After the device energized, at first carry out not shown self-initial diagnosis and handle, carry out the first value of device.Afterwards, measure beginning switch S T, begin to handle by pushing.
In step S401, read a hoop bag pressure P, in step S402, whether the residual pressure of judging hoop bag 1 is in setting.When residual pressure surpasses setting, in step S423, " residual pressure mistake " is presented on the LCD14.When residual pressure is in setting, in step S403, use keyboard 16 to set the pressurization value (for example big value) of hoop bag than the maximal blood pressure value of 120～210mmHg, in step S404, light quantity and gain setting are predetermined value.
After the setting of pressurization value and light quantity, gain finishes, in step S405, S406, close anxious valve 4 and little valve 5.In step S407, beginning driving pressure pump 3, (boosting) begins to pressurize.
In step S408, judge whether hoop bag pressure is higher than the pressurization value U that sets in step S403.When not being P＞U, proceed pressurization.When P＞U, in step S409, make force (forcing) pump 3 stop action.
In step S410, open little valve 5.The beginning of the metering process when this is decompression (blood pressure lowering), (for example 2～3mmHg/sec) begin to reduce hoop bag pressure with constant speed.Simultaneously, the detection of the acceleration that beginning is undertaken by body movement checkout gear (acceleration transducer) utilizes first blood pressure to determine that device (photoelectricity pulse mode) and second blood pressure determine that device (pressure pulse mode) begins the detection of pulse.Determine in the device at first blood pressure, utilize light-emitting component 8a to the blood vessel irradiates light, accept reflected light by photo detector 8b by blood flow reflected, detect this light interception data (volume reflection that changes according to endovascular blood flow) as the photoelectricity pulse, simultaneously, determine in the device that at second blood pressure pressure transducer detects the vibration amplitude that changes according to the i.e. compressing amount of air pressure in the hoop bag (air pressure in the hoop bag that vibrates by the hoop bag corresponding to the vibration of the blood vessel wall of beating) as pressure pulse.In step S411, carry out the date processing of each functional device during this.Respectively photoelectricity pulse signal and pressure pulse signal application predetermined algorithm are carried out the measurement of maximal blood pressure and minimal blood pressure.In step S412, the detection of minimal blood pressure value has or not when differentiating decompression.For the minimal blood pressure value that goes out according to photoelectricity pulse data and pressure pulse DATA REASONING respectively,, proceed metering when both do not finish when detecting.In step S413, differentiate hoop bag pressure and whether be lower than predetermined value L (for example 40mmHg).When not being P＜L, then also be in normal measuring range, flow process turns back to step S411.And when P＜L, hoop bag pressure has been lower than normal measuring range, therefore, when the two all can't obtain normal data when photoelectricity pulse signal and pressure pulse signal (for example determined maximal blood pressure value is that 40mmHg is with inferior), in step S414, will " measure wrong " and be presented on the LCD14.At this moment, the then additional if necessary details such as " abnormal signals during decompression " that show.In step S415, open anxious valve 4.
