Abstract:
Objective:To develop a remote monitoring system for blood counting and temperature of banked blood in the transfusion department based on 2.4G wireless transmission technique with STM32 single-chip,so as to implement remotely dynamic monitoring for counting and temperature of banked blood in transfusion department.Methods:Based on 2.4G wireless transmission technique with STM32 single-chip,the NRF24L01 wireless transceiver was adopted in this design.STM32 single-chip was used as the processor,and QT50 infrared photoelectric sensor was used to sense the counting for stored blood,and LM35DT temperature sensor was used to collect temperature.The display screen adopted high-brightness digital tube of light emitting diode(LED)of Quanhai(QH)series,so as to achieve accurate data transmission and dynamic monitoring for temperature.Results:The measurement for multiple rooms indoors showed that the distance of wireless transmission can reach 45m without delay,and the counting for banked blood was accurate,and the range of controlling temperature was±0.24℃,which controlled precision was higher than that(±1℃)of national standard.It has ultra-high sensitivity for high and low alarm temperature,which buzzer will alarm when the temperature rises to 7℃or falls to 1℃,and the action time was less than 1s.Conclusion:The developed remote monitoring system for blood counting and temperature of banked blood in transfusion department is flexible in use,and it has stable performance,which can timely prevent the occurrence of blood damage,and greatly reduce the workload of transfusion department.It has a broad application prospect.
