The utility model relates to a sterile test tube cover, the upper end of the test tube cover is also connected with a ring for socketing finger. The preferred structure of the finger ring is a ring structure composed of a long strip fastener 21 connected by a detachable way from the head to the tail. A convex buckle is arranged at one end of the long strip fastener, and two to five connecting holes are arranged at the upper interval of the other end. The utility model has the following beneficial effects: 1. During the experiment, the operator's right little finger passes through the small ring, opens the lid, and hangs the lid on the little finger to avoid contamination caused by the contact between the test tube cover and the operating table or other devices. 2. The aseptic test tube cover is placed on the operator's right little finger, without affecting the operation of other fingers. The other fingers are operated experimentally, and the lid is quickly covered after operation. The aseptic operation process is simple, smooth and standardized. 3. The finger ring adopts a ring structure consisting of long strip fasteners, which can adjust the inner diameter according to the size of the operator's finger, making it more flexible and convenient to use.

无菌试管盖
本技术涉及一种试管盖,特别涉及一种无菌试管盖。
技术介绍
医院等单位的实验室工作中,需要经常使用到试管,有些实验要求在无菌的条件下操作。无菌操作时,需要遵循严格的无菌操作流程,避免实验器材与外界过多的接触。目前工作中试管规范的无菌操作方法是:右手小指拧开盖子,并夹在小指上,其他手指进行操作快速加样,然后重新盖上,避免试管内的试剂和样品长时间暴露造成污染。然而不熟练者常常夹不稳盖子,难以操作,为了避免手夹盖子造成掉落,有些试验人员把试管盖打开后,将试管盖置于台面上,试管盖因接触台面易造成二次污染;另外,操作加样过程中如有不慎,液体滴至台面上的试管盖上,也会造成污染,影响检测结果。目前公开的中国技术专利201220115046.4公开了一种管盖不易丢失或误盖的试管,包括试管本体、试管盖和连接套扣,其中连接套扣一端卡在试管盖的环形槽上,另一端卡在试管本体的环形槽上。该专利采用了连接套扣连接试管盖和试管本体,试验后可以很方便的把试管盖盖在试管本体上,防止了试管盖的误盖或丢失。该专利解决了试管盖易丢失的问题,但是还是存在试管盖打开后易被污染的问题,该专利在使用过 ...
