摘要： A hand-held centrifuge apparatus for sedimenting a fluid suspension in a sample tube, the sample tube being subjected to centrifugation at an acute angle to the axis of rotation. An electronic circuit activates an electric motor for a preselected time period as a function of voltage supplied by a battery to the motor to provide a predetermined degree of centrifugation to the sample. A voltage tester periodically tests the voltage in the circuit to assure that adequate voltage is being supplied by the battery. A deactivation circuit is actuated if inadequate voltage is sensed and a disabling circuit disables the electronic circuit until adequate voltage is again available. The disabling circuit is masked during acceleration to preclude deactivating the circuit when the motor is in acceleration.

摘要： An artificial sphincter apparatus and method, the artificial sphincter including a pair of parallel, coaxially mounted rings with at least one ring rotatable relative to the other ring. A plurality of tie members mounted circumferentially to the rings extend between the rings and are angularly moved relative to the axis of the artificial sphincter upon relative rotation between the rings so as to selectively occlude or open a bowel engaged by the artificial sphincter. An actuator mechanism mounted on the artificial sphincter permits the artificial sphincter to be operated externally even when the artificial sphincter is implanted.

摘要翻译： 一种人造括约肌装置和方法，所述人造括约肌包括一对平行的，同轴安装的环，其中至少一个环可相对于另一个环旋转。 围绕环周向安装的多个连接构件在环之间延伸，并且在环之间相对旋转时相对于人造括约肌的轴线成角度地移动，以便选择性地闭塞或打开由人造括约肌接合的肠。 安装在人造括约肌上的致动器机构允许人造括约肌在外部操作，即使当人造括约肌被植入时。
