Technical field
This utility model relates to a kind of blood-taking device, and particularly the quantitative vacuum blood sampler of a kind of clinical laboratory, belongs to medical instruments field.
Background technology
Blood test is one of conventional medical test project, at present, when gathering blood clinically, usually adopts disposable syringe to draw blood, then injects in test tubes by blood, after deliver to clinical laboratory and chemically examine.But this Blood collection exists more drawback, such as, 1, take a blood sample time need to carry out blood transfer, not only step is more, adds burden to doctor, and easily causes blood contamination; 2, this Blood collection make blood in atmosphere residence time long, easily make blood go bad, make testing data inaccurate; 3, when needs quantitatively extract blood test time, to need by other instruments, but can blood contamination be caused again by during other instruments.Given this, be necessary to design a kind of novel clinical laboratory's blood-taking device, solve current Problems existing with this.
Summary of the invention
The purpose of this utility model is the drawback in order to solve present stage blood-taking device, and the quantitative vacuum blood sampler of a kind of clinical laboratory proposed.
To achieve these goals, this utility model have employed following technical scheme: the quantitative vacuum blood sampler of a kind of clinical laboratory, comprise blood collection needles, flexible pipe, test tube and vacuum withdraw device, one end of described blood collection needles connecting hose, the other end of described flexible pipe passes in vitro, the opening of described test tube is provided with sealing-plug, described sealing-plug is provided with nut, describedly in vitro be provided with piston, the middle part of described piston is connected with one end of screw rod, the other end of described screw rod passes sealing-plug and the nut that is threaded, described one end in vitro also passing into exhaustor, the other end of described exhaustor connects vacuum withdraw device.
As a kind of optimal technical scheme of the present utility model, described blood collection needles is provided with needle handle.
As a kind of optimal technical scheme of the present utility model, described blood collection needles and hose connection place are provided with check valve.
As a kind of optimal technical scheme of the present utility model, described test tube is provided with graduation mark.
As a kind of optimal technical scheme of the present utility model, described vacuum withdraw device is vacuum pump.
As a kind of optimal technical scheme of the present utility model, described nut is ingot shape.
