Abstract: In the jackbox of the present invention, a number of electrical connectors are releasably connectable to electrical leads carrying electrical signals representative of at least one physiological patient parameter from the patient to patient monitoring equipment. Preferably, the jackbox has an openable enclosure for gaining access to electrical connectors therein. When closed, the enclosure preferably substantially surrounds the electrical connectors and ends of the electrical leads. The enclosure can have a clamshell, book, or other form as desired. Although an openable enclosure is preferred, some embodiments of the jackbox have no enclosure or have an enclosure not permitting user access to the interior thereof. Enclosures according to different embodiments of the present invention are made of resilient and relatively non-deformable, semi-deformable, or deformable material.

Abstract: An inflatable cuff is disclosed for encircling a patient's finger and which includes a light source and a light detector constructed in a way to detect the movement, or lack of movement, of arterial passages within the finger. The cuff is comprised of an inflatable bladder that contacts the patient finger; having a tubing provided for inflation and deflation of the bladder. Surrounding the external surface of the bladder from the finger is a metalized backing that covers and shields the inflatable bladder. A flexible circuit is affixed to the metalized backing and to which is attached the light source and light detector and which further includes wiring from the light detector and light source to a connector at its distal end for connection to further circuiting. Further, surrounding the flexible circuit is a electrical and light shielding and label that covers the flexible circuit and which provides shielding as well as a means of affixing the inflatable cuff to the patients finger.
