Abstract

An oxygen humidification and delivery device includes a case, humidification material, a seal film or seal plate, and an oxygen delivery tube. The humidification material is disposed within the case. At least two protuberant air ports are provided on the top of the case, one of which is air inlet, and the other is air outlet. The seal film or seal plate is adapted to seal the case accommodating the humidification material. The air ports are connected to the oxygen delivery tube.
