A rubber bulb is used for pumping air into the cuff.

Air is pushed into the cuff when you squeeze the bulb. The pressure in the cuff will be not high enough after only one squeeze, however. A few squeezes are necessary to increase the pressure to the desired level. To prevent the air in the cuff flowing back into the bulb, a one-way valve is built in the housing of the pressure release valve. Since air goes out of the bulb, we will refer to it as the outlet valve.
