[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0029] like Figures 1 to 4 As shown, an embodiment of the utility model provides a spin-type tourniquet, comprising: a self-adhesive tape 1, the self-adhesive tape 1 is configured as a double-layer tape body, one layer of the tape body is configured as a flexible material, and the other layer of the tape body is configured as a Velcro material, and the cross-section of one side of the self-adhesive tape 1 is semicircular, the other side of the self-adhesive tape 1 is fixedly connected with a hard mounting tape 6, the side of the hard mounting tape 6 away from the self-adhesive tape 1 is in a buckle shape, a tightening tape 2, one side of the tightening tape 2 passes through the buckle of the hard mounting tape 6 and is fixedly connected to the self-adhesive tape 1, the side of the tightening tape 2 away from the hard mounting tape 2 is movably connected with a buckle ring 3, and an anti-slip component is arranged on the side of the self-adhesive tape 1 away from the tightening tape 2.

[0030] The working principle and beneficial effects of the above technical scheme are as follows: first, take out the rotary tourniquet and put it into the right hand, hold it in the palm of your hand, bite the tail end of the self-adhesive tape 1 with your teeth, and use the right hand and teeth to simultaneously unfold the tourniquet into a circle until the anti-slip part in the self-adhesive tape 1 is against the buckle ring 3, then put the tourniquet on the upper 1 / 3 of the left upper arm, with the buckle ring 3 facing the inside of the limb, tighten the self-adhesive tape 1 with your right hand, and tighten it in the opposite direction. This embodiment adopts technical means of cooperating with the anti-slip part and the self-adhesive tape 1. The anti-slip part can effectively prevent the self-adhesive tape 1 from falling out of the buckle ring 3 during the use of the tourniquet, thereby overcoming the shortcomings of the prior art and achieving the technical effect of shortening the hemostasis time.

[0031] In one embodiment, the anti-dropping member is configured as a hose 4 , and the hose 4 is embedded between the double-layer tape bodies of the self-adhesive tape 1 .

[0032] The working principle and beneficial effects of the above technical solution are as follows: the hose 4 can be directly cut from an idle medical hose and sewn into the self-adhesive tape 1. The hose 4 made of flexible material can fit the skin of the injured person well to avoid pressure damage to the injured person, while greatly reducing the production cost. It should be noted that the anti-slip component includes but is not limited to the hose 4, and other materials that can achieve the same effect can be selected.

[0033] In one embodiment, the hose 4 is arranged on the side of the self-adhesive tape 1 where no Velcro is provided, and is located 2 to 6 cm away from the end of the self-adhesive tape.

[0034] The working principle and beneficial effects of the above technical solution are as follows: by arranging the hose 4 at this position, it can prevent the self-adhesive tape 1 from falling out of the buckle ring 3 when the left hand stretches the tourniquet into a circle, and at the same time, a 2 to 6 cm length of the self-adhesive tape 1 is reserved for the user to quickly tighten it with his fingers, which is more reasonable.

[0035] In a specific embodiment, the hose 4 is located 4 cm away from the end of the self-adhesive tape.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the hose 4 is appropriately arranged at a position 4 cm away from the end of the self-adhesive tape, ensuring that when the tourniquet is stretched into a ring shape, the length of the self-adhesive tape 1 remaining on the other side of the buckle ring 3 is about 4 cm, so that the user can quickly pinch the self-adhesive tape 1 on that side with his fingers and tighten it.

[0037] In a specific embodiment: the length of the self-adhesive tape 1 is set to 50 to 70 cm, and the length of the tightening tape 2 between the buckle ring 3 and the hard installation tape 6 is set to 4 to 6 cm.

[0038] The working principle and beneficial effects of the above technical solution are as follows: the existing self-adhesive tape 1 is relatively short, about 50 cm. If the self-adhesive tape 1 is tightened with too much force, it is easy to cause the self-adhesive tape 1 to slip out of the hand and need to be tightened again, wasting rescue time. Therefore, the length of the self-adhesive tape 1 can be set between 50 and 70 cm to meet the needs of medical staff with different styles. Similarly, the length of the existing tightening tape 2 is set between 4 and 6 cm. When tightened, the length of the tightening tape 2 between the buckle ring 3 and the hard mounting tape 6 should not be too short, otherwise the skin may be pinched during tightening. The length of the tightening tape 2 can be appropriately increased to reduce the probability of this situation. It should not be too long, otherwise the time for tightening the wand 9 will be excessively increased. A length between 4 and 6 cm is more appropriate.

[0039] In a specific embodiment: the length of the self-adhesive tape 1 is set to 65 cm, and the length of the tightening tape 2 between the buckle ring 3 and the hard mounting tape 6 is set to 4 cm.

[0040] The working principle and beneficial effects of the above technical solution are as follows: the length of the self-adhesive tape 1 is set to 65 cm, which is more convenient to use and can reduce the probability of slipping out of the hands; the length of the tightening tape 2 located between the buckle ring 3 and the hard mounting tape 6 is 4 cm, which is more appropriate, which can not only reduce the probability of pinching the skin, but also control the time of tightening the twist rod 9 within a shorter range, which is more practical.

[0041] In one embodiment: a flexible pad 5 is provided on the belt body of the tightening belt 2 between the buckle ring 3 and the hard mounting belt 6, and two sides of the flexible pad 5 are fixedly connected to the buckle ring 3 or the hard mounting belt 6 respectively.

[0042] The working principle and beneficial effects of the above technical solution are as follows: when the twist rod 9 is tightened, the distance between the buckle ring 2 and the hard mounting belt 6 gradually becomes smaller, which can easily pinch the patient's skin at that position. The flexible pad 5 can protect the skin at that position, reduce the probability of being pinched, and further improve the practicality of the device.

[0043] In one embodiment: a fixing clip 7 is fixedly connected to one side of the hard mounting belt 6 close to the self-adhesive belt 1, a secondary belt 8 is provided on the tightening belt 2, one side of the secondary belt 8 passes through the buckle of the hard mounting belt 6 and is fixedly connected to the corresponding side of the tightening belt 2, the other side of the secondary belt 8 is fixedly connected to the other side of the tightening belt 2, and a twist rod 9 is fixedly connected to the middle section of the belt body of the secondary belt 8.

[0044] The working principle and beneficial effects of the above technical solution are as follows: after the tourniquet is tied, the twist rod 9 can be further rotated to make the two sides of the auxiliary belt 8 approach each other, and the tightening belt 2 can be further tightened to tighten the entire tourniquet, which is more labor-saving and faster than directly tightening the tourniquet. Then one end of the twist rod 9 can be inserted into the fixing clip 7 and locked.

[0045] In one embodiment, the outer side of the fixing clip 7 is covered with Velcro, and one side of the fixing clip 7 is fixedly connected with a fixing belt 10 .

[0046] The working principle and beneficial effects of the above technical solution are: the end of the fixing belt 10 that is not connected to the fixing clip 7 is glued together with the Velcro on the fixing clip 7 to seal the gap of the fixing clip 7, which can prevent the twist rod 9 from escaping from the gap. At the same time, the time for applying hemostasis can be written on the fixing belt 10 for subsequent reference, so as to facilitate the judgment of the time to remove the tourniquet based on the time.

[0047] In one embodiment, a red scratch mark 11 is coated on the semicircular end of the self-adhesive tape 1 .

[0048] The working principle and beneficial effects of the above technical solution are as follows: the setting of the red wound mark 11 makes it convenient for medical personnel or the injured person using the tourniquet to quickly find the end of the self-adhesive tape 1 and pass it through the corresponding buckle ring 3, thereby improving the hemostasis speed.

[0049] Working principle and usage process:

[0050] The working principle of this product will be adjusted accordingly according to different bleeding sites.
