Abstract

一种自收缩皮下注射针头的保护套，其作用在于 注射前后，使用注射的针头是被隐藏和保护起来，其 基本特征是一圆柱管体两端开口，并至少在内部含有 一最小宽度和厚度的环形凸肩，用来卡住持针器，该 管体还有一位于持针器的端部凸肩和管体内的凸肩 间的伸缩弹簧，一旦注射器作完一次注射，弹簧即推 持针器进入管体并隐藏针头，在该管体上开有细长侧 窗口，当使用时管体和注射器两者同时握住。

Description

本发明由一种自收缩皮下注射针头的保护套组成，其目的在于提供市场和公众一种新的产品，它在使用前后都能防止该针头与任何其它物品接触，还可以防止因与注射器脱开而针头落在地上产生任何间外的札刺。
这种保护套设计成任选地具有针管内带有针头的持针器，它有一个中空的内圆柱体，具有细长的侧视窗和一向内凸出的小环形台肩，该台肩处在圆柱体长度中央的前部，这个凸肩的宽度很小只作为持针器的支座（amchorage），在持针器的末端依靠辅助槽使持针器保持在位置上，即针头处在其相对另一端冒出，还设有一位于环形台肩前方和圆柱体前端之间的一内伸缩弹簧。
对在保护套台肩上持针器的支座只要施加很小的推力就足于推动它，因此在需要的时刻推进持针器并使针头冒出，除了叙述过的功能外，由于前面提到的伸缩弹簧的作用持针器又立即被推回，保护套显然允许相应的注射器插入，沿保护套轴向地移动直到注射器端部碰到持针器，在这时如果注射器继续推进，则持针器将自行脱开，如上所述，持针器向外移动。因此，针头冒出以备使用，首先通过注射器的活塞把药水吸入，然后再注射药水，一旦此操作完成，注射器就被推回，持针器由于弹簧的作用也就被推回到针头也就随之隐藏起来。
设置在保护套上的细长侧窗口的作用是能同时抓住保持套和在保护套内的注射器。
为了更好地了解本发明的特点，参照附图作为说明书的组成部分详细描述如下，下述部件在附图里示出：
图1示出保护套与已缩回的持针器和隐藏的针头在一起的纵向剖面图。
图2示出在同一保护套内持针器推到位并显露针头的纵向剖面图。
图3示出使用后持针器和针头的隐藏位置的纵向剖面图。
附图内下述零件的标号为：
1.——保护套体
2.——保护套体（1）的颈端
3.——保护套体（1）的内环形凸肩
4.——保护套体（1）的侧窗口
5.——伸缩弹簧
6.——持针器
7.——针头
8.——持针器（6）的凸肩
从附图内可见，此处的保护套系一圆柱体（1），中空并在两端开口，对于前端的端头显得缩小（2）。
在保护套体（1）内表示出有一最小厚度和宽度的环形凸肩（3），它位于保护套全长中央的稍前部，从凸肩区（3）的向后部分示有几个细长的窗口（4），有一伸缩弹簧（5）处在环形凸肩（3）和颈端（2）之间。
因此保护套能与装在其内部的持针器（6）和它自身的针头（7）一起销售，持针器（6）在它的后端含有一个环形凸肩（8）使它靠着保护套环形凸肩（3），以致持针器（6）将与针头（7）阻留在此位置，如图1所示完全隐藏并保护起来。
当使用时，注射器从轴向插进保护套（1）的后端直至该注射器装在持针器（6）内的接口端上，然后，如果注射器继续前推，持针器（6）的凸肩（8）将越过保护套的凸肩（3），注射器和针头（7）两者如图2所示，被推进克服了弹簧（5）阻力直至针头冒出。
在该位置所注射的药水可由注射器活塞吸入，此操作可以没有注射器或持针器（6）的往后移动，因为操作者在握住保护套1的时候会通过窗口（4）同时持住注射器。
一旦药水已经注入，注射器就推回并从保护套中抽出。与此同时，弹簧（5）将使持针器（6）退回并因此使针头（7）再隐藏起来，当持针器端部凸肩（8）被置入到属于保护套凸肩（3）的下台阶的时候，持针器（6）就处于夹持状态。
