First Claim
1. An inflatable trouser for medical use, comprising a panel of flexible material having an abdominal section and a pair of leg sections, each of said sections having double walls defining a pocket therein, and an inflatable bladder disposed in each of said pockets, wherein the improvement comprises said pockets of said leg sections and the pocket of said abdominal section being disposed in limited overlapping relation with portions of said walls separating the interior of the pocket of said abdominal section from the interiors of the pockets of said leg sections, and said bladders within said pockets of said leg sections being disposed in limited overlapping relation with respect to the bladder in the pocket of said abdominal section.

Abstract
An improved medical anti-shock trouser is disclosed which has replaceable pneumatic bladders so arranged and constructed to allow inflation in use without objectionable perimetric retraction and separation between adjacent bladders. The trouser takes the form of a panel of flexible porous fabric having an abdominal section and a pair of leg sections, each of the sections having a double-walled portion defining a pocket therein. An inflatable bladder is disposed in each of the pockets and, in the disclosed embodiment, the bladders of the leg sections are disposed in limited overlapping relation with respect to the bladder of the abdominal section. Each bladder has a flexible perimetric side wall as well as flexible top and bottom walls. The generally rectangular outline of the abdominal bladder may be interrupted by a longitudinal slit positioned to extend centrally along the lower back of a patient, and/or by a transverse or circumferential slit positioned to extend over the patient'"'"'s abdomen when the trouser is worn. Such slits provide access for trocar or needle insertion into selected sites along the patient'"'"'s abdomen or back without requiring even partial deflation or removal of the trouser and without danger of puncturing the inflated bladder.
