A blood pressure measurement device includes a finger cuff for measuring a blood oxygen saturation level of a subject as physiological information excluding a blood pressure, a pulse wave detecting portion, and an oxygen saturation level calculating portion, where a start of blood pressure measurement in a sphygmomanometer is determined by a comparing and determining portion when a value becomes greater than or equal to a reference value. After the end of the measurement, a time limit for limiting the start of the blood pressure measurement is set. The comparing and determining portion determines not to start the blood pressure measurement within the time limit even if the blood oxygen saturation level becomes greater than or equal to the reference value.

Blood pressure measurement device for measuring at appropriate timing

A cardiovascular risk evaluation apparatus includes a hypoxic acquisition unit for acquiring a measurement result that includes a blood oxygen saturation level measured in a hypoxic period in which the blood oxygen saturation level of a subject is lower than a threshold value, and a blood pressure measured when the blood oxygen saturation level was measured; a non-hypoxic acquisition unit for acquiring a measurement result that includes a blood oxygen saturation level measured in a non-hypoxic period of the blood oxygen saturation level of the subject, and a blood pressure measured when the blood oxygen saturation level was measured; and an indicator acquisition unit for acquiring a cardiovascular risk evaluation indicator for the subject based on the relationship between blood oxygen saturation level and blood pressure, which is based on the measurement results acquired by the hypoxic acquisition unit and the non-hypoxic acquisition unit.

Cardiovascular risk evaluation apparatus

A blood pressure measurement apparatus for measuring blood pressure in a predetermined period includes a blood pressure measuring unit for measuring the blood pressure of a subject, an information acquiring unit for acquiring information that is related to variation in blood pressure and changes in a time-series in the predetermined period, a determining unit for determining whether or not the information acquired by the information acquiring unit satisfies a predetermined condition, and a trigger output unit for, in a case where the determining unit determines that the predetermined condition is satisfied, causing the blood pressure measuring unit to start and execute blood pressure measurement. The predetermined condition is expressed as a function of time that varies and is measured in the predetermined period.

Blood pressure measurement apparatus

A control unit determines the level of sleep of a subject on the basis of biological information measured by a biological information measuring unit starts blood pressure measurement of the subject upon determining that the determined level of sleep satisfies a predetermined condition. The control unit stores the result of the blood pressure measurement in a memory.

Blood pressure measuring apparatus

When a predetermined condition for measurement is selected from a plurality of conditions for measurement by operating one of measurement switches before measuring the blood pressure, a pressure begins to be applied to a bladder in response to the selection and the measurement of the blood pressure starts. The measured data of the blood pressure and the selected condition for measurement are linked to each other and stored in a memory. Because the measurement of the blood pressure starts upon selection of the predetermined condition by operating one of the measurement switches, one operation can serve both as switching to instruct the starting of the measurement and selecting the predetermined condition for measurement. Thus, an additional operation for inputting a condition for measurement is not necessary, and this makes it possible to prevent forgetting to input or incorrectly inputting a condition for measurement from occurring.

Electronic blood pressure monitor and blood pressure measuring system

A blood pressure measurement unit measures the blood pressure and a CPU accordingly stores, in a blood pressure storage unit, measurement data as well as time information regarding the time at which the blood pressure is measured. The CPU calculates, as representative measurement data, the average of a plurality of measurement data stored in the blood pressure storage unit and correlated with the time information indicating a time in the range between nine weeks ago and ten weeks ago, correlates the representative measurement data with time information representing the corresponding week and stores the data with the time information in the blood pressure storage unit. At this time, the CPU deletes from the blood pressure storage unit those measurement data based on which the representative measurement data is calculated.

Electronic blood pressure monitor and method of managing measurement data of electronic blood pressure monitor

A blood pressure measuring apparatus oppresses blood vessels of a human body by an inflating unit through a cuff. When the blood vessels are oppressed through the cuff, a pulse wave superposed on a cuff pressure signal through a cuff pressure detector is detected by a pulse wave detector. The waveform of the detected pulse wave changes similarly to changes of pressure in the oppressed blood vessels in one heartbeat period. The information of the detected pulse wave waveform and the cuff pressure at this time are stored in a memory. A blood pressure calculator determines the scale of pulse wave waveform on the basis of the information stored in the memory, and matches the determined scale of pulse wave waveform with the scale of waveform showing pressure changes in the blood vessels, so that a plurality of timings of coincidence of cuff pressure and blood pressure are detected, and the systolic pressure and diastolic pressure are calculated by using these detected information and stored information of pulse wave waveforms. It is therefore possible to measure blood pressures in a short time.

Provide is a blood pressure meter cuff capable of avoiding an influence of an edge effect by pressurizing only a portion of a blood vessel in the downward vicinity of the body surface to thereby measure a correct blood pressure. A blood pressure meter cuffincludes: a fluid bag into which a fluid is injected; and a fixing tool fixing the fluid bag on a limb of a human body or the like, wherein a width in the axial direction of the limb, of the fluid bag is a value suitable for selectively pressurizing only a portion of a blood vessel present in the downward vicinity of the skin. In a case where pressurization is imposed on only a portion of the radial artery present in the downward vicinity of the body surface and adjacent to a radial styloid process of a wrist, a width, in the axial direction of a limb, of the fluid bag is set to 15 mm or more and 25 mm or less.

Blood pressure meter cuff

A blood pressure monitor associates information representing measuring time input from a clock with measured blood pressure values so as to store them in a memory. Blood pressure values measured in a morning time zone and blood pressure values measured in an evening time zone are grouped based on the time information associated with the blood pressure values so as to be stored in the memory. A data intra-group average calculating section calculates averages of the blood pressure values in the groups, and a risk calculating section calculates a risk value based on the calculated results of the data intra-group average calculating section.

Blood pressure monitor and cardiovascular disease risk analyzing program

Provide is a wrist type blood pressure meter cuff not oppressing the non-selected artery so as to prevent its pulse waves from mixing into pulse waves of the selected artery necessary for measurement, in a cuff used in a blood pressure meter for measuring blood pressures by selecting and oppressing one artery of the wrist. A wrist type blood pressure meter cuff comprises a fluid bag for oppressing a selected artery of either radial artery or ulnar artery located at the wrist by feeding fluid inside to inflate, and a fixing member for fixing the fluid bag at the wrist. By forming a gap between the fixing member and the wrist, the oppressing pressure directly applied from the fixing member to the wrist at which the non-selected artery is located is set smaller than the oppressing pressure directly applied from the fixing member to other position of the wrist when oppressing the wrist by inflating the fluid bag. This gap is produced by a swollen part provided in the fixing member.

Wrist type blood pressure meter cuff

Provided is an electronic blood pressure monitor capable of realizing functions of blood pressure measurement in a shorter time and blood pressure measurement with more of correctness in the same and one construction thereof. The electronic blood pressure monitor includes: an oscillometric measuring section capable of calculating a blood pressure with a high precision using much of biogenic information though a time is required since a blood pressure is calculated during a period in which the cuff pressure is gradually changed; and an SPD measuring section completing measurement in a short time though a fluctuation in precision of measurement arises according to an with less of biogenic information since individual difference a blood pressure is calculated using only one or several pulse waves. Since the oscillometric measuring portion performs a calibration processing for the SPD measuring section simultaneously during measurement thereof, calibrating operation a complicated can be practically excluded.

Electronic blood pressure monitor

A measuring device to measure vascular function of an artery includes a cuff that is attachable to a specified part of a body to constrict the artery, a pulse wave amplitude calculating device that calculates an amplitude of a pulse wave that is synchronous with a heartbeat and is based on a change in a volume of the artery, and an inference device that infers a pressure-to-volume characteristic for the artery based on the amplitude of the pulse wave and a corresponding pressure. A blood pressure meter incorporating the measuring device uses a measure of the vascular function to determine a degree of sclerosis in the artery.

Device to measure vascular function

The amplitude of a pulse wave that appears in a form superimposed upon cuff pressure is detected every beat of a heartbeat in synchronism with the beat not only in the course of depressurization but also in the course of pressurization. The maximum value Amaxi of the pulse-wave amplitude in the course of pressurization is multiplied by a prescribed coefficient to decide a threshold value TH. The threshold value TH is calculated as a value equivalent to a pulse-wave amplitude corresponding to systolic pressure that would be determined in the course of depressurization. After the cuff is pressurized to the target pressure, a transition is made to the depressurizing process. It is judged that cuff pressurization is inadequate if the initial pulse-wave amplitude in the course of depressurization is greater than the threshold value TH. Thus, whether or not cuff pressurization is inadequate can be judged appropriately at all times without any influence due to personal differences or physical condition.

Electronic sphygmomanometer and method of controlling operation of same

The pressure controller stops the pressuring operation when the inside fluid pressure of the cuff exceeds a total pressure of the estimated value and a predetermined value.
