Claims11
A pressure sensitive adhesive film for securing a medical device on human skin, comprising:
- a base layer in the form of a laminate, one layer of which is formed of a polyolefin and another layer of which is formed of a mixture of a polyolefin and an ethylene-vinyl ester copolymer;
- and a layer of a water base coated pressure sensitive adhesive on the surface of the layer of said laminate which is formed of said copolymer, said water base coated pressure sensitive adhesive layer consisting essentially of a mixture of a water-insoluble polyacylic latex and a water-insoluble ester resin, and being characterized in that it is water and perspiration resistant and inert with respect to drugs or medicaments with which it may come into contact with while securing a medical device on human skin, and further being characterized in that it is non-irritating to the human skin.
In a transdermal delivery system which includes an element for carrying a drug or medicament adapted to be absorbed into the body through the human skin, the improvement which comprises as a component of said system:
- a film in the form of a laminate, one layer of which is formed of a polyolefin and another layer of which is formed of a mixture of a polyolefin and an ethylene-vinyl ester copolymer;
- and a layer of a water based coated pressure sensitive adhesive on the surface of the layer of said film which is formed of said copolymer, said pressure sensitive adhesive layer consisting essentially of a mixture of a water-insoluble polyacrylic latex and a water-insoluble ester resin, and being characterized in that it is water and perspiration resistant and substantially inert with respect to the drug or medicament carried by said element, and, further, in that it is non-irritating to the human skin.
