Embodiment Construction

[0014] For a better understanding of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-2 As shown, a pressure simulation test device includes a preparation cabin 3, a test cabin 5, a cabin door 4, a gas pressurization device and an oxygen supply system 6, and a test interface 7 is provided on the test cabin. Through the test interface 7, the equipment tests the performance of the products in the cabin and monitors and tests the physiological parameters of the human body. The physiological parameters of the human body include blood pressure, heart rate, blood oxygen saturation, etc. There is a cabin at the connection between the preparation cabin 3 and the test cabin 5. Door 4. After closing the door, the test cabin is in a sealed state. There is a pool 8 in the test cabin. When personnel do not enter the pool, they can pressurize and depressurize the test cabin separ...

Abstract

The invention discloses a pressure simulating and testing device which comprises a testing cabin, wherein a pool is arranged inside the testing cabin; an air inlet and an exhaust hole are formed in the testing cabin; the air inlet is connected with an air pressurizing device through a pipeline; the exhaust hole is communicated with the atmosphere through a valve; the air pressurizing device is used for pressurizing and depressurizing the testing cabin; a water supply and discharge device is used for adjusting the water level of the pool; an oxygen supply device is used for inputting oxygen into the testing cabin; a testing platform is used for testing the property of a product inside the cabin through a testing interface in the testing cabin and used for monitoring and testing human body physiological parameters. The pressure simulating and testing device is capable of simulating an environment with the water depth of 20-30m, can meet the physical property testing and relevant physical testing on an underwater breather, and has a function of preventing decompression sickness in a hyperbaric oxygen chamber.

Description

technical field [0001] The invention relates to a pressure simulation test device, in particular to a system capable of performing underwater performance detection on life-saving devices such as underwater breathing apparatus. Background technique [0002] The underwater breathing apparatus can provide 1 to 3 minutes of underwater emergency oxygen supply to save life during emergency evacuation of the aircraft. Due to the difference in the depth of water entry, the physiological response of the human body under water is also different. How to adapt the air supply flow and air supply pressure of the underwater breathing apparatus to the physiological needs of the human body is the biggest difference between the development of the underwater breathing apparatus and other oxygen supply equipment. , is also one of the main technical characteristics of underwater breathing apparatus. In the process of product development, according to technical requirements, an environmental con...
