    Abstract: 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.

    Abstract: An automatic safety occluder provides an occluder for an infusion set that is biased in a closed position until an electrical signal is received that causes the occluder to open. Should the occluder fail to be installed correctly, or if power is removed, the occluder will return to its biased closed position, preventing free flow. The occluder may also be placed in an integrated unit such that the automatic safety occluder may attach to the tubing as a unit.

    Abstract: 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.

    Abstract: A disposable, integrated extracorporeal blood circuit employed during cardiopulmonary bypass surgery performs gas exchange, heat transfer, and microemboli filtering functions in a way as to conserve volume, to reduce setup and change out times, to eliminate a venous blood reservoir, and to substantially reduce blood-air interface. Blood from the patient or prime solution is routed through an air removal device that is equipped with air sensors for detection of air. An active air removal controller removes detected air from blood in the air removal device. A disposable circuit support module is used to mount the components of the disposable, integrated extracorporeal blood circuit in close proximity and in a desirable spatial relationship to optimize priming and use of the disposable, integrated extracorporeal blood circuit. A reusable circuit holder supports the disposable circuit support module in relation to a prime solution source, the active air removal controller and other components.
