Non-Invasive Neonatal Vital Acquisition Unit Michael Bunalski, Biomedical Engineering Melissa Mastro, Biomedical Engineering Advisor: Dr. Brett BuSha, Biomedical Engineering
Background • Premature infants neonates born prior to 37 weeks of gestation • Most organ systems have not fully developed • Apnea/problems breathing due to immature lungs or pneumonia • Lower muscle and activity compared to full-term infants • Problems feeding due to difficulty sucking or coordinating swallowing and breathing • Less body fat • Thin, smooth, shiny skin, which is often transparent (can see veins under skin)
The Problem Infants will have contact electrodes across skin, Often causes Abrasions Tears Future scarring
Our Proposal • We propose the development of a smart vest for neonates with non-adhesive electrodes to collect vital biosignals, eliminating the need for potentially skin damaging adhesive.
Design Considerations • Over all construction • Full jacket design small jacket • Cloth neoprene • Back vs. Front ECG acquisition • Lead/Pad Design • Gold • Non contact • Self triangle design- non adhesive conductive gel • Conductive gel/pad replaceable vs. triangle unit
Sensors Commonly Used • Pulse Oximetry (SpO2) • Able to be placed around babies wrist ankle toe or hand • Chosen wrist/hand for ease of wiring • Respiratory Rate Band • Babies are stomach breathers therefore band goes around stomach • Cannot be to tight to prevent or slow breathing • Temperature sensor • Not needed for most babies • Slot will be made on the vest for sensor to go into
Testing and Validation Due to the nature of our project, all testing must occur on adults. The vest will be designed on the macro-scale and then scaled down to fit neonates between 500 g and 4.5 kg.
Social Impact Considerations • Parents must find the device appealing to the eye • With less wires the babies will look more “human” • Hospitals with a agenda in personal comfort will look a lot better to society • Compilation of wire • Many wires that will be coming off/one bulky wire • Wireless would greatly increase overall aesthetics and mobility
Health and Safety Considerations • Vest cannot cause any stress on breathing • Cannot cause any allergic reactions • No abrasions caused • Vest needs to be small • Nurses and physician need to see as much of the baby as possible • Stomach much be visible to diagnose gastro issues
Other Considerations • Economic • similar materials to that which is being used currently • addition of silicone to normally used product • Sustainability • silicone is a durable substance • neoprene durable substance-machine washable • Manufacturability • silicone is easily mass produced • molded very well
