Medical irrigation pump and system
First Claim
1. A disposable pump mechanism connectible to an irrigation fluid source, the pump mechanism being for use with a non-disposable drive mechanism and comprising:
- a pumping mechanism configured to produce an irrigation fluid output particularly suited for a predetermined medical procedure;
a housing which is adapted to mate with the drive mechanism and does not depend on the predetermined medical procedure for which the pump mechanism is suited; and
identifying indicia unique to the predetermined medical procedure comprising a pattern of bumps, which identifying indicia can be sensed by the drive mechanism.

Abstract
A medical irrigation pump and pump system utilize a permanent non-sterile drive motor capable of operating disposable sterile single use pump units each of which is specifically designed for a particular medical procedure. The pump units have housings which are adapted to be interchangeable within the permanent controller system. Only the sterilized and disposable pump units come into contact with the fluid pathway during pumping. A pattern of bumps on each pump unit is unique for the medical procedure for which the pump unit was designed. The pattern of bumps engages switches on the controller, enabling the controller to identify what type of pump unit has been installed. After automatically identifying the type of pump unit and the intended medical procedure, the controller automatically selects a default motor speed that will provide an appropriate fluid pressure for that particular procedure. Buttons on a control panel also enable the user to manually adjust the pressure delivered by the pump. The orientation of the pump unit during the loading procedure allows easy purging of all air from the pump unit before the pump is started.

11. A disposable pump mechanism connectible to an irrigation fluid source, the pump mechanism being for use with a non-disposable drive mechanism and comprising:
-
a centrifugal pump having a rotating vane and a housing wherein both the rotating vane and the housing are sized to produce an irrigation fluid output particularly suited for a predetermined medical procedure; a cover plate attached to the pump housing which is adapted to mate with the drive mechanism and does not depend on the predetermined medical procedure for which the pump is suited; and a pattern of identifying bumps on the cover plate wherein the pattern is unique to the predetermined medical procedure, which bumps can be sensed by the drive mechanism. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
