A Solid State Surgical Monitor for Veterinary Medicine.

A concept for an apparatus which provides audio and visual monitoring of the heart function is developed, including circuitry to give indications of abnormal conditions. The machine is intended for use during surgery by doctors of veterinary medicine, but also may have some application for monitoring of human patients. System design and principles applied to realize a physical prototype of this concept are presented. The complete electronic and mechanical design plus fabrication of the surgical monitor is described in detail. Schematic diagrams of all electronic circuitry employed and photographs of the prototype equipment are included, along with a set of operating instructions for non technically trained personnel.
