Semi-coated pressing hemostasis device

Abstract

The invention discloses a semi-coating type pressing hemostasis device that comprises a first clamping piece, a second clamping piece and a pressing piece, wherein a pressing piece is arranged at thecorresponding position of the inner side arc surface of each of the first clamping piece and the second clamping piece; one ends of the first clamping piece and the second clamping piece are hinged, the other ends of the first clamping piece and the second clamping piece are closed and fixed through a torsion clamp structure, each pressing piece comprises an arc-shaped pressing plate and a spring,and each arc-shaped pressing plate is connected with the clamping piece on the corresponding side. The hemostatic device is simple in structure, more convenient to operate by opening and closing thetorsion clamp structure, and suitable for being used under the working condition of a single person; the artery hemostasis process is achieved through a semi-coated type pressing structure, bad consequences such as limb necrosis caused by long-time complete disconnection of blood supply and venous return of the far end of the limb can be avoided, and the health of a wounded person is guaranteed.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a semi-covered pressing hemostasis device which can avoid completely blocking the blood supply of distal limbs. Background technique [0002] When encountering various accidental injuries, if the arterial rupture and bleeding occur in the limbs of the human body, due to the high arterial pressure and the fast bleeding speed, if the hemostatic process is not timely and effective, it will soon be life-threatening. It is a simple and effective method of hemostasis in first aid. It achieves the purpose of hemostasis by blocking blood flow by compressing blood vessels. However, the existing arterial tourniquet needs to be continuously and seamlessly strongly pressed around the limb during use to form the effect of completely disconnecting the blood supply and venous return at the distal end of the limb. Therefore, the use time of the tourniquet is limited. Once the continuous time is ...

Problems solved by technology

However, the existing arterial tourniquet needs continuous and seamless strong pressure around the limb to form the effect of completely disconnecting the blood supply and venous return at the distal end of the limb.

Therefore, the use time of the tourniquet is limited. Once the continuous time is too long (the Chinese academic circle limits 45 minutes, and the US law limits 2 hours), it will bring the risk of distal limb necrosis, and severe cases may even require amputation

[0003] For this reason, when manpower conditions are available, the indirect pressing method is often used to stop bleeding. However, when manpower conditions are not available, such as when only the wounded are on the scene, or when others cannot provide help in time and foreign aid takes a long time, there is a machine that can A hemostatic device that simulates indirect pressure hemostasis is very necessary
