  • Patent number: 4252128
    Abstract: A Visual Pulse Indicator, which may be placed directly over any area of the human body where an artery is near the surface of the skin, and includes the use of a transparent plate member, a flexible membrane and a fluid emulsion located between them. A peripheral member may also be located between the transparent member and the flexible membrane for further efficient containment of the fluid emulsion. The visual pulse indicator may be placed upon a person with the flexible membrane nearest the skin in the vicinity of any convenient pressure point such as that found in the wrist or the temple. The expansion of an artery, while absorbing a part of the pressure of the heart ventricles may be felt, and it is known as the pulse. This expansion produces movement of the artery, the skin, and even the flexible membrane of the Visual Pulse Indicator when in proper position.
