Claims

[Scope of Claim for Utility Model Registration] (1) A blood pressure monitor that supplies pressurized air to a cuff from an air system and exhausts this pressurized air at a slow rate to measure blood pressure, with a case interposed in the air system. A valve body is provided in the air passage, the valve body is composed of a support part and an adjustment part continuous with the support part, and a hollow part with one end open at the end face of the support part is formed across the tip of the adjustment part. The valve body is divided in the longitudinal direction to form two divided valve bodies, and a slit is formed between the divided faces of the adjustment part, and the divided valve body is made of an elastic body. 1. A slow-speed exhaust valve for a blood pressure monitor, characterized in that the support part is formed thicker than the adjustment part and fitted into the case, and the opening amount of the slit changes depending on the exhaust pressure. (2) The slow exhaust valve in a blood pressure monitor according to claim 1, wherein the slit is formed by a protrusion provided on a dividing surface of the adjustment portion. (3) The slow-speed exhaust valve in a blood pressure monitor according to claim 1, wherein the slit is formed by providing a notch in the dividing surface of the adjustment portion.
