摘要： An apparatus and method for treating sleep apnea includes a bilevel flow generator having an alternating current (AC) synchronous motor coupled to a low inertia centrifugal rotor/impeller. The process of acceleration and deceleration of the rotor involves moving from frequency A, amplitude A to frequency B, amplitude B in an optimal linear fashion using the so-called Bresenham algorithm. This is coupled with a tuned increase of the amplitude during the acceleration process which will produce the acceleration using minimum current allowing the use of smaller power supplies. During deceleration the process is accomplished in reverse fashion using a tuned decrease of the amplitude coupled with a special shunt circuit to prevent power supply voltage changes. These changes in amplitude overlay a current feedback mechanism used to prevent loss of synchronization of the motor by changing amplitude. Speed changes can also be timed so as to prevent desynchronization.
摘要翻译：一种用于治疗睡眠呼吸暂停的装置和方法包括具有耦合到低惯性离心转子/叶轮的交流（AC）同步电动机的二级流量发生器。转子的加速和减速过程包括使用所谓的Bresenham算法以最佳线性方式从频率A，振幅A到频率B，幅度B移动。这与在加速过程中调节振幅的增加相结合，这将使用允许使用较小电源的最小电流产生加速度。在减速过程中，使用与特殊分流电路耦合的振幅的调谐减小来反向完成该过程，以防止电源电压变化。幅度上的这些变化覆盖了电流反馈机制，用于通过改变振幅来防止电动机的同步损失。速度变化也可以定时，以防止失步。

摘要： A system for reprocessing and sterilizing a previously used catheter having at least one lumen is disclosed. The catheter is provided with a housing and enclosed within the housing. Heated sterilant is provided to the housing and the catheter. The lumen is tested during the reprocessing and sterilizing cycle for blockages and integrity. If the catheter is of a type having a balloon tip, the balloon is also tested for integrity by inflating and deflating it a plurality of times. The housing is pressurized to a level above the ambient pressure and maintained at such pressure whereby the sterility of the catheter is maintained for up to one week. Further disclosed is an apparatus for selectively coupling used catheters to a source of sterilant. The apparatus includes a housing having a tray for holding the catheter in place during reprocessing, a door for enclosing and locking the catheter within the housing, and a plurality of valves for coupling the housing to a source of sterilant. In addition, the apparatus includes a cap for maintaining the sterility of the catheter during storage.

摘要： A piston assembly includes a cross-head piston and a cylindrical cross pin. The cross-head piston includes a piston head having a cylindrical wall, a lateral surface and an opposite inward surface. Two spaced-apart connection ears, each having a proximal end and an opposite distal end, extend outwardly from the inward surface. Each proximal end is affixed to the inward surface and each distal end defines a pin bore passing therethrough. A piston well is defined by the inward surface and the connection ears. The cylindrical cross pin is disposed coaxially with a central axis so as to be engaged with both pin bores. The cross pin defines a central cross pin oil passage passing transversely to the central axis. The cross pin is placed in relation to the piston head so that the second end of the cross pin oil passage is directed to the piston well.
