Abstract

The present invention relates to a kind of small-sized pump with a discharge valve device and blood pressure meter utilizing the same which can obtain a structure characterized by decreased component number, simplified structure, reduced size and weight, and readiness to assemble with other appliances. The structure is described as follows: A diaphragm (16a) of a pump chamber (15) communicating with a pressurized chamber is arranged inside the pump casing (14); there are discharge valves including a constant-rate discharge valve (12) and a rapid discharge valve (13) used to discharge the air from the pressurized chamber to reduce the inner pressure of the pressurized chamber; the pump chamber (15) and the discharge valves are formed integrally.
