Abstract

The invention discloses a drainage nursing device special for hepatobiliary surgery. The drainage nursing device comprises a liquid suction head, a drainage tube and a box, a liquid collection chamberis arranged inside the box, one ends, away from the box, of a diversion tube and a guide tube are connected with the drainage tube, an adjusting seat is fixed at one end of the drainage tube, one end, away from the diversion tube and the guide tube, of the drainage tube is connected with the liquid suction head, first liquid suction ports are uniformly arranged on the side face of the liquid suction head, an inner sleeve head is arranged inside the liquid suction head, and a wavy liquid suction head wraps the outer side of a crossed limiting plate. By the drainage nursing device, convenienceis brought to adjusting caliber in the process of negative pressure reduction, hepatobiliary inside pressure is maintained stable, secondary damage caused to liver and gall is prevented; convenience is brought to increasing pressure when cleaning liquid enters the inside of a connection passage, impact force of the cleaning liquid is improved, and convenience is brought to automatically generatingnegative pressure according to blockage conditions to adjust distance between a second limiting block and a second piston so as to adjust size of an opening of a flushing passage.
