Abstract
The utility model relates to a disposable sleeve tube optical fiber needle, belonging to the technical field of medical equipment. The utility model is composed of two parts; the first part is an optical fiber needle, comprising an optical fiber needle handle and an optical fiber needle tube; the second part is a sleeve tube injecting needle, comprising a sleeve tube cap head, a sleeve tube, an injecting needle handle and an injecting needle tube. The optical fiber needle of the structure has the advantages of low cost, one-time usage, pollution avoiding and pain because the utility model is injected to human bodies avoiding.
Description
This utility model belongs to technical field of medical instruments.
In He-Ne Intravascular Laser Irradiation on Blood therapy, He-Ne laser must be gone into to carry out the multiple disease of irradiation treatment cardiovascular and cerebrovascular vessel in the blood vessel by the optical fiber needle guide at present.It is metal optical fiber pin and remaining needle that current laser imports blood vessel employed.Metal optical fiber pin has metal needle handle and metal needle tubing, for making both fixing middle metal collars that has; And remaining needle is the injection draw point of by the casing pipe sleeve that a special material is made.This pin operating process is such, press blood-sampling method with remaining needle together with sleeve pipe puncture intravasation, the hand site of puncture, prevent that vessel inner blood from flowing into needle tubing again, simultaneously the needle tubing of keeping somewhere is extracted, sleeve pipe is stayed in the blood vessel, and then will realize in the optical fiber pin threading that laser imports blood vessel.Because optical fiber pin cost height is not that disposable use needs sterilization repeatedly, has blood contamination danger, and is big than draw point pain when the sleeve pipe of remaining needle enters tissue, causes certain misery to the people.
The purpose of this utility model is to provide a kind of disposable sleeve optical fiber pin, to overcome the shortcoming of above-mentioned optical fiber pin.
This utility model is achieved in that it is made of two parts: first is the optical fiber pin, comprises that optical fiber needle handle 1, optical fiber needle tubing 2, optical fiber needle handle are positioned on the optical fiber needle tubing; Second portion is the sleeve pipe entry needle, comprises sleeve cap head 3, sleeve pipe 4, injecting needle handle 5, injection needle 6.
Because the optical fiber pin of this structure seals optical fiber needle handle and optical fiber needle tubing with medical glue admittedly through the injection moulding one-shot forming, greatly reduces cost with former optical fiber pin ratio, is able to disposable use, avoid polluting; Entry needle partly has only injection needle to enter tissue, and sleeve pipe to be positioned on the rear portion of injecting needle handle be that transparent soft tube is used for observing the blood back situation and needn't injects tissue and the misery that causes when having avoided fully injecting.
Describe this utility model in detail below in conjunction with accompanying drawing and embodiment.
Accompanying drawing 1 is a structural representation of the present utility model.
Disposable sleeve optical fiber pin is made of two parts: first is the optical fiber pin, comprises optical fiber needle handle 1, diameter 4.9mm, long 20mm, optical fiber needle tubing 2, diameter 0.7mm, long 69mm, these two parts are fixed on the optical fiber needle handle on the optical fiber needle tubing with medical glue after the injection moulding one-shot forming; Second portion is the sleeve pipe entry needle, and it comprises sleeve cap head 3, sleeve pipe 4, injecting needle handle 5, injection needle 6.Injecting needle handle is a rigid plastics, long 20mm, and diameter 4.2mm, it is installed on the injection needle, this needle tubing is very short, and long 30mm, diameter 1.05mm, sleeve pipe are soft transparent plastic tubes, long 20mm, diameter 3.0mm, it is positioned on the injecting needle handle, its other end sleeve cap head of ining succession.The total length of sleeve pipe entry needle is the length of optical fiber pin.After during use injection needle being inserted human vas, again the optical fiber pin is inserted in the sleeve pipe, make optical fiber needle handle front end insert the sleeve cap head part and be integral with sleeve cap head diameter is identical.
