Description

Technical Field

[0001] This invention relates primarily to the field of medical devices, and in particular to an analyte detection system. Background Technology

[0002] 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.

[0003] 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).

[0004] 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.

[0005] 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

[0006] This invention discloses an analyte detection system, including an auxiliary installer and an analyte detection device. Before use, the analyte detection device is in a dormant state, transmitting signals to external devices at a first frequency. When installed on the host's skin surface via the auxiliary installer, a wake-up module activates the analyte detection device according to trigger conditions, bringing it into operation. In operation, the analyte detection device transmits signals to external devices at a second frequency and establishes communication with them. The first frequency is lower than the second frequency, improving user experience while reducing battery consumption and ensuring the lifespan of the analyte detection device.

[0007] This invention discloses an analyte detection system, comprising: an auxiliary installer, which includes a housing and an auxiliary installation module located within the housing; and an analyte detection device, which includes a housing, a sensor, a transmitter, internal circuitry, a battery, and a wake-up module. The sensor includes an external portion and an internal portion, and the internal portion, transmitter, internal circuitry, battery, and wake-up module are located within the housing. Before use, the housing is releasably connected to the housing, and the analyte detection device is in a dormant state, transmitting signals to external devices at a first frequency. When the analyte detection device is installed on the host's skin surface via the auxiliary installation module, the wake-up module wakes up the analyte detection device according to trigger conditions, enabling it to enter a working state and transmit signals to external devices at a second frequency. After receiving a response from the external device, communication is established with the external device.

[0008] According to one aspect of the present invention, the wake-up module includes a photosensitive element. After the outer shell is separated from the housing, external light shines on the photosensitive element through the housing. The triggering condition is a change in the illumination of the photosensitive element.

[0009] According to one aspect of the invention, the housing includes a light-transmitting area through which ambient light shines onto the photosensitive element.

[0010] According to one aspect of the invention, the material of the outer shell or the light-transmitting area is one of polymethyl methacrylate, polystyrene, polycarbonate or poly4-methyl-1-pentene.

[0011] According to one aspect of the invention, the light transmittance of the outer casing or the light-transmitting area is 40% to 95%.

[0012] According to one aspect of the present invention, the light-transmitting area includes at least one light-transmitting hole, in which a light-transmitting film is disposed.

[0013] According to one aspect of the invention, a magnetic element is provided on the housing, and the wake-up module includes a magnetic sensing element.

[0014] According to one aspect of the present invention, a magnetic sensing element senses the magnetic field of a magnetic component, and the triggering condition is a change in the magnetic field of the magnetic sensing element.

[0015] According to one aspect of the invention, the wake-up module includes an accelerometer.

[0016] According to one aspect of the present invention, an accelerometer senses the motion state of an analyte detection device, and the triggering condition is a change in the motion parameters of the accelerometer.

[0017] According to one aspect of the invention, the first frequency is less than the second frequency.

[0018] 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.

[0019] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0020] In the analyte detection system disclosed in this invention, the analyte detection device is in a dormant state before use, transmitting signals to external devices at a lower first frequency. When installed on the host's skin surface by an auxiliary installer, the wake-up module wakes up the analyte detection device according to the trigger conditions and enters the working state. In the working state, the analyte detection device transmits signals to external devices at a higher second frequency and establishes communication with external devices, improving the user experience. At the same time, the dormant state can reduce battery energy consumption and ensure the service life of the analyte detection device.

[0021] Furthermore, the wake-up module includes a photosensitive element. When the analyte detection device housing is connected to the auxiliary installer housing, the photosensitive element is located within the sealed space of the auxiliary installer, where external light cannot or barely reaches the photosensitive element. When the analyte detection device is installed onto the host's skin surface via the auxiliary installer module, the housing separates from the main housing, and external light shines onto the photosensitive element through the light-transmitting area. The photosensitive element senses the change in light intensity, and the wake-up module wakes up the analyte detection device, putting it into working condition. This reduces battery energy consumption before use and allows for real-time communication with external devices during use, enhancing the user experience.

[0022] Furthermore, the material of the outer shell or the light-transmitting area is one of polymethyl methacrylate, polystyrene, polycarbonate or poly4-methyl-1-pentene, and the light transmittance of these materials is 40% to 95%, so that external light can shine onto the photosensitive element through the outer shell or the light-transmitting area.

[0023] Furthermore, the light-transmitting area includes at least one light-transmitting hole, in which a light-transmitting membrane is provided to prevent external water droplets, dust, and other contaminants from entering the device, thereby improving the reliability of the analyte detection device.

[0024] Furthermore, the wake-up module includes a magnetic sensing element, and a magnetic component is provided on the auxiliary installer housing. When the analyte detection device housing is connected to the auxiliary installer housing, the magnetic sensing element senses the magnetic field of the magnetic component. When the analyte detection device is installed on the host's skin surface through the auxiliary installer module, the housing separates from the housing, and the magnetic sensing element senses the change in the magnetic field of the magnetic component. The wake-up module then wakes up the analyte detection device, puts it into working state, and transmits signals to the outside world. This not only avoids wasting battery energy before use but also allows for real-time communication with external devices during use, enhancing the user experience.

[0025] Furthermore, the wake-up module includes an accelerometer. When the analyte detection device is installed onto the host's skin surface via the auxiliary installation module, the outer shell separates from the housing. The accelerometer senses the change in the motion state of the analyte detection device, and the wake-up module wakes up the analyte detection device, putting it into working mode and transmitting signals to the outside world. This avoids wasting battery energy before use and also allows for real-time communication with external devices during use, enhancing the user experience. Attached Figure Description

[0036] 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.

[0037] To address this problem, the present invention provides an analyte detection system, which includes a wake-up module. Before use, the analyte detection device is in a dormant state and transmits signals to external devices at a first frequency. When the analyte detection device is installed on the surface of the host's skin via an auxiliary installation module, the wake-up module wakes up the analyte detection device, putting it into working mode and transmitting signals to external devices at a second frequency, where the first frequency is lower than the second frequency.

[0038] 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 specifically stated otherwise, 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.

[0039] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not necessarily drawn to actual scale; for example, the thickness, width, length, or distance of some units may be enlarged relative to other structures.

[0040] The following description of exemplary embodiments is merely illustrative and is not intended to limit the invention or its application or use in any way. 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.

[0041] It should be noted that similar labels 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.

[0042] Figure 1This is a schematic diagram of the analyte detection system according to an embodiment of the present invention. The analyte detection system 10 includes an auxiliary installer 101 and an analyte detection device 102. The auxiliary installer 101 includes a housing 1011 and an auxiliary installation module 1012. In this embodiment, the auxiliary installation 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 installation module 1012. In use, the auxiliary installation module 1012 can quickly install the analyte detection device 102 onto the surface of the host skin.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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 more preferred embodiment of the invention, the first frequency is 0 to 12 times / hour. In an even 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.

[0048] 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.

[0049] Example 1

[0050] Photosensitive element

[0051] 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.

[0052] 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.

[0053] Combination Figure 1 and Figure 3b 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 is higher than that of the housing 1021, so that more external light can irradiate the photosensitive element 10261, thereby increasing the light intensity variation of the photosensitive element 10261 and improving the reliability of the photosensitive element 10261.

[0058] 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.

[0059] 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.

[0060] 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.

[0062] Magnetic components and magnetic sensing elements

[0063] Figure 4a This is a schematic diagram of the structure of the analytical substance detection system according to an embodiment of the present invention, including a magnetic component and a magnetic sensing element. 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 4c 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 magnetic sensing element.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0070] Accelerometer

[0071] Figure 5a This is a schematic diagram of the structure of the wake-up module of the analyte 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] In summary, this invention discloses an analyte detection system. Before use, the analyte detection device is in a dormant state and transmits signals to external devices at a first frequency. When installed on the host's skin surface by an auxiliary installer, the wake-up module wakes up the analyte detection device according to trigger conditions and enters the working state. In the working state, the analyte detection device transmits signals to external devices at a second frequency and establishes real-time communication with external devices, improving the user experience while reducing battery energy consumption and ensuring the service life of the analyte detection device.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
