Abstract: A system for monitoring the physical and chemical properties of urine in the urinary bladder and functioning of the bladder. For example, the system can include sensors for pressure, temperature, pH, various different chemical constituents of urine, sodium, potassium, glucose, drug markers, drug metabolites, specific gravity, proteins, leukocyte esterase, nitrites, urobilinogen, whole or crenated blood cells, ketones, bilirubin, turbidity or color, the sensors being connected to transmission means for delivering signals representative of the properties detected by the sensors.

Abstract: A blood pressure monitor includes a main body provided with a power switch and an inflating switch, a cover mounted on the main body in an open-and-close fashion and on an inner wall thereof provided with a display, and a cuff secured to the main body as a single unit. When the cover is closed during not using the monitor, the power and inflating switches are covered with the cover. When the cover is opened for use, the display appears. Thus, the blood pressure monitor provides avoidance of unexpected actuation of the power and inflating switches, improvement of operation of the switches and a view angle of the display, improved assembling work of the monitor, and simplification of repair and replacement in the monitor.
