Gas pressure control system of pressure cabin for medical security car capable of realizing highland pressurization

Abstract

The invention discloses a gas pressure control system of a pressure cabin for a medical security car capable of realizing highland pressurization, which comprises an automatic air inlet valve, an automatic CO2 exhaust valve, a CO2 sensitive element, an O2 sensitive element, a gas concentration display instrument, a gas pressure display instrument, automatic control equipment and a booster fan, wherein the automatic air inlet valve and the automatic CO2 exhaust valve are arranged on the inner wall of the pressure cabin; the CO2 sensitive element, the O2 sensitive element, the gas concentration display instrument, the gas pressure display instrument, the automatic control equipment and the booster fan are arranged on the inner wall of the pressure cabin; the CO2 sensitive element and the O2 sensitive element are connected with the gas concentration display instrument and the gas pressure display instrument through signals; the gas concentration display instrument, the gas pressure display instrument, the automatic air inlet valve and the automatic CO2 exhaust valve are respectively connected with the automatic control equipment through signals; and the booster fan is connected with the automatic air inlet valve through signals. According to the gas control system of the pressure cabin for the medical security car capable of realizing the highland pressurization, the defects in the prior art of poor reliability, poor safety, poor applicability, inconvenience for use and the like can be overcome, so that the advantages of high integrated level, good reliability, good safety, good applicability and convenience for use are realized.

Description

technical field [0001] The invention relates to a motor vehicle, in particular to a gas pressure control system of a pressurized cabin for a plateau pressurized medical security vehicle. Background technique [0002] As we all know, the plateau environment is characterized by low pressure, low oxygen, and dry and cold climate. As the altitude increases, the partial pressure of oxygen in the air continues to decrease. If people are in this hypoxic environment for a long time, severe cases may develop hypoxia. blood disease. Because the human nervous tissue is most sensitive to changes in the internal and external environment, under the condition of high altitude hypoxia, brain function damage occurs first, and the damage is more serious, and the longer the exposure time, the more serious the damage, especially for sensation, memory, thinking, The effects on cognitive functions such as vision and attention were significant and long-lasting. [0003] Setting up pressurized me...
