    摘要: A controlled delivery device for holding and administering a biologically active agent includes a housing having a first end portion, a second end portion, and a port associated with the housing. Enclosed within the housing is a displacing member, a chemical or electrochemical gas generating cell, activation and control circuitry. The electrochemical or chemical cell generates gas within the housing, forcing the displacing member against the beneficial agents contained within the housing and forcing the beneficial agents through an outlet port and into an animal's body cavity at a predetermined rate. An anchoring mechanism may be associated with the housing for securing the housing inside the body cavity of the animal being treated. Also disclosed are methods of delivering the beneficial agents into the animal's body cavity using the delivery device of the present invention.

    摘要: A fluid delivery apparatus includes a housing having an open end and an interior surface. The interior of the housing defines a cavity within the housing. The cavity, in combination with a piston-like member, defines a reservoir for containing a fluid (e.g. such as an aromatic or other solvent or a solvent in which has been dissolved an aromatic substance). The piston has a port, and fits in piston-like arrangement within a cylinder contained within the housing. The piston moves within the housing, and movement of the piston acts to displace fluid from the port upon contraction of the reservoir (e.g. when the annular piston is driven into the device). Preferably, a fluid tight membrane covers the housing's open end. The apparatus also preferably further includes a conduit to transport fluid from the housing of the reservoir. The conduit has, on a first end, an exterior circumference sized and shaped to interact with the port of the annular member. On the second end of the conduit is preferably associated a sponge, wick or equivalent fragrance dispenser.

    摘要: A method for delivering a beneficial agent is disclosed in one embodiment of the invention as including a water collection chamber. A water-transporting membrane is provided to communicate with the water collection chamber. An extraction chamber receives water through the water-transporting membrane, expanding the extraction chamber. A dispensing chamber, containing a beneficial agent, is configured to contract upon expanding the extraction chamber. This causes the dispensing chamber to expel the beneficial agent through a subterranean delivery channel, such as a rigid hollow spike. In certain embodiments, a rate adjustment mechanism may control the rate that water is received through the water-transporting membrane, thereby controlling the rate the beneficial agent is expelled. The water-transporting membrane has features that repel osmagent from passing through to the water collection chamber. The method features steady rate performance without refreshing the water chamber and low temperature sensitivity.

    摘要: An apparatus for delivering a beneficial agent to a subterranean location is disclosed in one embodiment of the invention as including a water collection chamber having a substantially open end. A water-transporting membrane is provided to communicate with the water collection chamber. An extraction chamber receives water through the water-transporting membrane, expanding the extraction chamber. A dispensing chamber, containing a beneficial agent such as fertilizer, is configured to contract upon expanding the extraction chamber. This causes the dispensing chamber to expel the beneficial agent through a subterranean delivery channel, such as a rigid hollow spike. In certain embodiments, a rate adjustment mechanism may control the rate that water is received through the water-transporting membrane, thereby controlling the rate the beneficial agent is expelled from the subterranean delivery channel.

    摘要: An apparatus for providing controlled delivery of a beneficial agent is disclosed. In one embodiment, such an apparatus includes a water chamber and a filter to produce filtered water by removing impurities from water introduced into the water chamber. A water-transporting membrane transports filtered water from the water chamber to an extraction chamber, thereby expanding the extraction chamber. The extraction chamber contains an osmagent that provides the driving force to pull the filtered water through the water-transporting membrane. As the extraction chamber expands, a dispensing chamber containing a beneficial agent contracts. This causes the beneficial agent to be expelled through a port in communication with the dispensing chamber. A corresponding method is also disclosed.
