Description
Technical field
The present invention relates to medical instruments field, more particularly to remaining needle is administered in a kind of disposable safe positive pressure front end.
Background technology
Remaining needle is also known as venous catheter needle, its use can reduce infant pain caused by due to venipuncture repeatedly and
To the fear having an injection, mitigate the impatience of parent, is convenient for clinical application, mitigates the workload of clinical nurse.Remaining needle is grasped
Make easy, be suitable for the puncture at any position, be clinically able to commonly used, the core building block of remaining needle includes indwelling
Conduit/casing in the blood vessels and guiding puncture needle core, in use, conduit and needle core are punctured into together it is intravascular, to leading
After pipe fully enters blood vessel, needle core is withdrawn, by catheter retaining in the blood vessels to carry out infusion treatment.Indwelling in the prior art
Needle is easy to result in blockage the generation of phenomenon because palm be bent, or the phenomenon that thrombus occurs and influence the flow velocity being infused, Bu Nengzheng
Often administration, increases the pain of patient.
Invention content
For above-mentioned deficiency in the prior art, the present invention provides a kind of disposable safe positive pressure front ends, and indwelling is administered
Needle, it is compact-sized, prevent blood backflow in extension tube, can not by extraneous material and pipeline within the indwelling phase activity deformation shadow
Ring the possibility for generating liquid flowing.
In order to reach foregoing invention purpose, the technical solution adopted by the present invention is：
Remaining needle is administered in a kind of disposable safe positive pressure front end, including draw point and holds needle handle, including：Transparent threeway, vacuum pump and
One end of fixed rope, the transparent threeway is fixedly connected with draw point, one end with draw point point-blank of the transparent threeway
It is interior to be equipped with transparent isolation plug, it is inserted into the transparent isolation plug and holds needle handle, the transparent threeway is in 45-60 with draw point extended line
One end of degree angle is connected with extension tube, and the one-hand clip for preventing liquid medicine flow is equipped in the extension tube, defeated in stopping
During liquid, the other end of the extension tube is equipped with connector, and the connector connects vacuum pump, and there are three port, institutes for the vacuum pump
Stating vacuum pump to be equipped with valve with the one end of jointing one end point-blank, the vacuum pump other end is equipped with end
Cap；
The fixed rope winds transparent threeway, and transparent threeway is fixed in wrist, and the fixed rope is equipped with fastener Assembly.
Further, the needle handle of holding is equipped with anti-skid bulge.
Further, during infusion, the other end of the extension tube connects infusion tube interface.
Beneficial effects of the present invention are：
Draw point and transparent three-way pipe are fixed in gesture and facial expression by the fixed rope of the present invention, and when preventing patient from moving hand, draw point is far from hand
Face, one-hand clip prevent in infusion process, there is blood backflow in extension tube, can not be by extraneous material and pipeline within the indwelling phase
Movable deformation effect generates the possibility of liquid flowing.During stopping being infused, vacuum pump is depressed into residual liquor in extension tube
Blood can prevent blood backflow, prevented also from bacteria breed, under vacuum state, avoid air and impurity from entering, reach daily
Health and protective action.
