Abstract

The patent of the present invention relates to a device for casting blood vessels, which solves the problems of slow printing and easy collapse of biological materials in the existing bioprinting technology. The blood vessel casting and forming device comprises a base, a central shaft, an inner hole support, a middle hole support, an outer hole support, a liquid inlet, a liquid outlet, an inner cavity, a middle cavity, an outer cavity, and an end cover. The characteristics of the present invention are: through the distribution of the porous scaffold, the cells are distributed according to a certain size and the porous scaffold material can be a degradable material; the liquid inlet and the liquid outlet can continuously supply the nutrient solution to the cells; after pouring, The cells of different layers are cultured through the nutrient solution to achieve cell growth, thereby obtaining artificial blood vessels. The invention has the advantages of simple and convenient operation, and can rapidly produce blood vessels in large quantities.

Description

technical field [0001] The invention relates to blood vessel manufacturing technology in the field of tissue engineering, and relates to a blood vessel pouring forming device and method. Background technique [0002] With the improvement of people's living standards and the aggravation of social aging, the incidence of cardiovascular and cerebrovascular diseases is increasing year by year and becoming younger. Cardiovascular disease is a disease with a high mortality rate in today's society. According to data surveys, cardiovascular disease ranks first among the overall status indicators of the Chinese population. The treatment of some cardiovascular diseases (such as aneurysm, arterial thrombosis, cardiac artery bypass, traumatic vascular injury, etc.) needs to be carried out through artificial blood vessel transplantation, and the manufacture of artificial blood vessels with human applicability is the key to this kind of vascular diseases. [0003] With the development of...
