Abstract：To reduce the incidence of iatrogenic anemia, an iatrogenic blood loss monitoring and analysis system for premature
infants was designed. This system included data acquisition, transmission and analysis modules. The amount of blood collected by
ultrasonic liquid level detector was measured by the data acquisition module. Then the basic information of children was read by
electronic label reader. After processing of the microprocessor, the data were transmitted to the monitoring analysis module through
the wireless network GSM. In the following, the data of blood capacity taken, specimen type, hemoglobin valuea and so on were
analyzed by the monitoring analysis module, which could provide references for the timing of doctor prescribed blood collection
and the nurse’s planned blood capacity taken. The system had a large data storage platform and supported data analysis and storage
in several hospitals. The test results showed that the system’s ultrasonic liquid level detection resolution was 0.01 mL, measuring range
was 4.5 cm, accuracy was within ±0.2%, the sound beam width was 5 cm, network transmission speed was 2 MB/s and database storage
was greater than 1 T. The system can provide a new treatment program for patients with anemia risk due to the iatrogenic blood loss.
