Abstract: A blood pressure measurement apparatus includes a derivation control unit that performs derivation control to derive a blood pressure of a measured person. The derivation control unit includes an envelope extracting unit to extract an envelope of a volume pulse wave based on an arterial volume signal, a differential processing unit to differentiate the envelope with respect to a cuff pressure, a maximum value extracting unit to extract a maximum value of a differential value of the envelope, and a blood pressure decision unit that decides the cuff pressure used for the differential of the maximum value as a blood pressure.

Abstract: An electronic sphygmomanometer, which measures blood pressure in accordance with the volume compensation method, detects a cuff pressure inside a cuff attached to a measurement site of the blood pressure. An arterial volume detection circuit detects an arterial volume signal of the measurement site. A drive control unit, after setting the cuff pressure to an initial cuff pressure, servo-controls a cuff pressure adjustment unit so that a volume of an artery becomes constant, based on the detected arterial volume signal. While the servo control is being performed, an arterial volume change amount is detected based on the detected arterial volume signal.

Abstract: A blood pressure information measurement device includes a cuff (10A) serving as a detection unit. The cuff (10A) includes an air bladder (40), a photoelectric sensor (50), a belt member (20), and a fixing stand (32), and is attached to a living body by wrapping the belt member (20) around a measuring site. The photoelectric sensor (50) optically detects an intra-arterial volume fluctuation, and includes a light emitting element (51) and a light receiving element (52). The fixing stand (32) includes a base portion (32a) with a sensor attachment surface (32a1) attached with the photoelectric sensor (50), and a guide portion (32b) arranged projecting out from the base portion (32a) toward the sensor attachment surface (32a1) side, and having a distal end placed at a body surface near the measuring site in the attachment state of the cuff (10A).

Abstract: A pulse wave measurement electrode unit includes an electrode group and a supporting member. The electrode group includes a first electrode portion including a first current application electrode and a first voltage measurement electrode, and a second electrode portion, positioned spaced apart from the first electrode portion, including a second current application electrode and a second voltage measurement electrode. The supporting member supports the electrode group such that contacting surfaces of the electrodes with respect to a living body are arranged substantially on an identical plane. The electrodes are arranged lined in a direction an artery extends when the pulse wave measurement electrode unit is applied to the living body. According to such a configuration, a pulse wave measurement electrode unit having a simple configuration and enabling high precision volume pulse wave measurement can be provided.

Abstract: For each blood pressure measurement, measured blood pressure data output by a blood pressure calculation unit is stored in a memory. On this occasion, the number of times of measurement is incremented by a number of times of measurement update unit, and data on the incremented number of times of measurement is stored in the memory. Based on information read from the memory, a number of times display data generation unit generates display data for a count result of the number of times of blood pressure measurement, and supplies the generated display data to a display control unit. Based on the supplied data, the display control unit displays the count result of the number of times of blood pressure measurement on a display unit.

Abstract: A blood pressure monitor includes a switch for designating a user who is a subject. The switch for designating a user also serves as a power switch. When this switch is pressed as the first step for blood pressure measurement, the blood pressure monitor is turned on. The blood pressure monitor does not operate even when a switch for blood pressure measurement operation or a switch for display of recorded past measurement values is pressed before the switch for designating a user is pressed.

Abstract: An electronic blood pressure monitor has a switch detecting whether a front cover is open or closed. When the front cover is opened by a subject, the switch detects that the cover is opened, and outputs a detection signal to a control portion. In control portion a CPU operates in response to the detection signal being received to cause a power supply switch LED to flash on and off/turn on. This indicates that of a variety of switches of a console, the type of manipulation switch that should first be operated is a power supply switch.

Abstract: An electronic blood pressure monitor includes a display and a console. The console has a plurality of manipulation switches. The display has displaying areas associated with the manipulation switches, respectively, for displaying indications provided as the manipulation switches are operated. In operation, the electronic blood pressure monitor displays on display in a predetermined area a blood pressure value obtained by measuring blood pressure. The console has a user selection switch group, a measuring switch and a record recalling switch, and these manipulation switches and the displaying areas provided on the display and associated with the switches are adjacently arranged, respectively.

Abstract: A substrate support and method of fabricating the same are provided. Generally, one method of fabrication includes assembling a subassembly comprising a first reinforcing member and a heating element, supporting the subassembly at least 40 mm from a bottom of a mold, encapsulating the supported subassembly with molten aluminum, and applying pressure to the molten aluminum. Alternatively, a method of fabrication includes assembling a subassembly comprising a stud disposed through a heating element sandwiched between a first reinforcing member and a second reinforcing member, supporting the subassembly above a bottom of a mold, encapsulating the subassembly disposed in the mold with molten aluminum to form a casting, forming a hole in the casting by removing at least a portion of the stud, and disposing a plug in at least a portion of the hole.

Abstract: A virtual machine system is provided with a control program for concurrently operating a plurality of OSs (Operating Systems). The object is to suppress the overhead produced when simulating privileged instructions for controlling program status words (PSWs). For this purpose, there is provided simple hardware, in place of the software control conventionally used, including a modification register for storing information required to modify the current PSW information and a pending register for storing pending interrupt information for communication to the corresponding OS.
