Abstract
The utility model discloses a vacuum blood collection tube, which belongs to the field of the medical device. The vacuum blood collection tube aims to solve the problems that a failed vacuum blood collection tube is difficult to quickly distinguish due to the fact that no air pressure inspection device is arranged in the traditional vacuum blood collection tube, and the blood sample purity is affected as air in a conduit flows into the vacuum tube before blood. The vacuum blood collection tube disclosed by the utility model comprises a vacuum tube body, a tube cap and a rubber plug, wherein the opening of the vacuum tube body is sealed by the rubber plug; the tube cap is sheathed on the outer part of the rubber plug; the inner side wall on the lower part of the tube cap and the outer side wall of the vacuum tube body are tightly fit. The vacuum blood collection tube also comprises a vacuum cavity and an air bag, wherein the vacuum cavity is arranged in the rubber plug, and the conduit part of the air bag passes through the tube cap and the rubber plug and is communicated with the vacuum tube body.
Description
Technical field
This utility model relates to vacuum test tube, belongs to medical instruments field.
Background technology
Vacuum test tube is often used in blood specimen collection at present, and it is mainly made up of vacuum tube and rubber stopper, when blood sampling, connects human blood collection position by conduit, and in vacuum tube, under the effect of negative pressure, blood flows via a conduit vacuum body inside, to be used by chemical examination.Vacuum test tube is in dispatching from the factory, in body, be pumped into vacuum, and the principle of its blood sampling is also utilized the vacuum state in body exactly, blood is sucked in body, but existing vacuum test tube, once standing time is excessively of a specified duration, vacuum in its body can reduce, and even can approach atmospheric pressure, thereby causes vacuum blood collection tube failure, because existing vacuum test tube does not arrange pneumatic test device, thereby the vacuum test tube losing efficacy is difficult to distinguish fast.
In addition, for effective vacuum tube, air when blood sampling in conduit flowed into vacuum tube before blood, can affect the purity of blood sample.
Summary of the invention
This utility model object is, in order to solve existing vacuum test tube, pneumatic test device is not set, thereby the vacuum test tube losing efficacy is difficult to distinguish fast; Air in conduit flowed into vacuum tube before blood, had affected the problem of the purity of blood sample, and a kind of vacuum test tube is provided.
Vacuum test tube described in the utility model, it comprises vacuum body, pipe cap and rubber stopper, rubber stopper is by the opening sealing of vacuum body, pipe cap is socketed in rubber stopper outside, and the lateral wall of the medial wall of pipe cap bottom and vacuum body fits tightly, described vacuum test tube also comprises vacuum chamber and air bag, and vacuum chamber is set in rubber stopper, the conduit part of air bag is passed pipe cap and rubber stopper, and is communicated with vacuum body.
Advantage of the present utility model:
1, pipe cap is provided with an air bag, described air bag is connected with vacuum body, the blank pipe body of taking seriously is interior in the time of true hollow body, air bag is shrivelled, when the air pressure of taking seriously in blank pipe body approaches atmospheric pressure, air bag is full, can judge the atmospheric pressure state in body by the state of air bag, and can distinguish fast vacuum test tube and whether lost efficacy, very convenient.
2, in the rubber stopper of vacuum test tube described in the utility model, be provided with vacuum chamber, can be by the isolation of the air in conduit and blood sample, avoid miscellaneous bacteria in air to affect the purity of blood; In vacuum chamber, avoid air to enter in vacuum tube the air insulated in conduit, affect the negative pressure of vacuum tube.
Brief description of the drawings
Fig. 1 is the structural representation of vacuum test tube described in the utility model.
Detailed description of the invention
Detailed description of the invention one: present embodiment is described below in conjunction with Fig. 1, vacuum test tube described in present embodiment, it comprises vacuum body 1, pipe cap 2 and rubber stopper 3, rubber stopper 3 is by the opening sealing of vacuum body 1, pipe cap 2 is socketed in rubber stopper 3 outsides, and the medial wall of pipe cap 2 bottoms and the lateral wall of vacuum body 1 fit tightly, described vacuum test tube also comprises vacuum chamber 4 and air bag 5, the interior vacuum chamber 4 that arranges of rubber stopper 3, the conduit part of air bag 5 is passed pipe cap 2 and rubber stopper 3, and is communicated with vacuum body 1.
Blood taking tube is added a cover pipe cap 2, has improved the safety of blood sampling and verification.
In the time of blood sampling, blood taking needle first thrusts vacuum chamber 4, and by the Bas Discharged in blood taking needle, syringe needle flows out after blood, more further thrusts vacuum body 1, has ensured not to be brought into air in vacuum body 1, has ensured the purity of blood.
Detailed description of the invention two: present embodiment is described further embodiment one, it also comprises drainage screen 6, drainage screen 6 is arranged in vacuum body 1, and is positioned at vacuum body 1 the first half.
The foreign body such as blood clot, fiber protein yarn that drainage screen 6 suspends for holding back blood plasma or serum, and blood plasma or serum are passed through smoothly, to avoid stopping up the specimen needle of test instrunment, thereby simplify the operation that blood sample is checked.
Detailed description of the invention three: present embodiment is described further embodiment two, the aperture of drainage screen 6 is 0.1mm～0.4mm.
Detailed description of the invention four: present embodiment is described further embodiment two or three, the material of drainage screen 6 is nylon cloth, plastics, gauze or non-woven fabrics.
