NEEDLESTICK PREVENTION DEVICE

摘要

A needlestick prevention device for an injection device having a hollow needle (3) comprises a sheath (1) for attachment to the injection device. The sheath (1) has three positions. In a first, inoperative position the sheath (1) sealingly encloses the needle (3). In a second operative position a first part (4) of the sheath (1) is removed, a second part (5) remains attached to the injection device and a third part (6) is pivoted about a hinge (16) to expose the needle. In a third, cover position the third part (6) is pivoted about the hinge (16) to cover at least the tip of the needle (3) and is retained in position by retaining means (19) acting between the second part (5) and the third part (6). The device is simple to manufacture and use.
