초록 ▼

A microprocessor controlled transdermal medication patch system wherein said medication is dispensed internally by positive displacement from multiple reservoirs within said patch so as to vary the drug selection, sequence, and concentration and thereby the regimen and release rate. In a preferred embodiment, electric resistance heating elements activate multiple heat-shrink polymer reservoirs to dispence beneficial fluids into a common absorbent layer for transdermal passage.

대표청구항 ▼

A microprocessor controlled transdermal medication patch comprising: a micro-processor controller circuit; a battery power source connected to the micro-processor controller to supply electrical power; user control means connected to the micro-processor controller to enable users to activate or deactivate the transdermal medication patch; sensing means connected to said micro-processor controller for sensing physiological variables in the body; connection means for connecting said micro-processor controller circuit to a disposable patch, the patch comprising of: (1) a top seal layer; (2) a plurality of segregated reservoirs containing a plurality of beneficial fluids; (3) at least one common reservoir; (4) a semi-permeable membrane; (5) an adhesive layer for attachment to the skin; and (6) a removable layer to protect said membrane and said adhesive layer prior to use; wherein the improvement comprises the addition of positive displacement dispensing means to each of said segregated reservoirs so as to make said patch capable of microprocessor controlled selection for dispensing from among said plurality of beneficial fluids into said common reservoir internal to said patch.
