Title:
ARTIFICIAL BLOOD VESSEL
Document Type and Number:
WIPO Patent Application WO/2020/181430
Kind Code:
A1
Abstract:
Provided is an artificial blood vessel. The artificial blood vessel comprises an outer-layer blood vessel (1), wherein an inner-layer blood vessel (2) is nested in the outer-layer blood vessel (1), and a joint (3) connected to the inner-layer blood vessel (2) is provided on an inner wall of the outer-layer blood vessel (1), and the joint (3) is connected to one end or the middle of the inner-layer blood vessel (2). By nesting the inner-layer blood vessel (2), connected to the inner wall of the outer-layer blood vessel, in the outer-layer blood vessel (1), the outer-layer blood vessel (1) is connected when the artificial blood vessel is connected, and the length of the inner-layer blood vessel (2) is greater than that of the outer-layer blood vessel (1) for anastomosis, that is, the length of the inner-layer blood vessel (2) exceeds that of an anastomotic stoma. When blood flows through the inner-layer blood vessel (2), the blood flow pressure enables the inner-layer blood vessel (2) to be attached to the anastomotic stoma, so that the anastomotic stoma and suture stitches can be closed, isolated and pressed, thereby achieving the effect of preventing the anastomotic stoma and the suture stitches from bleeding, and making the artificial blood vessel safer and more convenient to use.
