Blood pressure cuff device

Abstract

To provide a blood pressure measurement cuff device that can shorten the time required for supplying and discharging air to multiple air bags while suppressing the complexity and size of the supply and discharge section. [Solution] The blood pressure measuring cuff device of the present disclosure comprises a cuff bag, an outer peripheral bag provided on the outer circumference of the cuff bag, a cuff bag supply / discharge section for supplying and discharging fluid to the cuff bag, an outer peripheral bag supply / discharge section for supplying and discharging fluid to the outer peripheral bag, and a flow path switching valve having at least a first port, a second port, and a third port, and capable of taking a first state in which the first port and the second port are in communication and the first port and the third port are blocked, and a second state in which the first port and the second port are blocked and the first port and the third port are in communication. The cuff bag supply / discharge section is connected to the first port of the flow path switching valve, the cuff bag is connected to the second port, and the outer peripheral bag and the outer peripheral bag supply / discharge section are connected to the third port.
