Abstract
Abstract A device for oral administration to a ruminant animal includes a veterinary medicament, such as an anthelmintic, uniformly dispersed throughout an erodable sheet 1 comprising an ethylene-vinylacetate copolymer. The sheet 1 is rolled up and stuck together with adhesive backed paper strips 3 for administration, and unrolls in the rumen to take up a planar configuration which is retained in the rumen. The sheet may be placed within a plastics netting envelope 11 to give more controlled erosion and release of medicament.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
57 words
A device for oral administration to a ruminant animal, comprising a veterinary medicament dispersed uniformly throughout a carrier sheet, characterised in that the carrier sheet is erodable and the device is designed to be constrained into a first shape which allows oral administration and to assume in the rumen a second shape whereby it is retained therein.
Claim 2
Independent Claim
57 words
A device for oral administration to a ruminant animal, comprising a veterinary medicament dispersed uniformly throughout a carrier sheet, characterised in that the carrier sheet is erodable and the device is designed to be constrained into a first shape which allows oral administration and to assume in the rumen a second shape whereby it is retained therein.
Claim 3
Dependent Claim
16 words
A device according to claim 1, characterised in that the erodable sheet comprises an erodable polymer.
Claim 4
Dependent Claim
15 words
A device according to claim 2, characterised in that the polymer comprises an ethylene-vinylacetate copolymer.
Claim 5
Independent Claim
41 words
A device according to any one of the preceding claims, characterised in that the erodable sheet is flexible to permit folding or rolling of the sheet into the first shape, and unfolding or unrolling of the sheet into the second shape.
Claim 6
Independent Claim
19 words
A device according to any one of the preceding claims, characterised in that the veterinary medicament is an anthelmintic.
Claim 7
Independent Claim
25 words
A device according to any one of the preceding claims, characterised in that the medicament represents from 15 to 40% by weight of the sheet.
Claim 8
Independent Claim
26 words
A device according to any one of the preceding claims, characterised in that the erodable sheet is attached to or surrounded by a resilient support member.
Claim 9
Dependent Claim
25 words
A device according to claim 7, characterised in that the support member comprises a sheet of resilient water insoluble polymer attached to the erodable sheet.
Claim 10
Dependent Claim
23 words
A device according to claim 7, characterised in that the support member comprises an apertured, flexible envelope or bag containing the erodable sheet.
Claim 11
Dependent Claim
19 words
A device according to claim 9, characterised in that the bag or envelope is constructed of plastics netting material.
