Furthermore the outside surface of the inner sleeve part has an outwardly extending projection 114 (shown in broken lines) which engages within a track 115 (shown in broken lines) on the inside surface of the outer sleeve 105 including the collar 106.
  • the track 115 is formed by a slot 116 extending through the wall of the collar 106, and a longitudinally extending groove 117 on the inside surface of the outer sleeve 105, the projection 114 extending through the slot 116 and engaging in the groove 117 in order to ensure that there is no relative rotation between the inner and outer sleeves 103 and 105 during contraction of the guard which might result in jamming of the sleeves 103 and 105 due to the fact that such twisting movement will tend to be resisted by frictional engagement of the end of the guard with the skin of the patient.
  • the collar 106 is capable of limited rotation within the recess 107 in the outer sleeve 105, and is provided with an actuating portion in the form of a milled ring 118 which is capable of being manually rotated through a limited angle when the guard is in its extended position in order to unlock the guard.
  • the precise manner in which such unlocking is effected will now be described with reference to Figures 8, 9 and 10 which show side views of the collar 106 in three operational states .of the fitment, the collar 106 being shown withdrawn from the outer sleeve 105 in order to render the operation easier to understand.
  • the slot 116 has a linear portion 119 and a hooked portion 120 within which the projection 114 is held to retain the guard in the extended position when the collar 106 is in the locking position, as shown in Figure 8.
  • the guard may be supplied in this position in which the needle 102 is shielded by the inner sleeve 103 and cannot be accidentally exposed by applying pressure to the end of the inner sleeve 103 in the direction of contracting movement since such pressure will cause the projection 114 to engage a shoulder portion 120A.
  • the milled ring 118 When it is desired to perform an injection the milled ring 118 is turned anti-clockwise to cause the projection 114 to move out of the hooked portion 120 into a temporary retaining portion 121 of the slot 116, as shown in Figure 9.
  • a suitable dose may be delivered to the injection site through the needle, and the needle may be subsequently withdrawn from the injection site.
  • the guard will be gradually returned to its extended position under the action of the spring 108 with the projection 114 travelling back along the linear portion 119 of the slot 116 until it contacts a further guide portion 123 of the slot 116 which results in clockwise rotation of the collar
  • the milled ring 118 may be again rotated to unlock the guard and permit the inner sleeve 103 to be telescoped within the outer sleeve 105 as previously described.
  • Figure 11 shows the collar 106 and inner sleeve 103 only of a variant of the needle fitment 100 just described in which the needle cannot be subsequently re- exposed after an injection has been effected and the guard has been locked in its final extended position.
  • the collar 106 has a slot 130 as shown having a first hooked portion 131 within which the projection 114 is initially held to retain the guard in the extended position, and a second hooked portion 132 within which the projection 114 is held to lock the guard in its extended position after an injection has been effected.
  • the slot 130 has a temporary retaining portion 133 with which the projection 114 is engaged when the milled ring 118 is turned to cause the projection 114 to move out of the hooked portion 131 in order to move the guard into a partially contracted position, as shown in Figure 11, to locate the needle at the intended site of portion 119 of the slot 130 as previously described, but on return of the* projection 114 along the linear portion 119 as the guard moves towards its extended position the - projection 114 is automatically caused to enter the hooked portion 132 and to thereby permanently lock the guard in the extended position.
  • the projection 114 cannot subsequently be moved out of the hooked portion 132 by rotation of the milled ring 118 because of the steepness of the inclined surface 134.
  • Figure 12 shows the collar 106' and the inner sleeve 103 of a further variant which does not include a milled ring permitting manual rotation of the collar and in which the guard is permanently locked in its extended position after use.
  • the slot 130' has a retaining portion 140 within which the projection 114 is held prior to use to retain the guard in a partially contracted position in which the point of the needle 102 projects from the guard to an extent necessary to enable the point of the needle to be located at the intended site of injection, as shown in Figure 12.
  • a protective cap (not shown) will be provided on the end of the inner sleeve 103 to shield the tip of the needle, this cap only being removed immediately prior to the injection being effected. After the injection has been effected and on return of the projection 114 along the linear portion 119 of the slot 130', the projection 114 is automatically caused to enter the hooked portion 141 to permanently lock the guard in the extended position shielding the point of the needle .
  • the slot may include a temporary catch portion into which the .projection may be moved, and/or from which the projection may be released, by manual rotation of the collar in order to temporarily retain the guard in a contracted position in which a substantially greater portion of the needle is exposed than in the partially contracted position.
  • the rotatable collar enables the guard to be automatically locked in its extended position shielding the point of the needle after use, and preferably also prior to use. Furthermore a twisting motion is not imparted to the end of the inner sleeve in use.
  • an instrument may be used with a hollow needle as part of an injection or fluid collection device, such as a hypodermic syringe, a catheter placement unit or the like.
  • the guard may be formed as an integral part of the device, or alternatively it may be formed as an accessory which is attachable to, and possibly subsequently detachable from, such a device.
  • the instrument may also be used with a needle which is not hollow, for example in a lancet device. In this case the needle may simply be supported on an inner part which is displacable within an outer sleeve.

Abstract

Accessoire à ailettes (1) pour aiguille, comportant un dispositif protecteur (2) pour une aiguille (3) et des ailettes souples (4 et 5) que l'on peut fixer à la peau du malade à l'aide de ruban adhésif. Ledit dispositif protecteur (2) possède deux parties (8 et 9) montées mobiles l'une par rapport à l'autre entre une position escamotée, dans laquelle le bout de l'aiguille dépasse du dispositif protecteur, et une position sortie, dans laquelle le bout de l'aiguille est abrité par ledit dispositif protecteur. Les parties (8 et 9) sont guidées par une partie saillante (18) formée sur la partie (8) et destinée à s'engager dans une fente (19) ménagée dans un élément de verrouillage (15) à l'intérieur de la partie (9), et sollicitées dans le sens de la position sortie par un ressort (10). L'élément de verrouillage (15) est monté pivotant dans le sens transversal de l'aiguille entre une position de déverrouillage, dans laquelle la partie saillante peut se déplacer le long de la fente pendant l'escamotage du dispositif protecteur, et une position de verrouillage, dans laquelle le dispositif protecteur est maintenu dans sa position sortie où le bout de l'aiguille est abrité, lorsque ladite partie saillante (18) entre en prise avec une partie épaulée (25) de la fente (19). Un agencement semblable trouve application dans un ensemble à aiguille pour seringues. Ces agencements sont utiles notamment pour empêcher les ponctions cutanées accidentelles dues aux aiguilles non abritées.
