Abstract

Abstract A model of human female breast for teaching breast examination comprises an opaque, elastomeric membrane simulating skin, a transparent backing member connected to the opaque membrane to define a chamber therebetween, first means simulating adipose tissue disposed in the chamber, at least one second means simulating a tumor within the chamber and opaquing means overlying and being removably attached to the transparent backing member. In addition, the present invention is directed to a method of training a person to detect breast tumors by palpating said model.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 65 words
A model of a human female breast for teaching breast examination, comprising an opaque, elastomeric membrane simulating skin, a transparent backing member connected to the opaque membrane to define a chamber therebetween, first means simulating adipose tissue disposed in the chamber, at least one second means simulating a tumor within the chamber and opaquing means overlying and being removably attached to the transparent backing member.
Claim 2
Dependent Claim 65 words
A model of a human female breast for teaching breast examination, comprising an opaque, elastomeric membrane simulating skin, a transparent backing member connected to the opaque membrane to define a chamber therebetween, first means simulating adipose tissue disposed in the chamber, at least one second means simulating a tumor within the chamber and opaquing means overlying and being removably attached to the transparent backing member.
Claim 3
Dependent Claim 15 words
The model according to claim 1, wherein the transparent backing member is an elastomeric membrane.
Claim 4
Dependent Claim 22 words
The model according to claim 1, wherein the opaquing means comprises an opaque, pliable sheet material adhesively attached to the backing member.
Claim 5
Dependent Claim 22 words
The model according to claim 3, wherein the sheet material is a textile fabric coated with an adhesive on one side thereof.
Claim 6
Dependent Claim 44 words
The model according to claim 1, further comprising third means simulating glandular, connective and/or skeletal tissue being disposed in the chamber and adjacent the backing member, the third means being harder than the first means and having an irregular surface adjacent the first means.
Claim 7
Dependent Claim 20 words
The model according to claim 5, wherein the third means is disposed adjacent only a portion of the backing member.
Claim 8
Dependent Claim 54 words
The model according to claim 6, wherein a first indicating means is disposed on the opaque membrane overlying a portion of the chamber containing only the first and second means, and a second indicating means is disposed on the opaque membrane overlying a portion of the chamber containing the first, second and third means.
Claim 9
Dependent Claim 23 words
The model according to claim 7, wherein the first and second indicating means are raised from the external surface of the opaque membrane.
Claim 10
Dependent Claim 22 words
The model according to claim 5, wherein a plurality of second means of different sizes and hardnesses is disposed in the chamber.
Claim 11
Dependent Claim 22 words
The model according to claim 9, wherein at least one second means is attached to the irregular surface of the third means.
Claim 12
Dependent Claim 23 words
The model according to claim 1, wherein a plurality of second means of different sizes and different hardnesses is disposed in the chamber.
Claim 13
Dependent Claim 18 words
The model according to claim 11, wherein at least one second means is attached to the opaque membrane.
Claim 14
Dependent Claim 18 words
The model according to claim 11, wherein at least one second means is attached to the backing member.
Claim 15
Dependent Claim 19 words
The model according to claim 11, wherein at least one second means is disposed freely within the first means.
Claim 16
Dependent Claim 25 words
The model according to claim 11, wherein at least one second means is attached to a layer of elastomeric resin polymer fixed within the chamber.
Claim 17
Dependent Claim 14 words
The model according to claim 1, wherein the second means comprises sponged silicone rubber.
Claim 18
Independent Claim 135 words
A method of training a person to detect breast tumors by palpating a model of a human female breast having at least one simulated tumor disposed therein, said model having an opaque, elastomeric membrane simulating skin, and a transparent backing member providing means for visually inspecting the presence and location of a simulated tumor, comprising: (1) overlying and removably attaching opaquing means to the transparent backing member of the model; (2) palpating the model in a predetermined pattern to create a tactile sensation in the person as to the presence and location of a simulated tumor; (3) removing the opaquing means; (4) visually inspecting the model to visually determine the presence and location of a simulated tumor; and (5) palpating the model to confirm the presence and location of a simulated tumor by tactile sensation.
Claim 19
Independent Claim 135 words
A method of training a person to detect breast tumors by palpating a model of a human female breast having at least one simulated tumor disposed therein, said model having an opaque, elastomeric membrane simulating skin, and a transparent backing member providing means for visually inspecting the presence and location of a simulated tumor, comprising: (1) overlying and removably attaching opaquing means to the transparent backing member of the model; (2) palpating the model in a predetermined pattern to create a tactile sensation in the person as to the presence and location of a simulated tumor; (3) removing the opaquing means; (4) visually inspecting the model to visually determine the presence and location of a simulated tumor; and (5) palpating the model to confirm the presence and location of a simulated tumor by tactile sensation.
Claim 20
Dependent Claim 30 words
The method according to claim 17, wherein the opaquing means comprises an opaque, pliable sheet material and method step (1) comprises adhesively attaching the opaquing means to the backing member.
Claim 21
Dependent Claim 22 words
The method according to claim 18, wherein the sheet material is a textile fabric coated with an adhesive on one side thereof.
