Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable use lucifuge venous detaining needle.
Background technology
We know, venous detaining needle is a kind of medical apparatus and instruments that is used for the venous indwelling transfusion, it mainly includes remaining needle sleeve pipe, casing seat, puncture needle tubing, connecting leg, transfusion three way cock assembly, the sleeve pipe rear end is connected with casing seat, sealing-plug also is housed in the casing seat, the puncture needle tubing was inserted sealing-plug hermetically, was positioned at whole remaining needle sleeve pipe, and casing seat is connected with transfusion three way cock assembly by connecting leg.After medical personnel use venous indwelling at the patient's vein vascular puncture, need the puncture needle tubing is extracted from casing seat rear end and remaining needle sleeve pipe, then comparatively softish sleeve portion is kept somewhere in the patient's vein blood vessel, carried out continuously to the patient or transfusion discontinuously by the remaining needle sleeve pipe.When using venous indwelling to infuse, have many medicines to need lucifuge, otherwise curative effect so just can not be well brought into play in the very easily variable color under ultraviolet illumination of these medicines, degeneration, generation decomposition etc., even be threatened patient's body health at patient's vein.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, safe and effective, stable performance, easy to use, have the lucifuge effect, avoid the disposable use lucifuge venous detaining needle that contacts of medicinal liquid and lucifuge composition fully.
The technical scheme in the invention for solving the above technical problem is: a kind of disposable use lucifuge venous detaining needle; mainly include the remaining needle sleeve pipe; casing seat; the puncture needle tubing; connecting leg; transfusion three way cock assembly; the sleeve pipe rear end is connected with casing seat; sealing-plug is housed in the casing seat; the puncture needle tubing was inserted sealing-plug hermetically; in the remaining needle sleeve pipe; casing seat is connected with transfusion three way cock assembly by connecting leg; it is characterized in that: described connecting leg is made or by the polyurethane internal layer by polyurethane internal layer and lucifuge layer are compound; the lucifuge layer; outer compound making, described casing seat; the outer surface of the threeway of transfusion three way cock assembly is coated with the lucifuge protective layer respectively.
Calparine cap and protective cap on this utility model transfusion three way cock assembly all are to be made by the lucifuge material.
The said polyurethane of this utility model (PU) internal layer is a medical grade material, can not react with medicinal liquid; Said skin is made for the medical grade PVC material, and said lucifuge layer is that black or brown opaque lucifuge PVC material are made.
This utility model venous detaining needle is because each parts that contacts with medicinal liquid all are to adopt multi-layer compound structure two-layer or that three-layer plastic is composited.The lucifuge layer is that black or opaque lucifuge plastics such as brown are made, and has the lucifuge effect, can reach the lucifuge effect of lucifuge medicine requirement.Against existing technologies, when medical personnel need the medicinal liquid of lucifuge at infusion, ultraviolet is stopped by the lucifuge layer fully, avoided the possibility of medicine variable color under ultraviolet illumination, degeneration, generation decomposition etc., make medicine give full play to curative effect, assurance patient's body health, the more important thing is that this utility model avoided contacting of medicinal liquid and lucifuge composition fully, it is rational in infrastructure, easy to use, safe and effective, stable performance, to improving the transfusion work efficiency and strengthening the infusion treatment effect all is very effective, is a kind of ideal disposable use lucifuge venous detaining needle.Need to be specially adapted to the medication infusion of lucifuge to use.
