Abstract: A medication ointment applicator comprising a length of plastic film to which is attached a backing band made of a length of elastic mesh material. The ointment is applied to the surface of the plastic film which is engaged with the skin of the user, the elastic material backing band being wrapped around, for example, the user's ankle or wrist such as to hold the plastic film in firm engagement with the skin for absorption of the medication ointment through the skin. Preferably, the plastic film is provided with a scale enabling the user to measure the correct amount of ointment to be applied as a result of measuring the length of a ribbon of ointment expelled from a dispenser tube, and the surface of the plastic film to which the ointment is applied is textured, in one embodiment of the invention, by ridges being formed on the surface, to help contain the ointment within the edges of the plastic film.

Abstract: The release pattern of a dispersion type active agent dispenser can be improved by forming the device from a depleted zone containing the agent at a concentration no greater than the saturation and a non-depleted zone containing the agent dispersed in the matrix at a uniform concentration greater than saturation. The depleted zone is disposed between the surface through which the agent is to be dispensed and at least a substantial portion of the non-depleted zone with the interface therebetween disposed at a non-uniform distance from the releasing surface. Certain embodiments are particularly useful for the transdermal administration of drugs.

Abstract: A therapeutic device adapted to releasibly confine a quantity of therapeutic material therefrom to a recipient or environment of use and comprises a supporting member, means disposed in the supporting member to receive a therapeutic material, means for detecting when a predetermined amount of therapeutic material has been deposited within the receiving means and means for securing the device adjacent to the recipient or environment of use. The means for receiving the therapeutic material may comprise according to the invention a chamber, channels, or capsules. The means for detecting when a predetermined amount of therapeutic material has been deposited comprises indicia of measurement such as lines and numerals and spaced ridges or raised portions, the spaces between each of which represent a quantity of measurement. Attaching members are provided for securing the device and the therapeutic material adjacent the recipient and/or environment of use.
