Abstract
The utility model relates to a disposable blood sampling device for chemical examination and belongs to the field of medical devices. The disposable blood sampling device is provided with a test tube and is characterized in that scale marks are formed on the test tube, a plug is arranged at the top of the test tube, an exhaust pipe and a drainage pipe are arranged on the plug, one end of the exhaust pipe extends into the test tube, an exhaust sac is arranged at the other end of the exhaust pipe, one end of the drainage pipe extends into the test tube, a flexible guide pipe is connected with the other end of the drainage pipe, and a needle is arranged at the tail end of the flexible guide pipe. The disposable blood sampling device can complete the blood sampling operation in one step without needing any interlink, which can not only prevent the contamination of a blood sample but also increase the work efficiency.
Description
Technical field
This utility model relates to medical instruments field, at length says it is a kind of disposable chemical examination blood-taking device.
Background technology
As everyone knows, the blood sampling chemical examination is the important method of patient diagnosed's disease, and existing blood-taking device generally is to use blood collection needle; The interior cover that is about to syringe is pushed into the top; Air in the emptying injection tube thrusts patient's vein with syringe needle then, overlaps in the pull backward again; Blood gets in the injection tube under suction function, again the blood in the injection tube is expelled to chemical examination and in vitro chemically examines.This method is a shortcoming: the one, intermediate link is arranged, and need may pollute blood sample transferring to again in vitro after the blood extraction, the 2nd, blood is expelled to again in vitro also needs the regular hour, is unfavorable for increasing work efficiency.
Summary of the invention
In order to overcome the deficiency of prior art, this utility model provides a kind of disposable chemical examination blood-taking device, can disposable completion blood sampling work, and no intermediate link both can avoid blood sample to pollute, and can increase work efficiency again.
This utility model solves the technical scheme that its technical problem adopted: a kind of disposable chemical examination blood-taking device, be provided with test tube, and it is characterized in that; Test tube is provided with scale, and the top of test tube is provided with stopper, and stopper is provided with exhaustor and drainage tube; Exhaustor one end stretches into test tube, and the other end of exhaustor is provided with Exhaust airbag, and drainage tube one end stretches into test tube; The other end of drainage tube connects flexible catheter, and the end of flexible catheter is provided with syringe needle.
The beneficial effect of this utility model is, can disposable completion blood sampling work, and no intermediate link both can avoid blood sample to pollute, and can increase work efficiency again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the structural representation of this utility model.
1. test tubes among the figure, 2. drainage tube, 3. flexible catheter, 4. syringe needle, 5. exhaustor, 6. Exhaust airbag, 7. stopper, 8. scale.
The specific embodiment
In Fig. 1, this utility model is provided with test tube 1, and test tube 1 is provided with scale 8; The top of test tube 1 is provided with stopper 7, and stopper 7 is provided with exhaustor 5 and drainage tube 2, and exhaustor 5 one ends stretch into test tube 1; The other end of exhaustor 5 is provided with Exhaust airbag 6; Drainage tube 2 one ends stretch into test tube 1, and the other end of drainage tube 2 connects flexible catheter 3, and the end of flexible catheter 3 is provided with syringe needle 4.
This utility model in use, with flexible catheter 3 bending blocking-up circulations of air, after pushing Exhaust airbag 6 then the air in the test tube 1 being discharged; Again syringe needle 4 is thrust patient's vein; And flexible catheter 3 trailed, blood flows in the test tubes 1 through flexible catheter 3, drainage tube 2 under action of negative pressure, observes scale 8; Can take off syringe needle 4 when reaching the blood sampling volume that needs, so just once accomplish blood sampling work.
