[0045] At present, the blood glucose patch products basically use button batteries to directly power the internal circuit of the blood glucose patch, that is, when the blood glucose patch is produced, its internal circuit will begin to consume the battery power, but the production, sales and storage cycle of blood glucose patch products is relatively long. This leads to the fact that in order to ensure that the functional availability time of the product can reach the specified time when the user actually uses the product, the actual battery capacity used will be relatively large, which in turn leads to a relatively large battery volume.

[0046] To this end, the main purpose of this application is to propose a blood sugar patch, referring to Figure 1-7 In one embodiment of the present application, the blood glucose patch includes a blood glucose function module, and the blood glucose patch includes:

[0047] A patch body 10, wherein the blood sugar function module is disposed in the patch body 10;

[0048] A shielding component 20, which is disposed on the end surface of the patch body 10, and has a shielding state and an open state;

[0049] A switch component 30, wherein the input end of the switch component 30 is connected to the battery power supply end, and the output end of the switch component 30 is connected to the power supply end of the blood glucose function module;

[0050] A trigger component 40, wherein the trigger component 40 is electrically connected to the switch component 30, and the shielding component 20 is linked to the trigger component 40 to control the working state of the switch component 30;

[0051] Wherein, when the shielding component 20 is in the shielding state, the switch component 30 disconnects the passage between the battery power supply terminal and the power supply terminal of the blood glucose function module;

[0052] When the shielding component 20 is in an open state, the trigger component 40 controls the switch component 30 to conduct the path between the battery power terminal and the power terminal of the blood glucose function module.

[0053] In this embodiment, the blood glucose function module includes a blood glucose sensor for detecting the blood glucose concentration in the user's body, and a microcontroller for determining whether the user's blood glucose level is within a normal range based on a preset algorithm and threshold, and outputting corresponding prompts or alarm information.

[0054] Optionally, in one embodiment, the switch component 30 can be implemented by at least one switch tube, such as a MOS tube, an IGBT tube, a thyristor, a triode, a power tube, etc., and / or by at least one switch device, such as a contactor, a circuit breaker and a relay.

[0055] Optionally, in one embodiment, the trigger component 40 can be implemented by using an occlusion detection sensor module, such as an infrared tube detection sensor, a light intensity detection sensor, etc., or by a combination of a sensor and a control device. The occlusion detection sensor module can detect the current state of the occlusion component 20. If it is in an occlusion state, that is, the occlusion detection sensor module detects that the occlusion component 20 is not set on the end face of the patch body 10 (equivalent to the end face not being blocked by the occlusion component 20), the occlusion detection sensor module will confirm that the current occlusion component 20 is in an open state, and then control the switch component 30 to conduct the passage between the battery power supply end and the power supply end of the blood glucose function module.

[0056] Optionally, in one embodiment, the trigger component 40 can be implemented by a mechanical switch, such as a key, a button, a micro switch, a lever switch, etc. The shielding component 20 can be controlled by linkage with the mechanical switch through a linkage structure disposed inside the patch body, so that when the shielding component 20 is uncovered by the user and is in an open state, the linkage structure triggers the mechanical switch, so that the mechanical switch outputs a corresponding signal to the switch component, and the switch component is in a conducting state. Compared with the above-mentioned embodiment using the shielding detection sensor module, the present embodiment uses a mechanical switch as the trigger component 40 without consuming any electrical energy, thereby further reducing the power consumption of the blood glucose patch.

[0057] In this embodiment, the shielding component 20 can be a paper shielding component, a cover shielding component, etc. When the user needs to use the blood glucose patch, the shielding component 20 can be switched to an open state (for example, uncovering the paper shielding component or opening the cover shielding component), so that the trigger component 40 controls the switch component 30 to conduct the path between the battery power supply terminal and the blood glucose functional module, and the blood glucose functional module starts to consume power to work. In this way, the shielding component 20 of the blood glucose patch of the present application is in a shielding state during the production, sales, and storage waiting cycles. In this case, the blood glucose functional module cannot consume the power of the battery, thereby avoiding unnecessary power consumption of the blood glucose patch during the production, sales, and storage waiting cycles, and only works when the user starts to use it, thereby reducing the power consumption of the blood glucose patch.

[0058] Furthermore, since the power consumption of the blood glucose patch is reduced, compared with the existing blood glucose patches, the blood glucose patch of the present application can achieve the specified working time while using a smaller battery. The smaller battery means that the overall volume and weight of the blood glucose patch of the present application can be further reduced compared with the existing blood glucose patches, thereby reducing the user's wearing burden and making it easier to carry and hide, thereby meeting the user's daily needs.

[0059] In addition, in another embodiment, the end surface of the patch body 10 includes an upper end surface and a lower end surface, and the shielding component 20 can be arranged on the upper end surface or the lower end surface. When designing, "this shielding object needs to be uncovered when in use" can be marked on the outward side of the shielding component 20 or at a position of the patch body 10 close to the shielding component 20, so as to remind the user to uncover the shielding component 20 when in use.

[0060] Optionally, refer to Figure 3 In one embodiment of the present application, the shielding assembly 20 includes: a shielding portion 21 and a handle portion 22 connected to the shielding portion 21; the position where the shielding portion 21 and the handle portion 22 are connected is a triggering area, and the triggering assembly 40 is arranged corresponding to the triggering area;

[0061] The handle portion 22 is used to apply pressure to the trigger area when triggered, so as to trigger the trigger component 40 to control the switch component 30 to open the path between the battery power terminal and the power terminal of the blood glucose function module.

[0062] In this embodiment, optionally, the shielding portion 21 includes release paper, and the handle portion 22 includes a release paper hard handle. The shielding state of the release paper is the state in which the release paper is attached to the end surface, and the open state of the release paper is the state in which the release paper is uncovered.

[0063] Optionally, the trigger component 40 can be a capacitive sensor or a pressure sensor, which is used to output a control signal switch component 30 after receiving a preset pressure, so that the switch component 30 is turned on, and is set at the position corresponding to the trigger area. For example, based on the above embodiment, the handle 22 is not only a part connected to the shielding part 21, but also a lever point for the user to apply force, so as to facilitate the user to open the shielding part 21. When the user opens the shielding part 21, the user needs to first place the thumb on the trigger area (the triggering area is located at the connection between the handle 22 and the shielding part 21, which is the area that the user naturally contacts when applying force), and clamp the appropriate position of the handle 22 with the index finger, and then the user lifts the handle 22 with force, and at the same time, the thumb applies pressure to the trigger area. The action of lifting the handle 22 will drive the shielding part 21 to separate from the blood glucose patch body 10 (open state). In the process of the user lifting the handle 22, the pressure on the trigger component 40 will control the switch component 30 to conduct the passage between the battery power supply end and the power supply end of the blood glucose function module. In this way, the design of the uncovering portion 21 of the blood glucose patch of the present application fully considers the user's hand structure and operating habits, making the operation process natural, smooth and comfortable, and the design of uncovering the shielding portion 21 is combined with the trigger component 40, so that when the user uses the blood glucose patch, the battery inside the blood glucose patch just powers on its internal circuit. Compared with the existing blood glucose patches, the internal circuit of the blood glucose patch of the present application consumes no power at all during the factory and production, sales and storage cycle, and the internal circuit only starts working when the user starts to use it, thereby reducing the power consumption of the blood glucose patch of the present application.

[0064] Based on the above embodiment, the trigger component 40 may also be a micro switch trigger component 41. When the user lifts the handle 22 with force, the thumb applies pressure to the trigger area. After the micro switch trigger component 41 is subjected to sufficient pressure, its moving contact contacts the fixed contact to control the switch component 30 to conduct the passage between the battery power supply terminal and the power supply terminal of the blood glucose function module. The control process may be that after the micro switch trigger component 40 is triggered, the control signal is transmitted to the switch component 30 via the micro switch trigger component 41 to conduct the switch component 30, or the triggering of the micro switch trigger component 41 may directly control the conduction of the switch component 30 through a physical connection. For example, the movement of the moving contact may directly push or pull the mechanical components inside the switch component 30, so that the mechanical components move to the disconnected position in the passage between the battery power supply terminal and the blood glucose function module, thereby conducting the passage between the battery power supply terminal and the blood glucose function module.

[0065] Optionally, the shielding portion 21 may be a protective cover, which is connected to the end face by a plurality of buckles, and the handle portion 22 may be a button for controlling the tightness of the buckles. When the button is pressed and triggered, the plurality of buckles are released to allow the protective cover to fall off, and when the button is pressed and triggered, the trigger assembly 40 disposed in the trigger area is also subjected to pressure so that the trigger assembly 40 controls the switch assembly 30 to open the passage between the battery power terminal and the blood glucose function module.

[0066] For further reference, Figure 4 , the micro switch trigger component 41 includes:

[0067] A first resistor R1, a first capacitor C1 and a micro switch, wherein the first end of the first resistor R1 is connected to the battery power end, the second end of the first resistor R1 is electrically connected to the first end of the micro switch and the first end of the first capacitor C1 respectively, the second end of the first capacitor C1 is grounded, and the second end of the micro switch is electrically connected to the controlled end of the switch component 30.

[0068] In this embodiment, when the user does not uncover the shielding portion 21, the micro switch is in an off state, in which the battery power supply terminal charges the first capacitor C1 to increase the voltage of the first capacitor C1. When the user uncovers the shielding portion 21, the micro switch is triggered to conduct the path between the controlled end of the switch component 30 and the first capacitor C1, and the voltage of the controlled end of the switch component 30 increases, so that the switch component 30 conducts the path between the battery power supply terminal and the power supply terminal of the blood glucose function module.

[0069] refer to Figure 5 In one embodiment of the present application, the switch assembly 30 includes:

[0070] A main switch circuit 31, wherein the input end of the main switch circuit 31 is electrically connected to the power supply end of the battery, and the output end of the main switch circuit 31 is electrically connected to the power supply end of the blood glucose function module;

[0071] A driving circuit 32, wherein a control end of the driving circuit 32 is electrically connected to a controlled end of the main switch circuit 31;

[0072] When the shielding component 20 is in an open state, the trigger component 40 controls the driving circuit 32 to drive the main switch circuit 31 to operate, so as to open the path between the battery power supply terminal and the power supply terminal of the blood glucose function module.

[0073] In this embodiment, the main switch circuit 31 can be implemented by at least one switch tube, such as a MOS tube, an IGBT tube, a thyristor, a triode, a power tube, etc., and / or by at least one switch device, such as a contactor, a circuit breaker and a relay.

[0074] In this embodiment, the drive circuit 32 can adopt a direct drive circuit, which is composed of single electronic components (such as diodes, transistors, resistors, capacitors, etc.) connected together; the drive circuit 32 can also adopt an isolated drive circuit, which includes optocouplers, transformers, capacitors and other devices with electrical isolation functions, which can achieve effective signal transmission while ensuring circuit safety.

[0075] In this embodiment, reference Figure 6 The main switch circuit 31 includes: a first switch tube Q1, the input end of the first switch tube Q1 is electrically connected to the battery power end, and the output end of the first switch tube Q1 is electrically connected to the power end of the blood glucose function module;

[0076] The driving circuit 32 includes: a second switch tube Q2, a second resistor R2 and a third resistor R3, wherein a first end of the second resistor R2 is electrically connected to a power input end, a second end of the second resistor R2 is electrically connected to an input end of the second switch tube Q2, a first end of the third resistor R3 is electrically connected to the trigger component 40, and a second end of the third resistor R3 is electrically connected to a controlled end of the second switch tube Q2;

[0077] a third switch tube Q3 and a fourth resistor R4, wherein a first end of the fourth resistor R4 is electrically connected to a battery power supply end, a second end of the fourth resistor R4 is electrically connected to an input end of the third switch tube Q3, and a controlled end of the third switch tube Q3 is electrically connected to an input end of the second switch tube Q2;

[0078] a fourth switch tube Q4, a fifth resistor R5 and a sixth resistor R6, wherein the output end of the third switch tube Q3 is electrically connected to the first end of the fifth resistor R5 and the first end of the sixth resistor R6 respectively, the second end of the sixth resistor R6 is grounded, the second end of the fifth resistor R5 is electrically connected to the controlled end of the fourth switch tube Q4, and the output end of the fourth switch tube Q4 is grounded;

[0079] a seventh resistor R7, an eighth resistor R8 and a ninth resistor R9, wherein a first end of the seventh resistor R7 is electrically connected to a battery power supply end, a second end of the seventh resistor R7 is electrically connected to a second end of the eighth resistor R8 and a first end of the ninth resistor R9 respectively, a first end of the eighth resistor R8 is electrically connected to a controlled end of the first switch tube Q1, and a second end of the ninth resistor R9 is electrically connected to an input end of the fourth switch tube Q4.

[0080] The second switch tube Q2 and the fourth switch tube Q4 are both NMOS tubes, and the first switch tube Q1 and the third switch tube Q3 are both PMOS tubes.

[0081] In this embodiment, when the shielding part 21 is in the shielding state, the trigger component 40 does not output a control signal to the second switch tube Q2. At this time, the second switch tube Q2 is in the disconnected state. Accordingly, the gate-source voltage difference of the first switch tube Q1, the third switch tube Q3 and the fourth switch tube Q4 is zero. The first switch tube Q1, the third switch tube Q3 and the fourth switch tube Q4 are all in the disconnected state, so that the path between the battery power supply end and the power supply end of the blood glucose function module is disconnected. When the shielding component 20 is in the open state, the trigger component 40 outputs a high-level signal to the second switch tube Q2 to turn on the second switch tube Q2. Accordingly, the gate-source voltage difference of the third switch tube Q3, the fourth switch tube Q4 and the first switch tube Q1 is greater than the turn-on threshold. The third switch tube Q3, the fourth switch tube Q4 and the first switch tube Q1 are turned on in sequence, thereby turning on the path between the battery power supply end and the power supply end of the blood glucose function module.

[0082] In this embodiment, the blood glucose patch also includes a second capacitor C2 and a third capacitor C3. The first end of the second capacitor C2 and the first end of the third capacitor C3 are both electrically connected to the output end of the first switch tube Q1, and the second end of the second capacitor C2 and the second end of the third capacitor C3 are both grounded. The second capacitor C2 and the third capacitor C3 both play a filtering role to make the voltage output from the battery to the blood glucose function module smoother.

[0083] In one embodiment of the present application, the blood glucose patch also includes: a switch state maintaining circuit 50, which is connected to the controlled end of the switch component 30; the switch state maintaining circuit 50 is used to keep the switch component 30 conducting the path between the battery power end and the power end of the blood glucose functional module when the shielding component 20 is in an open state.

[0084] In this embodiment, the switch state holding circuit 50 is mainly used to ensure that after the shielding component 20 is opened, the switch component 30 can continue to maintain the on state even if the trigger component 40 (such as a micro switch) is no longer subjected to external force. This helps to avoid the problem of power interruption caused by misoperation or instability of the trigger component 40 during the blood sugar measurement process.

[0085] In this embodiment, optionally, the switch state holding circuit 50 may adopt a latch or a trigger. When the trigger component 40 is activated, the latch or the trigger captures the control signal output by the trigger component 40, and maintains the output control signal to the switch component 30 when the shielding component 20 remains in the open state, so that the switch component 30 is always maintained in the on state.

[0086] Optionally, the switch state holding circuit 50 includes a tenth resistor R10, a first end of the tenth resistor R10 is connected to the controlled end of the switch component 30, and a second end of the tenth resistor R10 is electrically connected to the power supply end of the blood glucose function module.

[0087] Combined with the above circuit for explanation, refer to Figure 7 , the second end of the tenth resistor R10 is connected to the first end of the third resistor R3. When the battery power supply end is connected to the power supply end of the blood glucose function module, the power supply end of the blood glucose function module sequentially outputs a high level to the second switch tube Q2 through the tenth resistor R10 and the third resistor R3, so that the second switch tube Q2 is always in a conductive state. Correspondingly, the path between the battery power supply end and the blood glucose function module is also always in a conductive state. In this way, when the user accidentally touches the micro switch to disconnect the micro switch, due to the drainage effect of the tenth resistor R10, the second switch tube Q2 still remains in a conductive state, which helps to avoid the problem of power interruption caused by the user's misoperation or instability of the trigger component 40 during the blood glucose measurement process.

[0088] In one embodiment of the present application, the patch body 10 has a fixed end surface for fixing itself on the user's skin; the shielding component 20 is arranged on the fixed end surface;

[0089] When the shielding assembly 20 is in a shielding state, the fixed end surface is shielded; when the shielding assembly 20 is in an open state, the fixed end surface is exposed.

[0090] In this embodiment, when the shielding component 20 is in the shielding state, the shielding component 20 will completely or partially cover the fixed end surface, thereby protecting the fixed end surface from the influence of the external environment, such as preventing the intrusion of dust, moisture or dirt, and avoiding contamination of the fixed end surface. When the user uses the blood glucose patch, the user must first uncover the shielding component 20 before the fixed end face of the blood glucose patch can act on the skin tissue. When the user uncovers the shielding component 20, the path between the battery power end and the power end of the blood glucose functional module is just connected. In this way, if the shielding component 20 is set on other end faces of the patch body 10, it is necessary to indicate in the instruction manual or around the shielding component 20 that the blood glucose patch can only work after the shielding component 20 is uncovered. Compared with setting the shielding component 20 on the fixed end face, since the user must first uncover the shielding component 20 when using the blood glucose patch before the fixed end face of the blood glucose patch can act on the skin tissue, if the shielding component 20 is set on the fixed end face, there is no need to explain to the user the technical instructions that the blood glucose patch can only work after the shielding component 20 is uncovered, which reduces the user's cognitive burden and improves the convenience of use.

All equivalent structural changes made by using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
