Vacuum pressure control method for low-pressure cabin

Abstract

The invention provides a vacuum pressure control method for a low-pressure cabin, and the low-pressure cabin comprises a cabin body, wherein the interior of the cabin body is a cabin room. The specific control method comprises the steps: increasing the vacuum pressure of the cabin room at a constant speed to a preset pressure value, wherein the preset pressure value is a pressure value corresponding to the altitude of 1400-1500 m; maintaining the preset pressure value of the cabin room for 40-45 minutes; and finally returning the vacuum pressure of the cabin room to the normal pressure. The method can meet the requirements of the safety and comfort of a user, enables the physiological index of the user not to change severely, and cannot cause the excessive discomfort of ears. According tothe invention, the structure can achieve the timely and accurate control, and provides guarantee for the actual operation steps.

Description

technical field [0001] The invention relates to a vacuum pressure control method of a low pressure chamber. Background technique [0002] The hypobaric chamber is a device that can form a hypobaric and hypoxic environment. It relies on the pumping device to create a hypobaric and hypoxic state in the chamber, and can adjust the air pressure in the chamber as needed to simulate a high-altitude environment. Oxygen endurance; especially for mountaineering enthusiasts and soldiers, allowing them to experience high-altitude environments at low altitudes. [0003] At present, with the improvement of science and technology and the change of research direction, researchers have found that the hypobaric chamber can not only simulate the high-altitude environment, but also has many benefits to the human body, such as improving the oxygen transport function of vascular tissue and improving cardiopulmonary function. Wait. [0004] Because the current low pressure chamber is not widely...

AI Technical Summary

Problems solved by technology

[0004] Because the current low pressure cabin is not widely used, its structural features are often designed to deal with professionals and soldiers, and the structural design of the cabin cannot meet the needs of ordinary people.
