Abstract
Abstract A pediatric medication inhaler is provided for cooperation with a medication dispersing cylinder and a supply of medication. The inhaler is a one piece device in the nature of a mask molded of integral plastic or elastomer. The invention is characterized in having a bubble or relatively thin wall projecting from the mask-like device, which bubbler flexes inwardly upon inhalation so that a person providing medication to the infant can watch for inhalation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
A pediatric medication inhaler comprising an integral mask-like device molded of flexible plastic material or the like having a central through-opening and including a first portion adapted to grip a cylinder in which medication is dispersed, a second portion of shallow taper and extending from said first portion, a third frusto-conical portion of substantially greater taper extending from said second portion and adapted to fit snugly against an infant's face covering the mouth and nose, said third portion having an integral wedge-shaped outward extension for accommodating the infant's nose, an outwardly projecting bubble integral with said second portion, said second portion having a wall of predetermined thickness and said bubble having a wall that is substantially thinner than the predetermined thickness of said wall of said second portion for enhanced flexibility, whereby said bubble flexes inwardly upon inhalation by said infant for visual observation by an attendant of such inhalation.
Claim 2
Dependent Claim
150 words
A pediatric medication inhaler comprising an integral mask-like device molded of flexible plastic material or the like having a central through-opening and including a first portion adapted to grip a cylinder in which medication is dispersed, a second portion of shallow taper and extending from said first portion, a third frusto-conical portion of substantially greater taper extending from said second portion and adapted to fit snugly against an infant's face covering the mouth and nose, said third portion having an integral wedge-shaped outward extension for accommodating the infant's nose, an outwardly projecting bubble integral with said second portion, said second portion having a wall of predetermined thickness and said bubble having a wall that is substantially thinner than the predetermined thickness of said wall of said second portion for enhanced flexibility, whereby said bubble flexes inwardly upon inhalation by said infant for visual observation by an attendant of such inhalation.
Claim 3
Dependent Claim
18 words
A pediatric medication inhaler as set forth in claim 1 wherein said bubble extends onto said third portion.
Claim 4
Dependent Claim
53 words
A pediatric medication inhaler as set forth in claim 2 wherein said third portion has a wall of set thickness, and further including a rim adjacent the edge of said bubble joining said bubble to said third portion and of greater thickness than said third portion wall for enhanced rigidity at that location.
Claim 5
Dependent Claim
35 words
A pediatric medication inhaler as set forth in claim 2 wherein said inhaler has an axial length, said bubble being axially elongated and having a rounded nose at the end thereof on said second portion.
Claim 6
Dependent Claim
59 words
A pediatric medication inhaler as set forth in claim 1 wherein said third portion has a wall of preset thickness and adapted to conform to an infant's face, and the wedge-shaped extension is of lesser thickness than said third portion wall thickness for further enhanced flexibility for conforming to an infant's nose and the adjacent portion of its face.
Claim 7
Dependent Claim
35 words
A pediatric medication inhaler as set forth in claim 1 wherein the said first portion has a wall of thickness greater than said predetermined thickness for enhanced dimensional stability for gripping a medication dispersing cylinder.
Claim 8
Dependent Claim
20 words
A pediatric medication inhaler as set forth in claim 1 wherein the inhaler comprises a one-piece molding of silicone rubber.
