  • Patent number: 6419658
    Abstract: A needle-covering sleeve (14), slidably fitted on the syringe barrel (1), is held in its retracted rest position by means of retaining tongues (10), which hook it at its rear rim (13). At the end of the injection stroke of the plunger (2), a rear flange (8) of the stem (3) of the plunger (2) radially opens the retaining tongues (10) apart, which release thereby the needle-covering sleeve (14). Then, the latter is axially advanced by means of a spring (16), to an advanced safety position, in which it entirely covers the needle (5) and is fastened to a sleeve-clamping ring (18), which is provided at the fore end of the syringe barrel (1). To this purpose, the sleeve-clamping ring (18) has peripheral elastic retaining tongues (19) which interact with matching retaining teeth (20) on the inner part of needle-covering sleeve (14) and prevent any axial backward movement of the needle-covering sleeve (14).

  • Patent number: 6319234
    Abstract: The syringe is provided with a needle-covering sleeve (14), which is slidably fitted on the syringe barrel (1) and is held in its retracted rest position by means of retaining tongues (10), which hook its rear rim (13). At the end of the injection stroke of the plunger (2), a rear head (8) of the stem (3) of the plunger (2) radially opens the retaining tongues (10) apart, which release thereby the needle-covering sleeve (14). Then, the latter is axially advanced by a spring (16), until it entirely covers the needle (5). The needle-carrier (4, 104) has at least one lateral locking projection (28), slidably engaging in a longitudinal slot (18), which is formed in the needle-covering sleeve (14) and is delimited at its sides, at least in its progressively tapering rear end (118), by two convergent and elastically openable stop sticks (19) which allow the passage of the locking projection (28) between their free ends, but then point against it and fasten it to the needle-covering sleeve.
