摘要： The present invention provides a technique for continuous measurement of blood pressure based on pulse transit time and which does not require any external calibration. This technique, referred to herein as the ‘Composite Method’, is carried out with a body-worn monitor that measures blood pressure and other vital signs, and wirelessly transmits them to a remote monitor. A network of body-worn sensors, typically placed on the patient's right arm and chest, connect to the body-worn monitor and measure time-dependent ECG, PPG, accelerometer, and pressure waveforms. The disposable sensors can include a cuff that features an inflatable bladder coupled to a pressure sensor, three or more electrical sensors (e.g. electrodes), three or more accelerometers, a temperature sensor, and an optical sensor (e.g., a light source and photodiode) attached to the patient's thumb.

摘要： The present invention discloses a non-invasive blood pressure measurement apparatus and a safety protection method. In addition to a main pressure measurement circuit and a main microprocessor circuit, the measurement apparatus also includes an independently disposed assist pressure measurement circuit and an independently disposed assist microprocessor circuit. In normal measurement, the assist microprocessor circuit periodically samples a cuff pressure via the assist pressure measurement circuit, and compares the measured cuff pressure with a specified overpressure protection value, and if the cuff pressure exceeds the specified overpressure protection value, the assist microprocessor circuit outputs a control signal to open a deflation valve until the pressure falls to below the safety pressure. Compared with the prior art, the method for overpressure protection of the present invention is more direct and has higher accuracy of decision, leading to higher reliability of the overpressure protection and higher safety of the measurement apparatus.

摘要： Provided is a non-invasive electronic method and apparatus for measuring blood pressure, in which the data is processed with an algorithm of non-linear fitting for recovering trend envelope of an oscillating PW by a firmware, so that the trend envelope of PW amplitude can be recovered accurately, and the obtained average pressure shows higher degree of agreement with the real situation in clinic. In this apparatus, a 3-way solenoid valve (20) is arranged between a cuff (10) and a first pressure sensor (30), wherein the common port of the 3-way solenoid valve (20) is connected with the first pressure sensor (30), the normally open port thereof connected with the cuff (10), and the normally closed port thereof connected with the air atmosphere during zeroing process. Moreover, an independent timing circuit (45) is provided additionally. In the measurement method of the present invention, the zeroing is performed with the help of the 3-way solenoid valve (20). Once a state of overtime or overpressure occurs, an gas pump (50) is immediately closed, and a quick-deflation solenoid valve (60) is opened so that the pressure in the cuff (10) is released to ensure safe application.

摘要： A system and method of controlling the pressure within a pressure cuff of a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient, wherein a sensor determines when flow past the tourniquet is occurring so that corrective action may be taken, such as by increasing the pressure in the tourniquet or by notifying an operator of the flow past the tourniquet. The present invention may use an acoustic sensor to detect Korotkoff sounds indicating incipient blood flow past the tourniquet. When such signals are detected, the tourniquet controller may either incrementally increase the pressure in the tourniquet, or if a threshold would be exceeded by such an increase, signal an alarm indicative of the blood flow.

摘要： A method and apparatus are disclosed for the non-invasive measurement, processing and utility of blood pressure cuff oscillation signals from a blood pressure cuff applied to a body part when the blood pressure cuff pressure is at supra-systolic pressures. Oscillometric cardiac pulse waveforms associated with the peripheral artery are monitored during a plurality of cardiac ejection cycles while at supra-systolic pressure, and are measured pneumatically and transduced by an oscillometric pressure sensor. The analog signal is amplified, processed and digitized to provide a recordable waveform that can be analyzed to obtain information relating to the patient's cardiovascular status.

摘要： The invention is in one embodiment an apparatus and a method for measuring the blood pressure of a vertebrate subject. The apparatus uses an inflatable chamber with a sensor to detect signals indicative of a blood pressure of the subject during an inflation interval of the inflatable chamber. If secondary motion or artifact signals are detected, the apparatus and method determine whether the secondary signals are below a predetermined value, and if so, complete the measurement. If the signals indicate that the measurement is not accurate, the system and method immediately institute a measurement of the blood pressure during a deflation interval, which can include a step deflation interval. In the event that the subject is identified as a neonate, the system and method immediately measure using the deflation interval procedure.
