Abstract: A protective device (2) for a conventional catheter assembly (4) of the type used by blood banks and including a needle mount (12), a forwardly extending needle (10), and a rearwardly extending conduit (14), the protective device comprising: a sleeve member (6) adapted to be slidably supported on the conduit in a first non-shielding position, and adapted to be forwardly displaced relative to the catheter assembly from the first non-shielding position to a second non-shielding position wherein the sleeve member is restrained relative to the catheter assembly, and adapted to be forwardly displaced relative to the catheter assembly from the second non-shielding position to a shielding position wherein the needle is shielded.

Abstract: A protection assembly (22) for a wing catheter (10) is described, the protection assembly having: a sleeve member (24) adapted to be longitudinally displaced relative to the wing catheter from a needle exposed position to a needle protected position; and fixing means for fixing the sleeve member in the needle protected position, wherein the sleeve member comprises a pair of submembers (26, 28) adapted to be locked together to form the sleeve member, the sub-members defining open-ended slots therebetween for receiving the wing (18, 20) of the wing catheter.

Abstract: A scalpel that has a blade member; a handle adapted to receive a mandrel therein and having an opening; and a mandrel closely received within the handle. The mandrel can support the blade member and includes engagement structure for operative engagement by a user for movement of the mandrel within the handle. Biasing structure is provided for biasing the mandrel from an operative location adjacent the opening to an inoperative location within the handle, and restraining structure is provided for restraining the mandrel in the operative position against the action of the biasing means.
