US Patent:

59658878, Oct 12, 1999

Filed:

Aug 12, 1997

Appl. No.:

8/909543

Inventors:

Craig A. Patton - Boulder CO

Assignee:

Datex-Ohmeda, Inc. - Tewksbury MA

International Classification:

G01N 2135

US Classification:

25033909

Abstract:

A gas spectrometer is provided for the monitoring of the maintenance of desired calibration conditions. The inventive method and apparatus is particularly apt for use in respiratory gas spectrometers. Monitoring may be achieved by first establishing calibration condition values obtained by passing radiation beams through a reference gas chamber and purged, sample gas chambers upon initial calibration. Subsequently, e. g. after the spectrometer has been utilized in the field, corresponding test condition values are obtained by passing radiation beams through the same reference gas chamber and purged, sample gas chambers. Comparisons utilizing the calibrated condition values and test condition values can be made to monitor calibration variances (e. g. variances, in optical pathway conditions and depletion of the radiation source(s) utilized in the gas spectrometer).

International Classification:

G01J 2135

US Classification:

250343

Abstract:

The disclosed gas analyzer (10) provides two separate folded optical paths (16 and 18) from a single source (12) to a single detector array (14) via a polychromatic filter (26). One optical path (16) passes through a sample gas chamber (24) containing a gas to be analyzed and the other path (18) passes through a reference chamber (30) containing a reference gas. On each optical path (16 or 18), radiation from the source (12) is collected by upstream optics (22 or 28) to form a converging beam (16b, c or 18b, c), thereby reducing or eliminating the need for collection optics at the detector array (14).

Abstract:

An endoscope system is provided with a graphical orientation indicator. An endoscope includes a flexible tubular body with a steerable distal end having a camera. A controller for the endoscope presents a user interface that displays a view from the camera and a graphical orientation indicator visually representing an orientation of the distal end of the endoscope.

Abstract:

A laryngoscope system includes a monitor having communication circuitry and that communicates physiological parameter information to communication circuitry of a paired laryngoscope. The paired laryngoscope includes a camera and a display configured to display image data from the camera. A processor of the laryngoscope is programmed to generate instructions to provide a physiological parameter indicator via the laryngoscope based on the received physiological parameter information from the monitor.

Abstract:

A steerable endoscope is provided with active steering control. An endoscope includes a flexible tubular body with first and second articulating segments, and a camera. In an embodiment, the endoscope includes an orientation sensor. A controller for the endoscope performs an automated analysis of an alignment between the motion axis of the endoscope and the viewing axis of the camera, and actively steers the endoscope to improve the alignment.

Abstract:

A multifunctional laryngoscope is provided that includes a handle comprising a proximal end and a distal end and a display screen on the handle. The laryngoscope includes a laryngoscope camera at the distal end of the handle and connects to an introducer comprising an orientation sensor at a distal end of the introducer. The laryngoscope includes a processor programmed to execute instructions for receiving from a steering input a steering command in a first reference frame, and mapping the steering command to a second reference frame oriented to the distal end of the introducer based on an orientation signal from the orientation sensor.
