Intermittent hypoxia experimental device for cells

Abstract

The invention discloses a cell intermittent hypoxia experiment device which comprises an upper sleeve and a lower supporting cylinder which are distributed in the direction from top to bottom, a clamping structure is arranged between the upper sleeve and the lower supporting cylinder, an air pressure detection structure and an air conditioning structure are arranged on the upper sleeve, and the air pressure detection structure is composed of an airtight column and an air diaphragm. The air conditioning structure is composed of a first connecting air nozzle and a connecting ring sleeve, a three-way air inlet part is arranged in the air conditioning structure, the clamping structure is composed of a connecting ring frame and a threaded ejector rod, the tail end of the connecting ring frame is installed on the circumferential outer wall of the lower supporting cylinder, and a threaded positioning block is fixedly installed at the center point of the connecting ring frame; and the threaded positioning block is in threaded connection with the threaded ejector rod. In the using process, the device can be suitable for various cell sample experiments, in the experiment process, the air content in the device can be accurately controlled, and the device is good in air tightness and easy to regulate and control.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to an experimental device for intermittent hypoxia of cells. Background technique [0002] The physiological function of various animals is related to cell activity, and cell activity refers to the physiological state and function of cells. For example, many factors such as temperature environment and oxygen-containing environment have an impact on cell activity. Among them, the oxygen-containing environment has the most prominent influence on it. [0003] Various experimental projects are carried out for cell activity, including the intermittent hypoxia experimental project. This experiment mainly studies the effect of different oxygen concentration environments on cell activity, and the cell viability of cell samples cultured in different oxygen concentration environments. different, so that different experimental parameters can be obtained. [0004] At present, mo...

Problems solved by technology

[0004] At present, most of the instruments used in the hypoxia experiment are temporary components. Various instruments are combined to match the progress of the experiment. After the experiment is over, they have to be disassembled again. The airtightness of the experimental device is not good, and there is also a single use. Each assembly process is only for one experimental cell, so it cannot be applied to a variety of cell samples. The application process is extremely inconvenient. Therefore, in order to solve this problem For this type of problem, we propose a cellular intermittent hypoxia experimental setup
