    • An improved apparatus for hemodialysis treatment includes an ultrasonic module with an ultrasonic transducer coupled to a membrane or hollow fiber dialyzer. An ultrasonic waveform generator is switchable between various modes, including a narrowband sine wave, a variable or sweeping frequency sine wave and a broadband square or sawtooth waveform. A low power setting is used to increase the diffusion rate across the semipermeable membranes of the dialyzer and a high power setting is used intermittently to break up thrombus that may form within the dialyzer. A chamber downstream of the dialyzer has an ultrasonic or optical emboli detector for detecting thrombi or emboli exiting the dialyzer and a focused ultrasonic transducer to break up any emboli in the chamber. A screen or filter at the exit of the chamber prevents thrombi and emboli larger than a certain size from entering the patient's circulatory system.
    • 用于血液透析治疗的改进装置包括具有耦合到膜或中空纤维透析器的超声波换能器的超声波模块。 超声波波形发生器可在各种​​模式之间切换,包括窄带正弦波,可变或扫频频率正弦波和宽带平方或锯齿波形。 使用低功率设置来增加透析器半透膜上的扩散速率,间歇地使用高功率设置来分解可能在透析器内形成的血栓。 在透析器下游的腔室具有超声或光学栓塞检测器,用于检测离开透析器的血栓或栓塞以及聚焦超声波换能器以分解腔室中的任何栓塞。 在室的出口处的屏幕或过滤器防止大于一定尺寸的血栓和栓塞进入患者的循环系统。
