Two way accumulatorprogrammable valve pump |
摘要 |
An improved implantable valve accumulator pump for the delivery of medication is disclosed. The implantable pump comprises a pressurized drug reservoir. The medication metering assembly comprises a fixed volume accumulator positioned between a pair of valves. The valves alternately open and close to admit medication from the reservoir into the accumulator and to dispense a precise volume pulse to an outlet catheter. In order to improve the pump's accuracy and to increase pumping volume while optimizing the pump's overall size and energy usage a two way diaphragm accumulator is used. The unit can be externally programmed or can be used in a fixed rate configuration that is never programmed but set at the factory or in the current programmable configuration.
