Abstract: An electronic sphygmomanometer, which measures blood pressure in accordance with the volume compensation method, detects a cuff pressure inside a cuff attached to a measurement site of the blood pressure. An arterial volume detection circuit detects an arterial volume signal of the measurement site. A drive control unit, after setting the cuff pressure to an initial cuff pressure, servo-controls a cuff pressure adjustment unit so that a volume of an artery becomes constant, based on the detected arterial volume signal. While the servo control is being performed, an arterial volume change amount is detected based on the detected arterial volume signal.

Abstract: A method and apparatus for determining the volume of a pouch formed in a stomach during bariatric surgery comprises a balloon catheter having an inflatable balloon located at a distal end of a catheter for locating in the stomach. A pair of spaced apart stimulating electrodes are located on the catheter within the balloon and a plurality of spaced apart sensing electrodes are located on the catheter between the stimulating electrodes. The balloon in the stomach is inflated by a saline solution to define the interior of the pouch. By applying a constant current signal to the stimulating electrodes, the volume of the pouch is determined from signals read from the sensing electrodes.

Abstract: Devices and methods for detecting disordered breathing involve determining that the patient is asleep and sensing one or more signals associated with disordered breathing indicative of sleep-disordered breathing while the patient is asleep. Sleep-disordered breathing is detected using the sensed signals associated with disordered breathing. The sensed signals associated with disordered breathing may also be used to acquire a respiration pattern of one or more respiration cycles. Characteristics of the respiration pattern are determined. The respiration pattern is classified as a disordered breathing episode based on the characteristics of the respiration pattern. One or more processes involved in the detection of disordered breathing are performed using an implantable device.

Abstract: A blood pressure measuring apparatus includes a cuff member (2) which can be attached to and detached from a blood pressure measurement portion, and a cuff main body (1) including a compression air bladder (8) for pressing the blood pressure measurement portion, a sub air bladder (7), and a pulse wave detection air bladder (5). After pressurization is performed by compression air bladder pressurizing/depressurizing means (22, 23) and sub air bladder pressurizing/depressurizing means (27, 26), depressurization is controlled at the same depressurization rate, thereby reducing the cuff-edge effect and obtaining a pulse wave signal.
