。[Scope of Claim for Utility Model Registration] An exhaust valve that discharges the air inside the cuff that compresses a part of the body during blood pressure measurement, including a high pressure chamber that communicates with the cuff and a low pressure chamber that communicates with the atmosphere through an exhaust port. an air flow path that communicates the high pressure chamber and the low pressure chamber, and is arranged to partition the high pressure chamber and the low pressure chamber, and the pressure difference between the high pressure chamber and the low pressure chamber exceeds a predetermined value. and an elastic valve body that closes the exhaust port and is deflected to open the exhaust port when the pressure falls below a predetermined value, thereby keeping the pressure difference between the high pressure chamber and the low pressure chamber substantially constant at all times. Exhaust valve in non-invasive blood pressure measurement device.
