[0002] In clinical practice, sandbags are placed on the incisions of some surgical patients after surgery to apply pressure to stop bleeding and reduce swelling. However, most current sandbags are pressed against the incisions by bundling them. This fixation method is not very reliable and can easily cause the sandbags to shift or fall during patient activities. In addition, the pressure on the wound often depends on the weight of the sandbag, and the pressure cannot be adjusted during use, resulting in poor compression effect. Therefore, improvements are urgently needed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, a compression belt for compression hemostasis includes a strap 1, the two ends of the strap 1 are connected by Velcro, a first Velcro hook surface 11 is provided on the inner side of one end of the strap 1, and a first Velcro fleece surface 12 is provided on the outer side of the other end of the strap 1, the first Velcro hook surface 11 and the first Velcro fleece surface 12 are glued and fixed to make the strap 1 form a ring structure, and the two ends of the strap 1 are connected by Velcro, so that the strap 1 can be tied to the patient and fixed.

[0025] An elastic sheet 2 is sewn on the inner side of the strap 1. The elastic sheet 2 is made of elastic fabric and has good elastic deformation effect. A sandbag 4 is connected to the side of the elastic sheet 2 away from the strap 1. The sandbag 4 is fixed to the elastic sheet 2 by Velcro. A second Velcro fur surface 21 is provided on the surface of the elastic sheet 2. The sandbag 4 includes a wrapping bag 42. The wrapping bag 42 is filled with sand 41. A second Velcro hook surface 43 is provided on the outside of the wrapping bag 42. The second Velcro hook surface 43 can be pasted with the second Velcro fur surface 21. When in use, the sandbag 4 is cut according to the cutting method. Choose a sandbag 4 of appropriate size according to the size of the opening, fix the sandbag 4 on the surface of the elastic sheet 2 with Velcro, and then tie the strap 1 to the patient. The strap 1 covers the sandbag 4, and the sandbag 4 and the strap 1 are fixed with Velcro. This not only realizes the detachable design of the sandbag 4, which is convenient for replacing the sandbag 4 and meeting the compression requirements of incisions of different sizes, but also can effectively prevent the sandbag 4 from shifting when the patient moves, with good fixing effect, and can also adjust the position of the sandbag 4 on the surface of the elastic band 2 according to the position of the incision, so as to cope with the compression of incisions in different positions, and the operation is convenient and reliable.

[0026] An installation cavity 10 is provided between the elastic sheet 2 and the strap 1, and an airbag 3 is installed in the installation cavity 10. When the airbag 3 is inflated, the elastic sheet 2 is stretched and the airbag 3 squeezes the sandbag 4, thereby pressurizing the incision. When the airbag 3 contracts, the pressure on the sandbag 4 is reduced, thereby reducing the pressure on the incision and adjusting the pressure at the incision. This allows appropriate pressure to be applied to the incision, reducing the accumulation of blood and other body fluids, thereby reducing the possibility of swelling and pain, and also helps prevent bleeding.

[0027] The airbag 3 can be inflated and deflated through an inflation and deflation valve, which includes a vent tube 5, one end of which is connected to the airbag 3 and the other end of which passes through the surface of the strap 1. An annular pad 52 is provided at the lower portion of the vent tube 5, which is fixed to the inner wall of the airbag 3. An interface 51 is provided on the side of the vent tube 5 located outside the strap 1, and an inflation valve is installed at the upper end of the vent tube 5, which is used to deflate the airbag 3. The interface 51 is an inflation port, which is used to inflate the airbag 3. A one-way valve 9 is installed in the inflation port, which is connected in one direction from the outside to the inside of the vent tube 5. The deflation valve includes a valve cover 6 and a movable plug 7, and the valve cover 6 is fixed to the upper end of the vent tube 5. The movable plug 7 is located in the valve cover 6. The movable plug 7 can move up and down to disengage from or block the upper end of the vent pipe 5. The movable plug 7 includes a plug 71. The plug 71 can be inserted into or disengaged from the vent pipe 5. The valve cover 6 includes a cover body 62. A spring 8 is provided between the lower part of the cover body 62 and the movable plug 7. The two ends of the spring 8 can respectively abut the cover body 62 and the movable plug 7. The valve cover 6 includes an annular sleeve 61. The annular sleeve 61 is connected to the vent pipe 5 by a thread. A plurality of guide grooves 63 are provided between the annular sleeve 61 and the cover body 62. The movable plug 7 is provided with a rib 72 corresponding to the guide groove 63 on its circumference. The rib 72 passes through the corresponding guide groove 63.

[0028] The inflation and deflation valve can inflate and deflate the airbag 3. The pressure inside the airbag 3 can be adjusted by the inflation and deflation valve. When the airbag 3 needs to be inflated, the external air source (which can be an air pump, not shown in the figure) is connected to the interface 51, and the airbag 3 is inflated by the air pump. When the air pump is removed, the one-way valve 9 can prevent the gas in the airbag 3 from leaking out from the interface 51. Since the inflation pressure cannot be effectively controlled during inflation, the deflation valve can be set to serve as a safety measure during inflation. The function of the valve is that when the air pressure in the airbag 3 is too high, the movable plug 7 can move upward and compress the spring 8. At this time, the upper end opening of the vent tube 5 is opened, and deflation can be achieved, thereby effectively preventing the pressure in the airbag 3 from being too high; when the pressure in the airbag 3 needs to be reduced after normal inflation, the operator only needs to hold the rib 72 and pull it upward. The rib 72 can move along the guide groove 63, so that the plug 71 is separated from the upper opening of the vent tube 5. At this time, the upper opening of the vent tube 5 is opened, and manual deflation of the airbag 3 is achieved.

[0029] A first groove 64 is provided at the lower portion of the cover body 62, and a second groove 73 is provided at the upper portion of the movable plug 7. Both ends of the spring 8 are respectively located in the first groove 64 and the second groove 73. Through the above design, the spring 8 can be limited to prevent the spring 8 from detaching, making the structure more reliable.
