Publication number: 20100256715Abstract: A forced air warming unit has a casing with inlet and outlet openings. The casing encloses a scroll housing with a curved inside surface in which a blower is disposed. A circuit board in the casing encloses the blower in the scroll housing. At least one opening penetrates the circuit board. A heater plate is disposed between the circuit board and the blower. The blower draws air through the inlet opening, along a first side of the circuit board through the at least one opening into the scroll housing. The blower also forces air along a second side of the circuit board which faces the scroll housing, through air passages in the circuit board, along the first side through the at least one opening, into the scroll housing. The blower accelerates air along the curved inside surface and past the heater plate. Heated, pressurized air exits through the outlet opening.Type: ApplicationFiled: June 11, 2010Publication date: October 7, 2010Applicant: Arizant Healthcare Inc.Inventors: Gary L.

Patent number: 7338515Abstract: In a convective system that includes a blower to thermally treat and pressurize air, a convective device to receive and convect the thermally-treated pressurized air, and an air hose to conduct a flow of thermally-treated pressurized air from the blower to an inlet port in the convective device, an interface device is provided to control the flow of air at the interface where the inlet port and an end of the air hose operate to conduct the flow of air out of the air hose into the convective device. The interface device is received at the end of the air hose and operates to support the flow of air out of the end when the end and the inlet port are brought together. The interface device operates to stop, inhibit, or restrict the flow of air out of the end when the end and the inlet port are separated.Type: GrantFiled: April 23, 2002Date of Patent: March 4, 2008Assignee: Arizant Healthcare Inc.Inventors: Albert Philip Van Duren, Allen Hamid Ziaimehr, John Paul Rock, Scott Douglas Augustine, Gary Rabindranath Maharaj, Randall Charles Arnold

Patent number: 7220273Abstract: Airflow provided through an air hose to the inlet port of an inflatable thermal device is controlled by a mechanical device disposed at an end of the air hose that is coupled to the inlet port. In response to coupling the end of the air hose to the inlet port, the mechanical device operates to open the end and permit air to flow through the air hose and the inlet port. In response to decoupling the end of the air hose from the inlet port, the mechanical device operates to block air from flowing through the end of the air hose.Type: GrantFiled: December 17, 2001Date of Patent: May 22, 2007Assignee: Arizant Healthcare Inc.,Inventors: Albert Philip Van Duren, Allen Hamid Ziaimehr, John Paul Rock, Scott Douglas Augustine, Gary Rabindranath Maharaj

Patent number: 6876884Abstract: A forced air warming unit has a casing that encloses a scroll housing with a curved inside surface. A blower is disposed in the scroll housing inside the curved surface. Inlet and outlet openings are provided in the casing. A circuit board is mounted in the casing, against the scroll housing so that the blower is enclosed in space between the scroll housing and the circuit board. At least one opening is provided through the circuit board into the space in which the blower is disposed. A tapered, elongate, arcuate heater plate is disposed in the scroll housing between the circuit board and the blower, with a relatively wide end near the outlet opening and a second, relatively narrower end near the curved inside surface. Air is conducted in response to operation of the blower through the inlet opening, along a first side of the circuit board through the one or more openings in the circuit board into the scroll housing.Type: GrantFiled: April 10, 2003Date of Patent: April 5, 2005Assignee: Arizant Healthcare Inc.Inventors: Gary L.

Patent number: 6775473Abstract: An intravenous (IV) fluid warming system with a removable heat exchanger includes a presence detector. The system is for warming an IV fluid before infusion into a body. The system includes a warming unit for warming the IV fluid and an inlet slot for receiving a heat exchanger, preferably embodied as a cassette. The heat exchanger is sized to fit into the inlet slot of the warming unit. The heat exchanger has a heat exchanger membrane with an internal fluid pathway that is in fluid communication with a fluid inlet port and a fluid outlet port. While the heat exchanger is in the warming unit, the IV fluid flows through the internal fluid pathway of the heat exchanger, warming the fluid. A heat exchanger presence detector is part of the warming system. The presence detector detects the presence of the heat exchanger when it is received in the warming unit. The presence detector enables the heating operation of the warming unit when the presence of the heat exchanger is sensed.Type: GrantFiled: November 25, 2002Date of Patent: August 10, 2004Assignee: Arizant Healthcare Inc.Inventors: Scott Douglas Augustine, Gary Rabindranath Maharaji, Allen Hamid Ziaimehr, Scott Allen Entenman

Patent number: 6541740Abstract: A substantially constant load impedance electrical heater has been provided. The heater is comprised of two sections, a first heater and a second heater. The first heater is continuously “on” to provide the bulk of the heat. A second heater is selectively engaged to provide slightly more heat to the medium, heating the medium to the desired temperature. The output temperature of the heated medium is maintained by controlling the duty cycle of the second heater. More drastic changes in temperature are accomplished by changing the power continuously dissipated by the first heater. The greatest heating control is obtained by defining the first and second heaters as subsets from a bank of selectable heater elements. A method of minimizing fluctuations in the loading of a high-wattage electrical device is also provided.Type: GrantFiled: October 3, 2001Date of Patent: April 1, 2003Assignee: Augustine Medical, Inc.Inventors: Allen Hamid Ziaimehr, Albert Philip Van Duren, Peter Donald Fraley

Patent number: 6447538Abstract: A condition is detected between an inlet port of an inflatable thermal device, such as an inflatable thermal blanket, and an end of an air hose through which a flow of pressurized, thermally treated air is provided to the device by way of the inlet port. The condition may be disconnection of the end of the air hose from the inlet port or the identification of a particular style of inflatable thermal device. A response to the condition may include provision of a perceptible indication that the condition has occurred. Other responses may include cessation of the flow of air or changing an air flow characteristic.Type: GrantFiled: April 10, 2000Date of Patent: September 10, 2002Assignee: Augustine Medical, Inc.Inventors: Albert Philip Van Duren, Allen Hamid Ziaimehr, John Paul Rock, Scott Douglas Augustine, Gary Rabindranath Maharaj
