Abstract
The utility model discloses a disposable aseptic venous blood sampler utilizing the theory of negative-pressure extraction. A needle body and a test tube are combined into integration by a test tube sleeve which is provided with screw threads. The utility model has the advantages of convenient operation, high safety, simple manufacture technology, and good popularity.
Description
This utility model belongs to the venous blood collection instrument of a kind of medical domain blood testing special use.
At present, public disposable plastic injector has replaced the syringe of traditional glass, no longer reclaims.But blood re-injects test tube after still being extracted by syringe, owing to twice take out, annotate and make operation still loaded down with trivial details.
The purpose of this utility model is the principle according to negative pressure-pumping, and a kind of tool and aseptic vein hemostix of the incorporated disposable use of test tube of will taking a blood sample is provided.
The purpose of this utility model is achieved in that it is made up of catheter needle, needle cap, test tube cover, test tube nipple cap, test tube five parts.Catheter needle and plastic catheter pin are embedded in the plastic handgrip in pin stalk rear end, and the needle handle rear end connects 60mm flexible plastic conduit, and the conduit other end is included in the plastics pintle, and pintle has uropore portion bonnet.Catheter needle muzzle needle cap, the test tube cover is made by rigid plastics, and front end has a pars papillaris, and the head diameter of pars papillaris equates with the aperture of pintle metapore, and is tapered slightly, so that envelope is close when connecting.Test tube is with female thread, the rear end with test tube weigh mutually and connect, the nipple of test tube nipple cap protection test tube cover made of plastic front end.Test tube has scale to be made with thick slightly flexible plastic (transparent), and requiring to possess has better elastic.The test tube upper oral part has the edge and a symmetric thread of compacting, and its diameter conforms to the internal diameter of test tube external threading, when they screw mutually, promptly seals close air tight.
Advantage of the present utility model: easy to operate, once take a blood sample successfully; Processing technology is simple, and injector syringe and test tube two parts are reduced to one, are plastic; Price is low, is 1/2nd of former plastic.
Figure one is the aseptic vein hemostix external view of disposable use.
Figure two is the aseptic vein hemostix STRUCTURE DECOMPOSITION of disposable use figure.
Among the figure, 1, catheter needle, 2, needle cap, 3, the test tube cover, 4, the test tube nipple cap, 5, test tube.
Below in conjunction with drawings and Examples this utility model is described.
Select blood sampling site, routine disinfection skin punctures successfully, fixed needle (1) is got test tube (5), discards test tube nipple cap (4), push test tube (5) relatively with hand thumb, forefinger, middle finger, outside the air discharge pipe, open the uropore bonnet of catheter needle, make its uropore and test tube nipple close proximity, the extruding of slowly abandoning the right hand flows in the test tube (5) blood, and to requirement, blood sampling finishes, with catheter needle (1) by extracting hemostasis by compression in the blood vessel.
Claims (3)
1, the aseptic vein hemostix of disposable use is made up of catheter needle, needle cap, test tube cover, test tube nipple cap, test tube, it is characterized in that: the test tube cover that has female thread is connected as a single entity needle body and test tube.
2, hemostix according to claim 1 is characterized in that: the edge and a symmetric thread of compacting arranged at test tube top, and its diameter conforms to and seals close with threading path in vitro.
3, according to claim 1,2 described hemostixes, it is characterized in that: test tube is made for the soft transparent plastics, is marked with scale.
