Embodiment Construction

[0013] Referring now to the drawings, an enteral delivery pump (generally, a "pumping device") constructed in accordance with the principles of the present invention is generally designated 1 . The delivery pump 1 comprises a housing, generally designated 3, configured to accommodate a drug delivery device generally designated 5 (generally, "pump device"). A partial portion of the delivery device is shown in FIG. 3 . A suitable pump arrangement is shown in commonly assigned US Patent Application No. 10 / 853,958, filed May 24, 2004, entitled "Flow Control Apparatus," the disclosure of which is incorporated herein by reference. The housing 3 includes a door 7 hinged to the remainder of the housing for pivoting between a closed position ( FIG. 1 ) and an open position ( FIG. 3 ) that exposes a portion of the pump that receives the drug delivery device 5 . The pump 1 has a user interface, generally designated 13, comprising a display screen 15 on the front of the housing 3 and a p...

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.

Description

technical field [0001] The present invention relates generally to pumps for delivering fluid to a patient via a drug delivery device, and more particularly to such a pump having a user interface for activating a locked state of the pump. Background technique [0002] The administration of fluids containing drugs or nutrients to patients is well known in the art. Typically, fluid is delivered to the patient by a pump device, such as a peristaltic pump, mounted on a flow control device, which delivers fluid to the patient at a controlled delivery rate. Peristaltic pumps typically include a housing including a rotor or the like operatively engaged with at least one motor through a gearbox. The rotor drives fluid through the conduits of the pump device by a peristaltic action caused by the rotation of the rotor via the motor. The motor is operatively connected to a rotatable shaft that drives the rotor, which in turn progressively compresses the conduit and drives fluid to flo...
