Embodiment Construction

[0040] In the prior art, there is no non-underwater test method and equipment for various types of diving respirators, and there is no corresponding breathing power simulation device and oxygen consumption device suitable for testing diving respirators. device, and there is no better testing method for breathing resistance.

[0041] For this reason, the present invention provides a kind of underwater breathing simulation device and underwater breathing simulation method thereof, described underwater breathing simulation device divides the breathing process of human body into two main processes, one is inhalation and exhalation The other is the oxygen consumption process. Correspondingly, the present invention makes the underwater breathing simulation device include a gas pumping device for pumping gas, so as to realize the simulation of human inhalation and exhalation, and make the underwater breathing simulation The device includes an oxygen consumption device to realize the ...

Abstract

The invention discloses an oxygen consumption device and a use method thereof. The oxygen consumption device comprises a plurality of oxygen consumption pipes and a plurality of vent pipes, a gas input end of each oxygen consumption pipe is provided with a one-way valve, a gas output end of each oxygen consumption pipe is provided with an oxygen monitoring device, liquid oxygen consumption agents or solid oxygen consumption agents are arranged in the oxygen consumption pipes, a gas input end of each vent pipe is provided with a one-way valve, and the volume of breathing gas passing one oxygen consumption pipe is equal to that of breathing gas passing one vent pipe within same time. The oxygen consumption device is simple in composition structure, the opening and closing states of different one-way valves can be simply controlled, and oxygen consumption proportion can be quantitatively controlled in the corresponding breathing gases, so that the simulation process of oxygen consumption is simplified.

Description

technical field [0001] The invention relates to the field of diving equipment, in particular to an oxygen consumption device and a using method thereof. Background technique [0002] The traditional diving respirator consists of an oxygen cylinder, a primary pressure reducing valve, a secondary pressure reducing valve and a mouthpiece, commonly known as "scuba". Diving rebreathers can be divided into different types such as open rebreathers, semi-closed rebreathers and closed rebreathers. [0003] The breathing resistance of the diving rebreather is one of the main reasons for the diver's load to increase during the dive. Generally, divers rely on changing breathing intensity and mode underwater to adapt to changes in breathing resistance to ensure breathing flow. Breathing resistance is also an important evaluation index for evaluating diving respirators. Diving respirator is a personal underwater breathing protection device, and it is of great significance to detect its...
