Abstract

The invention discloses a gas pressure cell damage instrument which comprises a hyperbaric chamber, namely a stainless steel square box body. A circular box door is arranged on one side of the hyperbaric chamber; one side edge of the box door is hinged to the hyperbaric chamber; one or multiple lock catches for fastening is or are also arranged between the box door and the chamber body; an air valve is arranged on the box body and is connected with a compressor for pressurizing the hyperbaric chamber; a pressure gauge with a pressure sensitive device is also arranged on the hyperbaric chamber and is used for displaying pressure in the box body in real time; a bracket is arranged on the top surface of the box body of the hyperbaric chamber; a microscopic camera is mounted on the bracket; an observing window is corresponds to the microscope camera. The gas pressure cell damage instrument disclosed by the invention has the advantages of continuous observation, proper interference performed according to a cell damage condition and the like.

Description

technical field [0001] The invention relates to the field of medical detection instruments, in particular to a gas pressure cell damage instrument. Background technique [0002] A major mechanism of injury to the central nervous system, especially the spinal cord, is compression injury. In the in vitro experiment, the test cells are placed in a closed container, and compressed air is introduced to increase the internal pressure of the container, so that the cells are exposed to a high pressure environment, causing lateral compression on the cell membrane, causing damage to the integrity of the cell membrane, and simulating the central nervous system. Nervous system trauma established in vitro cell compression injury model. [0003] However, the existing pressure injury instrument can only record and observe the instantaneous cell damage state according to different pressure setting values. Observe the morphological changes of the experimental cell damage. Contents of the...
