Positive-pressure breathing device for diving experiment of Bama miniature pig

Abstract

The invention discloses a positive-pressure breathing device for a diving experiment of a Bama miniature pig. The breathing device comprises a special diving gas cylinder and a gas transmission device; the gas transmission device comprises a primary regulator and a secondary regulator; the primary regulator is mounted at the upstream end of a gas conveying pipe; the secondary regulator is mountedat the downstream end of the gas conveying pipe; the primary regulator comprises a first regulating valve and a pressure gauge; the first regulating valve of the primary regulator is connected and fixed with a pressure reducing valve at the mouth of the special diving gas cylinder; the secondary regulator is provided with a second regulating valve; the second regulating valve is connected with a cylindrical respirator through a connecting pipe; the cylindrical respirator comprises a shell and an attaching mask arranged in the cavity of the shell, the opening end of the attaching mask extends out of the shell, a mask tightening belt is arranged at the opening end of the attaching mask, the shell is fixedly connected with an animal necklace through a connecting belt, and a breathing air outlet is formed in the second regulating valve.

Description

technical field [0001] The invention belongs to the technical field of diving equipment, and in particular relates to a positive-pressure breathing device for diving experiments of Bama Xiaoxiang pigs. Background technique [0002] With the rapid development of our army's border and coastal defense and the construction of islands and reefs, the threats to the security of border and coastal defenses and islands and reefs are becoming more and more serious, and the task of defending important areas is becoming more and more difficult. The Vietnamese navy has a large number of water special forces that are good at combat. The huge potential threat requires our army to improve its anti-frogman combat capabilities to improve the defense capabilities of naval bases and islands and reefs in the South China Sea. Establishing a scientific and practical animal model of frogman simulation experiment is the basis for carrying out anti-frogman military medical research. The existing exp...

Problems solved by technology

Due to the lack of underwater rebreathers for experimental animals, the model cannot fully simulate the frogman's underwater state.

However, the diving respirator currently used is only designed according to the physiological structure of human beings and cannot be applied to animals.
