Real-time monitoring device for respiration oxygen consumption equipped with upper water drainage structure

Abstract

Provided is a real-time monitoring device for respiration oxygen consumption equipped with an upper water drainage structure. A body is internally engraved with a capacity groove, an oxygen consumption monitoring groove, an air inlet guide groove and water drainage guide grooves. The upper surface of the body is equipped with an air inlet and an air outlet. The air inlet communicates with the capacity groove through an air inlet guide groove. One end of the oxygen consumption monitoring groove communicates with the capacity groove and the other thereof communicates with the air outlet. The joint for the capacity groove and the oxygen consumption monitoring groove is equipped with a protrusion. The groove bottom of the oxygen consumption monitoring groove is uniformly equipped with multiplephotoresistors. The photoresistors are orderly connected in series to form a sampling resistor and connected with a biology signal acquiring and processing system through a resistor detection circuit. The oxygen consumption monitoring groove has a zigzag shape. Air outlets of the water drainage guide grooves communicate with the capacity groove and the air inlet guide groove through a water return guide groove. The oxygen consumption monitoring groove communicates with air inlets of the water drainage guide grooves through an anti-backflow diversion device. Gaps are formed between water drainage depressions and diversion blocks and communicate with the oxygen consumption monitoring groove and the water drainage guide grooves.

Description

technical field [0001] The invention relates to a real-time monitoring device for respiratory oxygen consumption with an upper drainage structure. Background technique [0002] Hypoxia is an important pathogenic factor or one of the important pathological processes in the pathogenesis of various diseases in the body, and it is also a problem that must be studied in plateau life, mine tunnel operations and aerospace flight. Various hypoxia experimental models are commonly used to simulate hypoxia in the experiments of medical colleges and universities, and the simulated hypoxia experimental models are used to conduct physiological, biochemical, pharmacological, pathophysiological and clinical research in order to explain various clinical diseases Pathological process, explore its effective treatment methods, etc. [0003] At present, in the "National Medical Experiment Planning Textbook for Colleges and Universities", the classic device for hypoxia experiments on non-anesthe...

Problems solved by technology

Mice are used as experimental objects, because of their small size and fast breathing rate (200 times / min to 300 times / min), they often turn their positions during the hypoxia process, and it is impossible to accurately count the mouse's breathing rate by visual method , resulting in the experimental results often contradicting the expected results, affecting the experimental results and teaching quality

[0004] In addition, in the above-mentioned conventional oxygen consumption device, the oxygen consumption of the mice breathing causes the water in the graduated cylinder to move to the fat belly straw, causing the pressure in the hypoxic bottle to drop, that is, the mice are hypoxic in a negative pressure environment, so that the oxygen consumption Systematic errors in measurement results

[0005] In recent years, although there are mouse respiratory transducer amplifier products, the use of biological signal acquisition and processing systems and ordinary pressure transducers to measure mouse respiratory frequency in a closed environment, mouse normal pressure acute hypoxia model devices, and mouse oxygen consumption dynamics There have been reports on change measurement devices, but there have been no reports on quantitative analysis devices that can achieve normal pressure and constant pressure and realize real-time dynamic automatic tracing of oxygen consumption and respiratory curves in a closed environment
