The automatic control-type, portable intravenous infusion apparatus includes an infusion liquid container to which an infusion liquid tube is connected, pressurize it, the infusion liquid tube being provided with a drip-monitoring tube, a connector and an infusion needle with a pressurizing bag for holding the infusion liquid container. The infusion liquid container includes an inflatable pressurizing bag and a sheet member having side ends each fixed to the side ends of the pressurizing bag. Connected to the pressurizing bag are an air tube provided with a mechanical safety valve, a selector valve and an air pump. By introducing air into the infusion liquid container, the pressurizing bag is inflated to apply substantially a constant pressure to the infusion liquid container, thereby flowing the infusion liquid from the container and keeping the dropping speed there substantially constant.
