Manufacturing method for fixed-height notch protection expander

Abstract

The invention discloses a manufacturing method for a fixed-height notch protection expander. An inner clamp ring and an outer clamp ring are manufactured; then, the outer clamp ring is arranged over the inner clamp ring; and silica gel materials are shot into a glue inlet in the outer clamp ring, after shooting is finished, vulcanization is conducted, a tubular protection film is formed to connectthe inner clamp ring with the outer clamp ring together, and the fixed-height notch protection expander is formed. Silica gel layering vulcanization is adopted, and usage of an existing manufacturingmethod is avoided. The fixed-height notch protection expander is smooth and free of groove forming, and blood, waste liquid and the like of patients cannot be reserved in any place. Meanwhile, the fixed-height notch protection expander is free of burrs and corners so that the human body cannot get hurt. The positions between the clamp rings and the tubular protection film cannot slide, and doctoroperation becomes more convenient and simple. Adding of a bonding agent and other chemical reagents is avoided, no harm is caused to the human body, and environment friendliness is achieved. The manufacturing technology is rapid, simple, safe and effective.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for manufacturing a height-fixed incision protection dilator. Background technique [0002] Silicone is the main material for the height-fixed incision protection dilator. Currently, there are two models of this incision protection dilator on the market, namely 100 / 50 and 150 / 70. The production of this kind of incision protection dilator is firstly extruded from polyethylene material, after the extruded tubes are butt-jointed, the hot-melt spillage produced by welding is removed, and then the tubular protective film is vulcanized by silica gel, and the tubular protective film is placed on the The polyethylene ring is wrapped around the polyethylene ring and finally glued with an adhesive. [0003] The defective that above-mentioned production method exists is as follows: [0004] 1. The use of adhesives for bonding will produce some grooves. During use, blood and wast...

AI Technical Summary

Problems solved by technology

[0004] 1. The use of adhesives for bonding will produce some grooves. During use, blood and waste liquid will remain in the grooves, which will be harmful to the health of patients, and the residual blood is not conducive to garbage disposal and environmental protection. There is biological contamination;

[0005] 2. The tubular protective film will produce a small amount of edges and corners after bonding, which may scratch human tissues during use, thereby causing harm to the human body;

[0006] 3. A tubular protective film made of silicone material is used to wrap the inner and outer snap rings of polyethylene material, and there will be a certain amount of sliding between the snap ring and the tubular protective film, which will cause inconvenience to the doctor's operation;

[0007] 4. The use of adhesives for suturing is harmful to the human body and is not conducive to the health of patients, and the adhesives are more harmful to the environment

[0008] 5. There are many processes
