Abstract
The utility model belongs to the laboratory instrument technical field, particularly relating to a vacuum test tube. The vacuum test tube comprises a tube body; a fixed rubber plug and a movable rubber plug are arranged at the upper part of the tube body, wherein, the lower part of the movable rubber plug is positioned in the tube body and the upper part is positioned outside the tube body. When blood is sampled, the air in a puncture needle and a conduit behind the puncture needle is exhausted in advance, thereby the dimension of the dead space is effectively reduced and the air in the conduit is prevented from polluting the purity of the blood, meanwhile, the air exhaust in the conduit behind the puncture needle is reduced and the wastage of the negative pressure inside the test tube is also reduced.
Description
Technical field
This utility model relates to a kind of assay apparatus, is specially a kind of vacuum test tube.
Background technology
The general blood taking tube that adopts is drawn blood when taking a blood sample chemical examination in hospitals at different levels at present.Present vacuum test tube has the following disadvantages: 1, after length standing time, negative pressure deficiency in the pipe often causing the blood sampling failure, brings misery to the patient, has brought loss to hospital; 2, after the collection of use vacuum test tube finished, the vacuum test tube intracavity formed certain space, and this space medically is called " dead space ", had brought error for follow-up chemical examination, check, made result of laboratory test untrue.
The utility model content
For overcoming above-mentioned technical deficiency, this utility model provides a kind of vacuum test tube negative pressure deficiency of avoiding, and effectively reduces " dead space " volumetrical vacuum test tube.
For realizing above-mentioned technical purpose, this utility model is achieved through the following technical solutions: a kind of vacuum test tube, comprise body, body top is provided with fixedly plug, the body front end is provided with pipe cap, it is characterized in that fixedly plug and body upper end maintains a certain distance, and fixedly the top of plug is provided with a mobile plug, mobile plug bottom is positioned at body, and top is positioned at outside the body.When taking blood, blood taking needle is the saturating mobile plug of thorn earlier, and mobile plug upwards pulled out a part, gas in the blood taking needle rear duct is sucked mobile plug and the fixing space between the plug, the acupuncture fixing plug thoroughly of will taking a blood sample then, manage intravital negative pressure blood is sucked in the body, realize blood collection.
This utility model is discharged the gas in the blood taking needle rear duct, has effectively reduced the volume of " dead space ", and can avoid the pollution of the interior gas of conduit to blood purity; In advance the gas in the blood taking needle rear duct is discharged the loss that also can reduce the blood taking tube internal negative pressure simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1, fixing plug, 2, mobile plug, 3, pipe cap, 4, body.
The specific embodiment
Referring to accompanying drawing, body 4 adopts blood count standard test tube, and body 4 tops are provided with fixedly plug 1 and mobile plug 2, and mobile plug 2 tops are positioned at body 4 outsides, and body 4 upper ends are provided with pipe cap 3.During blood sampling, the saturating mobile plug 2 of blood sampling acupuncture, and upwards pull out a part, gas in the blood taking needle rear duct is sucked fixedly in the space between the plug 1 and mobile plug 2, then blood taking needle is further stung saturating fixedly plug 1, negative pressure in the body 4 sucks blood in the vacuum test tube, realizes blood collection.
