Appl. No.:

12/420176

Inventors:

Youzhi Li - Longmont CO, US
Edward McKenna - Boulder CO, US
Andy Lin - Boulder CO, US
Sarah Hayman - Boulder CO, US

Assignee:

Nellcor Puritan Bennett LLC - Boulder CO

International Classification:

A61B 5/00

US Classification:

600424, 12820026, 12820714

Abstract:

According to various embodiments, a tracheal tube may employ optical sensing techniques for determining a distance between the inserted tube and an anatomical structure, such as a carina. The distance information may provide an indication as to whether or not the tracheal tube is properly placed within the trachea. The optical techniques may include backscattered intensity measurements.

Edward M. McKenna - Boulder CO, US

Assignee:

Covidien LP - Mansfield MA

International Classification:

A61B 5/00
A61B 6/00

US Classification:

600323, 600476

Abstract:

Multi-wavelength photon density wave (PDW) medical systems, methods, and devices are provided. In one embodiment, a multi-wavelength system may include a sensor, a sensor cable, and a patient monitor. The sensor may have an emitter and a detector configured to pass a multi-wavelength PDW input signal into a patient and receive a resulting multi-wavelength PDW output signal. The sensor cable may couple to the sensor and include two optical cables for transmitting and receiving the multi-wavelength PDW signals. The patient monitor may couple to the sensor cable and generate several single-wavelength PDW input signals by modulating a plurality of light sources. The monitor may include an optical switch configured to time-division multiplex the several single-wavelength PDW wave input signals by selecting one of the single-wavelength PDW signals at one time to produce a multi-wavelength PDW signal which is output from the monitor to the sensor via the sensor cable.

Assignee:

Covidien LP - Mansfield MA

International Classification:

A61B 5/1455

US Classification:

600310, 600476

Abstract:

Present embodiments are directed to a monitor system, such as a pulse oximetry system. The system may include a detection feature, an emission feature capable of emitting light into tissue and arranged relative to the detection feature such that the detection feature is capable of detecting the light from the tissue after passing generally through a portion of the tissue, a modulator capable of modulating the light to generate photon density waves at a modulation frequency generally in a range of 50 MHz to 3 GHz, a detector communicatively coupled with the detection feature, wherein the detector is capable of detecting characteristics of the photon density waves comprising amplitude changes and phase shifts, and a processor capable of making determinations relating to a value of a physiologic parameter of the tissue based at least in part on the detected characteristics.
