Low-pressure oxygen cabin for experimental animals

Abstract

The invention provides a low-pressure oxygen cabin for experimental animals. The low-pressure oxygen cabin is characterized in that a water dispenser is communicated with environment air flow in the cabin. The low-pressure oxygen cabin has the advantages that the structure is simple, the operation is convenient, and the experimental animal soaking caused by water overflowing of the water dispenser can be avoided.

Description

technical field [0001] The invention relates to the field of medical and pharmacological basic research, in particular to a low pressure oxygen chamber for small experimental animals. Background technique [0002] In the field of medicine at home and abroad, the hypobaric oxygen chamber is the main means to prepare models of pulmonary hypertension and high altitude hypoxic disease, and is widely used in the research of the basis of altitude sickness and the prevention and treatment of drugs. The hypobaric oxygen chamber uses mechanical decompression to achieve an atmospheric pressure environment above 5,000 meters above sea level. During the decompression process, the water in the ordinary drinking bottle overflows as the pressure in the chamber decreases, so that the animals are soaked in a humid environment for a long time. The experiment The environment is poor and the animals are prone to dehydration, thus affecting the reliability of the experimental results. In order ...
