INTRAVENOUS INFUSION APPARATUS

摘要

An intravenous infusion apparatus is provided to prevent the risk of backflow of blood regardless of the positions of the intravenous infusion bag and the patient's heart and to inject the intravenous infusion stably. The intravenous infusion apparatus has an intravenous infusion bag container(10) which pressurizes an intravenous infusion bag(20) with its own internal pressure. The intravenous infusion container(10) is connected to an air pump(50). An air pressure sensor(48) and a solenoid valve(43) are installed on an air supply conduit(90) between the intravenous infusion bag container(10) and the air pump(50). A control portion is provided to control the valve(43) and the air pump(50) according to the internal pressure of the intravenous infusion bag container(10) detected by the air pressure detection sensor(48) to make the internal pressure of the intravenous infusion bag container(10) maintained to be a reference pressure.
