Abstract
A connector for resuscitating an infant or neonate is disclosed. The pressure is varied between Peak Inspiratory Pressure (PIP) and Peak End Expiratory Pressure (PEEP) by the occlusion of the PEEP outlet. The PEEP outlet may either allow variable PEEP, by adjustment, or substantially flow independent fixed PEEP using a novel umbrella valve. A duck billed valve is included for suctioning of surfactant delivery during resuscitation. The connector is adapted to one handed use.
Claims7
A device for use with a breathing assistance apparatus which in use conveys gases to a neonatal infant requiring resuscitation or breathing assistance, comprising:
- a housing, having an inlet and a first outlet, said inlet adapted to be in fluid communication with a breathing assistance apparatus and said first outlet adapted to be in fluid communication with said infant,
- said housing also including an aperture adapted to allow a surfactant delivery tube to be introduced and removed through said aperture, said device adapted so that said delivery tube can deliver surfactant to a patient while said breathing assistance apparatus provides resuscitation breathing assistance,
- said aperture including a seal adapted to prevent gas flow through said aperture in use,
- said housing further including a second outlet that is adapted to act as a venting aperture, and a pressure relief valve located in the flow path between said inlet and said second outlet,
- said second outlet and said housing mutually adapted so that in use a user can hold said housing in position with one hand, and occlude and un-occlude said second outlet with one finger of said one hand to vary the pressure at said first outlet between PIP with said second outlet occluded and all the flow of gases from said inlet passing through said first outlet, and PEEP with said second outlet unoccluded, and a portion of said flow of gases from said inlet passing through said second outlet.
