[0002] When the human limbs are accidentally injured and the wound bleeds, it is necessary to stop the bleeding in time. The most effective method on the spot is to tie up the arm or leg above the wound, that is, in the direction of the heart, to prevent excessive blood loss. Band-like objects are often used for tying up. If the band-like objects are elastic, the comfort of the injured will be improved, so it is more appropriate to use rubber bands. However, this type of strapping tape still has two defects: First, when there are no other people present, it is difficult for the injured to tie up by themselves, especially when one arm is injured and the other hand is required to operate and bite one end of the strapping tape with the help of teeth, and the process of tying up with force is also painful for the injured; second, the bigger defect is that the tightness of the strapping is difficult to control. If it is loose, it cannot stop bleeding, and if it is tight, it will cause tissue necrosis. Utility Model Content

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] As attached Figure 1 A quick self-rescue tourniquet, comprising a cable tie 1, an air bag 2, a compressed gas cylinder 3 and a valve body 4, as shown in the attached Figure 2 As shown, the cable tie 1 is composed of a long strip body 1-1 and a buckle 1-2 at one end of the strip body 1-1 to form a ring-shaped bundling structure. A nylon buckle 1-3 is fixed to the outer surface of the strip body 1-1. The valve body 4 is glued and fixed to the outer wall of the airbag 2. The airbag 2 is fixed to the cable tie 1. The part of the airbag 2 except the part connected to the valve body 4 is wrapped in the cable tie 1. Figure 3 and Figure 4 As shown in the enlarged view, the valve body 4 is provided with an inflation passage 4-1, an exhaust passage 4-2 and a safety air passage 4-3, the compressed gas cylinder 3 is screwed on the valve body 4 and the bottle mouth is pierced by a puncture needle 4-4 in the valve body 4, the inner cavity of the compressed gas cylinder 3 is communicated with the inner cavity of the airbag 2 through the inflation passage 4-1, the puncture needle 4-4 is a hollow puncture needle, the puncture needle 4-4 is coaxial with the compressed gas cylinder 3, the puncture needle 4-4 has a cone puncture portion 4-4-1 and a hollow portion 4-4-2, and the hollow portion 4-4-2 communicates the inner cavity of the compressed gas cylinder 3 with the inflation passage 4-1;
[0024] The inner cavity of the airbag 2 is also connected to the external atmosphere through the exhaust duct 4-2 and the safety air duct 4-3;
[0025] The valve body 4 is provided with a push-type inflation valve 4-5 for opening and closing the inflation passage 4-1, the valve body 4 is provided with a push-type exhaust valve 4-6 for opening and closing the exhaust passage 4-2, and the valve body 4 is provided with a safety valve 4-7 for opening and closing the safety air passage 4-3. The axial direction of the compressed gas cylinder 3 is in the same direction as the length direction of the cable tie 1, the axial direction of the push-type inflation valve 4-5 is parallel to the outer surface of the belt body 1-1, the axial direction of the push-type exhaust valve 4-6 is parallel to the outer surface of the belt body 1-1, and the axial direction of the safety valve 4-7 is perpendicular to the outer surface of the belt body 1-1;
[0026] like Figure 3 As shown, the button of the push-type inflation valve 4-5 and the button of the push-type exhaust valve 4-6 are staggered outside the two side walls of the valve body 4, that is, the axis of the push-type inflation valve 4-5 and the axis of the push-type exhaust valve 4-6 are staggered, and the staggered setting means that the axes of the two are not on the same straight line, and the buttons of the two are located outside the two opposite side walls of the valve body 4.
[0027] like Figure 3As shown, the structure of the push-type inflation valve 4-5 and the push-type exhaust valve 4-6 is that they have a valve core and a spring, a sealing ring is provided on the valve core, and the two valves are respectively located on the inflation passage 4-1 and the exhaust passage 4-2. When the valve core is pressed, the air passage is penetrated by the annular gap between the smaller diameter section of the valve core and the valve hole between the two sealing rings. When the valve core is released, it is reset under the action of the spring and the air passage is disconnected by the sealing ring. The inflation passage 4-1 and the exhaust passage 4-2 are both composed of segmented air passages that are not on the same axis. Since it is a push-type structure, a first limit pin 4-8 is provided on the valve body 4 to prevent the push-type inflation valve 4-5 from loosening on the valve body 4, and a second limit pin 4-9 is provided on the valve body 4 to prevent the push-type exhaust valve 4-6 from loosening on the valve body 4.
[0028] like Figure 4 As shown, the safety valve 4-7 is an adjustable safety valve with adjustable release air pressure. The pressure on the seal can be adjusted by turning the knob at the outer end. The safety valve 4-7 can also be non-adjustable.
[0029] The shell of the valve body 4 of the utility model is made of nylon material, which has appropriate flexibility and is conducive to sealing. Therefore, the sealing element at the safety valve 4-7 uses a steel ball.
[0030] Generally speaking, the compressed gas cylinder 3 is filled with carbon dioxide gas.
[0031] The simple use process of the utility model is: the tourniquet is as follows: Figure 2 After the form shown is tied on the limb, the initial binding force is formed by the buckle 1-2 and the nylon buckle 1-3, and the push-type inflation valve 4-5 is pressed to inflate and pressurize the airbag 2. After pressurization, if the patient feels it is too tight, the push-type exhaust valve 4-6 is used to properly exhaust the air.
[0032] The safety air pressure value of safety valve 4-7 is the insurance pressure to prevent operating errors.
[0033] The compressed gas cylinder 3 of the utility model can be screwed onto the valve body 4 and punctured in advance when it is needed, and the product can remain in an unpunctured state during storage and transportation stages.
[0034] The tourniquet of the utility model is quick in stopping bleeding, easy to carry, has a long storage period, is convenient for the wounded in the field to quickly save themselves, is safe in use, and is more suitable for use as a war preparedness material.
[0035] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
