<p>An apparatus and method for sensing and measuring penile blood flow wave forms and for evaluation of penile erectile function based on these wave forms is disclosed. Noninvasive sensors such as piezoelectric pulse wave transducers or pulse sensors such as piezoelectric pulse wave transducers or pulse oximetry transducers (103, 105, 107) are attached to the penis and developed electrical signals representing penile blood flow wave forms. These electrical signals are conditioned by a digital signal processor (slave) (401) and a host computer (master) (449) and associated programs. The penile blood flow wave form conditioning includes comparison of the subject's real time penile blood flow wave form with reference penile blood flow wave forms stored in memory to yield the penile erectile function based on penile erection phase, penile blood flow systolic and diastolic velocities, penile intracorporal pressure, penile intracorporal resistance and/or penile blood oxygenation. These values and wave forms are displayed on a monitor and saved on an archive device for future play back.</p> |
