Abstract
Abstract The improvement in an airtight bandage which comprises an inflatable bag and is adapted to be wrapped around a limb of a person or animal for damming up the blood therein to permit blood pressure and other measurements to be made, wherein for attaining more accurate measurement the bandage consists of two stripshaped layers of fabric which are coated with an air-impermeable layer at least on the inner sides facing each other which are completely bonded together with the exception of an area where merely the edges of the two layers are bonded together like a frame s6 as to form the inflatable bag.

Claim 1
Independent Claim
164 words
An airtight bandage adapted to be wrapped around a limb of a person or animal for damming up the blood therein so as to permit blood pressure or other measurements to be made, comprising a band consisting of two superimposed layers of a fabric coated at least on the inner sides facing each other with an airimpermeable coating, said band having a shorter part adjacent to one end and a longer part continuous with said shorter part and extending to the other end, said coated layers of said longer part being completely bonded together along their entire inner surfaces, and said coated layers of said shorter part being bonded together only along their edges so that the central area forms an inflatable bag between said layers adapted to be applied at least partly around said limb, while said longer part is adapted to be wrapped around said limb, said bag having at least one small opening adapted to be connected to an air pump.
