Abstract
Abstract An inflatable cuff for deriving blood pressure data by uniform vessel occlusion in all shape limbs to provide accurate compression comprising an inflatable bag and a pad positioned lengthwise in the cuff and in an overlying relationship within the cuff, the pad being smaller than the bag in its width dimension and distally positioned on the cuff and connected so as to anchor the cuff to the subject''s extremity and generate a substantially uniform pressure compression pattern along the extremity length under the cuff.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
An inflatable medical cuff adapted to encircle and constrict an extremity of a subject for deriving blood pressure data including: an inflatable bag means; a pad means, said cuff including means for restraining said bag and said pad means in said cuff; said inflatable bag means and pad means positioned lengthwise along said cuff in an overlying relationship within the cuff, said pad means being smaller than the bag means in its transverse dimension perpendicular to the lengthwise direction; said pad means having a longitudinal centerline which is transversely offset relative to a longitudinal centerline of the bag means enabling said pad menas to be distally positioned transversely on the cuff.
Claim 2
Dependent Claim
111 words
