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.
