Abstract

Implantable flow regulator for the infusion of drugs in a human or animal body from a pressure-activated drug dispensing apparatus such as an implantable infusion pump. The flow regulator is designed to compensate for fluctuations in the ambient pressure and temperature in order to ensure an accurate, homogeneous quantity of the drug flow. The flow regulator comprises a body 10 with a shallow cavity, which is divided into two chambers 18, 19 by a flexible membrane 15. The first of the said chambers 18 is a pressure-registering chamber. The second is a valve chamber 19, through which the drug flows, the outlet 21 from the first chamber being located centrally below the membrane, and flexing of the membrane in one direction as a result of increased pressure in the second chamber producing contact with an elastomer sealing ring 28 around the outlet and closing the flow path. At least one capillary restrictor 33 is fitted in the flow line between the drug dispensing apparatus and the flow regulator. The pressure drop in this restrictor controls the operation of the flow regulator valve. <IMAGE>
