Abstract:
A method and apparatus for preventing abrasion on an infant&#39;s nose and adjacent areas when used in conjunction with respiratory administration devices.

Description:
FIELD OF THE INVENTION 
     The following invention is generally related to instrumentalities and methodologies in assisted breathing in infants. More specifically, the instant invention is directed to a method and apparatus for providing a non-abrasive cushioning seal between an assisted breathing device and an infant&#39;s skin. 
     BACKGROUND OF THE INVENTION 
     Babies born prematurely frequently lack the ability to keep their lungs from collapsing. Under normal circumstances, a baby&#39;s lungs will expand during inhalation and only partially contract during exhalation. Premature or newborn babies frequently have weak inspiratory movements causing collapse of the lung after exhalation. Collapse may also occur in the newborn as a result of blockage of bronchioles by mucus or from failure of the lung to distend. 
     As a result, such babies are aided in breathing by an apparatus whose purpose it is to prevent lung collapse. The connection from the respiratory apparatus to the infant is embodied in a nosepiece that is inserted into the baby&#39;s nares to direct the flow of air. Because the premature infant&#39;s skin is delicate, it is susceptible to abrasions and ulcerations from the nosepiece or from other interfaces, such as masks, rendering long-term aid difficult and painful and compounding the baby&#39;s problems. 
     SUMMARY OF THE INVENTION 
     The present invention is distinguishable over the prior art in that abrasion of an infant&#39;s nose is avoided while the infant is receiving assisted breathing support. Preferably, a silicone rubber nostril piece is provided with a foam pad that serves as a buffer between the infant&#39;s skin and the nostril piece. The foam pad has a self-adhesive backing to ensure that the pad remains securely attached to the nostril piece, and is dimensioned to surround the flexible stems that provide the infant with air without blocking airflow. Additionally, the pad provides protection for areas adjacent to the nose. 
     OBJECTS OF THE INVENTION 
     Accordingly, it is a primary object of the present invention to provide a new and novel device and method for assuring that an infant&#39;s nostril piece remains in place as long as necessary. 
     It is a further object of the present invention to provide a device and method as characterized above in which abrasion of the infant&#39;s skin adjacent the nares is avoided. 
     It is a further object of the present invention to provide a device and method as characterized above which is easy to apply and to replace. 
     Viewed from a first vantage point, it is an object of the present invention to provide a device to prevent abrasion on the nose of an infant receiving assisted breathing, comprising, in combination: two nostril-engaging stems, dimensioned to be received within the nares of the infant; and friction-reducing means circumscribing the nostril-engaging stems and abutting the nose of the infant. 
     Viewed from a second vantage point, it is an object of the present invention to provide a nose abrasion kit for an infant including a nostril-engaging member dimensioned to penetrate nares of the infant, and an adhesive-backed foam member dimensioned to overlie the nostril-engaging member and abut against a nose of the infant. 
     Viewed from a third vantage point, it is an object of the present invention to provide a method for reducing nose friction on an infant undergoing respiratory control, the steps including: interposing a low friction pad between an infant nose and a respiratory administering device. 
     These and other objects will be made manifest when considering the following detailed specification when taken in conjunction with the appended drawing figures.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Considering the drawings, wherein like reference numerals denote like parts throughout the various drawing figures, reference numeral  10  as shown in FIG. 4 is directed to the non-abrasive cushioning device according to the present invention. 
     In its essence, the non-abrasive cushioning device  10  is formed by joining a cusion layer  1  with a nostril piece  20 . The cushion layer  1  is formed as a thin sheet of material, preferably low-density polyethylene foam, having a foam side  2  and an adhesive side  4  (FIG.  1 ). The adhesive side  4  is preferably coated with an acrylic adhesive, and formed with a peel-off backing  6 . The cushion layer  1  is equipped with two ports  8  that register with a nostril piece  20 , preferably made of silicone rubber, allowing the nares-receiving stems  22  of the nostril piece  20  to pass through the ports  8 . As show, the ports  8  may be located off-center with respect to the short axis of the cushion layer  1 , to provide additional cushioning to adjacent areas when the non-abrasive cushioning device  10  is assembled. 
     The nostril piece  20  (FIGS.  2 , 3 ) fits an apparatus such as that disclosed in U.S. Pat. No. 5,975,077. Block  24  on a bottom face of the nostril piece  20  includes openings  26  to frictionally override an outer periphery of an air delivery apparatus (not shown) in tight, sealing engagement. A relief  28  extends between the openings  26 , serving to equalize airflow between the nares. 
     A side  12  of the nostril piece  20  opposite the block  24  includes a pair of nares receiving stems  22 , hollow and in fluid communication with the openings  26  and therefore the air delivery apparatus. A ledge  32  of the nostril piece  20  includes a peripheral wall  33  which ensures no air leakage at the connection site. The upper wall  33  of the ledge  32  includes extended ends  34  for removal of the nostril piece from the attached air delivery apparatus. The cushion layer  1  covers the upper surface of the ledge  32 . FIGS. 4-6 show the nostril piece  20  with the cushion layer  1  in place. 
     In use and operation, the backing  6  is removed from the cushion layer  1  and the adhesive side  4  is pressed against the nostril piece  20  such that the two ports  8  overlie the nares-receiving stems  22 . The adhesive side  4  bonds to the side  12  of the nostril piece  20  overlying its entire extent, leaving an overhang  14  of the cushion layer  1  that is in not attached to the nostril piece  20 . The overhang  14  may serve a dual function, providing a convenient surface while installing or removing the cushion layer  1  and protecting skin adjacent to the baby&#39;s nose from abrasion. When the cushion layer  1  contacts areas around the baby&#39;s nostrils, the device  10  rides with the baby during respiratory motion and minimizes frictional abrasion between the nostril piece  20  and the baby. 
     Moreover, having thus described the invention, it should be apparent that numerous structural modifications and adaptations may be resorted to without departing from the scope and fair meaning of the instant invention as set forth hereinabove and as described hereinbelow by the claims.
