A parameter calibration instrument for blood purification device

which can simultaneously detect multi-path parameter is developed.The instrument includes a loop

which connects to blood purification device

and sensors are in the loop in series

so that while the dialysis is flowing through this loop

sensors can acquire data of various parameters.In order to realize convenience of detection and carring

the circuit part is designed using integrated modularization design based on MSP430 low-power consumption microcontrollers

high-performance and small-packaged components are used to establish a modular

high-precision

multi-functional

portable system.The uncertainty of conductivity is 0.04 mS/cm

uncertainty of temperature is ± 0.1 ℃

uncertainty of pressure is ±0.05 kPa

the uncertainty of flow is±20 mL/min

the uncertainty of the pH values is ±0.02.
