The utility model discloses can block in the test tube that liquid or object leak outward, again can be to object in the test tube or liquid inspection under the condition of not taking off test tube stopper, and when taking out perfusion equipment and when taking out the check out test set, reduce and carry out the test tube with object in the test tube or liquid and cause pollution, the convenient advantage of easy operation outward.
Description
Technical field
The utility model relates to a kind of stopper, especially the stopper of the airtight body fluid indwelling device of portable disposable.
Background technology
Test tube plug is used for object in test tube or liquid retention in test tube, avoids the object in test tube or liquid leakage.In prior art, test tube plug mostly is solid.
In prior art, during with perfusion equipment to test tube filling liquid, be not connected and fixed parts because perfusion equipment coordinates with test tube, perfusion equipment and test tube easily come off mutually, need two people to assist just can guarantee during operation, very inconvenient.
After test tube filling liquid completes, block with the opening portion of test tube plug by test tube, once after test tube plug blocks the openend of test tube, as needed again to perfusion fluid in test tube or to invisible spectro object or liquid detecting, need could implement after test tube plug taking-up, cause operational loaded down with trivial details and inconvenient.
Thus perfusion equipment how is made easily to be connected and fixed test tube filling liquid to when, and simple operation, add while extracting perfusion equipment after filling liquid and can realize shutoff, and can check liquid in test tube or object without the need to taking off test tube plug again, become the technical barrier that industry is urgently to be resolved hurrily.
Utility model content
Goal of the invention of the present utility model is, providing one can stop liquid or object in test tube and leaks outside, when not taking off test tube plug, can check the object in test tube or liquid again; And when taking out perfusion equipment and when taking out checkout equipment, reduce object in test tube or liquid to carry out outside test tube polluting, simple and convenient test tube plug.
Goal of the invention of the present utility model is achieved in that
A kind of portable disposable airtight body fluid indwelling device test tube plug, comprise body, described body is provided with upper surface, lower surface and connects the side of described upper surface and described lower surface, described body is provided with axial passage, described passage is provided with opening first on described upper surface, described passage is provided with opening second on described lower surface, and the area of described opening second is less than the area of described opening first.Test tube plug is made up of elastomer, as silica gel, rubber, TPU, TPE etc.Opening first on upper surface and passage thereof are used for the fixing of the counterpart coordinated with test tube plug and seal, generally, the counterpart (as perfusion equipment) of test tube plug is more than or equal to 30 ㎜ 2 with the area of the cooperation place of the opening first of test tube plug and is less than 112 ㎜ 2, preferred value is 35 ㎜ 2,45 ㎜ 2,65 ㎜ 2,80 ㎜ 2,95 ㎜ 2; The counterpart of test tube plug coordinates with the connection of test tube to can be to plug and coordinates.Opening second is used for also having while liquid guide flow and effectively can reduces liquid in pipe and flow out from opening second, because liquid has the characteristic easily forming liquid film characteristic and negative pressure at the small-bore mouth of pipe, the probability that the less liquid in pipe of opening second area outflows through opening second is lower.When opening second area is less, opening second areal extent is for being more than or equal to 2 ㎜ 2 and being less than 50 ㎜ 2, and preferred value is 5 ㎜ 2,10 ㎜ 2,15 ㎜ 2,20 ㎜ 2,25 ㎜ 2,30 ㎜ 2,35 ㎜ 2,40 ㎜ 2, effectively can reduce in vitro liquid and flow out through opening second.When opening second area is between 3 ㎜ 2 to 10 ㎜ 2, not only can improve effect that liquid in pipe do not outflow but also can ensure that liquid was smooth and easy from opening second inflow pipe, in addition, that also the wall thickness of the body around opening second can be prepared is thinner, if the wall thickness of the body around opening second is at 0.3mm to 0.6 ㎜, when the counterpart (as perfusion equipment) being convenient to test tube plug coordinates with test tube plug, more easily just opening ethylene is opened and is made in the smooth and easy inflow pipe of liquid.
Further, described passage is inverted round table-like; Or the conduit wall of described passage is by big column side, small column side, and the anchor ring connecting described big column side and small column side is formed, and wherein, described anchor ring can be plane, can be also curved surface, as arc surface etc.; It can also be frustum cone side etc.
Further, the lateral surface of described body is provided with projection.The number of described projection can be 1,2 etc., and described projection can be positioned at upper end, also can be to be positioned at middle part.Described projection can be the convex shoulder of ring-type, also can be that point-like is protruding, can also be L shape annulus, form annular groove between described L shape annulus and the lateral surface of described body.
Further, the conduit wall of described passage is provided with projection.
The utility model be used for test tube with the use of, be generally positioned at the openend of test tube, the utility model has the following advantages:
1) after blocking test tube openend with the utility model, perfusion equipment coordinates perfusion fluid by the utility model with test tube, do not need extra to be connected and fixed parts because perfusion equipment coordinates with test tube, the bottom of perfusion equipment only need be fixed with passage fit inside of the present utility model, therefore simple and convenient, only need one man operation.
2), after the utility model blocks test tube opening portion, after removing perfusion equipment, the liquid in test tube still can be held in test tube official jargon by the utility model effectively.
3) when perfusion equipment being removed, because the utility model is provided with passage, can by perfusion equipment bottom by the liquid holdup in test tube in passage, effectively reduce the liquid contamination test tube taken out of.
4) be provided with projection in passage of the present utility model, namely on the madial wall of described body, be provided with projection, strengthen the sealing that perfusion equipment coordinates with the utility model on the one hand, add the firmness that perfusion equipment coordinates with test tube plug on the other hand.
