Description
Technical field
The present invention relates to vacuum blood drawing technique field, particularly relate to a kind of impurity avoiding-type and separate sebific duct.
Background technology
Existing separation sebific duct, is drawing blood after centrifugal treating to it, has one deck impurity and floats on serum surface.Because impurity floats on serum surface; draw in the process of serum from the mouth of pipe extend into serum downwards at sampling probe, 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 is mainly made up of materials such as the little molecule micelles in the fiber protein yarn in blood, grease and separation gel.Because chemical property and the physical property of described impurity have diversity, by its fast, intactly 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 extracting in serum process completely, the serum purity that ensures to extract, avoid the blocked impurity avoiding-type separation sebific duct of syringe needle.
The scheme that solves the technology of the present invention problem is: impurity avoiding-type separates sebific duct, by SS, splash cap, plug, sinking space, dodge head and test tube forms.Splash cap is the cylindrical plastic housing that lower end opens wide, there is a SS upper end.The outline of plug is cylindrical, the sinking space that the upper surface of plug has is one columniform, upper end opens wide, the lower end of plug is the columnar head of dodging being combined as a whole with plug, dodge cylindrical space in head and communicate with the sinking space of its top, the outline of dodging the lower end closed of head and dodging a lower end is up big and down small circular cone.Described circular cone and plug and sinking space are coaxial.Vertical distance between the summit of described circular cone and the bottom surface of plug is 0.6-2.0cm, and plug is butyl rubber with the material of the combination of dodging head, adopts teflon to carry out overlay film processing at the outside surface of the circular cone of dodging a lower end.In the first half of plug in splash cap, and become interference fit relation with the inwall of splash cap, the lower end plug of plug becomes interference fit relation in the upper end of test tube and with the inwall suitable for reading of test tube, and the inwall of the Lower Half of the splash cap outer wall suitable for reading with test tube becomes clearance fit relationship.
In when blood sampling, first to guarantee that at the mouth of pipe that separates sebific duct the liquid level of pipe inner blood sample is higher than the circular cone of dodging a lower end straight up time.The separation sebific duct that blood sample is housed is carried out in the process of centrifugal treating, haemocyte in separation gel and blood sample, serum, according to proportion separately, under the effect of centrifugal force, in separation sebific duct, move to the position of each self-stabilization, and impurity in pipe is because proportion is the lightest, just move to plug direction, in the time dodging the circular cone of cephalic par described in impurity touches, because the side of circular cone is inclined-plane, its surface has adopted again teflon to carry out overlay film processing simultaneously, there is the less coefficient of sliding friction, therefore impurity slips over conical surface under the guiding on circular cone inclined-plane, continue the bottom motion to plug, and can not be stranded on circular cone inclined-plane, until it moves to serum surface.
In the time that centrifugal treating finishes, dodge the circular cone of lower end of head completely in pure serum, and impurity layer in dodge a lower end circular cone top and form impurity layer.
Now, only sampling probe need be inserted straight down from the SS at splash cap top, and guarantee that sampling probe passes from dodging a summit for lower end circular cone, due to the top of impurity layer in described circular cone, the syringe needle that enters the sampling probe of serum can not come in contact with impurity layer completely.The sampling probe that said process adopts is State Intellectual Property Office's disclosed application number was 201020665773.9 on July 20th, 2011 " a kind of sampling probe of analyser ".
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
Because can making sampling probe, the present invention separates in the process of sebific duct stretching into, 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 extraction serum process occurs, and has also improved the accuracy of blood preparation testing result simultaneously.
