Problems solved by technology

The disadvantages of this device are: the air extractor is heavy, and it is difficult to carry when preparing for the experiment; the air extractor has no switch, and the air extractor is driven by the switch on the switchboard, and the air pressure is difficult to reach the set value; the pipeline is long, there are many joints, and it is easy to age The air pressure is easy to leak; when the air pressure is not well controlled when deflated, the mercury in the glass tube will drop suddenly, which will easily cause the mercury to leak out and cause serious laboratory mercury pollution, which is also a major laboratory safety hazard

Abstract

The invention discloses an integrated hypoxia experiment simulation device and a method of mammals. The integrated hypoxia experiment simulation device comprises a processor module; the processor module is connected with a display module, a setting module, a sensor module, a power module and a control module; the control module is connected with a vacuum pump. The integrated hypoxia experiment simulation device provided by the invention has the characteristics of being compact in structure and convenient to use; besides; the device can automatically control vacuum pressure, reduce the operating difficulty of students making experiments, and enable the students to mainly focus on the observation of the hypoxia phenomenon, so that the experiment efficiency is greatly enhanced, and the experiment effect is improved; moreover, the experimental device is stable in experiment effect, high in repeatability and good in effect of experiment teaching.

Description

technical field [0001] The invention relates to the field of medical experiments, in particular to an integrated mammalian hypoxia experiment simulation device and method. Background technique [0002] Hypoxia can cause changes in respiratory function and lung morphology, as well as other system dysfunction, and even lead to death. In addition, age and changes in the functional state of the nervous system, changes in the external environment temperature, and CO 2 Increased concentration can affect the body's tolerance to hypoxia. [0003] The experiment of "Observation of Pathogenic Effects of Low Air Pressure in Mice" is to understand the characteristics of different types of hypoxia and various factors in hypoxia by observing the changes in respiratory function, lung shape, viscera and blood color of animals under various types of hypoxia. importance in disease. [0004] This experiment is not only a classic experiment in the pathophysiology experiment course, but also ...
