医用便携式智能恒温箱的设计与实现OA

Objective To design a medical portable intelligent incubator to meet the demand for new types of medical portable intelligent incubator in the medical field.Methods The incubator body was built with acrylic sheets,and the temperature inside the incubator body was collected in real time through the DS18B20 temperature sensor.The collected temperature was input into the STC89C52 single-chip microcomputer controller,and the self-designed fuzzy proportion integration differentiation(PID)controller was used for operation.The output temperature control drive circuit HIP4082 full-bridge drive chip drived the H bridge,and the TEC1-12706 semiconductor refrigeration sheet temperature control element was used to control the temperature of the incubator.Results The medical portable intelligent incubator designed in this study could achieve precise temperature adjustment.Physical tests showed that when the set temperatures were 25.0℃and 50.1℃,the temperature in the incubator at 30 min were(25.0±0.1)℃and(50.1±0.1)℃respectively.The design and construction of a portable incubator with a temperature control range of(4.0±0.2)to(48.0±0.2)℃was achieved.Conclusion The medical portable intelligent incubator designed in this study can meet clinical needs and has certain clinical promotion value.
