An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing and a mounting structure. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by placement in the mounting structure. However, unless force is applied to keep the occluder mechanism in the mounting structure, the occluder will move relative to the mounting structure and return to the first, closed position.

A sensor and method of use provides for detection of an occlusion (or sudden pressure increase) in tubing during the administration of solutions to a patient. The occlusion sensor may be attached to an infusion pump using a biasing mechanism. The tubing may be positioned in contact with the occlusion sensor using a cassette. Detection of an occlusion in the tubing is accomplished by measuring the compression and expansion of the tubing. When the tubing becomes occluded pressure within the tube will increase, resulting in expansion of the tubing. Expansion of the tubing exerts a force on the sensor to trigger an alarm to alert medical personnel of the occluded tube.

Current phacoemulsification handpieces require rigorous cleaning after each procedure because the aspiration and irrigation pathways for fluids are integral to the handpiece. According to the present invention, a removable horn extension and nosecone may be used with a phacoemulsification handpiece to allow for disposable fluid pathways exterior to the handpiece. This will reduce the cleaning time and effort, reduce cross-contamination, and increase the lifespan of the handpiece. Furthermore, the current invention allows different horn extensions to be used to excite different motions at the tip of the handpiece, depending on the preference of the surgeon.

A Langevin transducer horn uses split electroding or selective electroding of transducer elements and phase relationships of the voltages applied thereto to determine the relative longitudinal and flexural/transverse motion induced in the tip of the horn.

An apparatus and method for preventing free flow through an infusion set utilizes an occluder disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. The occluder may also be configured to allow flow when the infusion set adjacent the occluder is moved sideways relative to the occluder or maintained at an angle relative to the occluder. When a pair of occluders are used in sequence, an in-line pump may be formed.
