The present invention provides a feeding and drainage device comprising: a cover body, a connector and a drainage tube. The cover body has a cover plate and a side wall, the cover plate has a coupling hole, and the inner edge of the side wall has a joint portion； the connector has a plug portion that abuts the joint hole, the plug portion has a passage therein, and one end of the plug portion has a through hole for the communication passage. The other end of the plug portion has a combination portion of the communication passages, and a gas permeable portion having a communication passage on one side of the joint head； one end of the draft tube is connected to the combination portion. Thereby, the cover body can be locked to the opening of the bottle body of the liquid nutrient, and the other end of the drainage tube is connected to the nasogastric tube, and the liquid nutrient is introduced into the nasogastric tube by the cooperation of the connection head and the drainage tube for irrigation. Eat, to prevent the pollution of liquid nutrients and the need for human feeding.本創作係提供一種灌食引流裝置，其包含：蓋體、連接頭及引流管。蓋體具有蓋板與側壁，蓋板具有結合孔，側壁內緣具有組接部；連接頭具有與結合孔對接之插接部，插接部內具有通道，插接部一端具有連通通道之穿孔，插接部另一端具有連通通道之組合部，並連接頭一側具有連通通道之透氣部；引流管一端連接組合部。藉此，可將蓋體鎖接於流質營養品之瓶體開口處，並將引流管另一端連接至鼻胃管，而利用連接頭與引流管之配合將流質營養品導入鼻胃管進行灌食，而達到防止流質營養品遭受污染以及不需人力灌食之功效。
