[0027] Example three, on the basis of example two, referring to Figure 3The pagoda-shaped airbag protection scheme: The airbag 201 can be formed by fixing and stacking multiple sheet-like airbag units 203 into a pagoda shape. Each layer of sheet-like airbag units 203 has a vent hole in the middle to form an air circulation channel. The first inflation pipeline is equipped with either a mechanical pressure gauge or an electronic pressure measuring gauge. The airbag 201 can be integrally formed, or the layers of sheet-like airbag units 203 can be fixed together by mutual bonding, welding, heat fusion, sewing, etc. This utility model adopts a multi-layer pagoda-shaped structure for the inflatable airbag design; it achieves a larger compression distance ratio, a longer stroke, high inflation efficiency, and is flexible indentation with precise compression direction, occupying little space. It solves the technical defects of existing nested inflatable airbags, which are limited by the maximum bottom circle diameter due to the nested structure, resulting in a small stroke. The pagoda-shaped pushing airbag structure is composed of large-area mutual bonding between each layer of sheet-like airbags, leaving a small gas channel in the middle. It can use a large number of layers of sheet-like airbags stacked together, each layer The airbags are very thin, allowing for a large range of expansion and contraction during inflation and compression. Furthermore, the extensive bonding between the layered airbags ensures a fixed overall direction of expansion, preventing deviation when pressing on objects after inflation and facilitating directional and fixed pressure. Overall performance is excellent, and the design is simple and portable. A base plate can be installed at the bottom of the airbag, and a top plate can be installed at the top.

Air passages are opened at the joints for interconnection. Because the individual airbag units are interconnected at their outer peripheries, the direction of the airbag is fixed during expansion and contraction, allowing for directional compression and hemostasis. This invention uses an inflatable airbag design where each individual airbag unit has a hollow center, and the individual airbag units are interconnected by overlapping outer peripheries. Each layer of airbag is very thin, allowing for a large range of expansion and contraction during inflation and compression. Simultaneously, because the layered airbags are largely bonded together, the overall expansion direction of the airbag is fixed, and the direction is less likely to deflect when compressing an object after inflation, facilitating directional and fixed compression. The overall performance is excellent, and it is simple and portable. The airbag can be multi-layered, such as five, six, seven, or eight layers, and the cross-sectional shape can be circular, elliptical, or polygonal.

[0029] Example 5 differs from Example 3 in that it employs a parallel airbag protection scheme: the airbag 201 is composed of multiple airbag units connected in parallel. These units are interconnected through air passages on the base plate. After inflation, the expansion of each unit causes mutual traction and integration, providing coordinated support and enabling the airbag body to achieve directional expansion and contraction compression. This invention utilizes an inflatable airbag design composed of multiple airbag units connected in parallel. Each layer of airbag is very thin, allowing for a large range of expansion and contraction during inflation. Furthermore, the large-area bonding of the layered airbags ensures a fixed overall expansion direction, preventing deviation when compressing objects after inflation and facilitating directional and fixed compression. The overall performance is excellent, and the design is simple and portable. The airbag can be multi-layered, such as five, six, seven, or eight layers, and its cross-sectional shape can be circular, elliptical, or polygonal.

A sound-emitting part 404 is fixedly connected inside the hollow receiving cavity 403. The second connector 405 is elastically connected to the hollow receiving cavity 403 of the first connector 401. When the tension of the fixing band gradually increases, the second connector 405 generates elastic displacement inside the hollow receiving cavity 403 of the first connector 401. When the tension reaches 130N~145N, the second connector 405 triggers the sound-emitting part 404 to generate a sound, prompting the rescuers that the pelvis 3 is fixed in place. This utility model employs a connecting strap with a first and a second connector at both ends, which are respectively connected to a pelvic fixation buckle. After being fixed around the groin junction, the femoral artery is compressed and hemostasis is achieved by applying pressure to the femoral artery through a directional compression airbag. The pelvic fixation buckle tightens the pelvis with a certain force, solving the technical defects of existing spring buckles, which are large in size, complex in structure, require drilling holes in the connecting strap, reduce the strength of the connecting strap, and are inconvenient to use. The buckle structure is protective. When the tension gradually increases, the elastic component in the buckle cavity generates elastic displacement.
