Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressurized cabin, in particular to a high-strength portable soft pressurized cabin optimization system. BACKGROUND

[0002] Pressurized treatment is a standard treatment method for decompression diseases, and portable pressurized cabins play an increasingly important role in the field rescue and transportation of wounded personnel due to their small size and strong portability.

[0003] Currently, portable pressurized cabins are limited by cabin materials and structures, and the general working pressure is about 0.02-0.1 MPa. Because the working pressure is low, the treatment effect is limited. In order to improve the pressure-bearing capacity of the portable soft pressurized cabin, some designs use metal fences or hard shells, which can increase the working pressure but also greatly increase the weight and reduce the portability.

[0004] In terms of personnel access, pressurized cabins with a working pressure below 0.2 MPa usually use a side sealing zipper, but when the working pressure is greater than 0.2 MPa, the traditional zipper structure will be difficult to seal, so a metal cabin door is often used to achieve cabin sealing.

[0005] The present application relates to the technical field of pressurized cabin, in particular to a high-strength portable soft pressurized cabin optimization system.

[0006] The present application optimizes the cabin structure of the above-mentioned existing invention to achieve better pressure-bearing effect, and optimizes the control logic of the soft pressurized cabin. SUMMARY

[0007] The present application is directed to the problems and deficiencies of the prior art, and provides a high-strength portable soft pressure cabin optimization system.

[0008] The present application solves the above technical problems by the following technical solutions:

[0009] The present application provides a high-strength portable soft pressure cabin optimization system, which comprises a soft capsule and a pressure-bearing binding assembly, characterized in that the left side of the soft capsule is provided with airtight first cabin penetrating interface corresponding to the placement of the human head inside the cabin, and the right end side is provided with airtight second cabin penetrating interface, and the first cabin penetrating interface and the second cabin penetrating interface are connected by pipeline to the first absorption device.

[0013] The control box is used for receiving cabin gas through the cabin air pressure pipe to detect the cabin pressure, and based on the cabin pressure, the cabin is pressurized through the pressurizing interface or depressurized through the depressurizing interface to make the cabin pressure reach the preset pressure value, and the cabin personnel situation photographed by the camera is received and displayed; when the human body in the cabin breathes by using the cabin gas, the cabin gas is received through the cabin gas sampling pipe to detect the oxygen concentration and carbon dioxide concentration in the cabin, the oxygen supply interface is controlled and adjusted to supplement oxygen in the cabin to make the oxygen concentration in the cabin reach the corresponding preset oxygen concentration, and the first absorption device is controlled and adjusted to absorb carbon dioxide in the cabin to make the carbon dioxide concentration in the cabin lower than the corresponding preset carbon dioxide concentration; when the human body in the cabin breathes by using the mask, the gas in the mask is received through the mask gas sampling pipe to detect the oxygen concentration and carbon dioxide concentration in the mask, the mask oxygen supply pipe is controlled and adjusted to supplement oxygen in the mask to make the oxygen concentration in the mask reach the corresponding preset oxygen concentration, and the second absorption device is controlled and adjusted to absorb carbon dioxide in the mask to make the carbon dioxide concentration in the mask lower than the corresponding preset carbon dioxide concentration.
