Novel tourniquet

Abstract

To provide a tourniquet with which a women can readily stop bleeding by herself.SOLUTION: A tourniquet is manufactured by applying an adhesive to the whole area or part of a rear face of a fabric that includes ridges in a longitudinal direction having elongation of 1.1 to 3 times.SELECTED DRAWING: None

Description

[Technical Field]

[0001] To provide a tourniquet for use when completely stopping bleeding after amputation of an arm, leg, etc., or when stopping the flow of blood after a poisonous snake bite, and particularly to a product for improving ease of use and work efficiency. [Background technology]

[0002] Conventional tourniquets, used when you want to completely stop bleeding or stem the flow of blood, such as when an arm is amputated, have been made from woven rubber, synthetic rubber, or natural rubber, and have only been available in thicknesses of 1 to 2 mm, widths of 2 to 10 cm, and lengths of 1 to 6 m. Summary of the Invention [Problem to be solved by the invention]

[0003] In conventional technology, when completely stopping bleeding or stemming the flow of blood, such as after an amputation, a tourniquet is wrapped around the arm or other area, pulling as hard as possible with a strong force. However, it is difficult to wrap tightly enough to achieve the required pressure to stop the bleeding. Furthermore, the initial wrapping tends to shift, making it difficult to wrap properly. Furthermore, because the surface is flat, it can slip and shift over time, resulting in loosening. Furthermore, because the width is approximately 2cm to 10cm, the large area disperses the pressure, requiring very strong wrapping force. Therefore, it is extremely difficult for a single woman to wrap the tourniquet tight enough to achieve the required pressure, requiring multiple people to do the work. Furthermore, when the tourniquet is tied or taped to secure it, it often loosens during this process. [Means for solving the problem]

[0009] The tourniquet of the present invention uses a stretchable fabric with ridges in the longitudinal direction, and has an adhesive applied to the entire or part of the back surface. [Effects of the Invention]

[0017] The adhesive helps the beginning of the roll stick, eliminating the problem of difficulty in rolling at the beginning. The adhesive also eliminates the problem of the bandage shifting over time. Furthermore, the ridges narrow the bandage by 20 to 70 percent when pulled by hand, increasing the pressure and making it easier to stop bleeding. A product has been created that even a woman can use to easily stop bleeding. DETAILED DESCRIPTION OF THE INVENTION

[0019] Examples of the present invention are given below. Two examples of stretchable, longitudinally ribbed Russell knit fabric weaves are shown below. The typical structures are shown below, but this is not the only way as long as ridges can be formed. Also, L1 and L2, and L3 and L4 can be interchanged. Example 1 ● L1(1 IN 1 OUT):20·46·20·46·42·46 ● L2(1 IN 1 OUT):46·20·46·20·24·20 ● L3(1 IN 1 OUT):22·00 ● L4(1 IN 1 OUT):00·22 Example 2 ● L1(1 IN 1 OUT):20·46·20·24 ● L2(1 IN 1 OUT):46·20·46·42 ● L3(1 IN 1 OUT):22·00 ● L4(1 IN 1 OUT):00·22 For L1 and L2, synthetic filament yarns such as nylon and polyester are used. The thickness is preferably 50dtex to 600dtex. For L3 and L4, elastic yarns such as polyurethane, synthetic rubber, or natural rubber are used. The thickness is 70dtex to 900dtex. The elongation of the finished fabric is preferably 1.05 to 3 times. The runner will vary depending on the type and thickness of the thread used, so I will write an example. In the case of Example 1, the fabric created in this experiment is L1 and L2 are made of nylon thread 155dtex and the runner is 158cm L3 and L4 are made of polyurethane thread 620dtex with a 13cm runner. So I created it. However, the conditions for setting the runner are that it is possible to knit the fabric, and the number can be anything as long as the finished fabric stretches 1.1 to 3 times its original length. Apply adhesive to the entire backside of the fabric or to part of it, and cut it into pieces 1cm to 20cm wide and 0.5m to 10m long. To prevent the adhesive from drying out, apply release paper to the adhesive surface or roll it up to complete the process.

Claims

[Claim 1] A tourniquet having a thickness of 0.5 mm to 2 mm, a width of 1 cm to 20 cm and a length of 0.5 m to 10 m, which is made of a fabric with ridges in the length direction and an elongation of 1.1 to 3 times, with an adhesive applied to the entire or part of the back surface.
