Description

一种检验科用抑菌注射器针头及其表面处理方法
技术领域
本发明属于医疗器械制造领域，涉及了一种检验科用抑菌注射器针头及其表面处理方法。
背景技术
无菌注射器针头是用于将液体注入到皮下或从中抽取液体，单次无菌注射器针头使用方便，但对于体弱婴幼儿及老人，当需连续多次注射时，会由于多次扎针引起巨大疼痛，甚至会由于多次扎针导致皮下组织受损严重，引起感染。因此，对于多次连续注射时，往往避免单次无菌注射针，采用可连续多次注射使用的一次性注射针，从而避免由于多次扎针引起的组织损伤及严重的疼痛。但多次注射使用的注射针由于与皮肤组织接触时间较长，必须具备良好的生物相容性和抗菌性。
中国专利“申请号：201220718079.8”报道了一种一次性使用无菌溶液注射器，通过设置防护罩，减少针头细菌感染，但不能再使用过程中提高其抗菌性。中国专利“申请号：201910373641.4”报道了一种用于连续多次定量注射的一次性注射器，通过设置定位装置，提高定位精度，实现连续、多次、定量注射。中国专利“申请号201711295934.2”报道了一种医用设备专用表面疏水抗菌涂层及其制备工艺，通过等离子喷涂技术将疏水抗菌涂层喷到医用设备表面，实现抑菌、疏水、耐磨、耐腐和除味的作用。
发明内容

技术方案：为实现上述目的，本发明通过以下方案实施。
一种检验科用抑菌注射器针头，基体为不锈钢，所述注射器针头基体表面沉积Ta@DLC+ZnBAgN交替分布的纳米叠层涂层。该叠层涂层至少含有1层Ta@DLC层和1层ZnBAgN层，且Ta@DLC和ZnBAgN单个层的厚度小于等于50nm。
上述一种检验科用抑菌注射器针头基体表面沉积的Ta@DLC+ZnBAgN涂层采用多弧离子镀+中频磁控溅射共沉积的方法制备。
上述一种检验科用抑菌注射器针头表面涂层沉积处理方法具体步骤如下：
(1)将注射器针头放在酒精溶液中超声清洗20-30min，干燥后进行表面涂层处理；
(2)将干燥后的注射器针头放入镀膜机真空室，真空室本底真空为8.0×10-3-10.0×10-3Pa，加热至150-220℃，保温时间20-30min；
(3)通入Ar气，其压力为0.5-0.8Pa，开启偏压电源，电压600-800V，占空比0.2-0.3，辉光放电清洗20-30min；偏压降低至100-120V，开启离子源离子清洗20-30min，开启石墨阴极电弧电源，偏压150-250V，靶电流20-35A，离子轰击石墨靶1.0-1.5min；
(4)调整工作气压为0.4-0.5Pa，偏压80-100V，开启中频Ta靶，调整电流10-15A，电弧镀Ta掺杂DLC涂层0.5-5.0min，完成Ta@DLC涂层制备，关闭石墨靶和Ta靶；
(5)调整工作气压至0.6-1.0Pa，偏压至120-150V，开启ZnBAgN复合靶材，调整电流25-30A，中频磁控溅射沉积ZnBAgN涂层0.5-5.0min，关闭ZnBAgN复合靶；
(6)重复步骤(4)和(5)，交替沉积Ta@DLC+ZnBAgN纳米叠层涂层，使涂层总厚度为50-300nm；
(7)关闭所有靶材、偏压电源、离子源及气体源，保温20-30min，涂层结束。
有益效果：与现有技术相比，本发明的注射器针头表面Ta@DLC涂层具有良好的生物相容性，ZnBAgN涂层具有良好的抑菌性，两者结合制备出的Ta@DLC+ZnBAgN纳米叠层涂层能够同时增强生物相容性和抑菌性，提高针头使用寿命。另一方面，本发明制备方法可操作性强，涂层与基体结合强度高，涂层内应力小。
