Abstract
The invention relates to the technical field of vacuum blood collection, in particular to a serum separating tube with a selective sucking function. The serum separating tube with the selective sucking function consists of a conduit sealing plug, a splash-proof cap, a rubber plug, a conduit, a main tube and a bottom plug, wherein the cylindrical bottom plug is adhered at the center of the inner bottom of the main tube; the rubber plug is plugged into an upper end opening of the main tube; a vertical through hole is formed in the middle part of the rubber plug; the upper end of the conduit is positioned inside the vertical through hole of the rubber plug; and the lower end of the conduit is sleeved at the upper end of the bottom plug and is in interference fit with the bottom plug. The serum separating tube with the selective sucking function can directly sample serum and blood cells; and compared with the conventional ordinary separating tube, the serum separating tube with the selective sucking function has dual functions and brings conveniences for sampling.
Description
Technical field
The present invention relates to vacuum blood drawing technique field, particularly relate to a kind of serum separator tube with selectivity extract function.
Background technology
Existing serum separator tube, after taking a blood sample and separating by hydro-extractor, blood sample and separation gel are divided into successively from top to bottom serum, separation gel and three layers of haemocyte in pipe.In procedure, sometimes need to take serum, and sometimes need to take haemocyte analysis.Serum, due in ground floor, can directly stretch into sampling probe wherein and extract.But the bottom of haemocyte in serum separator tube, if arrive again in haemocyte after adopting sampling probe through serum, separation gel, sampling needle will inevitably be brought into the molecule of a small amount of serum and separation gel in haemocyte, has affected so undoubtedly the accuracy of haemocyte chemical examination.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides a kind of serum separator tube with selectivity extract function that directly extracts selectively haemocyte or serum and not disturbed by other materials for medical personnel.
The scheme that solves the technology of the present invention problem is:
There is the serum separator tube of selectivity extract function, formed by conduit sealing-plug, splash cap, plug, conduit, supervisor and bottom plug.Wherein, supervisor is that upper end opens wide, the glass tube of lower end closed, and the central authorities of supervisor's inner bottom surface are bonded with a columniform bottom plug, bottom plug and supervisor's coaxial inner conductor.
In supervisor's upper port, be plugged with plug, there is a vertical through holes at the middle part of plug.Conduit is a straight tube, and in the vertical through holes of the upper end of conduit in described plug, the outer wall of conduit upper end and the inwall of described vertical through holes are bonding is an entirety.The lower end of conduit is placed on the upper end of described bottom plug and becomes interference fit relation with bottom plug.The top of described vertical through holes is plugged with conduit sealing-plug, becomes interference fit relation in the upper port of the lower end of conduit sealing-plug in described conduit and with conduit.The degree of depth in described bottom plug insertion conduit is greater than described plug and inserts in the degree of depth in supervisor.The vertical extension of described bottom plug is 1/6 of supervisor's vertical extension---1/4.
The outside cover of described plug has splash cap.The material of conduit sealing-plug, plug, bottom plug is butyl rubber.
In blood collection procedure, blood taking needle must through plug and be inserted into the outer wall of conduit and supervisor's inwall annular space in.Until blood sampling with after centrifuging completes, if desired take serum, directly sampling probe is inserted into conduit and be responsible between annular space in can extract serum; If desired take haemocyte, first the assembly of conduit sealing-plug, splash cap, plug, conduit is upwards extracted from the suitable for reading of supervisor, lower end and the bottom plug of conduit are departed from, then conduit sealing-plug is upwards extracted from the top of plug, now because the inside of conduit and supervisor's inside communicate, and conduit and supervisor all communicate with atmospheric pressure, therefore haemocyte lower port from conduit under Action of Gravity Field upwards pours in conduit, now, directly use sampling probe to extend into from the vertical through holes of plug and in conduit, just can be drawn into pure haemocyte.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. owing to adopting the present invention, both can directly extract serum, can directly extract again haemocyte, compared with existing common separation pipe, there is double effects, for sampling work provides convenience.
2. because the present invention can, for lab technician in the process of taking haemocyte, avoid the interference of serum and separation gel, directly sampling probe is inserted in haemocyte, the haemocyte obtaining like this has higher purity, has greatly improved the accuracy of haemocyte chemical examination.
3. production of the present invention, can utilize existing general blood collection tube to transform, and again produces without a complete set.So just utilize existing resource, saved production cost.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
There is the serum separator tube of selectivity extract function, formed by conduit sealing-plug 1, splash cap 2, plug 3, conduit 4, supervisor 5 and bottom plug 6.Wherein, supervisor 5 is that upper end opens wide, the glass tube of lower end closed, and the central authorities of supervisor 5 inner bottom surface are bonded with a columniform bottom plug 6, bottom plug 6 and supervisor's 5 coaxial inner conductors.
In supervisor 5 upper port, be plugged with plug 3, there is a vertical through holes at the middle part of plug 3.Conduit 4 is straight tubes, and in the vertical through holes of the upper end of conduit 4 in described plug 3, the outer wall of conduit 4 upper ends and the inwall of described vertical through holes are bonding is an entirety.The lower end of conduit 4 be placed on the upper end of described bottom plug 6 and with 6 one-tenth interference fit relations of bottom plug.The top of described vertical through holes is plugged with conduit sealing-plug 1, in the upper port of the lower end of conduit sealing-plug 1 in described conduit 4 and with 4 one-tenth interference fit relations of conduit.Described bottom plug 6 inserts the degree of depth in conduit 4 and is greater than described plug 3 and inserts in the degree of depth in supervisor 5.The vertical extension of described bottom plug 6 is 1/6 of supervisor's 5 vertical extension---1/4.
The outside cover of described plug 3 has splash cap 2.The material of conduit sealing-plug 1, plug 3, bottom plug 6 is butyl rubber.
In blood collection procedure, blood taking needle must and be inserted in the annular space outer wall and supervisor's inwall of 5 of conduit 4 through plug 3.Until blood sampling with after centrifuging completes, if desired take serum 7, directly sampling probe be inserted into conduit 4 and be responsible in the annular space between 5 and can extract serum, if desired take haemocyte, first by conduit sealing-plug 1, splash cap 2, plug 3, the assembly of conduit 4 is from being responsible for 5 suitable for readingly upwards extract, lower end and the bottom plug 6 of conduit 4 are departed from, then conduit sealing-plug 1 is upwards extracted from the top of plug 3, now because the inside of conduit 4 communicates with supervisor 5 inside, and conduit 4 and supervisor 5 all communicate with atmospheric pressure, therefore haemocyte 9 upwards pours in conduit 4 from the lower port of conduit 4 under Action of Gravity Field, now, directly use sampling probe to extend into from the vertical through holes of plug 3 and in conduit 4, just can be drawn into pure haemocyte 9.
