Abstract
Apparatus for feeding liquids, particularly medications such as insulin, or the like, to humans or animals comprising a supply reservoir for the liquid, a conveying arrangement connected to the supply reservoir and including a pressure generating device for feeding the liquid by pressure application from the supply reservoir to the body, and a controllable dosing arrangement for producing a desired rate of infusion. The pressure generating device includes an overpressure generator which constantly maintains the liquid present in the supply reservoir under overpressure as distinct from the pressure prevailing at the point of liquid discharge. The dosing arrangement comprises a pilot or switching valve for periodically releasing liquid from the supply reservoir to the body, the switching valve being switchable for the purpose of fine dosing by the discharge of preselectable constant volumes of liquid at periodic intervals predeterminable in accordance with the treatment program.
