Safety device for hypodermic needle or the like.

摘要

A safety device for a hypodermic needle (5) or for similar instrument used in the clinical puncture of the skin comprises a sheath (6) adapted to be connected to the needle (5) or to a support (4) for the needle (5). The sheath is so connected in a first position (Figure 1A, 2A or 3A) which permits normal use of the needle (5) and can be placed, by movement relative to the needle (5) Figure 1 B or 3B) or by folding upon itself (Figure 2B, 2C) in a second position in which the needle (5) is encapsulated by the sheath (6). The sheath (6) is retained in that second position, for example by a projection (9) extending into a slot (10) or through an aperture.
