Description

Technical Field

[0001] The present invention mainly relates to the field of medical devices, and in particular to an analyte detection system. Background Art

[0002] The pancreas in a normal person's body can automatically monitor the glucose content in the human blood and automatically secrete the required insulin / glucagon. However, the pancreas of diabetic patients has abnormal function and cannot normally secrete the insulin required by the human body. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function in the human body, and diabetes is a lifelong disease. At present, medical technology cannot cure diabetes, and can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar.

[0003] Diabetic patients need to test their blood sugar before injecting insulin into their bodies. Currently, most testing methods can continuously test blood sugar and send blood sugar data to remote devices in real time for users to view. This testing method is called continuous glucose monitoring (CGM). This method requires the detection device to be attached to the surface of the skin and the probe it carries to be inserted into the subcutaneous tissue fluid to complete the test.

[0004] Currently, when using the analyte detection system, the user needs to find different input locations in the remote device to manually input the function instructions into the remote device, thereby controlling the analyte detection system to perform the corresponding function. This input process is cumbersome and the user experience is poor.

[0005] Therefore, the prior art urgently needs an analyte detection system that simplifies the function instruction input process and provides a good user experience. Summary of the invention

[0006] An embodiment of the present invention discloses an analyte detection system. After the user's body movements are sensed or recognized as functional instructions by a motion sensor, the internal circuit can directly control the sensor or transmitter to execute the functional instructions without the user manually inputting the functional instructions, thereby improving the user experience.

[0014] According to one aspect of the present invention, the body movements include walking, jumping, running, squatting, leg movements, arm movements, bending over, body twisting, and / or tapping, shaking, and pressing the motion sensor.

[0015] According to one aspect of the present invention, according to different numbers and / or combinations of body movements, the internal circuit controls the sensor unit or the transmitter to execute corresponding functional instructions.

[0016] According to one aspect of the present invention, the limb movements sensed or recognized by the motion sensor within a fixed time t are valid limb movements, and the limb movements sensed or recognized beyond the fixed time t are invalid limb movements. Based on the valid limb movements, the internal circuit controls the sensor unit or transmitter to execute corresponding functional instructions.

[0017] According to one aspect of the present invention, the fixed time t is 0.5s~5s.

[0018] According to one aspect of the present invention, the fixed time t=1 s.

[0019] According to one aspect of the present invention, the motion sensor is one or more of an acceleration sensor, a tilt sensor, a vibration sensor, and a rotation sensor.

[0020] According to one aspect of the present invention, the acceleration sensor is a three-axis acceleration sensor.

[0021] According to one aspect of the present invention, it also includes a body movement confirmation module, which is connected to the motion sensor and is used to instruct the motion sensor to start / stop sensing or identifying the user's body movement.

[0022] According to one aspect of the present invention, a continuous glucose monitoring device is also disclosed, including an analyte detection system and a receiver, wherein the receiver is used to receive analyte parameter information sent by a transmitter and indicate the analyte parameter information to a user.

[0023] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0024] In the analyte detection system disclosed in the present invention, the motion sensor is used to sense or identify the user's body movements, and different body movements represent different functional instructions. According to the body movements sensed or identified by the motion sensor, the internal circuit controls the sensor or transmitter to execute the corresponding functional instructions. Compared with manual input, body movements directly used as functional instructions avoid users from searching for the input location of functional instructions on remote devices and manual operation input, which is simple and convenient, and the user experience is better.

[0025] Furthermore, the battery is sealed inside the transmitter, which can provide good waterproof effect, facilitate users to carry out underwater sports, and provide users with a better experience.

[0026] Furthermore, the battery is sealed in the bottom shell. Since the bottom shell is disposable, the user can replace the battery with a new one when replacing the bottom shell. The high-performance battery can be maintained during the analyte detection system, thereby providing reliable detection data.

[0027] Furthermore, the body movements include walking, jumping, running, squatting, leg movements, arm movements, bending, body twisting, and / or tapping, shaking, and pressing the motion sensor. There are many types of body movements, and they are relatively easy for users to perform.

[0028] Furthermore, the combination of different numbers and types of body movements also improves the flexibility and safety of the analyte detection system when executing functional instructions.

[0029] Furthermore, the limb movements sensed or recognized by the motion sensor within a fixed time t are effective limb movements. The internal circuit controls the sensor unit or transmitter to execute corresponding functional instructions based on the effective limb movements, avoiding erroneous instructions caused by the user's unnecessary limb movements and improving the safety of the system when used.

[0030] Furthermore, the analyte detection system further includes a body movement confirmation module, which is connected to the motion sensor. The action confirmation module is configured to confirm whether the user's body movement meets the standard or meets the requirements, thereby improving the safety of the analyte detection system.

[0031] Furthermore, the motion sensor is one or more of an acceleration sensor, a tilt sensor, a vibration sensor, and a rotation sensor. Multiple motion sensors can be selected and used in combination to improve the accuracy and sensitivity of identifying limb movements.

[0032] Furthermore, the acceleration sensor is a three-axis acceleration sensor. The three-axis acceleration sensor can detect changes in acceleration in three directions of X, Y, and Z axes, has the advantage of quickly detecting body movements, and improves the sensitivity of movement detection.

[0033] Furthermore, the internal circuit includes a first subcircuit connected to the sensor and a second subcircuit connected to the transmitter, the first subcircuit and the second subcircuit are electrically connected, and the motion sensor is connected to the first subcircuit and the second subcircuit respectively. After the body movement corresponding to the sensor-related instruction is sensed by the motion sensor, a signal is generated, and the signal will only be received by the first subcircuit, but not by the second subcircuit; after the body movement corresponding to the transmitter-related instruction is sensed by the motion sensor, a signal is generated, and the signal will only be received by the second subcircuit, but not by the first subcircuit, thereby improving the accuracy of action detection.

[0034] Furthermore, the motion sensor includes a first sub-motion sensor and a second sub-motion sensor, the first sub-circuit is electrically connected to the first sub-motion sensor, the second sub-circuit is electrically connected to the second sub-motion sensor, and the first sub-circuit is electrically connected to the second sub-motion sensor. The first sub-motion sensor stores body motion data corresponding to the sensor function instruction, and the second sub-motion sensor stores body motion data corresponding to the transmitter function instruction. When the user sends a body motion corresponding to the sensor function instruction, the first sub-motion sensor can recognize and generate a signal, which is transmitted to the first sub-circuit. The first sub-circuit controls the sensor to complete the corresponding function instruction. At this time, the second sub-motion sensor cannot recognize the body motion. Therefore, while improving the accuracy of motion detection, the power consumption of the system is also reduced.

[0035] The present invention also discloses a continuous glucose monitoring device, including an analyte detection system and a receiver. The receiver is used to receive analyte parameter information sent by a transmitter and indicate the analyte parameter information to a user. Since an analyte detection system that can change functional instructions through body movements is used, the continuous glucose monitoring device is also simpler and more convenient, and the user experience is better.

[0045] As mentioned above, the analyte detection system in the prior art requires the user to find the command input location on the remote device and manually input functional instructions, which results in a poor user experience.

[0046] After research, it was found that the cause of the above problems is that there is no sensing structure in the analyte detection system to sense the user's body movements, and body movements cannot be used as functional instructions.

[0047] In order to solve this problem, the present invention provides an analyte detection system, which is provided with a motion sensor for sensing or identifying body movements that directly serve as functional instructions, thereby improving the user experience.

[0048] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments should not be construed as limiting the scope of the present invention unless otherwise specifically stated.

For example, the thickness, width, length or distance of certain units may be enlarged relative to other structures.

[0050] The following description of the exemplary embodiments is merely illustrative and is not intended to limit the present invention and its application or use in any sense. Techniques, methods and devices known to ordinary technicians in the relevant field may not be discussed in detail here, but where applicable, these techniques, methods and devices should be considered as part of this specification.

[0051] It should be noted that like reference numerals and letters denote similar items in the following figures, and thus, once an item is defined or described in one figure, it will not require further discussion in the subsequent figure descriptions.

[0052] Figure 1 This is a structural schematic diagram of an analyte detection system according to an embodiment of the present invention. The analyte detection system 10 includes a transmitter unit 101. The transmitter unit 101 includes a transmitter housing 1011, an internal circuit 1012, a transmitter 1013 and a motion sensor 1014. The internal circuit 1012, the transmitter 1013 and the motion sensor 1014 are arranged inside the transmitter housing 1011.

[0053] In an embodiment of the present invention, the internal circuit 1012 includes a first electrical contact 10121 that is led out to the outside of the transmitter housing 1011. The area where the first electrical contact 10121 contacts the transmitter housing 1011 is paved with waterproof and insulating materials, preferably including but not limited to one or more combinations of flexible materials, elastic materials, and stretchable materials, and further preferably including but not limited to one or more combinations of epoxy resins, silicone resins, and gels.

[0054] In an embodiment of the present invention, the transmitter 1013 is used to transmit information to the outside world. The information transmission method includes but is not limited to one or more combinations of Bluetooth, near field communication (NFC), radio frequency identification (RFID), visible light wireless communication (LIFI), and wireless network communication (WIFI). The information transmission object is a user's handheld device, mobile phone, tablet, etc., so that the user can understand the analyte parameter information in a visual form, which is convenient for the user to use.

[0055] In the embodiment of the present invention, the motion sensor 1014 includes but is not limited to one or more of an acceleration sensor, a tilt sensor, a vibration sensor, and a rotation sensor.

[0056] In one embodiment of the present invention, the motion sensor 1014 is a three-axis acceleration sensor, which can detect changes in acceleration in three directions: X, Y, and Z. It has the advantage of quickly detecting limb movements, more comprehensively identifying limb movements, and improving the sensitivity of motion detection.

[0057] In another embodiment of the present invention, the motion sensor 1014 is a rotation sensor, which can accurately detect the user's body movements such as rotation, such as turning in circles.

[0058] In another embodiment of the present invention, the motion sensor 1014 is a vibration sensor, which can accurately detect the user's body movements such as slapping.

[0059] In another embodiment of the present invention, the motion sensor 1014 is a combination of a three-axis acceleration sensor, a rotation sensor and a vibration sensor. This combined motion sensor can realize more and more accurate body movement detection, enrich the user's choices and improve the user experience.

[0060] Continue to refer to Figure 1The analyte detection system 10 also includes a sealing ring 102 for providing waterproof protection in a humid or underwater environment; the sensor 103 includes a probe 1031 and a conductive adhesive strip 1032, the probe 1031 and the conductive adhesive strip 1032 are connected, the probe 1031 is used to penetrate the human body subcutaneously to detect analyte parameter information, and those skilled in the art can understand that the analyte here includes but is not limited to blood sugar, and can also be chemical substances that may exist in human body fluids such as blood protein, dopamine, adrenaline, thyroid hormone, etc. When the probe 1031 detects the above analytes in human body fluids, the electrodes (not shown in the figure) and the membrane system (not shown in the figure) on the probe 1031 will react chemically according to the type and concentration of the analyte, thereby generating electrical signals in different forms, which can be used to indicate the analyte parameter information; the conductive adhesive The strip 1032 contacts the first electrical contact 10121 and forms an electrical connection. The electrical signal generated on the probe 1031 is transmitted to the internal circuit 1012 through the conductive rubber strip 1032 and the first electrical contact 10121. After the internal circuit 1012 performs signal processing such as denoising, amplification, and waveform sorting, the transmitter 1013 transmits the analyte parameter information to the outside world, that is, the transmitter 1013 is electrically connected to the internal circuit 1012; the bottom shell 104 is used to assemble the above-mentioned transmitter unit 101, the sealing ring 102 and the sensor 103, and fix them on the surface of human skin; the battery (not shown in the figure), the battery is sealed in the transmitter unit 101, and is used to provide electrical energy for the transmitter unit 101. Since the battery is sealed in the transmitter unit 101, the transmitter unit 101 can be used in a humid or underwater environment, thereby enhancing the user experience.

[0061] Combination Figure 2 , Figure 2 Schematic diagram of the cross-sectional structure of the analyte detection system according to an embodiment of the present invention.

[0062] The probe 1031 includes an in-vivo part 10311 and an in-vitro part 10312. The in-vivo part 10311 includes at least a working electrode and a reference electrode (not shown in the figure), and a membrane system (not shown in the figure). In an embodiment of the present invention, the analyte to be detected is glucose, and glucose oxidase is applied to the working electrode and the membrane surface. The glucose in the human body fluid produces hydrogen peroxide H2O2 under the catalytic reaction of glucose oxidase, and at the same time produces electrons. The number of electrons produced by different concentrations of glucose is different, thereby obtaining a continuous change in current intensity, that is, electrical signals in different forms, which are used to indicate analyte parameter information. The in-vitro part 10312 is bent toward the surface of the sensor 103, and forms a bending angle α relative to the in-vivo part 10311. Preferably, the bending angle α=90°. The in-vitro part 10312 is a planar structure, and is in electrical contact with the conductive rubber strip 1032 to conduct the electrons generated by the in-vivo part 10311 to the conductive rubber strip 1032.

[0063] In the embodiment of the present invention, the conductive rubber strip 1032 is formed by alternately layering conductive silicone and insulating silicone and then vulcanizing and stacking, that is, the conductive rubber strip 1032 has a conductive area and an insulating area. One side of the conductive rubber strip 1032 is in electrical contact with the external part 10312, and the other side is in electrical contact with the first electrical contact 10121. In this way, on the one hand, the electrical signal indicating the analyte parameter information can be transmitted to the internal circuit 1012 through the conductive area of ​​the conductive silicone, and on the other hand, the electrical signals obtained by different electrodes can be transmitted to different first electrical contacts 10121 in an insulated manner. In other references, the conductive rubber strip 1032 is also called a "zebra strip", which has stable and reliable performance, simple and efficient production and assembly, and the conductive area has good conductivity, and the insulating area also has good insulation.

[0064] Combined with reference Figure 1 and Figure 2 , when the bottom shell 104 is fixed on the surface of the user's human skin and the internal part 10311 penetrates the subcutaneous tissue, the analyte detection system 10 is in an operable state. In the operable state, the user can set parameters such as the analyte detection interval, the analyte detection type, and the analyte concentration alarm threshold. It can be understood by those skilled in the art that the user-operable functions should not be limited to the above contents, but may also include other functions that can be operated by the user to enhance the user experience, such as the user can calibrate the sensor, activate or stop the sensor, turn on or off the alarm, connect or disconnect the remote device, switch the user's physical state, start an event, end an event, etc.

[0065] Figure 3 Functional schematic diagram of the motion sensor and internal circuitry.

[0066] The motion sensor 1014 is operably connected to the internal circuit 1012 so as to transmit command signals between the two. Here, "operably connected" means that the internal circuit 1012 can directly obtain body movement information from the motion sensor 1014, or can indirectly obtain user body movement information from the motion sensor 1014, and control the sensor 103 or the transmitter 1013 to execute the corresponding function instruction.

[0067] Preferably, in the embodiment of the present invention, the motion sensor 1014 is electrically connected to the internal circuit 1012. The electrical connection between the two not only facilitates the structural design, but also reduces power consumption.

[0068] As described above, the sensor 103 and the transmitter 1013 are electrically connected to the internal circuit 1012 respectively. The internal circuit 1012 is divided into a first subcircuit 10121 connected to the sensor 103 and a second subcircuit 10122 connected to the transmitter 1013. The first subcircuit 10121 and the second subcircuit 10122 can operate independently or interactively, so the internal circuit 1012 can control the sensor 103 and the transmitter 1013 to execute corresponding functional instructions separately or simultaneously.

[0069] In other embodiments of the present invention, the sensor 103 and the transmitter 1013 are wirelessly connected to the internal circuit 1012 respectively, that is, the sensor 103 is wirelessly connected to the first sub-circuit 10121, and the transmitter 1013 is wirelessly connected to the second sub-circuit 10122. The first sub-circuit 10121 and the second sub-circuit 10122 can operate independently or interactively, so the internal circuit 1012 can control the sensor 103 and the transmitter 1013 separately or simultaneously to execute corresponding functional instructions.

[0070] In an embodiment of the present invention, the functional instructions include functions that can be executed by the sensor 103, such as but not limited to sensor calibration, sensor activation or stop, and adjustment of the blood glucose concentration alarm threshold; they also include functions that can be executed by the transmitter 1013, such as but not limited to adjusting signal strength, turning on / off signal transmission, and connecting / disconnecting a remote device; they also include functions that can be executed by both the sensor 103 and the transmitter 1013, such as but not limited to switching the user's physical state, event start, and event end.

[0071] It should be noted that the blood glucose concentration alarm threshold is used to warn the user when the blood glucose is too high or too low. Connecting or disconnecting a remote device means that the user can choose whether to connect the sensor 103 or the transmitter 1013 to the remote device according to actual needs. Switching the user's physical state means that the user switches from a sitting state to a sleeping state, or the user switches from a sleeping state to a waking state, etc. Event start indicates a user's dining event, exercise event, or bathing event, etc.

[0072] The function performed by the analyte detection system controlled by body movements in the embodiment of the present invention is controlled by the body movements of the user. Therefore, in the embodiment of the present invention, different body movements of the user represent different functional instructions.

[0073] In the embodiment of the present invention, the body movements include walking, jumping, running, squatting, leg movements, arm movements, bending, body twisting, and / or tapping, shaking, and pressing the motion sensor 1014. Compared with manual input, body movements are easier to implement and provide a better user experience.

[0074] It should be noted here that tapping, shaking, and pressing the motion sensor 1014 includes not only direct contact with the motion sensor 1014, but also indirect contact or no contact, such as the user can tap, shake, and press the motion sensor 1014 through clothing. Leg movements include but are not limited to lifting legs and shaking legs. Arm movements include but are not limited to shaking arms, swinging arms, and swinging arms. Walking includes but is not limited to moving forward and backward, walking in circles, and walking forward in a zigzag pattern.

[0075] In an embodiment of the present invention, the functional instruction is one or a combination of multiple physical movements, and the number of physical movements performed is not limited. For example, in an embodiment of the present invention, the functional instruction for calibrating the sensor 103 is to tap the motion sensor 1014 three times. Tapping three times instead of once, twice or more than three times avoids interference caused by accidental physical movements, and is more convenient than tapping more than three times, thereby enhancing the user experience.

[0076] In another embodiment of the present invention, the functional instruction for connecting / disconnecting a remote device (such as a handheld device, a mobile phone, a tablet, etc.) is that the user bends down once and then twists the body twice.

[0077] In another embodiment of the present invention, the functional instruction for activating the sensor 103 is to tap the motion sensor twice and then press the motion sensor twice; the functional instruction for stopping the sensor 103 is to tap the motion sensor once and then press the motion sensor three times.

[0078] Combination Figure 1 In order to enrich the body movements that can be used by users and enhance the user experience, the slapping, shaking, and pressing of the motion sensor 1014 in different directions can also be used to set functional instructions. In one embodiment of the present invention, the functional instruction for adjusting the signal strength of the transmitter 1013 is to slap the motion sensor 1014 four times in the positive direction of the X-axis, which can enhance the signal strength of one gear, and slap the motion sensor 1014 four times in the reverse direction of the X-axis, which can reduce the signal strength of one gear. In another embodiment of the present invention, slapping the motion sensor 1014 four times in the positive direction of the Y-axis can enhance the signal strength of two gears, and slapping the motion sensor 1014 four times in the reverse direction of the Y-axis can reduce the signal strength of two gears. In another embodiment of the present invention, slapping the motion sensor 1014 four times in the positive direction of the Z-axis can enhance the signal strength of three gears, and slapping the motion sensor 1014 four times in the reverse direction of the Z-axis can reduce the signal strength of three gears.

[0079] In order to avoid interference caused by redundant or erroneous body movements of the user, the user needs to complete the body movement corresponding to the expected instruction within a fixed time t, where the fixed time t can be set to any time within 0.5~5s according to the user's habits, preferably, t=1s. For example, in an embodiment of the present invention, the user taps the motion sensor 1014 three times within 1s, which is a valid body movement, in the expectation of executing the functional instruction of the calibration sensor 103, but due to external factors, the user taps the motion sensor 1014 once more after 1s, which is an invalid body movement. If there is no limit on the fixed time t, this body movement combination will be recognized as adjusting the signal strength of the transmitter 103.

[0080] Those skilled in the art will appreciate that the limb movements or limb movement combinations corresponding to the above-mentioned functional instructions are not unique, and users can set the limb movements or limb movement combinations corresponding to each functional instruction according to their own habits and conditions.

[0081] Figure 4a-4b Schematic diagram of the functions of the analyte detection system including the action confirmation module 205 according to different embodiments of the present invention.

[0082] The action confirmation module 205 is connected to the motion sensor 2014 to confirm whether the user's body movements meet the requirements (such as the set speed, intensity or frequency, etc.) to improve the accuracy of the analyte detection system. When the motion sensor 2014 detects a specific body movement of the user, but the body movement does not meet the set requirements, the analyte detection system will issue a specific form of alarm (such as light, sound, vibration, etc.) to enable the user to make a more standard body movement again. Similarly, when the body movement meets the requirements, the analyte detection system can also issue a specific form of prompt (such as light, sound, vibration, etc.).

[0083] The embodiment of the present invention does not impose any specific restrictions on the location of the action confirmation module 205 and the connection relationship with other modules, as long as the conditions for connecting the action confirmation module 205 to the motion sensor 2014 are met. Preferably, in the embodiment of the present invention, the action confirmation module 205 is arranged between the motion sensor 2014 and the internal circuit 2012, such as Figure 4a As shown. Therefore, when the motion sensor 2014 senses and identifies the user's body movement, the action confirmation module 205 confirms whether the action meets the requirements. If it meets the requirements, the internal circuit 2012 indirectly receives the body movement instruction information sensed by the motion sensor 2014, and controls the sensor 203 or the transmitter 2013 to execute the corresponding function instruction. At this time, the motion sensor 2014 and the internal circuit 2012 are operably connected.

[0084] In another embodiment of the present invention, the action confirmation module 205 may also be connected only to the motion sensor 2014, such as Figure 4b When the action confirmation module 205 confirms that the limb action meets the requirements, the internal circuit 2012 can directly obtain the corresponding instruction and control the sensor 203 or the transmitter 2013 to execute the corresponding function instruction.

[0085] The principle and method of the internal circuit 2012 controlling the sensor 203 and the transmitter 2013 are described above and will not be repeated here.

[0086] Figure 5 This is a functional schematic diagram of another embodiment of the present invention, in which the internal circuit 3012 includes a first sub-circuit 30121 and a second sub-circuit 30122 .

[0087] In the embodiment of the present invention, the first subcircuit 30121 controls the sensor 303, the second subcircuit 30122 controls the transmitter 3013, the first subcircuit 30121 is electrically connected to the second subcircuit 30122 to transmit the analyte parameter information detected by the sensor 303 to the transmitter 3013, and the motion sensor 3014 is electrically connected to the first subcircuit 30121 and the second subcircuit 30122 respectively. If the body movement is a functional instruction about the sensor 303, then when the motion sensor 3014 senses the body movement of the user, the signal generated by the motion sensor 3014 is recognized by the first subcircuit 30121, but cannot be recognized by the second subcircuit 30122, and the first subcircuit 30121 controls the sensor 303 to execute the corresponding functional instruction; if the body movement is a functional instruction about the transmitter 3013, then when the motion sensor 3014 senses the body movement of the user, the signal generated by the motion sensor 3014 is recognized by the second subcircuit 30122, but cannot be recognized by the first subcircuit 30121, and the second subcircuit 30122 controls the transmitter 3013 to execute the corresponding functional instruction. In this way, the accuracy of the analyte detection system for body movement recognition can be further improved.

[0088] In other embodiments of the present invention, the first sub-circuit 30121 is wirelessly connected to the second sub-circuit 30122, and the motion sensor 3014 is electrically connected to the first sub-circuit 30121 and the second sub-circuit 30122, respectively.

[0089] In yet another embodiment of the present invention, the first sub-circuit 30121 is wirelessly connected to the second sub-circuit 30122, and the motion sensor 3014 is wirelessly connected to the first sub-circuit 30121 and the second sub-circuit 30122, respectively.

[0090] Figure 6This is a functional schematic diagram of a motion sensor 4014 including a first sub-motion sensor 40141 and a second sub-motion sensor 40142 according to yet another embodiment of the present invention.

[0091] In the embodiment of the present invention, the internal circuit 4012 includes a first sub-circuit 40121 and a second sub-circuit 40122. The first sub-motion sensor 40141 is connected to the sensor 403 through the first sub-circuit 40121, and the second sub-motion sensor 40142 is connected to the transmitter 4013 through the second sub-circuit 40122. The first sub-motion sensor 40141 stores the body motion data corresponding to the function instruction of the sensor 403, and the second sub-motion sensor 40142 stores the body motion data corresponding to the function instruction of the transmitter 4013. When the user issues a body motion corresponding to the function instruction of the sensor 403, the first sub-motion sensor 40141 can recognize and generate a signal, which is transmitted to the first sub-circuit 40121. The first sub-circuit 40121 controls the sensor 403 to complete the corresponding function instruction. At this time, the second sub-motion sensor 40142 cannot recognize the body motion, so it will not generate a signal, and will not be transmitted to the second sub-circuit 40122. When the user issues a body movement corresponding to the function instruction of the transmitter 4013, the second sub-motion sensor 40142 can recognize it and generate a signal, which is transmitted to the second sub-circuit 40122. The second sub-circuit 40122 controls the transmitter 4013 to complete the corresponding function instruction. At this time, the first sub-motion sensor 40141 cannot recognize the body movement, so it will not generate a signal, and will not be transmitted to the first sub-circuit 40121. In this way, the accuracy of the analyte detection system for body movement recognition can be further improved, and the power consumption of the system can also be reduced.

After signal processing such as denoising, amplification, and waveform arrangement, the transmitter 5013 transmits the analyte parameter information to the outside, that is, the transmitter 5013 is electrically connected to the internal circuit 5012; the bottom shell 504 is used to assemble the above-mentioned transmitter unit 501, the sealing ring 502 and the sensor 503, and fix them on the surface of human skin.
