ABSTRACT:
A muscle powered liquid dispensing insert is provided for use with an implanted anchor having a hollow anchor sleeve extending into the subcutaneous fascia of a region behind an animal's ear. The insert includes one or more balloon-like reservoirs, each containing a drug or other medicant in substantially liquid form. Each reservoir means additionally provides effective means for anchoring the insert in the animal. A pump assembly draws the medicant(s) from the reservoir(s), and dispenses such to the animal. The pump assembly has a toroidal pump body defining a pump chamber and including a flexible impermeable pump diaphragm. The pump chamber communicates through inlet check valve means with each of the reservoirs, and through outlet check valve means with the tissue of the animal. The outlet check valve means operate at a higher activation pressure than the inlet check valve means. A piston powered solely by the animal's muscle and tissue operates the pump diaphragm. One or more tubes communicating through the interior of the anchor sleeve between an associated reservoir and a self-sealing opening allow the reservoirs to be refilled. A cap and plug seal the anchor sleeve against the entry of contaminants and other foreign material, and support the self-sealing ends of the tubes. The plug can be removed to allow the insert to be removed from the anchor by means of a suitable tool.
