Definitions

  • TITLE PROTECTIVE DEVICES FOR CANULAS
  • This invention concerns the protection of the tips of the canulas (commonly called needles) used in 5 hypodermic syringes and in the equipment used to take blood samples and donations.
  • the covering of the end of a canula is effected with a cap or cover.
  • protective caps have been described in the specification of U.K. patent No 1,514,725 and in the specifications of U.S. patents Nos 4,248,246 and 4,629,453.
  • the cap or cover is normally positioned over the end of the new and sterile canula, is removed prior to the use of the canula, and is then replaced after the canula has been used.
  • the cap or cover usually has a small aperture into which the end of the canula must be fitted and it is not uncommon (even when a protective flange is fitted to the cover, as in the case of the invention of U.S. patent No 4,629,453) for the user of the canula to experience some difficulty in aligning this aperture with the end of the canula, and for the user to be pricked by the canula in the course of attempting to cover its tip.
  • This objective is achieved by providing a cover for a canula that is removeable from and replaceable over
  • the cover for the canula comprises a generally tubular sheath which is adapted to fully cover the canula and which is provided with an
  • a protective device for a canula comprising an elongate, substantially rigid,. - ⁇ 25 tubular sheath adapted to fit over the entire canula, characterised in that a) the sheath has an elongate slot formed therein and extending from one end thereof for at least part of the length thereof, the slot having a width which is greater than the diameter of the canula; and b) said one end of the sheath is adapted to fit- on to the support for the canula.
  • the support for the canula may be the conventional needle support of a hypodermic syringe or the end of a blood sampling flexible tube, in which case it is preferred that an annular retaining member, adapted to securely grasp said one end of the sheath, is fitted over the support for the canula.
  • the support for the canula may be provided with a cap which is firmly affixed (usually by manual pressure) over or into the end of the support for the canula, this cap having an aperture therein through which the canula projects.
  • the end of the sheath which is .remote from the tip of the canula (that is, the end of the sheath from which the slot extends) will then be a press fit over or into this cap.
  • the sheath and the annular retaining member may be connected by a short strap or cord, or a hinge, which ensures that the sheath remains connected to the needle support while the canula is used, thus preventing misplacement of the protective sheath by the user of the canula.
  • the length of the slot in the sheath will be approximately equal to the length of the canula.
  • Figure 1 is a perspective sketch of the present invention.
  • Figure 2 is a sectional view of an annular retaining member that may be used to secure the device of Figure 1 around a canula.
  • Figure 3 shows an alternative embodiment of the present invention fitted to a hypodermic syringe.
  • Figure 4 illustrates the removal and replacement of the protective sheath of the device illustrated in Figure 3.
  • Figure 5 is a perspective sketch of another embodiment of the present invention.
  • the protective device illustrated in Figure 1 comprises a substantially rigid tubular member 10 which is tapered towards a closed end 11 and has an open end 12 which is adapted to fit over or into a support for a canula.
  • the tubular member 10 has a slot 16 extending from the end 12 for a distance which, in the illustrated embodiment, is substantially equal to the length of the canula that it protects.
  • the slot has a width which is at least slightly greater than the outside diameter of the
  • the tubular member 10 may be made from any suitable material which is rigid enough to be self supporting in the configuration illustrated in Figure 1. A number of plastics materials meet this requirement.
  • the end 12 of the protective device illustrated in Figure 1 is firmly held in its protective position around a canula by an annular retaining member which fits on to the needle support.
  • annular retaining member is illustrated in Figure 2.
  • the retaining member 17 of Figure 2 is moulded as a single article from a resilient material, such as neoprene or a flexible and resilient plastics material. It comprises an annular body portion 14 from which an arm 15 extends.
  • the arm 15 is generally C-shaped in cross-section, with the top of the "C" defining a circular aperture that is greater in diameter than the internal diameter of the body section 14.
  • the tubular member 10 is detached from the needle support on which it is mounted by a manual force applied at or near end 12 of the tubular member 10.
  • the tubular member 10 is moved a distance away from the needle support until the tip of the canula can be passed through the slot 16.
  • a sideways movement of the tubular member 10 (as shown in Figure 4, which is discussed below) enables the whole of canula to pass through the slot " 16 as the tubular member 10 is removed.
  • Replacement of the protective tubular member 10 is by the reverse of this sequence of steps.
  • the retaining member may be connected to the sheath 10 by a flexible strap, if desired, to prevent the removal of the sheath from the region of the canula.
  • FIG. 3 and 4 A variation of the combination of the protective sheath 10 of Figure 1 and the retaining member 17 of Figure 2 is illustrated in Figures 3 and 4.
  • a cap 20 is a tight fit over the needle support.
  • the cap 20 has an aperture in it to permit the canula 13 to project through the cap.
  • the end of the sheath or tubular member 10 is a tight fit over the cap 20, and is removed from cap 20 in the same way as the tubular member 10 of Figure 1 is removed from its associated needle support or retaining member 17.
  • the protective devices shown in Figures 1, 2 and 3 are designed to be moulded as a single item from a suitable plastics material.
  • Figure 5 illustrates another embodiment of the present invention, consisting of a tapered, tubular sheath 50 having a slot 56 formed in it.
  • a thickened end region 59 of the sheath 50 has a strap 58 affixed to it.
  • Strap 58 connects the region 59 to a ring 54 which is adapted to be a tight fit over a support 55 for a canula 53 (shown in dashed outline to illustrate the way in which this embodiment of the invention is used).
  • Flutes or ridges 57 assist in the manual gripping of the sheath 50.
  • the operation of the embodiment of Figure 5 is essentially the same as the operation of the embodiment of Figures 3 and 4, and further explanation thereof is not necessary.
  • sheath 50, strap 58 and ring 54 is designed to be moulded as a single item from a suitable plastics material, in which case the strap 58 will apply a bias to the sheath or cover 50 into the position shown in Figure 5. In this position, the cover will not interfere with the use of the canula to administer a drug or take a blood sample.
  • all the protective devices illustrated and described above are suitable for use with canulas (needles) mounted in syringes and in the ends of tubes, whether for administering a drug or a drip, or for taking samples of blood or other liquid from a human or animal body or from a storage container of blood or other liquid.
  • the present invention may also be adapted for use with catheters and other body probes if protection against contact with the ends of such probes is required.

Abstract

Un dispositif protecteur pour canules (13, 53) se compose d'une enveloppe généralement tubulaire (10, 50) ayant une fente (16, 56) s'étendant depuis l'une de ses extrémités. L'enveloppe (10, 50) recouvre complètement la canule. La fente (16, 56) est plus large que le diamètre extérieur de la canule, de telle sorte que l'enveloppe peut être retirée de la canule et replacée sur celle-ci, sans que les mains de l'utilisateur de la canule s'approchent de la pointe de la canule. L'enveloppe peut être connectée par une attache (18, 58) à un couvercle (20) ou une bague (54) disposés sur le support de la canule.
