Our objective is to demonstrate the feasibility of an instrument to measure residual urinary bladder volume non-invasively. the instrument is based on ultrasonics and would specifically be designed for low cost, direct digital readout, and ease of use by relatively untrained personnel. the primary… More

Small doppler ultrasonic catheters, 1-2 mm in diameter, previously developed by the investigative team will be used to measure blood flow in vessels, 1-5 mm in diameter, to detect vessel patency after microsurgery. the present phasewill define best positioning site for catheter to vessel, develop… More

The objective is to demonstrate the feasibility of a membrane-sensor system suitable for use in a miniature fiberoptic potassium-ion sensor (optrode) for continuous monitoring in body fluids. potassium levels are commonly monitored during cardiac surgery, diabetic acidosis, renal failures, and other… More

The hard-copy fetal monitor record (fmr) produced and annotated during labor contains the history of the labor and is part of the patients record. the bulk and form of the fmr is unacceptable for the chart, the medical records system, or long-term retention: all are critical to patient management as… More

Current external fetal heart rate monitors provide valuable information. however, they require skilled attention, frequent adjustments, andpatient restraint in order to obtain consistent reliable information. this is because thedoppler signal can only be captured from a small volume in the uterus,… More
