Gas and blood exchange blood oxygen saturation monitoring device

Abstract

The invention relates to a qi-blood exchange blood oxygen saturation monitoring device. The device comprises a qi-blood exchange chamber and a blood oxygen detection part; the qi-blood exchange chamber is divided into three cavities by two gas-permeable films, the three cavities comprise a blood cavity positioned in the middle and an ethyl nitrite mixed gas cavity and an oxygen cavity which are positioned at two sides of the blood cavity respectively, and an ethyl nitrite mixed gas in the ethyl nitrite mixed gas cavity and oxygen in the oxygen cavity respectively permeate the two gas-permeable films and enter blood in the blood cavity for qi-blood exchange; and the blood oxygen detection part is a photoelectric blood oxygen detector and is used for detecting the blood oxygen saturation of the blood after the qi-blood exchange. The qi-blood exchange is carried out by permeating the gas-permeable films through adopting the device in order to improve the oxygen content of the blood; whether the exchanged blood has a full oxygen content or not is detected through the blood oxygen detection part; and the adoption of the photoelectric blood oxygen detector enables the accuracy to be high and the blood oxygen detection accuracy to be improved.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically, to a gas-blood exchange blood oxygen saturation monitoring device. Background technique [0002] The deformability of red blood cells (also known as red blood cells, RBC for short) is one of the main factors to maintain the effective perfusion of microcirculation. mass, and these changes in RBC were associated with the absence of nitric oxide (NO). Quantitative supplementation of ethyl nitrite gas to the transfused blood can form nitrosothiol (RSNO) in the blood, thereby releasing NO, which can not only improve the quality of transfused blood, but also make the formed RSNO and the released NO play a role. Certain physiological effects. [0003] Ethyl nitrite is a congener of NO, and the covalent bond of ethyl nitrite is broken mainly in the form of heterocleavage to produce NO + , has many biological activities similar to NO, and is easy to produce RSNO through transnitrol...

AI Technical Summary

Problems solved by technology

At present, the detection methods of blood oxygen saturation mainly include optical detection and electrochemical detection. There are already complete equipment and instruments for sale in the market, but these instruments and equipment directly act on human tissues and perform non-invasive treatment on the blood inside the human body. The detection of blood oxygen saturation, when the blood oxygen saturation is detected inside the human body, is easily disturbed by personal physical conditions, such as the beating of the pulse, the absorption of light by other tissues, etc., making the measurement inaccurate
