ABSTRACT:
The present invention is directed to a syringe assembly (48), particularly useful for use with conventional prefilled pharmaceutical cartridge-needle units (46), including a hollow body (4) housing the cartridge-needle unit or other syringe structure. The substantially hollow body and the syringe structure include mating slits (28, 29, 30) and a ring (26) so that the needle (60) can be exposed for I.M. injection use and then withdrawn into the body for safety. The body is configured so that when the user diametrically squeezes the body adjacent the slit(s), the ring disengages the slit(s) due to the deformation of the body which permits the needle tip (62) to be positioned inside, for safety, or outside, for use, of the body. The internal position is also useful for safely injecting a pharmaceutical into an IV port (88). When the invention is used with a conventional pharmaceutical cartridge-needle unit as the syringe structure, the body can be part of an enclosure unit (2) which acts as the packaging for the pharmaceutical cartridge-needle unit, as the body of the syringe for administration of I.V. and I.M. injections, and as individual integral sharps containment for safe antineedle-stick disposal of the used cartridge-needle unit.
