| 20090012411 | Method and apparatus for obtaining electronic oscillotory pressure signals from an inflatable blood pressure cuff - A method and apparatus are disclosed for the non-invasive measurement, processing and utility of blood pressure cuff oscillation signals from a blood pressure cuff applied to a body part when the blood pressure cuff pressure is at supra-systolic pressures. Oscillometric cardiac pulse waveforms associated with the peripheral artery are monitored during a plurality of cardiac ejection cycles while at supra-systolic pressure, and are measured pneumatically and transduced by an oscillometric pressure sensor. The analog signal is amplified, processed and digitized to provide a recordable waveform that can be analyzed to obtain information relating to the patient's cardiovascular status. | 01-08-2009 |
| 20090099466 | METHOD AND SYSTEM FOR AUTOMATIC CUFF TYPE DETERMINATION - A method for identifying a non-invasive blood pressure cuff type is disclosed herein. The method includes inflating a cuff and obtaining a first pressure measurement in a non-invasive blood pressure system while inflating the cuff. The method also includes obtaining a second pressure measurement in the non-invasive blood pressure system while inflating the cuff and identifying a cuff type based on the first pressure measurement and the second pressure measurement. A corresponding blood pressure monitoring system is also provided. | 04-16-2009 |
| 20090124912 | Tourniquet Apparatus for Measuring Limb Occlusion Pressure - Improved tourniquet apparatus for measuring a patient's limb occlusion pressure includes an inflatable tourniquet cuff for encircling a limb at a location and to which a tourniquet instrument is releasably connectable. The instrument includes pressure sensing for producing a cuff pressure signal indicative of the level of pressure in the cuff, a pressure regulation mechanism communicating with the cuff and responsive to the cuff pressure signal for moving fluid into and out of the cuff, thereby regulating the pressure in the cuff, a blood flow transducer for producing a blood flow signal indicative of blood flow past the cuff, and limb occlusion pressure means responsive to the blood flow signal and the cuff pressure signal for increasing the cuff pressure level until blood flow indicated by the blood flow signal decreases to a level less than a minimum detection threshold, and then suspending fluid movement into and out of the cuff to produce a limb occlusion pressure value that is indicative of a pressure in the cuff when the fluid motion is suspended. | 05-14-2009 |
