Description

一种药用覆膜合成聚异戊二烯垫片
技术领域
本发明涉及医药用品技术领域,具体为一种药用覆膜合成聚异戊二烯垫片。
背景技术
传统的药用输液组合盖由外盖+异戊二烯垫片+内盖,因内盖由PP材料制成,导致了实际使用时穿刺较困难,穿刺落屑较大,给输液造成一定的困难和影响。
为解决这些问题,我们在输液组合盖的开发设计中已实现取消内盖,使胶垫产品直接与药液接触,因此需要在现有药用组合盖的生产技术和工艺技术方面进行改进和创新。
发明内容
本发明的目的在于提供一种药用覆膜合成聚异戊二烯垫片,其采用全新的配方设计,克服了传统异戊垫片配方的与膜材料粘合性差的缺点,垫片直接与药液接触,从而省去了组合盖的内盖部分,减小了穿刺过程中的阻力,降低了穿刺落屑的产生,更便于医院使用。
本发明解决技术问题采用如下技术方案:
提供一种药用覆膜合成聚异戊二烯垫片,其特征在于:其配方按质量份为:聚异戊二烯橡胶:100,高岭土:15-20,白炭黑:5-10, 氧化锌:5,炭黑:0.3 ,钛白粉:4,硫化剂:1.2。
作为优选实例,所述的覆膜材料厚度为2mil的ETFE膜。
一种药用覆膜合成聚异戊二烯垫片,其特征在于其生产工艺流程如下:
(1)配料:按配方进行各种材料的配制,放在指定的料洞内;
(2)炼胶:按配方将各种材料混炼均匀;
(3)预成型:根据要求将胶料制成便于硫化规定尺寸重量的胶片;
(4)一次硫化:在平板硫化机上放入配方胶料和膜材料形成胶塞药物接触部分,硫化温度为200℃;
(5)一次除边:将药物接触部分冲切成一次硫化胶塞;
(6)二次硫化:将一次硫化胶塞放入平板硫化模具,加入二次硫化胶片,形成二次硫化产品,硫化温度为250℃;
(7)二次除边:冲切成成品;
(8)清洗:采用自动清洗清洗胶垫;
本发明与现有的技术相比,其有益效果为:其采用全新的配方设计,克服了传统异戊垫片配方的与膜材料粘合性差的缺点,完成后的胶垫产品直接与药液接触,从而省去了组合盖的内盖部分,经各种试验验证,完全能够满足直接接触输液药品的相关要求,特有的结构设计,在使用过程中减小了穿刺过程中的阻力,降低了穿刺落屑的产生,更便于医院使用。
