The reservoir is generally non permeable to the drug, but has a membrane, or plate, of defined surface area through which said drug can pass. In use, this membrane or plate is held against the patient's skin to allow the drug to be absorbed. The device further includes cooperating locking mechanisms for detachably securing the reservoir on the strap or band whereby the supply of drug can be replenished by removing the spent reservoir and inserting a fresh one containing a new supply of the drug.Field of SearchBandage, pad, or shield placed on body for sustained treatment thereofBandage, pad, shield, or attaching means extendable around body portion Sudatory devices (e.g., removing sweat, etc.) With piston or plunger for expelling material therefrom Material impelled into body by contraction of expanded elastic material reservoir Material exhausted from body by expansion of contracted elastic receptacle or resilient means therein Material impelled by spring Spring drives piston Spring triggered by skin contacting means Specific structure of means coupling piston to piston actuator Mechanical means (e.g., piston, clamp, etc.) moved to collapse reservoir | |
