This utility model discloses an integrated multifunctional
intubation device with flushing, drainage, and
drug administration functions. The device includes an
intubation tube, a three-way
drug administration flushing and drainage device, a connecting tube, and an anti-
backflow negative pressure drainage ball. The inner surface of the
intubation tube has supporting teeth to prevent compression closure. One end is a connecting section, and the working section's
tail end is fish-mouth shaped with staggered flushing holes on its
smooth surface. The outer circumference of the intubation tube has an "I"-shaped fixing ring. The three-way valve is connected to the anti-
backflow negative pressure drainage ball through the connecting tube, allowing liquid in the intubation tube to flow into the drainage ball, preventing
backflow and allowing liquid to flow out through the drain hole. The connections between the connecting tube, the intubation tube, and the three-way valve are all threaded and tightened. This device integrates multiple functions, has a reasonable structural design, and can effectively realize flushing, drainage, and
drug administration operations, while also preventing blockage of the intubation tube due to compression and dislodgement due to external force.
