Description

Technical Field

[0001] The utility model relates to the technical field of bandage tourniquets, in particular to a bandage tourniquet. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body and maintaining electrolyte and acid-base balance. At the same time, it removes excess water from the body and returns the purified blood. The whole process is called hemodialysis. After dialysis, use a hemostatic bandage to press the wound for 15 to 20 minutes.

[0003] Bandage tourniquets are often used during hemodialysis. When using existing bandage tourniquets, staff often find that the lengths of existing bandage tourniquets are uniform and cannot be adjusted. Different patients need to choose bandage tourniquets of different sizes according to the thickness of their arms or legs, and arms and legs cannot share the same bandage tourniquet, so patients need to buy bandage tourniquets of different sizes. If the wrong size is purchased, it will cause inconvenience to the patient. Utility Model Content

DETAILED DESCRIPTION

[0027] Embodiment 1, as Figure 1 As shown, a bandage tourniquet comprises a tourniquet body 1.

[0028] Reference Figure 2 and Figure 3The tourniquet body 1 is provided with an adjustment structure 2, which is mainly composed of a connecting groove 21. The connecting groove 21 is opened at one end of the tourniquet body 1. A rotating column 22 is rotatably connected in the connecting groove 21, and an extension belt 23 is fixedly connected to the rotating column 22. The tourniquet body 1 is wrapped around the wound to compress the wound and stop bleeding. The rotating column 22 can be rotated to roll the extension belt 23 around the rotating column 22 or pull out the extension belt 23. The adjustment can be made according to the thickness of the patient's arm or leg, thereby avoiding the problem that the length of the existing bandage tourniquet is uniform. , it cannot be adjusted, which causes inconvenience to the patient. Limiting columns 24 are slidably inserted on both sides of the connecting groove 21. One end of the limiting column 24 is fixedly connected to a connecting rod 25. A clamping block 26 is fixedly connected to the connecting rod 25. Both ends of the rotating column 22 are respectively provided with clamping grooves 27. The sizes of the clamping block 26 and the clamping groove 27 are adapted. When the position of the rotating column 22 is adjusted, the limiting column 24 can be slid so that the clamping block 26 is inserted into the corresponding clamping groove 27, so that the rotating column 22 is limited to prevent the extension belt 23 from shifting during the hemostasis process. The limiting column 24 is away from the connecting rod 25. One end is fixedly connected with a round block 29, and the diameter of the round block 29 is larger than the diameter of the limiting column 24. The round block 29 can prevent the limiting column 24 from sliding out of the limit of the tourniquet body 1 when the connecting rod 25 is pulled. A spring 28 is sleeved on the limiting column 24, and one end of the spring 28 is fixedly connected to the side wall of the connecting groove 21, and the other end of the spring 28 is fixedly connected to the round block 29. When the sliding limiting column 24 makes the block 26 away from the slot 27, the spring 28 is in a contracted state. Therefore, when the position of the rotating column 22 is adjusted, the connecting rod 25 is released, and the block 26 is in a contracted state when the spring 28 returns. It is stuck into the slot 27 under the action of elastic force, making the operation more convenient. A Velcro sub-sticker 210 is fixedly connected to the side of the tourniquet body 1 away from the patient's wound. The Velcro sub-sticker 210 is located on the side of the tourniquet body 1 away from the connecting slot 21. A Velcro mother sticker 211 is fixedly connected to the side of the extension band 23 close to the patient's wound. When the position of the tourniquet body 1 is confirmed, the Velcro sub-sticker 210 can be adhered and connected to the Velcro mother sticker 211, so that the tourniquet body 1 can be limited to the arm or leg to prevent the tourniquet body 1 from shifting during the hemostasis process.

[0029] Reference Figure 4The tourniquet body 1 is provided with a pressing structure 3, which is mainly composed of a hemostatic buckle 31. The hemostatic buckle 31 is fixedly connected to the side of the tourniquet body 1 close to the patient's wound. The hemostatic buckle 31 is placed on the patient's wound, and then the tourniquet body 1 is fixed. The hemostatic buckle 31 can enhance the hemostatic effect. The hemostatic buckle 31 is a cavity. A connecting tube 32 is fixedly connected to the hemostatic buckle 31. One end of the connecting tube 32 is fixedly connected to an air bag 33. The hemostatic buckle 31 is connected to the connecting tube 32, and the connecting tube 32 is connected to the air bag 33. The air bag 33 can be pressed by pressing the air bag 3 3 is used to change the inflation amount in the hemostatic buckle 31, thereby changing the pressure of the hemostatic buckle 31 on the affected part, so as to adjust the pressure of the hemostatic buckle 31 to be moderate, and prevent the pressure from being too high or too low to cause harm to the patient. A clamp 34 is provided on the connecting tube 32, and rubber pads 35 are fixedly connected to the two surfaces of the clamp 34 contacting the connecting tube 32. When the air pressure of the hemostatic buckle 31 is adjusted, the clamp 34 can be clamped on the connecting tube 32 to prevent the air pressure of the hemostatic buckle 31 from being unstable during the hemostasis process. The rubber pad 35 can prevent the clamp 34 from causing damage to the connecting tube 32.

[0030] The working principle is that the tourniquet body 1 is wrapped around the wound to compress the wound and stop bleeding. The rotating column 22 can be rotated to roll the extension belt 23 around the rotating column 22 or pull out the extension belt 23. It can be adjusted according to the thickness of the patient's arm or leg, thereby avoiding the inconvenience caused to the patient due to the fact that the length of the existing bandage tourniquet is uniform and cannot be adjusted. When the position of the rotating column 22 is adjusted, the limiting column 24 can be slid so that the block 26 is inserted into the corresponding slot 27, so that the rotating column 22 is limited to prevent the extension belt 23 from shifting during the hemostasis process. The round block 29 can prevent the limiting column 24 from sliding out of the limit of the tourniquet body 1 when the connecting rod 25 is pulled. When the sliding limiting column 24 makes the block 26 move away from the slot 27, the spring 28 is in a contracted state. Therefore, when the position of the rotating column 22 is adjusted, the connecting rod 25 is released, and the block 26 is in the elastic state. The spring 28 is clamped into the card slot 27 under the action of the rebound elastic force, making the operation more convenient. When the position of the tourniquet body 1 is confirmed, the Velcro sub-stick 210 can be attached to the Velcro mother stick 211, so that the tourniquet body 1 can be limited to the arm or leg to prevent the tourniquet body 1 from shifting during the hemostasis process. The hemostatic buckle 31 is placed on the patient's wound, and then the tourniquet body 1 is fixed. The hemostatic buckle 31 can enhance the hemostatic effect. The inflation amount in the hemostatic buckle 31 can be changed by pressing the airbag 33, thereby changing the pressure of the hemostatic buckle 31 on the affected part, thereby adjusting the pressure of the hemostatic buckle 31 to be moderate to prevent excessive or insufficient pressure from causing harm to the patient. When the air pressure of the hemostatic buckle 31 is adjusted, the clip 34 can be clamped on the connecting tube 32 to prevent the air pressure of the hemostatic buckle 31 from being unstable during the hemostasis process. The rubber pad 35 can prevent the clip 34 from damaging the connecting tube 32.
