Abstract
The utility model relates to the technical field of vacuum blood sampling, in particular to a bidirectional blood serum separation tube. The bidirectional blood serum separation tube is composed 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 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 bidirectional blood serum separation tube can be used for directly sampling serum and blood cells, and compared with a conventional ordinary separation tube, the bidirectional blood serum separation tube has dual functions and brings conveniences for sampling.
Description
Technical field
The utility model relates to the vacuum blood drawing technique field, particularly relates to a kind of two-way serum separator tube.
Background technology
Existing serum separator tube, after taking a blood sample and separating by hydro-extractor, blood sample and separation gel are divided into serum, separation gel and three layers of haemocyte from top to bottom successively in pipe.In procedure, sometimes need to take serum, and sometimes need to take haemocyte analysis.Serum can directly stretch into sampling probe wherein and extract owing to being in ground floor.But haemocyte is in the bottom of serum separator tube, if arrive again in the haemocyte after adopting sampling probe to pass serum, separation gel, sampling needle will inevitably be brought into the molecule of a small amount of serum and separation gel in the haemocyte, has affected so undoubtedly the accuracy of haemocyte chemical examination.
The utility model content
Solution the deficiencies in the prior art, the two-way serum separator tube that provides a kind of medical personnel of supplying directly to extract selectively haemocyte or serum and not disturbed by other materials are provided the utility model.
The scheme that solves the utility model technical matters is:
Two-way serum separator tube is made of conduit sealing-plug, splash cap, plug, conduit, supervisor and bottom plug.Wherein, supervisor is that the 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.
Be plugged with plug in supervisor's the upper port, there is a vertical through holes at the middle part of plug.Conduit is a straight tube, and the upper end of conduit is in the vertical through holes of described plug, and the outer wall of conduit upper end and the inwall of described vertical through holes are bonding to be an integral body.The lower end of conduit is placed in the upper end of described bottom plug and becomes interference fit to concern with bottom plug.The top of described vertical through holes is plugged with the conduit sealing-plug, and the lower end of conduit sealing-plug is in and becomes the interference fit relation in the upper port of described conduit and with conduit.The degree of depth that described bottom plug inserts in the conduit inserts in the degree of depth among the supervisor greater than described plug.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 pass plug and be inserted into the outer wall of conduit and supervisor's inwall between annular space in.Until blood sampling with after centrifuging finishes, if need to take serum, directly sampling probe is inserted into conduit and be responsible between annular space in can extract serum; If need to 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 broken away from, then the conduit sealing-plug is upwards extracted from the top of plug, this moment, the inside owing to conduit communicated with supervisor's inside, and conduit and supervisor all communicate with atmospheric pressure, therefore haemocyte lower port from conduit under Action of Gravity Field upwards pours in the conduit, at this moment, directly use sampling probe from the vertical through holes of plug, to extend in the conduit and just can be drawn into pure haemocyte.
Adopt such scheme, compared with prior art, the utlity model has following marked improvement:
1. owing to adopting the utility model, both can directly extract serum, can directly extract haemocyte again, compare with existing common separation pipe, have double effects, for sampling work provides convenience.
2. because the utility model can be avoided the interference of serum and separation gel for the lab technician in taking the process of haemocyte, directly sampling probe is inserted in the haemocyte, the haemocyte that obtains like this has higher purity, has greatly improved the accuracy of haemocyte chemical examination.
3. production of the present utility model can utilize existing general blood collection tube to transform, and need not a complete set and again produces.So just utilize existing resource, saved production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
When Fig. 2 directly extracts haemocyte for the employing sampling probe, structural representation of the present utility model.
Among the figure: 1. conduit sealing-plug 2. splash cap 3. plugs 4. conduits 5. are responsible for 6. bottom plugs, 7. serum, 8. separation gels, 9. haemocytes
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Two-way serum separator tube is made of conduit sealing-plug 1, splash cap 2, plug 3, conduit 4, supervisor 5 and bottom plug 6.Wherein, supervisor 5 is that the 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.
Be plugged with plug 3 in supervisor 5 the upper port, there is a vertical through holes at the middle part of plug 3.Conduit 4 is straight tubes, and the upper end of conduit 4 is in the vertical through holes of described plug 3, and the outer wall of conduit 4 upper ends and the inwall of described vertical through holes are bonding to be an integral body.The lower end of conduit 4 is placed in the upper end of described bottom plug 6 and concerns with 6 one-tenth interference fit of bottom plug.The top of described vertical through holes is plugged with conduit sealing-plug 1, and the lower end of conduit sealing-plug 1 is in the upper port of described conduit 4 and with 4 one-tenths interference fit of conduit and concerns.The degree of depth that described bottom plug 6 inserts in the conduit 4 inserts in the degree of depth of being responsible in 5 greater than described plug 3.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 pass plug 3 and be inserted into the outer wall of conduit 4 and be responsible in the annular space between 5 the inwall.Until blood sampling with after centrifuging finishes, if need to take serum 7, directly sampling probe is inserted into conduit 4 and is responsible in the annular space between 5 and can extracts serum; If need to take haemocyte, first with 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 broken away from, then conduit sealing-plug 1 is upwards extracted from the top of plug 3, this moment, the inside owing to conduit 4 communicated with supervisor 5 inside, and conduit 4 and supervisor 5 all communicate with atmospheric pressure, therefore haemocyte 9 lower port from conduit 4 under Action of Gravity Field upwards pours in the conduit 4, at this moment, directly use sampling probe from the vertical through holes of plug 3, to extend in the conduit 4 and just can be drawn into pure haemocyte 9.
