Disposable Anti-Fog Airway Adapter

View page
US Patent:
6095986, Aug 1, 2000
Filed:
Jul 28, 1998
Appl. No.:
9/123232
Inventors:
James R. Braig - Piedmont CA
Daniel S. Goldberger - Boulder CA
Roger O. Herrera - Engeryville CA
Mark L. Yelderman - Dallas TX
Assignee:
Square One Technology, Inc. - Boulder CO
International Classification:
A61B 508
US Classification:
600532
Abstract:
A disposable anti-fog airway adapter for use with a mainstream respiratory gas analyzer which provides a measurement of a patient's inhaled and exhaled gases. The airway adapter includes windows that are constructed of a thin, low heat capacity plastic that rapidly equilibrates to the temperature of the warm moist gases in the patient breathing circuit. In addition, the inside of the windows is also coated with an anti-fog surfactant either by laminating an anti-fog film with the window plastic prior to attaching the window to the airway adapter body or by first attaching the window to the airway adapter body and then applying the surfactant to the airway adapter after the window film is bonded in place so that the surfactant coats the entire inside of the adapter. The surfactant functions to increase the critical wetting tension of the surface it covers so that water on the window spreads into a uniform thin layer which does not absorb very much infrared energy and thus does not significantly reduce the signal strength. "Instant on" operation is accomplished because no heater and the like is necessary to warm up the windows to maintain them at an elevated temperature to prevent fogging.

Shutterless Mainstream Discriminating Anesthetic Agent Analyzer

View page
US Patent:
52967069, Mar 22, 1994
Filed:
Dec 2, 1992
Appl. No.:
7/985793
Inventors:
James R. Braig - Oakland CA
Daniel S. Goldberger - Boulder CO
Mark L. Yelderman - Plano TX
Roger O. Herrera - Oakland CA
Assignee:
Critikon, Inc. - Tampa FL
International Classification:
G01J 52
US Classification:
250339
Abstract:
An anesthetic agent analyzer having six or more independent analytical channels, where each channel comprises a first thermopile which receives incident infrared radiation and a second thermopile behind the first thermopile which is blocked from the incident infrared radiation and thus serves as a reference for detecting ambient temperature variations. The first and second thermopiles are connected in a "parallel opposed" fashion so that the effects of ambient temperature variations automatically cancel and the detectors may be readily configured in a detector package. The anesthetic agent analyzer of the invention is designed for use with a wideband infrared radiation source so that anesthetic agents having characteristic absorption bands in the far infrared wavelength range (6-15 microns) may be more readily detected and discriminated. When implemented in a mainstream configuration, a disposable airway adapter with windows formed of polypropylene or some other suitable window material which minimally attenuates the infrared energy at the wavelengths of interest is also used. The concentrations of the discriminated anesthetic agent gases are then calculated using a second order polynomial equation having cross product terms.

Sensor Having Cutaneous Conformance

View page
US Patent:
48300144, May 16, 1989
Filed:
Jul 7, 1987
Appl. No.:
7/070619
Inventors:
David E. Goodman - San Francisco CA
James E. Corenman - Menlo Park CA
William New - Woodside CA
Mark Yelderman - Menlo Park CA
Assignee:
Nellcor Incorporated - Hayward CA
International Classification:
A61B 502
US Classification:
128665
Abstract:
A sensor for trans-illumination of a blood perfused portion of flesh to measure light extinction during trans-illumination is disclosed. The sensor is preferably mounted on a fingertip but any digit or blood perfused portion of flesh will work. The sensor includes a first end for disposition on one side of the trans-illuminated flesh and a second end for disposition on the opposite and opposed side of the trans-illuminated flesh. A light source is mounted to the first side and a photo-sensor is mounted to the second side. If an elongated flexible strip is used, it is provided with adhesive and is suitably windowed that light is allowed to take an optical path through the finger. If no flexible strip is used, the two ends are aligned and secured to the flesh such that the light emitted takes an optical path through the finger. When the adhesive fastener is used, the effect of the light source and photo-detector substrates being integrated into the adhesive fastener is that they become, in effect, a part of the skin. The resulting device is resistant to accidental removal and avoids constriction of blood vessels.

Method And Apparatus For Measuring Flow

View page
US Patent:
45079749, Apr 2, 1985
Filed:
Apr 21, 1983
Appl. No.:
6/487334
Inventors:
Mark L. Yelderman - Menlo Park CA
Assignee:
The Board of Trustees of the Leland Stanford Jr. University - Stanford CA
International Classification:
G01F 170
G01F 168
US Classification:
7386106
Abstract:
Flow, and in particular nonuniform flow, as in a vascular system, is measured by applying a stochastic excitation signal to a system inlet which results in a measurable output signal at a downstream system outlet. Flow rate may be extracted by cross-correlating the excitation signal and the output signal. Calibration may be effected by conservation of mass principles whereby quantity type parameters are related to concentration type parameters. The stochastic signal has the characteristics of white noise, such that simplified spread spectral detection and signal extraction techniques may be employed to recover the desired intelligence.
