Abstract
The invention relates to the technical field of vacuum blood collection, in particular to an avoiding type test tube lining of a fiber protein layer which is formed by a push pull rod, a cover edge, an avoiding cover, a conical head and a clamping edge. The avoiding cover is a cylinder formed by combining an upper cylinder and a lower cylinder with different diameters, and the vertical section of the cylinder is T-shaped. The conical head is a cylinder made of Teflon and is provided with a large top and a small bottom. The middle of an upper plane of the conical head is provided with a cylindrical push-pull rod integrated with the conical head, the cylindrical clamping edge integrated with the conical head is arranged on the edge of the upper plane of the conical head, and an upper opening of the clamping edge is sleeved on the lower end of the avoiding cover. The lining enables a sampling needle not to be contacted with an impurity layer floating on the surface of serum completely in the process that the sampling needle stretches into a separation rubber pipe and improves accuracy of detection results of blood specimens.
Description
Technical field
The present invention relates to vacuum blood drawing technique field, particularly relate to a kind of fibrin layer avoiding-type test tube liner.
Background technology
To existing separated sebific duct, it is drawn blood, after centrifugal treating, has one deck impurity and float on serum surface.Because impurity floats on serum surface; at sampling probe, from the mouth of pipe extend into serum downwards, draw in the process of serum, once syringe needle from the floating layer of impurity process, often can be blocked; even if cause that half of sampling probe stops up, and also can cause blood preparation testing result inaccurate.This part impurity mainly materials such as little molecule micelle in the fiber protein yarn in blood, grease and separation gel forms.Because chemical property and the physical property of described impurity has diversity, by its fast, intactly to remove be very difficult.
Summary of the invention
The present invention is for solving the deficiencies in the prior art, provide a kind of medical personnel of supplying without the impurity of removing serum surface, just can avoid sampling probe contact with impurity in extracting serum process completely, the serum purity that assurance is extracted, avoid the blocked fibrin layer avoiding-type test tube liner of syringe needle.
The scheme that solves the technology of the present invention problem is: fibrin layer avoiding-type test tube liner, and by pull bar, cover rim, dodge lid, conical head and card along forming.
Wherein, dodging lid is the cylinder that the longitudinal cross-section that is combined into by upper and lower two different cylinders of overall diameter is inverted "convex" shape, the first half of dodging lid is the cylinder that overall diameter is larger, the Lower Half of dodging lid is the cylinder that overall diameter is less, dodging the upper and lower side of lid all opens wide, the upper end-face edge of dodging lid has and dodges the cover rim that covers the annular being combined as a whole, and the overall diameter of cover rim is greater than the overall diameter of heparin tube.The overall diameter of dodging the first half of lid is less than the interior diameter of heparin tube.
Conical head is that material is polytetrafluoroethylene (PTFE), up big and down small cone, the middle part of the upper plane of conical head is to be holistic columniform pull bar with conical head, edge in the upper plane of conical head is to be holistic columnar card edge with conical head, card the suitable for reading of edge is placed on the lower end of dodging lid, and becomes interference fit relation with the lower end of dodging lid.
During operation, lab technician first pulls up the splash cap of blood sampling spout and plug, again the present invention is inserted to the suitable for reading of heparin tube from top to bottom, and the top edge of guaranteeing card edge is lower than the impurity layer that floats on serum surface, then pinch the upper end of pull bar and exert oneself downwards, make card along mutually departing from the end opening of dodging lid, now, serum below impurity layer can and be dodged gap between the lower end of lid from the top edge on card edge and be flow into and dodge lid, finally with common syringe, just can in lid, be drawn into pure pure serum from dodging.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the present invention can make sampling probe in stretching into the process of separated sebific duct, do not come in contact with the impurity layer that floats on serum surface completely, this situation of just effectively having avoided existing sampling probe to be stopped up by impurity in extracting serum process occurs, and has also improved the accuracy of blood preparation testing result simultaneously.
2. the present invention is simple in structure, with low cost, can be common to existing all vacuum test tubes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. pull bar 2. cover rims 3. are dodged and covered 4. conical head 5. cards along 6. serum 7. separation gel 8. haemocyte 9. impurity layer 10. heparin tubes
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Fibrin layer avoiding-type test tube liner, by pull bar 1, cover rim 2, dodge cover 3, conical head 4 and card form along 5.
Wherein, dodge that to cover 3 are cylinders that the longitudinal cross-section that is combined into by upper and lower two different cylinders of overall diameter is inverted "convex" shape, dodge that to cover 3 the first half be the cylinder that overall diameter is larger, dodge that to cover 3 Lower Half be the cylinder that overall diameter is less, dodge and cover 3 upper and lower side and all open wide, dodge and cover 3 upper end-face edge and have and dodge the cover rim 2 that covers 3 annulars that are combined as a whole, the overall diameter of cover rim 2 is greater than the overall diameter of heparin tube 10.The overall diameter of dodging the first half that covers 3 is less than the interior diameter of heparin tube 10.
Conical head 4 is that material is polytetrafluoroethylene (PTFE), up big and down small cone, the middle part of the upper plane of conical head 4 is to be holistic columniform pull bar 1 with conical head 4, at the edge of the upper plane of conical head 4, be for holistic columnar card is along 5 with conical head 4, card is dodged on the lower end of covering 3 along 5 suitable for reading being placed on, and covers 3 lower end and become interference fit relation with dodging.
During operation, lab technician first pulls up the splash cap of blood sampling spout and plug, again the present invention is inserted to the suitable for reading of heparin tube 10 from top to bottom, and guarantee that the top edge of card along 5 is lower than the impurity layer 9 that floats on serum 6 surfaces, then pinch the upper end of pull bar 1 and exert oneself downwards, make card cover 3 end opening and mutually depart from dodging along 5, now, serum below impurity layer 96 can be from card along 5 top edge and dodge gap between the lower end of covering 3 flow into and dodge and cover 3, finally with common syringe, just can in 3, be drawn into pure pure serum from dodging to cover.
