the second conductive plate 123 is fixed to the body 121, and the other end of the second conductive plate 123 is matched with the first conductive plate 122 or the starting column 13, so as to open the monitoring device 10.

Referring to fig. 11 and 12, fig. 12 is a schematic structural view of another state of the structure shown in fig. 11. The configuration shown in fig. 11 corresponds to a state in which the monitoring device 10 is not opened, and the configuration shown in fig. 12 corresponds to a state in which the monitoring device 10 is opened.

Specifically, as shown in fig. 11, when the second end 132 of the actuating post 13 protrudes from the adhesive layer 15, the first conductive sheet 122 and the second conductive sheet 123 are separated, the switch circuit of the monitoring device 10 is turned off, and the monitoring device 10 is not turned on. As shown in fig. 12, when the end surface of the second end 132 of the actuating post 13 is flush with the adhesive layer 15, the first conductive sheet 122 and the second conductive sheet 123 are conducted, the switch circuit of the monitoring device 10 is closed, and the monitoring device 10 is opened.

Illustratively, when the second end 132 of the actuating post 13 protrudes relative to the adhesive layer 15, the first conductive sheet 122 and the second conductive sheet 123 are spaced apart by the actuating post 13, the switch circuit of the circuit board 12 is open, and the monitoring device 10 is not turned on. Wherein the actuating post 13 is used to insulate the portion separating the first conductive sheet 122 and the second conductive sheet 123. When the end face of the second end 132 of the starting post 13 is flush with the adhesive layer 15, the starting post 13 moves and is no longer spaced between the first conductive plate 122 and the second conductive plate 123, the first conductive plate 122 and the second conductive plate 123 are in contact conduction under the elastic action, the switching circuit of the circuit board 12 is conducted, and the monitoring device 10 is turned on.

Referring to fig. 13, fig. 13 is a schematic structural diagram of the first conductive sheet 122 and the second conductive sheet 123 in the structure shown in fig. 11.

The first conductive sheet 122 and the second conductive sheet 123 in this embodiment are the same in material and structure. The structure of the first conductive sheet 122 will be described by taking the first conductive sheet 122 as an example. The first conductive sheet 122 is a thin sheet having a thickness of 0.2mm to 0.5mm (including 0.2mm and 0.5 mm). The first conductive sheet 122 includes a guide portion 1221, a fitting portion 1222, a rotating portion 1223, and a welding portion 1224, which are connected in this order. The welding part 1224 is welded to the body 121 and electrically connected to the body 121. The conductive portion facilitates the mounting of the actuating post 13 between the first conductive plate 122 and the second conductive plate 123. When the monitoring device 10 is attached to the skin of the user, the attaching portion 1222 is the portion of the first conductive sheet 122 contacting the second conductive sheet 123.

In this embodiment, the angle between the guiding portion 1221 and the attaching portion 1222 is 30 degrees to 60 degrees (including 30 degrees and 60 degrees), so that the actuating column 13 is installed between the first conductive plate 122 and the second conductive plate 123. The angle between the rotating part 1223 and the welding part 1224 is 15 degrees to 65 degrees (including 15 degrees and 65 degrees) to provide sufficient deformation and reset force for the first conductive plate 122.

Referring to fig. 11 and 12 again, the circuit board 12 further includes a temperature sensor 127, and the temperature sensor 127 is connected to the body 121 and electrically connected to the body 121. When the second end 132 of the actuation post 13 protrudes relative to the adhesive layer 15, the actuation post 13 is spaced from the temperature sensor 127. When the end surface of the second end 132 of the actuating post 13 is flush with the adhesive layer 15, the actuating post 13 contacts the temperature sensor 127, and the temperature of the skin of the user is transmitted to the temperature sensor 127 through the actuating post 13 and is acquired by the temperature sensor 127 because the actuating post 13 contacts the skin of the user.

It will be appreciated that the actuating stem 13 of the present application may also be used to conduct temperature. That is to say, the starting column 13 can realize both temperature acquisition and opening of the monitoring device 10, and one device is dual-purpose, avoids setting up two parts and realizes that temperature acquisition and monitoring device 10 open the too much inner space that occupies the casing 11 that causes respectively, is favorable to the miniaturization of monitoring device 10, still is favorable to the integrated level and the retrenchment degree of whole monitoring device 10, reduces product cost. Simultaneously, because the 13 direct contact user skin of start post in this application, compare in current monitoring devices 10 with the temperature transmission piece setting inside casing 11, the speed that the human body temperature was monitored to start post 13 in this application is better, more accurate.

In some embodiments, as shown in fig. 12, the monitoring device 10 includes a heat transfer medium 128, and the heat transfer medium 128 covers the surface of the temperature sensor 127 to transfer the temperature from the start column 13 to the temperature sensor 127 through the heat transfer medium 128, thereby improving the effective transfer of the temperature between the start column 13 and the temperature sensor 127. The thermally conductive medium 128 may be a thermally conductive silicone grease, a thermally conductive gel, a thermally conductive pad, or the like. In other embodiments, the surface of the temperature sensor 127 may not be provided with a heat conducting medium, and the actuating column 13 is directly in contact with the temperature sensor 127.

In some embodiments, when the second end 132 of the actuating post 13 protrudes relative to the adhesive layer 15, the distance between the heat conducting medium 128 and the portion of the actuating post 13 facing the actuating post is less than the distance between the second end 132 protruding relative to the adhesive layer 15, so that when the end surface of the second end 132 of the actuating post 13 is flush with the adhesive layer 15, the actuating post 13 has a certain amount of compression (10% -30%) on the heat conducting medium 128, so as to ensure that the actuating post 13 is in full contact with the heat conducting medium 128, reduce temperature loss and improve the efficiency of temperature transmission.

Referring to fig. 4 and 14, fig. 14 is a schematic structural view of the actuating post 13 and the related structure of the structure shown in fig. 5.

In this embodiment, the actuating column 13 is made of a metal material. The metal material may be, for example, an aluminum alloy, a copper alloy, stainless steel, or other good thermal conductive material, and when the monitoring device 10 is adhered to the skin of the user, the second end 132 of the actuating post 13 contacts the skin of the user for transmitting the skin temperature of the user to the temperature sensor 127. Of course, in other embodiments, the actuating post 13 may also be made of an insulating material. The monitoring device 10 may transmit the body temperature to the temperature sensor 127 via other temperature transmitting members.

The diameter of the first end 131 of the actuation post 13 is larger than that of the second end 132, and correspondingly, the diameter of the portion of the through hole 1121 of the first housing 11A away from the adhesive layer 15 is larger than that of the portion close to the adhesive layer 15, so as to prevent the first end 131 of the actuation post 13 from being exposed relative to the adhesive layer 15 through the through hole 1121 of the first housing 11A, so as to limit the actuation post 13 to the first housing 11A.

The walls of the starting post 13 and the through hole 1121, and the space between the starting post 13 and the wall accommodating the enclosure 1122 are sealed by the sealing ring 16, so as to prevent external moisture from entering the interior of the housing 11 from the through hole 1121 of the first housing 11A, and ensure that components such as the circuit board 12 and the like in the interior of the housing 11 are not damaged by water entering. Illustratively, the first end 131 of the actuating post 13 is provided with a groove 133 near the outer periphery of the second end 132, and the sealing ring 16 is disposed within the groove 133. The material of the seal ring 16 may be fluororubber, silicone rubber, nitrile rubber, or the like.

The monitoring device 10 further comprises a resilient member 17 as shown in fig. 4 and 14, and the actuating post 13 is resiliently connected to the top wall 111 by the resilient member 17. Specifically, the elastic member 17 penetrates the avoiding hole 126 of the circuit board 12, and has one end connected to the first end 131 and the other end connected to the top wall 111. In this embodiment, a fixing groove 1311 is disposed on an end surface of the first end 131 opposite to the second end 132, one end of the elastic element 17 is fixed in the fixing groove 1311, and the other end abuts against the top wall 111. The elastic member 17 may be a spring or a spring plate. The elastic member 17 may be made of 65Mn steel, SWP-B (SWP-B), iron, austenite-martensite precipitation hardening stainless steel (07 Cr17Ni7 Al), or the like.

Of course, in other embodiments, the elastic member 17 may be fixed to the end surface of the first end 131 opposite to the second end 132 by bonding or the like.

Referring to fig. 15, fig. 15 is a schematic structural diagram of another embodiment of the structure shown in fig. 4.

In other embodiments, as shown in fig. 15, the top wall 111 is further provided with a sinking groove 1114, and one end of the elastic element 17 abutting against the top wall 111 is limited in the sinking groove 1114, so that the elastic element 17 is stably fixed to the top wall 111 without deflection and resulting in functional failure.

Referring to fig. 16, fig. 16 is a schematic structural diagram of another embodiment of the structure shown in fig. 4.

In other embodiments, as shown in fig. 16, the top wall 111 is further provided with a limiting structure 1115, the limiting structure 1115 and the top wall 111 together form a limiting space, and one end of the elastic element 17 abutting against the top wall 111 is limited in the limiting space, so that the elastic element 17 is stably fixed to the top wall 111, and cannot deflect to cause functional failure.

Referring to fig. 11, 12 and 14, the first end 131 of the actuating post 13 is provided with a first arm 134, the first arm 134 is insulated, and the first arm 134 is used for cooperating with the first conductive plate 122 and the second conductive plate 123 to implement the actuation of the monitoring device 10. Specifically, when the second end 132 of the actuating post 13 protrudes from the adhesive layer 15, the first arm 134 is located between the first conductive plate 122 and the second conductive plate 123 to space the first conductive plate 122 from the second conductive plate 123, specifically, between the bonded portions of the two conductive plates. That is, the first conductive pad 122 and the second conductive pad 123 are spaced apart from each other by the first arm 134 when the monitoring device 10 is not applied to the skin of the user.

When the end surface of the second end 132 of the actuating post 13 is flush with the adhesive layer 15, i.e. when the monitoring device 10 is applied to the skin of the user, the first arm 134 moves in a direction away from the bottom wall 112, and is away from the attached portion of the first conductive plate 122 and the second conductive plate 123, and the first conductive plate 122 and the second conductive plate 123 are in contact conduction under the action of elastic force, so that the switch circuit is closed and the monitoring device 10 is opened.

In this embodiment, the first arm 134 and the first end 131 are integrally formed, and the first arm 134 and the first end 131 can be formed by an injection molding process. That is, the first arm 134 and the first end 131 are made of the same material and are both conductive. The surfaces of the first arm 134, which are in contact with the first conductive plate 122 and the second conductive plate 123, may be coated with a non-conductive coating or adhered with an insulating film, such as a resin coating, an insulating film made of polycarbonate, epoxy resin, or the like, to achieve insulation, so as to prevent the first conductive plate 122 and the second conductive plate 123 from being connected through the first arm 134.

Of course, in a realization scenario of other embodiments, the material of the first arm 134 may be a metal material, and may be fixed to the first end 131 of the actuating column 13 by welding and bonding. The surface of the first arm 134 is coated with an insulating material. In another implementation scenario of other embodiments, the first arm 134 may also be made of plastic, and may be fixed to the first end 131 of the actuating column 13 by bonding, screwing, or the like.

Referring to fig. 14 and 17, fig. 17 is a schematic cross-sectional view of the structure shown in fig. 3 in another state.

Actuation post 13 further includes a second arm 135, second arm 135 being coupled to first end 131. The second arm 135 is spaced apart from the first arm 134. The enclosure 1122 is received with notch B to clear the second arm 135. The second arm 135 is used to transfer the temperature of the user's skin to the temperature sensor 127. It will be appreciated that when the monitoring device 10 is worn on the skin of a user, the second end 132 of the actuating post 13 contacts the skin of the user and the temperature of the skin of the user is transmitted through the second end 132 to the first end 131, then to the second arm 135, and finally to the temperature sensor 127 via the second arm 135.

Specifically, when the end surface of the second end 132 of the actuating post 13 is flush with the adhesive layer 15, the second arm 135 contacts the temperature sensor 127 through the heat transfer medium 128. In this embodiment, the distance between the heat conducting medium 128 and the second arm 135 is smaller than the distance between the second end 132 and the adhesive layer 15.

Referring to fig. 4, 14 and 18, fig. 18 is a schematic structural view of the structure shown in fig. 4 in another state.

The first end 131 of the actuating post 13 is provided with a catch 136. The hook 136 is disposed on an end surface of the first end 131 facing away from the second end 132. In the process that the starting column 13 moves away from the bottom wall 112, the hook 136 penetrates through the avoiding hole 126 of the circuit board 12 and abuts against the surface of the circuit board 12 facing the top wall 111, so that the problem that the first arm 134 is contacted with the first conducting strip 122 and the second conducting strip 123 again and the switching circuit is disconnected due to the fact that the starting column 13 moves towards the direction close to the skin in the moving process of a user can be prevented.

In this embodiment, the number of the hook claws 136 is two, and the two hook claws 136 are arranged oppositely, so as to ensure that the starting column 13 is balanced and stably abutted against the circuit board 12. Of course, in other embodiments, the number of the hooks 136 may be one or more than three. The number of pawls 136 is not limited by the present application.

Fig. 19 is a partially enlarged schematic view of the structure shown in fig. 4, as shown in fig. 4 and 19.

Hook 136 includes a beveled surface 1361 and the wall of relief hole 126 includes a beveled surface 1261 that mates with beveled surface 1361 of hook 136 to facilitate passage of hook 136 through relief hole 126. The inclined surface 1361 of the hook 136 and the inclined surface 1261 of the avoiding hole 126 are used for guiding so that the hook 136 slides into the avoiding hole 126 and penetrates the avoiding hole 126 when the actuating rod 13 moves back to the bottom wall 112. Of course, in other embodiments, the hook 136 includes a chamfer 1361 but the wall of the relief hole 126 does not include a chamfer, or the wall of the relief hole 126 includes a chamfer 1260 but the hook 136 does not include a chamfer. Of course, the specific structure of the inclined surface 1361 of the hook 136 and the inclined surface 1261 of the avoidance hole 126 is not limited to that shown in fig. 19, as long as the hook 136 can smoothly penetrate the avoidance hole 126.

Of course, in other embodiments, the actuating column 13 may not be provided with a hook, and the body 121 of the circuit board 12 may be provided with a fastening structure, it is understood that the first arm 134 gradually approaches the body 121 of the circuit board 12 during the movement of the first arm 134 away from the bottom wall 112, and when the end surface of the second end 132 of the actuating column 13 is flush with the adhesive layer 15, the first arm 134 just moves to the fastening structure and is fastened and fixed by the fastening structure, so as to prevent the user from moving the actuating column 13 towards the direction close to the skin during the movement, which causes the first arm 134 to contact with the first conductive plate 122 and the second conductive plate 123 again, and causes the switch circuit to be disconnected.

Referring to fig. 6 and 20, fig. 20 is a partial structural view of the analytical sensor 14 and the circuit board 12 of the structure shown in fig. 5.

The analysis sensor 14 includes a connecting portion 141 and a sensing portion 142 connected, the connecting portion 141 being electrically connected to the body 121 of the circuit board 12, the sensing portion 142 being for penetrating the bottom wall 112 from inside the housing 11 and protruding the adhesive layer 15. When the monitoring device 10 is applied to the skin of a user, the sensing portion 142 penetrates deeply under the skin of the user to monitor the blood glucose concentration of the user.

Referring to fig. 21 and 22, fig. 21 is a partial schematic structural view of another embodiment of the monitoring device 10 shown in fig. 3. Fig. 22 is a schematic view of the structure of fig. 21 in another state.

This embodiment is substantially the same as the embodiment shown in fig. 3, except that the first conductive plate 122 and the second conductive plate 123 in this embodiment have different structures and the first conductive plate 122 and the second conductive plate 123 are matched with the actuating posts 13.

Specifically, the second conductive sheet 123 is fixed to the body 121 of the circuit board 12 and is electrically connected to the body 121 of the circuit board 12. The second conductive sheet 123 may be flat and integrally fixed to the body 121, or may be non-flat and partially fixed to the body 121. The first conductive sheet 122 has elasticity, and a portion of the first conductive sheet 122 is fixed to the body 121 of the circuit board 12 and electrically connected to the body 121, and another portion is spaced apart from the second conductive sheet 123 on a side opposite to the body 121.

When the second end 132 of the actuating post 13 protrudes relative to the adhesive layer 15, the first arm 134, the first conductive plate 122 and the second conductive plate 123 are sequentially arranged at intervals, and the switch circuit of the circuit board 12 is turned off. When the end surface of the second end 132 is flush with the adhesive layer 15, the first arm 134 moves toward the first conductive sheet 122, and presses and contacts the first conductive sheet 122 to the second conductive sheet 123, the first conductive sheet 122 and the second conductive sheet 123 are in contact and conducted, the switch circuit of the circuit board 12 is closed, and the monitoring device 10 is started.

In this embodiment, the first conductive plate 122 is kept in contact with the second conductive plate 123 by the external force applied by the first arm 134, and compared with the embodiment shown in fig. 12 in which the first conductive plate 122 and the second conductive plate 123 are kept in contact by the deformation force generated by deformation, the first conductive plate 122 and the second conductive plate 123 in this embodiment can still be kept in contact during the violent movement, and the two conductive plates are less prone to separation, which more effectively ensures the normal operation of the monitoring device 10.

As shown in fig. 21 and 23, the first conductive sheet 122 includes a soldering portion 1224, a fitting portion 1222, and a position-limiting portion 1225, which are connected in sequence. The soldering part 1224 is soldered to the body 121 of the circuit board 12 and electrically connected with the body 121. The engaging portion 1222 is used for contacting and engaging with the second conductive plate 123 when the first arm 134 presses the first conductive plate 122. The stopper 1225 is used to prevent the first conductive sheet 122 from being detached from the first arm 134.

Referring to fig. 24, fig. 24 is a schematic structural diagram of another embodiment of the structure shown in fig. 22.

This embodiment is substantially the same as the embodiment shown in fig. 21, except that the activation button 18 cooperates with the activation post 13 to effect activation of the monitoring device 10.

Specifically, the circuit board 12 includes an activation button 18, and the activation button 18 is fixed and electrically connected to a body 121 of the circuit board 12. When the monitoring device 10 is not applied to the skin of the user, the first arm 134 of the actuation post 13 is spaced from the actuation button 18 and the switching circuit of the circuit board 12 is open. When the monitoring device 10 is attached to the skin of the user, the end surface of the second end 132 of the actuation post 13 is flush with the adhesive layer 15, the first arm 134 moves toward the actuation button 18 and presses on the actuation button 18, the switch circuit of the circuit board 12 is closed, and the monitoring device 10 is actuated.

In the embodiment, the monitoring device 10 is started by matching the starting post 13 with the starting button 18, and compared with a mode of matching the starting post 13 with the first conductive sheet and the second conductive sheet, the monitoring device does not need to rely on the elasticity of the conductive sheets to realize electric conduction, and is more reliable than the conductive sheets.

Of course, in other embodiments, the actuating post 13 may also effect the opening of the monitoring device 10 by cooperating with structures other than a conductive tab, the actuating button 18. The present application is not limited thereto.

The above are only some examples and embodiments of the present application, and the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
