Abstract
Description
[0001] Cross-reference to related applications
[0002] This application claims the benefit of and priority of the following patent application: PCT patent application filed on September 27, 2021, application number PCT / CN2021 / 120856. Technical Field
[0003] This invention relates primarily to the field of medical devices, and in particular to an analyte detection system and a control method for the analyte detection device. Background Technology
[0004] In a healthy person, the pancreas automatically detects the glucose level in the blood and secretes the necessary insulin / glucagon. However, in diabetic patients, the pancreas malfunctions and cannot secrete the required insulin. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function, and it is a lifelong condition. Currently, medical technology cannot cure diabetes; it can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar levels.
[0005] Diabetic patients need to have their blood glucose levels checked before injecting insulin. Most current testing methods can continuously monitor blood glucose and send the data to external devices in real time for user viewing; this method is called Continuous Glucose Monitoring (CGM).
[0006] Before sending analyte parameter information to external devices, an analyte detection system needs to establish communication with the user's external devices. Current analyte detection systems work by transmitting signals to the external device at intervals before establishing communication. If an external device responds to the signal, communication is established; otherwise, signals are continuously transmitted until communication is established or the battery is depleted. Using this method, the analyte detection system is in working condition from the factory. On the one hand, if the signal transmission interval is too short and the signal transmission frequency is too high, it will result in significant battery energy waste, affecting the lifespan of the analyte detection system. On the other hand, if the signal transmission interval is too long, communication needs to be established during use, resulting in longer waiting times for the user and a poor user experience.
[0007] Therefore, there is an urgent need for an analyte detection system that can establish real-time communication with external devices and reduce battery energy consumption during use. Summary of the Invention
[0008] This invention discloses an analyte detection system and a control method for the analyte detection device. The analyte detection device is in a dormant state before use. When the user uses it, the protective cover of the auxiliary installer is opened, and external light enters the housing of the analyte detection device through the tape and the outer shell, activating the wake-up module and putting the analyte detection device into working state. This can reduce battery energy consumption and extend the service life of the analyte detection device.
[0009] This invention discloses an analyte detection system, comprising: an auxiliary installer, which includes a housing and a protective cover, the protective cover being located at the front end of the housing; and an analyte detection device, which includes a housing, a wake-up module, and adhesive tape, wherein the housing includes an upper housing and a lower housing, and the adhesive tape is fixed to the lower housing for fixing the analyte detection device to the user's skin surface; before using the auxiliary installer, the protective cover is releasably connected to the housing, the analyte detection device is located inside the housing and is in a dormant state, and the lower housing is close to the protective cover; when using the auxiliary installer, the housing and the protective cover are separated, and external light sequentially passes through the adhesive tape and the lower housing to activate the wake-up module, and the analyte detection device enters the working state.
[0010] According to one aspect of the invention, in a dormant state, the analyte detection device transmits a signal to an external device at a first frequency, and in an operating state, the analyte detection device transmits a signal to an external device at a second frequency.
[0011] According to one aspect of the invention, the first frequency is less than the second frequency.
[0012] According to one aspect of the invention, the first frequency is 0 to 12 times / hour, and the second frequency is 12 to 3600 times / hour.
[0013] According to one aspect of the invention, the first frequency is 0 times / hour.
[0014] According to one aspect of the invention, the wake-up module includes a photoelectric switch that switches to a pass state when exposed to external light.
[0015] According to one aspect of the invention, the analyte detection device further includes a sensor, a transmitter, internal circuitry, and a battery, wherein the sensor comprises an external portion and an internal portion, and the external portion, transmitter, internal circuitry, and battery are located within a housing.
[0016] According to one aspect of the invention, the housing and protective cover are made of opaque material, while the adhesive tape and lower outer shell are made of translucent material.
[0017] According to one aspect of the invention, the adhesive tape and the lower outer shell are further provided with a light-transmitting area, through which external light enters the outer shell.
[0018] According to one aspect of the invention, after the auxiliary installer installs the analyte detection device onto the user's skin, the analyte detection device detaches from the housing, and external light redundantly activates the wake-up module through the upper housing.
[0019] According to one aspect of the invention, the upper outer shell is made of a light-transmitting material.
[0020] The present invention also discloses a control method for an analyte detection device, comprising providing an auxiliary installer and an analyte detection device. The auxiliary installer includes a housing and a protective cover, the protective cover being releasably connected to the housing. The analyte detection device includes a shell, a wake-up module, and adhesive tape, wherein the shell includes an upper shell and a lower shell, and the adhesive tape is fixed to the lower shell for fixing the analyte detection device to the user's skin surface. When the protective cover is removed from the housing, external light passes through the adhesive tape and the lower shell in sequence and irradiates the wake-up module, causing the analyte detection device to switch from a dormant state to a working state.
[0021] According to one aspect of the invention, the adhesive tape and the lower housing are further provided with a light-transmitting area, through which external light shines onto the wake-up module.
[0022] According to one aspect of the invention, in a dormant state, the analyte detection device transmits a signal to an external device at a first frequency, and in an operating state, the analyte detection device transmits a signal to an external device at a second frequency.

[0025] According to one aspect of the present invention, in the working state, the analyte detection device establishes a communication connection with external equipment.
[0026] Compared with the prior art, the technical solution of the present invention has the following advantages:
[0027] The analyte detection system disclosed in this invention is in a dormant state before use. When the user uses it, the protective cover of the auxiliary installer is opened, and external light enters the housing of the analyte detection device through the tape and the lower housing, activating the wake-up module and putting the analyte detection device into working state. This can reduce battery energy consumption and extend the service life of the analyte detection device.
[0028] Furthermore, in sleep mode, the analyte detection device transmits signals to external devices at a lower frequency, or does not transmit signals to external devices at all. In working mode, it transmits signals to external devices at the normal operating frequency. This not only avoids wasting battery energy before use, but also allows for real-time communication with external devices during use, thus enhancing the user experience.
[0029] Furthermore, light-transmitting areas are provided on the tape and the lower outer shell. External light shines onto the wake-up module through the light-transmitting areas, which can improve the transmittance of external light and increase the working reliability of the wake-up module.
[0030] Furthermore, after the analyte detection device is installed on the user's skin, external light enters the housing through the upper outer shell, and the wake-up module is activated again. Through redundant activation procedures, the reliability of the wake-up module is increased. Attached Figure Description

[0043] As mentioned earlier, existing analyte detection systems emit signals to the outside world at intervals after leaving the factory. If an external device responds to the signal, communication is established with the external device; otherwise, the system continues to emit signals until communication is established or the battery is depleted. On the one hand, if the signal emission interval is short and the signal emission frequency is high, it will cause a lot of battery energy waste and affect the service life of the analyte detection system. On the other hand, if the signal emission interval is long, the user needs to wait a long time to establish communication, resulting in a poor user experience.
[0044] To address this issue, the present invention provides an energy-saving analyte detection system. The analyte detection device is in a dormant state before use. When the user uses it, the protective cover of the auxiliary installer is opened, and external light enters the housing of the analyte detection device through the tape and the outer shell, activating the wake-up module and putting the analyte detection device into working mode. This can reduce battery energy consumption and extend the service life of the analyte detection device.
[0045] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments should not be construed as limiting the scope of the invention.

Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but where applicable, such techniques, methods, and apparatus should be considered part of this specification.
[0048] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined or described in a figure, it will not need to be discussed further in the subsequent description of the figures.
[0049] Figure 1a This is a schematic diagram of the energy-saving analyte detection system according to an embodiment of the present invention. Figure 1bThis is a schematic diagram of the structure of the energy-saving analyte detection system 10 after the outer shell and protective cover are separated, according to an embodiment of the present invention. The energy-saving analyte detection system 10 includes an auxiliary installer 101, an analyte detection device 102, and a protective cover 103. The auxiliary installer 101 includes a housing 1011 and an auxiliary installer module 1012. In this embodiment, the auxiliary installer module 1012 is a ejection mechanism located inside the housing 1011. The analyte detection device 102 is located at the ejection end of the auxiliary installer module 1012. During use, the auxiliary installer module 1012 can quickly install the analyte detection device 102 onto the surface of the host's skin. The protective cover 103 is located at the front end of the auxiliary installer 101 and is releasably connected to the housing 1011. The protective cover 103 and the housing 1011 enclose an opaque internal space in which the analyte detection device 102 is located. When using the auxiliary installer 101, the user needs to first remove the protective cover 103 from the housing 1011 to expose the analyte detection device 102 to ambient light.
[0050] Figure 2 This is a schematic diagram of the analyte detection device according to an embodiment of the present invention. The analyte detection device 102 includes a housing 1021, a sensor 1022, a transmitter 1023, an internal circuit 1024, a battery 1025, and a wake-up module 1026. The sensor 1022 includes an external part 10221 and an internal part 10222. The external part 10221, the transmitter 1023, the internal circuit 1024, the battery 1025, and the wake-up module 1026 are all located inside the housing 1021. The internal part 10222 passes through a through hole 10211 on the housing 1021 to the outside of the housing, so as to be inserted into the subcutaneous tissue of the host to detect analyte parameter information. As those skilled in the art will know, in order to insert the internal part 10222 into the subcutaneous tissue of the host, the through hole 10211 is located on the side of the housing 1021 away from the housing 1011. At the same time, an adhesive tape (not shown in the figure) is also provided on this side for attaching and fixing the analyte detection device 102 to the surface of the host skin. The external part 10221 is electrically connected to the transmitter 1023 via the internal circuit 1024, and can transmit analyte parameter information to external devices.
[0051] Before use, the outer shell 1021 of the analyte detection device 102 and the outer shell 1011 of the auxiliary installer 101 can be releasably connected. Here, "releasable connection" means that the outer shell 1021 and the outer shell 1011 are connected together by means of buckles, clamps, etc. Under the action of the ejection mechanism of the auxiliary installation module 1012, the outer shell 1021 can be separated from the outer shell 1011.
[0052] When the sensor 1022 reaches the end of its service life, or the battery 1025 is depleted, or other factors cause the analyte detection device to fail, the user should remove the entire analyte detection device from the host's skin surface, discard it completely, and replace it with a new analyte detection device. This helps maintain the optimal condition of each component and improves the reliability of the analyte detection device.
[0053] When the analyte detection device 102 is installed on the host's skin surface and put into use, it needs to establish communication with external devices such as PDM (Personal Diabetes Manager) and mobile phones to exchange data and transmit the detected analyte information data in the host to the external devices.
[0054] As mentioned above, before the analyte detection device 102 formally establishes communication with external devices, it is in a sleep state and transmits signals to external devices at a first frequency. In this embodiment of the invention, the analyte detection device 102 transmits signals to external devices at a lower first frequency in the sleep state to reduce battery power consumption. In a preferred embodiment of the invention, the first frequency is 0 to 12 times / hour. In a more preferred embodiment of the invention, the first frequency is 0 times / hour, that is, the analyte detection device 102 does not transmit signals to external devices in the sleep state.
[0055] To enable the analyte detection device 102 in its dormant state to establish communication with external devices, the wake-up module 1026 wakes up the analyte detection device 102 according to trigger conditions, putting it into working mode. It then transmits signals to the external devices at a second frequency, establishing communication after the external devices respond. To facilitate convenient and real-time acquisition of analyte parameter information by the user, the second frequency is higher than the first frequency. In a preferred embodiment of the present invention, the second frequency is 12–3600 times / hour. In a more preferred embodiment of the present invention, the second frequency is 30 times / hour.
[0056] Example 1
[0057] Photosensitive element
[0058] Figure 3a This is a schematic diagram of the structure of the wake-up module of the analyte detection device according to an embodiment of the present invention, including a photosensitive element; Figure 3b This is a functional schematic diagram of the wake-up module of the analyte detection device according to an embodiment of the present invention, including a photosensitive element; Figure 3c This is a schematic diagram of the structure of the wake-up module of the analyte detection device according to another embodiment of the present invention, which includes a photosensitive element.
[0059] In this embodiment of the invention, the wake-up module 1026 includes a photosensitive element 10261, such as a photoelectric switch. When there is no light beam or a weak light beam, the photosensitive element 10261 is in an open circuit state, and when there is a light beam, the photosensitive element 10261 is in a closed circuit state.
[0060] Reference Figure 3a The transmitter 1023 is connected to the battery 1025 through the internal circuit 1024 to form a closed loop. A wake-up module 1026 is connected to the circuit. A photosensitive element 10261 is connected inside the wake-up module 1026. The trigger condition for the wake-up module 1026 is the change in light intensity received by the photosensitive element 10261.
[0061] In a preferred embodiment of the present invention, the trigger condition for the wake-up module 1026 is that the intensity of the light received by the photosensitive element 10261 changes from weak to strong.
[0062] In this embodiment of the invention, before the analyte detection device 102 is installed on the surface of the host skin, the analyte detection device 102 is not separated from the auxiliary installer 101. The outer shell 1021 and the housing 1011 form a sealed, opaque space. Since the light-transmitting area 10211 of the outer shell 1021 is located at one end close to the housing 1011, no external light shines on the photosensitive element 10261 at this time. The battery 1025 supplies power to the transmitter 1023 through the wake-up module 1026 (including the photosensitive element 10261). The photosensitive element 10261 is in an open circuit state, the transmitter 1023 is in a sleep state, and the analyte detection device 102 transmits a signal to an external device at a first frequency. After the analyte detection device 102 is installed on the surface of the host skin via the auxiliary installation module 1012, the outer shell 1021 is separated from the housing 1011. External light shines through the outer shell 1021 onto the photosensitive element 10261, which is in a closed-circuit state. The transmitter 1023 enters the working state, and the analyte detection device 102 transmits a signal to the external device at a second frequency. After the external device responds, communication is established, and analyte detection data is transmitted to the external device.
[0063] In this embodiment of the invention, the outer shell 1021 is made of a light-transmitting material, such as one of polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC) or poly4-methyl-1-pentene (TPX). The light transmittance of the above materials is 40% to 95%. After the outer shell 1021 is separated from the housing 1011, external light can pass through the outer shell 1021 to irradiate the photosensitive element 10261.
[0064] In other embodiments of the present invention, the housing 1021 includes a light-transmitting area 10211, the light transmittance of the light-transmitting area 10211 being higher than that of the housing 1021, so that more external light can irradiate the photosensitive element 10261, increasing the light intensity variation of the photosensitive element 10261 and improving the reliability of the photosensitive element 10261.
[0065] In another embodiment of the present invention, the light-transmitting area 10211 includes at least one light-transmitting hole, or an array of multiple light-transmitting holes. The light-transmitting hole allows more external light to illuminate the photosensitive element 10261, further increasing the light intensity variation of the photosensitive element 10261 and improving its reliability. In a preferred embodiment of the present invention, a light-transmitting film (not shown in the figure) is provided in the light-transmitting hole to prevent external water droplets, dust, and other contaminants from entering the analyte detection device through the light-transmitting hole, thereby improving the device's reliability.
[0066] In this embodiment of the invention, the photosensitive element 10261 can sense visible light or invisible light, such as infrared or ultraviolet light. In a preferred embodiment of the invention, the photosensitive element 10261 senses visible light, so that the user can activate the analyte detection device indoors or outdoors.
[0067] In another embodiment of the present invention, the open-circuit / closed-circuit switching condition of the photosensitive element is the transition from weak light irradiation to strong light irradiation. That is, before the outer shell 1021 is separated from the housing 1011, weak external light is allowed to irradiate the inside of the housing 1011. The photosensitive element 10261 receives the weak light but remains in an open-circuit state, and the transmitter 1023 is in a dormant state. This is because the actual connection between the outer shell 1021 and the housing 1011 is not completely sealed. After the outer shell 1021 is separated from the housing 1011, external light shines on the photosensitive element 10261 through the outer shell 1021 or the light-transmitting area 10211. The intensity of the light received by the photosensitive element 10261 increases. After reaching the set light intensity threshold, the photosensitive element 10261 switches to a closed-circuit state, and the transmitter 1023 enters the working state, transmitting a signal to the external device at a second frequency. After the external device responds, communication is established, and analyte detection data is transmitted to the external device.
[0068] Combined with reference Figure 1b and Figure 3c In another embodiment of the present invention, a protective cover 103 is further provided at the front end of the auxiliary installer 101. The protective cover 103 and the housing 1011 of the auxiliary installer 101 are in a releasable connection state. When the two are connected together, the housing 1011 and the protective cover 103 form a sealed, light-proof, enclosed cavity. When the user uses the auxiliary installer 101, the protective cover 103 needs to be removed. At this time, external light shines on the analyte detection device 102.
[0069] In this embodiment of the invention, the outer casing 1021 of the analyte detection device 102 includes an upper casing 10211 and a lower casing 10212. Adhesive tape 1027 is provided on the outer side of the lower casing 10212 for fixing the analyte detection device 102 to the user's skin surface. The external portion 10221 of the sensor 1022, the transmitter 1023, the internal circuitry 1024, the battery 1025, and the wake-up module 1026 are all located within the casing 1021.
[0070] In this embodiment of the invention, external light passes sequentially through the adhesive tape 1027 and the lower outer shell 10212 into the interior of the outer shell 1021, and illuminates the wake-up module 1026, activating the wake-up module 1026, thereby switching the analyte detection device 102 from a dormant state to a working state. To ensure sufficient external light can enter the outer shell 1021, both the adhesive tape 1027 and the lower outer shell 10212 are made of light-transmitting materials. For example, the adhesive tape 1027 is made of PU (polyurethane) film, PE (polyethylene) film, etc., and the lower outer shell 10212 is made of PMMA (polymethyl methacrylate), PS (polystyrene), PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), etc.
[0071] In this embodiment of the invention, to allow more external light to enter the interior of the outer casing 1021 and improve the response reliability of the wake-up module, a light-transmitting area (not shown in the figure) is also provided on the adhesive tape 1027 and the lower outer casing 10212. This light-transmitting area has a higher light transmittance than the adhesive tape 1027 and the lower outer casing 10212. For example, no adhesive material is applied to the light-transmitting area of the adhesive tape 1027, or glass or plastic with higher light transmittance is embedded in the light-transmitting area of the lower outer casing 10212. Any solution that can increase light transmittance can be applied to this embodiment of the invention, and no limitation is made here.
[0072] In other embodiments of the present invention, after the protective cover 103 is opened, the wake-up module 1026 is activated. After the analyte detection device 102 is ejected and installed, ambient light enters the device from the upper outer shell 10211, and the wake-up module 1026 is redundantly activated again, which can improve the working reliability of the wake-up module 1026. In this embodiment of the present invention, both the upper outer shell 10211 and the lower outer shell 10212 are made of light-transmitting material.

[0074] Magnetic components and magnetic sensing elements
[0075] Figure 4a This is a schematic diagram of the structure of the energy-saving analytical substance detection system according to an embodiment of the present invention, including magnetic components and magnetic sensing elements. Figure 4b This is a schematic diagram of the structure of the wake-up module of the analyte detection device according to an embodiment of the present invention, which includes a magnetic sensing element. Figure 4cThis is a functional schematic diagram of the wake-up module of the analyte detection device according to an embodiment of the present invention, including a magnetic sensing element.
[0076] In this embodiment of the invention, a magnetic element 203 is disposed on the housing 2011, and a magnetic sensing element 20261 is disposed within the wake-up module 2026. The magnetic element 203 provides a stable magnetic field, and the magnetic sensing element 20261 is located within the magnetic field of the magnetic element 203 and senses the magnetic field of the magnetic element 203 to generate a signal. The trigger condition for the wake-up module 2026 is the change in the magnetic field sensed by the magnetic sensing element 20261.
[0077] The transmitter 2023 is connected to the battery 2025 via an internal circuit 2024, forming a closed loop. A wake-up module 2026 is connected to the circuit, and the battery 2025 supplies power to the transmitter 2023 through the wake-up module 2026 (including the magnetic sensing element 20261). Before the analyte detection device 202 is installed on the host's skin surface, the analyte detection device 202 is not separated from the auxiliary installer 201, and its relative position is fixed. The magnetic sensing element 20261 senses that the magnetic field of the magnetic component 203 is stable. Under a stable magnetic field, the magnetic sensing element 20261 is in an open-circuit state, the transmitter 2023 is in a dormant state, and the analyte detection device 202 transmits signals to external devices at a first frequency. After the analyte detection device 202 is installed on the surface of the host skin via the auxiliary installation module 2012, the outer shell 2021 separates from the housing 2011, the distance between the magnetic sensing element 20261 and the magnetic component 203 changes, and therefore the sensed magnetic field also changes. The magnetic sensing element 20261 switches to a closed-circuit state, the transmitter 2023 enters the working state, and the analyte detection device 202 transmits a signal to the external device at a second frequency. After the external device responds, communication is established, and analyte detection data is transmitted to the external device.
[0078] In this embodiment of the invention, the magnetic sensing element 20261 senses the magnetic field strength or direction of the magnetic element 203. Preferably, the magnetic sensing element 20261 includes a Hall element (not shown in the figure), which can sensitively sense changes in the magnetic field strength of the magnetic element 203.
[0079] In this embodiment of the invention, the magnetic component 203 may be an individual part independent of the housing 2011, or it may be a part of the housing 2011 and embedded in the housing 2011.
[0080] In other embodiments of the present invention, the housing 2011 is embedded within or enclosed with a magnetic field shielding device (not shown in the figure), such as a Faraday cage. Those skilled in the art will understand that the magnetic field shielding device is located outside the magnetic component 203 to reduce the influence of external magnetic fields on the magnetic sensing element 20261.

[0083] Figure 5a This is a schematic diagram of the structure of the wake-up module of the energy-saving analytical substance detection system according to an embodiment of the present invention, which includes an acceleration sensor. Figure 5b This is a schematic diagram of the structure of the wake-up module of the analyte detection device according to an embodiment of the present invention, which includes an acceleration sensor. Figure 5c This is a functional diagram of the wake-up module of the analyte detection device according to an embodiment of the present invention, which includes an acceleration sensor.
[0084] In this embodiment of the invention, the wake-up module 3026 includes an accelerometer 30261, which can sensitively sense motion parameter values such as acceleration and adjust the circuit state of the wake-up module 3026 accordingly. The trigger condition for the wake-up module 3026 is a change in the motion parameters of the accelerometer 30261.
[0085] The transmitter 3023 is connected to the battery 3025 via an internal circuit 3024, forming a closed loop. A wake-up module 3026 is connected to the circuit, and the battery 3025 supplies power to the transmitter 3023 through the wake-up module 3026 (including an accelerometer 30261). Before the analyte detection device 302 is installed on the host's skin surface, the analyte detection device 302 and the auxiliary installer 301 are kept relatively fixed. In order to insert the internal part 30222 of the analyte detection device sensor into the host's subcutaneous tissue and reduce the pain during insertion, the auxiliary installer 3012 uses an ejection mechanism 30121, such as a spring or other elastic element, which allows the internal part 30222 to be quickly inserted into the host's subcutaneous tissue via the auxiliary needle 30122. When in use, the ejection mechanism 30121 generates a large instantaneous positive acceleration a1. After being installed on the surface of the host's skin, it generates a reverse acceleration a2 due to the obstruction of the skin. After the acceleration sensor 30261 senses the above two accelerations, it can determine that the analyte detection device 302 has been installed on the surface of the host's skin.
[0086] In this embodiment of the invention, before the analyte detection device 302 is installed on the host skin surface, the wake-up module 3026 is in an open-circuit state, and the transmitter 3023 is in a dormant state. The analyte detection device 302 transmits signals to external devices at a first frequency. After the accelerometer sensor 30261 determines that the analyte detection device 302 has been installed on the host skin surface, the wake-up module 3026 switches to a closed-circuit state, the transmitter 3023 enters a working state, and the analyte detection device 302 transmits signals to external devices at a second frequency. After the external device responds, communication is established, and analyte detection data is transmitted to the external device.
[0087] In summary, this invention discloses an energy-saving analyte detection system. The analyte detection device is in a dormant state before use. When the user uses it, the protective cover of the auxiliary installer is opened, and external light enters the housing of the analyte detection device through the tape and the outer shell, activating the wake-up module and putting the analyte detection device into working state. This can reduce battery energy consumption and extend the service life of the analyte detection device.
