摘要： The present invention provides a PHHM for the measurement of a subject's BP and, optionally, one or more other vital signs, comprising a housing located on a PHHCD or a hand-held component of a computing system; a blood flow occlusion means located in the housing such that, when the housing is located on the PHHCD or the hand-held component, an open surface of the blood flow occlusion means is available to be pressed against a body part of the subject or to have a body part of the subject pressed against it; a pressure sensor adapted to provide an electrical signal indicative of the pressure applied to or by the open surface; a means for detecting the flow of blood in the body part of the subject when pressure is applied to or by the open surface; and means for receiving electrical signals from the pressure sensor and the blood flow detecting means and for transmitting electrical signals indicative of the pressure and blood flow to the processor of the PHHCD or the computing system, wherein the processor of the PHHCD or computing system is adapted to process signals acquired by the pressure sensor and the blood flow detecting means to provide at least a measurement of the BP of a subject, the processor is further adapted to carry out a process to measure a DBP value and a SBP value, the DBP and the SBP values are estimated in such a way that the difference between the measured optical signals and those that would be generated by the estimation of the DBP and SBP values is minimized or the DBP and the SBP values are estimated in such a way that the difference between the measured incremental pressure signals and those that would be generated by the estimation of the DBP and SBP values is minimized. The present invention also provides alternative PHHMs and SADs for use in such PHMS.
