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.

摘要： An injection device which is devised to be safer in use than many prior such devices comprises a generally cylindrical barrel section (4, 42) which is substantially closed at its first end but has an aperture (6, 43) in that end to allow an injection needle (9, 41) to pass through it, a needle support member (10, 40, 60) to slide within the barrel section and shaped to receive one end of a liquid container such as an ampoule (12, 52, 61) of anaesthetic, and a plunger (7, 45, 62) mounted at the other end of the barrel section for axial movement in said section. The plunger is adapted both to express liquid from the liquid container when the plunger is advanced within the barrel and also to interconnect with either the needle support member of the liquid container, whereby withdrawal of the plunger withdraws both the liquid container and also the needle and its support member into the barrel section for disposal.
