[0002] When the injured person has an open wound accompanied by bleeding, first aid devices are generally needed to stop the bleeding. General first aid devices are hemostatic bandages such as Band-Aids and cotton gauze. If the wound involves rupture of a large blood vessel artery and the bleeding is large and rapid, it is not enough to rely solely on hemostatic cotton pads. Mechanical compression bandages must also be used to meet the needs of first aid and hemostasis.
[0003] The existing hemostatic devices usually use bandages or straps to fix and tighten, so as to achieve compression on the wound. However, this type of fixed and tightened compression force applies force over a wide area, usually applying pressure to the entire limb of the patient. The compressive pressure range is relatively scattered, and it is not possible to simply apply pressure to a single point on the wound, resulting in the problem of prolonged hemostasis time. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-3 As shown, a linkage type trauma tourniquet comprises a base 1 and a hemostatic cotton cloth 2. The hemostatic cotton cloth 2 is connected to the surface of the base 1;
[0026] A slide groove 3 is provided in the inner cavity of the side wall of one side of the base 1, and a sliding member 4 is slidably connected to the inner cavity of the slide groove 3, one end of the sliding member 4 is connected to a first bandage 5, and the other end of the sliding member 4 is connected to an air bag 8, and a second bandage 6 that cooperates with the first bandage 5 is fixedly connected to the other side wall of the base 1, so that the base 1 is fixedly attached to the wound in a ring shape;
[0027] The surface of the base 1 is provided with a mounting groove 7, the inner cavity of the mounting groove 7 is provided with an extrusion bag 9, the extrusion bag 9 is connected with the air bag 8 through a pipe 10, and the surface of the extrusion bag 9 can be attached to the hemostatic cotton cloth 2;
[0028] The first bandage 5 can be tightened on the second bandage 6 so that the base 1 fits tightly on the injured person's limb. During the tightening of the first bandage 5, the first bandage 5 can drive the sliding part 4 to squeeze the airbag 8 and inflate the squeezing bag 9 through the pipe 10, so that the hemostatic cotton cloth 2 is pressed and fits the wound.
[0029] The device can not only fix the hemostatic cotton cloth on the injured person's limb through the cooperation of the first bandage and the second bandage, but also, during the tightening of the first bandage, the first bandage can serve as a power source for driving the hemostatic cotton cloth to be squeezed downward, that is, during the tightening of the first bandage, the hemostatic cotton cloth can automatically bulge up and fit the wound, and during the unfolding of the first bandage, the hemostatic cotton cloth can automatically retract and move away from the wound.
[0030] Among them, Figure 1 As shown, a plurality of mounting holes 11 are provided on the surface of the first bandage 5, and a socket 12 which cooperates with the mounting hole 11 is connected to the end of the second bandage 6 away from the base 1, and a plug-in structure similar to that of a watch strap is formed between the socket 12 and the mounting hole 11, so that the operator can fix the base 1 with one hand and tighten the base 1 on the patient's limb.
[0031] Specifically, Figure 2-4 As shown, the sliding member 4 includes a fixed seat 41 and an I-shaped sliding seat 42, the fixed seat 41 is fixedly connected to the inner cavity of the slide groove 3, and the I-shaped sliding seat 42 is slidably inserted on the fixed seat 41;
[0032] The end of the I-shaped sliding seat 42 located on one side of the fixing seat 41 is connected to the first bandage 5 , and the end of the I-shaped sliding seat 42 located on the other side of the fixing seat 41 is connected to the uniform extrusion bag 9 on the side wall of the fixing seat 41 .
[0033] When the first bandage 5 is tightened, the first bandage 5 moves toward the opening of the slide groove 3, and the moving first bandage 5 drives the type sliding seat 42 to slide along the fixed seat 41. As the type sliding seat 42 gradually moves outward, the moving type sliding seat 42 can gradually approach the fixed seat 41, and squeeze the airbag 8 in the process of approaching. The volume of the airbag 8 after squeezing gradually decreases, and the gas in the inner cavity is compressed and gradually enters the squeezing bag 9 through the pipe 10. At this time, the squeezing bag 9 begins to expand, and the expanded squeezing bag 9 bulges outward and squeezes the hemostatic cotton cloth 2, so that the hemostatic cotton cloth 2 is squeezed and fits the wound to stop bleeding.
[0034] Further, such as Figure 3 and Figure 5 As shown, a through hole 14 is provided at the center of the airbag 8 for the middle vertical section of the I-shaped sliding seat 42 to pass through, so as to facilitate the installation of the I-shaped sliding seat 42 .
[0035] Since the volume of the airbag 8 shrinks after being squeezed, when hemostasis is successful, the first bandage 5 and the second bandage 6 need to be unlocked so that the base 1 can be removed from the patient's limb. At this time, the inflated squeezing bag 9 needs to be restored to its original state for reuse next time.
[0036] Specifically, Figure 3-4 As shown, a return spring 13 is connected between the end of the I-shaped sliding seat 42 away from the first bandage 5 and the inner cavity side wall of the slide groove 3, so that the I-shaped sliding seat 42 can be automatically unfolded.
[0037] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
