ABSTRACT:
A bulb syringe providing for uniform, hence repeatable, deflation/inflation of the bulb and a tactile-discernible limit of deflation of the bulb and resultant control over the consistency of degree of suction produced with the deflated bulb is allowed to inflate in response to its resiliency and memory. The bulb syringe includes a bottom portion having a spout and a top portion whose resiliency is enhanced by a plurality of ribs. The top and bottom portions are provided with equatorial shoulders which are joined and which establish a tactile-discernible limit of deflation of the top portion. In one embodiment, the bottom portion is provided with a pair of lugs on the outer surface therefor for receipt of the palmar surfaces of two adjacent fingers of a user. Preferably, the syringe is transparent or at least sufficiently translucent as permits the visual inspection of any fluid contained therein.
