An electronic thermometer with self-checking and high-precision temperature measuring function

Abstract

The application discloses an electronic thermometer and infrared thermometer with self-checking and high-precision temperature measuring functions. The existing electronic thermometer and infrared thermometer often have large temperature measuring errors and cannot be self-checked due to aging of a single temperature sensor and other factors. Two or more temperature sensors are integrated on the thermometer, and multiple temperature values are measured at the same position. Through comparison and analysis, if the values are in a reasonable error interval and close to each other, the average value is calculated to obtain a more accurate temperature; if the error is out of the interval, an error is reported to indicate that the thermometer cannot be used continuously. The design can improve the temperature measuring precision, can self-check the health state of the components, can ensure that the measurement result is accurate and reliable, and has important application value in the field of medical temperature measurement.

Description

Technical Field

[0001] This invention belongs to the field of medical devices. It discloses an electronic thermometer and an infrared thermometer with self-testing and high-precision temperature measurement functions. This invention integrates two or more temperature sensors on the thermometer to measure multiple temperature values ​​at the same location. Through comparative analysis, if the values ​​are within a reasonable error range and close to each other, the average value is calculated to obtain a more accurate temperature. If the error exceeds the range, an error message is displayed indicating that the thermometer can no longer be used. This design not only improves temperature measurement accuracy but also self-tests the health status of components, ensuring accurate and reliable measurement results. It has significant application value in the field of medical temperature measurement. Background Technology

[0002] Electronic and infrared thermometers, as common medical measurement tools, play a vital role in body temperature monitoring. However, existing electronic and infrared thermometers have some significant problems in practical use. Currently, most electronic and infrared thermometers rely on a single temperature sensor to measure temperature. However, after prolonged use, temperature sensors may experience a gradual decrease in measurement accuracy due to aging, environmental factors, or other unknown reasons, resulting in significant errors. This error can lead to inaccurate temperature readings, potentially affecting the diagnosis and treatment of patients. Furthermore, because there is only a single temperature sensor, users often fail to notice malfunctions or excessive errors, and continued use of an inaccurate thermometer may result in misdiagnosis or delayed treatment. In addition, the results from a single temperature sensor inherently have limitations, failing to completely eliminate the influence of random factors, leading to inaccurate measurements. While some research and improvement efforts have been undertaken to address these issues, an ideal solution that effectively and conveniently resolves temperature sensor errors and self-testing problems has yet to be found. Summary of the Invention

[0003] To address the problems of large sensor errors and lack of self-testing capabilities in existing electronic and infrared thermometers, this invention incorporates a series of innovative improvements. First, this invention integrates two or more temperature sensors into a single thermometer. Multiple temperature sensors simultaneously measure temperature at the same location, obtaining multiple temperature values. These values ​​are then compared and analyzed. If all measurements are within a reasonable error range and are relatively close, it indicates that the thermometer's measurement results are accurate and reliable. The average of these values ​​can then be calculated to obtain a more precise temperature measurement. Conversely, if the error between the measurements exceeds the reasonable range, it indicates that at least one temperature sensor is malfunctioning. In this case, the thermometer can promptly issue an error message, informing the user that the thermometer should not be used further and requires repair or replacement. This multi-temperature sensor design and comparative analysis mechanism not only effectively solves the measurement error problem caused by the aging of a single temperature sensor or other factors but also enables the thermometer to perform self-testing, promptly detecting and alerting to potential faults, ensuring the accuracy and reliability of the measurement results.

[0005] The electronic thermometer and infrared thermometer of the present invention, featuring self-testing and high-precision temperature measurement functions, mainly consist of the following parts. The front end of the thermometer houses multiple temperature sensors, which are evenly distributed to ensure consistent temperature data is obtained from the same measurement site. The temperature sensors are connected to a processing chip via sophisticated circuitry. The processing chip receives and analyzes the temperature data from each sensor. Internally, the chip has a preset reasonable error range and judgment algorithm. Upon receiving multiple temperature values, the chip first compares these values. If all values ​​are within the error range and close to each other, the chip calculates their average and displays the final measurement result on the screen. If any temperature value exceeds the error range, the chip immediately activates an error reporting mechanism. Error reporting can be achieved through sound, light, or specific prompts on the display screen, alerting the user that the thermometer may be malfunctioning.

[0006] To ensure the stability and reliability of the thermometer, high-quality electronic components are used throughout the circuitry, and a rigorous anti-interference design is implemented. The thermometer's casing also features an ergonomic design for easy grip and operation. During production, each component undergoes strict quality testing, particularly the sensor and processing chip, to ensure their performance meets design requirements. Furthermore, after assembly, comprehensive performance testing and calibration are performed to guarantee the thermometer's measurement accuracy and the precision of its self-testing function.

[0007] The electronic thermometer and infrared thermometer of this invention, featuring self-testing and high-precision temperature measurement, have significant industrial applicability. In terms of production, although the number of sensors has increased and the chip algorithm has been modified, the hardware manufacturing cost has not increased significantly. Existing production technologies and equipment can meet its manufacturing requirements, enabling large-scale, high-efficiency production and effectively controlling overall production costs. In terms of the market, as people's attention to health continues to increase, the requirements for the accuracy and reliability of body temperature measurement are also growing. This self-testing and high-precision temperature measurement electronic thermometer meets the urgent market demand and has broad market prospects. In terms of application, it is not only suitable for accurate measurement of patient body temperature in medical institutions but also for daily body temperature monitoring in homes, providing strong support for the early detection and prevention of diseases. In terms of benefits, the high-precision measurement results help improve the accuracy of medical diagnosis, reduce the risk of misdiagnosis, and bring significant economic and social benefits to users and society.
