Abstract
The invention relates to the technical field of vacuum blood collection technology, in particular to a three-way middle-layer extracting type blood serum separation pipe which is composed of a main pipe, an anti-splash cap, a rubber plug, a suction pipe, a concave space and a horizontal pipe. The main pipe is a vertical round pipe with the upper end and the lower end sealed, a crosswise-arranged horizontal pipe is arranged on the lateral wall of the upper half portion of the main pipe, the horizontal pipe is integrated with the main pipe, the shaft axis of the horizontal pipe is perpendicularly crossed with that of the main pipe, and the horizontal pipe is communicated with the main pipe. By means of the three-way middle-layer extracting type blood serum separation pipe, a sampling probe cannot be contacted with an impurity layer floating on the surface of the blood serum totally when extending into the blood serum separation pipe, so that the circumference that the sampling probe is blocked by impurities during the blood serum extracting process is avoided, and accuracy of the blood serum specimen detection results is improved.
Description
Technical field
The present invention relates to the vacuum blood drawing technique field, particularly relate to a kind of threeway middle level extraction-type serum separator tube.
Background technology
Existing serum separator tube is the upper end and opens wide the straight tube of lower end closed.After centrifugal treating that it is drawn blood, have one deck impurity and float on the serum surface.Because impurity floats on the serum surface; Extend into downwards from the mouth of pipe in the process of drawing serum the serum at sampling probe, syringe needle is in a single day from the floating layer of impurity process, and is blocked through regular meeting; Stop up even cause half of sampling probe, also can cause the blood preparation testing result inaccurate.This part impurity mainly is made up of the materials such as micromolecule micelle in the fiber protein yarn in the blood, grease and the separation gel.Because the chemical property and the physical property of said impurity have diversity, it is very difficult it fast, intactly being removed.
Summary of the invention
The present invention is for solving the deficiency of prior art; Provide a kind of medical personnel of confession to need not to remove the impurity on serum surface; Just can avoid sampling probe in extracting the serum process, contact fully, the serum purity that assurance is extracted, avoid the blocked threeway middle level extraction-type serum separator tube of syringe needle with impurity.
The scheme that solves technical matters of the present invention is:
Threeway middle level extraction-type serum separator tube is made up of the person in charge, splash cap, plug, SS, sinking space and transverse tube.Wherein, the person in charge is the pipe vertical, that upper and lower side all seals, and the transverse tube of a horizontally set is arranged on the sidewall of the person in charge's the first half, and the transverse tube and the person in charge are combined as a whole, and the transverse tube and the person in charge's axial line intersects vertically, and transverse tube communicates with the person in charge.Be plugged with plug in the external port of transverse tube, the periphery of plug is with splash cap.Have a SS on the end face of splash cap, the sinking space of a semisphere is arranged on the outer face of plug.
Before the use, in being responsible for, send into separation gel through the port of transverse tube earlier, pass through application of vacuum again; And cover plug and splash cap, make it to become finished product, after blood sampling finishes; The present invention is sent into hydro-extractor; And making the person in charge's axial line consistent with the centrifugal force direction of hydro-extractor, after the centrifugal end, the blood sample in the serum separator tube separates into impurity layer, serum, separation gel and haemocyte four parts from top to bottom successively; Use sampling probe to pass plug from the end cross of transverse tube this moment, can extract the pure serum that is positioned at the impurity layer below.
The sampling probe that said process adopted be State Intellectual Property Office on July 20th, 2011 disclosed application number be 201020665773.9 " a kind of sampling probe of analyser ".
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
Because the present invention can make sampling probe in stretching into the process of serum separator tube; Do not come in contact fully with the impurity layer that floats on the serum surface; But directly operate at the pure serum that is arranged in below the impurity layer; This is taken place by the situation that impurity stops up because of the process impurity layer in extracting the serum process with regard to effectively having been avoided existing sampling probe, has also improved the accuracy of blood preparation testing result simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. be responsible for 2. splash cap, 3. plugs, 4. SSs, 5. sinking space, 6. transverse tubes, 7. sampling probes, 8. impurity layers, 9. serum, 10. separation gels, 11. haemocytes
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
Threeway middle level extraction-type serum separator tube is made up of the person in charge 1, splash cap 2, plug 3, SS 4, sinking space 5 and transverse tube 6.Wherein, being responsible for 1 is the pipe vertical, that upper and lower side all seals, and is responsible for the transverse tube 6 that a horizontally set is arranged on the sidewall of 1 the first half, transverse tube 6 be responsible for 1 and be combined as a whole, and transverse tube 6 intersects vertically with the axial line of being responsible for 1, transverse tube 6 communicates with the person in charge 1.Be plugged with plug 3 in the external port of transverse tube 6, the periphery of plug 3 is with splash cap 2.Have a SS 4 on the end face of splash cap 2, the sinking space 5 of a semisphere is arranged on the outer face of plug 3.
Before the use, send into separation gel 10 through the port of transverse tube 6 to being responsible in 1 earlier, pass through application of vacuum again; And cover plug 3 and splash cap 2, make it to become finished product, after blood sampling finishes; The present invention is sent into hydro-extractor; And making the person in charge 1 axial line consistent with the centrifugal force direction of hydro-extractor, after the centrifugal end, the blood sample in the serum separator tube separates into impurity layer 8, serum 9, separation gel 10 and haemocyte 11 4 parts from top to bottom successively; Use sampling probe to pass plug 3 from the end cross of transverse tube 6 this moment, can extract the pure serum 9 that is positioned at impurity layer 8 belows.
The sampling probe that said process adopted be State Intellectual Property Office on July 20th, 2011 disclosed application number be 201020665773.9 " a kind of sampling probe of analyser ".
