ABSTRACT:
An implantable fluid delivery device for dispensing metered amounts of liquid medication when a pump assembly within its casing is operated by finger pressure applied to a central target zone of the casing's top wall. The top wall also includes an injection site spaced from the central target zone for use when a bolus of medicament is to be injected into the device and delivered directly to the patient without passing through the pump assembly. The flattened pear shape of the casing and the location of the sites for pump activation and refilling on one hand, and for bolus injection on the other, facilitate errorfree use and operation of the device. Although limited fluid backup may occur during bolus injection, a valve arrangement within the device prevents intermixing of the bolus medicament with the liquid medication in the reservoir. In a second embodiment, a supporting grid prevents possible injury to the backup-restraining valve during bolus injection.
