Description
Technical field:
This utility model relates to transfusion technical field of medical instruments, is specifically related to a kind of novel safe type retention needle.
Background technology:
The use of remaining needle, infant can be reduced because of venipuncture repeatedly and the misery caused and to the fear of having an injection, alleviate the impatience of the head of a family, be convenient to clinical application, and urgency, critical patient rescue medication, alleviate the workload of nurse, reduce infant pain, thus venous detaining needle is in wide clinical application, in the face of this specific group of infant, the problem that the length of detaining time of intravenous indwelling needle and the comfortable nurse of becoming of infant and the head of a family pay close attention to the most is also the prerequisite of the mark that successfully uses of remaining needle and popularization.
Venous detaining needle is the conventional medical apparatus and instruments in nursery work, have easy to use, reduce the effect to patient's puncture time, thus repeated localised puncture when decreasing clinical transfusion, reduce the workload of the painful and clinical nursing staff of the puncture of patient, thus current clinical in obtain extensive use.
In existing venous detaining needle, generally comprise: puncture needle, remaining needle and transfusion catheter.During use, first, puncture needle UNICOM remaining needle is inserted the injection position of patient by user, then, by puncture needle guiding, remaining needle is imported patient vessel, finally, is extracted out by puncture needle, remaining needle is stayed in patient vessel, and fixes with pad pasting of applying ointment or plaster.
But existing remaining needle, there is the problem of blood backflow, easily causes blood coagulation, obstruction conduit.
Utility model content:
The purpose of this utility model is to provide a kind of novel safe type retention needle, and its structure is simple, novel in design, is provided with folding plugging device, can be good at the tube for transfusion of closed remaining needle in the middle of remaining needle extension tube, avoids blood flow to reflux and condenses, obstruction conduit.
In order to solve the problem existing for background technology, this utility model is by the following technical solutions: it comprises remaining needle body, hold pin hands handle, extension tube, anti-return folding stand, rotating shaft, folding stand, positive pressure connector, drug injection mouth, transfusion one-way interface, the front end of described remaining needle body is provided with holds pin hands handle, the rear end of remaining needle body is connected with extension tube, the middle card of extension tube is connected to anti-return folding stand, the afterbody of anti-return folding stand is connected with folding stand by rotating shaft, the afterbody of extension tube is connected with positive pressure connector, the side of positive pressure connector is provided with drug injection mouth, the afterbody of positive pressure connector is provided with transfusion one-way interface.
As preferably, the syringe needle of described remaining needle body comprises metal and interts pin and transparent tube composition.
As preferably, the lateral wall of described folding stand is provided with clamping tongue.
The beneficial effects of the utility model: its structure is simple, novel in design, in the middle of remaining needle extension tube, be provided with folding plugging device, can be good at the tube for transfusion of closed remaining needle, avoid blood flow to reflux and condense, obstruction conduit.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Reference numeral: remaining needle body 1, hold pin handle 2, extension tube 3, anti-return folding stand 4, rotating shaft 5, folding stand 6, positive pressure connector 7, drug injection mouth 8, transfusion one-way interface 9, thoroughly name pipe 10, metal intert pin 11, clamping tongue 12.
