Abstract

本发明涉及一种医用安全器械,该医用安全器械安装了一个采集血样或注射用的针头,在这种类型的器械中,装有针管的空心针头被固定在可弹性变形的支承件上,该支承件安装在刚体上,该刚体在适合于盖住针头的U形截面的保护套中延伸,该针头仍可利用支承件的瞬时弹性变形与所述保护套分开,其特征在于,它包括适合于防止支承件任何偶然变形的可伸缩的锁紧机构。

Description

装有注射或采集血样用针头的医用器械
本发明涉及一种装有注射或采集血样用针头、特别是静脉内使用的那一类针头的医用器械，该医用器械被设置成在使用后避免针头与操作人员任何偶然的接触，以便消除任何污染的危险。
美国专利5 102 397号(BRUNET)示出一个这种类型的器械，在附图的图1中重新列入了该类型器械的一般配置。装有针管2的空心针头1固定在支承件3上，该支承件3用可弹性变形的材料制成，并且该支承件3在与针头对置处啮合到一个刚体4中，该刚体4向前延伸到一个向下开口的U形截面的保护套中。在如图所示的静止位置，针头1安置在保护套5的内部，而不会受到任何偶然接触的危险，并且它足以使希望继续进行注射或采集血样的操作人员对支承件3施加压力(箭头6)以使针头1伸出，操作人员一放松他(她)的压力，所述针头就弹性地重新回到开始的内缩位置。
该器械提供的安全性是很好的，尽管操作很简单，却不需要另外的手势来使该组件重新回到保护位置。但是，当该器械用过之后放在工作台上或装入软的废物真空袋中时，万一任何物体同弹性支承件3接触而使针头与保护套不适当地分开，则有由针头1引起的刺伤或偶然伤害的危险。
本发明的目的是提供一种上述美国专利中所说明的那种类型的医用安全器械，对该器械加以改进，以避免任何针头不适当地分开的危险。
为此，本发明基本上在于给该器械的刚体设置适合于防止针头支承件偶然弹性变形的可伸缩的锁紧机构。
根据具体情况，这些可伸缩的锁紧机构可以采取防止该支承件接触任何外部的可伸缩盖的形式，或是采取移动式止动销或制动块的形式。
在参照附图阅读下面的说明时，将更容易理解本发明，附图中：
图1为如上所述的说明相应于美国专利5 102 397号的先有技术的轴向截面图。
图2示出按照本发明的一种医用安全器械的透视图。
图3为该器械处于使用位置(注射或采集血样)时的轴向截面图。
图4示出一个改型的实施例。
图5示出本发明的另一个实施例。
图6和7为说明图5中器械操作功能和使用的沿着VI-VI线(图5)的横截面图。
再参看附图，图2和3示出一个装有针头1和后部针管2的可弹性变形的支承件3，以及一个向前延伸到保护套5中的刚体4，在样式上它们全都基本上和图1中的先有技术相同。
按照本发明，该刚性体4还包括一个与保护套5相似的U形截面的刚性盖7。该刚性盖7用一个拱形轮廓的刚性元件8固定，该刚性元件8朝后通过一个能形成绞接的变薄的区段9连接刚体4。
很容易理解，盖7和元件8盖住了支承件3，因此保护支承件3免受任何偶然的接触。为了进行注射，操作人员必须向上收起盖7(图3中的箭头10)，以便可以接近支承件3，然后可向下推支承件3以针头1伸出。在打针结束时，支承件3和盖7在它们的弹性作用下自动回到按照图2的保护位置。
图4中的改型实施例与图2和图3实施例的不同之处只是用盖7固定的拱形元件8不再直接接合刚体4，但仍然通过一个铰接件9连接保护套5。
在图5-7的实施例中，可弹性变形的支承件3由用针头1和针管2进行固定的平叶片3构成。该平叶片3用制动块11横向固定，在制动块11的下面，刚体4有一个伸出的底脚4a。在静止位置时(图6)，该制动块11垂直延伸并且它的端部倚靠在底脚4a上，同时防止平叶片3的任何向下变形。当使用注射器时，制动块11必须按图7中所示的方式操作；该制动块11的沿横向退回能使支承针头的平叶片3变形并使针头1暴露出，组件3-11弹性回到开始的位置，起到使针头1在保护套5下的保护位置中被锁定的作用。
在保证绝对安全时，操作仍然很简单，只涉及惯用的手势。
