Silicified latex balloon as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of medical instrument preparation, and discloses a silicified latex balloon and a preparation method thereof. The preparation method comprises the following steps that (1) soaking a balloon mold in a mixed coagulator; (2) dipping the balloon mold into pre-vulcanized latex; (3) soaking the balloon mold in a coagulator solution to obtain a formed balloonlatex film; (4) soaking the balloon latex film in water, taking the film out and drying the balloon latex film; and (5) demolding the dried balloon latex film, dipping the latex balloon in an organicsilicon emulsion, taking out the latex balloon, and curing at 100-130 DEG C to obtain the silicified latex balloon. Compared with the prior art, the silicified latex balloon provides a larger ballooncapacity choice, the good tensile strength of latex endows the catheter balloon with the filling amount of enough capacity, the maximum filling amount of the latex balloon reaches 200 ml, and the problem that compression hemostasis is conducted through a balloon is well solved.

Description

technical field [0001] The invention relates to the technical field of medical device preparation, in particular to a siliconized latex balloon and a preparation method and application thereof. Background technique [0002] In the prior art, the balloon material of the silicone urinary catheter is also made of silicone material. Due to the poor elasticity of silicone, the maximum balloon capacity can only be filled with 30-50 ml, and the balloon is easy to burst due to excessive pressure , For some operations that need to fully inflate the balloon to a large size for compression and hemostasis, because the balloon is likely to be inflated to a small size and lack sufficient compression force, the amount of bleeding will be increased or the flushing time during the operation will be prolonged. [0003] In addition, the molecules of the silicone balloon material are relatively loose, and the silicone catheter needs to be supplemented with sterile water or normal saline every 2...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the balloon material of the silicone urinary catheter is also made of silicone material. Due to the poor elasticity of silicone, the maximum balloon capacity can only be filled with 30-50 ml, and the balloon is easy to burst due to excessive pressure , for some operations that need to fully inflate the balloon to a large size for compression and hemostasis, because the balloon filling is likely to be small and lack sufficient compression force, which will increase the amount of bleeding or prolong the flushing time during the operation

[0003] In addition, the molecules of the silicone balloon material are relatively loose, and the silicone catheter needs to be supplemented with sterile water or normal saline every 2-3 days during the indwelling process, which brings inconvenience to patients who need to indwell the catheter for a long time , a burden on medical staff

[0004] At present, domestic enterprises or scientific research institutes have not effectively solved this problem, and a few manufacturers in developed countries in Europe and the United States have developed high-strain, high-elastic silicone balloon materials, but the technology is strictly confidential, and the raw materials are never sold to the outside world.
