TECHNICAL FIELD

The invention mainly relates to the field of medical devices, in particular to an energy-efficient analyte detection system.

DESCRIPTION OF RELATED ART

The pancreas in a normal human body can automatically monitor the blood glucose level and automatically secrete required amount of insulin/glucagon. In the body of a type 1 diabetes patient, the pancreas does not function properly and cannot produce enough insulin for the body. Therefore, type 1 diabetes is a metabolic disease caused by abnormal pancreatic function, and diabetes is a lifelong disease. At present, there is no cure for diabetes with medical technology. The onset and development of diabetes and its complications can only be controlled by stabilizing blood glucose.

Diabetics need to have their blood glucose measured before they inject insulin into the body. At present, most of the testing methods can continuously measure blood glucose level and transmit the data to a remote equipment in real time for the user to view. This method is called Continuous Glucose Monitoring (CGM).

Due to the need for miniaturization design, the batteries placed inside the analyte detection device are not too large, so the battery capacity is not too large. When using the analyte detection device, the battery's endurance needs to be considered. Existing analyte detection devices transmit signals to the outside world after leaving the factory, and users have handheld devices search for these broadcast signals to complete pairing and establish communication connections, this way of transmitting signals after leaving the factory will consume too much energy from the battery, making it difficult to meet the long-term usage needs of the analyte detection device.

DESCRIPTION OF THE EMBODIMENTS

As mentioned earlier, existing analyte detection devices transmit signals to the outside world after leaving the factory. Users can use handheld devices to search for these broadcast signals to complete pairing and establish communication connections. This way of transmitting signals after leaving the factory will consume too much battery energy, making it difficult to meet the long-term usage needs of analyte detection devices.

In order to solve this problem, the invention provides an energy-efficient analyte detection system. Before the installation of the analyte detection device, the processor is powered on but in a deep-sleep state, and the transmitter does not transmit signals outward. After the installation of the analyte detection device, the processor switches to a working state and the transmitter starts to transmit signals to the outside world, which can save energy consumption of the battery, Extending the service life of analyte detection devices.

It should be noted that similar labels and letters indicate similar items in the appending drawings below, so that once an item is defined or described in one of the appending drawings, there is no need to discuss it further in the subsequent appending drawings.

FIG. 1 is a structural diagram of the analyte detection system in an embodiment of the invention. The analyte detection system 10 comprises an auxiliary installer 101 and an analyte detection device 102. The auxiliary installer 101 comprises a housing 1011 and an auxiliary mounting module 1012, which is located inside the housing 1011. Analyte detection device 102 is located at the ejector end of auxiliary mounting module 1012, which enables rapid installation of analyte detection device 102 to the host skin surface when in use.

FIG. 2 is a schematic diagram of the analyte detection device to an embodiment of the invention. The analyte detection device 102 comprises the shell 1021, the sensor 1022, the transmitter 1023, the internal circuit 1024, the battery 1025 and the wake-up module 1026. Sensor 1022 comprises an external part 10221 and an internal part 10222. The external part 10221, transmitter 1023, internal circuit 1024, battery 1025 and wake-up module 1026 are located inside the shell 1021. The internal part 10222 passes through the through-via 10211 on the shell 1021 to the outside to puncture the host subcutaneous and detect the parameter information of analyte. What technicians in this field can know is that in order to pierce the internal part 10222 subcutaneous to the host, the through-via 10211 is located on the side of shell 1021 which is away from housing 1011, and at the same time, a tape (not shown in the figure) is arranged on the surface, which is used to attach the analyte detection device 102 to the skin surface of the host. The external part 10221 is electrically connected with the transmitter 1023 through the internal circuit 1024, which can transmit analyte parameter information to the outside equipment.

Before use, the shell 1021 of the analyte detection device 102 is releasable connected with the housing 1011 of auxiliary mounting device 101. Here, “releasable connection” means that shell 1021 is connected with housing 1011 by means of buckle, clamp, etc. Under the action of ejector mechanism of auxiliary mounting module 1012, the shell 1021 can be separated from housing 1011.

After the life of the sensor 1022 has expired, or the battery 1025 has run out of power, or other factors have caused the analyte detection device to fail, the user removes the entire analyte detection device from the skin surface of the host, discards it and replaces it with a new analyte detection device, is beneficial to maintain the best use of the parts of the device.

When analyte detection device 102 is installed on the skin surface of the host and starts to use, communication needs to be established with outside equipment such as PDM (Personal Diabetes Manager), mobile phone, etc., for data interaction, so as to transmit the detected analyte information data in the host to outside equipment.

As mentioned above, the analyte detection device 102 is in dormant state and transmits signal to the outside equipment at the first frequency until communication is formally established with the outside equipment. In the embodiment of the invention, the analyte detection device 102 transmits signal at a lower first frequency to an outside equipment in dormant state to reduce battery energy consumption. In the more preferred embodiment of the invention, the first frequency is 0˜12 times/hour. In the more preferred embodiment of the invention, the first frequency is 0 times/hour, that is, the analyte detection device 102 does not transmit signal to the outside equipment in dormant state.

In order to establish communication between the analyte detection device 102 which is in dormant state and outside equipment, wake-up module 1026 wakes up analyte detection device 102 according to triggering conditions, so that it enters the working state and transmits signal to the outside equipment with the second frequency, and then communication is established after the outside equipment responds. The second frequency is higher than the first frequency in order to obtain analyte parameter information conveniently and in real time. In the preferred embodiment of the invention, the second frequency is 12˜3600 times/hour. In a more preferred embodiment of the invention, the second frequency is 30 times/hour.

First Embodiment

Light Sensing Element

FIG. 3a is a schematic diagram of the structure of the wake-up module of the analyte detection device comprising a light sensing element in an embodiment of the invention. FIG. 3b is a functional schematic diagram of the wake-up module of the analyte detection device comprising the light sensing element in an embodiment of the invention.

In the embodiment of the invention, the wake-up module 1026 comprises a light sensing element 10261, such as photoelectric switch, which is in open state when there is no light beam or weak light beam irradiation and in a closed state when there is light beam irradiation.

In combination with FIG. 1 and FIG. 3b, transmitter 1023 is connected with battery 1025 through internal circuit 1024, forming a closed loop. The circuit is connected with a wake-up module 1026, which is connected with a light sensing element 10261 inside. The triggering condition of the wake-up module 1026 is the light intensity change received by the light sensing element 10261. In the preferred embodiment of the invention, the triggering condition of the wake-up module 1026 is that the light intensity received by the light sensing element 10261 changes from weak to strong.

In the embodiment of the invention, the analyte detection device 102 is not separated from the auxiliary mounting device 101 before it is installed on the skin surface of the host, and the shell 1021 and housing 1011 form a closed and opaque space. Since the light-transmitting area 10211 is located near the end of the housing 1011, there is no external light irradiates on light sensing element 10261, battery 1025 supplies power to transmitter 1023 through wake-up module 1026 (comprising light sensing element 10261), light sensing element 10261 is in open state, and thus the transmitter 1023 is in dormant state, and analyte detection device 102 transmits signal to outside equipment at the first frequency. After the analyte detection device 102 is installed on the skin surface of the host through the auxiliary mounting module 1012, the shell 1021 is separated from the housing 1011, and the external light can be irradiated to the light sensing element 10261 through the shell 1021. The light sensing element 10261 is in closed state. The transmitter 1023 enters the working state, and the analyte detection device 102 transmits signal to the outside equipment at the second frequency. After the response of the outside equipment, the communication is established and the analyte detection data is transmitted to the outside equipment.

In the embodiment of the invention, the shell 1021 is made of light transmittance material, such as one of polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC) or poly 4-methyl-1-pentene (TPX), and the light transmittance of these material is 40%˜95%. After the separation of shell 1021 and housing 1011, the external light can be irradiated on the light sensing element 10261 through the shell 1021.

In other embodiment of the invention, the shell 1021 comprises light-transmitting area 10211, the light transmittance of the light-transmitting area 10211 is higher than that of the shell 1021, so that more external light is irradiated on the light sensing element 10261, the light intensity variation of the light sensing element 10261 is increased, and the reliability of the light sensing element 10261 is improved.

In another embodiment of the invention, the light-transmitting area 10211 comprises at least one light-transmitting hole, or an array combination of several light-transmitting holes. The light-transmitting hole can make more external light illuminate on the light sensing element 10261, further increase the light intensity variation of the light sensing element 10261, and improve the reliability of the light sensing element 10261. A light-transmittance film is arranged in the light-transmitting hole (not shown in the figure), which can prevent external water droplets, dust and other dirt from inputting the analyte detection device through the light-transmitting hole and improve the reliability of the device.

In the embodiment of the invention, the light sensing element 10261 can sense visible light or invisible light, such as infrared or ultraviolet light. In the preferred embodiment of the invention, the light sensing element 10261 senses visible light so that the user can wake up the analyte detection device indoors or outdoors.

In other embodiment of the invention, the switch condition of open circuit and closed circuit of the light sensing element is low light irradiation to strong light irradiation, that is, before the separation of shell 1021 and housing 1011, weak external light is allowed to illuminate the interior of housing 1011, and the light sensing element 10261 receives weak light, but it is still in open circuit and the transmitter 1023 is in dormant state, which takes into account that the actual connection between shell 1021 and housing 1011 is not completely sealed. When the shell 1021 is separated from the housing 1011, the external light completely irradiates on the light sensing element 10261 through the shell 1021, and the light intensity received by the light sensing element 10261 becomes stronger. After reaching the set light intensity threshold, the light sensing element 10261 switches to the closed state, and the transmitter 1023 enters the working state to transmit signal to the outside equipment at the second frequency. After the response from the outside equipment, the communication is established and the analyte detection data is transmitted to the outside equipment.

Second Embodiment

Magnetic Component and Magnetic Induction Element

FIG. 4a is a schematic diagram of the structure of the analyte detection system comprising

magnetic component and magnetic induction element in an embodiment of the invention. FIG. 4b is a schematic diagram of the structure of the wake-up module of the analyte detection device comprising the magnetic induction element in an embodiment of the invention. FIG. 4c is a schematic diagram of the function of the wake-up module of the analyte detection device comprising the magnetic induction element in an embodiment of the invention.

In the embodiment of the invention, a magnetic component 203 is arranged on the housing 2011, and a magnetic induction element 20261 is arranged in the wake-up module 2026, the battery 2025 supplies power to transmitter 2023 through the wake-up module 2026 (comprising the magnetic induction element 20261). Magnetic component 203 provides a stable magnetic field, and magnetic induction element 20261 is located in the magnetic field of magnetic component 203 and induces the magnetic field of magnetic component 203 to generate a signal. The triggering condition of the wake-up module 2026 is the magnetic field change induced by the magnetic induction element 20261.

The transmitter 2023 is connected with the battery 2025 through the internal circuit 2024, forming a closed loop, and the circuit is connected with the wake-up module 2026. Before the analyte detection device 202 is installed on the skin surface of the host, the analyte detection device 202 is not separated from the auxiliary mounting device 201, and the relative position is fixed. The magnetic field induced by the magnetic induction element 20261 to the magnetic component 203 is stable. Under the stable magnetic field, the magnetic induction element 20261 is in the open state, the transmitter 2023 is in dormant state, and analyte detection device 202 transmits signal to outside equipment at the first frequency. After the analyte detection device 202 is installed on the skin surface of the host through the auxiliary mounting module 2012, the shell 2021 is separated from the housing 2011, and the distance between the magnetic induction element 20261 and the magnetic component 203 changes, so the induced magnetic field also changes, and the magnetic induction element 20261 switches to the closed state, and transmitter 2023 enters the working state. Analyte detection device 202 transmits signal to the outside equipment at the second frequency, and then establishes communication with outside equipment after the response of the outside equipment, and transmits analyte detection data to the outside equipment.

In the embodiment of the invention, the magnetic induction element 20261 senses the magnetic field strength or magnetic field direction of the magnetic component 203. Preferably, the induction element 20261 comprises a hall element (not shown in the figure) that sensitively sensitizes the magnetic field strength of the magnetic component 203.

In the embodiment of the invention, the magnetic component 203 may be an individual part independent of the housing 2011, or a part of the housing 2011 which is embedded in the housing 2011.

In other embodiments of the invention, the housing 2011 is embedded or enclosed with a magnetic field shielding device (not shown in the figure), such as a Faraday cage. Technicians in this field can know that the magnetic shielding device is located outside the magnetic component 203 to reduce the impact of external magnetic field on the magnetic induction element 20261.

Third Embodiment

Acceleration Sensor

FIG. 5a is a schematic diagram of the structure of the wake-up module of the analyte detection system comprising the acceleration sensor in an embodiment of the invention. FIG. 5b is a schematic diagram of the structure of the wake-up module of the analyte detection device comprising the acceleration sensor in an embodiment of the invention. FIG. 5c is a schematic diagram of the function of the wake-up module of the analyte detection device comprising the acceleration sensor in an embodiment of the invention.

In the embodiment of the invention, the wake-up module 3026 comprises an acceleration sensor 30261, which can sensitively sense the values of motion parameters such as acceleration and adjust the circuit state of the wake-up module 3026 accordingly. The triggering condition of wake-up module 3026 is the motion parameter change of acceleration sensor 30261.

Transmitter 3023 is connected with battery 3025 through internal circuit 3024 to form a closed loop, and the circuit is connected with the wake-up module 3026, the battery 3025 supplies power to transmitter 3023 through wake-up module 3026 (comprising acceleration sensor 30261). Before the analyte detection device 302 is installed on the skin surface of the host, the analyte detection device 302 and the auxiliary mounting device 301 are relatively fixed. In order to pierce the internal part of the sensor 30222 of the analyte detection device into the skin of the host and reduce the pain sensation during the stabbing, the auxiliary mounting module 3012 adopts ejector mechanism 30121. Such as spring and other elastic parts, through the auxiliary needle 30122 can quickly pierce the body part 30222 into the host subcutaneous. When the ejector mechanism 30121 is in use, it produces a large instantaneous forward acceleration a1, and when it is installed on the skin surface of the host, it is obstructed by the skin to produce a reverse acceleration a2. After the acceleration sensor 30261 senses the above two accelerations, it can be determined that the analyte detection device 302 is installed on the skin surface of the host.

In the embodiment of the invention, before the analyte detection device 302 is installed on the skin surface of the host, the wake-up module 3026 is in an open state, and the transmitter 3023 is in a dormant state and transmits signal to the outside equipment at the first frequency. Acceleration sensor 30261 determines that the analyte detection device 302 is installed on the skin surface of the host, and the wake-up module 3026 switches to the closed state, and transmitter 3023 enters the working state and transmits signal to the outside equipment at the second frequency. After the response of the outside equipment, the communication is established and the analyte detection data is transmitted to the outside equipment.

It can be understood by those skilled in the art that “first frequency” and “second frequency” in this patent refer to the transmission frequency of the signal to characterize the transmission interval of the signal.

FIG. 6 is a schematic diagram of the communication connection between the analyte detection device and remote equipment according to the embodiment of the invention.

In the embodiment of the invention, the analyte detection device 102 is activated after inputting the working state, transmits the first signal before establishing communication with the remote equipment 103, and transmits the second signal after establishing communication with the remote equipment 103.

In some embodiments of the invention, the first signal uses low-power Bluetooth and the second signal uses near-field communication (NFC). Or the first signal uses WiFi and the second signal uses low-power Bluetooth.

In other embodiments of the invention, the first signal and the second signal are of the same type, but their signal strengths are different. For example, the signal strength of the first signal is weaker than that of the second signal. In the preferred embodiment of the invention, the strengths of the first signal and the second signal are set so that the effective range of the first signal is 0˜10 m and the effective range of the second signal is 0˜10 m. In the more preferred embodiment of the invention, the effective range of the first signal is 0˜1 m, and the smaller effective range of the first signal is convenient for the remote equipment 103 to filter the fault first signal.

In other embodiments of the invention, the first signal and the second signal have different signal formats, for example, the communication connection status of the first signal packet is marked as A, and the communication connection status of the second signal packet is marked as B. The above mark can be located at any position of the packet, such as the packet header or the packet body, and so on. In a preferred embodiment of the invention, the packet header is set as the communication connection status flag bit. When the communication connection is not established, the first signal packet sent by the analyte detection device is A⋅⋅⋅ while the communication connection is established, the second signal packet sent by the analyte detection device is B⋅⋅⋅. In another preferred embodiment of the invention, a plurality of flag bits are set as communication connection status mark. In the state of no communication connection, the first signal packet sent by the analyte detection device is A⋅⋅⋅A⋅⋅⋅A⋅⋅⋅, and in the state of established communication connection, the second signal packet sent by the analyte detection device is B⋅⋅⋅B⋅⋅⋅B⋅⋅⋅. As long as the communication connection status of the analyte detection device can be distinguished, the number of flag bits and format of the data packet are not limited. In this embodiment, the form of the communication connection status mark A (B) in the data packet can be a single byte, such as 0 (1), or a multi byte, such as 000 (111), which is not limited here.

In other embodiments of the invention, the first signal and the second signal have different signal frequencies, for example, the first signal is the low-frequency signal and the second signal is the high-frequency signal, or the first signal is the high-frequency signal and the second signal is the low-frequency signal. Wherein, the first signal is the low-frequency signal and the second signal is the high-frequency signal, which is only used to explain that the frequency of the first signal is lower than the second signal, rather than to limit the specific frequency of the first signal and the second signal. Similarly, the first signal is the high-frequency signal and the second signal is the low-frequency signal, which is only used to explain that the frequency of the first signal is higher than the second signal, rather than to limit the specific frequency of the first signal and the second signal.

In other embodiments of the invention, the difference between the first signal and the second signal lies in the signal format and signal strength, or in the signal format and signal strength, the signal frequency, or a combination of other signal difference forms. The combination of various different forms of signals is more conducive to the remote equipment to distinguish the analyte detection device to be connected.

As long as the first signal can be distinguished from the second signal, the technical scheme comprising but not limited to the above can be adopted, which is not limited here. No matter how the first signal and the second signal are distinguished, the characteristics of the first signal and the second signal are pre stored in the remote equipment 103.

In the embodiment of the invention, the second signal also includes at least the scanning signal and the real-time signal, that is, after the analyte detection device 102 establishes communication connection with the remote equipment 103, they execute a data interaction program. Here, the data interaction program can be that the analyte detection device 102 sends the real-time in vivo analyte parameter information to the remote equipment 103 at a fixed time interval, or when the remote equipment 103 is close to the analyte detection device 102, the communication connection with the remote equipment 103 is re-established. At this time, the analyte detection device 102 sends the in vivo analyte parameter information to the remote equipment 103. The specific scheme will be described in detail below.

In the embodiment of the invention, after the remote equipment 103 establishes communication connection with the analyte detection device 102, the user can select a scanning program or a real-time program in the remote equipment 103.

For example, when the user needs to monitor the blood glucose information in the body in real time during the day when he/she has a normal work, rest and diet, the user selects a real-time program, and the analyte detection device 102 sends the blood glucose concentration information in the body to the remote equipment 103 at a fixed time interval for the user, so that the user can adjust the work, rest and diet. In the preferred embodiment of the invention, the analyte detection device 102 sends in vivo blood glucose concentration information to the remote equipment 103 at a time interval of 2 min.

For another example, when the user cannot know the real-time blood glucose concentration information after entering sleep at night, the user selects the scanning program. During sleep, the analyte detection device 102 does not send the blood glucose concentration information to the remote equipment 103. After the user wakes up, the remote equipment 103 is close to the analyte detection device 102, and the analyte detection device 102 sends the blood glucose concentration information to the remote equipment 103. Generally, after the user selects the scanning program, the effective distance of the signal sent by the analyte detection device 102 is very short, for example, 0˜1 m, or even 0˜0.1 m, or 0˜0.01 m. A shorter effective distance of the signal can prevent the user from misoperation and improve the user experience.

In the embodiment of the invention, the user completes the switching between the scanning program and the real-time program by inputting or adjusting the control command on the remote equipment 103. When switching the data interaction program, the remote equipment 103 has established the communication connection with the analyte detection device 102.

In the embodiment of the invention, the power of the analyte detection device 102 transmitting the scanning signal is lower than the power of the real-time signal, so that the effective distance of the scanning signal is less than the effective distance of the real-time signal. When the user uses the real-time program, the remote equipment 103 is held in his hand or placed on the table, and will not deliberately close to the analyte detection device 102 installed on his arm or waist, so the two signals will not interfere, the reliability of real-time signal is guaranteed. In the preferred embodiment of the invention, the effective distance of the real-time signal is 0˜10 m to ensure that the user can maintain the communication connection between the remote equipment 103 and the analyte detection device 102 during daily use.

In the embodiment of the invention, the power of the real-time signal or the scanning

signal can be adjusted according to the communication distance of the signal. For example, when using the real-time program, it is not convenient for the user to carry the remote equipment 103 when bathing, but the remote equipment 103 needs to be placed away from the bathing place, or even in another room. At this time, it is necessary to appropriately increase the power of the signal to increase the effective distance of the signal, so that the remote equipment 103 can maintain the communication connection with the analyte detection device 102. After bathing, the user can hold the remote equipment 103, at this time, the power of the signal can be reduced. While the remote equipment 103 maintains the communication connection with the analyte detection device 102, the energy consumption of the battery can be reduced. In the embodiment of the invention, the adjustment of signal power can be manually adjusted by the user or automatically adjusted by the analyte detection device 102.

In the embodiment of the invention, when the remote equipment 103 is within the effective distance of the signal, the remote equipment 103 establishes the communication connection with the analyte detection device 102, and when the remote equipment 103 is outside the effective distance of the signal, the remote equipment 103 disconnects the communication connection with the analyte detection device 102. For example, when the user uses the scanning program, the remote equipment 103 is located outside the effective distance of the signal, and the remote equipment 103 disconnects the communication connection with the analyte detection device 102. At this time, there is no data interaction between the remote equipment 103 and the analyte detection device 102, which can reduce the energy consumption of the battery. When the remote equipment 103 enters the effective distance of the signal, the remote equipment 103 re-establishes the communication connection with the analyte detection device 102. For another example, when the user uses the real-time program, when the user exercises, the remote equipment 103 will generally not be carried with him, and the remote equipment 103 will maintain a long distance from the analyte detection device 102. At this time, the remote equipment 103 disconnects the communication connection with the analyte detection device 102. After exercising, the remote equipment 103 will be carried, and the remote equipment 103 will enter the effective distance of the signal, the remote equipment 103 re-establishes the communication connection with the analyte detection device 102.

In the embodiment of the invention, when the user uses the scanning program, in the normal time, the remote equipment 103 and the analyte detection device 102 are in the disconnected communication connection state. When the user operates the remote equipment 103 to approach the analyte detection device 102 every time, for example, 4 cm, the remote equipment 103 searches for the signal transmitted by the analyte detection device 102 and re-establishes the communication connection with the analyte detection device 102. The analyte detection device 102 interacts with the remote equipment 103 and sends the in vivo analyte parameter information to the remote equipment 103. Here, the analyte detection device 102 can interact with the remote equipment 103 once or many times. Generally, when the user selects to use the scanning program, the time for the remote equipment 103 to approach the analyte detection device 102 is very short. Therefore, it is preferred that the analyte detection device 102 conduct a data interaction with the remote equipment 103. When the analyte detection device 102 interacts with the remote equipment 103, it can transmit historical analyte parameter information, such as the data set in the past hour, or real-time analyte parameter information, or historical analyte parameter information with real-time analyte parameter information at the same time, which is not limited here. In the embodiment of the invention, when the user uses the real-time program, in the normal time, the remote equipment 103 and the analyte detection device 102 are in the communication connection state, and the analyte detection device 102 sends the analyte parameter information to the remote equipment 103 at a fixed time interval, such as 2 min. The specific time interval is not specifically limited here.

In the embodiment of the invention, the effective distance of the scanning signal is less than the effective distance of the real-time signal. Generally, the two signals will not interfere, but in some complex environments, such as in the hospital ward, multiple patients use the analyte detection device, resulting in the presence of multiple scanning signals or real-time signals in a narrow space, and there is a low probability of signal interference, which is detrimental to patients. To avoid this, scanning signals and real-time signals can also be distinguished by signal frequency, signal type or/and signal format. In a preferred embodiment of the invention, the scanning signal and the real-time signal have different signal formats. For example, the mark of the scanning signal packet is C, and the mark of the real-time signal packet is D. The above mark can be located at any position of the data packet, such as the packet header, or the packet body, and so on. In a preferred embodiment of the invention, the packet header of the data packet is set as a marker bit to distinguish between the scanning signal and the real-time signal. In another preferred embodiment of the invention, a plurality of marker bits of the data packet are set as the marker bits to distinguish the scanning signal and the real-time signal. When using the scanning program, the scanning signal data packet sent by the analyte detection device is C⋅⋅⋅C⋅⋅⋅C⋅⋅⋅. And when using the real-time program, the real-time signal data packet sent by the analyte detection device is D⋅⋅⋅D⋅⋅⋅D⋅⋅⋅. As long as the scanning signal and the real-time signal can be distinguished, the number of tag bits and format of the data packet are not limited. In this embodiment, the form of scanning signal and real-time signal distinguishing mark C (D) in the data packet can be single byte, such as 0 (1), or multi byte, such as 000 (111), which is not limited here.

In the embodiment of the invention, the analyte detection device 102 may re-establish the communication connection with the remote equipment 103 many times within its service life. In some complex environments, such as in the hospital ward, the signals between multiple devices may be disturbed, and the user may receive error signals from other devices when preparing to establish the communication connection between the remote equipment 103 and the analyte detection device 102, In order to avoid this possible situation, before the remote equipment 103 establishes the communication connection with the analyte detection device 102, the remote equipment 103 sends a prompt that needs to be confirmed by the user. For example, the device code and other features of the analyte detection device 102 that is about to establish the communication connection are displayed on the remote equipment, and the communication connection can be formally established only after the user confirms.

In the embodiment of the invention, once the analyte detection device 102 establishes the communication connection with the remote equipment 103 for the first time, the analyte detection device 102 is stored as a white list device of the remote equipment 103, and its signal characteristics are recorded by the remote equipment 103 at the same time. When searching for nearby signals, the remote equipment 103 can only recognize the signals transmitted by the recorded white list device and establish the communication connection with the white list device, which can avoid the interference of other device signals and improve the reliability of the communication connection.

In other embodiments of the invention, the analyte detection device 102 can simultaneously transmit scanning signals and real-time signals. For example, in the hospital, on the one hand, the patient's blood glucose concentration information needs to be transmitted to the doctor's medical management system (remote equipment) to provide doctors with real-time treatment basis. At this time, the analyte detection device 102 needs to interact with the medical management system in real time. On the other hand, the patient also needs to know the blood glucose concentration information in the body when needed, at this time, the patient can get the blood glucose concentration information by putting his PDM or mobile phone close to the analyte detection device 102 on his body to receive the scanning signal.

In the embodiment of the invention, after the remote equipment 103 searches the signal, before establishing the communication connection with the analyte detection device 102, it is necessary to execute a communication data interaction program to match the analyte detection device 102 with the remote equipment 103. The communication data interaction program needs to last for a period of time, and the duration is too short, which is easy to cause user misoperation. For example, some users will install an analyte detection device 102 on their arms and bellies in order to monitor the blood glucose concentration information in their bodies more accurately. Each analyte detection device 102 needs to be connected to the remote equipment 103 to transmit data, so when the user operates to establish the communication connection, it is possible to approach the remote equipment 103 to the wrong analyte detection device 102. For example, the user holds the remote equipment 103 ready to establish the communication connection with the analyte detection device 102 installed on the arm, and when raising his hand, he passes through the analyte detection device 102 installed on the belly, which will establish the wrong communication connection. In this case, by setting the minimum effective time condition for the remote equipment 103 to be close to the analyte detection device 102, such as 2 s, the wrong communication connection caused by misoperation can be avoided. Even if the remote equipment 103 is close to the wrong analyte detection device 102 due to misoperation, it cannot establish the communication connection with the wrong analyte detection device 102 due to insufficient duration, which improves the reliability of the communication connection. If the communication data interaction program lasts too long, on the one hand, it will increase the energy consumption of the battery, on the other hand, the user waiting time is too long, which will affect the user experience. Therefore, it is also necessary to set the maximum effective time condition for the remote equipment 103 to be close to the analyte detection device 102, such as 7 s. That is, when the remote equipment 103 is close to the analyte detection device 102 for not less than 2 s, but not more than 7 s, the remote equipment 103 can normally establish the communication connection with the analyte detection device 102, otherwise it cannot normally establish the communication connection. Those skilled in the art can know that the effective time conditions here are not limited to the time limits described here, but can be adjusted according to the actual product performance, user needs and other conditions.

FIG. 7 is a schematic diagram of the process of establishing communication connection between the analyte detection device and the remote equipment in an embodiment of the invention. Refer to the FIG. 7, in the embodiment of the invention, when the user needs to establish the communication connection between the analyte detection device 102 and the remote equipment 103, first place the remote equipment 103 near the analyte detection device 102 and confirm that there are no other analyte detection devices around as far as possible. After the user starts the remote equipment 103, the remote equipment 103 searches and identifies the nearby signal. If the remote equipment 103 recognizes only one first signal, it can be judged that the signal is the signal transmitted by the analyte detection device 102 to establish the communication connection, and the communication connection with the analyte detection device 102 is established through the link of the signal, without the user manually inputting or scanning the equipment code of the analyte detection device 102, it simplifies the process of establishing communication connection, avoids users from inputting or scanning wrong device code, and improves the user experience.

In other embodiments of the invention, before the analyte detection device 102 establishes the communication connection with the remote equipment 103, the remote equipment 103 prompts the user to confirm whether to connect, so as to improve the reliability of the communication connection between the analyte detection device 102 and the remote equipment 103.

In the embodiment of the invention, if the user is in a complex environment, that is, the remote equipment 103 recognizes multiple first signals, or multiple first signals and second signals, and the remote equipment 103 cannot judge the first signal transmitted by the analyte detection device 102 to establish the communication connection, in this case, the remote equipment 103 prompts the user to manually input or scan the device code of the analyte detection device 102 to establish the communication connection, In order to establish the communication connection with the analyte detection device 102.

In other embodiments of the invention, when the user is in a complex environment, the remote equipment 103 cannot judge the first signal transmitted by the analyte detection device 102 to establish the communication connection, and the remote equipment 103 prompts the user to change the operation location. The user needs to carry the analyte detection device 102 and the remote equipment 103 to other locations until the remote equipment 103 recognizes only one first signal, It can be judged that the signal is the signal transmitted by the analyte detection device 102 to establish the communication connection, and establish the communication connection with the analyte detection device 102 through the link of the signal, without the user manually inputting or scanning the equipment code of the analyte detection device 102, which simplifies the process of establishing the communication connection, avoids the user inputting or scanning the wrong equipment code, and improves the user experience.

In other embodiments of the invention, if the remote equipment 103 does not recognize the first signal within the effective range, it is judged that the analyte detection device 102 is not working normally. At this time, the remote equipment 103 sends an alarm or fault prompt to the user to prompt the user to check or replace the analyte detection device.

In the embodiment of the invention, the prompt of the remote equipment 103 may be one or more of the forms of audio, video or vibration. In one embodiment of the invention, when the prompt of the remote equipment 103 is audio, according to different prompt needs, the remote equipment 103 sends out “tick” prompt tones with different lengths and/or time intervals. In another embodiment of the invention, when the prompt of the remote equipment 103 is video, different text prompts are displayed on the display screen according to different prompt needs. In another embodiment of the invention, when the prompt of the remote equipment 103 is vibration, the remote equipment 103 vibrates with different lengths and/or time intervals according to different prompt needs.

In some embodiments of the invention, the transmitter 1023 includes communication components such as an antenna 10231, which is composed of conductive coils. According to the communication requirements between the analyte detection device 302 and remote equipment, precise design and layout of the conductive coils of the antenna 10231 are required to customize specific characteristics such as inductance, resonance, and loss.

Due to the softness of the conductive coil of the antenna, it needs to be attached to a non-deformable substrate to prevent changes in its inductance and other characteristics during use. According to the substrate material attached to the antenna, it can be divided into ceramic antennas, PCB antennas, and FPC antennas. The ceramic antenna adopts a high and low temperature combined firing method, with conductive coils printed on the ceramic substrate. The formed ceramic antenna takes up less space and has good performance, but the bandwidth is narrow, making it difficult to achieve multi frequency bands. PCB antenna is an antenna based on PCB board, with a specific length of conductive coil fixed on the PCB board. The formed PCB antenna has low cost and does not require separate antenna assembly or repeated debugging. However, PCB antenna is only suitable for a single frequency band, and there may be some deviation between different batches, and it is easily affected by current interference on the PCB board. FPC antenna is based on FPC (Flexible Printed Circuit) as the substrate. FPC antenna has high space utilization, low cost, good performance, and is suitable for small intelligent electronic devices.

However, before use, each FPC antenna needs to be separately debugged, and installation is inconvenient. According to usage requirements, there are also some other types of antennas, such as conductive coils attached to substrates such as plastic or adhesive tape.

In order to reduce the volume and weight of the analyte detection device 102 and improve the user experience, many aspects can be approached.

Referring to FIG. 2, in some embodiments of the invention, a specific length of conductive coil is printed on the circuit board of the internal circuit 1024 as the antenna of the transmitter 1023 (not shown in the figure), achieving the function of transmitting signals to remote equipment and receiving signals. If the antenna on the internal circuit 1024 is transferred and printed on other components of the analyte detection device 102, the circuit board volume of the internal circuit 1024 can be reduced, thereby achieving miniaturization design of the analyte detection device 102.

Referring to FIG. 8a, in some embodiments of the invention, the antenna 10231 is arranged on the outer side of shell of the battery 1025, and the circuit board of the internal circuit 1024 does not need to carry the antenna 10231 anymore. This can reduce the volume of the circuit board occupied by the antenna 10231, thereby achieving a miniaturized design of the analyte detection device 102. Specifically, in the embodiments of the invention, using techniques such as LDS (Laser Direct Structuring), printing, or shell embedding, the conductive coil of antenna 10231 is fixed on the surface of the shell of battery 1025. The antenna 10231 is then connected to the control circuit of transmitter 1023 through a wire (not shown in the figure).

In some embodiments of the invention, the frequency of the transmission and reception signals of antenna 10231 is highly sensitive to the inductance of the conductive coil, and the battery 1025 contains metals and other highly conductive materials, which may cause eddy currents during the operation of antenna 10231. These eddy currents may reduce the inductance of the conductive coil, thereby affecting the working performance of antenna 10231. Therefore, the conductive coils arranged on the surface of shell of the battery 1025 also need to take measures to reduce eddy currents, such as replacing the metal shell of battery 1025 with materials such as PC, ceramics, and PP that can reduce the impact of eddy currents.

In some embodiments of the invention, antenna 10231 is not limited to being arranged on the upper end surface of battery 1025 shown in FIG. 6a, but can also be arranged on the side surface, lower end surface, or part of it is arranged on the upper end surface, and the other part is arranged on the side surface or lower end surface. Those skilled in the art can understand that antenna 10231 is arranged on the outer side of shell of the battery 1025, which can include all surfaces on the outer side of shell of the battery 1025.

Referring to FIG. 8b, in some embodiments of the invention, the antenna 10231 may also be installed on the shell 1021 of the analyte detection device 102. Specifically, in the embodiments of the invention, techniques such as LDS, printing, or shell embedding are used to fix the conductive coil of antenna 10231 on the surface of shell 1021. Preferably, fixing the conductive coil of antenna 10231 on the inner surface of shell 1021 can prevent external dirt from contaminating antenna 10231.

In some embodiments of the invention, the antenna 10231 may be located on the upper shell 10211, or on the lower shell 10212, or partially on the upper shell 10211 and partially on the lower shell 10212, to fully utilize the internal space of the analyte detection device 102. In the embodiment of the invention, when part of the antenna 10231 is located in the upper shell 10211 and the other part is located in the lower shell 10212, the two conductive coils are connected by wires to form a three-dimensional antenna, which can further improve the utilization of the internal space of the shell.

Referring to FIG. 8c, in some embodiments of the invention, the antenna 10231 may also be set on the adhesive tape 104. Specifically, in the embodiments of the invention, techniques such as LDS, printing, or lamination are used to fix the conductive coil of antenna 10231 on the surface or interlayer of adhesive tape 104. Preferably, fixing antenna 10231 in the interlayer of adhesive tape 104 can prevent contamination from external debris.

In some embodiments of the invention, in order to ensure the normal operation of antenna 10231, it may be required to increase the hardness of the adhesive tape 104 appropriately to prevent it from bending or bending due to the user's muscle peristalsis, which may affect the performance of the antenna 10231 arranged on it, and may even damage the antenna 10231.

In some embodiments of the invention, the conductive coil of antenna 10231 can be arranged in a curled manner on the substrate as shown in FIG. 6a-FIG. 6c, or can be arranged on the substrate in fixed angle bending, unfixed angle bending, or other irregular ways. As long as antenna 10231 can achieve its function of transmitting and receiving communication signals at a predetermined frequency, the arrangement of its conductive coil on the substrate is not specifically limited.

In some embodiments of the invention, the conductive coils of antenna 10231 can be arranged on different substrates, for example, a portion is arranged on the outer side of shell of the battery 1025, a portion is arranged on the inner surface of shell 1021 of the analyte detection device 102, or a portion is arranged in the adhesive tape 104, as long as antenna 10231 can achieve its function of transmitting and receiving communication signals at a predetermined frequency, the arrangement position of its conductive coils on the substrate is not specifically limited.

In some embodiments of the invention, the antenna 10231 may consist of multiple conductive coils of the same or different lengths, which are electrically connected to the control circuit of the transmitter 1023 to form multiple antennas that can be used to transmit and receive communication signals of different frequencies.

In some embodiments of the invention, multiple antennas can transmit or receive communication signals simultaneously or at different times through instructions from the control circuit of the transmitter 1023.

In some embodiments of the invention, one of multiple antennas may be set as the main antenna and the other antennas as secondary antennas.

In some embodiments of the invention, when the analyte detection device 102 is in a sleep state, the control circuit of the transmitter 1023 controls the main antenna to transmit signals to the outside world at the first frequency. After the analyte detection device 102 transitions to a working state, the control circuit controls the main antenna to transmit signals to the outside world at the second frequency.

After the analyte detection device 102 transitions to a working state, the control circuit controls the main antenna to transmit signals to the outside world at the second frequency.

In some embodiments of the invention, when the analyte detection device 102 is in a sleep state, the control circuit of the transmitter 1023 controls the main antenna to transmit signals to the outer boundary at the first signal strength. After the analyte detection device 102 transitions to a working state, the control circuit controls the main antenna to transmit signals to the outer boundary at the second signal strength.

After the analyte detection device 102 transitions to a working state, the control circuit controls the main antenna to transmit signals to the outer boundary at the second signal strength. In the embodiments of the invention, the first signal strength is weaker than the second signal strength.

In some embodiments of the invention, multiple antennas may be arranged on the same non circuit board substrate or on different non circuit board substrates.

In some embodiments of the invention, multiple antennas may be arranged in a curled manner on a non-circuit board substrate, or in fixed angle bending, non-fixed angle bending, or other irregular ways on the non-circuit board substrate.

Circuit implementation example for implementing wake-up module 1026 function.

As mentioned above, before the analyte detection device 102 is installed on the surface of the user's skin, in order to prolong the service life of battery 1025 as much as possible and reduce the energy consumption of battery 1025, the analyte detection device 102 is in a dormant state. The analyte detection device 102 is awakened and enters a working state after being installed on the surface of the user's skin through the auxiliary installation module 1012. FIG. 9 shows a circuit implementation example of the wake-up module 1026 that implements the above functions.

In some embodiments of the invention, the electronic components of the wake-up module 1026 circuit include a light sensing element 10261, a processor 10262, a PMOS transistor (field-effect transistor) 10263, a first resistor R1, and a second resistor R2. Each electronic component is operatively connected according to the circuit implementation logic and powered by a battery 1025. Specifically, the a-end of the light sensing element 10261 is connected to the battery 1025 through the resistor R1, the c-end and d-end of the processor 10262 are respectively connected to both ends of the resistor R1, the source of the PMOS transistor 10263 is connected to the battery 1025, the gate is connected to the e-end of the processor 10262, and the drain is connected to the working module. The working module refers to the necessary working components of the analyte detection device 102, including at least antenna 10231, the second resistor R2 is also connected between the source and gate of PMOS transistor 10263, and the b-end of the light sensing element 10261, the g-end of the processor, and the working module are all grounded.

In the embodiment of the invention, the first resistor R1 is a pull-up resistor, and when the light sensing element 10261 is open, the d-end of the processor 10262 is at a high level. The second resistor R2 is the pull-up resistor, which causes the gate (e-end) of the PMOS to be high when processor 10262 is in a deep-sleep state.

The above electronic components are necessary components for the wake-up module 1026 circuit. Technicians in this field should understand that in order to better achieve the function of the circuit, auxiliary components such as voltage stabilizing components can also be added, which will not be explained in detail here.

In the embodiments of the invention, the working module may further include electronic components such as sensor detection circuits, buzzers, LED lights, etc.

In the embodiments of the invention, the light sensing element 10261 can specifically be a photodiode, a photoelectric sensor, a photosensitive resistor, etc. Preferably, the light sensing element 10261 is a photodiode, which has good insulation performance when not exposed to light, and good conductivity when exposed to light.

In the embodiment of the invention, before use, the analyte detection device 102 is fixed inside the auxiliary installer 101, which provides a stable environment for the analyte detection device 102, such as a stable light shielding environment. External light beams cannot penetrate the auxiliary installer 101 to illuminate the analyte detection device 102, in order to prevent the light sensing element 10261 from being triggered. After use, the analyte detection device 102 is separated from the auxiliary installer 101. The auxiliary installer 101 no longer provides a light shielding environment for the analyte detection device. The external beam can shine on the analyte detection device 102 and then on the light sensing element 10261, which is triggered.

The functions of each component in wake-up module 1026 will be explained in detail below.

In some embodiments of the invention, the light sensing element 10261 is in an open circuit state when not illuminated by a beam of light, and the c-end and d-end of the processor 10262 are both at a high level. By setting the resistance value of the first resistor R1, such as 10MΩ, the processor 10262 can have a weak current passing through. That is, after the analyte detection device 102 leaves the factory, the processor 10262 is powered on and in a deep-sleep state. At the same time, the gate of PMOS transistor 10263 is connected to battery 1025 through a second resistor R2, which is in a high-level state. The PMOS transistor 10263 is in an open circuit state, and battery 1025 cannot provide power to the working module.

In some embodiments of the invention, the circuit of the wake-up module 1026 may not include a second resistor R2. When processor 10262 is in a deep-sleep state, the e-end provides a high level for the gate of PMOS transistor 10263, causing PMOS transistor 10263 to be in an open circuit state. After processor 10262 transitions to a working state, the e-end provides a low level for the gate of PMOS transistor 10263, causing PMOS transistor 10263 to be in a closed state.

In some embodiments of the invention, after the analyte detection device 102 leaves the factory, before the light sensing element 10261 is irradiated by a beam of light, the battery 1025 only provides a weak current to the processor 10262. This way, before the official use of the analyte detection device 102, the electronic components will not consume too much energy from the battery 1025, extending the service life of the battery 1025.

In some embodiments of the invention, after the user installs the analyte detection device 102 on the surface of the skin using the auxiliary installer 101, the analyte detection device 102 is separated from the auxiliary installer 101, and the light sensing element 10261 is illuminated by a beam of light and in a closed state. The current flows from a-end to b-end, and the level of the d-end of processor 10262 decreases. At this time, the level of the e-end of processor 10262 decreases, the gate of PMOS transistor 10263 is lowered to a low level, and PMOS transistor 10263 is changed to a closed state. The working module can obtain electricity from battery 1025 and enter the working state. The transmitter 1023 starts to transmit signals to the outside world.

In some embodiments of the invention, once the processor 10262 is converted to a working state, its e-end is continuously controlled to a low level, which can continuously conduct the PMOS transistor 10263. Regardless of whether the light sensing element 10261 can still receive beam illumination afterwards, the battery 1025 can continuously provide power to the working module. After the processor 10262 is converted to a working state, the state of the light sensing element 10261 will not affect the circuit state of the wake-up module 1026.

In some embodiments of the invention, when the working module enters the working state from sleep mode, the electronic components in the working module change from powered off to powered on.

In some embodiments of the invention, after the working module is powered on, before the analyte detection device 102 establishes a communication connection with the remote equipment, the antenna 10231 transmits a signal to the outside at the first signal strength. After the analyte detection device 102 establishes a communication connection with the remote equipment, the antenna 10231 transmits a signal to the outside at the second signal strength, which is weaker than the second signal strength.

In some embodiments of the invention, after the working module is powered on, the sensor detection circuit begins to work, and sensor 1022 is connected to the working current, which can detect the parameter information of the analyte in the user's body.

In some embodiments of the invention, after the working module is powered on, before the analyte detection device 102 establishes a communication connection with the remote equipment, the antenna 10231 transmits signals to the outside world at the first frequency. After the analyte detection device 102 establishes a communication connection with the remote equipment, the antenna 10231 transmits signals to the outside world at the second frequency, with the first frequency lower than the second frequency.

In some embodiments of the invention, the light sensing element 10261 in the wake-up module 1026 can be replaced by other state switching components, such as magnetic sensing components, touch switches, acceleration sensors, etc. After leaving the factory, these state switching components are in an open circuit state, causing processor 10262 to be in a deep-sleep state. After condition triggering, these state switching components change to a closed state, and processor 10262 changes to a working state, the work module begins to work, and the implementation process of the relevant circuits will not be described here anymore.

To sum up, the embodiment of the invention discloses an energy-efficient analyte detection system. Before the installation of the analyte detection device, the processor is powered on but in a deep-sleep state, and the transmitter does not transmit signals outward.
