Abstract
Abstract A lightweight inflatable patient drape including a pair of opposed impermeable sheets secured together to form an interior cavity which is divided into longitudinal chambers. The body of the drape also has a pair of opposed projecting yoke or neck members adapted to fit around the neck of the wearer and is provided with a valve for inflation purposes. Due to the existence of the longitudinal compartments, upon inflation the device will automatically adopt a curved configuration in cross section compatible with the curvature of the patient''s body thereby minimizing contact with the body of the patient and permitting better air circulation and comfort. Due to the cushioning effect of the air pockets or compartments, greater patient protection is also provided against sharp or heavy dental instruments that are commonly exchanged or carried over the body of the patient during dental operations. In addition, an adhesive layer may be coated to the outside surfaces of the drape to attach neck bands or towels of a disposable nature. A modified form is also disclosed wherein the drape is either filled with lightweight foam material, such as styrofoam, or entirely molded of such material thereby avoiding the need for inflation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
112 words
An inflatable protective patient drape, comprising; A. a pair of impermeable membranes secured together at their peripheries to form an air-tight chamber; B. means for introducing air into said chamber; C. said membranes being secured to each other at transversely spaced intervals to divide said chamber into a plurality of longitudinally extending compartments 1. whereby said drape assumes a curved cross sectional configuration upon inflation and; D. said membranes each having a pair of opposed, integral inflatable neck-engaging members at one end, with said neckengaging members being arcuate in planar and cross-sectional configuration and substantially encircling the patient''s neck 1. whereby said members will support the head and neck of said patient.
Claim 2
Dependent Claim
112 words
An inflatable protective patient drape, comprising; A. a pair of impermeable membranes secured together at their peripheries to form an air-tight chamber; B. means for introducing air into said chamber; C. said membranes being secured to each other at transversely spaced intervals to divide said chamber into a plurality of longitudinally extending compartments 1. whereby said drape assumes a curved cross sectional configuration upon inflation and; D. said membranes each having a pair of opposed, integral inflatable neck-engaging members at one end, with said neckengaging members being arcuate in planar and cross-sectional configuration and substantially encircling the patient''s neck 1. whereby said members will support the head and neck of said patient.
Claim 3
Dependent Claim
28 words
The drape of claim 1 further characterized by the presence of adhesive means on the outer surface of one of said membranes adjacent one end of said drape.
Claim 4

Claim 5
Dependent Claim
24 words
The drape of claim 1 further characterized by the presence of attachment means secured to the outer surface of at least one said membrane.
Claim 6
Dependent Claim
95 words
A protective patient drape, comprising; A. a pair of sheets secured together at their peripheries to form a substantially closed chamber; B. said sheets being secured to each other at transversely spaced intervals to divide said chamber into a plurality of longitudinally extending compartments; and C. a quantity of lightweight foam material being received in and substantially filling said compartments; D. said sheets each having a pair of opposed foam-filled neck-engaging members having an arcuate planar and cross-sectional configuration and substantially encircling the neck of the patient and projecting from one end of said drape
Claim 7
Dependent Claim
95 words
A protective patient drape, comprising; A. a pair of sheets secured together at their peripheries to form a substantially closed chamber; B. said sheets being secured to each other at transversely spaced intervals to divide said chamber into a plurality of longitudinally extending compartments; and C. a quantity of lightweight foam material being received in and substantially filling said compartments; D. said sheets each having a pair of opposed foam-filled neck-engaging members having an arcuate planar and cross-sectional configuration and substantially encircling the neck of the patient and projecting from one end of said drape

Claim 11
Dependent Claim
34 words
A protective patient drape comprising; A. an elongate body of light-weight foam material adapted to cover at least the upper portion of the body of said patient; B. said body being arcuate in cross-section
Claim 12
Dependent Claim
22 words
The drape of claim 8 further characterized by the presence of means for securing said drape to the body of the patient.
Claim 13
Dependent Claim
