Novel oxygen-generating type respirator

Abstract

The invention discloses a novel oxygen-generating type respirator. The novel oxygen-generating type respirator comprises a mask, wherein a tee joint is arranged opposite to the mask, and the tee jointis connected with an exhalation valve through an exhalation pipeline; the exhalation valve is connected with an exhalation air bag through a pipeline, and the exhalation air bag is connected with a fan through a pipeline; the other end of the fan is divided into two branches, one of the branches is connected with a sensor, the other end of the sensor is connected with a displayer, the other branch is connected with an oxygen-generating medicine tank, and the other end of the oxygen-generating medicine tank is connected with a radiator, a heat dissipation plate and a particle filter in series;and the other end of the particle filter is connected with an air suction air bag, the other end of the air suction air bag is connected with an air suction valve, and the air suction valve is connected with the other end of the tee joint through an air suction hose. The novel oxygen-generating type respirator has the advantages that the structure is simple, the function is safe, the preparationand use are easy, oxygen cylinders and other auxiliary facilities are not needed, and the respirator is suitable for railways and the like; and compared with a respirator with compressed gas as an oxygen supply source, the respirator is free of needs of a gas filling pump and ice making equipment, maintenance is not needed at ordinary times, and therefore the respirator is particularly suitable for an urgent and quick response.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a novel oxygen-generating respirator. Background technique [0002] The respirator is a self-contained open-air respirator, widely used in firefighting, chemical industry, shipbuilding, petroleum, smelting, warehouses, laboratories, mines and other departments, for firefighters or emergency rescue personnel It can safely and effectively carry out fire extinguishing, emergency rescue and rescue work in various environments such as oxygen and oxygen. This series of products is equipped with a full-face mask with a wide field of view, bright and good airtightness, and the air supply device is equipped with a new type of air supply valve with small size, light weight and stable performance; high-strength backboard and high-quality high-pressure with high safety factor are selected. Gas cylinder; the pressure reducing valve device is equipped with a residual gas alarm, within the sp...

Problems solved by technology

[0003] At present, the respirators used in various industries in China are compressed oxygen respirators or compressed air respirators. These two respirators use the compressed gas in the cylinder as the oxygen supply source. Gas cylinders make the volume and quality of the respirator too large, and both respirators require regular maintenance and maintenance. For some non-professional users, it is troublesome to use
