preparation example Construction

[0074] In the method for preparing an artificial blood vessel provided in this example, polyvinyl alcohol, dimethyl sulfoxide, and water are mixed according to a preset ratio to obtain a mixed solution, the mixed solution is heated to obtain a casting solution, and the casting solution is cast into the artificial blood vessel. in the mold model. After cooling and demolding, the artificial blood vessels obtained are highly similar to real blood vessels in terms of toughness, permeability, biocompatibility and elasticity. The artificial blood vessel can be applied to the fields of medical disease research, disease treatment and medical auxiliary teaching. As an alternative basis for individualized blood vessels in clinical vascular surgery, the artificial blood vessels can improve the reliability of medical research, treatment and teaching.

Abstract

The embodiment of the invention provides a method for preparing an artificial blood vessel and the artificial blood vessel. The method includes the following steps that an artificial blood vessel mould is prepared based on a three-dimensional digital model of a blood vessel; polyvinyl alcohol, dimethyl sulfoxide and water are mixed according to a preset proportion to obtain mixed liquor; the mixed liquor is heated to obtain casting liquor; the casting liquor is cast into the artificial blood vessel mould; the casting liquor is cooled, the artificial blood vessel mould is removed, and the artificial blood vessel is obtained. According to the technical scheme, the artificial blood vessel with high consistency with a true blood vessel can be obtained.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a method for preparing an artificial blood vessel and the artificial blood vessel. Background technique [0002] With the development of modern medicine, various biomedical models can be established to conduct research on diseases or assist in teaching. For example, human acupuncture models, diagnostic skills models, pregnancy and infant skills models, etc. The above models are mainly used for teaching assistance, and there is no high requirement for the simulation of the models. For disease research, biomedical models need to be similar in structure to real organisms to help improve the accuracy of research results. For example, artificial blood vessels are required in the study of many diseases. The consistency of artificial blood vessels used in research with human blood vessel structures is a key factor in determining the reliability of research results. [0003] I...
