Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the sizing sleeve used in the production of medical catheters more clear, the present invention will be further described in detail below in conjunction with specific drawings and specific embodiments.

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] Different from ordinary PVC pipes, medical catheters are in contact with human tissues, blood, body fluids, etc., and some are even permanently implanted in the body. Therefore, medical catheters must have excellent bioreplaceability, biocompatibility and blood compatibility. It requires a smooth surface, non-toxic, odorless, and disinfection-resistant. In addition, medical catheters are required to have certain physical and mechanical properties such as tensile strength and elasticity. Therefore, in order to better adapt to...

Abstract

The invention provides a fixed-diameter sleeve for producing a medical catheter. The fixed-diameter sleeve comprises a fixing disc, a cover plate, a front end shaping column, a front end shaping through hole, a front end air groove and a rear end shaping column, wherein a fixing disc through hole is formed in the center of the fixing disc, the cover plate is fixed to the fixing disc, an installing cavity is formed between the cover plate and the fixing disc, the front end shaping column is arranged in the installing cavity and fixed to the fixing disc and the cover plate, the front end shaping through hole is formed in the center of the front end shaping column, the front end air groove is formed in the side wall of the front end shaping through hole, the rear end shaping column and the cover plate are fixed to two sides of the fixing disc respectively, a rear end shaping through hole is formed in the center of the rear end shaping column, a rear end air groove is formed in the side wall of the rear end shaping through hole, and the fixing disc through hole, the front end shaping through hole and the rear end shaping through hole are arranged coaxially. The outer wall of the medical catheter obtained by using the fixed-diameter sleeve for producing the medical catheter is high in smoothness and good in shaping effect, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of production, in particular to a sizing sleeve for the production of medical catheters. Background technique [0002] With the development of catheter diagnosis and treatment technology, the clinical application of medical catheters is developing day by day, and the demand is increasing. With the development of society and economy, the level of medical care is constantly improving, and clinical requirements for medical catheters are constantly being raised, so this requires continuous innovation of medical catheters to meet clinical needs. [0003] Medical catheters have the characteristics of small size, complex shape, high geometric precision requirements, high hygienic indicators, and high biochemical stability. Therefore, the production of precision medical catheters is very difficult, and conventional processing equipment and processes cannot meet its production requirements. At present, a large part of precis...
