Abstract
The utility model discloses a vacuum blood collection tube which comprises a tube cap, a vacuum tube body and a rubber plug, wherein, a vacuum cavity is formed in the rubber plug; during blood collection, a catheter connected with the blood collection needle of the vacuum blood collection tube is firstly inserted into the vacuum cavity in the rubber plug; under the action of pressure difference, air in the catheter flows into the vacuum cavity; and when blood arrives, the blood collection needle is further inserted into the vacuum tube body, so that the blood flows into the vacuum blood collection tube. By using the vacuum blood collection tube to collect blood, air in the catheter can be isolated from blood samples, so as to prevent mixed bacteria in the air from influencing the purity of the blood; and furthermore, the air in the catheter can be isolated in the vacuum cavity, so as to prevent the air from entering the vacuum body and influencing the negative pressure thereof.
Description
Technical field
This utility model relates to medical instruments field, is specially a kind of vacuum test tube.
Background technology
Vacuum test tube is often used in blood specimen collection at present, and it mainly is made of vacuum tube and rubber stopper, connects the human blood collection position by conduit during blood sampling, and under the effect of negative pressure, blood flows via a conduit vacuum body inside in vacuum tube, to be used by chemical examination.There is following shortcoming in the vacuum tube of present application: shelve for a long time and can reduce negative pressure in the vacuum tube, can not obtain the blood sample of institute's expense, even also need sometimes gather with a plurality of vacuum tubes; During secondly for blood sampling, the air in the conduit flowed into vacuum tube before blood, influenced the purity of blood sample.
The utility model content
For solving the problems of the technologies described above, it is a kind of simple in structure that this utility model provides, and avoid the interior air of conduit to mix with blood sample, and negative pressure keeps vacuum test tube preferably in the vacuum tube.
For realizing above-mentioned technical purpose, this utility model is achieved through the following technical solutions: a kind of vacuum test tube, constitute by pipe cap, vacuum body, rubber stopper, rubber stopper seal vacuum body, guarantee the intravital negative pressure of vacuum tube, pipe cap is used for fixing, the proof rubber plug, it is characterized in that having in the rubber stopper vacuum chamber.During blood sampling, the blood taking needle that conduit is connected vacuum test tube at first inserts in the vacuum chamber in the rubber stopper, under action of pressure, air in the conduit flows in the vacuum chamber, when treating that blood reaches blood taking needle, blood taking needle is further inserted in the vacuum body, make blood flow into vacuum test tube.
This utility model is compared with present technology, has following beneficial effect: be provided with vacuum chamber in the rubber stopper, air in the conduit and blood sample can be isolated, avoid the interior assorted bacterium of air to influence the purity of blood, secondly with the air insulated in the conduit in vacuum chamber, avoid influencing the negative pressure of vacuum tube in the air admission vacuum tube.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of vacuum test tube is made of pipe cap 2, vacuum body 4, rubber stopper 3, and rubber stopper 3 sealed vacuum bodys 4 guarantee the negative pressure in the vacuum body 4, and pipe cap 2 is used for fixing, proof rubber plug 3, has a vacuum chamber 1 in the rubber stopper 3.During blood sampling, the blood taking needle that conduit is connected vacuum test tube at first inserts in the vacuum chamber 1 in the rubber stopper 3, under action of pressure, air in the conduit flows into vacuum chamber interior 1, when treating that blood reaches blood taking needle, blood taking needle is further inserted in the vacuum body 4, make blood flow into vacuum test tube.
Claims (1)
1. a vacuum test tube is made of pipe cap, vacuum body, rubber stopper, and rubber stopper seal vacuum body guarantees the intravital negative pressure of vacuum tube, and pipe cap is used for fixing, the proof rubber plug, it is characterized in that having in the rubber stopper vacuum chamber.
