1. A surgical tourniquet controller, said controller comprising:
- a flow control unit, said flow control unit comprising at least one pressure control valve and a flow control unit communications interface; and
a remote unit, said remote unit for controlling the at least one valve for controlling pressure, said remote unit comprising an input interface and a remote unit communications interface;
a surgical tourniquet pressure sensor, said pressure sensor for sensing pressures in a surgical tourniquet cuff; and
a flow control processor, said flow control processor controlling the at last one pressure control valve in accordance with a pressure profile, said pressure profile comprising at least one parameter defining an operating condition of a surgical tourniquet, said at least one parameter selected from a group of parameters consisting of duration, desired pressure, and maximum allowable pressure;
wherein said input interface is able to accept entry of said at least one parameter, and wherein said remote unit communications interface is communicably connected to said flow control unit communications interface via at least one communications path, and further wherein said remote unit communications interface is capable of communicating said at least one parameter from the remote unit to the flow control processor via the at least one communications path.

Abstract
The present invention is a surgical tourniquet controller which receives operational parameters from a remote unit, allowing flow components associated with controlling a surgical tourniquet to be collocated with a surgical tourniquet in use, while allowing an operator of the tourniquet to operate the flow components from a remote location, such as at an anesthesiologists position, thus reducing the involvement of the surgical tourniquet operator from the surgical field.
