Balloon catheter manufacturing method and device using thermosetting resin

Abstract

The present invention relates to a method for manufacturing a balloon catheter using a thermosetting resin, and its object is to provide a method that utilizes the curing characteristics of the thermosetting resin to combine the drying process after applying the release agent and the curing process, so as to rapidly manufacture a Cost-effective method of manufacturing balloon catheters using thermosetting resins.

Description

technical field [0001] The present invention relates to a method for manufacturing a balloon catheter using a thermosetting resin and a device thereof. Specifically, by utilizing the curing properties of the thermosetting resin, after the release agent is applied, the drying process and the curing process are combined, so that a continuous process can be used to rapidly manufacture a balloon catheter. A cost-effective method of manufacturing a balloon catheter using a thermosetting resin. Background technique [0002] As we all know, the so-called thermosetting resin is a low-molecular-weight resin that generates a three-dimensional network structure polymer through a cross-linking reaction through heat, catalysis, ultraviolet light, etc., and a typical one is silicone rubber. [0003] Due to the characteristics of this thermosetting resin, in the low-molecular resin state before curing, as an amorphous substance, it can be deformed under the action of external force, but af...

Problems solved by technology

This method removes the complicated process related to the balloon, and is simpler than the existing method, but it needs the air lumen perforation, coating of release agent and drying process. It is inevitable to cut and process the extruded tube once, so the working process is interrupted. , unable to produce continuously, resulting in high manufacturing cost

[0009] The patent registration number 10-0689238 is to make up for the defects of the above-mentioned 10-043720, and proposes a continuous production method, but the problem in this patent is that when the air lumen is perforated with a laser, soot is left at the perforated part, and the tube in the manufacturing process There is a danger of fire, and the drying process after coating the release agent has not been specified

However, when forming a balloon using a variable die, if the extruder die end portion cannot be directly solidified, the primary extruded material and the secondary extruded material contact each other to form a balloon, so the extruded material cannot be solidified immediately after extruding. speed up to a certain extent

It is directly related to production speed, resulting in increased unit cost

[0016] The prior art is, as mentioned above, complex manufacturing process, high manufacturing cost, or due to various restrictions, its applicability will be limited, so it is particularly necessary to improve
