Abstract

Device for introducing drugs and the like into the human body by infusion through the skin, consisting of a fluid delivery tube leading to a storage and distribution chamber means that is attached to a porous sheet which is in contact with the skin.

Claims

1. Transdermal infusion device, comprising:

(a) an impervious main sheet formed of a foamed polymer plastic,

(b) a manifold sheet attached to one side of the main sheet and providing a passage complex in the form of a screen made up of strands of a polymer plastic,

(c) a flexible fluid delivery tube extending through the main sheet and into the passage complex of the manifold sheet,

(d) a porous sheet formed of gauze attached to and coextensive with the manifold sheet and adapted to lie against a human skin to release fluid thereto,

(e) an annular adhesive layer in a peripheral area provided on the said one side of the main sheet and completely surrounding both the manifold sheet and the porous sheet, and

(f) a release sheet overlying the adhesive peripheral area of the main sheet, as well as the porous sheet and the manifold sheet.

2. Transdermal infusion device, comprising:

(a) an impervious main sheet,

(b) a manifold sheet attached to one side of the main sheet and providing a passage complex,

(c) a flexible fluid delivery tube extending through the main sheet and into the passage complex of the manifold sheet, the outer end of the delivery tube being provided with a luer connector,

(d) a porous sheet attached to and coextensive with the manifold sheet and adapted to lie against a human skin to release fluid thereto,

4. Transdermal infusion device as recited in claim 2, wherein the manifold sheet consists of a woven screen and the passage complex consists of spaces defined by the strands forming the screen.

3. (e) an annular adhesive layer in a peripheral area provided on the said one side of the main sheet and completely surrounding both the manifold sheet and the porous sheet, and

(f) a release sheet overlying the adhesive peripheral area of the main sheet, as well as the porous sheet and the manifold sheet.
