Abstract
An intra-ruminal device of a Laby-style design that includes a cap having a sidewall and top, the cap located over the barrel opening and including an outlet in the top; and a variable geometry device defined by at least one pair of resilient wings extending outwardly from the end of the body distal to the first end, each pair of wings having a pair of reinforcement ridge that extend a first distance from the body along the wing surface, and at least one middle reinforcement ridge that extends between the pair of ridges from the body a second distance, and where the second distance is less than the first distance.
Claims22
An intra-ruminal device, comprising:
- an elongate body or body assembly substantially impervious to rumen fluids, the body defining a barrel having a first end and a second end, and an opening at the first end,
- at least one variable geometry device connected to and extending from the body at the second end to assist rumen retention,
- a dose of an active agent within the body to be accessible to rumen fluid via the first end,
- a biasing arrangement within the body adapted to bias a plunger against the active agent in the barrel towards the first end, and
- a cap located over the opening at the first end and comprising an outlet in the top,
- wherein the variable geometry device is defined by at least one pair of resilient wings extending outwardly from the second end of the body, each pair of wings having at least a first reinforcement ridge that extends a first distance from the body along a surface of the wing, and at least a second reinforcement ridge that extends a second distance, and where the second distance is less than the first distance, and wherein each pair of wings comprise a cushioning zone at a distal end of the wing that is thicker at least partially around the perimeter of the cushioning zone.
