Abstract
The utility model relates to the technical field of vacuum blood collection, in particular to a longitudinal breakaway type test tube lining. The longitudinal breakaway type test tube lining is composed of a push-pull rod, a cover edge, an avoidance cover, a tapered head and a clamping edge. The avoidance cover is formed by combining an upper cylindrical body and a lower cylindrical body, the two cylindrical bodies have different outer diameters, a longitudinal section of each cylindrical body is in the shape of an inverted T, the tapered head is made of polytetrafluoroethylene and is a big-end-up cone, the push-pull rod is in the middle of the upper plane of the tapered head and is cylindrical, the push-pull rod and the tapered head are combined into a whole, the cylindrical clamping edge is located at the edge of the upper plane of the tapered head and forms a whole with the tapered head, and an upper opening of the clamping edge is arranged at the lower end of the avoidance cover in a sleeved mode. Due to the longitudinal breakaway type test tube lining, a sampling needle is enabled not to contact an impurity layer floating on the surface of blood serum at all in the processes of stretching into and separating from a rubber tube, and therefore accuracy of test results of blood samples is improved.
Description
Technical field
The utility model relates to the vacuum blood drawing technique field, particularly relates to a kind of vertical disengaged test tube liner.
Background technology
It is drawn blood, after the centrifugal treating, has one deck impurity and float on the serum surface to existing separation sebific duct.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 often can be blocked in a single day from the floating layer of impurity process; stop up even cause half of sampling probe, also can cause the blood preparation testing result inaccurate.This part impurity mainly is comprised of the materials such as little molecule micelle in the fiber protein yarn in the blood, grease and the separation gel.Because chemical property and the physical property of described impurity have diversity, with its fast, intactly to remove be very difficult.
The utility model content
The utility model is for solving the deficiencies in the prior art, provide a kind of and need not to remove the impurity on serum surface for the medical personnel, just can avoid sampling probe in extracting the serum process, contact with impurity fully, the serum purity that assurance is extracted, avoid the blocked vertical disengaged test tube liner of syringe needle.
The scheme that solves the utility model technical problem is: vertical disengaged test tube liner, and by pull bar, cover rim, dodge lid, conical head and card along consisting of.
Wherein, dodging lid and be the longitudinal cross-section that is combined into by two different cylinders of overall diameter up and down is the cylinder of inverted "convex" shape, the first half of dodging lid is the larger cylinder of overall diameter, the Lower Half of dodging lid is the less cylinder of overall diameter, 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 of the annular that lid is combined as a whole, and the overall diameter of cover rim is greater than the overall diameter of heparin tube.Dodge the overall diameter of the first half of lid 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 on the upper plane of conical head is to be holistic columniform pull bar with conical head, to be holistic columnar card edge with conical head at the edge on the upper plane of conical head, card the suitable for reading of edge is placed on the lower end of dodging lid, and becomes the interference fit relation with the lower end of dodging lid.
During operation, the lab technician pulls up splash cap and the plug of blood sampling spout first, again the utility model is inserted the suitable for reading of heparin tube from top to bottom, and the top edge of guaranteeing the card edge is lower than the impurity layer that floats on the serum surface, then pinch upper end and downward the exerting oneself of pull bar, make card along mutually breaking away from the end opening of dodging lid, at this moment, serum below impurity layer can and be dodged slit between the lower end of lid from the top edge on card edge and be flow into and dodge the lid, just can be drawn into pure pure serum in the lid from dodging with common syringe at last.
Adopt such scheme, compared with prior art, the utlity model has following marked improvement:
1. because the utility model can make sampling probe in stretching into the process of separating sebific duct, do not come in contact with the impurity layer that floats on the serum surface fully, this situation of just effectively having avoided existing sampling probe to be stopped up by impurity in extracting the serum process occurs, and has also improved the accuracy of blood preparation testing result simultaneously.
2. the utility model is simple in structure, with low cost, can be common to existing all vacuum test tubes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. pull bar 2. cover rims 3. are dodged and are covered 4. conical heads, 5. cards along 6. serum, 7. separation gels, 8. haemocytes, 9. impurity layers, 10. heparin tubes
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Vertical disengaged test tube liner, by pull bar 1, cover rim 2, dodge cover 3, conical head 4 and blocking consists of along 5.
Wherein, dodge that to cover 3 be that the longitudinal cross-section that is combined into by two different cylinders of overall diameter up and down is the cylinder of inverted "convex" shape, dodge that to cover 3 the first half be the larger cylinder of overall diameter, dodge that to cover 3 Lower Half be the less cylinder of overall diameter, 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.Dodge the overall diameter that covers 3 the first half 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 on the upper plane of conical head 4 is to be holistic columniform pull bar 1 with conical head 4, at the edge on the upper plane of conical head 4 be with conical head 4 for holistic columnar card along 5, card along 5 suitable for reading be placed in to dodge cover on 3 the lower end, and cover 3 lower end and become the interference fit relation with dodging.
During operation, the lab technician pulls up splash cap and the plug of blood sampling spout first, again the utility model is inserted 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 upper end and downward the exerting oneself of pull bar 1, make card cover 3 end opening and mutually break away from dodging along 5, at this moment, serum 6 below impurity layer 9 can cover slit between 3 the lower end from the top edge and dodge of card along 5 and flow into to dodge and cover 3, just can be drawn into pure pure serum in 3 from dodging to cover with common syringe at last.
