Removal of needle shield from syringes and automatic injection devices
First Claim
1. A needle shield remover for removing a needle shield from a syringe, comprising:
- a cap having an open end and a closed end with a centrally located aperture,a tubular needle shield remover disposed within the cap for removing a needle shield from a syringe, the tubular needle shield remover having a proximal tubular portion having a first outer diameter and a distal tubular portion having a second outer diameter less than the first outer diameter,a platform structure projecting longitudinally from the distal tubular portion of the tubular needle shield remover along a longitudinal axis toward the aperture, anda cap engagement mechanism projecting radially outwardly from the platform structure to cooperatively engage the tubular needle shield remover with the cap via the aperture.

Abstract
Exemplary embodiments provide a needle shield remover that reliably engages with a distal cap of an automatic injection device and with one or more needle shields coupled to a syringe of the device. When a user removes the distal cap, the needle shield remover reliably removes the needle shields (e.g., a soft needle shield and a rigid needle shield) from the syringe, thereby exposing the injection needle for performing an injection. In an exemplary assembly method, a needle shield remover is engaged to a needle shield coupled to a syringe, prior to insertion of the syringe and needle shield remover assembly into a housing of the device. This exemplary assembly method allows visual inspection, outside the housing of the device, to ensure that the needle shield remover is correctly and reliably engaged to the needle shield before the syringe and needle shield remover assembly is inserted into the housing.
