Description

Technical Field

[0001] This invention relates to the field of passive tag technology, and in particular to a subcutaneous implantable physiological parameter monitoring system for animals. Background Technology

[0002] In the livestock and poultry farming sector, animal body temperature is a core indicator reflecting their health status. Real-time and accurate monitoring of animal body temperature and other information is of great significance for disease prevention and control and health management. Currently, passive glass tube tags used for animal monitoring are all based on RFID technology, and can be divided into three categories according to different frequency bands: HF (high frequency), LF (low frequency), and UHF (ultra-high frequency). However, these tags have significant technical bottlenecks: HF band RFID tags typically have a reading range of less than 5cm, LF band tags less than 20cm, and while UHF band tags offer some improvement, they are still limited to less than 1m. This makes long-distance batch monitoring impossible, requiring close-range operation by staff, which is inefficient and easily disturbs animals. Furthermore, the power supply for radio frequency (RF) data is susceptible to environmental influences, especially during the dynamic movement of livestock, leading to unstable readings. In addition, existing passive RFID tags rely on the reader's RF power supply, which is limited. Powering the temperature sensor built into the RFID chip further reduces the tag's reading range, affecting normal use. Summary of the Invention

[0021] Figure 1 This is a schematic diagram of the structure of an animal subcutaneous implantable physiological parameter monitoring system provided in an embodiment of the present invention, as shown below. Figure 1As shown, the animal subcutaneous implanted physiological parameter monitoring system provided in this application is suitable for scenarios in large-scale farms where non-contact, long-distance, and batch physiological parameter monitoring of a large number of animals is required. It is used to periodically acquire deep subcutaneous physiological parameters of animals, providing data support for early warning of diseases, health status assessment, and precision feeding management. The animal subcutaneous implantable physiological parameter monitoring system includes: an infrared light source 10, a passive glass tube tag 20, and an information terminal 30; the passive glass tube tag 20 includes a glass tube encapsulation body 21, an infrared photosensitive module 22, a communication module 23, and a detection module 24; the glass tube encapsulation body 21 is used for implantation under the animal's skin; the glass tube encapsulation body 21 has a hollow structure, and the infrared photosensitive module 22, the communication module 23, and the detection module 24 are all located inside the glass tube encapsulation body 21; the infrared light source 10 is used to emit infrared light to the infrared photosensitive module 22 to provide working power and / or wake-up signals to the passive glass tube tag 20; the detection module 24 is used to collect physiological parameter information from under the animal's skin; the communication module 23 is used to transmit the physiological parameter information and the identity information of the passive glass tube tag 20 to the information terminal 30.

[0022] Specifically, during operation, an external infrared light source 10 emits infrared light to the passive glass tube tag 20 implanted under the animal's skin. The infrared photosensitive module 22 inside the glass tube encapsulation 21 receives the infrared light and converts it into electrical energy, providing power for the entire tag. After the tag is activated, the detection module 24 collects physiological parameter information (such as body temperature) from under the animal's skin. The communication module 23 transmits the collected physiological parameter information and the tag's own identification information to the information terminal 30 within the farm via wireless radio frequency signals. The information terminal 30 receives and parses the data, displays, and stores the physiological parameters of each animal.

[0023] This invention provides a subcutaneous implantable physiological parameter monitoring system for animals. An infrared photosensitive module converts received infrared light energy into electrical energy, driving the detection and communication modules. The detection module collects physiological parameters such as body temperature deep within the subcutaneous tissue; the communication module packages the collected data with tag identification information and wirelessly transmits it to an information terminal, enabling batch monitoring of animal physiological parameters over medium to long distances, meeting the health monitoring needs of large-scale livestock and poultry farming. Using infrared light as the wireless energy transmission carrier eliminates the need for internal battery replacement, allowing for long-term implantation under the animal's skin. This avoids the pain points of frequent animal capture and battery replacement required in large-scale farming, as with traditional wired monitoring or battery-powered tags. Compared to general passive RFID tags, this system overcomes the reading distance limitations of existing RFID tags, achieving medium-range batch detection and optimizing the detection process.

[0024] Among them, infrared light source 10 can be understood as a light source device that emits infrared light of a specific wavelength, such as an infrared LED or an infrared laser diode; glass tube encapsulation 21 can be understood as a biocompatible glass tube, such as borosilicate glass or quartz glass; infrared photosensitive module 22 can be understood as a device that converts infrared light energy into electrical energy; communication module 23 can be understood as a wireless communication unit such as a radio frequency transmitter, Bluetooth module, or active RFID; detection module 24 can be understood as a physiological parameter sensor integrated in the glass tube, such as a temperature sensor; and information terminal 30 can be understood as a remote data processing device with wireless receiving function.

[0025] Figure 2 This is a schematic diagram of the structure of an infrared photosensitive module provided in an embodiment of the present invention, for reference. Figure 2 In an optional embodiment, the infrared photosensitive module 22 includes a photosensitive unit 221, an energy storage unit 222, and a power management unit 223; the energy storage unit 222 is used to store the electrical energy generated by the photosensitive unit 221 and to supply power to the communication module 23 and the detection module 24; the power management unit 223 is electrically connected to the energy storage unit 222 and the photosensitive unit 221 respectively, and is used to control the energy storage unit 222 to supply power to the communication module 23 and the detection module 24 after detecting that the energy storage unit 222 is fully charged.

[0026] Specifically, when the external infrared light source 10 emits infrared light to illuminate the photosensitive unit 221, the photosensitive unit 221 generates electrical energy, which is then used by the power management unit 223 to charge the energy storage unit 222 and store the electrical energy. The power management unit 223 monitors the voltage across the energy storage unit 222 in real time. After detecting that the energy storage unit 222 is fully charged, it controls the energy storage unit 222 to supply power to the communication module 23 and the detection module 24, enabling these two modules to enter the working state.

[0027] In one specific embodiment, the infrared light source 10 is an infrared lamp array with a power of 50W, deployed at a distance of 1.5m from the pig. After the light source is turned on, the light intensity measured on the pig skin surface is approximately 1000μW / cm². 2 The light intensity measured at 15 mm subcutaneously (i.e., the tag implantation depth) was approximately 400 μW / cm. 2 Passive glass tube label 20, at 400 μW / cm 2Under appropriate illumination, the output voltage of the photosensitive unit 221 is 0.6V, and the output power is approximately 6μW, which meets the input requirements of the power management unit 223. The initial charging time of the energy storage unit 222 is 30 seconds, charging from 0V to 3V. After reaching 3V, the tag begins to operate (the detection module 24 collects physiological parameters, and the communication module 23 uploads data). Power supply ceases when the voltage reaches 1.8V, and the detection module 24 and communication module 23 enter sleep mode. Subsequently, the energy storage unit 222 charges from 1.8V to 3V in only 8 seconds for the second time. Therefore, as long as the infrared light source is present, the tag can maintain a "charging-operation-sleep-charging" cycle, achieving continuous and periodic monitoring and uploading of physiological parameters.

[0028] Optionally, the energy storage unit 222 is a multilayer ceramic capacitor or an organic thin film capacitor.

[0029] Specifically, multilayer ceramic capacitors have advantages such as small size, low equivalent series resistance, and fast charging and power supply speed, making them suitable for achieving high energy density and fast response under conditions where tag size is limited (the diameter of the glass tube package 21 is typically only 3mm-4mm). Organic thin film capacitors, on the other hand, have the characteristics of extremely low leakage current, low self-power, and good long-term stability, making them suitable for applications where the interval between two infrared light irradiations is long, thus preserving stored energy as much as possible and reducing energy loss. One of the above capacitor types can be flexibly selected as the energy storage unit 222 according to specific application requirements. Regardless of the capacitor selected, its withstand voltage should be higher than 3V, and the capacitance value needs to be optimized according to the tag power consumption and charging / power supply sequence. The energy storage unit 222, power management unit 223, and gallium arsenide photosensitive unit 221 work together to achieve 400μW / cm² energy at a depth of 15mm under the skin. 2 Under light intensity conditions, it achieves startup performance of charging from 0V to 3V within 30 seconds, and rapid recharging capability of recovering from 1.8V to 3V within 8 seconds in subsequent cycles.

[0030] Optionally, the photosensitive unit 221 includes one of gallium arsenide flexible hollow cylindrical photosensitive rod, gallium arsenide solid cylindrical photosensitive rod, and photodiode, and the structure of the photosensitive unit is cylindrical, with a diameter of 2.8mm-3.2mm and a length of 8mm-12mm.

[0031] Specifically, gallium arsenide (GaAs) materials possess characteristics such as a direct bandgap, high light absorption coefficient, and high carrier mobility. Their photoelectric conversion efficiency in the infrared band (e.g., 850nm-980nm) is significantly higher than that of silicon-based devices, making them particularly suitable for energy harvesting in low-light environments deep under the skin. Flexible hollow cylindrical photosensitive rods can reduce the overall weight of the tag and improve its vibration resistance; solid cylindrical photosensitive rods can maximize the light-receiving area and output power; photodiodes offer faster response speeds and lower dark currents. Regardless of the form chosen, its dimensions must match the internal dimensions of the glass tube package 21: a diameter of 2.8mm-3.2mm ensures that the photosensitive unit can be smoothly installed inside the glass tube without jamming; a length of 8mm-12mm provides sufficient remaining space for the energy storage unit 222, power management unit 223, communication module 23, and detection module 24.

[0032] It should be noted that the cylindrical glass tube encapsulation 21 has a smooth surface without sharp edges, which reduces tissue cutting and friction when implanted subcutaneously in animals, lowering the risk of inflammatory reactions and foreign body rejection, and is beneficial for long-term biocompatibility. Furthermore, the cylindrical hollow structure provides uniform mechanical stress distribution when subjected to subcutaneous tissue pressure (such as compression during animal activity or lying down), making it more pressure-resistant and less prone to breakage compared to other structures. Finally, the regular contact interface between the cylindrical outer surface and the subcutaneous tissue facilitates the uniform incidence of infrared light onto the glass tube surface after penetrating the tissue from an external light source, reducing light scattering and energy loss caused by irregular shapes. Therefore, to achieve a close fit with the cylindrical glass tube encapsulation 21, the photosensitive unit 221 is also designed as a cylinder, and its dimensions must match the inner cavity dimensions of the glass tube encapsulation 21 to ensure that the photosensitive unit can be smoothly installed inside the tube and that its sides are as close as possible to the inner wall of the glass tube, reducing the additional attenuation of infrared light transmission due to air gaps, thereby improving light coupling efficiency and ensuring that the tag can obtain sufficient electrical energy to maintain normal operation in the low-light environment deep under the skin.

[0033] Optionally, it also includes a detection station, which is a defined area for animals to stay or pass through; the infrared light source 10 is an infrared lamp array, and the infrared lamp array is set towards the detection station so as to illuminate the passive glass tube tag 20 implanted under the skin of the animal when the animal is in the detection station.

[0034] Specifically, the subcutaneous implantable physiological parameter monitoring system for animals also includes a detection station, which is a designated area for animals to stay or pass through, such as a restraint bar, automatic feeding station, or drinking station in a farm passageway. When an animal enters the detection station (e.g., while feeding in a restraint bar or passing through a passageway), an infrared lamp array emits infrared light under the animal's skin; the infrared photosensitive module 22 within the passive glass tube tag 20 implanted under the animal's skin receives the light energy and converts it into electrical energy, activating the tag to collect and upload physiological parameters. The information terminal 30 simultaneously receives the data uploaded by the tag via wireless signal. By setting up detection stations, non-contact, automated batch monitoring of a large number of animals can be achieved: animals only need to pass through or stay normally to complete the collection of physiological parameters, eliminating the need for manual capture or fixation, greatly reducing labor costs, and making it suitable for daily inspections and early disease warnings in large-scale farms.

[0035] Optionally, a handheld detection device is also included, which is equipped with an infrared light source 10.

[0036] Specifically, in large-scale farms, in addition to automated batch monitoring at fixed testing stations, when an abnormal alarm occurs or sampling testing is required, operators can bring a handheld testing device close to the animal, aim the device at the location of the subcutaneous implanted tag, activate the infrared light source 10 to emit infrared light, and stimulate the subcutaneous passive glass tube tag 20 to work.

[0037] Optionally, the detection module 24 is a body temperature detection module; physiological parameter information includes body temperature information.

[0038] Specifically, detection module 24 is a body temperature detection module; physiological parameter information includes body temperature information. In the passive glass tube tag 20 implanted subcutaneously in the animal, the body temperature detection module is thermally coupled through the glass tube encapsulation body 21. Because deep subcutaneous body temperature is more stable and better reflects the animal's true health status compared to surface temperature, the information terminal 30, after receiving the body temperature information reported by each tag, can perform trend analysis and anomaly alarms by combining the animal's ID number and timestamp, assisting farmers in timely isolating sick animals and reducing the risk of epidemic transmission.

[0039] Optionally, the embedding depth of the passive glass tube label 20 is 10-20mm.

[0040] Specifically, when the implantation depth is less than 10mm, the tag is too close to the skin surface, making it prone to displacement, exposure, or even detachment due to friction from animal activity or external impact. Additionally, the superficial subcutaneous tissue has a rich blood supply, increasing the risk of inflammatory reactions. When the implantation depth is greater than 20mm, the scattering and absorption of infrared light as it passes through the skin and subcutaneous tissue significantly increase, resulting in excessive light intensity attenuation (e.g., the light intensity measured at 15mm subcutaneously is approximately 400μW / cm²). 2 If buried deeper, the power may drop to 200 μW / cm.2 The following may result in insufficient output power of the photosensitive unit 221 to support the normal operation of the tag.

[0041] Optionally, the outer wall of the glass tube package 21 is coated with an infrared anti-reflection film to increase infrared light transmittance.

[0042] Specifically, since the passive glass tube tag 20 is embedded 10-20mm deep under the animal's skin, the infrared light is significantly attenuated after passing through the skin tissue. Using an infrared anti-reflection film can effectively improve light energy utilization efficiency, allowing the photosensitive unit 221 to obtain higher incident light intensity under the same external light source conditions. This increases the photoelectric conversion output power, shortens the charging time of the energy storage unit 222, or allows the tag to maintain normal operation at greater embedding depths or lower light source power.

[0043] Optionally, the glass tube encapsulation body 21 is a cylindrical hollow structure, and both ends are sealed with medical-grade silicone or glass firing process.

[0044] Specifically, the glass tube encapsulation body 21 is a cylindrical hollow structure. The smooth surface of the cylindrical glass tube encapsulation body 21, without sharp edges, reduces tissue cutting and friction when implanted subcutaneously in animals, lowering the risk of inflammatory reactions and foreign body rejection, and promoting long-term biocompatibility. Furthermore, the cylindrical hollow structure provides a uniform distribution of mechanical stress when subjected to subcutaneous tissue pressure (such as compression during animal activity or lying down), making it more pressure-resistant and less prone to breakage compared to other structures. Finally, the regular contact interface between the cylindrical outer surface and the subcutaneous tissue facilitates the uniform incidence of infrared light onto the glass tube surface after penetration from the external light source, reducing light scattering and energy loss caused by irregular shapes. Medical-grade silicone has good biocompatibility, resistance to body fluid corrosion, and long-term stability. Its elasticity can absorb some mechanical impact, reducing the risk of glass tube breakage due to animal activity or external forces. Compared to rigid sealing (such as glass firing processes), silicone sealing is simpler, lower in cost, and avoids thermal damage to internal electronic components caused by high-temperature melting. When using the glass firing process for sealing, the two ends of the glass tube are melted and sealed at high temperature to form an integrated sealing structure of the same material as the tube body. This has higher sealing airtightness and mechanical strength, and is suitable for scenarios that require long-term implantation and have extremely high requirements for waterproofing and moisture resistance. The two sealing methods can be flexibly selected according to specific application needs.
