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.

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.

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.

Abstract:

Multi-wavelength photon density wave medical systems, methods, and devices are provided. In one embodiment, a multi-wavelength photon density wave patient monitor includes multiple light sources, a driving circuit, a fiber coupler, a sensor cable connector, a wavelength demultiplexer, detectors, and data processing circuitry. The driving circuit may modulate the light sources to produce several single-wavelength input photon density wave signals, which the fiber coupler may join into a multi-wavelength input signal. The sensor cable connector may provide this multi-wavelength input signal to a sensor attached to the patient and receive a multi-wavelength output signal. The wavelength demultiplexer may separate the multi-wavelength output signal into single-wavelength output signals for detection by the detectors. Based on a comparison of one of the single-wavelength output signals to a corresponding one of the single-wavelength input signals, the data processing circuitry may determine a physiological parameter of the patient.

Abstract:

An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. These cuffs may include features that facilitate detection or visualization of the cuff, for example with ultrasound devices, to ensure proper placement of the cuff and the tube. Such surface features may include particular types of materials or shaped or protruding features that may be detected in the environment of the trachea.

Abstract:

A business platform can provide access to applications and provide for the integration of resources with other applications, including internal and external applications, services and systems. A portal framework included within the platform can render portals including graphical user interfaces for displaying and receiving content that can be used by various applications. A portal framework can provide an interface to various resources such that information received and displayed by the portal framework can be exchanged with internal and external resources using standards-based transport protocols, messaging systems, and document types. An integration framework can be invoked to exchange this information among applications and services. An integration framework can provide access to resources by integrating the resources with an application server. The portal framework and integration framework can be implemented on an application server which can support enterprise applications. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
