Abstract
The utility model discloses a separator tube for blood serum and blood corpuscle, which comprises a transparent tube body and a sealing plug matching with the tube body, wherein diameters of cross sections of the tube body decrease gradually from a tube mouth to a tube bottom, an included angle between a tube body wall and a vertical axes is 1.5-1.8 degrees, and the tube body is provided with a separating agent inside. The utility model can completely separate the blood serum and the blood corpuscle in blood without generating turbidity phenomenon while extracting, the viscosity of the separated blood serum is changeless after long time laying, and the blood serum and the blood corpuscle do not mix when slightly oscillating.
Description
Technical field
The utility model relates to a kind of medical apparatus, relates in particular to a kind of clinical examination process that is used for, the separator tube that the serum in the blood is separated with haemocyte.
Background technology
At present, separation of serum all adopts the identical cuvette of diameter up and down with haemocyte.Separated plasma to be adopted and adds behind the anti-coagulants way of centrifugation again, blood plasma is separated with haemocyte, but it is muddy easily when getting blood plasma, separate not thorough, blood sample long slightly back standing time is haemolysis easily, if when adopting the automatic analyzer analysed for plasma, the easy blocking pipe of unprecipitated haemocyte, blood plasma must take out and can store.Separation of serum adopts after the blood natural coagulation method of centrifugation more more, when taking out serum and analyze, has a muddy easily problem equally.
In addition, Japanese patent application publication No. Sho 51-83654 discloses a kind of blood testing container, has wherein contained thixotroping serum or plasma separation compositions in the blood collection tube bottom, for example, and the mixture of siloxanes and silica.Blood is collected in the blood collection tube, places reasonable time and centrifugal.Then, gluey serum or plasma separation compositions becomes and can flow under centrifugal action.Simultaneously, the proportion of gluey serum or plasma separation compositions is between serum or plasma component (proportion about 1.02) and blood clot or cellular component (proportion about 1.08) (1.03-1.07).Therefore, isolate compositions floats gradually from the bottom of pipe in collecting blood, and is positioned between serum or plasma layer and blood clot or the cellular layer, to determine successfully separating that serum or plasma fraction separate from blood clot or cellular component.At this moment can from blood collection tube, tell at an easy rate from the serum or the plasma fraction of blood or cellular component separation, carry out various detections.Also can not need transfer to other container storage.But such thixotroping serum or plasma separation compositions can contain the main component except that mentioned component.For example, isolate compositions has advised also containing the reagent of oligomer and adjusting proportion, viscosity and/or thixotropic nature except that containing aforementioned siloxanes.The example of oligomer comprises: halogenated hydrocarbon oligomer, acrylate oligomer, ester oligomer and cyclic hydrocarbon oligomer.The example of conditioning agent comprises inorganic particle such as silica and kaolin and organic gel agent such as benzylidene sorbitol.Yet aforementioned organic siliconresin shows compatibility obviously poor and proportion that be made up of inorganic particle and viscosity modifier, and extremely sensitive to being separated at short notice.Curing reaction takes place when equally, organic siliconresin carries out irradiation-sterilize.Therefore, the organic siliconresin there be limited evidence currently of uses.And the halogenated hydrocarbon oligomer when burning disposal, produces hydrogen halide, and it may cause damage or environment is caused harmful effect incinerator.Each contains a lot of polar groups in molecule for aforementioned acrylate oligomer and ester oligomer, and having when detecting blood concentration increases the problem that drug absorption takes place.
The utility model content
The purpose of this utility model is to overcome the problems referred to above of the separator existence that in the prior art serum in the blood is separated with haemocyte, and a kind of serum and haemocyte separator tube are provided.The utility model can thoroughly separate the serum in the blood with haemocyte, and can not produce turbid phenomenon when extracting, and isolated serum is through the long-time viscosity no change of placing, and serum and haemocyte do not mix through slightly waving yet.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of serum and haemocyte separator tube, comprise transparent tube body and the sealing-plug that cooperates with body, it is characterized in that: the diameter of described body cross section is low from the mouth of pipe to pipe to be reduced gradually, and the angle of tube body wall and vertical axis is 1.5 degree, one 1.8 degree, and release agent is housed in the body.
Described sealing-plug is a rubber stopper, and the rubber stopper cross section is " protruding " shape, protruding end and body fitted seal.
Be snapped with splash cap on the described sealing-plug.
Adopt advantage of the present utility model to be:
One, the utility model can thoroughly separate the serum in the blood with haemocyte, and can not produce turbid phenomenon when extracting, the angle that adopts tube body wall and vertical axis is 1.5 degree-1.8 degree, make isolated serum through the long-time viscosity no change of placing, serum and haemocyte do not mix through slightly waving yet.
Two, the utility model has overcome the defective of existing separation of serum or the existence of haemocyte utensil, the efficient and the effect of blood sample analysis are improved greatly, utilize this disposable minute blood test tube, jam-pack rubber stopper behind the branch blood, blood plasma or serum can be stayed in vitro and store, save the storage utensil, simplified the storage means.
Three, the utility model sealing-plug is a rubber stopper, and rubber stopper is " protruding " shape, and protruding end and body fitted seal can be stayed in vitro blood plasma or serum for a long time and stored.
Four, adopt the separator tube of serum of the present utility model and haemocyte, preparation technology is simple, and raw material is easy to get, and cost is low, and environmentally safe.
