REMOVAL OF NEEDLE SHIELD FROM SYRINGES AND AUTOMATIC INJECTION DEVICES

摘要

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.

主权项

1. An apparatus for removing a needle shield from a syringe, comprising:
a tubular member for enclosing the needle shield coupled to the syringe; one or more cap engagement mechanisms provided at a distal end of the tubular member and configured for engagement with a distal cap provided for covering a distal end of the syringe; and one or more shield engagement mechanisms provided at a proximal end of the tubular member and configured for engagement with the needle shield; wherein, when the apparatus is pulled away from the syringe, the one or more shield engagement mechanisms exert force against the needle shield to remove the needle shield from the syringe.
