A system for the air reduction of intussusception in infants and children. The system comprises a main tube terminating of its distal end in an enema tip. The proximal end of the main tube is connected to an in- line filter which stops reflux of aerosol and liquid/solid contaminants therebeyond. The filter is connected to a three-way, lever- actuated stopcock which, in turn, is connected to a hand-operated insufflator bulb. The air reduction system is provided with an aneroid gauge. The guage and bulb may constitute a reusable, integral assembly, the remainder of the system being disposable. The entire system may be disposable with a disposable gauge connected ahead of the in-line filter. A reusable gauge may be remotely located and connected to the air reduction system via a branch tube and a T-fitting located between the filter and the three-way valve, all of the system save the remote gauge being disposable. All of the embodiments may be provided with a pop-off valve and adapter located between the filter and the stopcock. All of the embodiments are held and actuated by one hand of the operator, the lever of the stopcock being operated in fingertip, trigger-like fashion.
