The present invention is a headgear for noninvasive ventilation interface made up of a nasal cannula including cannula tubing having a given outside diameter, and a headgear yoke with ends including tubing retainers. The yoke is adapted to extend transversely over a wearer's head. The tubing retainers are C-shaped projections having a given length and an inside diameter substantially equal to the tubing outside diameter. The present invention further includes a retainer mating element for each o...

A method and apparatus for monitoring glucose, ethyl alcohol and other blood constituents in a noninvasive manner. The measurements are made by monitoring infrared absorption of the desired blood constituent in the long infrared wavelength range where the blood constituent has a strong and distinguishable absorption spectrum. The long wavelength infrared energy is passed through a finger or other vascularized appendage and the measurement made. To prevent the high energy source from burning or c...

Noninvasive, remote methods and apparatus for detecting early phases of neuro diseases such as the non-tremor phase of Parkinson's disease, dyskinesia, dyslexia and neuroatrophy, etc., are disclosed. Five words spoken either directly into a microphone connected to a local analysis system or remotely, as by way of a telephone link to a system for analysis of time and frequency domains of speech characteristics are representative of the presence of disease. The method includes the steps of transdu...

An improved noninvasive, electrooptical sensor probe is suitable for removable adhesive attachment to the skin of a patient to measure light extinction during transillumination of the blood-perfused tissue beneath the skin. The probe has a flexible generally U-shaped, web-like support structure having spaced, opposed upper and lower inner surfaces. A light source such as an LED is mounted in the support structure and positioned to emit light from one of the inner surfaces. A photosensor is also ...

A system for determining the hematocrit transcutaneously and noninvasively. Disclosed are a finger clip assembly and an earlobe clip assembly, each including at least a pair of emitters and a photodiode in appropriate alignment to enable operation in either a transmissive mode or a reflectance mode. At least two, and preferably three, predetermined wavelengths of light are passed onto or through body tissues such as the finger, earlobe, or scalp, etc. and the extinction of each wavelength is det...

Methods and systems are provided for biometric sensing. An illumination subsystem provides light at discrete wavelengths to a skin site of an individual. A detection subsystem receives light scattered from the skin site. A computational unit is interfaced with the detection system. The computational unit has instructions for deriving a spatially distributed multispectral image from the received light at the discrete wavelengths. The computational unit also has instructions for comparing the deri...

Glucose concentration is noninvasively measured by measuring a plurality of absorption values using at least one emitter operating at a corresponding plurality of emission wavelengths through a common optical sample volume and deriving glucose concentration from the absorption measurement values.

The present invention is drawn to apparatus for transcutaneous photodynamic therapy ("PDT") of a target tissue or compositions in a mammalian subject, which includes a light source that is external to the subject and is selected from among one or a plurality of laser diodes; light emitting diodes; electroluminescent light source; incandescent light sources; cold cathode fluorescent light sources; organic polymer light sources; or inorganic light sources, where the light source is adapted to dire...

Methods and systems for noninvasive mastopexy through deep tissue tightening with ultrasound are provided. An exemplary method and system comprise a therapeutic ultrasound system configured for providing ultrasound treatment to a deep tissue region, such as a region comprising muscular fascia and ligaments. In accordance with various exemplary embodiments, a therapeutic ultrasound system can be configured to achieve depth from 1 mm to 4 cm with a conformal selective deposition of ultrasound ener...

Utilization of a contact device placed on the eye in order to detect physical and chemical parameters of the body as well as the non-invasive delivery of compounds according to these physical and chemical parameters, with signals being transmitted continuously as electromagnetic waves, radio waves, infrared and the like. One of the parameters to be detected includes non-invasive blood analysis utilizing chemical changes and chemical products that are found in the conjunctiva and in the tear film...
