Description

Technical Field

[0001] The utility model belongs to the technical field of tourniquets. More specifically, it particularly relates to a tourniquet that is convenient to tighten and fix. Background Art

[0002] A tourniquet is a simple and practical hemostatic tool. The use of a tourniquet can achieve temporary hemostasis and is currently widely used in the emergency treatment of trauma and daily life injuries.

[0003] The utility model with the Chinese patent number CN202320763220.4 proposes a tourniquet, which includes a tightening band, locking teeth, and a self-locking buckle. The tightening band has a fixed end and a free end; the locking teeth are installed on the tightening band and are evenly distributed along the length direction of the tightening band; the self-locking buckle is installed at the fixed end, and there is a channel for passing the tightening band between the self-locking buckle and the fixed end. A fixing space for fixing the limb is formed by enclosing between the fixed end and the free end. The free end passes through the channel to adjust the size of the fixing space, and the self-locking buckle is buckled on the locking teeth so that the free end moves unidirectionally and is fixed to the limb. Therefore, when using this tourniquet, only need to pass the free end through the channel and then pull the free end. The self-locking buckle can be self-locked on the fixed teeth to fix the position of the tightening band, making it more convenient for rescue operations. When removing this tourniquet, it is necessary to push the push block to drive the fixed teeth to rotate away from the locking teeth. When the fixed teeth rotate, the locking teeth will move, thereby driving the further tightening of the tightening band. However, the tourniquet fixed on the patient is already in a tightened state. When the tightening band is further tightened, it may cause the patient to be too tightly bound by the tourniquet, resulting in the patient feeling pain and even causing damage to the patient's limb; and when the tourniquet is already in a tightened state, when the patient pushes the push block, since the patient's arm or leg cannot contract, the fixed teeth cannot rotate, so that the tourniquet cannot be untied. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a tourniquet that is convenient to tighten and fix is provided, in order to achieve a more practical value purpose. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a tourniquet that is convenient to tighten and fix, which is achieved by the following specific technical means:

[0009] Further, an elastic sheet is fixedly installed inside the connection buckle. One side of the elastic sheet abuts against one side of the locking tongue.

[0010] Further, a movable band is movably connected to the outside of the hemostatic bandage. An opening for the adjustment end to pass through is provided inside the movable band. A magic tape one is fixedly connected to the outside of the movable band. An adhesive band is fixedly connected to one side of the movable band. A magic tape two that can cooperate with the magic tape one is fixedly connected to one side of the adhesive band.

[0011] Further, a connection port is provided at one end of the hemostatic bandage. A pull ring is fixedly installed inside the connection port.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. Through the cooperation of the sliding key and the connecting rod, the present utility model can drive the flexible movement of the sliding seat. Through the cooperation of the sliding seat, the rotating shaft, and the locking tongue, the flexible up and down movement of the locking tongue can be driven, so that the locking tongue can be driven to leave the fixed teeth without rotating the locking tongue, thereby realizing the flexible disassembly of the hemostatic bandage.

[0014] 2. Through the cooperation of the spring and the connecting rod, the present utility model can limit the sliding seat when it is necessary to fix the fixed teeth, thereby limiting the locking tongue and avoiding the loosening of the hemostatic bandage caused by the accidental unlocking of the locking tongue when fixing the fixed teeth.

The tourniquet 1 is divided into an adjustment end 101, a movable end 102 and a fixed end 103. A connection buckle 2 is fixedly installed on the outer side of the fixed end 103. A sliding seat 3 is installed inside the connection buckle 2. Connecting rods 7 are fixedly installed on both sides of the sliding seat 3. Connection grooves 10 corresponding to the connecting rods 7 are provided on both sides of the connection buckle 2. The connection grooves 10 are slidably connected with the connecting rods 7. A spring 8 is fixedly installed on the top side of the inner wall of the connection groove 10. One end of the spring 8 is fixedly connected with the top side of the connecting rod 7; A locking mechanism is installed on the bottom side of the sliding seat 3.

[0027] One end of the connecting rod 7 passes through the connection groove 10 and is fixedly installed with a sliding key 9, which is convenient for the user to drive the connecting rod 7 to move when disassembling the tourniquet 1.

[0028] A plurality of groups of fixed teeth 6 are fixedly installed at equal intervals on one side of the adjustment end 101. A first inclined surface is provided on one side of the plurality of groups of fixed teeth 6. When tightening the tourniquet 1, it is ensured that the fixed teeth 6 can pass through the lock tongue 5.

[0029] The locking mechanism includes a lock tongue 5. The lock tongue 5 is rotatably connected with the sliding seat 3 through a rotating shaft 4. A second inclined surface is provided on one side of the lock tongue 5. The second inclined surface is parallel to the first inclined surface and can be mutually limited and attached. So that when the user tightens the tourniquet 1, the lock tongue 5 can be driven to quickly move upward by squeezing the second inclined surface with the first inclined surface, making it more labor-saving for the user to tighten the tourniquet 1.

[0030] A spring piece 14 is fixedly installed inside the connection buckle 2. One side of the spring piece 14 abuts against one side of the lock tongue 5, which can realize that after the lock tongue 5 rotates, the lock tongue 5 is automatically reset.

[0031] An activity band 11 is movably connected to the outer side of the tourniquet 1. An opening for the adjustment end 101 to pass through is provided inside the activity band 11. A first magic tape is fixedly connected to the outer side of the activity band 11. An adhesive tape 12 is fixedly connected to one side of the activity band 11. A second magic tape which can cooperate with the first magic tape is fixedly connected to one side of the adhesive tape 12, which is convenient for fixing one end of the tourniquet 1.

[0032] A connection port is provided at one end of the tourniquet 1. A pull ring 13 is fixedly installed inside the connection port, which is convenient for the user to tighten the tourniquet 1 and increases the convenience of the product.

[0033] Working principle of this embodiment: When it is necessary to disassemble the tourniquet 1, first slide the sliding key 9 upward to drive the connecting rod 7 to move. When the connecting rod 7 moves upward, the sliding seat 3 and the locking tongue 5 move upward, so as to drive the locking tongue 5 away from the fixed teeth 6, and pull the movable end 102 to drive the adjusting end 101 and the fixed teeth 6 away from the inner side of the connecting buckle 2, completing the disassembly of the tourniquet 1.

[0034] Finally, it should be noted that the tourniquet 1 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art.
