An inflation bulb, suitable for use with sphygmomanometer, is internally hollow, and comprises a gas inlet end and a gas outlet end. An inner side of the gas inlet end forms inwardly protruding lips that are approximately flat. The lips define a gas inlet opening through which exterior air gas is allowed to penetrate the inflation bulb. The gas outlet end includes a gas outlet opening. The gas outlet opening is further connected to a gas intake pipe. When the inflation bulb is pressed, the lips occlude the gas inlet opening, which compels an inner air gas to exit via the gas outlet opening. Once the pressing action is released, the inflation bulb recovers its initial state and causes the lips to open the gas inlet opening. By repeatedly pressing and releasing the inflation bulb, a cuff of the sphygmomanometer is inflated.
