Abstract
The utility model relates to a multi-layer compound type lightproof intravenous infusion needle comprising an intravenous needle tube, a needle handle, a catheter and a needle stand, wherein the catheter and the needle stand are respectively formed by compounding an inner layer, an outer layer and a lightproof middle layer. The inner layer and the outer layer are made of medical grade plastics. The lightproof middle layer is made of non-transparent lightproof plastics. The utility model avoids the contact of liquor and a lightproof component. The utility model has a reasonable structure and stable performance and is safe and effective. The utility model is especially suitable for infusing and puncturing a medicine needing to be lightproof.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of MULTILAYER COMPOSITE type lucifuge venoclysis needle.
Background technology
We know that disposable use venoclysis needle is the medical apparatus and instruments of using always, and it generally comprises vein needle tubing, needle handle, conduit, needle stand.When being used, some medicines of infusing under must the lucifuge condition need add native silver or black cloth parcel, trouble very in the clinical use, and careless a little, just may cause the drug effect reduction, lost efficacy even become noxious substance.At present, special lucifuge venoclysis needle is arranged also, be mainly used to lucifuge infusion medicinal liquid clinically, prevent that the infusion process herb liquid from decomposing under ultraviolet irradiation.Existing lucifuge venoclysis needle generally is to increase the lucifuge agent in the material the inside of conduit, needle stand, reach the effect of lucifuge, the lucifuge agent very easily comes off under the effect of medicinal liquid (particularly acid or alkaline medicinal liquid) or other reaction, causes the lucifuge venoclysis needle dangerous.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, stops contacting of medicinal liquid and lucifuge composition, provides a kind of rational in infrastructure, safe and effective, and stable performance has the MULTILAYER COMPOSITE type lucifuge venoclysis needle of lucifuge effect.
The technical scheme in the invention for solving the above technical problem is: a kind of MULTILAYER COMPOSITE type lucifuge venoclysis needle, comprise vein needle tubing, needle handle, conduit, needle stand, it is characterized in that conduit, needle stand are respectively by internal layer, skin with the lucifuge intermediate layer is compound makes.
The said internal layer of this utility model, skin are made for the medical grade plastics.Said lucifuge intermediate layer is that opaque lucifuge plastics are made.
This utility model is because each parts that contacts with medicinal liquid all are the multi-layer compound structures that adopts three-layer plastic to be composited.Internal layer, skin are made for the medical grade plastics, can not react with medicinal liquid.The lucifuge intermediate 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, this utility model has been avoided contacting of medicinal liquid and lucifuge composition fully, and it is rational in infrastructure, and is safe and effective, stable performance.Need to be specially adapted to the medication infusion puncture of lucifuge.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the section enlarged diagram of this utility model conduit.
1. protective sleeves among the figure, 2. vein needle tubing, 3. needle handle, 4. conduit, 5. needle stand, 6. helmet, 41. conduit lucifuge intermediate layers, 42. conduit internal layers, 43. catheter outers.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As can be seen from Figure 1, a kind of MULTILAYER COMPOSITE type of this utility model lucifuge venoclysis needle comprises vein needle tubing 2, needle handle 3, conduit 4, needle stand 5, helmet 6 etc., carries out the venous transfusion puncture.2 its effects of vein needle tubing are that human vein is inserted in puncture, and its rear portion is provided with needle handle 3, and the outside is provided with protective sleeve 1.Connect with conduit 4 between vein needle tubing 2 and the needle stand 5, needle stand 5 is used for connecting transfusion device etc.Needle stand 5 is by 6 sealings of latex helmet.Above-mentioned composition structure belongs to prior art, no longer describes in detail.
Characteristics of the present utility model are: conduit 4, needle stand 5 are respectively by internal layer, skin with the lucifuge intermediate layer is compound makes.
The said internal layer of this utility model, skin are made for the medical grade plastics.The medical grade plastics can be polypropylene, the medical grade raw materials such as PVC, TPE of medical grade.Said lucifuge intermediate layer is that opaque lucifuge plastics are made, and opaque lucifuge plastics adopt the raw material that adds the lucifuge agent, can be the black of lucifuge or brown PVC, polypropylene material.
As seen from Figure 2, conduit 4 is by conduit internal layer 42, catheter outer 43 and conduit lucifuge intermediate layer 41 compound making, and it can adopt three-layer co-extruded compound making.
This utility model needle stand 5 also adopts internal layer, skin and the lucifuge intermediate layer is compound makes.
This utility model is because each parts of contact with medicinal liquid all are employing internal layer, skins and the lucifuge intermediate layer is compound makes, internal layer is made for the medical grade plastics, can not react with medicinal liquid, the lucifuge intermediate layer is that black or opaque lucifuge plastics such as brown are made, has the lucifuge effect, can reach the lucifuge effect of lucifuge medicine requirement, the skin that contacts with the patient is the raw material of no lucifuge agent.Can avoid decomposition and the destruction of the light of some wavelength effectively, also avoided contacting of lucifuge agent and medicine, stop contacting of medicinal liquid and lucifuge composition, fundamentally avoid of the influence of lucifuge composition medicinal liquid to medicinal liquid.It need to be specially adapted to the medication infusion puncture of lucifuge.
Claims (4)
1. a MULTILAYER COMPOSITE type lucifuge venoclysis needle comprises vein needle tubing, needle handle, conduit, needle stand, it is characterized in that conduit, needle stand are respectively by internal layer, skin with the lucifuge intermediate layer is compound makes.
2. MULTILAYER COMPOSITE type lucifuge venoclysis needle as claimed in claim 1 is characterized in that said internal layer and outer makes for the medical grade plastics.
