Abstract

本发明涉及一种用于翼针(2)的壳罩(1)，它包括一个横截面基本成U形地延伸的底盖(4)和一个伸展的顶盖(3)，这两个盖可以在装入翼针(2)的翼片后被封闭起来而形成一个壳体单元，导槽(9)由在壳体两侧空闲的、在这两个盖(3，4)的彼此相邻的垂直侧壁(6，7)之间的缝隙构成，在长期锁定位置(II)上，一个在前面的弹性锁定机构(17)从至少一个侧壁(6，7)起突入其中一个导槽(9)中。

Description

翼针的壳罩
技术领域
本发明涉及翼针的壳罩，它包括横截面大致呈U形地延伸的底盖和一个伸展的顶盖，所述的顶盖和底盖相互连接，并且在翼针的翼片被装到由这些盖在壳罩纵向上提供的且形成有一个前保持或锁定位置和一个后保持或锁定位置的两侧的导槽中后，这两个盖在相反端部上被封闭起来而形成壳体单元。
背景技术
为了采血而使用一根针，该针可通过连接软管和适配接头与采血小管相连，这样的针具有侧翼片。为了防止这样的针的使用者不小心损坏该针，这样的翼针有一个把针包围起来的壳罩。
这样的壳罩由EP0436646B1公开了。在这个实施方案中，该针通过与针相连的软管被拔出病人体外。为了保护使用者不会不希望地被针扎到，在一个受保护的位置上锁定抽缩回去的针。为固定该保护机构，一个锚定件被压到病人身体上。通过这种操作，减小了或者避免了使用者不小心被针扎到的危险。
在这个已知的实施方案中，翼针直接从病人的皮肤中被抽入壳罩的受保护位置中。
如果该锚定件被压到病人的皮肤上并同时用另一手拽软管，这种操作加重了病人的负担。可以使在某个时刻位于病人血管中的针移动或者能够运动起来。但这种运动带来疼痛。
发明内容
本发明的任务是使上述类型的壳罩更容易操作，从而当抽回翼针时不必须克服阻力并能将翼针抽回到在静脉外的长期锁定位置中。
利用独立权利要求的特征部分所述的特征来完成该任务。
在这里，根据一个实施例，顶盖比底盖窄，其中，这些导槽由在这些盖的相邻垂直侧壁之间的、垂直和水平的两侧空闲的缝隙构成。从盖的至少一个侧壁起，至少一个弹性锁定机构突入导槽里并且把翼针锁定在靠后的长期锁定位置上。
根据另一个实施例，顶盖和底盖可以对准。在完全成直线状的导槽的垂直缝隙中，一个设置在长期锁定位置之前的弹性锁定机构从盖的至少一个侧壁起突入导槽中。
翼针的前保持位置最好这样被锁定，即从顶盖或底盖的轮廓底面开始或从两个轮廓底面起突伸出保持机构，这些保持机构与翼针的中央部接触。这些保持机构例如可以成多个突起或多个接片或者一个接片的形状。
附图说明
从权利要求书和以下对附图所示的本发明实施例的说明中得到了本发明的其它优点和特征，其中：
图1以透视侧视图表示采血装置，它包括带有一壳罩的翼针；
图2表示沿图1的线X-X的截面；
图3是图1的采血装置的纵截面图。
具体实施方式
图1示出了一个很早就知道的包括所用翼针在内的采血装置中的一个容纳翼针2的壳罩1。该壳罩包括一个顶盖3和一个底盖4。在所示实施例中，顶盖3和底盖4一样宽。但顶盖3也可以比底盖4窄。
顶盖3例如通过一个薄膜铰链与底盖4相连。在装入翼针2后，顶盖3和底盖4例如通过钩接被锁定住。
另一种可能性在于，顶盖3和底盖4在两侧被锁定。该顶盖3或者底盖4的各自以垂直间距彼此邻接的侧壁6或7能够提供一个用于翼针翼片的导槽9的水平缝隙8。
如果顶盖3比底盖4窄，则形成一道水平缝隙8和一道垂直缝隙10，翼针2的翼片穿过该缝隙。
如果翼针2处于原始位置上即处于该装置来到使用者处的位置上，则翼针11被一个保护软管12套住。一个弹性的接片或突起13这样完成了翼针1的锁定，即该弹性的接片或突起与在翼针2中心部15上的一个凸起14有效连接。
在采血完成后，翼针2从病人静脉中被抽出。当抽回翼针2时，在翼针2中心部15上的凸起14在弹性的接片或突起13下方被抽走。在导槽9的一端上，翼片通过突入导槽9内的弹性锁定机构17被固定在一个长期锁定位置II上。弹性锁定机构17不产生阻力地被翼片压下去。

Claims (2)

1.一种用于翼针(2)的壳罩(1)，它包括一个横截面基本成U形地延伸的底盖(4)和一个伸展的顶盖(3)，这两个盖可以在装入翼针(2)的翼片后被封闭起来而形成一个壳体单元，其特征在于，用于翼片的导槽(9)由在壳体两侧空闲的、在这两个盖(3，4)的彼此相邻的垂直侧壁(6，7)之间的缝隙构成，一个安置在一个用于固定翼针(2)的长期锁定位置(II)之前的弹性锁定机构(17)从至少一个侧壁(6，7)起突入其中一个导槽(9)中。
2.如权利要求1所述的壳罩，其特征在于，该翼针(2)的一个前保持位置(I)具有至少一个从这些盖(3，4)的轮廓底面起突出的突起(13)，所述突起与在该翼针(2)的中央部上的凸起(14)有效连接。
