[0002] In hospitals, after doctors perform coronary angiography, cerebral angiography or interventional treatment via radial or ulnar arteries, they need to stop bleeding at the puncture site of the radial or ulnar artery. Currently, the most popular method is to compress the puncture point with a column and then wrap it with an elastic bandage for pressure bandage.

[0003] While the above-mentioned wrist pressure bandage stops bleeding, the plastic columnar object presses on the puncture point, which is relatively hard in texture. The pressure of the pressure bandage is relatively large, causing varying degrees of severe obstruction of venous return in the hand, swelling of the hand, obvious pain, and even rupture of capillaries in the palm, causing varying degrees of complications. The swelling of the hand is mainly caused by the partial blocking of venous return by the hemostatic bandage. The wrist pressure bandage hemostasis method will cause swelling of the patient's hand. When the patient's radial artery or ulnar artery puncture site is hemostatically bandaged, there is a problem that there is no design with soft pressure on the puncture site. For this reason, the present application proposes an anti-swelling wrist compression hemostat. Utility Model Content

[0004] The utility model aims to provide an anti-swelling wrist compression hemostat to solve the problem of the lack of a soft design for compressing the puncture site when applying pressure bandage to stop bleeding on the wrist proposed in the above background technology.

The outer side of the end of the radial and ulnar artery compression column 4 is sleeved with an anti-loosening rubber ring 6. The radial and ulnar artery compression column 4 compresses the radial and ulnar arteries of the patient's hand to achieve a hemostatic effect. The cork column 41 has a uniform and moderate hardness to avoid the situation where a hard plastic compression object is compressed for a long time, causing blisters and bleeding in the hemostatic part. While compressing the radial or ulnar artery, it has little effect on the venous return of the hand, avoiding the situation of hand swelling; the anti-blocking venous return support column 5 is structurally shaped with the radial and ulnar artery compression column 4, and the anti-blocking venous return support column 5 is located beside the radial and ulnar artery compression column 4 to reduce the difficulty of venous return caused by bandaging.

[0025] In this embodiment, the surface of the first Velcro 2 on the same side as the outer gauze 11 is provided with a layer of hooked bristles, and the surface of the second Velcro 3 on the same side as the inner gauze 12 is provided with a side of fiber round hairs, the first Velcro 2 and the second Velcro 3 are adhered and connected, and the first Velcro 2 and the second Velcro 3 are adhered, and the adhesion position of the first Velcro 2 and the second Velcro 3 can be adjusted to adapt to patients' wrists of different thicknesses.

[0026] In this embodiment, an unconnected active cavity a and an active cavity b are formed between the outer gauze 11 and the inner gauze 12, the radial and ulnar artery compression column 4 is located inside the active cavity a, and the anti-blocking venous reflux support column 5 is located inside the active cavity b. The positions of the radial and ulnar artery compression column 4 and the anti-blocking venous reflux support column 5 can be adjusted to be in accurate positions. The surface of the outer gauze 11 is provided with an elliptical adjustment port 111 connected to the active cavity a and the active cavity b. The adjustment port 111 can be used to facilitate the adjustment of the positions of the radial and ulnar artery compression column 4 and the anti-blocking venous reflux support column 5.

[0027] In this embodiment, the diameter of the radial and ulnar artery compression column 4 is 25 mm, the diameter of the anti-blocking venous reflux support column 5 is 15 mm, the height of the radial and ulnar artery compression column 4 and the anti-blocking venous reflux support column 5 is the same, which is 35 mm. The radial and ulnar artery compression column 4 compresses the hemostasis position, and the anti-blocking venous reflux support column 5 is located beside the radial and ulnar artery compression column 4, which reduces the pressure on the vein at the compression point and avoids the occurrence of venous reflux difficulties.

[0028] In this embodiment, the length of the first Velcro 2 is 3 cm, and the length of the second Velcro 3 is 5 cm. The adhesion position of the first Velcro 2 and the second Velcro 3 can be adjusted to adapt to the wrists of patients with different thicknesses.

[0029] In this embodiment, the anti-loosening rubber ring 6 and the corresponding damping film 121 are opposite to each other, and the outer surface of the anti-loosening rubber ring 6 and the surface of the damping film 121 are provided with hemispherical rubber protrusions. The rubber protrusions on the anti-loosening rubber ring 6 and the corresponding damping film 121 are staggered, and the rubber protrusions increase the friction force. The anti-loosening rubber ring 6 and the damping film 121 provide friction resistance to prevent the ends of the radial and ulnar artery compression column 4 and the anti-blocking venous reflux support column 5 from being deflected and loosened.

[0030] The working principle and use process of this utility model:

[0031] The elastic bandage 1 is used to bandage the puncture site of the hand to stop bleeding, the first hook and loop fastener 2 is adhered to the second hook and loop fastener 3, and the adhesion position of the first hook and loop fastener 2 and the second hook and loop fastener 3 can be adjusted to adapt to the wrists of patients with different thicknesses;

[0032] The radial and ulnar artery compression column 4 compresses the puncture point to complete compression hemostasis and prevent the blocking of venous return. The support column 5 is located beside the radial and ulnar artery compression column 4 to reduce the pressure on the vein at the compression point and avoid the difficulty of venous return.

[0033] Through the adjustment port 111, the positions of the radial and ulnar artery compression column 4 and the anti-blocking venous return support column 5 can be conveniently adjusted;

[0034] The cork plug 41 of the radial and ulnar artery compression column 4 has a uniform and moderate hardness, which can prevent blisters and bleeding on the hemostatic part caused by long-term compression of a hard plastic compression object. It has little effect on the venous return of the hand while compressing the radial or ulnar artery, thus avoiding the swelling of the hand. The anti-blocking venous return support column 5 is also a gauze-covered cork structure, which is relatively soft and has a moderate hardness.

[0035] In summary: when the wrist is bandaged with pressure to stop bleeding, there is a design of soft compression on the puncture site. The radial and ulnar artery compression column 4 and the anti-blocking venous return support column 5 are made of gauze-covered corks. The corks are relatively soft and have moderate hardness, which can avoid blisters and bleeding in the hemostatic part caused by long-term compression, and also reduce the difficulty of venous return caused by the bandage.

[0036] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
