ABSTRACT:
Devices for and methods of pressurizing or depressurizing a particular pressurizable container or housing in a substantially linear, fixed manner independent of the pressurized volume of the container are disclosed herein. These devices are especially suitable in an arrangement for taking blood pressure in which a cuff wrapped around a body part of a patient is pressurized or alternatively depressurized to detect the patient's systolic and diastolic pressures. The device acts on the cuff so that the latter is pressurized or depressurized in a substantially linear, fixed manner independent of the pressurized volume of the cuff, that is, independent of the size of the cuff.
