AI Technical Summary
Existing hemostatic devices cannot control the tightening degree of the two pressurized blood cloths separately, which can easily cause damage to the limbs or poor bleeding when the pressurized blood cloth is too tight or loose.
A hemostatic device is designed. By setting up an elastic baffle, an inner cylinder and a double-sloped groove, the prism rotation is driven by a double-headed motor. The inner cylinder pushes the elastic baffle through the double-sloped groove to control the tension of the winding wheel on the blood pressure cloth, thereby achieving independent control of the tightening degree of the blood pressure cloth.
It is achieved that the final tightness of the compressed blood cloth can be controlled separately when tightening the compressed blood cloth at the same time, avoiding damage to the limbs, and improving the effect of hemostasis.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hemostasis, in particular to a hemostasis device. Background Art
[0002] In medical care, nursing staff often need to perform long-term compression hemostasis care on the patient's artery. When bleeding occurs in the human limbs, pressure is generally applied to both sides of the bleeding site to reduce the blood flow to the bleeding site, thereby achieving the effect of hemostasis. However, the effect of manual compression hemostasis is very poor. Therefore, compression hemostasis devices are often used for hemostasis.
[0003] The hemostatic device in the prior art stops bleeding by tightening the hemostatic cloths on both sides of the bleeding area. The tightened hemostatic cloths on both sides apply a large force on both sides of the bleeding area to stop bleeding. However, different parts of human limbs have different thicknesses. When tightening two hemostatic cloths at the same time, the tightening degree of the two hemostatic cloths cannot be controlled separately. When the hemostatic cloths are too tight, it is easy to cause damage to the limbs. When the hemostatic cloths are too loose, it is easy to cause poor hemostasis. Therefore, a hemostatic device is proposed. Utility Model Content

[0030] The hemostatic cloth is tightened on both sides of the bleeding area and the hemostatic cloth is passed through both sides of the bleeding area to apply a strong force to stop the bleeding.
[0031] In the related art, different parts of the limbs have different thicknesses. When two blood-compressing cloths are tightened at the same time, the tightening degree of the two blood-compressing cloths cannot be controlled separately. When the blood-compressing cloths are too tight, it is easy to cause damage to the limbs, and when the blood-compressing cloths are too loose, it is easy to cause poor hemostasis.
[0032] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a hemostatic device. When it is needed, it is only necessary to start the double-headed motor 3 to drive the two prism shafts 5 to rotate synchronously, and the inner cylinder 4 rotates synchronously with the prism shaft 5. The inner cylinder 4 drives the winding wheel 6 to wind the blood-pressing cloth 8 through the elastic baffle 12 located inside the double-bevel groove 11. After the winding wheel 6 drives the blood-pressing cloth 8 to tighten and fit with the limbs, when the inner cylinder 4 continues to rotate, the double-bevel groove 11 pushes the elastic baffle 12 to gradually bend and displace with the inner cylinder 4, so that the winding wheel 6 It can rotate in a dislocated manner with the inner cylinder 4, and the edge rod 9 is pulled to change the position of the slider 10 and the elastic baffle 12 relative to the inner cylinder 4, so that the two elastic baffles 12 are respectively located at different depths of the two inner cylinder double-bevel grooves 11. The depths of the double-bevel grooves 11 at different positions make the elastic baffle 12 bend to different degrees and be dislocated with the inner cylinder 4, so that the winding wheel 6 exerts different degrees of pulling force on the taut blood-squeezing cloth, and controls the tightening degree of the blood-squeezing cloth 8. At the same time, after one blood-squeezing cloth 8 is tightened, the other winding wheel 6 can continue to tighten the other blood-squeezing cloth 8.
