Benefits of technology

This patented technology describes various technical features related to improving the performance of medical devices such as kidneydiazers used during hemodialyzer treatments. By continuously delivering new fluid through the system while keeping track of its usage throughout the procedure helps prevent errors caused by insufficient empty volumes being delivered due to lack of spare parts. Additionally, there may include other functions like priming operations where the replacement solution needs to be added beforehand, allowing for precise addition without any residual material left behind. Overall, these improvements improve the efficiency and accuracy of the reninsechanger function in hemodiafilters.

Problems solved by technology

This patented technical problem addressed in this patents relates to monitoring the amount of urine remaining within different parts of the system before and during medical procedures involving dialytic treatments like HD and HFD. Existing methods involve manual measurement of residual fluids on scales attached to the part being treated, leading to potential overfill issues due to excessive amounts of liquor entering the disposable components themselves.

Abstract

The present invention relates to a blood purification device comprising a discharge liquid subdivision chamber for pooling a discharge liquid being discharged from a blood purification apparatus purifying blood of a patient, a first discharge liquid discharge line for causing the discharge liquid to flow through to the discharge liquid subdivision chamber, a second discharge liquid discharge line for causing the discharge liquid pooled by the discharge liquid subdivision chamber to be discharged to the exterior of the device, a discharge unit disposed on the second discharge liquid discharge line for discharging the discharge liquid pooled by the discharge liquid subdivision chamber to the exterior of the device, a residual amount detection unit for detecting the residual amount of the discharge liquid pooled by the discharge liquid subdivision chamber, a determination unit for determining, on the basis of the detection result from the residual amount detection unit, whether or not the discharge liquid amount in the discharge liquid subdivision chamber has reached a reference residual amount, and a control unit for controlling the discharge unit, wherein the control unit controls the discharge unit to execute a discharging step of discharging the discharge liquid pooled by discharge liquid subdivision chamber to the exterior of the device, and end the discharging step when the determination unit determines that the discharge liquid amount in the discharge liquid subdivision chamber has reached the reference residual amount.
