Abstract: Embodiments are directed to methods and apparatuses for ensuring that mechanisms that are used to position components of an apheresis machine are not broken as a result of rotation of a centrifuge. In embodiments, a safety mechanism is provided that contacts components of the centrifuge and pushes them into a position to ensure that they do not break when the centrifuge is operated at high rpm.

Abstract: A system for the continuous monitoring of wear and/or pressure within a gravity concentrator/centrifugal separator [10] is disclosed. The system may comprise a gravity concentrator/centrifugal separator [10] having a cone [30], rotor housing shell [20], and water jacket [40]. At least one detector [34] may be provided to at least one of the cone [30], rotor housing shell [20], and water jacket [40]. At least one integrated or handheld sensor [60] may be provided adjacent to portions of the gravity concentrator/centrifugal separator [10], the sensor [60] being configured to communicate (e.g., wirelessly) with the at least one detector [34] during operation of the gravity concentrator/centrifugal separator [10]. In use, the cone [30] may wear away and ultimately affect a function of the least one detector [34]. In use, pressure changes within the water jacket [40] may change and ultimately affect a function (e.g., an output signal) of the least one detector [34]. The at least one sensor [60] may be configured to monitor said function(s) of the least one detector [34]. When the at least one sensor [60] detects a change in the signal of the at least one detector [34], an operator or control system may be notified that maintenance or cone [30] replacement may be necessary; and/or an operator or control system may be notified that one or more operational inputs may need to be adjusted to obtain peak performance of the gravity concentrator/centrifugal separator [10].

Abstract: A rotor is mounted in a stationary casing of a centrifugal separator. An electrical rotation sensor with a first electric coil mounted on the rotor and a second electric coil, connectable to a power source and mounted on the casing, is provided. A processor associated with the second coil detects voltage oscillation induced in the second coil when the rotor rotates to calculate and display rotor speed. The first coil is connected in a circuit including electrodes exposed to the interior of the rotor at a predetermined position. The voltage across the second coil changes when the electrodes are contacted by accumulated material in the interior of the rotor. This change is detected to provide an indication that cleaning of the rotor is required. A permanent magnet is mounted on the rotor and causes automatic charging of the battery via the stator coil when the rotor rotates.

Abstract: A continuous flow centrifuge system is provided. The system includes a rotor, a stator, a stator housing, upper and lower bearing plates, upper and lower bearings, first and second snap rings, and lip seal. The upper bearing rotatably secures a shaft of the rotor in the upper bearing plate. The first snap ring secures the upper bearing to the rotor shaft. The lip seal is over the upper bearing and forms a rotatable seal with the upper bearing plate. The second snap ring secures the lip seal to an inner diameter of the upper bearing plate. The upper and lower bearing plates are secured to the stator housing so that the rotor is operatively aligned with the stator.
