Abstract
Abstract An ambulatory programmable pump (10) for infusing fluid to a patient having a built in display of user instructions comprises a foldable casing (12) having pumping apparatus (36) mounted therein and including fluid container means (30) for storing fluid to be infused to a patient. A central processing unit (50) is carried in the casing and connected to the pumping means, which is controlled by a keyboard (18) having keys (26) mounted on the casing for controlling operation of the processor and pumping means. A folding display (20) is hingedly connected to the casing and is movable between an open position for displaying instructions and information to the user to allow operation of the device, and a closed position where the display is protected from view. Also included are status indicating lights (102,104,106) and an audible alarm (108). The display screen has large, easily readable lettering, and the central processing unit generates prompting stimulus on the display for providing the user with instructions and requesting information to be entered into the keyboard, including rate of infusion and rate of infusion and volume of fluid to be infused. Also included is a method for carrying out same.
