In one embodiment, the analyzer may be used to analyze bodily fluid samples, such as blood, plasma, serum, urine or cerebrospinal fluid, for example. Embodiments of the invention relate to an apparatus and method, for example, an immunoassay method, for separating out target molecules in a magnetic field and then analyzing those target molecules with a luminometer.

Abstract: A fish attracting device including a first rotating member configured to rotate about a first central axis in response to movement of the first rotating member relative to water, the first rotating member having at least one asymmetrical blade protrusion positioned to encourage rotation of the first rotating member relative to the water in response to the movement of the first rotating member relative to the water; and a second rotating member coupled to the first rotating member, the second rotating member being configured to rotate about a second central axis in response to movement of the second rotating member relative to the water, the second rotating member having an asymmetrical blade protrusion positioned to encourage rotation of the second rotating member relative to the water in response to the movement of the second rotating member relative to the water, the rotation of the second rotating member being substantially opposite the rotation of the first rotating member.

Abstract: A clinical instrument analyzer system for automated analysis of patient samples with a system for suspending particles or methods for the separation of particles, such as magnetic particles, is described herein. The system for suspending particles comprises a reagent cartridge comprising a reagent holder for holding a plurality of tubes. The plurality of tubes comprise a mixing tube for holding particles, rotatably mounted in the holder and a motor operatively connectable to a slot longitudinally positioned on the lower section of the mixing tube. The particles in the mixing tube are suspended when the mixing tube rotates in accordance with the embodiments of the invention. The analyzer can be used to analyze bodily fluid samples, such as blood, plasma, serum, urine or cerebrospinal fluid.

Abstract: The invention features an exhalation assist device for adjusting the airway resistance in an exhalation circuit of a medical ventilator. The device includes a set of pressure, airflow and airway sensors, a controlling processor, a user interface, and a ventilatory unit in communication with a medical ventilator. Data relating to pressure within the ventilatory unit and data relating to exhalation airflow, exhalation circuit pressure and exhalation circuit resistance are provided to the controlling processor by the sensors. The controlling processor compares measured and calculated values for airway pressure, airflow, airway resistance and applied negative pressure with desired values that have been entered by a clinician. Based on these calculations, the controlling processor transmits a signal that will change the applied negative pressure applied to the exhalation circuit by the ventilatory unit.

Abstract: Respiratory therapy apparatus is provided with setting elements such as knobs for inputting set values for various parameters. A digital display is provided for showing measured values of operational variables. The set point for each parameter is displayed on the display apparatus along with the measured values only when the knob or setting element for the particular parameter is engaged by the operator's hand.

Abstract: An exhalation valve is disclosed having an inlet, an outlet and a diaphragm movable between closed position covering the inlet and an open position away from the inlet. The valve includes a bias means comprising a sealed chamber containing a gas acting upon the diaphragm and urging the diaphragm to its closed position. An opening means in said sealed chamber conducts a control pressure to chamber to create the bias acting against one side of the diaphragm. The diaphragm comprises a flexible peripheral portion and a semi-rigid plunger. The plunger has a projection adapted to move within a confined space to align the diaphragm and provide damping to its movement. The flexible peripheral portion of the diaphragm has a specially shaped cross-section comprising two attached cantilever sections that reduce the effective resistance to motion between open and closed positions. In the preferred embodiment, the plunger is an insert that fits into and is retained by the flexible peripheral portion.

Abstract: A coaxial breathing circuit is disclosed and which includes an inner tube for supplying fresh gas to a patient, which may contain a vaporized anesthetic for anesthetizing the patient, and a corrugated outer tube for conducting the patient's exhaled gases from the patient. At the patient end, there is allowed a slippage between the inner and outer tubes to provide flexibility of the overall circuit to bending. At the the machine end, the end that is connected to a mahcine supplying the inspiratory gas, a connector provides the means to join the inner and outer tubes to a male coupling or directly to a male fitting on the machine. The corrugated outer tube is joined to the connector and an outlet is provided for the discharge of the exhaled gases. For the coaxial circuit to be operable, the inner tube is sandwiched between the outer diameter of the male coupling and the inner diameter of an opening in the connector.
