Continuous Negative Extrathoracic Pressure for Neonate

In an effort to reduce the incidence of treatment related complications in newborns with Respiratory Distress Syndrome and increase ease of use, we have designed a device to administer continuous negative extrathoracic pressure to newborns with Respiratory Distress Syndrome weighing over 1000g. Our design allows for easy placement over the anterior region of an infant’s chest. By utilizing negative pressure, the device will take advantage of reductions in incidences of treatment related complications shown in literature. The device continuously provides a negative pressure of up to 15cm H2O, in 1cm increments, over the targeted area. The negative pressure is transmitted to the lungs and will increase the infant’s residual capacity, allowing the neonate to breathe naturally. To maximize ease of operation while maintaining efficacy of treatment, the device was designed with three parts: a semi-rigid body, a seal, and a strap. A semi-rigid dome over the thoracic area provides for a cavity capable of holding the necessary negative pressure. The seal seeks to minimize pressure leaks. Finally, a semi-rigid strap will hold the device in place and minimize downward force of the device on the sensitive skin of the infant. We are in the process of testing the device on newborn porcine sample.
