Abstract
The invention presents a compressive hemostatic belt which is easy to handle and is disposable. A balloon 5 inflatable by filling with fluid is mounted on a specific position of a strip 1 made of non-elastic or low-elastic fiber cloth or the like through mounting means, and a pump 8 and a pressure gauge 9 are connected to the balloon 5 through a check valve 6. The balloon 5 is filled with a fluid by manipulating the pump 8 while observing the pressure gauge 9 to inflate the balloon 5, so that only the area where bleeding is to be stopped is put under pressure. Since the balloon 5 is inflated only on the specified area, a piece of hard material 4 may be placed between the balloon 5 and the strip 1. A non-elastic reinforcing member 11 inserted on the opposite side of the balloon 5 can be varied, or the confronting portion of the strip 1 against the balloon 5 can be formed of a non-elastic reinforcing member stronger than the materials of other portions of the strip.
