<p>A medical sharp protection device for minimising the risk of accidental injury by medically sharp instruments such as a hypodermic needle. The device consists of a sheath (6) covered by an elastomeric material (10) which covers the needle (2). The sheath (6) can only be retracted over the needle (2) exposing the sharp end of the needle (3) when the sheath (6) and the needle shaft (2) are lined up in one relative angular position, which is not the normal rest state. To achieve this the sheath has to be rotated and the elastic and longitudinal force of the elastomeric material overcome. Since this is an active step the needle can only be exposed by two independent actions. When the elastomeric cover is released the sheath returns to its state of rest in which the sheath connot be exposed without applying a rotation force. The needle sharp end is thus covered preventing personal injury.</p> |
