A split-type respiratory oxygen consumption real-time monitoring device

Abstract

The invention relates to a split-type real-time monitoring device for respiratory oxygen consumption, which comprises a split type monitoring body, the split-type monitoring body comprises a base anda monitoring plate arranged in a monitoring area of a split-type monitoring body, and the base comprises a horizontally-laid base and a light-transmitting water storage plate arranged on the surface of the base; the upper surface of the water storage plate is provided with a water storage guide groove and a water storage groove located in a first end of the base. A power interface, a breathing signal interface, an oxygen consumption interface and an air inlet are formed in the outer side surface of the base; a snake-shaped oxygen consumption monitoring groove is carved in the inner surface, facing the monitoring area, of a monitoring plate; the photoresistors are evenly laid on a shading plate in the length direction of the snake-shaped oxygen consumption monitoring groove and connected with a biological signal collecting and processing system through a resistance detection circuit, and the biological signal collecting and processing system outputs animal oxygen consumption data according to data of a sampling resistor. The device has the beneficial effects that the oxygen consumption rate in any time period in the oxygen deficit process can be collected, and the harm of limit oxygen consumption to animals is avoided; and the experimental precision is high.

Description

technical field [0001] The invention relates to a split type breathing oxygen consumption real-time monitoring device. Background technique [0002] Hypoxia is a very common pathological process in various clinical diseases. Hypoxia in vital organs such as the brain and heart is an important cause of death, and it is also a problem that must be studied in plateau life, mine tunnel operations, and aerospace flight. In the experiments of medical colleges and universities, various hypoxia experimental models are often replicated to simulate hypoxia, and the pathological processes that lead to abnormal changes in tissue metabolism, function and morphological structure are studied through simulated hypoxia experimental models, in order to Explain the pathological process of various clinical diseases, explore their effective treatment methods, etc. [0003] At present, in the hypoxia experiments of medical colleges and universities across the country, the hypoxia measuring device...

Problems solved by technology

[0004] Among the new hypoxic devices above: the "respiratory oxygen consumption real-time monitoring device" can achieve normal pressure and constant pressure in a closed environment and realize real-time dynamic and automatic tracing of oxygen consumption and respiratory curves, but its existing defects are: The water tank and the monitoring tank are integrated and connected by channels. After a long time of storage, the water in the water storage tank will form water vapor and atomize into the monitoring tank to form water mist or form water droplets to adhere to the upper wall of the monitoring tank, occupying the monitoring tank. volume, which affects the accuracy of oxygen consumption measurement (the measured value of oxygen consumption is larger than the real value), and the blocking of light by water mist also affects the irradiation intensity of the photoresistor, which changes the sensitivity of the measuring device

If it is used repeatedly in a short period of time, a small amount of liquid will remain in the corner or right angle of the monitoring tank and cannot be discharged cleanly, which will affect the accurate measurement of oxygen consumption
