Above-mentioned foot-operated auxiliary device that injects for defecation radiography, inject drum tail side one side and seted up the pneumatic tube, pneumatic tube head end and inject the drum intercommunication, the tail end is sealed by the rubber buffer.

Above-mentioned foot-operated auxiliary device that injects for defecation radiography, inject the drum and embed and have short columniform pneumatic piston, between pneumatic piston and pneumatic tube opening, be provided with along injecting the restriction boundary ring that the drum inner wall encircles a week uplift.

In the pedal type injection auxiliary device for defecation radiography, in the inflation component, the tail end of the inflation conduit is provided with the metal needle core, the head end of the inflation conduit is connected with the telescopic air bag through the one-way air valve, and the wall of the telescopic air bag is provided with the one-way air inlet.

Above-mentioned defecation radiography is with foot-operated auxiliary device that pushes, aerify the part and be connected with supplementary injection part behind the metal nook closing member puncture rubber buffer through terminal.

The beneficial effects of the utility model are that, this device utilizes foot-operated to inject, does benefit to vacating doctor's both hands operating equipment, and the guarantee pipe does not drop and avoids intestines tube pressure harm, conveniently carries out aseptic technique etc.. The head end of the injection cylinder is provided with an inner sheet and an outer sheet which are symmetrical, a clamping groove is formed between the inner sheet and the outer sheet, the tail end of a 50ml medical injector hollow cylinder can be firmly fixed, and stable injection operation is facilitated. The air entering the air pressure pipe generates larger air pressure to push the pneumatic piston to slide in the injection cylinder, which is beneficial to providing larger thrust to indirectly push the piston handle of the medical injector to generate injection action. The limiting boundary ring can limit the moving range of the pneumatic piston, and is favorable for ensuring that the pneumatic piston is always positioned at the working position of the far end of the opening of the pneumatic tube. The tail end of the inflation conduit is provided with a metal needle core which is beneficial to puncture connection with a rubber plug at the tail end of the pneumatic tube and air injection to generate air pressure. The head end of the inflatable catheter is connected with the telescopic air bag through the one-way air valve, which is beneficial to ensuring that air flows in one direction in the inflatable catheter and is injected into the injection cylinder. The telescopic air bag is provided with the one-way air inlet, which is beneficial to ensuring the one-way inflation function of the telescopic air bag and providing enough push air pressure.
