A pen needle and a method of using the pen needle. The pen needle includes a housing, a needle carrier in the housing supporting a needle, a distal shroud positioned around the needle within the housing, a distal compression spring positioned around the needle between the needle carrier and the distal shroud, a proximal shroud positioned around the needle within the housing, and a proximal compression spring positioned around the needle between the needle and the proximal shroud. The proximal shroud is movable between a first position, in which the proximal shroud engages the distal shroud to hold the distal shroud in engagement with the housing, and a second position in which the proximal shroud is disengaged from the distal shroud allowing the distal shroud to move in a distal direction to project from the housing and surround a distal end of the needle.

Medical injector

An auto-injector for receiving and operating a syringe. The auto-injector includes a housing for receiving the syringe, the housing comprising a main body and a hinged door operable into an open position and a closed position. The syringe is receivable within the housing when the hinged door is in the open position. At least one charging link is connected between the main body and the hinged door, wherein a connection of the at least one charging link to the main body and/or a connection of the at least one charging link to the hinged door is a slidable connection configured to slide on opening and closing of the hinged door and configured to couple to at least one drive spring for priming of the at least one drive spring on the opening of the hinged door and/or the closing of the hinged door. The at least one drive spring is configured on activation of the auto-injector to drive a plunger driver forward within the auto-injector to operate the syringe received within the auto-injector.

Auto-injector

A needle shield remover for removing a needle shield from a syringe. The needle shield remover comprises a receiving means to receive at least part of the needle shield, removing means to detach the needle shield from the syringe whilst it is present in the receiving means; and retaining means to temporarily retain the needle shield in the receiving means after removal of the syringe. Temporarily retaining the needle shield in the needle shield remover allows the needle shield remover to be reused. Additionally, by retaining the needle shield the needle shield remover prevents the needle shield from being lost or dropped on the floor when it is not retained within the needle shield.
