Description
Technical field
This utility model relates to a kind of stopper, in particular for airtight body fluid indwelling device test tube plug.
Background technology
The effect of test tube plug: on the one hand for by object in test tube or liquid retention in test tube, it is to avoid the thing in test tube
Body or liquid leakage；On the other hand play and take the connection with test tube of the liquid part and fix.
In prior art, generally by taking liquid part, liquid is added to test tube, the most again test tube plug is blocked examination
The opening of pipe.But during with stopper closure test tube opening, it some times happens that the situation that in test tube, liquid is scattered；Secondly
Taking liquid part with the plug engagement process of test tube plug, resistance is bigger, it has not been convenient to.
Thus how can ensure in liquid energy injecting tube smoothly, can stop again in test tube after liquid injects
Liquid leakage, and it is convenient to take the plug of liquid part, becomes the technical barrier that industry is urgently to be resolved hurrily.
Utility model content
Goal of the invention of the present utility model is, it is provided that one can stop liquid leakage in test tube, can ensure again liquid
Body flows into test tube smoothly by stopper, and little with taking when liquid part coordinates resistance in swapping process, and test tube plug easily.
Goal of the invention of the present utility model is achieved in that
A kind of airtight body fluid indwelling device test tube plug, described test tube plug includes for connecting fixing tubular upper；With
And for blocking the bottom of liquid, described bottom is made up of N number of occluding body, and the fixing end of occluding body is connected with described top, envelope
The movable part of stifled body can rotate relative to described fixing end, and described movable part is inwardly and downwardly extended by described fixing end and formed, institute
Stating top and described bottom to be integrated, occluding body fixes 70% that the thickness of end is not more than the sidewall thickness on described top.
Wherein, described occluding body can be lamellar.The number of occluding body can be 3,4,5,6,7,8,9,10 etc..
Further, the outside bending in bottom, medial wall the extension on described top are connected with described bottom, are positioned at junction
The outer rim maximum external diameter of bottom identical with described top external diameter.
May also be；Extend after the inside bending in bottom, lateral wall on described top and be connected with described bottom, be positioned at junction
The outer rim maximum internal diameter of bottom is identical with described upper inner diameter.
In such scheme, the inside bending in bottom, lateral wall on described top extends the joint face and described occluding body formed
Lateral surface intersects.Wherein, the outer rim maximum diameter of the described bottom being positioned at junction is less than the external profile diameter on top.
Or the outside bending in bottom, medial wall on described top extends the medial surface phase of joint face and the described occluding body formed
Hand over.Wherein, the outer rim maximum internal diameter of the described bottom being positioned at junction is more than the inner edge diameter on top.
In such scheme, the elongated surfaces of the joint face of the lateral wall on top and the lateral wall of bottom and the centrage of test tube plug
Angle is less than or equal to 90 ° more than or equal to 5 °.Preferably, the elongated surfaces of the joint face of the lateral surface of the lateral surface on top and bottom and examination
The centerlines of pipe close is less than or equal to 55 ° more than or equal to 35 °.
In such scheme, the thickness of the fixing end of described occluding body is more than or equal to 0.2mm and less than or equal to 0.6mm.Preferably,
The thickness of the fixing end of described occluding body is more than or equal to 0.25mm and less than or equal to 0.35mm.
Wherein, the thickness of described occluding body can be uniform, it is possible to is that self-retaining end is the most thinning to end.
The sidewall thickness on described top is more than the thickness of the fixing end of occluding body.
This utility model has the advantage that
This utility model is placed in the peristome of test tube, when taking liquid part (injecting liquid into the parts of test tube for auxiliary) and examination
When pipe assembly (after test tube coordinates with test tube plug) plug coordinates；
1, this utility model can stop liquid leakage in test tube at the peristome of test tube, can ensure that again liquid passes through test tube
Plug flows into test tube smoothly.
2, due at the maximum outer rim of the occluding body of bottom of the present utility model diameter less than the external diameter of junction on top,
I.e. the thickness of bottom occluding body is less than the wall thickness of tubular upper, so the resistance that occluding body is in downwardly and outwardly rotation process is relatively
Little so that the plug taking liquid part is also easier to.
