Description

Technical Field

[0001] The invention belongs to the technical field of rescue equipment, and in particular relates to a device for transporting critically injured patients in high altitude and cold areas. Background Art

[0002] Rescue and transfer equipment used in plateaus needs to be pressurized to restore the wounded to a quasi-plain state, thereby preventing the wounded from further deteriorating their pulmonary edema and cerebral edema. Common medical wounded transfer equipment that requires pressurization basically includes two types: pressurized cabins for use on land and rescue cabins for diving. In the prior art, there is no air cushion inside the cabin of the pressurized cabin used on land, and the wounded can only lie flat on the lower curved surface of the cabin. This design is mainly limited by the elastic deformation, quality, and peeling strength of the inner cabin wall material. The 180° opening cabin design is inconvenient for the wounded to enter and exit the cabin due to the opening size limitation; in addition, when the cabin is pressurized, it can only be manually pressurized by looking at the pressure gauge on the cabin, and the cabin does not have insulation and heating properties. The rescue cabin for diving is basically the same as that used on land. Because higher pressure is required, only a metal head is set at the end of the cabin. The wounded enter and exit from the end, which is very inconvenient and not suitable for transporting the wounded. Therefore, it is necessary to improve the existing wounded transfer equipment.

The inner cabin unit includes an inner upper cabin body 4 and an inner lower cabin body 5, and the inner upper cabin body is hinged to the inner lower cabin body on one side, and the other side is connected by an inner sealing zipper, and the outer cabin unit includes an outer upper cabin body 21 and an outer lower cabin body 22, and the outer upper cabin body is hinged to the outer lower cabin body on one side, and the other side is connected by an outer sealing zipper; the outer upper cabin body and the outer lower cabin body both include a main body 6 and a head 7 on both sides, and the inflation port and the air release port are arranged on the head. Rubber strips or sealing gaskets are respectively provided on the corresponding ends of the cabin body of the inner cabin unit or the outer cabin unit, so that the sealing can be maintained when the cabin body is closed. As a further improvement scheme, a sealing zipper can also be provided on the head. After the cabin body is closed, the sealing zipper can be pulled up to ensure the sealing of the cabin body.

[0030] A thermal insulation layer 12 is provided between the inner upper cabin and the outer upper cabin, and between the inner lower cabin and the outer lower cabin. The thermal insulation layer can be an aerogel composite material, or a polymer material such as a hollow fiber, which effectively shields the temperature heat conduction between the outside and inside of the cabin. The thermal insulation layer can be compounded on the outer surface of the inner cabin, or on the inner surface of the outer cabin. Specifically, it can be fixed by gluing or other methods, which will not be described in detail here.

[0031] The inner side of the lower cabin of the inner cabin is provided with a cabin air cushion 13, and the side wall of the lower cabin of the inner cabin is provided with a binding belt assembly; the outer upper cabin of the outer cabin unit is provided with a stretcher rod 14 on both sides of the outer lower cabin. The base material of the inner and outer cabin units is a base cloth woven from polyester, which is cut and formed by high-frequency welding, and a sealing zipper is welded at the corresponding cabin opening. The base cloth should have good elastic deformation performance, and the basic composite TPU has high peeling strength. As an example, the base cloth is woven at 45° with polyester or nylon material with good tensile properties, so that the warp and weft deformation of the fabric are coordinated and tend to be consistent. The cast TPU process with the highest peeling strength is used on both sides of the base cloth, which can obtain good sealing performance while taking into account the peeling strength after high-frequency welding. The base cloth used to make the cabin is cut and formed by high-frequency welding to form the cabin. In a further improved scheme, a rainproof coating is provided on the inner side of the outer cabin fabric to ensure use in snowy and rainy environments. At the same time, the polyester fabric of the outer cabin is made of multi-strand reinforced polyester filaments, so that the outer layer of the cabin should have good anti-scratch performance to ensure that it will not be damaged by accidental scratches during lifting.
