  • Infusion fluid container support
    Patent number: 6969032
    Abstract: Apparatus and methods for use in ophthalmic surgery in which a container for fluid is connected to a line through which fluid flows to a surgical handpiece for the irrigation of a patient's eye are provided. A sensor emits a magnetic field and a detector causes another magnetic field to be generated. The interaction of the two magnetic fields causes a pulse to be generated. Based on the timing of the generated pulse, the apparatus or method determines the absolute position of the support coupled to the container and adjusts the height of the support. Circuitry is also provided to prevent changes in height of the support by preventing supply of drive currents and by applying a hold current or by generating an electro motive force.
