Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to an automatically releasable tourniquet. Background Art

[0002] The tourniquet is made of natural rubber or special rubber, a medical polymer material, and is long and flat with strong elasticity. It is suitable for one-time use in medical institutions for infusion, blood drawing, blood transfusion, and hemostasis during routine treatment and rescue; or for emergency hemostasis in case of limb bleeding or snake and insect bite bleeding in the wild.

[0003] Tourniquet hemostasis is a simple and effective method of hemostasis used in first aid for severe bleeding in the limbs. It achieves the purpose of hemostasis by compressing blood vessels and blocking blood flow.

[0004] If the tourniquet is used improperly or for too long, it can cause ischemia and necrosis of the distal limbs, resulting in disability. It is especially suitable for elderly people and infants with impaired cognition to avoid adverse events caused by forgetting to loosen the tourniquet. Based on the above problems, we provide a tourniquet that can be automatically released.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a tourniquet that can be automatically released.

[0007] The utility model provides an automatically releasable tourniquet adopts the following technical solution:

[0008] A tourniquet that can be automatically released comprises a shell; a tourniquet arranged on one side of the shell, with Velcro sewn on both the front and back sides of the tourniquet; a sleeve arranged on the other side of the shell; an adjustment mechanism arranged in the shell and used for contracting and tightening the tourniquet; and a timing mechanism arranged on the shell and used for unlocking the adjustment mechanism.

[0009] Preferably, the adjustment mechanism comprises a rotating shaft rotatably connected in the shell, a drawstring is sewn on the side of the rotating shaft, a side end of the drawstring is sewn and connected to the tourniquet, and the drawstring can pull the tourniquet to move and contract.

[0010] Preferably, a rotating disk is fixedly connected to the top end of the rotating shaft.

[0011] Preferably, the outer side surface of the turntable is provided with tooth grooves.

[0012] Preferably, the timing mechanism includes an inverted U-shaped rod slidably inserted on the top of the turntable, the bottom ends of the inverted U-shaped rod are arranged below the turntable, and a plurality of limiting grooves are opened on the top of the shell, and the bottom ends of the inverted U-shaped rod can be inserted into the corresponding limiting grooves.

[0013] Preferably, two limiting rods are fixedly connected to the top of the turntable, and the inverted U-shaped rod is slidably connected to the two limiting rods.

[0014] Preferably, a timer is fixedly mounted on the top of the turntable, an electromagnet is mounted on the top of the turntable, a magnet is fixedly connected to the middle of the inverted U-shaped rod, the timer is electrically connected to the electromagnet, and the magnet has the same magnetic pole as the electromagnet.

[0015] Preferably, the outer edges of the tourniquet are rounded.

[0016] In summary, the utility model includes the following beneficial technical effects:

[0017] The tourniquet is wrapped around the area where hemostasis is required, and then the tourniquet is passed through the sleeve, and the tourniquet is pasted and fixed by the Velcro on the tourniquet. Then, the turntable is rotated, and the turntable drives the shaft to rotate, so that the shaft tightens the drawstring, thereby tightening the entire tourniquet and squeezing the hemostasis area. Then, the inverted U-shaped rod is pushed downward, so that the two bottom ends of the inverted U-shaped rod are inserted into the corresponding limiting grooves, thereby completing the limit of the position of the turntable. Then, the medical staff can set the time through the timer. After the timer expires, the circuit of the electromagnet will be connected, so that the electromagnet is energized with the opposite magnetic pole of the magnet, thereby pushing the inverted U-shaped rod upward, so that the inverted U-shaped rod is separated from the limiting groove. At this time, the tightened tourniquet will be loosened under the action of the rebound force, thereby loosening the binding of the hemostasis area. Through this structural design, the automatic loosening function of the tourniquet is realized, the tedious manual operation is abandoned, and the ability to set the working time is given. This design not only enhances the flexibility of the tourniquet, but also significantly improves its safety and convenience in use.
