DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to needle housings and more particularly to such housings as might accommodate a needle used in the medical profession or in personal drug administration so that the physician, surgeon or other needle operator might be protected from injury by the needle after its use.
The danger of injury and possible infection with the HIV or hepatitis B virus to medical practitioners using needles in the normal course of their business is well documented. Further, persons who are in the habit of administering drugs to themselves run a severe risk of contacting either the specified viruses, or indeed contacting other viruses if a needle, once used, is reused in an unsterilised form. Various attempts have been made to provide a safe system for disposal of such needles once used but such prior proposals have had deficiencies.
OBJECT OF THE INVENTION
It is an object of this invention to provide .apparatus for housing used surgical needles in a substantially safe manner.
SUMMARY OF THE INVENTION
This invention in one broad form provides a housing for said housing comprising a base adapted to be located on a substantially flat surface, a body adapted for location therein of a needle, a skirt integral with or dependent from the end of the housing body remote from the base thereof and a securement means adapted to retain within the body of said needle housing, a needle once located therein.
It is preferred that the base of the needle housing of this invention be circular and be provided on its underside with a friction surface of toughened rubber for example having anti-slip properties, or alternatively, any anti-slip adhesive means such as a pad impregnated with adhesive material, that pad being covered with a removable plastics or other shield. For example, the removable plastics or other shield may be a hot melt resin rubber base tape. Once the plastics shield is removed from the adhesive material, the housing base may be located on or secured to a flat surface such that when the housing itself is held by the left hand (of a right handed person) the housing will resist movement relative to the base on which it is located, although the housing might be removed by hand pressure from that base after a needle is secured in the housing.
It is further preferred that the aforesaid skirt located at the opposite end of the needle housing from the base, be annular and be integral with the housing.
It is further preferred that the securement means be provided by a rib protruding within the housing in an annular manner and adapted to prevent removal therefrom of a used needle, once that used needle is located In the needle housing of this invention.
It is further preferred that the securement means be adapted to frictionally engage an annular or frusto-conical peripheral surface of a needle boss in which the needle is supported. Such frictional engagement is aimed at retaining the needle boss such that prior to use, the needle boss and needle will be securely retained within the housing.
It is further preferred that an O-ring or any other annular ring be provided, being adapted to locate on the upper surface of the skirt and in contact with the needle boss prior to the needle's use. Such an annular ring prevents accidental full insertion of the needle into the housing prior to its use. Upon first removal of the needle from the housing, the annular ring may be discarded.
It is further preferred that a luminous band or other indicator be provided on the upper surface of the skirt. Such a luminous band may enable a user to guide a needle into the housing in conditions of poor lighting.
