Abstract: A kidney stone specimen collection device having a tubular body with a longitudinal axis, a mesh screen affixed to an interior of the tubular body and extending transverse to a longitudinal axis of the tubular body, a first closure member affixed to one end of the tubular body so as to selectively seal the end of the tubular body, and a second closure member affixed to an opposite end of the tubular body for selectively sealing the opposite end of the tubular body. The tubular body is formed of an impact-resistant generally transparent plastic material. A flow indicator is positioned on a surface of the tubular body so as to be indicative of a direction of urine flow through the tubular body.

Abstract: An automated vascular testing apparatus includes capillary blood flow sensors and blood pressure detection sensors to detect data regarding the blood flow of a patient. Error detection apparatus insures that the blood data sensors are properly connected and that the output signals therefrom are reliable and provide an adequate basis for measurement. A controller monitors the output signals from the sensors and manages the overall operation of the automated testing procedures. The controller memory temporarily stores the output signals from the blood data sensors, along with other miscellaneous data. A video display presents instructions, data, and conclusions based on accepted medical theories to the operator, while a printer optionally reproduces these data in hard copy form.
