Non-invasive cerebral perfusion increasing device

A non-invasive cerebral perfusion increasing device including four cuffing pad units and a control unit which is connected to the cuffing pad units and is equipped with a blood pressure sensing module and a compression control module. In the non-invasive cerebral perfusion increasing device each cuffing pad unit respectively includes a compression pad, a compression control member and a blood pressure sensing member. The blood pressure sensing module uses the blood pressure sensing members to sense the systolic blood pressure values of the portions of each of the limbs where they are attached and the compression control module controls the degree of compression of each compression pad by controlling the compression control member to a setting desired by the user based on the sensed blood pressure value, such that the blood flow applied to the limbs is blocked and, indirectly, cerebral perfusion is increased.

A method is directed to continuously, non-invasively, and directly measuring blood pressure, and includes providing a calibrated measurement device having a blood-flow control balloon and a sensor array. The method further includes placing the sensor array in a non-invasive manner over the surface of a patch of skin connected to an artery by adjoining soft tissues and inflating the blood-flow control balloon with a controlled amount of pressure. In response to the inflating of the blood-flow control balloon, changes in the artery geometry and forces are detected, via the sensor array, during a heartbeat cycle. The changes correspond to spatio-temporal signals from the artery or in the adjoining soft tissues. The spatio-temporal signals are measured and processed, via a controller, to determine blood-pressure parameters.
