Provided herein is technology relating to medical monitoring of physiologic parameters, and particularly, but not exclusively, relating to compositions, methods and systems for the measurement of venous and arterial oxygen saturation in the blood of blood-filled anatomical structures.

Compositions and methods for measurement of oxygen saturation in blood filled structures

The present invention provides an electroionic processing system having a high frequency alternating current (AC) power source for treating potable water, process water, wastewater, biosolids, sludge, primary effluent, secondary effluent, and other biochemical processing functions, including producing hydrogen peroxide and other useful chemicals. An electromagnetic field is generated and coupled to an electrolytic treatment apparatus by a direct coupling apparatus and method, a capacitive coupling apparatus and method, and an inductive coupling apparatus and method. The present invention further comprises a process controller and a plurality of analyzers for monitoring various treatment process variables to adjust and optimize the process as necessary.

Electroionic processing system

This invention relates to a method and apparatus for the disinfection of water and wastewater contaminated with bacteria and other microorganisms. The apparatus includes an electrolytic flow cell including electrodes forming a part of flow pipe or open channel through which water or wastewater passes. The electrodes are formed of iron, stainless steel, carbon or copper and connected to a power supply voltage in the range of 20 to 100 volts and establishing a current in the range of 1 to 6 amperes. Disinfection results from either metal ions impacting microbial cells or through the generation of hydrogen peroxide, hydroxyl radicals and hypochlorous acid. When the electrodes are copper, toxic metal contamination limits are established through proper design of the flow cell. An ultrasonic transducer is connected to the electrodes and enhances hydroxyl radical generation.

This invention is an improve non-invasive electro-optical sensor probe ( ) that is initially L shaped to provide a mechanical means for accurate positioning of the sensor for subsequent use in connection with a patient appendage. The sensor further includes a leveling pad for at least partially surrounding a protruding sensor element ( ) to minimize protrusion of the element into the skin of a patient, and a functional liner ( ) for use in pretest of the sensor prior to positioning on a patient.

Oximeter sensor with functional liner

A computer-based instrument to produce a 'number' for heart performance parameters and a positive-negative diagnosis of myocardial ischemia. A seismic sensor captures a substantial series of SCG waveforms within a short time frame. Digitized waveforms are created and processed to create signals in the range of 0 to 50 hertz and 0 to 100 hertz. The waveform are processed in the time domain. The 0 to 100 hertz signal is processed to determine the heart rate which is pulse adjusted and interpolated. The SCG waveforms are processed to synchronize the start point of each waveform. The 0 to 50 hertz signal is then processed for signal segmentation to produce waveform signals, each a heart beat or period in length. The segmented signals are then processed to produce linear prediction analysis (LPA) coefficients. The coefficients establish a numerical model-based representation of the waveform. The LPA coefficients in combination contain all of the information resident in the original SCG waveform. For myocardial ischemia analysis, proper LPA coefficients are used in a pattern recognition algorithm to determine a classification of the patent's waveforms as either normal or ischemic. The Bayesian decision classifier provides an analytical framework and program for classification of SCG waveforms as represented by the LPA coefficients for myocardial ischemia, or other cardiac disease conditions represented in the SCG waveform, and produces a direct negative or positive output. For various cardiac performance parameters, estimation rather than a classification algorithm is used such as a K-Nearest Neighbor pattern recognition technology, and multiple regression estimators and produces estimation for different parameters.

Automated seismic detection of myocardial ischemia and related

A probe useful for invasively monitoring the oxygen saturation level of blood in the tissue walls of an anatomical canal generally includes a chassis with an electrical connector extending from the proximal end of the chassis and terminating at a plug configured for connection to a pulse oximeter box. The probe further includes an optics assembly configured to generate and transmit electrical signals that are indicative of the dynamic oxygen saturation level of blood in the wall tissue. The probe further includes a deployment device attached to the chassis for biasing the optics assembly into the tissue wall of the anatomical canal.

Methods and apparatus for the invasive use of oximeter probes

A probe useful for invasively monitoring the oxygen saturation level of blood in the tissue walls of an anatomical cavity generally comprises a chassis with an electrical connector extending from the proximal end of the chassis and terminating at a plug configured for connection to a pulse oximeter box. The probe further includes an optics assembly configured to generate and transmit electrical signals that are indicative of the dynamic oxygen saturation level of blood in the wall tissue. The probe further includes a deployment device attached to the chassis for biasing the optics assembly into the tissue wall of the anatomical canal and stabilizing the probe within the canal. Further, the oximetry sensing assembly may be configured as part of an esophageal stethoscope having other sensing devices, for example, a temperature sensor, a pacing assembly, and an acoustic monitor.

Oximeter probes and methods for the invasive use thereof

A reflectance oximeter probe is suitably disposed at a distal end of an elongated, substantially flat, semi-rigid chassis configured for insertion into an anatomical canal, for example in the esophagus, rectum or vaginal cavity of a human patient. The reflectance probe may also be suitably employed in many veterinary applications. An electrical connector extends from a proximal end of the chassis and terminates at a plug configured for mechanical and electrical connection to a pulse oximeter box. The reflectance probe includes first and second LED's mounted to an emitter assembly and a detector assembly spaced apart from and mounted substantially coplanar with respect to the emitter assembly. The reflectance probe generates and transmits signals to the oximeter box, the signals indicative of the dynamic oxygen saturation level of the blood perfused mucus membrane tissue.
