The utility model relates to a pressure maintaining alarm mechanism of an
artery compression bag and the
artery compression bag, and belongs to the technical field of
medical instruments. The pressure maintaining alarm mechanism comprises a
barrel, a
piston, a sliding rod, balancing weights and a connector, the
piston is arranged in the
barrel, the sliding rod is arranged in the center of the end face of the top of the
piston, and the multiple balancing weights are arranged on the sliding rod in a stacked and sleeved mode. The center of the bottom of the cylinder is connected with a connector through a communicating hose. According to the pressure-maintaining alarm mechanism and the
artery pressurizing bag, the pressure in the bag body can be continuously maintained, an alarm can be given out, regular observation and pressure supplement are not needed, and the labor intensity of a plurality of pressurizing bags can be greatly reduced. The pressure in the pressurizing bag can be adjusted, so that the conveying speed can be adjusted according to personal physique, and the pain of a patient during
rapid infusion can be reduced. The infusion amount can be adjusted through the scales, alarm reminding can be conducted after infusion is completed, and the labor intensity is further reduced. The problem that the labor intensity is high due to the fact that an existing pressurizing bag needs to be continuous is solved.
