The utility model is composed of a casing, a partition board, a separation chamber and a test tube chamber which are formed by the end covers. A blood serum plasma separating device is arranged in the separation chamber, a graded tube is fixed in the test tube chamber, the bottom of the separation chamber is provided with a blood intake pipe, the blood intake pipe is provided with a blood taking needle base, and the blood taking needle base is provided with a blood taking needle. When the utility model is used for blood sampling, the blood sampling section can be fixed by a blood sampling person, the vascular wall penetration which brings pains to babies can be eliminated, the bacterial contamination is eliminated, the hemolysis is avoided, the blood sampling quality is ensured, and the test result is more accurate and reliable.
Description
This utility model belongs to the blood sampling device technical field.
In the medical test project, check body circulation blood specimen occupies an important position.In order to guarantee quality inspection and increasing work efficiency, easy, promptly collect qualified blood preparation, and accurately isolate serum and blood plasma apace, be important link.For many years, people continue to use traditional syringe collecting blood sample always, and for preventing to intersect disease propagation, what have uses disposable syringe instead.Adopt two kinds of above-mentioned syringe collecting blood samples, its major defect is:
1, the fixing blood sampling site of blood sampling person.During blood sampling, blood sampling person wants stable injectable device on the other hand, the outside pull pintle of another hands, blood could be extracted out in human body, when gathering the infant blood preparation, because of infant is subjected to touching behind the pain stimulation, can not cooperate with blood sampling person, and blood sampling person can not fix its blood sampling site with hands, therefore blood sampling difficulty, and the phenomenon that the blood sampling failure often being arranged or wear out blood vessel wall takes place, cause suffering to infant, for avoiding the generation of this type of phenomenon, often need the head of a family to assist, fixedly blood sampling site.
2, quality of blood drawn can not get guaranteeing.With the blood preparation that syringe collects, all must once more it be entered in the test tube and just can check, in this course, hemocyte is owing to be squeezed and repeatedly touch matsurface, breaks easily and haemolysis occurs, has a strong impact on quality inspection.
The purpose of this utility model is a fixedly blood sampling site and guarantee the hemostix of quality of blood drawn of a kind of person of blood sampling of design.
This hemostix comprises open shell, in by the cavity that shell surrounded, be provided with the dividing plate that is fixed on the shell bottom surface, dividing plate is divided into separation chamber and test tube chamber with this cavity, in the separation chamber, be provided with the serum plasma separating unit, at the indoor graded tube that is fixed with of test tube, the separation chamber, the opening end of test tube chamber is connected end cap, part in the end cap seal separation chamber is provided with protruding medicated cap, the blood vessel that advances that communicates with the separation chamber is housed on the bottom surface of separation chamber, the outer end of advancing blood vessel is sat at the bottom of being plugged with rubber seal plug and being socketed with blood taking needle, be fitted with on the bottom surface of sitting at the bottom of the blood taking needle and can penetrate rubber seal plug and advance the blood taking needle that blood vessel communicates, adopt that the outside of seat is set with the Bacteria-prevention cap that holds blood taking needle at the bottom of the celestial pin; The separation block that the serum plasma separating unit is included in that transverse sealing between shell and the dividing plate is placed and can slides along dividing plate and outer casing inner wall, on the end face that advances blood vessel, be provided with cone tank at separation block, sealing is plugged with conical plug on the cone tank, conical plug also has spring to be connected with separation block, on the groove bottom of cone tank, be connected to separator tube, the other end of separator tube is connected with the capillary sebific duct, the other end of capillary sebific duct is penetrated into by the hole, garden on the dividing plate that test tube is indoor to be connected with graded tube, and the capillary sebific duct will be connected with hole, the garden sealing on the dividing plate; Separation chamber, capillary sebific duct and graded tube are vacuum state.
During use, pull out Bacteria-prevention cap, hand-held this hemostix, blood taking needle is thrust subcutaneous, and rapidly the other end of blood taking needle is penetrated rubber seal plug and advance blood vessel and be communicated with, then blood taking needle is thrust in the blood vessel, the more fixing blood sampling site of proficiency, because the separation chamber is a vacuum state, in the double-deck effect of the negative pressure of the blood pressure (malleation) of human body and separation chamber down, blood of human body flow into rapidly in the separation chamber, so uses this hemostix, blood sampling is convenient, can not wear out blood vessel wall and cause suffering to infant.
Blood sampling finishes, and cuts the protruding medicated cap on the end cap, and this hemostix is placed on the separator, connects the separator power supply, and separator work drives the rotation of this hemostix.When separator has just been started working, rotating speed is low, and to the pulling force of conical plug and the blood buoyancy to conical plug, conical plug still seals and is plugged in the cone tank centrifugal force less than spring, serum or separating plasma are come out in the slowly heavy bottom that collects the separation chamber of blood cell in the blood at this moment; When rotating speed raises, after centrifugal force increases to and overcomes the pulling force and serum or the buoyancy of blood plasma to conical plug of spring to conical plug, conical plug breaks away from cone tank, serum or blood plasma are through separator tube, the capillary sebific duct enters in the graded tube, outflow along with serum or blood plasma, under atmospheric pressure, the serum plasma separating unit also moves down to the bottom, separation chamber along dividing plate and outer casing inner wall thereupon, bottom surface up to conical plug touches blood cell, because the buoyancy that the buoyancy that blood cell produces the conical plug bottom surface obviously produces the conical plug bottom surface greater than serum or blood plasma, under the buoyancy of the pulling force of spring and blood cell, conical plug overcomes action of centrifugal force and is plugged into again in the cone tank, and separator tube is blocked.Isolating serum or blood plasma from taking a blood sample to all is to carry out under air-tight state, has stopped cell contamination, has avoided the generation of haemolysis, has guaranteed quality of blood drawn, thereby has made assay more accurately and reliably.This hemostix is disposable use.
Accompanying drawing shows embodiment of the present utility model, wherein
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of push rod.
