Abstract

本发明提供一种隐藏缠绕毁型式一次性安全采血针,其结构是由前针柄、后针柄和针体组成,针体通过注塑工艺设置在前针柄和后针柄之中,针体的左端加工有针尖,针尖位于前针柄之中,前针柄与后针柄之间通过针体和连杆连接,前针柄和后针柄上分别设置有凹槽,凹槽的端部分别于连杆的端部连接,本发明的有益效果:1)结构简单,易于加工、节省原料和使用方便;2)采用推出的方式将针尖推出前针柄,使用完后再通过折弯的方式让伸出前针柄外的针尖缩回到前针柄之中进行隔离隐藏,再通过将针体缠绕在连杆上方式进行毁型,防止针尖对环境的二次污染和人体的意外伤怀,具有很好的安全防污染效果。

Description

一种隐藏缠绕毁型式一次性安全采血针
技术领域
本发明涉及医疗器械技术领域,具体地说是一种隐藏缠绕毁型式一次性安全采血针。
背景技术
现有技术的采血针在使用过程中存在的最大不足是安全性差,使用完的采血针针尖完全暴露在外,不仅造成二次环境污染,也存在对他人意外伤害和感染的潜在危险,目前没有好的办法解决。
发明内容
本发明的技术任务是解决现有技术的不足,提供一种隐藏缠绕毁型式一次性安全采血针。
本发明的技术方案是按以下方式实现的,其结构是由前针柄、后针柄和针体组成,针体通过注塑工艺设置在前针柄和后针柄之中,针体的左端加工有针尖,针尖位于前针柄之中,前针柄与后针柄之间通过针体和连杆连接,前针柄和后针柄上分别设置有凹槽,凹槽的端部分别与连杆的端部连接。
所述的隐藏式一次性安全采血针,连杆的长度略大于针尖伸出前针柄左端的长度。
所述的隐藏缠绕毁型式一次性安全采血针,前针柄和后针柄中间的断面呈圆形。
本发明的一种隐藏缠绕毁型式一次性安全采血针具有以下突出的有益效果:1)结构简单,使用方便;2)采用隐藏针尖的方式对使用后的针尖进行隐藏毁型处理,具有很好的防二次污染和防意外伤害的有益效果。
附图说明
图1是采血针使用前的结构示意图;
图2是采血针的使用状态结构示意图;
图3是采血针使用后藏针的结构示意图;
图4是针杆毁型的实施方式图。
附图中的标记分别表示:针尖1、前针柄2、凹槽3、连杆4、针体5、后针柄6。
具体实施方式
下面结合附图对本发明的一种隐藏缠绕毁型式一次性安全采血针作进一步详细说明。
本发明的一种隐藏缠绕毁型式一次性安全采血针,其结构是由前针柄2、后针柄5和针体5组成,针体5通过注塑工艺设置在前针柄2和后针柄6之中,针体5的左端加工有针尖1,针尖1位于前针柄2之中,前针柄2与后针柄6之间通过针体5和连杆4连接,前针柄2和后针柄6上分别设置有凹槽3,凹槽3的端部分别与连杆4的端部连接。
所述的隐藏缠绕毁型式一次性安全采血针,连杆4的长度略大于针尖1伸出前针柄2的长度。
所述的隐藏缠绕毁型式一次性安全采血针,前针柄2和后针柄中间的断面呈圆形。
实施例
一种隐藏缠绕毁型式一次性安全采血针的使用方法如下:
1)同时相对推进前针柄和后针柄,针尖从前针柄的左端向外伸出,即可进行采血操作;
2)采血操作结束,将前针柄和后针柄相对折弯呈90度,针体将针尖拉进前针柄之中隐藏起来;
3)旋转前针柄将针体缠绕在前针柄的连杆上。
除本发明的说明书公开的技术特征外均为本专业技术人员的公知技术。
