The vacuum blood collection tube comprises a vacuum tube body, a tube cap and a rubber plug, the rubber plug is used for sealing an opening of the vacuum tube body, the tube cap is sleeved outside the rubber plug, and the inner side wall of the lower portion of the tube cap is closely attached to the outer side wall of the vacuum tube body. The vacuum blood collection tube further comprises a vacuum cavity and a guide tube, the vacuum cavity is formed inside the rubber plug, the guide tube is arranged inside the vacuum tube body, one end of the guide tube is arranged on the lower portion of the rubber plug, and the other end of the guide tube extends to a tube wall position of 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 at present blood specimen collection, 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, it is inner that blood flows via a conduit the vacuum body in vacuum tube, to be used by chemical examination.There is following shortcoming in the vacuum tube of using at present: 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 sometimes also need gather with a plurality of vacuum tubes; Air during blood sampling in the conduit flowed into vacuum tube before blood, affected the purity of blood sample; Negative pressure is excessive or too smallly all can cause haemolysis in the vacuum tube.Negative pressure is relatively large, and excessive velocities is too quickly at the bottom of the blood inflow pipe, causes erythrocyte mutually to clash into, and causes erythrocyte fragmentation, sample hemolysis.
Summary of the invention
This utility model purpose is the problem that exists in order to solve existing vacuum test tube, and a kind of vacuum test tube is provided.
Vacuum test tube described in the utility model, vacuum body, pipe cap and rubber stopper, rubber stopper is with the opening sealing of vacuum body, pipe cap is socketed in the rubber stopper outside, and the lateral wall of the medial wall of pipe cap bottom and vacuum body fits tightly, and described vacuum test tube also comprises vacuum chamber and mozzle, vacuum chamber is set in the rubber stopper, be provided with mozzle in the vacuum body, an end of mozzle is arranged on the below of rubber stopper, and the other end extends to the tube wall place of vacuum body.
Advantage of the present utility model:
1, is provided with vacuum chamber in the rubber stopper of vacuum test tube described in the utility model, can with the air in the conduit and blood sample isolation, avoids the interior miscellaneous bacteria of air to affect the purity of blood; In vacuum chamber, avoid air to enter in the vacuum tube air insulated in the conduit, affect the negative pressure of vacuum tube;
2, vacuum test tube described in the utility model is provided with mozzle, does not need during blood sampling body is tilted, and blood also flows down along tube wall by mozzle; Because the bore of mozzle is reduced downwards gradually by the plug of the mouth of pipe, heavy caliber can avoid the interior space of mozzle narrow, avoid puncture needle to penetrate mozzle, small-borely be arranged at the tube wall place of vacuum tube and be provided with the tip at the mouth of pipe, make blood flow to the tube wall place and flow down along tube wall along mozzle smoothly, prevent erythrocyte directly bump cause and break, avoid haemolysis to occur.
Description of drawings
Fig. 1 is the structural representation of vacuum test tube described in the utility model.
The specific embodiment
The specific embodiment one: present embodiment is described below in conjunction with Fig. 1, the described vacuum test tube of present embodiment, vacuum body 1, pipe cap 2 and rubber stopper 3, rubber stopper 3 is with 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 mozzle 5, the rubber stopper 3 interior vacuum chambers 4 that arrange, be provided with mozzle 5 in the vacuum body 1, one end of mozzle 5 is arranged on the below of rubber stopper 3, and the other end extends to the tube wall place of vacuum body 1.
Blood taking tube is added a cover pipe cap 2, has improved the safety of blood sampling and verification.
The specific embodiment two: present embodiment is described further embodiment one, and the bore of mozzle 5 is from reducing gradually to an end that is positioned at vacuum tube body 1 tube wall near rubber stopper 3 one ends.
The specific embodiment three: present embodiment is described further embodiment one or two, and it also comprises mozzle tip 6, and the end opening place that mozzle 5 is positioned at vacuum body 1 tube wall place is provided with a mozzle tip 6 that is adjacent to tube wall.
