AUTOMATIC MEASURING AND DISCHARGING DEVICE FOR ULTRAFILTRATION LIQUID UTILIZING NEGATIVE PRESSURE TYPE BED SIDE CONSOLE

PURPOSE:To improve operability by allowing a motor to make one turn every time a specific amount of ultrafiltration liquid is stored in a cylinder part and discharging the ultrafiltration liquid automatically, and displaying the discharge of the ultrafiltration liquid digitally. CONSTITUTION:A water level measuring sensor 19 is fitted to the lower end of the hollow part 10 of a hollow piston 9 inserted into the cylinder part 16 of a liquid storage container 8, and this water level measuring sensor 19 is arranged below a liquid port 13 formed in the side wall of the cylinder part 16. Every time a specific amount of the ultrafiltration liquid 19 is stored in the cylinder part 16, an electric circuit 23 among the ultrafiltration liquid 18, water level measuring sensor 19, and motor 20 is closed and the motor 20 makes one turn. Consequently, the ultrafiltration liquid 18 in the cylinder part 16 is discharged automatically and the discharge of the ultrafiltration liquid during ultrafiltration is calculated from the discharge of the ultrafiltration liquid 18 and the rotating speed of the motor 20 and displayed digitally.
