Abstract: A liquid dispenser for medical applications includes a pressurized liquid container, a nozzle, and a conduit or flow guide connected to the container and the nozzle for defining a flow path between the container and the nozzle. A manually actuatable flow rate control mechanism is operatively coupled to the conduit or flow guide and is manipulable by a user to adjust an average rate of flow of liquid from the container to the nozzle. In addition, a manually actuatable pulse rate control mechanism is operatively coupled to the conduit or flow guide and is manipulable by a user to adjust a rate of pulsation in liquid flowing from the container to the nozzle. The invention thus enables a user to set flow rate and pulsation frequency as desired.

Abstract: A liquid dispenser assembly for medical applications includes a container holding a predetermined quantity of a therapeutic liquid in a storage chamber. The container has a wall or panel provided with a port. A dip tube is disposed in the chamber and extends from the port to a lower portion of the storage chamber. The disepnser assembly further includes a hollow compressible dispenser body. An applicator tube is attached at one end to the dispenser body and extends at a free end, i.e., an end opposite the dispenser body, into the dip tube. The applicator tube is removable from the dip tube after an expansion of the dispenser body from a collapsed configuration and a concomitant drawing of an aliquot of the liquid into the dispenser body through the dip tube and the applicator tube.
