A system for determining a blood pressure value of a user including a sensor adapted to receive a signal from the user and a processor. The processor is preferably programmed to perform operations that include monitoring a safety condition of the sensor, initiating the sensor to collect the signal, monitoring a quality of the signal received from the sensor, generating a compressed signal from the signal, delivering the compressed signal as an input to a model for determining the blood pressure value, and receiving the blood pressure value from the model. In a preferred configuration the system allows calibrationless detection of blood pressure with video acquisition platform.

A blood pressure measuring device and a health degree evaluating device in which a patient can easily grasp the onset risk of a cardiovascular disease. A sphygmomanometer (10) has a cuff (14), a sensor (24), a control section (30), and the like as a blood pressure measuring unit, and a storage section (32) that stores blood pressure values. The control section (30) calculates an index related to the health degree of a subject based on a plurality of blood pressure values and their fluctuation characteristics stored in the storage section (32).

A cuff for measuring blood pressure by being wound around a portion to be measured, the cuff being characterized by being provided with: a bag-shaped exterior portion having a circumferential direction, which is the direction in which the cuff is wound around the portion to be measured, and a width direction, which is the direction orthogonal to the circumferential direction, the width direction being the direction in which the cuff is wound around the portion to be measured; the outer side surface becomes the outer side when the cuff is worn, and the inner side surface becomes the inner side when the cuff is worn; a fluid bag accommodated in the exterior part; and a shackle fastener which is provided on the surface of the exterior part and which is provided with scales for dividing the exterior part in the circumferential direction on the surface of the exterior part, the cuff being configured so as to be able to determine where a prescribed site of the cuff is located at the scales when the cuff is worn.

Techniques for multi-sensor differential measurement for blood pressure determination are described. In one or more implementations, sensor data is received from a plurality of sensors positioned at different locations on a body. A time delay of a physiological event at two or more locations on the body is determined based on the sensor data. At least one differential measurement between the two or more locations is calculated based on the time delay. A blood pressure measurement is determined based on the at least one differential measurement.

The present application provides a blood pressure measuring cuff which is excellent in durability and easy to use. The blood pressure measuring cuff (1) comprises: a belt-shaped body (10) formed by enclosing an air bag (7) in an outer cloth (11) and an inner cloth (12) opposite to the outer cloth (11); a first opening portion (15) provided in the outer cloth (11); and a first hook-and-loop fastener (5) fused to the outer cloth (11) in a state in which the first opening portion (15) is closed from the inner side of the belt-shaped body (10) and a loop surface (5k) of the first hook-and-loop fastener (5) is exposed from the first opening portion (15).
