Oxyhemoglobin saturation measuring equipment, method and device

Abstract

The invention discloses oxyhemoglobin saturation measuring equipment, method and device. The oxyhemoglobin saturation measuring equipment comprises a shell, protective glass, a light emitting unit, aprime lens, a focusing lens, an image sensor and a control unit, wherein an accommodating space is formed in the shell, a first light transmission hole communicating with the accommodating space is formed in the shell, and the protective glass is arranged in the first light transmission hole; the light-emitting unit is arranged in the accommodating space and is provided with a second light transmission hole; the prime lens, the focusing lens and the image sensor are arranged in the accommodating space and are sequentially arranged on a light propagation path; the control unit is electrically connected with the light-emitting unit and the image sensor; and the light-emitting unit alternately emits blue light and green light. The measuring equipment collects human tissue surface microcirculation videos under the irradiation of blue light and green light, and the oxyhemoglobin saturation value can be calculated through the human tissue surface microcirculation videos under the irradiationof the blue light and the green light.

Description

technical field [0001] The application belongs to the field of medical testing, and in particular relates to blood oxygen saturation measuring equipment, measuring methods and measuring devices. Background technique [0002] Blood oxygen saturation is one of the important physiological parameters of respiratory and circulatory function, reflecting the content of oxyhemoglobin in the blood, specifically defined as the capacity of oxyhemoglobin (HbO2) accounting for the total capacity of hemoglobin (Hb) that can be combined percentage. Blood oxygen saturation reflects the blood oxygen balance state of the human body. Monitoring blood oxygen saturation can estimate the oxygenation of the lungs and the oxygen-carrying capacity of hemoglobin, thereby monitoring the physiological conditions of human organs and tissues. [0003] The traditional blood oxygen saturation measurement method adopts the electrochemical method and the pulse oximetry detection method. In the process of re...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present application is to provide blood oxygen saturation measurement equipment, measurement methods and measurement devices, which can solve the problem of using electrochemical methods to measure blood oxygen saturation, which is easy to cause harm to patients, troublesome to operate, and cannot be continuously monitored. Pulse blood oxygen saturation detection method, if the fingertip is shifted during the measurement process, the patient's fingertip skin is cold or the color is abnormal, etc., it will affect the blood oxygen saturation monitoring, resulting in inaccurate data
