Apparatus for delivering a continuous positive airway pressure to an infant
First Claim
1. An apparatus for delivering a continuous positive airway pressure to the nasal passages of an infant weighing between 500 grams and 4500 grams, comprising:
- a) a cannula having a deformable body for sealably engaging a nose of an infant, said cannula including two short, deformable outlets extending outwardly from the deformable body in parallel spaced-apart relationship;
b) means for providing communication between the deformable body of said cannula and a source of positive air flow; and
c) means for securing said cannula to an infant, whereby the deformable outlets of said cannula are inserted into the nasal passages with only incidental contact between the outlets and the nasal passages, said securing means for positioning the deformable body of said cannula to both occlude the nasal passages and deliver a positive airway pressure through the outlets to the nasal passages of an infant.

Abstract
A method of and apparatus for delivering a continuous positive airway pressure to an infant by the use of a light-weight, flexible nasal cannula. The nasal cannula is connected to a source of positive air flow by a pair of flexible hoses. The soft nasal outlets of the cannula reduce damage to the nasal passages of an infant when the outlets are being inserted. The pliable body of the cannula is formed to occlude the nasal passages and prevent leakage. The flexible hoses are gently secured to the cheeks of the infant. The infant can rest in a variety of positions and the medical staff has easy access to the infant.

2. An apparatus for delivering a continuous positive airway pressure to the nasal passages of an infant weighing between 500 grams and 4500 grams, comprising:
-
a) a cannula having a deformable body for sealably engaging a nose of an infant, said cannula including two short, deformable nasal outlets extending outwardly from the deformable body in parallel spaced-apart relationship; b) two flexible air hoses connected to the deformable body of said cannula in the region of the head of the infant and extending to a source of positive air flow; c) a fitting for facilitating fluid communication between said hoses and the source of positive air flow;
securing means for positioning the deformable body of said cannula to both occlude the nasal passages and deliver a positive airway pressure through the outlets to the nasal passages of an infant, said securing means further comprising a slidable clasp and a piece of taped) said slidable clasp encircling said air hoses for positioning and securing the air hoses about the head of the infant; and e) said piece of tape attached to one of the hoses for securing the hose and said cannula to the infant whereby the deformable outlets are inserted into the nasal passages with only incidental contact between the outlets and the nasal passages.
