Abstract
A fluid management system with a detection circuit for detecting whether an attached surgical device is operational. The fluid management system changes at least one operation mode when the surgical device is detected as being operational. The fluid management system may include inflow, outflow, or inflow/outflow capabilities, and monitors at least one signal characteristic of an AC power signal provided to the surgical device.
Claims30
A fluid management system comprising:
- an interface for a power cord of a surgical device;
- a detection circuit to monitor at least one signal characteristic of an AC power signal provided to the surgical device, said detection circuit configured to signal when said surgical device changes from a non-operational state to an operational state;
- and
- a pump control circuit configured to receive said signal from said detection circuit and change at least one operation mode of said fluid management system.
A method of operating a fluid management system comprising:
- detecting a change in at least one signal characteristic of an AC signal being supplied to a power cord of an attached surgical device;
- and
- when said change is detected, switching at least one operation mode of said fluid management system.
A device for controlling a direction of a fluid path of a fluid management system, said mechanism comprising:
- a rotating motor;
- and
- a wheel attached to the rotating motor to restrict a first tube of said fluid path when said rotating motor rotates to one of a first and second position and a second tube of said fluid path when said rotating motor rotates to the other of said first and second positions,
- wherein said rotating motor is configured to rotate to a third position during replacement of said first and second tubes.
