    摘要: The present disclosure relates to a device and a method for blood pressure measurement, the device (12) comprising a pressurizing unit (30), that is arranged to supply, via at least one supply line (32), a wearable cuff (14) which is arranged to pressurize a measurement site (16) of a subject of interest, a pressure detection unit (40) that detects a cuff pressure (p2) in a direct or mediate fashion, a control section (50) comprising a feed forward 5 controller (64) arranged to output a target inflation flow signal based on a desired inflation rate (or pressure), a feedback controller (62) arranged to minimize the error between a target inflation rate (or pressure) and an actual inflation rate (or pressure), wherein the output of the feed forward controller (64) and the output of the feedback controller (62) are combined to drive the pressurizing unit (30), and a blood pressure determination unit (100) arranged to calculate a blood pressure value based on the cuff pressure (p2) detected by the pressure detection unit (40) during inflation when the cuff pressure (p2) is increased by the pressurizing unit (30) in accordance with a defined pressurizing regime.

    摘要: A blood pressure measuring auxiliary device, a blood pressure measuring equipment and a design method therefor are provided. During a blood pressure measurement, the measured pressure values and beating sound are recorded, so that the recorded pressure values and sound may be played back, which improves the accuracy of the auscultatory method; and the parameters used in the oscillometric method may be adjusted, which improves the accuracy of the oscillometric method. The blood pressure measuring auxiliary device is arranged so that it can be connected with a pressuring device of a sphygmomanometer (5), and comprises a sensing module (1), a communication module, and an audio collection module (2). The sensing module (1) is used for sensing the pressure at the joint between the blood pressure measuring auxiliary device and the pressuring device and outputting a pressure signal to the communication module. The communication module is used for receiving the pressure signal to be transmitted thereby to a terminal equipment (6). The audio collection module (2) is used for collecting the sound at a measured site and outputting an audio signal to the terminal equipment (6).

    摘要: A blood circuit having a pressure measurement portion connected to a pressure measurement device (3,6, 12) includes: a first measurement portion (5, 11) provided downstream of a pumping segment (4); and a second measurement portion (2) provided upstream of the pumping segment. The first measurement portion (5, 11) includes: a first housing having a tubular shape; and a first flexible membrane having a tubular shape and provided in the first housing. The second measurement portion (2) includes: a second housing having a tubular shape; and a second flexible membrane having a tubular shape and provided in the second housing. A space between the first flexible membrane and the first housing is larger than a space between the second flexible membrane and the second housing in an initial state before permitting the blood to flow.
