Abstract
Description
Technical Field
[0001] This utility model relates to the field of wearable health monitoring equipment technology, and in particular to an ear loop body temperature monitor and a body temperature monitoring system having the same. Background Technology
[0002] Body temperature is one of the important physiological indicators for measuring human health. Real-time and accurate monitoring of body temperature is of vital importance in clinical diagnosis, postoperative monitoring and family health management.
[0003] Currently, the mainstream body temperature measurement tools on the market mainly include traditional mercury thermometers, handheld electronic thermometers, and some emerging wearable thermometers. While traditional mercury thermometers provide relatively accurate results, they suffer from drawbacks such as long measurement times, fragility, and the risk of mercury contamination, making them unsuitable for continuous monitoring. Handheld electronic thermometers (such as forehead thermometers and ear thermometers) offer rapid readings, but they are designed for intermittent, single measurements, requiring active user operation and thus unable to achieve unattended, automated, continuous monitoring.
[0004] To address the need for continuous monitoring, wearable temperature monitoring devices, such as patch thermometers, have emerged in this field. However, existing wearable thermometers still have some problems in practical applications. For example, measurement accuracy is easily affected by interference, especially patch thermometers based on the contact temperature measurement principle. Their measurement accuracy is highly susceptible to changes in external ambient temperature, wearer activity, or poor contact caused by sweating. These interference sources can lead to significant deviations in measurement readings and unstable data, thereby reducing the reliability of monitoring results. Furthermore, structural designs often prioritize ease of wear while neglecting the impact of the structure itself on measurement accuracy. For instance, the heat generated by the device itself is directly conducted to the temperature measurement area, fundamentally affecting the accuracy of the measurement. Utility Model Content

[0021] In the real-time reading mode, the display module is illuminated to display the current temperature value, and the wireless communication module transmits data as needed;
[0022] In the long-term monitoring mode, the display module remains off to save power, while the wireless communication module periodically sends the temperature value to an external device.
[0023] On the other hand, the body temperature monitoring system according to an embodiment of the present invention includes:
[0024] The ear-loop body temperature monitor as described above; and
[0025] A smart terminal is configured to wirelessly connect with the ear-loop body temperature monitor to receive the temperature value sent by it and analyze and display it on a display interface.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0059] The following describes in detail, with reference to the accompanying drawings, an ear loop type body temperature monitor 100 and a body temperature monitoring system having the same.
[0060] Reference Figures 1 to 7 As shown, the ear loop body temperature monitor 100 provided according to the embodiment of this utility model includes a main body 10, an infrared temperature sensing module 20, a microprocessor module 30, a display module 40, a wireless communication module 50, and a power supply module 60.
[0061] Specifically, the main body 10 is adapted to be worn on the user's ear. For example, the main body 10 can adopt an ergonomic C-shaped or ear-hook structure, and its material is preferably a medical-grade or skin-friendly polymer material, such as silicone, ABS resin, or polycarbonate, to ensure wearing comfort, biocompatibility, and reduce overall weight. The main body 10 has an internal mounting cavity for mounting modules such as the microprocessor module 30, the wireless communication module 50, and the power module 60.
[0062] A probe 101 protrudes from the main body 10, the size and shape of which are adapted for insertion into the user's ear canal. The probe 101 is integrally formed with the main body 10 or detachably connected. The geometry and shape of the probe 101 allow it to be safely and comfortably inserted into the user's external auditory canal. Specifically, the front end of the probe 101 may be designed with a smooth conical or elliptical contour to guide it smoothly into the ear canal without causing pressure or discomfort.
[0063] An infrared temperature sensing module 20 is disposed on the detection unit 101 for non-contact acquisition of temperature data within the ear canal. This infrared temperature sensing module 20 can be installed at the end or side wall of the detection unit 101, with its detection window facing deep into the ear canal to capture infrared radiation energy emitted by surrounding tissues in a non-contact manner.
[0064] A thermal isolation structure is provided between the detection unit 101 and the main body 10 to reduce the conduction of heat from the main body 10 to the detection unit 101. This thermal isolation structure reduces the heat generated by the electronic components operating inside the main body 10, transferring it to the detection unit 101 via solid-state conduction, thereby reducing interference from these heat sources with the infrared temperature sensing module 20. In one implementation, the thermal isolation structure can be achieved by using a material with low thermal conductivity, such as engineering plastics PEEK or polytetrafluoroethylene (PTFE), for the connecting neck 1011 between the main body 10 and the detection unit 101. In another embodiment, the thermal isolation structure can be a physical cavity or gap, for example, by designing a hollow, extremely thin-walled connecting arm, utilizing air as a poor heat conductor to achieve thermal isolation. More preferably, a composite structure combining a low thermal conductivity material with an internal air gap can be used to achieve better thermal isolation, ensuring that the infrared temperature sensing module 20 measures the true physiological thermal radiation from inside the ear canal.
[0065] A microprocessor module 30 is disposed inside the main body 10 and electrically connected to the infrared temperature sensing module 20, for processing the temperature data to obtain a temperature value. A display module 40 is disposed on the outer surface of the main body 10 and electrically connected to the microprocessor module 30, for displaying the temperature value in real time; exemplarily, the display module 40 is an OLED display screen. A wireless communication module 50 is disposed inside the main body 10 and electrically connected to the microprocessor module 30, for wirelessly transmitting the temperature value to an external device. A power supply module 60 is used to power the various modules of the monitor.
[0066] During operation, the infrared temperature sensing module 20 on the detection unit 101 continuously collects infrared radiation signals from inside the ear canal and transmits these analog signals to the microprocessor module 30 located inside the main body 10 via a flexible printed circuit board (FPC) or other electrical connection methods. After receiving the signal, the microprocessor module 30 performs signal amplification, analog-to-digital conversion, and other processing to finally calculate the user's body temperature value.
[0067] After calculating the real-time temperature value, the microprocessor module 30 can output the temperature value to the display module 40, presenting the temperature data digitally in real time for instant local monitoring. Simultaneously, the microprocessor module 30 transmits the temperature data to the wireless communication module 50 via an internal bus. The wireless communication module 50 periodically transmits the temperature value to an external device via wireless signals. This external device can be a smartphone, tablet, smartwatch, or a monitoring workstation in a hospital environment. This not only enables remote viewing of the data but also allows for long-term recording and trend analysis of body temperature data via an application, as well as triggering advanced alarm functions when body temperature is abnormal, thus forming a complete and automated body temperature monitoring system.
[0068] The ear-loop body temperature monitor 100 provided in this embodiment of the present invention achieves automated continuous monitoring by utilizing an ear-loop wearing method and wireless communication function. Furthermore, by employing an infrared temperature sensing module 20 to non-contactly detect the relatively enclosed and stable ear canal environment, compared to a patch thermometer, it significantly reduces measurement errors caused by poor contact due to wearer activity and sweating, as well as changes in external ambient temperature. In addition, by providing a thermal isolation structure between the main body 10 and the detection unit 101 where the infrared temperature sensing module 20 is located, the heat generated by the operation of electronic components within the main body 10 can be reduced from being conducted to the temperature measurement area, thereby improving the stability and data reliability of continuous body temperature monitoring.
[0069] In one embodiment of this utility model, the infrared temperature sensing module 20 is specifically used to simultaneously collect target temperature data in the ear canal and ambient temperature data of the detection unit 101.
[0070] The microprocessor module 30 is specifically used to perform compensation calculations based on the target temperature data and the ambient temperature data, using a preset temperature compensation method, to generate a compensated temperature value.
[0071] Specifically, the infrared temperature sensing module 20 integrates a sensing element (e.g., a thermopile) for detecting target infrared radiation, and one or more ambient temperature sensing elements (e.g., a thermistors) for measuring the sensor's own operating temperature. For example, the infrared temperature sensing module 20 can use an MLX90615 infrared temperature sensor. Therefore, the infrared temperature sensing module 20 can output two independent data points in a single acquisition. One is the target temperature data reflecting the intensity of infrared radiation from the surrounding tissue deep in the ear canal, and the other is the ambient temperature data reflecting the internal microenvironment temperature of the detection unit 101 at the current moment, i.e., the reference temperature of the infrared temperature sensing module 20 itself. These two data points are synchronously transmitted to the microprocessor module 30.
[0072] When the microprocessor module 30 receives the target temperature data and ambient temperature data from the infrared temperature sensing module 20, it uses these two data points as input variables and substitutes them into a preset temperature compensation formula for compensation calculation. This allows for real-time and dynamic reduction of drift and deviation in measurement results caused by fluctuations in the sensor's own temperature, ultimately calculating a more accurately compensated temperature value that better reflects the true physiological state. For example, the temperature compensation formula is as follows:
[0073] T comp =T obj_raw +S·(T obj_raw -T a )
[0074] Among them, T comp The final temperature value, T obj_raw For the target temperature data, T a The ambient temperature data represents the sensor's operating temperature. S is a preset compensation coefficient, calculated during factory production using calibration equipment and stored in each microprocessor module 30.
[0075] By adopting the above technical solution, this embodiment uses the infrared temperature sensing module 20 to simultaneously collect the target temperature data in the ear canal and the ambient temperature data of the detection unit 101. The microprocessor performs real-time calculations according to the preset compensation formula, thereby realizing temperature calibration and improving the accuracy of temperature measurement and stability during continuous long-term monitoring.
[0076] Reference Figure 2 As shown, in one embodiment of the present invention, the thermal isolation structure is a connecting neck 1011 with a reduced diameter cross-section integrally formed between the detection part 101 and the main body 10.
[0077] In this embodiment, the thermal insulation structure employs a simple implementation, with the cross-section of the connecting neck 1011 designed as a reduced-diameter section. According to Fourier's law, the rate of heat conduction in a solid is proportional to the cross-sectional area of the conduction path. By reducing the cross-sectional size of the connecting neck 1011, the rate of heat transfer is effectively curbed. Simultaneously, the connecting neck 1011 has a certain length, further increasing the path length for heat conduction, which, together with its reduced-diameter section, enhances the thermal insulation effect.
[0078] Reference Figure 4 As shown, in one embodiment of the present invention, the power module 60 includes a battery input terminal controlled by a switch SW1, a charging input terminal, and a three-terminal voltage regulator U11 for converting the input voltage into a stable operating voltage. Both the input and output terminals of the three-terminal voltage regulator U11 are connected in parallel with filter capacitors.
[0079] The power module 60 employs a three-terminal regulator U11 to ensure a stable operating voltage regardless of the battery's charge level. By configuring parallel filter capacitors at the input and output of the three-terminal regulator, the purity and dynamic stability of the power supply are improved. The input capacitor ensures the stable operation of the three-terminal regulator itself, while the output capacitor effectively suppresses high-frequency noise and handles instantaneous changes in load current. This enhances the overall anti-interference capability and reliability of the body temperature monitor.
[0080] Reference Figure 5 and Figure 7 As shown, in one embodiment of this utility model, the wireless communication module 50 is a Bluetooth module U2. The data transmitting end and data receiving end of the Bluetooth module U2 are connected to the serial communication interface of the microprocessor module 30. That is, the data transmitting end (TXD) of the Bluetooth module U2 is connected to the data receiving end (RXD) of the serial interface of the microprocessor module 30, and the data receiving end (RXD) of the Bluetooth module is connected to the data transmitting end (TXD) of the microprocessor module 30. Through this interface, the microprocessor packages the processed temperature data into a data frame of a predetermined format and serially sends it to the Bluetooth module U2 via its TXD pin, and then the Bluetooth module U2 performs wireless radio frequency transmission; conversely, control commands from external devices can also be received by the Bluetooth module U2 and transmitted to the microprocessor through this path.
[0081] The infrared temperature sensing module 20 is connected to the microprocessor module 30 via an I2C bus. Pull-up resistors R1 and R3 are connected to both the data and clock lines of the I2C bus. Since the I2C bus uses an open-drain output structure, the two pull-up resistors R1 and R3 can pull the signal lines to a high level in the default state when the bus is idle, providing a stable logic high level for the bus signals and ensuring communication reliability and anti-interference capabilities.
[0082] At least one decoupling capacitor, C2, and C3 are connected between the power input pin and ground of the microprocessor module 30 for power filtering. When the microprocessor module 30 operates at high speed, the rapid switching of its internal logic gates generates instantaneous high-frequency current spikes, causing disturbances to the power rails. The decoupling capacitors C2 and C3, typically small-value ceramic capacitors, provide rapid charge replenishment for these instantaneous current spikes due to their excellent high-frequency response characteristics, and filter out high-frequency noise on the power lines. This effectively maintains stable voltage at the microprocessor power pins, preventing logic errors, program crashes, or unexpected resets caused by power noise.
[0083] Reference Figure 1As shown, in some embodiments of this utility model, a control switch 102 is also included. The control switch 102 is connected to the interrupt input pin of the microprocessor module 30 and is used to control the on or off state of the display module 40.
[0084] This embodiment provides a highly efficient and user-friendly power management method by setting a control switch 102 connected to the microprocessor's interrupt pin. When the user does not need to view the readings, the display can be completely turned off, and the microprocessor can remain in a deep sleep state for extended periods, only being awakened when an interrupt event occurs, thus significantly extending the device's battery life on a single charge. Furthermore, users can instantly and conveniently wake the screen to view data, or actively turn off the screen for privacy in public places, making the device more interactive and user-friendly while fulfilling its core monitoring functions.
[0085] In one embodiment of the present invention, the control switch 102 is also used to control the microprocessor to switch between instantaneous reading mode and long-term monitoring mode.
[0086] In the instant reading mode, the display module 40 is illuminated to display the current temperature value, and the wireless communication module 50 transmits data as needed.
[0087] In the long-term monitoring mode, the display module 40 remains off to save power, while the wireless communication module 50 periodically sends the temperature value to an external device.
[0088] In practical use, users can trigger the switching of working modes by controlling switch 102. For example, pressing and holding switch 102 for 2 to 3 seconds will switch between the two modes, while a short press will temporarily turn the screen on or off in the current mode.
[0089] In real-time reading mode, the monitor prioritizes providing immediate and intuitive feedback. The microprocessor module 30 immediately powers on the display module 40 and collects and refreshes the currently measured temperature value at a high frequency, allowing the user to see the body temperature reading in real time. Simultaneously, the wireless communication module 50 sends data on demand in this mode. For example, the monitor only sends the current temperature data when a paired external device initiates a data request. In contrast, in long-term monitoring mode, the monitor aims to maximize battery life and achieve unattended long-term data recording. The microprocessor immediately sends a command to the display module 40 to keep it off or in sleep mode. In this mode, body temperature monitoring and data transmission run silently in the background. The wireless communication module 50 periodically sends data, for example, every 5 minutes, to external devices for recording and analysis. This mode is suitable for scenarios requiring long-term continuous recording of body temperature curves, such as postoperative monitoring and infant sleep temperature monitoring.
[0090] This embodiment realizes the mode switching function through the control switch 102, which greatly improves the application flexibility and intelligence level of the product, enabling it to adapt to different application scenarios and meet the needs of different scenarios.
[0091] Reference Figure 8 As shown in the figure, this utility model embodiment also provides a body temperature monitoring system, including an ear loop body temperature monitor 100 as described in the above embodiment and a smart terminal 200, wherein the smart terminal can be a smartphone or a tablet computer or other electronic device.
[0092] The smart terminal 200 is configured to wirelessly connect with the ear-loop body temperature monitor 100 to receive the temperature value transmitted by it and analyze and display it on a display interface (e.g., Figure 9 and Figure 10 (As shown).
[0093] According to the body temperature monitoring system provided in this embodiment, the ear-loop body temperature monitor 100 described above achieves automated continuous monitoring by utilizing the ear-loop wearing method and wireless communication function. Furthermore, by employing an infrared temperature sensing module 20 to non-contactly detect the relatively enclosed and stable ear canal environment, compared to a patch thermometer, it significantly reduces measurement errors caused by poor contact due to wearer activity and sweating, as well as changes in external ambient temperature. In addition, by providing a thermal isolation structure between the main body 10 and the detection unit 101 where the infrared temperature sensing module 20 is located, the heat generated by the operation of electronic components within the main body 10 can be reduced from being conducted to the temperature measurement area, thereby improving the stability and data reliability of continuous body temperature monitoring.
[0094] In one embodiment of this utility model, the smart terminal 200 is further configured to trigger an alarm when the received temperature value is lower than a first preset threshold or higher than a second preset threshold.
[0095] In practical applications, users can set one or more body temperature warning thresholds according to specific circumstances, such as a first preset threshold (e.g., 36.0℃) for indicating low body temperature and a second preset threshold (e.g., 37.5℃) for indicating fever.
[0096] After receiving temperature data, the temperature value is compared with the user's first preset threshold and second preset threshold. Once the temperature value is detected to be lower than the first preset threshold or higher than the second preset threshold, an alarm will be triggered, such as by emitting continuous or intermittent alarm sounds, vibration, or popping up a prominent warning window on the screen.
[0097] In one embodiment of this utility model, the smart terminal 200 is further configured to visualize the multiple temperature values received in a time sequence as a time-varying curve (e.g., Figure 10 (As shown). In this way, data visualization and analysis functions can be provided, enabling users to intuitively grasp the long-term trend of body temperature changes.
