Patent number: 8172798Abstract: A system for managing an infusion therapy, including: a server in communication with a central server; and an infusion pump in wireless communication with the server and for: uploading respective label data from respective labels for at least one medication, the respective label data including respective label pump programming data for infusion of the at least one medication by the pump; wirelessly transmitting the uploaded label data to the server; and wirelessly transmitting pump data identifying the pump to the server. The server is for transmitting the pump data and the respective label data to the server; and receiving, from the central server and in response to receipt of the pump data and the respective label data by the central server, second pump programming data regarding a second medication. The server is for comparing the first pump programming data with the second pump programming data.Type: GrantFiled: May 12, 2009Date of Patent: May 8, 2012Assignee: Sigma International General Medical Apparatus LLCInventors: Roger L. Hungerford, Tuan Bui, Gary Colister

Publication number: 20120095433Abstract: An infusion pump, including: a microprocessor; a drip chamber; a drip tube with an end in the drip chamber; and an illumination system: with a light source for transmitting light through the drip chamber to a drop of fluid suspended from the drip tube; and for controlling illumination properties of the light transmitted to the drop. The pump includes an optical system for: receiving light transmitted through the drop; and transmitting, to the microprocessor, data regarding the received light. The microprocessor: generates, using the data, an image of the drop; locates, using the image, an outer edge of the drop to define a boundary of the drop; integrates an area enclosed by the boundary; and calculates a volume of revolution for the drop with respect to an axis for the drop that intersects the end of the drip tube, assuming symmetry of the drop with respect to the axis.Type: ApplicationFiled: October 19, 2010Publication date: April 19, 2012Applicant: SIGMA INTERNATIONAL GENERAL MEDICAL APPARATUS LLCInventors: Roger L.

Publication number: 20100204650Abstract: An infusion pump including an interface unit for receiving first data for a first infusion regimen for a medication, the first regimen including a first unit of measure in which the first regimen is executed and after receipt of the first data, second data for a second infusion regimen for the medication, the second regimen including a second unit of measure in which the second regimen is executed. The pump also includes a processor for comparing the first and second units of measure. In one embodiment, the pump includes a graphical user interface, and the processor identifies a difference between the first and second units of measure; generates, using the processor, a warning message; and displays the message on the graphical user interface. In another embodiment, the processor holds in abeyance initiation of the second infusion regimen in response to identifying the difference between the units of measure.Type: ApplicationFiled: February 9, 2009Publication date: August 12, 2010Applicant: Sigma International General Medical Apparatus LLCInventors: Roger L. HUNGERFORD, Curt Matthew ALLEN

Patent number: 7059840Abstract: An apparatus for pumping fluid through tubing comprising a stop platen is disclosed. The stop platen is operatively arranged to depress a wall of the tubing along a section of a longitudinal axis of the tubing. The stop platen is narrower than the tubing along a transverse axis of the tubing. The invention further comprises a cabinet containing the stop platen, a door rotatably fixed to the cabinet, and locking means for preventing rotation of the door. The locking means are operatively arranged to be unlocked by a tubing occluder.Type: GrantFiled: April 5, 2002Date of Patent: June 13, 2006Assignee: SIGMA InternationalInventors: Kenneth J. Corwin, Roger L. Hungerford, Yuriy Shvetsov, Michael H. Wollowitz

Patent number: 5567120Abstract: A holder for an IV tube roller clamp is removably secured in the housing of an electronic infusion device, and has in opposite ends thereof a pair of photo-electric devices, one of which detects when the roller of the clamp is in its tube opening position, and the other detects when the roller is in tube closing position. A lever is pivotal on the housing between a closed position in which it operatively connects the IV tube to a pump unit in the housing, and an open position in which it permits removal of the IV tube from the unit. The spring-loaded armature of a solenoid prevents the lever from being opened until the solenoid coil is energized, and the photo-electric devices prevent the solenoid coil from being energized until the roller is in its tube closing position. When closed, the lever overlies part of the tube channel in which the IV tube is seated and also shifts a pressure plate in the pump unit to a position in which a lip thereon overlies another portion of said channel.Type: GrantFiled: October 13, 1994Date of Patent: October 22, 1996Assignee: Sigma InternationalInventors: Roger L.
