Abstract
The utility model discloses a blood-taking needle for medical examination, which comprises a syringe. The end of the syringe is provided with a needle; the inside of the syringe is provided with a piston. The blood-taking needle for medical examination is characterized in that: a flow control device is arranged between the needle and the syringe. Due to the adoption of the flow control device which is directly arranged between the syringe and the needle, the flow is controlled and the blood can not be exposed to the air, and the blood quality and the examination accuracy are improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the blood taking needle of blood sampling usefulness when specifically relating to a kind of the check.
Background technology
In medical test, normally the blood of gathering is tested, to get corresponding results.General blood collection procedure is at present: take a blood sample from human body with blood taking needle, in the test tube of then it being packed into.Because the blood of gathering often is exposed in the air, blood is prone to rotten, the result of influence check, so, in blood collection procedure, the blood of being gathered is not exposed in the air, be one of important means that improves assay.
The utility model content
Problem to be solved in the utility model provides a kind of quality of blood drawn height, medical check blood taking needle that test effect is good.
For addressing the above problem, the technical scheme that this utility model adopted is:
Medical check blood taking needle comprises syringe, and the end of syringe is provided with syringe needle, is provided with piston in the syringe, it is characterized in that: be provided with flow control apparatus between described syringe needle and the syringe.
As a kind of improvement:
Described flow control apparatus comprises and syringe needle and the forward check valve that is connected, is provided with reverse check valve between forward check valve and the syringe.
Described reverse check valve is perpendicular to syringe place axis.
As further improvement:
Described reverse check valve is communicated with test tube by pipeline, and test tube is provided with stopper.
This utility model not only can be controlled the flow direction by at syringe and syringe needle flow control apparatus being set directly, but also blood is not exposed in the air, has improved the quality of blood, and then has improved the accuracy of check.
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment.
Among the figure: the 1-syringe; The 2-syringe needle; The 3-piston; 4-forward check valve; The reverse check valve of 5-; The 6-test tube; The 7-stopper.
The specific embodiment
Embodiment: as shown in the figure, medical check blood taking needle comprises syringe 1, and the end of syringe 1 is provided with syringe needle 2, is provided with piston 3 in the syringe 1, is provided with flow control apparatus between described syringe needle 2 and the syringe 1.
Flow control apparatus comprises and syringe needle 2 and the forward check valve 4 that is connected, is provided with reverse check valve 5 between forward check valve 44 and the syringe 1.
Operation principle: syringe needle 2 penetrated in the blood vessel draw blood, at this moment, forward check valve 4 is opened, reverse check valve 5 is in closed condition, after blood drawing is finished, utilizes piston 3 that syringe 2 inner bloods are released, at this moment, reverse check valve 5 is opened, and forward check valve 4 is closed, and blood enters in the test tube 6 by pipeline.
