Patent ID: 8083683

Claim:
A pneumatic system for measuring a patient's blood pressure when connected to either a single lumen cuff or a dual lumen cuff wherein said system includes: a blood pressure monitor having a first lumen terminal and a second lumen terminal; a first flow circuit connected to said first terminal that contains a first pressure sensor; a second flow circuit that contains a pneumatic pump for inflating a cuff and a bleed valve for deflating a cuff; a flow director means operatively associated with said second terminal having a first position for directing said pump discharge to said first circuit and isolating said second terminal when a single lumen is connected to first connector wherein said cuff is inflated through and deflated through said single lumen and cuff pressure is sensed by said first pressure sensor, and for automatically moving said flow director to a second position when a first lumen of a dual lumen cuff is connected to the first terminal and a second lumen of said dual lumen cuff is connected to said second terminal wherein said cuff is inflated and deflated through said second lumen and the cuff pressure is sensed by said first pressure sensor.
