We have already consulted with the project lead about the current status and possible design and implementation choices and deadlines. # PROBLEM Taken from the Mobile Phototherapy Unit abstract: "Hyperbilirubinemia is very common, affecting one in two infants globally. If left untreated, it can lead to serious neurodevelopmental problems. While phototherapy is very effective in lowering bilirubin levels, the treatment method leaves much to be desired." Current treatments of phototherapy require an infant to be undressed and placed on something similar to a tanning bed for many hours to a few days. The infant is separated from their parents during this time leading to anxiety on both ends. Uncomfortable protective eyewear to prevent retinal damage to the infant causes more anxiety. The uncontained blue light can also interfere with sleep. # SOLUTION The solution is to treat Hyperbilirubinemia by creating a wearable cloth suit or blanket/cap with blue LEDs that produce 460-490 nm light. This will replace the need to administer phototherapy on the aforementioned apparatus and make it portable. The light sources are placed very close to the skin and will be encased in the suit or blanket/cap. With this solution no protective eyewear is needed and will allow the parents to possibly take the baby home. This solution will have the ability to monitor the color of the baby’s skin to see improvements, data logging to determine usage, and an application for a healthcare provider and parents to see this information and make adjustments. # COMPONENTS ## HARDWARE Power Component: Battery to power suit/blanket will be located on the outside of the suit. This will be rechargeable and will last around 6 hours on a single charge. Sensors: Temperature Sensor: Will need numerous temp sensors in order to monitor the heat within the suit Flex sensor/pressure sensor: Detect if baby is in suit Color Sensor: Sensor to measure color for skin Fault Detection: Detect LED light failure Internal time clock: Log time treatment is used Circuitry/PCB connections: Microcontroller: Will be used to control the LEDs, MCU will be on PCB Wifi Module: Chip to connect to MCU and will connect to software Application where data will be sent Power: Will connect battery to main PCB LED Lights: These lights will connect to the pcb and power and will have the base wavelength of 460-490 nm ## SOFTWARE The main thing for this is to be able to log data. We want to be able to collect the data from sensors through the MCU and into an application. Application: Will likely have to boot an application that communicates with the wifi/Bluetooth module on the suit. Through the application we want to be able to collect different types of data which include things like battery power, the wavelength of light, heat/temperature, is the baby in the suit or not. This will collect data and allow physicians to remotely monitor for proper usage of the suit. # SUCCESS CRITERION Determining the appropriate light wavelength based on skin color detection (only some data showing there may benefit to doing this currently) Create a prototype for either a suit or blanket + cap with LED lights inside Mount all sensors and implement all related functionality with the measured data Data logging would be useful to determine proper usage at home Integrate an appropriate rechargeable battery without putting the infant at risk or compromising the integrity of the unit Healthcare provider should be able to remotely monitor the logged data # CONTINGENCY PLANS If we have our PCB and sensors and suit created we can hand it over to the lead and we focus on the data logging application. Project lead Yusef will be on campus, so we would slash off most of the electronic hardware and focus on the software and data logging. This would be a simple design decision adding more bells and whistles to the software and less to the hardware. |
