Abstract
The present invention relates to a disposable arteriopuncture and venipuncture needle, including a puncture hollow steel needle, its tail portion is connected with a needle seat whose interior is equipped with a one-way valve, and the rear portion of the puncture hollow steal needle is covered with a negative-pressure self-sucking ball bag, and one side hole correspondent to the negative-pressure self-sucking ball bag is opened on the puncture hollow steel needle, so that it overcomes the phenomena which can be produced by adopting existent technology when it is used for making arteriopuncture, the blood ejection can be produced or when it is used for making venipuncture, because it has no negative pressure, and it has no returned blood. This invented product can greatly raise puncture accuracy, safety and reliability.
Description
What the present invention relates to is the pin that a kind of medical artery and vein puncture is used, and belongs to medical apparatus and instruments.
At present, the diacan that is used in tremulous pulse, venipuncture in China hospitals at different levels all is made of needle stand two parts that the hollow steel needle of straight type links to each other with its afterbody, when tremulous pulse or venipuncture, diacan can be directly used in clinical medical thrust or puncture after the backshank of needle stand connects syringe.When directly puncturing, the blood ejection appears in puncture tremulous pulse regular meeting, does not have the blood back phenomenon because of no negative pressure when the puncture vein, influences puncture accuracy and safety.When behind diacan, connecing syringe and puncture then, because of the influence of syringe is arranged, operator's puncture difficulity of the movment is increased, accuracy, stability are low, and puncture success rate obviously descends.Therefore, above-mentioned two kinds of situations of the prior art all influence the success rate and the safety of artery and vein puncture.
Defective at above-mentioned common diacan existence, the invention provides a kind of Disposable self-sucking arteriopuncture and venipuncture needle capable of preventing puncture fluid from flowing back, it has a root puncture hollow steel needle, its Aculeata is connected with the needle stand that is provided with unidirectional flap valve in, on puncture afterbody of hollow steel needle or needle stand, be equipped with a negative pressure self-priming sacculus, corresponding to offering a side opening on the puncture hollow steel needle of this negative pressure self-priming sacculus or the needle stand.
Described needle stand is made of plastic, in be provided with elastic rubber-plastic composite and make and be bowl-shape unidirectional flap valve, its bowl-shape center offers an otch at least.
The present invention can obviously improve accuracy, the security reliability of artery and vein puncture, and the success rate of puncture is improved greatly, can alleviate patient because of the inaccurate misery of bringing that punctures, and helps carrying out smoothly of doctor's clinical treatment.
Accompanying drawing is a structural representation of the present invention.
The present invention will be described in detail below in conjunction with accompanying drawing: the present invention is mainly by the puncture hollow steel needle 1 of a head band point, and the negative pressure self-priming sacculus 3 that needle stand 2 that joins at its afterbody and draw point 1 afterbody are being nested with is formed.Offer a side opening 4 on puncture hollow steel needle 1, the position of this side opening 4 is positioned at negative pressure self-priming sacculus 3.Negative pressure self-priming sacculus 3 is made by the plastic cement injection moulding, before artery and vein puncture earlier with finger extruding sacculus, the air or the liquid of discharging in the sacculus by the side opening on the draw point 14.In other embodiments, described side opening 4 also can be opened on the needle stand 2, and at this moment, negative pressure self-priming sacculus 3 is nested with on needle stand 2 or draw point and needle stand joint.After the draw point leading section penetrates skin, finger is decontroled, make the inner chamber of puncture draw point 1 be in air-tight state, utilize sacculus nature spring-go to produce negative pressure, at this moment the blood in the sound astillen will be through draw point 1, side opening 4 sucks sacculus 3 automatically, makes the operator can be well understood to the puncture case of successful, so that carry out next step treatment or operation.The needle stand 2 that the afterbody of puncture hollow steel needle 1 joins is made of plastics, this needle stand 2 is actually a plastic pipe sleeve, for avoiding in piercing process, the effusive blood of driven vein sprays or overflows from the draw point afterbody, and the present invention is provided with a unidirectional flap valve 5 of plastics bowl-shape, that the center offers an otch in this plastics needle stand 2.This unidirectional flap valve 5 also can be a cone shape.It can prevent the ejection of arteriovenous blood or overflow, but it can be connected with other device again, and injection or insert guide wire etc. in arteriovenous makes artery and vein puncture and treatment more convenient and safe.
