Abstract
The utility model discloses a kind of vacuum test tube, belong to technical field of medical instruments.Its technical scheme is: a kind of vacuum test tube, comprise the rubber stopper one of vacuum tubings one, sealed vacuum body one opening, and be fixed on the pipe cap outside rubber stopper one, rubber stopper one is boss-shaped, first boss is provided with an annular groove, and the upper end of pipe cap embeds in described annular groove; The top of rubber stopper one arranges a concentric cylindrical projection, and be socketed a cylindric vacuum tubings two outside described column type projection, the upper end open of vacuum tubings two arranges rubber stopper two, and vacuum tubings two is made up of transparent material.The beneficial effects of the utility model are: overcome current blood taking tube and easily bring air into, and operator easily judge when insert a needle in blood taking tube, and meanwhile, when effectively ensure that centrifugal raising one's hat, pipe cap is deviate from rubber stopper simultaneously, and structure is simply easy to operation.
Description
Technical field
This utility model belongs to the technical field of medical apparatus and instruments, is specifically related to a kind of vacuum test tube.
Background technology
vacuum test tube is often used in current blood specimen collection, and it is formed primarily of vacuum tube and rubber stopper, during blood sampling in vacuum tube negative pressure effect under, blood flows via a conduit vacuum tubings inside, to be used by chemical examination.There is following shortcoming in the vacuum tube of current application: during blood sampling, air in conduit flowed into vacuum tube before blood, have impact on the purity of vacuum and blood sample, in the rubber stopper had at present, vacuum chamber is set, but operator still well cannot judge when insert a needle in blood taking tube.Vacuum test tube is when centrifugal de-lid in addition, is often deviate from by pipe cap, but rubber stopper is still stayed in vacuum test tube, affects work efficiency.
Utility model content
For solving the deficiency of above-mentioned prior art, the purpose of this utility model is to provide a kind of vacuum test tube, change the structure of rubber stopper, overcome current blood taking tube and easily bring air into, and operator easily judge when insert a needle in blood taking tube, meanwhile, when effectively ensure that centrifugal raising one's hat, pipe cap is deviate from rubber stopper simultaneously.
Invention thinking of the present utility model shows as:
A kind of vacuum test tube, comprise the rubber stopper 1 of vacuum tubings 1, sealed vacuum body 1 opening, and be fixed on the pipe cap 2 outside rubber stopper 1, described rubber stopper 1 is boss-shaped, first boss is provided with an annular groove 5, and the upper end of pipe cap 2 embeds in described annular groove 5;
The top of described rubber stopper 1 arranges a concentric cylindrical projection, and be socketed a cylindric vacuum tubings 24 outside described column type projection, the upper end open of described vacuum tubings 24 arranges rubber stopper 27, and described vacuum tubings 24 is made up of transparent material.
In described rubber stopper 1, vacuum chamber 6 is also set.
Described vacuum tubings 24 is made up of glass or clear hard plastics.
The beneficial effects of the utility model are: overcome current blood taking tube and easily bring air into, and operator easily judge when insert a needle in blood taking tube, and meanwhile, when effectively ensure that centrifugal raising one's hat, pipe cap is deviate from rubber stopper simultaneously, and structure is simply easy to operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Wherein, Reference numeral is: 1, vacuum tubings one; 2, pipe cap; 3, rubber stopper one; 4, vacuum tubings two; 5, annular groove; 6, vacuum chamber; 7, rubber stopper two.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Certainly, specific embodiment described herein only in order to explain this utility model, and is not used in restriction this utility model.
Embodiment 1
See Fig. 1, this utility model is a kind of vacuum test tube, comprise the rubber stopper 1 of vacuum tubings 1, sealed vacuum body 1 opening, and the pipe cap 2 be fixed on outside rubber stopper 1, rubber stopper 1 is boss-shaped, first boss is provided with an annular groove 5, and the upper end of pipe cap 2 embeds in described annular groove 5; The top of rubber stopper 1 arranges a concentric cylindrical projection, and be socketed a cylindric vacuum tubings 24 outside column type projection, the upper end open of vacuum tubings 24 arranges rubber stopper 27, and vacuum tubings 24 is made up of transparent material.
In rubber stopper 1, vacuum chamber 6 is also set.
Vacuum tubings 24 is made up of glass or clear hard plastics.
During use, pin enters in vacuum tubings 24 through rubber stopper 27 by staff, when observing needle point place and having blood to ooze, at once needle point is entered into vacuum tubings 1 through rubber stopper 1, starts to take a blood sample normally.Conveniently blood taking needle inserts rubber stopper 1 simultaneously, arranges vacuum chamber 6.After blood sampling terminates, vacuum tubings 24 and rubber stopper 27 can be taken off.
This utility model can pass through without the technical characteristic described or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; this utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
