[0077] In this embodiment, the telescopic pad 82 is circular in shape, and its cross-sectional shape on the positioning plate 81 is arc-shaped. The inner side of the telescopic pad 82 is filled with foaming agent powder 83. When the foaming agent powder 83 is mixed with water, it can quickly foam and expand, adjusting the volume of the telescopic pad 82. When the foaming agent powder 83 foams and expands, it can drive the telescopic pad 82 to contact the bony prominences and concave areas of the patient, facilitating pressure hemostasis and covering bandage operations. The hemostatic dressing pad 7 on the surface of the perineal pouch 6 can be replaced and its position adjusted to facilitate contact with the patient's wound and hemostasis operations. The hemostatic dressing pad 7 can be fully in contact with the patient's wound, and its position can be fixed to ensure that it is always in full contact with the patient's wound. The water in the water bag 85 can be quickly and evenly discharged through the drain hole 86 by adjusting the component 88, so that the water comes into contact with the foaming agent powder 83, and the foaming agent powder 83 foams and expands, adjusting the volume of the telescopic pad 82. The perineal pocket 6 has two layers, and the auxiliary compression component 8 is located between the two layers of the perineal pocket 6. The auxiliary compression component 8 is circular in shape and can be removed from the inside of the perineal pocket 6. The position of the auxiliary compression component 8 can be adjusted from the inside of the perineal pocket 6, making it convenient to be placed on the patient's wound.

[0078] The second hemostatic airbag 44 can also be installed inside the perineal pouch 6. Multiple second hemostatic airbags 44 can be assembled to achieve full contact between the hemostatic dressing pad 7 and the patient's wound.

[0079] In one embodiment of the present invention, please refer to Figure 6 , Figure 7 and Figure 8 The adjustment component 88 includes:

[0080] The movable rod 881 is fixedly installed with the sealing plug 87 and located inside the positioning ring 84. A limit assembly 882 is installed between the movable rod 881 and the positioning plate 81 to limit the movement trajectory of the movable rod 881 and adjust the position of the movable rod 881.

[0081] A drive rod 883 is installed in the middle of the positioning plate 81. The drive rod 883 is fixedly connected to the middle of the positioning plate 81. A drive tooth 884 is fixedly installed at one end of the drive rod 883 inside the positioning ring 84. A connecting component 885 is installed between the drive tooth 884 and the moving rod 881. This component is used to move the moving rod 881 when the drive rod 883 and the drive tooth 884 rotate, so that the sealing plug 87 is away from the drain hole 86.

[0082] In this embodiment, one end of the moving rod 881 is connected to the sealing plug 87, and the other end is connected to the connecting assembly 885. The sealing plug 87 is frustum-shaped to facilitate sealing the drain hole 86. Multiple sets of the drain hole 86, sealing plug 87, limiting assembly 882, and connecting assembly 885 are provided and evenly distributed on the positioning ring 84 and positioning plate 81. When the driving rod 883 is manually rotated, the driving gear 884 can be rotated. The connecting assembly 885 can be used to move multiple sealing plugs 87 away from the drain hole 86 at the same time, so that the water in the water bag 85 can be evenly contacted with the foaming agent powder 83.

[0083] In one embodiment of the present invention, please refer to Figure 6 , Figure 7 and Figure 8 The limiting component 882 includes:

[0084] A slide rail 8821 is fixedly installed on a positioning plate 81 and located inside a positioning ring 84. A moving block 8822 is installed inside the slide rail 8821. The moving block 8822 is fixedly connected to the outer wall of a moving rod 881. The moving block 8822 and the slide rail 8821 are connected in a concave-convex manner to ensure that the moving rod 881 always moves along the inner side of the slide rail 8821. A second elastic element 8823 is installed between the moving block 8822 and the inner side of the slide rail 8821.

[0085] In this embodiment, the second elastic element 8823 can be a spring or rubber, etc. In this embodiment, the second elastic element 8823 is a spring. One end of the second elastic element 8823 is connected to the moving block 8822, and the other end is connected to one end of the inner side of the slide rail 8821. The second elastic element 8823 is located on the inner side of the slide rail 8821 near the drain hole 86. The position of the moving block 8822 on the inner side of the slide rail 8821 can be adjusted to facilitate the adjustment of the position of the moving rod 881. Under the action of the second elastic element 8823, the sealing plug 87 at one end of the moving rod 881 can be tightly connected to the drain hole 86, so that the sealing plug 87 can seal the drain hole 86. At this time, the water in the water bag 85 cannot come into contact with the foaming agent powder 83 on the outside of the positioning ring 84.

[0086] The movable block 8822 has an inverted T-shaped cross-section. The movable block 8822 is connected to the inner side of the slide rail 8821 with concave and convex connections. The movable block 8822 can slide along the inner side of the slide rail 8821, further limiting the movement trajectory of the movable rod 881, so that the movable rod 881 always moves in a straight line when it moves, which facilitates the connection and separation of the sealing plug 87 and the drain hole 86 on the positioning ring 84.

[0087] In one embodiment of the present invention, please refer to Figure 6 , Figure 7 and Figure 8 The connection component 885 includes:

[0088] A fixed rod 8851 is mounted on the positioning plate 81 and located on the side of the drive rod 883. A connecting tooth 8852 is mounted on the outer side of the fixed rod 8851. The connecting tooth 8852 is rotatably connected to the fixed rod 8851. A first rotating frame 8853 is mounted on the surface of the connecting tooth 8852. A connecting rod 8854 is mounted on the outer side of the first rotating frame 8853. A second rotating frame 8855 is mounted on the end of the connecting rod 8854 away from the first rotating frame 8853. The second rotating frame 8855 is fixedly connected to the moving rod 881.

[0089] In this embodiment, the fixed rod 8851 is fixedly installed on the positioning plate 81 and located on the side of the drive rod 883. A rolling bearing is installed between the fixed rod 8851 and the connecting tooth 8852. The connecting tooth 8852 can rotate stably on the fixed rod 8851. The connecting tooth 8852 meshes with the drive tooth 884. A first rotating frame 8853 is fixedly installed on the side of the connecting tooth 8852 away from the fixed rod 8851. The first rotating frame 8853 is located away from the center of the connecting tooth 8852. A rolling bearing is installed between the first rotating frame 8853 and the connecting rod 8854. A second rotating frame 8855 is fixedly installed on the end of the moving rod 881 away from the sealing plug 87. A rolling bearing is also installed between the second rotating frame 8855 and the connecting rod 8854. When the connecting tooth 8852 rotates, the first rotating frame 8853 rotates. The position of 53 is adjusted to allow the moving rod 881 to move along the slide rail 8821, facilitating the separation of the sealing plug 87 from the drain hole 86 by the moving rod 881. This allows water in the water bag 85 to drain through the drain hole 86 and facilitates contact with the foaming agent powder 83. A handle is fixedly installed at one end of the drive rod 883 extending from the positioning plate 81, allowing manual rotation of the drive rod 883. This further enables the drive teeth 884 to rotate. The connecting assembly 885 has multiple connecting teeth 8852 that are meshed with the drive teeth 884. When the drive teeth 884 rotate, they simultaneously drive multiple connecting teeth 8852 to rotate, facilitating the simultaneous separation of multiple sealing plugs 87 from the drain hole 86. This ensures that the water in the water bag 85 contacts the foaming agent powder 83 evenly, allowing the foaming agent powder 83 to foam and expand rapidly and evenly.

[0090] The working principle of this invention is:

[0091] In this invention, firstly, the fixation strap 1 is wrapped around the patient's pelvis and secured with the buckle 2. Then, the connecting strip 32 is manually passed through the positioning frame 34. Under the action of the first elastic element 38, the positioning teeth 36 can fix the position of the rack 33 on the connecting strip 32, further fixing the position of the fixation strap 1 with the limiting strap 31. Then, the output end of the pressurizing inflator 5 is connected to the air inlet 42 of the first hemostatic airbag 41, and the valve 43 is opened to allow gas to enter the first hemostatic airbag 41, making the volume of the first hemostatic airbag 41 larger, fully compressing the large blood vessels in the patient's junction area, and allowing real-time observation of the verticality on the pressure detector. Finally, the second hemostatic airbag 44 is inserted between the fixation strap 1 and the patient's wound. The second hemostatic airbag 44 is inflated by pressing the inflator 5, allowing the hemostatic dressing pad 7 to fully contact the patient's wound. When there is a wound in the patient's perineal area or buttocks, the connecting tooth 8852 can be rotated on the fixed rod 8851 by manually rotating the drive rod 883. The positions of the moving rod 881 and the sealing plug 87 are adjusted by the first rotating frame 8853, the connecting rod 8854 and the second rotating frame 8855, so that the water in the water bag 85 can fully contact the foaming agent powder 83 on the inside of the telescopic pad 82. The foaming agent powder 83 foams and expands, and the volume of the telescopic pad 82 changes, making it easier for the hemostatic dressing pad 7 to contact the patient's bony prominences and concave areas, facilitating the covering and bandaging operation, and making it convenient to use.
