Lung-structure oxygen regulator for high-altitude parachuting

Abstract

The invention relates to a lung-structure oxygen regulator for high-altitude parachuting. The lung-structure oxygen regulator comprises a valve, an oxygen inlet joint, an oxygen flow regulating module, an air flow regulating module, a lung-structure oxygen supply module, a residual pressure guarantee module, a manual oxygen supply module and an oxygen supply outlet joint are integrated on the valve, the oxygen flow regulating module is arranged in an oxygen regulating chamber, the air flow regulating module is arranged in an air inlet, the lung-structure oxygen supply module and the residual pressure guarantee module are arranged at the connection between an oxygen outlet and an air chamber, and the manual oxygen supply module is arranged between the oxygen inlet and the air chamber. The lung-structure oxygen regulator can automatically and intermittently supply oxygen or air-oxygen mixture according to the breathing rhythm of a user, the fact that a certain safety residual pressure ismaintained at the whole altitude of a breathing mask, meanwhile, the oxygen supply flow and oxygen concentration are automatically adjusted according to the change of altitude, the breathing comfort,safety and oxygen utilization rate of the user are increased, the weight of oxygen supply equipment is reduced, and the oxygen demands of a parachutist at the altitude of 10000 meters and below are met.

Description

technical field [0001] The invention relates to an oxygen regulator, in particular to a lung type structure oxygen regulator used for skydiving. Background technique [0002] The oxygen regulator is a core component of the oxygen supply device used in the high-altitude skydiving process, which is used to supply sufficient oxygen or air and oxygen mixture to the skydivers to meet the high-altitude oxygen consumption physiological needs of the skydivers. An oxygen regulator with excellent performance can better improve the efficiency of oxygen use while reducing the weight and volume of the oxygen system. In the process of high-altitude skydiving, when the weight of the support device is getting lighter and smaller, the problem of oxygen supply is becoming more and more serious, which requires that the breathing of personnel can still be guaranteed under the condition of reducing the amount of oxygen carried. Physiological safety. In the existing high-altitude skydiving oxyg...

AI Technical Summary

Problems solved by technology

In the existing high-altitude skydiving oxygen supply, the shortcomings are: the oxygen supply equipment is heavy in weight, large in size, low in oxygen utilization efficiency, and needs to provide a large amount of excess oxygen for personnel to use
