Abstract
The utility model of disposable blood collector with sub-atmospheric pressure style and with vacuum inside relates to a blood collector composed of two ends and a detecting test tube. An adjusting valve body with an adjusting knob on the central through-hole slides and is installed into the open end. The other end is an enclosed glass blood-containing tube of semi-circle shape. By butt-to-butt joint between an orifice of an external aspirator of a vacuum pump and an interface end of a blood taking needle of the blood collector. The air inside the tube is evacuated, and the inside of the tube is formed into vacuum to generate sub-atmospheric pressure.
Description
Technical field
This utility model belongs to the medical inspection apparatus, realizes blood sampling, contains that blood is disposable to be finished.
Background technology
Existing blood taking instrument mostly is and uses earlier blood collection needle, and the method for check test tube is injected in the back.This method probably causes the generation and the secondary cross infection of haemolysis.
Summary of the invention
This utility model purpose: be to provide a kind of blood sampling, contain the disposable apparatus of blood.
The technical scheme that this utility model adopted: be that the adjusting knob regulation valve body is slided the threading opening, the other end is Sheng blood vessel, the check test tube formation hemostix of semi-circular closed glass with having on the central through hole.
Dock with the blood collection needles interface end on the hemostix by the external mouth of pipe of bleeding of vacuum pump, unscrew the control valve knob and open valve, gas is found time in will managing; After reaching setting pressure in the pipe, screw control valve knob valve-off, just form vacuum in the pipe and produce negative pressure.
Advantage of the present utility model:
1, simple in structure, easy operating, simple and efficient;
2, with low cost, the garbage secondary pollution is little;
3, owing to be disposable use, just effectively prevent haemolysis and secondary cross infection;
4, the safety in blood sample seal storage and the transportation is taked in assurance, improves the accuracy rate of assay.
Description of drawings
This figure is this utility model structure chart, and among the figure: 1-contains blood vessel, check test tube; 2-control valve knob; The 3-regulation valve body.
The specific embodiment
In conjunction with illustrating, the sliding threading of the 3-regulation valve body opening of 2-adjusting knob, 1-Sheng blood vessel, the check test tube formation hemostix that the other end is semi-circular closed glass will be had on the central through hole.Dock with the blood collection needles interface end by the external mouth of pipe of bleeding of vacuum pump, unscrew 2-control valve knob and open valve, gas is found time in will managing; After reaching setting pressure in the pipe, screw 2-control valve knob valve-off, just form vacuum like this in the pipe and produce negative pressure.
In blood collection procedure, blood collection needles on hemostix is thrust by after in the blood sampling subject, unscrews 2-control valve knob and opens valve, is in negative pressure state because 1-contains in the blood vessel, makes blood reflux automatically.After satisfying the blood sampling measuring requirement, screw 2-control valve knob valve-off, withdraw from by syringe needle in the blood sampling subject, just finish blood collection procedure, realize containing the blood function and take the blood sample seal storage.
Claims (1)
- Vacuum negative pressure type disposable blood taking device in this utility model is characterized in that: will have the regulation valve body (3) of adjusting knob (2) on the central through hole. sliding threading opening, the other end are that Sheng blood vessel (1), the check test tube of semi-circular closed glass constitutes hemostix.
