Problems solved by technology

[0004] For the detection of ethyl nitrite concentration, there is Fourier infrared spectroscopy, but the sensitivity of infrared detection method is low. For the detection of ethyl nitrite with a concentration of ppm level, it is usually necessary to make a special detection cell by infrared spectroscopy to extend the optical path. , to detect

Embodiment Construction

[0017] The invention relates to a gas-blood exchange rate detection device for ethyl nitrite, which mainly includes a gas-blood exchange chamber and a gas chromatography-mass spectrometer.

[0018] Such as figure 1 As shown, the gas-blood exchange cavity is divided into two chambers by the gas-permeable membrane 3, one of which is the blood chamber 10, which is used to accommodate blood, and is provided with a blood inlet and a blood outlet, and the blood inlet is connected with a pipe. A blood bag 1 is provided for the blood cavity, and a valve F1 for controlling blood flow is arranged on the pipeline. The blood in the blood bag 1 may suffer from problems such as insufficient oxygen content, so blood exchange is needed to improve blood quality. The blood after the exchange of qi and blood flows out from the blood outlet, which is connected with a flexible pipe connected to the human vein, and is inserted into the human vein through the flexible pipe to provide blood transfus...

Abstract

The invention relates to a detection device of ethyl nitrite gas-blood exchange rate, which comprises a gas-blood exchange cavity and a gas-chromatography-mass-spectrometer, wherein the gas-blood exchange cavity is separated into two cavities by a ventilated membrane; the two cavities comprise a blood cavity to accommodate blood and a gas cavity to accommodate ethyl nitrite mixed gas; the ethyl nitrite mixed gas can penetrate through the ventilated membrane to enter the blood in the blood cavity to exchange air and blood; and the gas-chromatography-mass-spectrometer is used for analyzing the ethyl nitrite content of the ethyl nitrite mixed gas after the gas-blood exchange and the ethyl nitrite mixed gas before the exchange. The detection device can penetrate ethyl nitrite mixed gas into the blood through the ventilated membrane, improves the oxygen content of the blood through the gas-blood exchange, meanwhile detects the blood on-line by adopting the gas-chromatography-mass-spectrometer, and confirms the exchange rate of the ethyl nitrite.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically relates to a detection device for the gas-blood exchange rate of ethyl nitrite. 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. Its quality not only affects the oxygen supply of organs, but also affects the degree of damage of RBCs when they pass through capillaries, and affects the efficiency of blood transfusion. 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 ...
