Referring to fig. 6, the inflatable cushion 71 includes an inflatable sleeve 710, an air inlet tube 711 and a second elastic member 715, the air inlet tube 711 is symmetrically disposed at two ends of the inflatable sleeve 710, the air inlet tube 711 is disposed inside the inflatable sleeve 710, and the outer diameter of the air inlet tube 711 is smaller than the inner diameter of the inflatable sleeve 710. A blocking ball 712 is provided inside the intake duct 711, and the outer diameter of the blocking ball 712 is larger than the inner diameter of both end portions of the intake duct 711 and smaller than the diameter of the middle portion of the intake duct 711. In the initial state, the inflatable cushion 71 is compressed, the air inside the inflatable cushion is exhausted through vacuum treatment, at the moment, the blocking ball 712 is arranged at the outer end part of the air inlet pipe 711, the external air can be blocked from entering the inflatable sleeve 710, the occupied space of the inflatable cushion 71 is reduced, and the binding belt 7 is easy to wind. In addition, the blocking ball 712 is connected to the first elastic member 714 through the connecting member 713, the first elastic member 714 is disposed inside the inflatable sleeve 710 in an inverted "eight" shape, and the first elastic member 714 and the inflatable sleeve 710 are connected by gluing. When the inflatable cushion 71 is compressed, the distance between the first elastic member 714 and the inflatable sleeve 710 is reduced, and the included angle between the adjacent first elastic members 714 is gradually increased until reaching 180 degrees. The second elastic members 715 are disposed between the adjacent first elastic members 714, wherein the second elastic members 715 are disposed in a direction opposite to the direction in which the first elastic members 714 are disposed, and the second elastic members 715 are disposed to assist the first elastic members 714 to return, so that the air intake efficiency of the inflatable cushion 71 is increased. The intake duct 711 is in the shape of a constricted portion having a large diameter at the center and small diameters at the opposite ends. When the inflatable cushion 71 is restored by the first and second

elastic members

714 and 715, the blocking ball 712 is gradually pulled toward the inner end of the air inlet duct 711 by the connection member 713. In the gradual resetting process of the first elastic member 714 and the second elastic member 715, external air is automatically sucked into the inflating sleeve 710 through the air inlet pipe 711 until the blocking ball 712 blocks the inner end part of the air inlet pipe 711, air inlet is stopped, at the moment, the air in the inflating pad 71 is not completely filled, the bandage 7 is wound on the leg of the patient again, the squeezing pad 72 squeezes the middle part of the inflating pad 71, and the air pushes the inflating pad 71 to bulge outwards, so that the squeezing resisting effect of the bandage 7 is achieved.

The working principle is as follows: in the initial state, the air in the inflatable cushion 71 on the bandage 7 is exhausted and extruded and wound on the sliding block 6, when in use, the leg of the patient passes through the right support plate 3 and is inserted between the right support plate 3 and the left support plate 2, the sole plate of the patient is contacted with the butt strap 4, and the driving motor 8 is started; under the action of the driving motor 8, the fluted disc 11 rotates, and due to the meshing action of the gear 10, the gear ring 9 and the fluted disc 11, the gear 10 can rotate and can rotate around the outer side of the fluted disc 11; in the process of the rotation of the gear 10, the sliding block 6 on the transmission screw 5 can move axially along the center of the transmission screw 5, the fracture wound part of the patient is wrapped around automatically through the binding band 7, and the automation degree is high.

Meanwhile, in the process of wrapping the binding band 7 around the patient, after the binding band 7 is separated from the sliding block 6 and wound, the first elastic member 714 and the second elastic member 715 in the inflatable cushion 71 are reset, the blocking ball 712 in the air inlet pipe 711 is pulled to move from the outer end to the inner end of the air inlet pipe 711, in the moving process of the blocking ball 712, the blocking ball 712 is separated from the air inlet of the air inlet pipe 711, the inflatable sleeve 710 continuously and automatically sucks external air into the inflatable cushion 71, the air is inflated through air intake, when the blocking ball 712 moves to the inner end of the air inlet pipe 711 and blocks the inner end of the air inlet pipe 711, the inflation of the interior of the inflatable sleeve 710 can be automatically stopped, manual operation is not needed, after the inflated binding band is wound around the leg of the patient, the inflatable cushion 71 is squeezed through the squeezing cushion 72 again, and the inflatable cushion 71 can achieve a better anti-squeezing effect.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
