The existing process that blood sample in the vacuum blood sedimentation tube is taken out all is that plastics splash cap and the plug of vacuum blood sedimentation tube are pulled up from the test tube mouth, then entry needle is stretched into the liquid from the mouth of pipe and extracts.Owing to having certain negative pressure in the blood sedimentation tube, pull away the moment of test tube at plug, ambient atmos pours in the pipe, can cause that the blood in the pipe outwards splashes.Although existing vacuum blood sedimentation tube has been equipped with splash cap in its rubber stopper outside, this can not stop blood fully and contact with the operator, because if the splashing amount of blood is larger, still can flow out along the inwall lower edge of splash cap, therefore existing laboratory sampling mode still exists certain danger.Therefore the medical personnel is in the process that plug is pulled up, and always very slow and meticulous, this has also reduced the work efficiency of blood sample analysis.
For addressing the above problem, to be 201020665773.9 " a kind of sampling probe of analyser " offer groove more than two at the sidewall of syringe needle to application number, to obtain the balance of blood sedimentation tube external and internal pressure, but the laboratory personnel finds in life-time service, pass in the process of plug at this syringe needle, the groove on the sidewall of syringe needle still can be by the plug shutoff.Trace it to its cause, as the optimal material of making the test tube plug because of butyl rubber, it possesses good elasticity and air-tightness, even trickle slit on the syringe needle, the elasticity shutoff is carried out by butyl rubber in the capital, so technique scheme can not really play the effect of balance blood sedimentation tube inner and outer air pressure.
The utility model content
This utility model is for solving the deficiencies in the prior art, provide a kind of medical personnel of supplying under the prerequisite of not pulling up plug, only just can directly from the vacuum blood sedimentation tube, take a blood sample with the normal injection pin, guarantee the sleeve pipe extraction-type splashproof vacuum blood sedimentation tube of medical personnel's safety fully.
The scheme that solves this utility model technical problem is:
Sleeve pipe extraction-type splashproof vacuum blood sedimentation tube is made of suction socket, splash cap, plug, sinking space, broken plug tube, test tube, taper knob and pushing ram.Splash cap is the cylindrical plastic housing that the lower end opens wide, there is a suction socket upper end.The outline of plug is cylindrical, the sinking space that the upper surface of plug has is one columniform, the upper end opens wide, plug is in the first half of splash cap, and become the interference fit relation with the inwall of splash cap, the lower end plug of plug becomes interference fit relation in the upper end of test tube and with the inwall suitable for reading of test tube, the inwall of the Lower Half of splash cap and test tube outer wall suitable for reading becomes clearance fit relationship.
Be provided with a broken plug tube in described sinking space, broken plug tube is that a upper and lower side is all opened wide, material is the pipe of rigid plastics.The interior diameter of broken plug tube is not less than 2mm greater than the overall diameter of sampling probe and the difference of the two, and the lower end of broken plug tube is an acute angle, and the upper end of broken plug tube is to be holistic ring bodies with breaking plug tube, and described ring bodies becomes clearance fit relationship with the medial wall of sinking space.
Pushing ram is that a root timber matter is the cylinder of rigid plastics, and the lower end of pushing ram can be passed from described suction socket and become clearance fit relationship with described suction socket.The upper end cover of pushing ram has the taper knob of quality of rubber materials.
When from the vacuum blood sedimentation tube, extracting blood sample, first suction socket is passed in the lower end of pushing ram and be inserted in the sinking space, continue to exert oneself downwards, promote broken plug tube and move downward and the bottom of plug is pierced through.Pushing ram is extracted out from sinking space and suction socket, at last sampling probe is passed through successively the inside of suction socket, sinking space and broken plug tube from top to bottom, then be inserted in the blood sample.Because the interior diameter of broken plug tube is not less than 2mm greater than the overall diameter of sampling probe and the difference of the two, so enough spaces are arranged with balance outer air pressure in vitro between the inwall of sampling probe and broken plug tube, by the suction of sampling probe, can smoothly blood sample be extracted out.
Adopt such scheme, compared with prior art, the utlity model has following marked improvement:
Because having adopted from suction socket, this utility model will break the mode that plug tube advances, the inner air and outer air of blood sedimentation tube is communicated, in this process since pushing ram in the stopping of suction socket place, in the moment that the blood sedimentation tube inner and outer air pressure communicates, blood sample can't be by broken plug tube and suction socket splash out.Therefore this utility model is under very safe condition, for directly carrying out the safety sampling from blood sedimentation tube, common sampling probe created necessary condition, so not only having omitted needs to extract this step that wastes time and energy of plug in the conventional art, make more convenient to operate, improved work efficiency; The more important thing is, the blood when having stopped to extract plug in the pipe splashes and to the danger that the medical worker causes, makes the operation safe of blood sample analysis reliable.
