Embodiment Construction

[0009] An implementation structure of the present invention will be further described in conjunction with the accompanying drawings. The original structure of the earmuffs includes figure 1 The earmuff shell 1, the earmuff cavity 2, and the earmuff cushion 3 in the earmuff, the earmuff cushion 3 is closely attached to the skin around the auricle when worn normally. The realization structure of the pulse wave detection circuit of the present invention includes figure 1 The dual-wavelength photoelectric sensor 4, the signal conditioning circuit 5, the data acquisition and control circuit 6, the data transmission circuit 7, and the power supply circuit 8, 5, 6, 7, and 8 are in the earmuff cavity 2, and 4 are in the earmuff soft Pad 3 surface. The realization process of pulse wave detection is: the dual-wavelength photoelectric sensor 4 installed on the surface of the earmuff soft cushion 3 converts the received two optical signals containing the blood flow information of the hu...

Abstract

The invention relates to a method for realizing photoelectric pulse wave detection by using earmuffs. The method for adding a photoelectric pulse wave detecting function on the earmuffs is provided to people who need normal operation and cannot conveniently wear sensors on the hands. The operation of a user is not affected during detection. Circuits used for detecting pulse waves are additionally arranged on the earmuffs; double-wavelength photoelectric sensors are arranged on surfaces of soft cushions contacted with a human body; and a part of other circuits is arranged in cavities of the earmuffs. When people wear the earmuffs to normally work, two routes of photoelectric pulse waves can be detected through the sensors contacted with the human tissues around auriculas and the detecting circuits arranged in the cavities of the earmuffs, and the blood oxygen saturation parameter is calculated. Photoelectric pulse wave detection is performed by the earmuffs worn on an operator, and a new detection device is not added, so that the load of the operator is not increased, and the operation ability is not affected.

Description

technical field [0001] The invention relates to an earmuff photoelectric pulse wave detection method, which is a method for adding a physiological parameter detection function to the original structure of the earmuff. Background technique [0002] The human pulse wave signal contains rich physiological and pathological information of the cardiovascular system, which is a common detection parameter in clinical and scientific research. The pulse wave detection equipment based on the principle of photoelectric detection has the advantages of simple structure, non-invasive, and good repeatability. Photoelectric detection is divided into The transmission and reflection methods can detect many parts of the human body. At present, the fingertip transmission method is widely used. By using a dual-wavelength sensor, two photoelectric pulse waves can be obtained and blood oxygen saturation parameters can be calculated. However, for those who still need to work normally during the dete...
