    • A plethysmograph is provided with a sensor for detecting an increase or decrease in the blood volume of a vascular bed, preferably by photoelectrically detecting blood content in a finger-apex position. The detection signals derived from the sensor are twice or triply differentiated to produce an acceleration curve indicative of blood circulation whose interpretation effectively leads to a diagnosis of the entire circulatory system including early signs of malfunction. Detection of the presymptoms of arteriosclerosis, myocardial infarction, cerebral apoplexy, subarachnoidal hemorrhage, etc. is possible and the apparatus may be used to monitor the patient's condition during subsequent treatment. A visual or printed card of the diagnostic results can be provided.
    • 具有用于检测血管床的血容积的增加或减少的传感器,优选通过光电检测手指顶点位置的血液含量的体积描记器。 从传感器得到的检测信号是两次或三次分化,以产生指示血液循环的加速曲线,其解释有效地导致包括早期的故障迹象在内的整个循环系统的诊断。 动脉硬化,心肌梗死,脑中风,蛛网膜下腔出血等症状的检测是可能的,并且该装置可用于在随后的治疗期间监测患者的状况。 可以提供诊断结果的视觉或打印卡。
