Description

喷雾型润滑防锈剂及其制备方法
技术领域
本发明涉及一种喷雾型润滑防锈剂及其制备方法,属于医疗器械用助剂技术领域。
背景技术
随着医疗技术的不断发展,人工关节置换、器官移植以及瓣膜置换术等高新技术发展迅速,贵重复杂精密器械的广泛应用,对手术器械的清洗、消毒、润滑、保养以及包装灭菌等提出的要求更高,外科手术器械种类繁多,价格贵重,形状不一,要做好保养,延长器械使用寿命,上油显得尤为关键。润滑防锈剂的工作原理是在医疗器械表面形成一层可被灭菌因子穿透的保护膜,有效防止空气中的氧气与不锈钢器械接触,从而达到防止器械轴节僵硬、生锈。目前应用普及的方法为机器上油,但存在以下方面的不足:
一方面,机器上油相对来说方法简单,可操作性强,但是机器用的润滑防锈剂稀释比例较高,导致部分器械的关节、轴节等部位出现不灵活,此时这些器械需要进行再次补充润滑。按照相关规定,这些器械需要重新通过传递窗进入去污区进行润滑、干燥。这种情况会降低整包器械的处理速度,降低消毒供应中心的工作效率,从而导致医院的运营成本增加。
另一方面,机器上油的局限性较大,遇到下列情况仍需人工上油。例如,不能水洗的贵重复杂精密手术器械的各关节、轴节等部位。传统的擦拭上油法极易使器械关节、轴节等部位粘上纤维丝屑,造成污染。另外,擦拭上油无法擦拭到不能完全打开的部分及轴关节的缝隙处,从而导致这些部位的轴关节不灵活,大大提高了器械的生锈率,缩短了器械的使用寿命。
基于以上情况,研发一种用于外科器械的具有良好干燥效果及良好稳定性的喷雾型润滑防锈剂具有很大市场前景。
发明内容
本发明的目的是提供一种喷雾型润滑防锈剂,其原材料环保易得,干燥速度快、润滑效果好、水溶性好且能被灭菌因子完全穿透;本发明同时提供了简单易行的制备方法。

Figure BDA0001175811530000022
优选的,基础油为医用矿物油。
优选的,乳化剂体系为失水山梨醇脂肪酸酯、聚氧乙烯失水山梨醇脂肪酸酯或油酸三乙醇胺中的一种或多种。
优选的,助乳化剂为碳链为C12-C18的脂肪醇、碳链为C12-C18的脂肪酸、十二烷基硫酸钠、十二烷基苯磺酸钠、十二烷基聚氧乙烯醚磺基琥珀酸单酯二钠盐中的一种或多种。

优选的,推进剂为液化石油气、丙烷、正丁烷、异丁烷、二甲醚、二氯二氟甲烷、三氯一氟甲烷、二氯四氟乙烷或四氟乙烷中的一种或多种。
所述的喷雾型润滑防锈剂的制备方法,将所述的基础油、乳化剂、助乳化剂和溶剂混合,加入到带有喷雾阀的罐中,并通过喷雾阀在0.4-0.6MPa压力下向罐中加入推进剂,制得所述的喷雾型润滑防锈剂。
所述的喷雾型润滑防锈剂的自干燥时间小于60s。
具体实验方法如下:将不锈钢钢片放入电子天平上(电子天平测量精度为0.001g),然后将所述的喷雾型润滑防锈剂(约1.0g)均匀喷洒在钢片上,并开始计时直至电子天平示数不再发生变化,所用时间即为自干燥时间。
相对现有技术配方,本发明配方的优势在于以基础油、乳化剂、助乳化剂以及溶剂为母液,并通过喷雾阀在一定压力下向罐中加入推进剂,制得喷雾型润滑防锈剂。在推进剂作用下,液体喷洒到器械表面后,配方中的溶剂可以快速挥发,然后将具有润滑成分的基础油留在器械表面。

(2)所述的喷雾型润滑防锈剂,操作简单,可直接喷洒在器械上,无需干燥设备,干燥效果好。
(3)所述的喷雾型润滑防锈剂,用于医疗器械的常规手工润滑保养特别是管腔器械及精密复杂手术器械的润滑保养,具有良好的润滑效果。
(4)所述的喷雾型润滑防锈剂,有效延长器械的使用寿命,降低医院的成本。
(5)本发明同时提供了简单易行的喷雾型润滑防锈剂的制备方法。
