Embodiment 1

[0017] An aortic perfusion tube with an elastic hemostatic ring, the aortic perfusion tube with an elastic hemostatic ring includes an aortic perfusion tube body 1, a fixing ring 2, an elastic body 3, a soft compression tube made of polyvinyl chloride Ring 4;

[0018] The elastic body 3 is four sheet elastic bodies made of nylon;

[0019] The fixing ring 2 is set on the main body 1 of the aortic perfusion tube and fixed with the main body 1 of the aortic perfusion tube. The soft pressure ring 4 is set on the main body 1 of the aortic perfusion tube. Distributed on the main body 1 of the aortic perfusion tube, and one end of the sheet-shaped elastic body is connected to the fixed ring 2, and the other end is connected to the soft pressure ring 4;

[0020] When the four sheet-shaped elastic bodies are deformed, the soft pressure ring 4 can move on the main body 1 of the aortic perfusion tube.

Embodiment 2

[0024] An aortic perfusion tube with an elastic hemostatic ring, the aortic perfusion tube with an elastic hemostatic ring includes an aortic perfusion tube body 1, a fixing ring 2, an elastic body 3, and a soft plastic made of low-density polyethylene. Pressure ring 4;

[0025] The elastic body 3 is a stainless steel spring;

[0026] The fixing ring 2 is set on the main body 1 of the aortic perfusion tube and fixed with the main body 1 of the aortic perfusion tube, the stainless steel spring is set on the main body 1 of the aortic perfusion tube, and the soft pressure ring 4 is set on the main body of the aortic perfusion tube On the body 1, one end of the stainless steel spring is connected to the fixed ring 2, and the other end is connected to the soft pressure ring 4;

[0027] When the stainless steel spring is compressed, the soft pressure ring 4 can move on the main body 1 of the aortic perfusion tube.

Abstract

The invention relates to an aortic perfusion tube with an elastic hemostatic ring, belonging to the technical field of medical instruments. The aortic perfusion tube with an elastic hemostatic ring comprises an aortic perfusion tube body, a fixing ring, an elastomer and a flexible compression ring. The fixing ring is sleeved on the aortic perfusion tube body and fixed with the aortic perfusion tube body. The flexible pressing ring is sleeved on the aortic perfusion tube body and connected with the fixing ring through an elastomer. When the elastomer is deformed, the flexible pressing ring is movable on the aortic perfusion tube body. As the flexible pressure re has elasticity, the aortic perfusion tube with the elastic hemostatic ring of the invention can be naturally adhere to and pressedon the arterial wall without adjusting the position, and the arterial wall is compressed to prevent blood leakage around the intubation when the aortic perfusion tube is used.

Description

technical field [0001] The invention relates to an aortic perfusion tube with an elastic hemostatic ring, which belongs to the technical field of medical instruments. Background technique [0002] Aortic perfusion tube is one of the routinely used consumables in cardiopulmonary bypass surgery. The positioning ring of the existing aortic perfusion tube needs to be temporarily installed before use, or the position needs to be adjusted according to the diameter of the aorta, which is extremely inconvenient to use and has no hemostatic function. Contents of the invention [0003] The present invention solves the above problems by improving the structure of the existing aortic perfusion tube. [0004] The invention provides an aortic perfusion tube with an elastic hemostatic ring. The aortic perfusion tube with an elastic hemostatic ring includes an aortic perfusion tube body, a fixing ring, an elastic body, and a soft pressure ring; the fixing ring Covered on the main body o...
