Measuring apparatus for the non-invasive detection of venous and arterial blood flow and drainage disorders |
摘要 |
A measuring apparatus for the quantitative evalution of peripheral venous drainage disorders and arterial blood flow disorder in man. In clinical practice, this invention makes it possible on the one hand to objectively detect the changes in cutaneous circulation under physical strain, while it can also be employed, on the other hand, to detect obstacles to venous flow in the extremities. The measuring apparatus detects peripheral drainage and blood flow disorders in human extremities which makes it possible to detect by measuring technology the evacuation and filling of dermal vessels-veins and arteries-non-invasively, objectively and quantitatively. The measuring apparatus comprises a plurality of sources of radiation directed on to the skin of the area of the respective extremity, a radiation receiver for measuring the amount of radiation reflected or dispersed back by the cutaneous vascular plexus, a temperature sensor for simultaneously measuring the skin temperature and an electronic evaluation circuit for detecting and recording the progress of the reflected or dispersed amount of radiation and the skin temperature as a function of time.
