Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 words
A device for the application of medically active substances to animals via the nasal mucosa comprising a pair of opposing medicament carrier members for respectively supporting a medically active substance directly adjacent to and in juxtaposition with the mucosa on opposite sides of the nasal septum of an animal and means for operatively interconnecting said carriers and for supporting the carriers on the nasal septum, said interconnecting means including a pair of spaced generally oppositely directed support arms, said carrier members being respectively mounted opposite to each other on said support arms at right angles thereto whereby said carrier members extend generally coextensive to each other, said support arms and said carrier members being located and dimensioned to space the opposed carrier members slightly apart from one another to receive the nasal septum of an animal therebetween with the opposed portions of said carrier members in direct contact with said nasal septum to apply said medically active substance thereto and to cooperate simultaneously with said interconnecting means to hold said device on said nasal septum.
Claim 2
Independent Claim
175 words
A device for the application of medically active substances to animals via the nasal mucosa comprising a pair of opposing medicament carrier members for respectively supporting a medically active substance directly adjacent to and in juxtaposition with the mucosa on opposite sides of the nasal septum of an animal and means for operatively interconnecting said carriers and for supporting the carriers on the nasal septum, said interconnecting means including a pair of spaced generally oppositely directed support arms, said carrier members being respectively mounted opposite to each other on said support arms at right angles thereto whereby said carrier members extend generally coextensive to each other, said support arms and said carrier members being located and dimensioned to space the opposed carrier members slightly apart from one another to receive the nasal septum of an animal therebetween with the opposed portions of said carrier members in direct contact with said nasal septum to apply said medically active substance thereto and to cooperate simultaneously with said interconnecting means to hold said device on said nasal septum.
Claim 3
Dependent Claim
57 words
A device as defined in claim 1 wherein said carrier members comprise parallely extending disk like enlargements having cavities formed therein opening towards each other and containing said active substance, said enlargements being spaced from each other to receive the nasal septum of an animal therebetween, thereby to apply said substances directly to the animal''s nasal mucosa.
Claim 4
Dependent Claim
90 words
The device as defined in claim 2 wherein said means for interconnecting and supporting said carriers comprises a ring-like member formed of a resilient material operatively connected at opposite ends thereof to said disk-like carrier members, said opposite ends of said ring-like member extending towards each other and defining said oppositely directed support arms, said support arms being relatively straight and in substantially axial alignment whereby said ring forms a clamp with said carrier members to hold said carrier members in position directly against the nasal septum of the animal.
Claim 5
Dependent Claim
16 words
The device as defined in claim 3 wherein said ring-like member has a generally rectangular configuration.
Claim 6
Dependent Claim
63 words
The device as defined in claim 3 wherein said ring-like member extends outside of the nasal passages of said animal when supporting said carrier members on the nasal septum, said ring-like member having an open cavity formed in the portion thereof outside the animal''s nasal passage, said open cavity containing said active substance mounted therein and thereby presented for licking by the animal.
Claim 7
Dependent Claim
24 words
The device as defined in claim 5 including a porous pad of material positioned in each of said cavities and containing said active substance.
Claim 8
Dependent Claim
39 words
The device as definEd in claim 5 wherein an active substance is contained in each of said cavities and a layer of permeable material is positioned over the open end of said cavities for engagement against the nasal septum.
Claim 9
Dependent Claim
15 words
The device as defined in claim 7 wherein said active substance is a galenic preparation.
Claim 10
Dependent Claim
25 words
The device as defined in claim 1 wherein said active substance is selected from the group consisting of gestagens, androgens, oestrogens, antitympanic and antiparasitic agents.
Claim 11
Dependent Claim
55 words
The device as defined in claim 2 wherein said means for interconnecting and supporting said carrier members comprises cooperating male and female connector members respectively formed in said disk-like carrier members, said male member being adapted to pierce the nasal septum and engage said female member to support said carrier members on the nasal septum.
Claim 12
Dependent Claim
13 words
A device as defined in claim 3 wherein said resilient material is plastic.
