Abstract
The utility model discloses a disposable micro-blood sampling device, belonging to the field of medical instruments. The structure comprises a blood sampling needle, a connecting needle, a connecting pipe and a negative pressure hose, wherein, the negative pressure hose forms a sealed negative pressure cavity through the rubber plugs arranged at both ends; the blood sampling needle is connected with the connecting needle through the connecting pipe; the connecting needle can be inserted into the negative pressure cavity through the rubber plug at one end of the negative pressure hose. Compared with the prior art, the disposable micro-blood sampling device of the utility model is characterized in simple structure, convenient use and the capability of ensuring the blood sampling quality, which can be widely applied to various medical blood sampling processes.
Description
Technical field
This utility model relates to the treatment instrument field, especially a kind of disposable micro hemostix that is applicable to the blood testing process.
Background technology
In the prior art, most medical treatment blood sampling still utilizes ordinary syringe that blood is extracted out earlier, and then blood is pushed in the vessel such as test tube temporary.Though syringe and test tube are medical treatment article commonly used, and be cheap and easy to get,, no matter be in the blood drawing process, still blood is being pushed in the process of test tube, all entrained air has very easily had a strong impact on quality inspection.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of disposable micro hemostix at above-mentioned deficiency of the prior art, and that this hemostix has is simple in structure, easy to use, can guarantee characteristics such as quality of blood drawn.
The technical scheme that its technical problem that solves this utility model adopts is: the disposable micro hemostix, this hemostix comprises blood collection needles, connects syringe needle, connecting leg and negative pressure flexible pipe, the negative pressure flexible pipe forms the sealing negative pressure cavity by the rubber closure that is arranged on its two ends, blood collection needles be connected syringe needle and be connected by connecting leg, connecting syringe needle can insert negative pressure cavity by the rubber closure of negative pressure flexible pipe one end.
In order to prevent air admission in the blood collection procedure, clip can be set on connecting leg.
Scribble the anticoagulant layer at the negative pressure hose inner wall.
Be marked with scale at the negative pressure flexible pipe.
During use, utilize the blood pressure of health and the pressure reduction between the negative pressure cavity, make blood flow into the negative pressure flexible pipe voluntarily; Then, pull out the connection syringe needle, can give negative pressure flexible pipe numbering to be checked.During detection, take out the rubber closure of the negative pressure flexible pipe other end, can begin to detect.
Disposable micro hemostix of the present utility model is compared with prior art, has following outstanding beneficial effect:
(1) the temporary process that will draw blood process and push test tube is finished synchronously, has overcome in the operating process of prior art easily entrained air fully, influences the deficiency of analytical quality.
(2) simple in structure, cost is low, characteristics such as easy to use.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model disposable micro hemostix.
The specific embodiment
Explain below with reference to Figure of description disposable micro hemostix of the present utility model being done.
Disposable micro hemostix of the present utility model is made of blood collection needles 1, connection syringe needle 2, connecting leg 3, negative pressure flexible pipe 4, rubber closure 5 and clip 7.
Two rubber closures 5 are separately positioned on the two ends of negative pressure flexible pipe 4, make it to form sealing negative pressure cavity 6.Negative pressure flexible pipe 4 inwalls scribble the anticoagulant layer, and outer wall indicates scale.Standby behind the evacuation.
Blood collection needles 1 be connected syringe needle 2 and be connected by connecting leg 3.Clip 7 is arranged on the connecting leg 3.
Connect syringe needle 2 and can insert negative pressure cavity 6 by the rubber closure 5 of negative pressure flexible pipe 4 one ends.
During blood drawing, at first to the skin disinfection, blood sampling is earlier then treated will connect syringe needle 2 insertion negative pressure flexible pipes 4 again after blood flows into blood collection needles 1.At this moment, unclamp clip 7, blood just can utilize inside and outside differential pressure from flowing into negative pressure flexible pipe 4.When treating that blood reaches the requirement blood sampling volume, extract connection syringe needle 2, give negative pressure flexible pipe 4 numberings to be checked getting final product.
During check, take out the rubber closure 5 of negative pressure flexible pipe 4 other ends, the suction needle insertion mensuration with testing instruments gets final product then.
Its processing and fabricating of disposable micro hemostix of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
Claims (4)
1, disposable micro hemostix, it is characterized in that this hemostix comprises blood collection needles, connects syringe needle, connecting leg and negative pressure flexible pipe, the negative pressure flexible pipe forms the sealing negative pressure cavity by the rubber closure that is arranged on its two ends, blood collection needles be connected syringe needle and be connected by connecting leg, connecting syringe needle can insert negative pressure cavity by the rubber closure of negative pressure flexible pipe one end.
