Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a tourniquet. Background Art

[0002] A tourniquet is a medical device used to stop bleeding. The principle of a tourniquet is to compress blood vessels by tightening the limbs, reduce the diameter of the blood vessels, and block the blood flow in the blood vessels, thereby preventing blood from flowing out of the wound.

[0003] When a traditional tourniquet is used, after initially tightening the bleeding limb, the tightness of the tourniquet on the limb may not be enough and needs to be tightened. However, most existing tourniquets are not easy to tighten, which affects their use. Utility Model Content

[0004] The utility model provides a tourniquet which can be tightened after being initially tightened.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A tourniquet comprises a main belt and a loop installed at one end of the main belt, a Velcro hook surface is fixed on the belt surface at the other end of the main belt, and a Velcro fur surface is fixed on the Velcro hook surface along the main belt toward the loop. When in use, the Velcro hook surface passes through the loop and adheres to the Velcro fur surface, so that the main belt is tightly tied to the limb in an annular shape, and a fine-adjustment mechanism is provided on the main belt between the Velcro fur surface and the loop, which is used to tighten the main belt tied to the limb.

[0007] Furthermore, the fine-tuning mechanism includes two transverse axes fixed on the main belt, an auxiliary belt is connected between the two transverse axes, an adjustment tube runs through the middle of the auxiliary belt, and the auxiliary belt is twisted by rotating the adjustment tube laterally.

[0008] Furthermore, a telescopic rod is provided in the adjusting tube for damping sliding.

[0009] Furthermore, a ring belt is provided on the main belt for sleeve-limiting one end of the telescopic rod.

[0010] Furthermore, a block is provided at one end of the telescopic rod.

[0011] Furthermore, a limit block is provided at the end of the telescopic rod away from the escape block.

[0012] Furthermore, the buoyancy block is a circular plate.

[0013] Furthermore, the diameter of the circular plate is larger than the outer diameter of the regulating tube.

[0014] Furthermore, the main belt is arrow-shaped away from the end of the ring.

[0015] Furthermore, the ring is a rectangular ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Combine the following Figure 1-3 Description of a tourniquet:

[0023] A tourniquet comprises a main belt 1 and a loop 2 installed at one end of the main belt 1, a Velcro hook surface 4 is fixed on the belt surface of the other end of the main belt 1, and a Velcro fleece surface 3 is fixed on the Velcro hook surface 4 along the main belt 1 toward the loop 2. When in use, the Velcro hook surface 4 passes through the loop 2 and adheres to the Velcro fleece surface 3, so that the main belt 1 is tied tightly to the limb in a ring shape, and a fine-adjustment mechanism is provided on the main belt 1 between the Velcro fleece surface 3 and the loop 2, which is used to tighten the main belt 1 tied to the limb.

[0024] When in use, fit the other side of the tourniquet's Velcro hook surface 4 to the limb, then pass the end of the main belt 1 through the loop 2 to make the main belt 1 form a ring, and then tighten the Velcro hook surface 4 to fit the Velcro fleece surface 3 to complete the initial hemostatic binding and fixation of the tourniquet.

[0025] like Figure 1-3 As shown:

[0026] The fine-tuning mechanism includes two transverse shafts 5 fixed on the main belt 1, an auxiliary belt 6 is connected between the two transverse shafts 5, an adjustment tube 7 runs through the middle of the auxiliary belt 6, and the auxiliary belt 6 is twisted by rotating the adjustment tube 7 laterally.

[0027] When the tourniquet needs to be tightened, the auxiliary belt 6 is twisted by rotating the adjustment tube 7, and then the two horizontal axes 5 are pulled closer, so that the main belt 1 between the two horizontal axes 5 is gathered, thereby achieving the purpose of tightening the main belt 1 tied around the limb.

[0028] Further:

[0029] In order to facilitate the rotation of the adjusting tube 7 and twist the auxiliary belt 6, a telescopic rod 8 is provided through damping sliding in the adjusting tube 7. The telescopic rod 8 is pulled out of the adjusting tube 7 to lengthen the overall length of the telescopic rod 8 and the adjusting tube 7. Thus, according to the lever principle, the adjusting tube 7 can be driven by the telescopic rod 8 to twist the auxiliary belt 6.

[0030] Further:

[0031] In order to fix the auxiliary belt 6 after being twisted, a ring belt 9 is provided on the main belt 1. After the auxiliary belt 6 is twisted to achieve the required tightness of the main belt 1 on the limbs, the telescopic rod 8 is inserted into the ring belt 9 away from the end of the adjusting tube 7 to limit one end of the telescopic rod 8 to prevent the auxiliary belt 6 from rotating.

[0032] Further:

[0033] By providing a block at one end of the telescopic rod 8, it is convenient for the annular belt 9 to limit the telescopic rod 8 through the block. At the same time, by setting the block as a circular plate, and the diameter of the circular plate is larger than the outer diameter of the adjusting tube 7, it is convenient to pull the telescopic rod 8 out of the adjusting tube 7 through the block.

[0034] Further:

[0035] A limit block is provided at the end of the telescopic rod 8 away from the emitting block, and a limit edge is provided inside the end of the adjusting tube 7 close to the emitting block, so as to prevent the telescopic rod 8 and the adjusting tube 7 from being separated.

[0036] Further:

[0037] By setting the end of the main belt 1 away from the ring 2 to be arrow-shaped, it is convenient to insert the arrow-shaped end into the ring 2; and by setting the ring 2 to be a rectangular ring, it is further convenient to insert the arrow-shaped end into the ring 2.

[0038] Of course, the above description is not a limitation of the instructions for use, and the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the utility model also fall within the protection scope of the utility model.
