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.

Publication number: 20100222737Abstract: A high flow rate infusion unit includes a heating unit with opposing, electrically-operated heating plates that contact a heat exchanger to heat infusate flowing therethrough. Pressure infusers on the infusion unit are operable to provide infusate at a high flow rate. A flat, elongate heat exchanger has a laminar fluid flow path receivable between the heating plates to which heat is conducted by contact with the heating plates. A bubble trap and a valve are disposed within the heat exchanger. The bubble trap collects bubbles and vents air from infusate exiting the fluid flow path, and the valve shuts off the flow of infusate if the volume of air in the bubble trap exceeds a predefined limit.Type: ApplicationFiled: April 16, 2010Publication date: September 2, 2010Applicant: Arizant Healthcare Inc.Inventors: Randall C.

Publication number: 20100161016Abstract: A patient warming blanket includes a pouch and a flexible heating assembly. The flexible heating assembly is enclosed within the pouch and includes, at least in part, a flexible sheet-like heater and a temperature sensor assembly attached to the heater in proximity to a surface thereof; a visible marker is located on an exterior of the pouch to identify a location of the temperature sensor. A method for covering a patient with the patient warming blanket, in order to effectively warm the patient, includes viewing the marker so as to position an area of the blanket, which corresponds to the sensor location, for direct contact with the patient, when the blanket is placed over the patient.Type: ApplicationFiled: December 19, 2008Publication date: June 24, 2010Applicant: Augustine BioMedical and Design, LLCInventors: Scott D.
