<p>An inflatable cuff (l0) is disclosed for encircling a patient's finger and which includes a light source (38) and a light detector (40) constructed in a way to detect the movement, or lack of movement, of arterial passages within the finger. The cuff (l0) is comprised of an inflatable bladder (l2) that contacts the patient finger; having a tubing (24) provided for inflation and deflation of the bladder (l2). Surrounding the external surface of the bladder from the finger is a metalized backing that covers and shields the inflatable bladder (l2). A flexible circuit (l6) is affixed to the metalized backing (l4) and to which is attached the light source (38) and light detector (40) and which further includes wiring (42, 46) from the light detector (40) and light source (38) to a connector (54) at its distal end for connection to further circuiting. Further, surrounding the flexible circuit (l6) is a electrical and light shielding and label (l8) that covers the flexible circuit (l6) and which provides shielding as well as a means of affixing the inflatable cuff (l0) to the patients finger. The overall cuff (l0) is readily manufacturable and particularly adapted for its specialized use.</p> |
