摘要： A device for controllably releasing a fluid into an ambient environment. According to a particular embodiment of the present invention, the device comprises a housing having a fluid compartment and an orifice compartment disposed adjacent thereto and in fluid communication therewith via an orifice. The fluid compartment contains the fluid for release to the ambient environment. The orifice compartment includes a fluid exit opening covered by a removable sealing element and contains an initial quantity of fluid when the device is in an inactivated state. A fluid restrictor is disposed adjacent the orifice to restrict fluid flow from the fluid compartment into the orifice compartment in the inactivated state. A gas-generating cell is in selective communication with the fluid compartment such that gas generated by the cell is directed into the fluid compartment when the device is in an activated state. A fluid membrane is disposed between the gas-generating cell and the fluid compartment that allows the gas generated by the cell to pass therethrough to the fluid compartment in the activated state while preventing fluid within the fluid container from passing therethrough to the cell in the inactivated state. The device is activated by removing the sealing element to allow the initial quantity of fluid to exit out of the orifice compartment via the fluid exit opening and activating the cell to generate gas and force fluid from the fluid compartment to the orifice compartment and out the fluid exit opening in a controlled manner.

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： 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： 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.
