Abstract: The liquid dispensing and receiving syringe includes an elongated preferably cylindrical transparent container open at its front and rear ends and defining a central cavity for holding liquid. A rearwardly extending plunger is slideably secured in the rear end of the cavity for dispensing liquid out the front end of the container and through a hollow needle or nozzle secured to the container front end and for sucking liquid into the cavity from the needle. A concentric protective shell is connected to and spaced outwardly from the container sidewall and is slideable between a first needle-expository position and a second needle-covering position. The shell has windows and/or a grid to permit viewing of the container. A number of spacer ears spaced on the container's outer surface and/or the shell's inner surface may temporarily or permanently lock in mating pockets and/or frictionally slide in longitudinal grooves in the container outer surface.
