Medical pump with lockout system
First Claim
1. A pumping apparatus for administering fluids to a patient, the pumping apparatus comprising:
- a pump for controlling the flow of fluid to the patient;
a controller for controlling the operation of the pump;
a user interface operatively connected to the controller comprising a plurality of push buttons for providing inputs to the controller when said push buttons are depressed in an unlock state of the pump, at least some of the inputs being capable of causing the controller to change operation of the pump;
at least one of said plurality of push buttons having multiple functionality, said one push button being operable when depressed and released in the unlock state of the pump to provide an input for use in affecting the operation of the controller, said one push button being operable when depressed and held in a depressed position for a predetermined time interval in the unlock state of the pump to initiate a lockout state of the pump in which the push buttons including said one push button are disabled from providing inputs to the controller.

Abstract
A pumping apparatus for administering fluids to a patient. The pump apparatus includes a pump, a controller, and a user interface operatively connected to the controller having a plurality of push buttons for providing inputs to the controller when the push buttons are depressed in an unlock state of the pump. At least some of the inputs are capable of causing the controller to change operation of the pump. At least one of the plurality of push buttons has multiple functionality and is operable when depressed and released in the unlock state of the pump to provide an input for use in affecting the operation of the controller. The one push button is operable when depressed and held in a depressed position for a predetermined time interval in the unlock state of the pump to initiate a lockout state of the pump.

13. A method of controlling a pumping apparatus comprising a pump for controlling the flow of fluid to the patient, a controller for controlling the operation of the pump, and a user interface operatively connected to the controller comprising a plurality of push buttons for providing an input to the controller when said push buttons are depressed in an unlock state of the pump, the method comprising:
-
depressing and releasing at least one of said plurality of push buttons in an unlock state of the pump to provide an input to the controller for use in affecting operation of the controller;
depressing and holding said one depressed push button in a depressed position in the unlock state of the pump for a predetermined time interval;
initiating a lockout state upon detection of said one push button being held in the depressed position for said time interval in which the push buttons including said one push button are disabled from providing inputs to the controller thereby preventing unintended adjustment to operation of the pump. - View Dependent Claims (14, 15, 16, 17)
