Inventors:

Gregg Kirkpatrick - Fallbrook CA, US

Assignee:

CareFusion 303, Inc. - San Diego CA

International Classification:

A61M 1/00

US Classification:

604151

Abstract:

An intravenous (IV) pump is disclosed. The IV pump includes a housing, a permanent magnet, an electromagnet, and a switch configured to selectably energize or de-energize the electromagnet. The permanent magnet generates a magnetic field and the electromagnet, when energized, generates a magnetic field that approximately cancels the magnetic field of the permanent magnet.

Assignee:

CareFusion 303, Inc. - San Diego CA

International Classification:

A61M 5/142

US Classification:

604151

Abstract:

An intravenous (IV) pump system is disclosed. The IV pump includes a pumping segment and an IV pump. The pumping segment comprises a receptacle configured to hold a medical fluid and an alignment feature attached to the receptacle. The alignment feature comprises one of a magnetic or a magneto-sensitive material.

Appl. No.:

12/896758

Inventors:

Gregg Rodne Kirkpatrick - San Diego CA, US

Assignee:

CareFusion 303, Inc. - San Diego CA

International Classification:

A61M 5/142

US Classification:

604500, 604153

Abstract:

A fluid pump apparatus for pumping a fluid from a fluid source to a fluid output comprises a first portion, such as a durable portion, and a second portion, such as a disposable portion. The first portion includes a fluid chamber having a wall and an internal cavity, an input port and an output port. A membrane forms a portion of the wall. The first portion further includes a magneto-sensitive element coupled to the membrane. The second portion comprises an actuator configured to contactlessly induce a reciprocating movement of the membrane by application of a time-varying magnetic field to the magneto-sensitive element, thereby facilitating pumping of the fluid through the fluid chamber.
