Abstract
Abstract A device for administering a therapeutic or nutrient substance to a ruminant over an extended period of time, comprising at least one body portion containing or comprising said substance and having a first configuration or being adapted to be arranged in a first configuration, whereby it is adapted to be administered per os so as to pass into the rumen and being adapted to change in the rumen into a second configuration which will prevent or at least hinder regurgitation of the device, whereby the device is retained in the rumen. The device is especially useful in the treatment of bovine bloat by extended release in the rumen of surface active substances.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
214 words
A device for insertion into the rumen of a ruminant through the esophagus and adapted to be retained within the rumen for free movement therein over an extended period of time, said device comprising a body containing an effective amount of a therapeutic or nutrient substance of a type normally administered to a ruminant per os, a major proportion of said body consisting of said substance, said body having a compressed configuration and an expanded configuration, the compressed configuration permitting the passage of the device through the esophagus into the rumen and the expanded configuration being one which will substantially retard passage of the device through the esophagus but will still permit substantially free movement of the device within the rumen, means for resiliently urging said body from said compressed configuration to said expanded configuration, restraining means dissolvable in the rumen holding said body in said compressed configuration until it is received within the rumen whereby said device in compressed configuration may be administered per os so as to pass into the rumen and will expand in the rumen so as to hinder regurgitation during the period of treatment, and means for holding said substance in said body and for slowly releasing said substance from said body when said body is in the rumen.

Claim 13
Independent Claim
189 words
A method for the administration of a therapeutic or nutrient substance to a ruminant over an extended period of time comprising incorporating said substance in a device from which it is releasable in the rumen of a ruminant, said device having a first configuration in which it is held by restraining means and a second configuration into which it is resiliently urged, said restraining means being rendered ineffective in and by the rumen environment to hold said device in the first configuration in the rumen, the first configuration permitting passage of the container into the rumen through the esophagus of the ruminant and the second configuration being one which will hinder passage of the container from the rumen but will still permit substantially free movement of the container within the rumen, holding said container in said first configuration by said restraining means and administering it to the ruminant per os so as to pass into the rumen where the restraining means is rendered ineffective to hold the device in the first configuration and the device assumes the second configuration for retention in the rumen during the period of treatment.
