    摘要： Apparatus and methods to treat skin defects include a pump with reservoirs for a pressurization gas and a fluid, the fluid loaded at a factory and sealed or filled at point of use through a valve, septum, or the like. Upon activation, the pump generates a gas introduced into the gas reservoir, a movable wall of which displaces a movable wall of a fluid source, thus dispensing the fluid into the dressing to spread throughout irrespective of orientation of the dressing, maintaining a transport fluid (e.g. carrier) in the dressing and in contact with a skin defect being treated. Delivery may be periodic, constant, programmatically controlled, or manual. A dressing may maintain intimate contact, a transport fluid, and a controllable concentration of active ingredient against a skin defect.Apparatus and methods to replenish a dressing with a therapeutically effective concentration of a fluid deliver a fluid carrier containing an active ingredient. The fluid may be stored in and delivered from a pump mechanism including reservoirs for a pressurization gas and the fluid, which may be loaded at a factory and sealed or filled at point of use through a valve, septum, or the like. The dressing may have a distribution network, and multiple members, dispensing the fluid into a wick maintaining a transport fluid (e.g. carrier) distributed in the dressing and in contact with a skin defect being treated. Delivery may be periodic, constant, programmatically controlled, or manual to maintain intimate contact, a transport fluid, and a controllable concentration of active ingredient against wounded tissue.

    摘要： An apparatus 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 apparatus features steady rate performance without refreshing the water chamber and low temperature sensitivity.
