A method and apparatus for performing human and animal surgery in which the tissue field including all soft tissue fluid space interfaces can be visualized along with other soft tissue features by appropriate ultrasonic visualization means such as transmitting a scanning ultrasonic beam and receiving echoes from the desired areas and presenting a picture of said areas on a suitable display monitor such as a cathode ray tube for two-dimensional presentation where the presentation may be compared ...

A noninvasive pressure monitor for measuring the pressure in a hydraulic circuit, such as an extracorporeal blood circuit, includes an aperture sealed by a membrane which offers substantially no resistance to pressure and a pressure sensitive transducer in contact with the membrane for providing a more direct measurement of the pressure.

A patient to be treated for the presence of Campylobacter pylori in the stomach and/or duodenum ingests a quantity of urea and after about 10 minutes exhales into breath collection apparatus to provide a breath sample of alveolar air, collected during the last part of the exhalation. Immediately upon issuing from the patient the expired breath is passed in contact with a preferably solid-state body of alkaline hygroscopic material, e.g. sodium hydroxide, that substantially removes water vapor fr...

An apparatus, product formulation, and method for improved dermal permeation of pharmaceuticals wherein the apparatus includes a thin drug formulation reservoir and a heat-generating chamber separated by a first non-permeable wall, wherein the reservoir and chamber are formed in or supported by a housing. The drug formulation reservoir houses or is capable of housing a predetermined amount of a formulation containing pharmaceutically-active agent(s). The heat-generating/temperature-regulating ch...

A noninvasive optical oximeter for measuring oxygen saturation of arterial blood. A sample of blood is illuminated with light at two different wavelengths. Light reflected by the blood is sensed by a photodetector and an output signal is created in response thereto. The output signal is processed to form a quotient representing the AC components of the reflected light at each wavelength. The oxygen saturation of the blood is calculated by correlating this quotient with an oxygen saturation refer...

The noninvasive measurement system provides a technique for manipulating wave data. In particular, wave data reflected from a biological entity is received, and the reflected wave data is correlated to a substance in the biological entity. The wave data may comprise light waves, and the biological entity may comprise a human being or blood. Additionally, a substance may comprise, for example, a molecule or ionic substance. The molecule may be, for example, a glucose molecule. Furthermore, the wa...

A sling for use with a noninvasive blood pressure monitor which is designed to minimize contact by external objects with an inflatable cuff which surrounds a patient's limb during blood pressure measurements. The sling comprises an arm rest having supporting straps for supporting the patient's limb at at least two locations so as to define an unsupported space therebetween adapted to accept the inflatable cuff such that the inflatable cuff does not touch the straps or external objects. Preferabl...

An ultrasonic probe for insonifying the ascending aorta of a supine or reclining human patient. The probe has a head housing transducers for insonifying the patient's ascending aorta and for intercepting doppler-shifted energy reflected from the proximate and distal walls of the ascending aorta and from blood flowing through the aorta. The transducer head is integral with and extends below the handle of the probe, facilitating the manipulation of the probe and alignment of the beam of ultrasonic...
