Abstract: An apparatus (10) for the repetitive dispensing of a predetermined quantity of eyedrops (12) has a cylinder (14) with a restricted opening (18) at a first end (16). A plunger (20) attached to rod (23) extends into the cylinder (14) from end (22). Biasing member (28) has a ramped cam surface (32) incorporating a pair of steps (46), actuating member (26) has an opposed surface (30) with a projection (44) which rides on ramped cam surface (32) and drops off step (46) when actuating member (26) is rotated. Rotation of the actuating member (26) also advances the actuating member (26) on threaded member (24). Spring (42) biases surfaces (30) and (32) together. A projection (44) drops over each step (46), plunger (20) is moved incrementally toward end (16) of cylinder (14) to discharge eyedrops (12) through opening (18 ). A disposable cartridge (50) may be substituted for the cylinder (14).
Abstract: An improved drop dispenser for use with a closed compressible container, which dispenser is comprised of a small diameter tubular dispenser member of a resilient plastic material deformed at the free end thereof to provide a normally closed, integral valve-like arrangement, which valve-like arrangement is pressure actuated and partially opens when pressure within the container increases.
Abstract: The disclosure is of eye irrigating apparatus comprising a scissors mechanism having two blades, between which a tubular body is positioned, through which an irrigating fluid can flow into the eye from a fluid source.
