[종래기술][Private Technology]

일반적인 주사기용 흡자는 대부분 염화 비닐 합성수지(polyvinylchlorideresin)를 사용하고 있으며, 그 제조 방법에 있어서는 주사기용 밀대를 제조하고 염화 비닐 합성수지를 이용한 흡자를 사출·성형하여 제조한 후 상기의 밀대와 결합하여 완성한다. 하지만 이와 같이 흡자의 성분으로서 염화 비닐 합성수지를 사용하면 천연고무에 비하여 가소제, 촉매 등의 사용으로 인한 환경오염을 유발할 수 있으며, 주사기용 흡자를 별도의 사출·성형 공정으로 제작하여 밀대와 결합하는 복잡한 제조 공정으로 인하여 원가 상승요인을 유발하는 문제가 있다.In general, the inhaler for syringes is made of polyvinylchlorideresin, and in the manufacturing method thereof, a syringe rod is prepared, and an intake molded using vinyl chloride synthetic resin is injected and molded, and then combined with the rod. . However, the use of vinyl chloride synthetic resin as the component of the intake can cause environmental pollution due to the use of plasticizers, catalysts, etc., compared with natural rubber. There is a problem that causes a cost increase factor due to the manufacturing process.
