Title:
CONTINUOUS BLOOD PURIFYING DEVICE
Document Type and Number:
Japanese Patent JP3186518
Kind Code:
B2
Abstract:
PURPOSE: To reduce burden of managing body fluid balance of a patient to an operator, by providing a volume measuring means for measuring intermittently filtrate flow volume on an exhausting side of a filtrate pump, and controlling rotating speed of the filtrate pump so that the obtained measured value of filtrate is matched with a set value.
CONSTITUTION: Filtrate is flowed into a measuring container 7 when an opening/ closing valve 9 is opened and a filtrate clamp 8 is closed during rotating a filtrate pump 3. The filtrate clamp 8 is opened while the opening/closing valve 9 is opened thereby the filtrate in the measuring container 7 is flowed out when surface of liquid is beyond a lower filtrate level sensor 10a and reaches an upper level sensor 10b. These operations are repeated at a specified interval, and a time necessary for flowing into the measuring container 7 is measured as the time until the liquid surface is beyond the lower filtrate level sensor 10a and reaches the upper filtrate level sensor 10b, the flow volume of the filtrate pump 3 is calculated from this time and the volume of the measuring container 7. The rotating speed of the filtrate pump 3 is controlled so that this filtrate flow volume is matched with the set value.
