Patent number: 6277144Abstract: The present invention relates to an improved thermal conditioning apparatus for thermally treating a patient. More specifically, the present invention relates to an inflatable apparatus for bathing a patient with a thermally conditioned medium. Such a treatment apparatus is useful for medically treating a patient suffering from hypothermia or hyperthermia, or for maintaining the body temperature of a patient undergoing a surgical procedure. A thermal conditioning apparatus according to the present invention includes first and second pluralities of orifices, the first plurality of orifices being smaller than the second plurality. An inlet portion which receives the thermal conditioning medium is located closer to the first plurality of orifices than the second plurality of orifices. The combined use of smaller orifices in close proximity to the inlet portion with larger orifices distal from the inlet portion tends to minimize the thermal gradients that may occur.Type: GrantFiled: October 7, 1998Date of Patent: August 21, 2001Assignee: Respiratory Support Products, Inc.Inventors: Kerry Tomic-Edgar, Gordon Shigezawa, Anthony V.

Patent number: 5357954Abstract: A blood oxygen saturation sensor or oximeter is mounted to a probe for insertion into the esophagus of a patient. The sensor includes a set of optical transmission elements and an optical detector for optically detecting the blood oxygen saturation of tissues of the esophagus. By mounting the blood oxygen saturation sensor to a probe for insertion into the esophagus, blood oxygen saturation measurements are obtainable at a physiologically stable site which is fully isolated from ambient light external to the patient. The probe for insertion into the esophagus may additionally be provided with a heart and respiration sound sensor and a temperature sensor. With such a combination, a single probe provides the detection of several useful physiological parameters, including temperature, heart, and respiration sounds and blood oxygen saturation levels. The esophageal probe is reliably and inexpensively constructed of few components and is ideally suited for one-time use.Type: GrantFiled: January 4, 1993Date of Patent: October 25, 1994Assignee: Respiratory Support Products, Inc.Inventors: Gordon Shigezawa, Anthony V.

Patent number: 5161892Abstract: Temperature measurement with thermocouples is made more accurate, and the cost of disposable thermocouples is reduced by locating the cold junction close to the hot junction, utilizing a thermistor in thermal communication with the cold junction in developing a compensating voltage which varies with temperature as does the voltage produced by the cold junction, and applying the compensating voltage to cancel the cold junction voltage. The presence of radio frequency fields in the region of the thermocouple is detected and utilization of the thermocouple voltage is interrupted in intervals when the interference is greater than some preselected intensity. Further, the thermocouple voltage information is utilized to simulate the resistance a thermistor would have at the temperature represented by the thermistor voltage information and that simulated resistance is applied to instrumentation designed to measure temperature with a thermistor.Type: GrantFiled: August 30, 1991Date of Patent: November 10, 1992Assignee: Respiratory Support Products, Inc.Inventors: Gordon Y.

Patent number: 5088835Abstract: A reusable cable apparatus for interfacing disposable temperature probes with a patient monitor. One reusable cable connects a thermocouple probe to the patient monitor and has a phone plug connection wherein a cold junction and cold junction compensation is located. A second reusable cable connects a thermistor probe to the patient monitor through a similar phone plug. Circuit means in the patient monitor receives either phone plug and produces an output signal which is substantially the same regardless of whether the thermocouple and first reusable cable or thermistor and second reusable cable are connected. The effect of secondary thermocouple junctions in interconnecting connector shells is substantially eliminated by connecting lead wires to contact pins such that the secondary junctions are physically close to one another.Type: GrantFiled: December 31, 1990Date of Patent: February 18, 1992Inventors: Gordon Shigezawa, Anthony V.
