Sheath remover device
First Claim
1. A sheath remover for use in removing a sheath from a needle of a syringe prior to an injection, said sheath remover comprising:
- an elongate sheath passageway having a sheath capture region at a first end and configured to allow passage of a sheath along the passageway away from the sheath capture region to exit the passageway at a second end to be released from the sheath remover, the second end being opposite to the first end;
a sheath gripping arrangement disposed in said sheath capture region and adapted in use to be engageable with a needle sheath when offered up thereto and to grip the sheath sufficiently to enable to the sheath remover to remove the sheath from the needle as the sheath remover is pulled away from the syringe,wherein said sheath remover is adapted such that, in use, a sheath already disposed in the sheath capture region is pushed along the passage, away from the sheath capture region, when the sheath remover is offered up to, and engages a subsequent sheath.

Abstract
A sheath remover device is of elongate tubular form having a sheath capture region at one end and a passage along which a captured sheath may pass from the capture region. A plurality of latching fingers, each with an internally directed latch, are equi-spaced in the capture region. Two further inwardly directed latches are on the cut out regions. The sheath remover is designed so that, a sheath already disposed in the sheath capture region is pushed along the passage away from the sheath capture region when the remover is offered up to and engages the subsequent sheath. The spacing of the latches and is such that the earlier sheath is not released from latches until the latches have securely engaged in the subsequent sheath, thereby providing an indication of secure engagement of the subsequent sheath. The sheath remover may also be used as a cap and/or a cocking rod.

18. An injection device assembly comprising a housing, a syringe locatable within the housing in use and having a needle covered by a removable sheath, and a sheath remover for removing said sheath, said sheath remover comprising:
-
an elongate sheath passageway having a sheath capture region at a first end and configured to allow passage of a sheath along the passageway away from the sheath capture region to exit the passageway at a second end to be released from the sheath remover, the second end being opposite to the first end; a sheath gripping arrangement disposed in said sheath capture region and adapted in use to be engageable with a needle sheath when offered up thereto and to grip the sheath sufficiently to enable to the sheath remover to remove the sheath from the needle as the sheath remover is pulled away from the syringe, wherein said sheath remover is adapted such that, in use, a sheath already disposed in the sheath capture region is pushed along the passage, away from the sheath capture region, when the sheath remover is offered up to, and engages a subsequent sheath. - View Dependent Claims (19, 20)

21. A sheath remover for use in removing a sheath from the needle of a syringe, prior to an injection, said sheath remover comprising:
-
an elongate sheath passageway having a sheath capture region at a first end and configured to allow passage of a sheath along the passageway away from the sheath capture region to exit the passageway at a second end to be released from the sheath remover, the second end being opposite to the first end; a first sheath gripping arrangement disposed in said sheath capture region and adapted in use to be engageable with a needle sheath when offered up thereto and to grip the sheath sufficiently to enable to the sheath remover to remove the sheath from the needle as the sheath remover is pulled away from the syringe and a second sheath gripping arrangement within said passageway spaced from said first mentioned gripping arrangement and designed to slideably engage a sheath that is being moved further into the passageway by introduction of a subsequent sheath into the sheath capture region, wherein in use, a sheath already disposed in the sheath capture region is pushed along the passage, away from the sheath capture region, when the sheath remover is offered up to, and engages a subsequent sheath. - View Dependent Claims (22)
