A blood pressure measurement cuff includes a belt-like body including an outer fabric and an inner fabric facing each other to form a bag shape, the belt-like body housing a fluid bag, an elliptical ring member having one side attached to a region adjacent to one end of the belt-like body, a retaining member provided to a region adjacent to the other end of the belt-like body, and a fixing member provided to a front surface of the outer fabric of the belt-like body. The retaining member includes a projection part that is flexible and projects outward of the belt-like body in a thickness direction Z, and support parts, each being flat plate-like, contiguous with a base of the projection part, and attached along the region adjacent to the other end of the outer fabric.

Blood pressure measurement cuff and method for manufacturing same

A blood pressure monitor cuff is formed by stacking an outer circumferential layer arranged on a side opposite to that of a measurement site and a fluid bladder arranged on the measurement site side. The outer circumferential layer and the fluid bladder are formed of an elastomer material. Two edge portions in a lengthwise direction of the outer circumferential layer protrude in a thickness direction toward the measurement site. The fluid bladder includes a base layer that opposes the outer circumferential layer and a top layer overlapping with the base layer, and the edge portions of the base layer and the top layer are welded together forming a bladder shape. Additional sheets are welded in the thickness direction to the welded edge portions of the top layer and the base layer. The fluid bladder is arranged between the two edge portions of the outer circumferential layer in the width direction.

Blood pressure monitor cuff, method for manufacturing the same, and blood pressure monitor

A blood pressure measurement method includes wrapping a cuff around a site. The cuff includes: a first bladder that swells due to receiving fluid and is arranged at an outer surface of the site that corresponds to a first half surface where an artery is; and a second bladder that swells due to receiving fluid and is arranged at the outer circumferential surface of the measurement site that corresponds to a second half surface opposite to the first half surface. During inflation, the pressure of the second bladder is made larger than the first bladder by supplying more fluid such that the stroke amount by which the second fluid bladder swells is larger in the thickness direction. Then, the two bladders are inflated at equal rates. In the process of inflating, or in the process of deflating at rates equal to each other after inflating, blood pressure is measured.

Fluid bladder, blood pressure measurement cuff, blood pressure monitor, and blood pressure measurement method

A fluid bladder includes multiple segment bladders that are each formed by folding one sheet in half in a width direction X extending along an artery passing through the measurement site, welding or adhering edge portions on a side opposite to the folding location for folding in half, and welding or adhering edge portions in a lengthwise direction Y. The multiple segment bladders are stacked in a width direction orthogonal to the measurement site and integrated, and the folding locations are arranged alternatingly on opposite sides in the width direction.

Fluid bladder, fluid bladder manufacturing method, blood pressure measurement cuff, and blood pressure monitor

An appliance includes a belt that is worn by being wound around a wrist. The appliance includes: at least a first display region that is positioned in an area of the belt that corresponds to a volar-side surface or a radius-side surface of the wrist; and a second display region that is positioned in an area of the belt that corresponds to a back-side surface of the wrist. During a blood pressure measurement period, first control for displaying ongoing blood pressure measurement information only on the first display region is performed, and during a period other than the blood pressure measurement period, second control for displaying information that needs to be displayed on the first or second display region is performed.

Appliance

A fluid bladder has a first fluid bladder region that inflates due to receiving a supply of fluid and is contained in a portion of an outer circumferential surface of a measurement site in a lengthwise direction of a cuff, the portion corresponding to a first half surface, where an artery is. Also, the fluid bladder has an expansion region that is expanded due to an action from outside, and is contained at a portion of the outer circumferential surface of the measurement site that corresponds to a second half surface, in the lengthwise direction of the cuff. During inflation for blood pressure measurement, a stroke amount by which the expansion region expands is larger in the thickness direction than a stroke amount by which the first fluid bladder region swells.

With the blood pressure meter of the present invention, a pump unit is connected via a first fluid path to a fluid bladder. The first fluid path extends straight in the Z direction between the pump unit and the fluid bladder, sends air supplied from the pump unit to the fluid bladder or sends air inside of the fluid bladder to a valve.

Blood pressure meter

A bodily information measurement apparatus includes a band-shaped belt to be wrapped around a measurement site; a main body that is connected to a base end portion in the lengthwise direction of the belt and on which a pressure detection unit and a fluid supply unit are mounted; and a fastening unit for fastening the base end portion and the leading end portion of the belt. The belt is formed by stacking an outer circumferential layer and a fluid bladder for compressing the measurement site. The bodily information measurement apparatus is attached to the measurement site due to the base end portion and the leading end portion being fastened by the fastening portion in a state in which the fluid bladder and the leading end portion of the belt overlap.

Bodily information measurement apparatus

A blood pressure measurement device includes a cuff and a control unit. The cuff includes a first securing portion, provided on one surface of the cuff, for securing the cuff to the measurement area in a wrapped state, and a second securing portion, provided on another surface of the cuff, for securing the cuff to the measurement area in a wrapped state. At least one of the first securing portion and the second securing portion includes an electromagnet portion. The control unit secures the cuff to the measurement area by controlling a magnetic force emitted from the electromagnet portion and causing the second securing portion to be attracted to the first securing portion.

Blood pressure measurement device

Sphygmomanometer with wireless communication device

A first oscillation circuit and a second oscillation circuit are connected to a first pressure sensor and a second pressure sensor, respectively, and oscillate based on the capacity values of the corresponding pressure sensors. The first oscillation circuit and the second oscillation circuit operate in response to instruction from a CPU. The one of the first oscillation circuit and the second oscillation circuit that has received an activation signal from the CPU outputs a signal having a frequency that corresponds to the capacity value of the corresponding pressure sensor. An adjustment circuit is connected to the first oscillation circuit and the second oscillation circuit, and allows one of the frequency signals to pass therethrough, outputting the signal to the CPU.

Electronic sphygmomanometer

In an electronic sphygmomanometer, the thickness of the second connection tube is set to be lower than the thickness of the first connection tube, and therefore, even if error has occurred in the structural dimensions of the pressure sensor air tube, the error can be absorbed as a result of the second connection tube extending/contracting. It is therefore possible to provide an electronic sphygmomanometer that includes, in a structure in which a pressure sensor used in the electronic sphygmomanometer is disposed, a peripheral structure for the pressure sensor that can improve the reliability of blood pressure measurement values.

In an electronic sphygmomanometer, a first pressure sensor and a second pressure sensor are disposed on a front surface side that serves as a first main surface of an internal circuit board, following a horizontal direction (the X direction) that is orthogonal to the direction in which the internal circuit board is sloped. As a result, the first pressure sensor and the second pressure sensor are disposed having the same height position. It is therefore possible to provide an electronic sphygmomanometer that includes, as a structure in which a pressure sensor used in the electronic sphygmomanometer is disposed, a peripheral structure for the pressure sensor that can improve the reliability of blood pressure measurement values.
