Abstract
A vest for positioning medical instrumentation about the human or animal torso to provide ambulatory monitoring of patient cardiac functions or administration of medication or therapy with reasonable freedom of movement while maintaining precise positioning of the instrumentation relative to the torso. The vest functions to provide accurate placement of such instrumentation as a radioactive emission sensor for monitoring ejection fraction. The vest typically includes a sheet of a dimensionally rigid material such as a low density polymer tailored to fit between neck and hips and to surround the torso, terminating on the back. Straps are provided to fasten the sheet ends together at the back and to suspend it from the shoulders. The vest may also be instrumented to function as a transducer itself to detect chest expansion for heart beat or lung volume monitoring.
