A closed system device for diagnosis and evaluation of neonatal pneumothoraces

A closed system device with teflon needle, sideholes, and attached stopcock was designed and evaluated for diagnosis and evacuation of neonatal pneumothoraces. Experience with this device has demonstrated specific advantages over existing needles and techniques. Since the system is airtight, diagnosis of pneumothorax can be performed without the risk of introducing air. In addition, the needle sideholes provide more complete and efficient evacuation of air and fluids from the pleural cavity.
