Injection device

摘要

An injection device 110 is described having a housing 112 and a cap 130. The injection device 110 houses a syringe 114 having a needle which is sealed by a boot 118. The cap 130 is arranged so that the boot 118 can be connected to the cap 130 while exerting a minimal force on the syringe, but cannot be removed from the cap 130 without applying a significantly greater force to the syringe. The housing 112 and cap 130 are arranged so that upon removal of the cap 130 from the housing 112, the boot 118 is removed from the syringe 114.

1. A cap for an injection device, the cap comprising:
a first part having a first end for receiving an injection device and a second end, the first part defining a first axis and having grip means for gripping a boot of a syringe, wherein the grip means is movable by a force from a first position to a second position and the grip means is capable of springing back from the second position to the first position, the second position being further from the first axis than the first position; and a second part having retention means for retaining the grip means, the retention means arranged such that movement of the retention means from a third position to a fourth position prevents the grip means from moving from the first position to the second position.
