Abstract
A system includes a pump, an inlet sensor, an outlet sensor, and a controller. The pump is configured for pumping fluid in a phacoemulsification system. The inlet sensor is coupled with an inlet port of the pump and is configured to sense an inlet temperature of the fluid at the inlet port. The outlet sensor is coupled with an outlet port of the pump and is configured to sense an outlet temperature of the fluid at the outlet port. The controller is configured to take a responsive action based a difference between the inlet temperature and the outlet temperature crossing a defined threshold.
Claims20
A system, comprising:
- a pump for pumping fluid in a phacoemulsification system;
- an inlet sensor, which is coupled with an inlet port of the pump and is configured to sense an inlet temperature of the fluid at the inlet port;
- an outlet sensor, which is coupled with an outlet port of the pump and is configured to sense an outlet temperature of the fluid at the outlet port;
- and
- a controller configured to take a responsive action based on a difference between the inlet temperature and the outlet temperature crossing a defined threshold.
A method, comprising:
- sensing an inlet temperature of a fluid at an inlet port of a pump for pumping fluid in a phacoemulsification system;
- sensing an outlet temperature of the fluid at a respective outlet port of the pump;
- and
- detecting a temperature of the pump based on readings of the inlet and the outlet temperatures, and taking a responsive action based on a difference between the inlet temperature and the outlet temperature crossing a defined threshold.
