The invention provides a system and method for monitoring blood pressure. The system includes a cuff-free non-invasive portable blood pressure monitoring device, a processor configured to process in real-time signals obtained by the portable blood pressure device to produce one or more processing products, and a portable monitor having a display displaying in real-time one or more of the processing products. In the method of the invention, a blood pressure signal is obtained from a cuff-free non-invasive portable blood pressure monitoring device. Signals obtained by the portable blood pressure device are processed in real-time to produce one or more processing products that are displayed in real-time on a display of a portable monitor. The method and system of the invention may be used in the management of hypertension.

A therapy device having a blood pressure device and a regulating device for a time-variable regulation of the blood pressure, which decides, during a therapy procedure, dependent on detected blood pressure value, whether the blood regulation is continued with hypothetical or with real blood pressure values. The regulating device processes various categories of blood pressure values, i.e. blood pressure values obtained by the regulating device according to an implemented time schedule, blood pressure values requested by measurement and evaluation device, and blood pressure values requested by medical staff. Besides the regular triggers (RT) generated at regular intervals, the irregular triggers (IRT) and the quasi-regular triggers (QRT) requested externally at respective times are also evaluated.

The invention relates to the field of blood pressure devices, in particular to a hydraulic analog device for an invasive blood pressure test. The hydraulic analog device comprises a master control processing module, wherein a blood pressure analog module is connected to the master control processing module, a signal feedback module is further connected between the blood pressure analog module and the master control processing module, the master control processing module is used for controlling the blood pressure analog module to conduct blood pressure state analog, and the signal feedback module is used for feeding back the blood pressure state. According to the hydraulic analog device, the pressure in a hydraulic analog cavity is changed constantly, so that dynamic blood pressure analog is completed; information which is fed back is compared with information detected by an invasive blood pressure detection device, so that the accuracy of the invasive blood pressure detection device is detected; by means of hydraulic analog of invasive blood pressure, the accuracy of invasive blood pressure analog can be effectively improved, true analog of the invasive blood pressure state can be realized, and the accuracy of the invasive blood pressure detection device can be detected accurately; during research and development of the invasive blood pressure detection device, the accuracy of invasive blood pressure detection conducted by the device can be monitored at any time, and therefore the research and development efficiency of the invasive blood pressure detection device is improved.

The invention provides a portable blood pressure meter, which comprises a case, a power supply module, a blood pressure measuring module, a blood pressure processing module and a cuff belt, wherein the blood pressure measuring module is used for collecting blood pressure signals, the blood pressure processing module is used for processing the blood pressure signals, and the power supply module, the blood pressure measuring module, the blood pressure processing module and the cuff belt are simultaneously arranged in the case. The portable blood pressure meter has the advantages that the cuff belt and the blood pressure meter are integrated, the size of the blood pressure meter is reduced, and the portability of the blood pressure meter is improved.

A calibration device (8) is connected to a blood-pressure gauge (1) by means of an air tube (10) and a communication cable (11). When a connection is detected, the calibration device (8) causes a valve (22) of the blood-pressure gauge (1) and a valve (812) of said calibration device (8) to close, applies pressure inside the air tube (10) and measures the pressure inside the air tube (10). Air leakage from the blood-pressure gauge (1) is determined by an air leakage determination unit (802) on the basis of changes in pressure. The calibration device (8) causes the internal pressure at a pressure sensor (23) of the blood pressure gauge (1) to be measured and receives the measurement result by means of a communication interface (815), and the result of an instrumental error test of the blood-pressure gauge (1) is determined by an instrumental error determination unit (804) on the basis of the difference between the applied pressure and the internal pressure. If the instrumental error test is determined to have failed, a control signal is output to the blood-pressure gauge (1) by a calibration unit (805), and the output value of the pressure sensor (23) is calibrated.

The invention discloses a wrist wearable manometer. The wrist wearable manometer according to the present invention comprises: a wrist collar having a wrist strap for being worn on a wrist; and a blood pressure measurement sensor provided on the wrist collar. The wrist strap may include: a hard strap frame bent into a predetermined shape to wrap around a portion of the wrist; and a flexible connecting strap fixed to the strap frame and supported by the strap frame. And the strap frame forms a skeleton of the wrist collar. In addition, the wrist sleeve ring is provided with a tightening device. Moreover, the tightening device selectively tightens the wrist collar, so that the wrist collar presses the wrist.

A biological analysis device includes: a pulse pressure calculation unit that calculates a pulse pressure index related to a pulse pressure of a biological body; an average blood pressure calculation unit that calculates an average blood pressure index related to an average blood pressure of the biological body; and a blood pressure calculation unit that calculates a systolic blood pressure and a diastolic blood pressure in accordance with the pulse pressure index and the average blood pressure index. At least one of the pulse pressure index and the average blood pressure index is calculated in accordance with a blood flow index which is calculated from an intensity spectrum related to a frequency of light reflected and received from an inside of the biological body through radiation of a laser beam and is related to a blood flow of the biological body.
