Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A pressure actuated bandage adapted to be wrapped around a body portion and fluid pressure applied to a dressing to force it into contact with a specific body location, said bandage comprising an elongated flexible support consisting of two layers of flexible material peripherally connected to form a pouch, spring means mounted on the flexible support to resiliently retain said support in a semicircular position, a dressing packet affixed to the concave face of the flexible support, an inflatable bladder positioned in the pouch beneath the dressing packet, an extension band secured to one end of the flexible support, cooperating Velcro-fastening means affixed to the extension band and the convex face of the flexible support whereby the extension band may be secured to the convex face of the flexible support when it is wrapped therearound in applying the bandage to a body portion, and a fluid pressure system connected to the bladder for inflating same and causing a radially inward pressure to be exerted on the dressing packet to cause it to firmly bear upon a specific body portion.
Claim 2
Dependent Claim
179 words
A pressure actuated bandage adapted to be wrapped around a body portion and fluid pressure applied to a dressing to force it into contact with a specific body location, said bandage comprising an elongated flexible support consisting of two layers of flexible material peripherally connected to form a pouch, spring means mounted on the flexible support to resiliently retain said support in a semicircular position, a dressing packet affixed to the concave face of the flexible support, an inflatable bladder positioned in the pouch beneath the dressing packet, an extension band secured to one end of the flexible support, cooperating Velcro-fastening means affixed to the extension band and the convex face of the flexible support whereby the extension band may be secured to the convex face of the flexible support when it is wrapped therearound in applying the bandage to a body portion, and a fluid pressure system connected to the bladder for inflating same and causing a radially inward pressure to be exerted on the dressing packet to cause it to firmly bear upon a specific body portion.
Claim 3
Dependent Claim
25 words
The invention as set forth in claim 1 and wherein the fluid pressure system includes a manually operated pump in the form of a bulb.
Claim 4
Dependent Claim
27 words
The invention as set forth in claim 2 and wherein the fluid pressure system includes a variably adjustable exhaust valve for releasing pressure in the inflated bladder.
Claim 5
Dependent Claim
24 words
The invention as set forth in claim 1 and wherein the fluid pressure system includes a gage port and a pressure gage mounted therein.
Claim 6
Dependent Claim
75 words
The invention as set forth in claim 1 and wherein a retaining bar is secured to the end of the flexible support opposite to that from which the extension band extends, said retaining bar having a slot coextensive with the width of said band whereby in the application of the bandage to a body portion the band will be introduced into the slot with its direction reversed so as to initially tension the flexible support.
Claim 7
Dependent Claim
196 words
A pressure actuated bandage adapted to be wrapped around a body portion and fluid pressure applied to a dressing to force it into contact with a specific body location, said bandage comprising an elongated flexible support consisting of two layers of flexible material peripherally connected to form a pouch, spring means mounted on the flexible support to resiliently retain said support in a semicircular position, a dressing packet affixed to the concave face of the flexible support, an inflatable bladder positioned in the pouch beneath the dressing packet, a retaining bar on one end of the flexible support, said retaining bar having a transverse slot with an opening at one side of the bar so that the other end portion of the flexible support may be slidably inserted into the slot through said opening and its direction reversed so as to initially tension the flexible support in wrapped condition, means for securing the reversed flexible support portion in wrapped condition, and a fluid pressure system connected to the bladder for inflating same and causing a radially inward pressure to be exerted on the dressing packet to cause it to Firmly bear upon a specific body portion.
