Description

Technical Field

[0001] The utility model relates to the technical field of medical products, in particular to a fetal heart rate monitor device capable of detecting fetal heart rate and blood oxygen. Background Art

[0002] The ultrasonic Doppler fetal heart rate monitor (hereinafter referred to as fetal heart rate monitor) products currently on the market are mainly used to listen to the fetal heart rate after 9 weeks of pregnancy for fetal screening. If you want to obtain the mother's physiological parameters at the same time during use, such as the mother's pulse rate, blood oxygen saturation, etc., you need to configure a blood oxygen probe separately. The detection is more troublesome to use. The test methods for blood oxygen are reflective detection and transmission detection.

[0003] In order to detect the mother's blood oxygen while detecting the fetal heart rate, fetal heart monitors on the market use reflective detection to add the blood oxygen detection function. A light hole is opened on the body of the device, and a light tube is set in the light hole. The signal is reflected by blocking the light hole with a finger. The light needs to pass through the skin and tissue layer, and then reflect back. The blood oxygen data is obtained based on the received signal. Although it can solve the problem of not needing an external blood oxygen probe, the signal intensity may be weakened due to tissue absorption and scattering during the measurement process, thereby affecting the accuracy of the measurement. In addition, the finger can only face the light tube. A slight deviation of the user's finger will cause differences in the results, resulting in low measurement efficiency, affecting the user's measurement experience, and not conducive to improving the competitiveness of the product.
