When working, the pressurized airbag 31 is first pulled forward, and the air pipe 33 inside the installation box 30 will be straightened. In the process of being straightened, the air pipe 33 will push the long plate 57 abutting against the air pipe 33 to rotate, and the bottom end of the long plate 57 is connected to the arc plate 56, so it will drive the arc plate 56 to rotate along The long plate 57 slides along the rotating shaft, wherein the rotating shaft of the long plate 57 is located on the side of the long plate 57 away from the arc plate 56. A connecting piece is fixed to the bottom end of the long plate 57 and connected to the arc plate 56. The arc plate 56 drives the second gear 55 to rotate, and the second gear 55 meshes with the rack 51, thereby driving the rack 51 to move, and the first gear 48 and the second gear 55 are both meshed with the rack 51, so the first gear 48 will also rotate synchronously. During the rotation of the first gear 48, the threaded rod 47 connected to the top thereof will rotate, so that the moving block 46 threadedly connected to the threaded rod 47 moves upward, and the moving block 46 is moved upward. A guide column 42 is inserted to guide the movement of the moving block 46, wherein the moving block 46 is provided with a protrusion for connecting with the guide column 42, and an extrusion block 45 is fixed on the moving block 46. When the extrusion block 45 moves upward with the moving block 46, it no longer abuts against the top of the gas pipe 33, thereby releasing the extrusion of the gas pipe 33. At this time, the gas can be smoothly delivered to the inside of the expansion airbag 24 by squeezing the pressurized airbag 31, wherein a rubber sheet 58 is fixed on one side of the long plate 57 close to the gas pipe 33, and the rubber sheet 58 can reduce the wear between the gas pipe 33 and the long plate 57, and stop bleeding The front side of the band 1 is a hemostatic dressing.

The bottom end of the inflatable airbag 24 is fixed on the fixing ring 27, and the fixing ring 27 slides on the wrapping band 20 so as to adjust the position of the inflatable airbag 24 by moving the fixing ring 27.

[0024] Further, the reset mechanism includes a support column 54, the support column 54 passes through the connecting plate 50, the front and rear sides of the support column 54 are fixedly connected to the inner wall of the installation box 30, and the support column 54 is sleeved with a first spring 53, and the two sides of the first spring 53 are respectively fixedly connected to the inner wall of the installation box 30 and the connecting plate 50; Through the structural design of the reset mechanism, in the process of pulling the pressurized airbag 31 outward, the air pipe 33 inside the installation box 30 can be smoothly extended outward, and when the pressurized airbag 31 is not pulled, the extended air pipe 33 can be quickly stored in the installation box 30 under the action of the first spring 53, so that the air pipe 33 can be quickly reset. When working, the rack 51 is fixed on the connecting plate 50, and the connecting plate 50 is penetrated by the support column 54 and slides on the support column 54. When the arc plate 56 drives the second gear 55 to rotate, the connecting plate 50 will slide on the support column 54, and the first spring 53 set on the support column 54 will be compressed. When the pressurized airbag 31 is no longer pulled, the first spring 5 3 will push the connecting plate 50 to reset, thereby driving the first gear 48 and the second gear 55 to rotate in the opposite direction, and the moving block 46 will gradually move downward until the extrusion block 45 fixed on the moving block 46 is squeezed together with the gas pipe 33, wherein a fixed block 41 is arranged directly below the extrusion block 45, so that when the extrusion block 45 squeezes the gas pipe 33, the fixed block 41 can provide support for the bottom end of the gas pipe 33, and the reverse rotation of the second gear 55 will also drive the arc plate 56 to move to reset the long plate 57. Since the long plate 57 is in contact with the gas pipe 33, the long plate 57 will continuously push the gas pipe 33 when resetting, so that the part of the gas pipe 33 extending out of the installation box 30 can be re-stored into the installation box 30.

[0025] Further, the second extrusion mechanism includes a moving rod 63, the moving rod 63 is L-shaped, the moving rod 63 is slidably connected to the inside of the slide slot 44, the slide slot 44 is opened on the partition 37, the inner wall of the slide slot 44 is fixedly connected with a guide rod 43, the guide rod 43 passes through the moving rod 63, a second spring 65 is sleeved on the guide rod 43, the second spring 65 is fixedly connected to the moving rod 63, the bottom end of the moving rod 63 is fixedly connected with an abutment block 62, the abutment block 62 abuts with a top block 66, the abutment block 62 and the top block 66 are both trapezoidal in design, one side of the top block 66 is slidably connected to the support frame 61, the bottom end of the support frame 61 is fixedly connected to the inner wall of the installation box 30, the bottom end of the top block 66 is rotatably connected with a push rod 60, the push rod 60 is rotatably connected to the connecting rod 59, and the connecting rod 59 is rotatably connected to the bottom end of the first gear 48; Through the structural design of the second squeezing mechanism, when the pressurized airbag 31 is used to inflate the expandable airbag 24, the moving rod 63 will be separated from the air pipe 33, thereby releasing the squeezing of the air pipe 33, so that the gas can smoothly pass through the air pipe 33 and the connecting pipe 29 to flow into the expandable airbag 24. Since the second squeezing mechanism is closer to the connection between the connecting pipe 29 and the air pipe 33, the air pipe 33 can be squeezed by the moving rod 63 to cooperate with the duckbill valve 35 to achieve the purpose of reducing gas escape. During operation, when the first gear 48 is rotating, the connecting rod 59 connected to its bottom end will pull the push rod 60 to move, and the top block 66 fixed on the push rod 60 will approach the abutment block 62 and abut against the abutment block 62, and the abutment block Both the abutment block 62 and the top block 66 are trapezoidal in design, the abutment block 62 will be pushed to slide to one side, the second spring 65 will be compressed, and the moving rod 63 fixed on the abutment block 62 will move away from the gas pipe 33. The moving rod 63 is penetrated by the guide rod 43, and the stability of the movement of the moving rod 63 can be ensured by the guide rod 43. Similarly, when the first gear 48 rotates in the opposite direction, the top block 66 will gradually move away from the abutment block 62, the second spring 65 will push the moving rod 63 to reset, and the top of the moving rod 63 will squeeze the gas pipe 33 again. Since the moving rod 63 is close to the duckbill valve 35, it can cooperate with the duckbill valve 35 to reduce gas escape. The bottom end of the first gear 48 does not contact the partition 37, and there is enough spacing to ensure the normal rotation of the connecting rod 59.

[0026] Furthermore, the rear ends of the connecting plate 50 and the rack 51 are fixedly connected with a cushion block 49, the cushion block 49 is made of rubber material, and the cushion block 49 is penetrated by a support column 54; During operation, the cushion block 49 is made of rubber material and is used for buffering the rear ends of the connecting plate 50 and the rack 51 and the inner wall of the installation box 30 to prevent the connecting plate 50 and the rack 51 from abutting against the inner wall of the installation box 30 .

[0027] Furthermore, two sets of guide wheels 39 and three sets of fixing columns 38 are fixedly connected to the top of the partition 37, the air pipe 33 is wound around the guide wheel 39, and the fixing columns 38 are in contact with the air pipe 33; During operation, the air pipe 33 is wound around the guide wheel 39 and cooperates with the fixing column 38 to keep the air pipe 33 in a taut state to prevent the air pipe 33 from being too loose, resulting in the air pipe 33 being unable to stably drive the long board 57 to rotate when the air bag 31 pulls the air pipe 33.

[0028] Furthermore, the front end of the installation box 30 is fixedly connected with an extension column 34, and the extension column 34 is sleeved on the gas pipe 33.

The rear end of the air pipe 33 is clamped on the mounting box 30 through two sets of mounting rings 36 to ensure that when the pressurized airbag 31 is pulled, the rear end part of the air pipe 33 can remain fixed to avoid pulling on the connecting pipe 29.

[0029] Furthermore, two groups of arc-shaped gaskets 26 are fixedly connected to the bottom end of the expansion airbag 24, and the bottom ends of the arc-shaped gaskets 26 are in contact with the top ends of the wrapping belt 20; During operation, the bottom end of the inflatable airbag 24 is fixed to the fixing ring 27 by gluing. Since the fixing ring 27 slides on the winding belt 20, in order to avoid the bottom end of the inflatable airbag 24 from being suspended in the air, two groups of arc-shaped gaskets 26 are also fixed to the bottom end of the inflatable airbag 24 so that the bottom end of the inflatable airbag 24 can contact with the winding belt 20. After applying adhesive to the bottom end of the arc-shaped gasket 26, the fixing effect of the inflatable airbag 24 can be improved. Embodiment 2
