Definitions

  • This invention relates to an improved method and apparatus for the disposal of hypodermic needles and more particularly to the disposal in a safe manner with little or no likelihood of any person being pricked or otherwise contaminated by the needle.
  • a major problem associated with the disposal of hypodermic needles is the risk of "needle-stick" injuries, where an exposed needle pierces the skin of an individual handling the needle after use, potentially causing infection of that individual.
  • Numerous proposals for alleviating the problem have been made, including the provision of a sheath into which the needle can be inserted from one end and within which the needle can be frictionally captured, so that removal of the needle once inside the sheath is difficult.
  • a difficulty with this sort of sheath is that the needle is to be inserted from one end into the tubular sheath, and a hand may be needed to either hold the sheath or simply to steady the sheath if it is supported in a rack, and an accidental bumping or simply careless placement may cause the steadying hand to be pricked by the needle.
  • hypodermic needle holder that is automatic in operation and which merely requires the user to insert the needle while attached to the syringe and withdraw the syringe from the needle, should the user require to do so, with the needle being safely located within the holder.
  • a hypodermic needle holder adapted to capture a needle while said needle is attached to a syringe, said holder comprising a sheath having a longitudinally open recess adapted to accommodate a portion of the needle including the sharpened end, said recess being adapted for entry by said portion of the needle by a radial movement of the needle into said recess, said holder including locking means adapted to lock said needle in place so that the said portion of the needle is captured within the recess.
  • FIG. 1 shows the holder and the needle approaching the holder
  • FIG. 2 shows the hand position with the needle approaching from the side
  • FIG. 3 shows an end view with the needle barrel deflecting the locking flaps
  • FIG. 4 shows the needle barrel held captive
  • FIG. 5 shows an end view of the needle barrel held captive.
  • the holder which, for convenience will be called a sheath 1 , has a U-shaped body 2 having a recess 3 surrounded by a flange 4.
  • the flange 4 serves to assist in the placement of the needle within the recess 3, and the portion of the recess closest to the flange are tapered to assist in this placement.
  • the body 2 is closed and sufficiently long to accommodate the range of needles to be retained within it, and at the other end 6, is provided with resiliently deformable locking flaps 7.
  • the end 6 is closed by a wall 8 with a slot 9, the width of the slot 9 is less than the diameter of flange 10 on the needle barrel 11 , but sufficiently wide to accommodate the end of the syringe to which the needle barrel is attached.
  • the slot has a generally inwardly sloping upper portion to assist with the placement of the needle into the recess 3.
  • the bottom of the sheath 1 has a handle flange 12 to provide a grip so that the sheath can be easily and safely handled.
  • the locking flaps 8 have a length generally as long as the needle barrel 11. In the rest position the locking flaps 7 slope into the holder so that the needle barrel 11 can enter the holder; the locking action of the locking flaps 7 will be described in more detail below
  • the holder 1 is held by the handle 12 in one hand, and the syringe 14 by the other hand.
  • the needle and syringe is presented to the holder with the needle extending away from the user with the needle in line with the recess 3.
  • Shown in FIG. 1 is the needle barrel approaching the holder and entering the slot ready to deflect and pass the locking flaps.
  • the needle barrel 11 is shown deflecting the locking flaps 7.
  • the locking flaps are moulded from a resilient material, and as can be seen from FIG. 1 they are tapered so that they are most flexible where the needle barrel 11 comes in contact with them.
  • the locking flaps are generally as long as the needle barrel itself, the flaps hold the needle in the recess and prevent the needle within the recess from tilting axially and thereby to expose the sharpened end of the needle for possible contact with the handler of the disposed needle. Also it is to be realized that at the end of the locking flaps adjacent to the recess there is a further wall 15 with a further slot 16 which is of a width less than the end of the needle barrel while allowing the needle to pass therethrough. The distance between the walls 8 and 15 is such as to provide for a close fit of the needle barrel and when in place by reason of this arrangement the needle is secured in the recess 3 by the retention and locking of the needle barrel 11.
  • Wall 8 has around the non-receiving portion of its periphery a supporting flange 17 to support the free end of the barrel 11.
  • the upper edge of the supporting flange 17 is shown by broken line in FIGS. 1 and 5.
  • the needle barrel 11 is also supported by the upper surface of andle 12, which slopes complementary to and adapted to support the tapered needle barrel 11.
  • FIG. 4 shows the syringe being removed from the needle barrel with the needle securely locked in the holder.
  • the flange 10 at the end of the needle bears against wall 8 when the syringe is pulled axially away from the holder.
  • the end of the syringe onto which the needle is fitted can slide through slot 9 and the needle can thus be removed whereas the syringe stays captured within the holder.
  • the syringe with holder retaining the needle can be disposed together, without first separating the needle from the syringe, although for compactness usually the syringe would be separated from the needle.
  • the preferred embodiment of the present invention is a versatile unit which can be of use anywhere a hypodermic needle is used, whether it be in a hospital, doctor's surgery, at an accident scene, in the home or wherever a patient has to be treated and can be kept in the coat pocket of an individual ready for use.
  • the holder completely accommodates the hypodermic needle after it has been used, and thereby prevents the needle from piercing the skin of any individual who subsequently handles the needle perhaps for disposal purposes.
  • the holder has a recess to take needles of various lengths, and the needle approaches the opening oriented generally in line with the recess and from a direction generally transverse to the opening, and thus ensures that the point of the needle is directed away from the user, particularly with the hand held units.
  • the needle Once inserted the needle is mechanically locked to ensure safe retention of the needle, and this mechanical locking makes it possible to remove the syringe from the needle without any possibility of the needle becoming unsheathed. Although it may be possible to forcibly remove the needle from the recess 3 once locked in, this locking inhibits persons such as may have a drug habit from attempting to scavenge the needle for their own use.
  • the holder may be a single hand held unit, a multiple recess hand held unit, a portable receptacle incorporating either a single recess or a multiple of recesses, or a bench or wall or other surface mounted unit.
  • the locking means need not take the form of the locking flaps and need not lock onto the barrel of the tubular portion of the needle, the needle itself can also be locked into place.
  • the sheath need not be closed at end 5 but need only be sufficiently long to shield the range of needles intended to be retained within it.
  • the body of the sheath need not be U-shaped, provided that it has a recess of such dimensions sufficient to accommodate the range of needles to be stored within it.
  • the sheath need not be hand held but as an alternative may be retained in a non-hand held device such as a rack or other bench held retention device.

Abstract

Un porte-aiguille pour des aiguilles de seringue hypodermiques utilisées comprenant une gaine (1) possédant un corps (2) en forme de U avec un encastrement (3) dans la gaine (1) accessible sur un côté pour recevoir une aiguille (13). Le réceptacle comprend des ailettes de blocage (7) se prolongeant vers l'intérieur à partir des côtés du porte-aiguille et formées dans l'encastrement (3) de manière qu'en déposant l'aiguille (13), les ailettes de blocage (7) s'écartent des côtés de la gaine (1) pour permettre à l'aiguille (13) de pénétrer dans l'encastrement (3). Les ailettes (7) alors empêchent de retirer l'aiguille (13) de la gaine (1) étant donné que les ailettes de blocage (7) viennent en butée contre le cylindre (11) de l'aiguille (13). L'une des extrémités (6) de la gaine (1) présente une fente (9) d'une largeur inférieure au cylindre (11) de l'aiguille (13). Ceci permet à la seringue (14) de se séparer de l'aiguille (13) en la retirant de la gaine (1).
