Verenpainemittauksessa käytettävän mansetin paineen rajoittaminen

An apparatus and a method for restricting to a proper level the pressure increase in cuffs (7) for use in non-invasive automatic sphyghmomanometry and connectable with a common monitor (1). The apparatus comprises a pump (2) and a cuff (7) in communication therewith that can be replaced with another type of cuff. The pressure of the cuff is increased by means of pump" (2), a valve (8) for releasing the pressure out of cuff (7), a pressure-sensing element (12) for monitoring the development of a cuff pressure, an AC/DC signal separator (13) for separating an AC component from a DC component in a signal received from the pressure-sensing element, and a control element (16) for further processing the information received from the signal separator and for controlling the operation of valve (8). The different cuff types require separate pressure-restricting elements (5 and/or 9), whose maximum accepted set pressures differ from each other and which automatically drop the cuff pressure as the pressure exceeds a set level.
