Abstract

A configuration register is incorporated into an electrically powered tourniquet apparatus for enabling an operator to change the values of parameters initially employed at the time of the next use of the apparatus, such as the initial pressure settings and elapsed time omits.
These changed initial values of parameters are stored in memory and remain there despite inadvertent or intentional interruption of electrical power to the apparatus. An event register provides capability for recording the occurrence of events (cuff inflation, cuff deflation, etc.) and for relating the occurrence of the events to hazards and undesirable outcomes such as nerve damage associated with tourniquet usage. A
safety circuit is included to detect and respond safely to certain failures which are possible within the tourniquet apparatus.
