Abstract

Abstract An artificial breast is disclosed which is made up of two approximately similar but differently sized plastic bags, one disposed inside the other. The inner bag is filled with a liquid substance adapted to impart to its wearer the feeling of the weight of a natural breast. The outer bag is inflated by air blown into the space between the inner and the outer bag through a flap valve which is part of the outer bag. Inflating serves for adjusting the size and shape of the artificial breast to the size and shape of the remaining natural breast.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 181 words
An artificial breast comprising an external air-filled bag (2) of plastic material and an internal liquid filled bag (7), said internal bag (7) being completely separate from said external bag (2), said internal bag (7) being freely disposed within said external bag (2) when said external bag (2) is airfilled, said external bag (2) having an air valve (10), arranged at an edge (5) thereof, said air valve (10) having an inlet opening (11) terminating in the interspace (8) between said external bag (2) and said internal bag (7) in two superposed flaps (12, 13), said flaps (12, 13) being connected, in the area of the inlet opening (11) at the margins thereof (11a, 11b), together with the edge (5) of said external bag (2) to form an airtight seal, said flaps (12, 13) having a substantially triangular shape and extending with the triangular apex within the interspace (8) between the two bags (2, 7) underlying said internal bag on the under side of that portion (17) of said internal bag (7) extending in the direction of the air valve (10).
Claim 2
Dependent Claim 181 words
An artificial breast comprising an external air-filled bag (2) of plastic material and an internal liquid filled bag (7), said internal bag (7) being completely separate from said external bag (2), said internal bag (7) being freely disposed within said external bag (2) when said external bag (2) is airfilled, said external bag (2) having an air valve (10), arranged at an edge (5) thereof, said air valve (10) having an inlet opening (11) terminating in the interspace (8) between said external bag (2) and said internal bag (7) in two superposed flaps (12, 13), said flaps (12, 13) being connected, in the area of the inlet opening (11) at the margins thereof (11a, 11b), together with the edge (5) of said external bag (2) to form an airtight seal, said flaps (12, 13) having a substantially triangular shape and extending with the triangular apex within the interspace (8) between the two bags (2, 7) underlying said internal bag on the under side of that portion (17) of said internal bag (7) extending in the direction of the air valve (10).
Claim 3
Dependent Claim 69 words
An artificial breast according to claim 3, characterized in that the outer surface of the external bag (2) is provided with at least one compensating fold (20) extending at right angles to the longitudinal axis (15) of the device (1) in the zone of the inlet opening thereof, as seen from the air valve (10), said fold comprising a linear indentation found in the surface of the external bag.
Claim 4
Dependent Claim 57 words
An artificial breast according to claim 1, wherein the device has an approximately oval shape and exhibits a stronger initial curvature (18) in the breast region and a flatter terminating end (17); and wherein the air valve (10) is arranged on the narrow oval side (9), so that the terminating end (17) faces the air valve (10).
