Abstract

This study evaluates an Emergency Drive System (E.D.S.) developed by the authors to provide an electrically powered drive system for a disabled arterial pump head.

The methods used in this study were designed to evaluate the E.D.S. under simulated clinical conditions using an American Optical Model 16655 pump with 1/2″ tubing in the arterial pump head and a Sarns 5000 pump with 3/8″ tubing in the arterial pump head. The E.D.S. was applied to the .arterial pump head and was required to produce a six liter per minute flow based on the revolutions per minute of the pump head. The study was deemed successful if the E.D.S. was capable of providing the revolutions per minute for a two hour period.

The E.D.S. was capable of providing the 100 revolutions per minute for American Optical pump and the 230 revolutions per minute for the Sarns 5000 pump, necessary to produce a six liter per minute flow rate.

In conclusion our study shows the E.D.S. is an easy and accurate device for providing temporary power to a disabled arterial pump head.
