Magneto-rheology to Lower Blood Pressure

The MBPL device for clinical trials is made with modification of an electromagnet: A bore of 10cm diameter was made to go through the frame and poles. The device can produce a magnetic field close to 1.0 T inside the bore, which is along the axis direction. The trial for each subject takes about 20-30 minutes. To start with, the subject's blood pressure is measured first as the baseline. Afterwards, the subject places his/her right arm into the bore of the electromagnet for treatment while the blood pressure is monitored with the left arm. The magnetic treatment lasts about 15 minutes and will lower the subject's blood pressure. In order to see how long the effect lasts, the subject needs to return and measure the blood pressure again 24 hours after the treatment. The clinical trials are non-invasive. There is no medicine or surgery involved.
