First Claim
1. An accessory for converting a programmable infusion pump to a patient-controlled analgesia device, comprising:
- (a) a converter shaped to fit on said pump, said converter having a cover portion movable between an open position in which said converter is releasable from said pump and a closed position in which said converter can be secured to said pump;
(b) lockout switch means on said converter for preventing modification of the program of said infusion pump when said cover portion is closed, said lockout switch means being inaccessible when said cover portion is closed;
(c) dosing switch means attached to said converter for triggering operation of said pump under patient control, said dosing switch means being accessible when said cover portion is closed;
(d) connector means on said converter for electrically connecting said switch means to said pump;
(e) connector latching means for releasably holding said connector means in engagement with said pump, said latching means being inoperable to release said connector means when said cover portion is closed; and

Abstract
A removable cover for converting a programmable infusion pump into a patient-controlled analgesia (PCA) device. The cover can be placed onto an infusion pump and electrically connected thereto when open. The cover includes an internal switch which allows selection of normal or PCA pump operation. A second internal switch automatically disables the keyboard of the pump when the cover is closed. The cover is lockable, and when it is closed and locked, the internal switches are inaccessible, the cover cannot be removed from the pump, and the electrical connection to the pump cannot be disconnected. When closed, the cover also defines an inaccessible compartment for the storage of medication. An external push button is provided to allow the patient to trigger analgesia doses at safe intervals when the pump is in the PCA mode.
