Embodiment Construction

[0016] The present invention will be further described below:

[0017] The present invention comprises the following steps:

[0018] S1: Prepare natural rubber, vinyl resin, polyamic acid resin, oleic acid, polyvinyl alcohol, polyurethane, highly active polymer polyol, ethylene glycol, silicon carbide grains, diphenylmethane diisocyanate and zirconia for use ;

[0019] S2: Add natural rubber into the container for heating and melting, then add vinyl resin and polyamic acid resin in the heat preservation state to stir until the mixture is uniform;

[0020] S3: After stirring evenly, let it stand for 10 minutes in a heat preservation state; continue to add oleic acid, polyvinyl alcohol, polyurethane, highly active polymer polyol, and ethylene glycol for high-speed stirring, and the stirring time is 30 minutes;

[0021] S4: Continue to add silicon carbide grains, diphenylmethane diisocyanate and zirconia and continue to stir, stir and mix evenly and keep warm for later use;

Abstract

The invention discloses a thrombus cleaning pipe manufacturing process. The thrombus cleaning pipe is prepared from natural rubber, vinyl resin, polyamide acid resin, oleic acid, polyvinyl alcohol, polyurethane, high-activity polymer polyol, ethylene glycol, silicon carbide crystal grains, diphenylmethane diisocyanate and zirconium oxide. Compared with the prior art, the surface lubricity of the natural rubber medical pipe is improved, friction damage to blood vessels in the process that the medical pipe is guided into a human body can be reduced, friction resistance is reduced, operation of medical staff is facilitated, the interventional therapy efficiency is improved, and the process has value for popularization and application.

Description

technical field [0001] The invention relates to a medical device, in particular to a manufacturing process of a thrombus clearing tube. Background technique [0002] In the prior art, there are methods of drug therapy and surgical treatment for cleaning thrombus. For the thrombus cleaning pipeline for surgical treatment, the existing pipeline has a large friction force, which makes the pipeline pass through the blood vessel not smooth enough, making it inconvenient for medical staff to operate. This results in suboptimal treatment outcomes, and therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a thrombus clearing tube material manufacturing process in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The present invention comprises the following steps: [0006] S1: Prepare natural rubber, vinyl resin, ...
