CRRT displacement fluid formula calculator

The utility model discloses a CRRT (Continuous Renal Replacement Therapy) displacement fluid formula calculator which comprises a casing, an input unit, an output unit, an internal unit and a power supply unit, wherein the input unit comprises a calculator keyboard and an information prompt LCD (Liquid Crystal Display) lamp which are arranged on the casing; the output unit comprises an LCD and a USB (Universal Serial Bus) communication interface unit; and the LCD is embedded into the casing and used for displaying operational data. With the calculator, the ion concentrations of all ingredients of CRRT displacement fluid can be quickly and accurately calculated, and the influence degree of the displacement fluid on all electrolytes and the PH value of blood in the therapeutic process can be predicted; and meanwhile, the variation values of the electrolytes and the PH value of the blood are predicted per hour. A reference and an optimal treatment scheme are provided for the clinic therapy of continuous blood pu
