Provided is an intussusception position-restoration system, comprising an intussusception position-restoration device (100) and a disposable consumable structure (200); the disposable consumable structure (200) has a liquid inlet part (20), a waste liquid discharge part (30), an insertion part (10), and a pressure monitoring connection part (40); the intussusception position-restoration device (100) comprises an automatic liquid feeding apparatus (1) capable of pumping perfusate, a pressure control device (2) which can set the maximum perfusion pressure of the perfusate during the intussusception position restoration and monitor the perfusate pressure in real time, a flow-rate adjusting apparatus (3) used for adjusting the perfusion flow rate of the perfusate, an active pressure relief apparatus (4) which can reduce the pressure of the perfusate, a main control system (8) used for outputting a main control signal, and so on. The intussusception position-restoration system is controlled by means of the linked systems for perfusate speed control, perfusate pressure control, and active pressure relief control, and can improve the convenience and real-time performance of reduction pressure control during an intussusception position-restoration operation, reducing the burden on doctors and improving patient safety. Also disclosed is a corresponding intussusception position-restoration method.La présente invention concerne un système de positionnement-restauration d'invagination, comprenant un dispositif de positionnement-restauration d'invagination (100) et une structure consommable jetable (200) ; la structure consommable jetable (200) ayant une partie orifice d'entrée de liquide (20), une partie d'évacuation de liquide déchet (30), une partie d'insertion (10), et une partie de liaison de suivi de pression (40) ; le dispositif de positionnement-restauration d'invagination (100) comprenant un appareil d'alimentation automatique de liquide (1) susceptible de pomper un per
