Heart rate measuring method in ear canal based on hearing aid

Abstract

The invention discloses a heart rate measuring method in an ear canal based on a hearing aid. The method comprises an intelligent mobile phone, a digital hearing aid and an APP loaded on the mobile phone for calculating the heart rate. The digital hearing aid comprises a DSP module, an audio input module, an audio output module, a Bluetooth module and a photoelectric heart rate sensor. The photoelectric heart rate sensor is connected with the DSP module, the Bluetooth module is connected with the DSP module, and the audio input module and the audio output module are connected with the DSP module. In a measurement process, a photoelectric heart rate sensor on the digital hearing aid is arranged in an ear canal of a wearer. The heart rate of the wearer is monitored in real time through the photoelectric heart rate sensor, an analog electric signal is generated, the analog electric signal is transmitted to a DSP of the digital hearing aid, the DSP processes the analog signal and convertsthe analog signal into a digital signal, the digital signal is transmitted to an APP running on the intelligent mobile phone platform through the Bluetooth module, and the APP displays a pulse waveform and a heart rate value after receiving the digital signal.

Description

technical field [0001] The invention belongs to the technical field of electronic hearing aids, and in particular relates to a hearing aid-based method for measuring the heart rate of the auditory canal. Background technique [0002] With the improvement of people's living standard, people pay more and more attention to their health. In real life, there are often the following problems: traditional medical testing is expensive, the operation is cumbersome, the waiting time is long, and there is little time to go to the hospital. With the rapid development of smart product technology, smart watches, smart bracelets, high-performance medical and health care equipment and smart wearable products have appeared in front of people, and they have also solved many inconveniences in people's lives. For digital hearing aids, in the existing technology, it has also begun to consider implanting health-care functions, such as body temperature, pulse, etc. For smart products to detect he...

Problems solved by technology

In real life, there are often the following problems: traditional medical testing is expensive, the operation is cumbersome, the waiting time is long, and there is little time to go to the hospital

The disadvantage of electrode measurement is that it requires the user to measure consciously, but cannot automatically and continuously measure and upload data, let alone realize remote monitoring

The existing digital hearing aids measure heart rate using the earphone close to the ear canal to form a closed space. Due to the vibration of the eardrum, a certain pressure will be generated in the ear canal, and the pressure will change with the vibration. The microphone is used to collect the pressure in the ear canal. change information, so as to detect the heart rate, for the above technical solution, the heart rate measurement error rate is large, and the design is complicated

At the same time, in other existing technical solutions, some photoelectric pulse detection equipment mainly uses infrared light to measure blood, and its design is limited to a certain extent.
