[0001] The present invention relates to the technical field of auxiliary bandaging devices, in particular to an inflatable wrist pressure hemostasis auxiliary bandaging device. Background Art
[0002] With the acceleration of global industrialization and the increasing incidence of various accidents, trauma emergency care has become an indispensable and critical component of the modern medical system. Among the many technical methods used in trauma emergency care, pressure bandaging, as a basic and effective method for hemostasis, is widely used in battlefield first aid, traffic accident rescue, and everyday accident handling.
[0003] However, traditional pressurization pressure mainly relies on the operator's experience and feeling to adjust, which can easily cause the pressure to exceed the maximum safety value, thereby causing secondary damage to the patient. At the same time, the volume of the inflatable part of the strap of the device is fixed. When wrapping wrists of different thicknesses, the fixed volume cannot quickly adapt to different sizes, resulting in a slow inflation process and unable to meet the timeliness requirements of emergency hemostasis. In response to the above problems, the inventors proposed an inflatable wrist pressurized hemostasis auxiliary bandage device to solve the above problems. Summary of the Invention

[0006] Preferably, the adjusting assembly includes a telescopic rod, which movably passes through the fixed cylinder and the regulating valve, and the side of the telescopic rod is fixedly connected with a spline, one end of the fixed cylinder is provided with a key slot, and the spline is slidably engaged in the key slot, and one end of the telescopic rod is fixedly connected with a clamping plate, one side of the fixed cylinder is provided with a cross slot, and the clamping plate is clamped in the cross slot, and the end of the telescopic rod away from the clamping plate is fixedly connected to a limiting block, and a return spring is provided between the side of the limit block close to the telescopic rod and the inner wall of the regulating valve, and the return spring is movably sleeved on the outside of the telescopic rod.
[0007] Preferably, the guide assembly includes a sealing ring, which is fixedly connected to the inner side of the front end of the manual inflation ball, and a guide plate is fixedly connected to the side of the inner side of the front end of the manual inflation ball close to the sealing ring. A guide rod is movably passed through the guide plate, and a piston is fixedly connected to the end of the guide rod close to the sealing ring. The piston is used to seal the inner ring of the sealing ring, and a spring is provided between the guide plate and the sealing ring, and the spring is movably sleeved on the outer side of the guide rod.
[0008] Preferably, the top of the front end of the manual inflatable ball is fixedly connected to a U-shaped tube that communicates with the inside of the rubber tube, and a movable plate is slidably clamped on one side of the inside of the U-shaped tube.

[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. Adjust the length of the inflatable bandage according to the thickness of the wrist being bound. When the wrist is thin, turn the regulating valve to stagger the position of the regulating valve and the vent hole on the fixed tube. This prevents the gas inside the inflatable bandage on one side of the fixed tube from flowing to the inside of the inflatable bandage on the other side of the fixed tube, reducing the volume of air in the use area and more quickly increasing the pressure inside the inflatable bandage. When the wrist is thick, align the position of the vent hole on the fixed tube with that on the regulating valve, so that the inflatable bandages on both sides of the fixed tube are connected, further improving the efficiency of hemostasis.
[0011] 2. When the air pressure inside the inflatable strap increases, the air pressure pushes the movable plate to move toward the side of spring 2, compressing spring 2 so that the stop block extends into the interior of the manual inflatable ball. When the pressure reaches the set value, the stop block extends to contact one side of the piston, thereby limiting the opening of the piston and inhibiting further pressurization, further improving the safety of the equipment.

[0023] The adjustment assembly 5 includes a telescopic rod 51, which movably passes through the fixed cylinder 2 and the regulating valve 3. A spline 53 is fixedly connected to the side of the telescopic rod 51. A key slot 52 is provided at one end of the fixed cylinder 2, and the spline 53 slides and is engaged in the key slot 52.
[0024] By adopting the above technical solution, through the cooperation between the keyway 52 and the spline 53, the telescopic rod 51 can be telescopically slid relative to the regulating valve 3, and the regulating valve 3 can rotate with the rotation of the telescopic rod 51, thereby adjusting the position of the fixed cylinder 2 and the vent hole 4 on the regulating valve 3 to correspond or stagger.
[0025] One end of the telescopic rod 51 is fixedly connected to a clamping plate 54 . A cross slot 55 is formed on one side of the fixing tube 2 , and the clamping plate 54 is clamped in the cross slot 55 .
[0026] By adopting the above technical solution, through the cooperation between the clamping plate 54 and the cross groove 55, when the clamping plate 54 is clamped into the inside of the cross groove 55, the rotation of the clamping plate 54 can be limited.
[0027] One end of the telescopic rod 51 away from the clamping plate 54 is fixedly connected to the limit block 56. A return spring 57 is provided between the side of the limit block 56 close to the telescopic rod 51 and the inner wall of the regulating valve 3. The return spring 57 is movably sleeved on the outside of the telescopic rod 51.
[0028] By adopting the above technical solution and providing the reset spring 57 , the limit block 56 can be easily reset, and a pre-tightening force can be provided to the clamping plate 54 at the same time.
[0029] The guide assembly 8 includes a sealing ring 81, which is fixedly connected to the inner side of the front end of the manual inflatable ball 7. A guide plate 84 is fixedly connected to the side of the inner side of the front end of the manual inflatable ball 7 close to the sealing ring 81. A guide rod 83 is movably passed through the guide plate 84. A piston 82 is fixedly connected to the end of the guide rod 83 close to the sealing ring 81. The piston 82 is used to seal the inner ring of the sealing ring 81. A spring 85 is provided between the guide plate 84 and the sealing ring 81. The spring 85 is movably sleeved on the outer side of the guide rod 83.
[0030] By adopting the above technical solution, the inflation of the inside of the inflatable bandage 1 is achieved by repeatedly pressing the manual inflatable ball 7. During squeezing, the piston 82 is pushed toward one side of the guide plate 84 under the action of the internal air pressure of the manual inflatable ball 7, and the spring 1 85 is compressed to form a gas flow channel between the piston 82 and the sealing ring 81, thereby achieving gas filling and suppressing the backflow of gas inside the inflatable bandage 1.
[0031] The top of the front end of the manual inflatable ball 7 is fixedly connected to a U-shaped tube 91 that communicates with the inside of the rubber tube 6. A movable plate 92 is slidably clamped on one side of the inside of the U-shaped tube 91. The bottom end of the movable plate 92 is fixedly connected to a stop block 93. The bottom end of the stop block 93 is movably extended to the inside of the manual inflatable ball 7. A spring 2 94 is provided between the bottom surface of the movable plate 92 and the top surface of the manual inflatable ball 7. The spring 2 94 is movably sleeved on the outside of the stop block 93. A through hole 96 is provided on the side of the bottom end of the U-shaped tube 91 near the spring 2 94.
[0032] By adopting the above technical solution, when the air pressure inside the inflatable strap 1 increases, under the action of the air pressure, the movable plate 92 is pushed to move toward the side of the spring 2 94, and the spring 2 94 is compressed, so that the stop block 93 extends into the interior of the manual inflatable ball 7. When the pressure reaches the set value, the stop block 93 extends to contact one side of the piston 82, thereby limiting the opening of the piston 82 and inhibiting the continued pressurization operation.
[0033] A limiting ring 95 is fixedly connected inside the U-shaped tube 91 and above the movable plate 92 .
[0034] By adopting the above technical solution and providing the limiting ring 95 , the position of the movable plate 92 can be limited.
[0035] A hook surface 10 is provided on the inner side of the inflatable bandage 1 away from the rubber tube 6 , and a rough surface 11 is provided on the outer side of the inflatable bandage 1 in an area corresponding to the hook surface 10 .
[0036] By adopting the above technical solution, the cooperation between the hook surface 10 and the fleece surface 11 can facilitate better fixing of the inflatable strap 1 to the outside of the wrist. At the same time, by changing the fitting position of the hook surface 10 on the fleece surface 11, the tightness of the inflatable strap 1 can be adjusted.
[0037] Working principle: When applying pressure to stop bleeding on the wrist, the inflatable bandage 1 is fixed to the outside of the wrist through the cooperation between the hook surface 10 and the fur surface 11, and the use length of the inflatable bandage 1 is adjusted according to the thickness of the wrist. When the wrist is thin, the regulating valve 3 is rotated to stagger the position of the regulating valve 3 and the vent 4 on the fixed tube 2, thereby inhibiting the gas inside the inflatable bandage 1 on one side of the fixed tube 2 from flowing to the inside of the inflatable bandage 1 on the other side of the fixed tube 2, reducing the volume of the inflated area, and being able to increase the pressure more quickly. The pressure inside the inflatable strap 1 is increased, and the clamping plate 54 is clamped to the inside of the cross groove 55, thereby inhibiting the rotation of the telescopic rod 51. When the wrist is thick, the telescopic rod 51 is pulled away from the fixed cylinder 2 to make the clamping plate 54 withdrawn from the inside of the cross groove 55. The spline 53 and the keyway 52 cooperate with each other to rotate the telescopic rod 51, driving the regulating valve 3 to rotate, so that the fixed cylinder 2 and the vent hole 4 on the regulating valve 3 are aligned, thereby making the interior of the inflatable strap 1 on both sides of the fixed cylinder 2 communicate with each other.
[0038] When pressurizing, the air inside the inflatable bandage 1 is inflated by repeatedly pressing the manual inflatable ball 7. When squeezing, the air pressure inside the manual inflatable ball 7 pushes the piston 82 toward the side of the guide plate 84 and compresses the spring 1 85, forming a gas flow channel between the piston 82 and the sealing ring 81, thereby allowing gas to be filled and suppressing the backflow of gas inside the inflatable bandage 1.
[0039] When the air pressure inside the inflatable strap 1 increases, under the action of the air pressure, the movable plate 92 is pushed to the side of the spring 2 94 and the spring 2 94 is compressed, so that the stop block 93 extends into the interior of the manual inflatable ball 7. When the pressure reaches the set value, the stop block 93 extends to contact one side of the piston 82, thereby limiting the opening of the piston 82 and inhibiting the continued pressurization operation.
[0040] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
