Description

Technical field

[0001] The invention relates to a tourniquet that can be quickly applied and removed, in particular a structure of a tourniquet which structure enables quick application and removal of the tourniquet. State of the art

[0002] In the case of injuries, in addition to immediate wound treatment, immediate hemostasis is essential, especially for large and deep wounds, to prevent excessive bleeding and potentially life-threatening conditions. A common method currently used is to wrap a bandage or elastic wrap around the affected limb, thereby blocking arterial blood flow through the pressure exerted by the bandage and achieving hemostasis. However, because bandages and elastic wraps are applied by hand, the pressure they exert is limited, and optimal hemostasis cannot always be achieved. To avoid ischemia and necrosis of the distal tissue caused by prolonged wrapping, the pressure must be temporarily released after a certain period before re-wrapping.However, since bandages or elastic wraps have to be wrapped in several layers to achieve the desired compression, releasing the compression is time-consuming. Object of the invention

[0003] The invention is based on the objective of creating a tourniquet that can be quickly applied and removed, thereby eliminating the shortcomings mentioned in the prior art. Technical solution

[0004] The problem is solved according to the invention by a tourniquet that can be quickly applied and removed, having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0005] The invention provides a quickly applied and removed tourniquet consisting of a bandage and a ratchet. A distal end of the bandage is passed through a buckle at the other end, turned inside out, and then glued to the bandage so that the bandage is wrapped around the entire extremity where bleeding needs to be stopped. Subsequently, an upper cover of the ratchet is repeatedly pressed so that the ratchet gradually tightens the entire bandage. This achieves hemostasis of the extremity.

[0006] According to the invention, a hook and loop fastener is arranged on the surface of the bandage.

[0007] According to the invention, the ratchet comprises a stopper having a front projection onto which an elastic element is placed.

[0008] According to the invention, the ratchet comprises a trigger having a front projection onto which an elastic element is placed.

[0009] The following section explains the tasks, features, and advantages of the present invention with reference to a detailed description of an exemplary embodiment and the accompanying drawing. The invention is not intended to be limited to the description and the accompanying drawing.

[0010] As in Fig. 1 to Fig. As shown in section 6, the tourniquet 1 according to the invention, which can be quickly applied and removed, comprises the following: a bandage 2, at one end of which a buckle 21 is arranged and on the upper surface of which a drawstring cord 22 and a fixed cord 23 are arranged; and a ratchet 3, which is attached to the strap 2 and comprises the following: a lower part 31 comprising a pin 311, two corresponding guide slots 312, a guide opening 313, two corresponding aligned openings 314, two corresponding support parts 315 and two corresponding notches 316, wherein the pin 311 is to be connected to the fixed cord 23 of the band 2; a connecting element 32 which is inserted simultaneously through the two corresponding aligned openings 314, wherein two corresponding gears 321 are arranged on the outer sides of the connecting element 32, wherein the connecting element 32 is connected to the drawstring cord 22 of the bandage 2; a stopper 33 which is inserted into the two corresponding guide slots 312 of the lower part 31, wherein the stopper 33 has a front projection 331 which is inserted into the guide opening 313 of the lower part 31, wherein the stopper 33 is supported on the gears 321 of the connecting element 32; an upper cover 34 having two corresponding aligned openings 341, two corresponding guide slots 342 and a guide hole 343, wherein the corresponding aligned openings 341 correspond to the two corresponding aligned openings 314, wherein the connecting element 32 further simultaneously inserted through the two corresponding aligned openings 341 of the upper cover 34 in such a way that the upper cover 34 can be connected to the lower part 31 and rotated back and forth; and a trigger 35 which is installed in the two corresponding guide slots 342 of the upper cover 34, wherein the trigger 35 has a front projection 351 which is inserted into the guide hole 343 of the upper cover 34, wherein the trigger 35 is supported on the gears 321 of the connecting element 32.

[0011] A Velcro fastener is arranged on the surface of bandage 2.

[0012] An elastic element 332 is placed on the front projection 331 of the stopper 33.

[0013] An elastic element 352 is placed on the front projection 351 of the trigger 35.

[0014] According to the invention, to insert the tourniquet 1, a distal end of the bandage 2 is passed through the buckle 21 at the other end of the bandage 2, turned over, and then firmly adhered to the bandage 2 so that the bandage 2 is wrapped around the entire extremity where bleeding needs to be stopped. Subsequently, the upper cover 34 of the ratchet 3 is repeatedly pressed so that the ratchet 3 gradually tightens the entire bandage 2. This achieves hemostasis of the extremity.

[0015] When the upper cover 34 of the ratchet 3 is continuously pressed, the trigger 35 presses firmly against the gears 321 of the connecting element 32. Continuous pressure on the upper cover 34 also causes the connecting element 32 to rotate. Once the connecting element 32 is rotating, the drawstring 22 of the bandage 2 is pulled tighter, causing the entire bandage 2 to tighten. To prevent the connecting element 32 from rotating in the opposite direction and loosening the bandage 2, and to maintain the tightened state of the bandage, the stopper 33 is brought to rest against the gears 321 of the connecting element 32.

[0016] When it is no longer necessary to stop the bleeding, the trigger 35 is first pushed upwards to release it from the gears 321 of the connecting element 32. Simultaneously, the upper cover is rotated to its maximum angle, so that the stopper also releases from the gears 321 of the connecting element 32. If the gears 321 of the connecting element 32 are not pressed by the trigger 35 and the connecting element 32, the connecting element can rotate in the opposite direction to release the drawstring 22, thereby loosening the entire bandage 2.

[0017] The tourniquet 1 according to the invention, which can be applied and removed, differs from conventional bandages or elastic bandages in that it consists of a bandage 2 and a ratchet 3. The bandage 2 can be quickly tightened by continuously pressing the upper cover 34 of the ratchet 3 to achieve hemostasis. Furthermore, the tightened state of the bandage 2 can be quickly released by pushing the trigger 35 of the ratchet 3 upwards. In this way, the tourniquet 1 according to the invention can be quickly applied and removed, contributing to efficient hemostasis. Due to the special design for quickly tightening and loosening the tourniquet 1, the intensity of hemostasis can also be adjusted at any time.

[0018] Although the present invention has been described in detail with reference to an exemplary embodiment, it is obvious to those skilled in the art that the invention is not limited to this embodiment, but rather that modifications are possible such that individual features can be omitted or different combinations of features can be implemented, as long as the scope of protection of the appended claims is not exceeded. The disclosure of the present invention includes all combinations of the individual features presented.
