An inexpensive add-on device to help prevent any user of hypodermic syringes from having an accidental ''stick'' from an exposed needle. Two round discs (1, 4), with a connecting strap (3), are formed from a sheet of soft plastic. The first mounting disc (4), with a suitable yielding aperture (5), is pressed on to the syringe cylinder (6) up to the hilt; and a second shielding disc (1) is pressed on to the needle cover (8), up to its hilt, before the hypodermic needle (10) has been uncapped or issued to the user. When the needle (10) is uncapped for use, the cap is retained by th connecting strap (3), so it cannot be lost or forgotten. When the needle is recapped for disposal, the limited length of the connecting strap (3) prevents the needle from being approached head-on; and the second disc (1) shields the holding finger tips. |
