    摘要: An apparatus for detecting movement in patients coupled to pulse oximeters and a method for using the signal generated by the apparatus to filter out the effects of motion from the test results generated by the pulse oximeter are disclosed. In a preferred embodiment, a piezoelectric film located in close proximity to the pulse oximeter's sensor provides a voltage signal whenever movement occurs near the sensor. This voltage signal is processed and the resulting signal is used to correct the oximeter's measurements. In addition to piezoelectric film, accelerometers and strain gauges are also usable to provide a signal indicative of motion.

    摘要: Described are embodiments of a canister, system, and method of filtering fat. Embodiments include a sidewall that defines a volume, a filter with a screen, a first port, a second port, and at least one vane which allows for manual agitation of lipoaspirate within the volume. The first port is used to draw fluid from below the filter, forcing excess fluid in the lipoaspirate to be quickly extracted. The vane allows the lipoaspirate to be repeatedly drawn over the filter to aide in removing of liquids from fat in the lipoaspirate. The treated fat may then be removed from the volume through an outlet port and reinjected into a patient.
