Abstract

To improve the accuracy of blood pressure measurements, the photocell and light source are mounted within a light transmissible air bag and spherical domes are eliminated from these elements. This makes the occluding surface smoother and eliminates any saline attack on the photocell. This method of mounting also permits the use of a thinner open mesh protecting fabric. Such is because the fabric is no longer required to support the photocell and light source. Additionally, the photocell and light source are mounted so as to be spaced further from each other. This reduces the possibility of either being directly over the artery and greatly improves occlusion efficiency and reduces the need for tension in applying the device. Also, the repeatability of signal amplitudes is thus improved.
