![]() Baby chamber maintained 24oC as normal room temperature and when enabled forĥ0mins raised to 37OC ☑ at humidity of 75% to 86%. Second power regulating circuit has transformer enables voltage regulator 7812Īnd 7085, bridge diode, 10k resistors and 2200μf capacitor that convert 220v to 12v supply to microcontroller, Such that power supply to the entire system is from national grid or 100w, 220v solar cell inverter viaġ2v ac step-down transformer. The circuits were designed and simulated on proteus 8 and printed on breadboards Condiment drawers were partitions immediately beneathĬhamber mattresses of 2cm thick. Two compartments for heat exchange control andĮlectrical components circuitry were at the base. Triplet baby incubator was designed and constructed to accommodate closed-loop stable thermal environmentĪnd control unit with perpex alumaco board of density tensile strenght1200kgm2 for cabin chambers of perimeterĪrea 120x50x46cm structured with 2mm sliding doors. Conventional designed incubatorįor triplet infants are rare due to consequences of operation failure, infants’ death and heavy litigation. Temperature sustenance that demand critical nursery care specialized machinery. Preterm triplets are predisposes to low weight, respiratory problems, infections and difficulty body There are increased risk of complicationsĪssociated with pre-term care and greater are obvious with triplets gestational period of less than 37 Pre-term infant care is an important and very sensitive specialty in medicine. It can be used commercially in the hospitals as too at home. At the same time the incubator is free of health hazard. The system can control the temperature at the set level of 36 o C to 37 o C and relative humidity at the set level of 70% to 75%. The salient features of the model are – it is entirely microcontroller based, can be locally developed at a low cost and is a sophisticated version of conventional incubator systems. A flowchart is provided to illustrate the logical expression of the program. For implementation, a software program has been developed in C which comprises a code editor. The control system components include relative sensors, fans, bulbs, heater and Arduino Uno microcontroller. Smaller compartment consists of temperature and humidity control unit and larger compartment consists of a mattress where the baby is kept. The chamber has two compartments larger and smaller. A neonatal incubator has been designed, modeled and developed which is incorporated with embedded temperature and humidity control system.
