Embodiment Construction
[0014] Combine below Figure 1-4 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0015] combined with Figure 1-4 The tourniquet that automatically tightens and relaxes after timing includes a tourniquet ring 14, a tightening rope 47 and a tourniquet ring 14, and the tourniquet ring 14 is provided with a one-way accommodating chamber that opens downward to the left 24. An inner connecting ring 13 is slidably connected to the one-way receiving cavity 24, and a long groove 21 is provided in the inner connecting ring 13, and a first fixing pin 27 is slidably connected to the right part of the long groove 21. A fixed pin 27 is fixedly connected to the tourniquet ring 14, a second fixed pin 26 is slidably connected to the left side of the long groove 21, and a trigger...

The invention discloses a tourniquet capable of automatically tightening and relaxing after timing. The tourniquet comprises a tourniquet ring, a tightening rope and a tourniquet ring, a one-way containing cavity with an opening facing the lower left portion is formed in each tourniquet ring. An inner connecting ring is connected into each one-way accommodating cavity in a sliding manner; a long groove is formed in each inner connecting ring; a first fixing pin is slidably connected into the right side part of each long groove; the first fixing pins are fixedly connected to the tourniquet rings; and the left side part of each long groove is slidably connected with a second fixing pin, and the second fixing pins are fixedly connected with trigger rings. A bidirectional containing cavity with an opening communicating with the upper end and the lower end of each triggering ring is formed in the triggering ring. When the tourniquet is used, the tourniquet can be automatically tightened tostop bleeding only by being pulled out of a bag and sleeve a corresponding part, the smooth appearance structure can ensure that the tourniquet is not hindered when being pulled out, and the injured part can be directly sleeved into the tourniquet without manually opening a circular ring after the tourniquet is pulled out, so that the using operation action of the tourniquet is simplified.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a tourniquet that automatically tightens and relaxes after timing. Background technique [0002] The tourniquet is an important first-aid product. Many non-medical practitioners, such as the military, law enforcement agencies, and outdoor sports enthusiasts, will need to use this product. The use of conventional tourniquets requires certain professional knowledge and operational precision, while the use of hemostatic Most of the tourniquets are used in emergencies. This situation has caused certain difficulties for non-professional medical users. There are also many accidents that miss the opportunity for first aid due to incorrect use of the tourniquet; the tourniquet usually compresses the proximal End blood vessels to achieve hemostasis, so when using the tourniquet, you have to calculate the time and loosen the tourniquet on time to prevent the blood from not flowing.
