Abstract

This utility model discloses a postoperative nasal drainage device, comprising: a distribution valve, drainage tubes, and a reservoir bag. The distribution valve has two inlet holes and one outlet hole. A partition plate is fitted into the distribution valve, separating the two inlet holes. A rotating shaft is rotatably mounted within the partition plate, and first, second, and third baffles are mounted on the shaft. The first baffle cooperates with one inlet hole, and the second and third baffles cooperate with the other inlet hole. A reservoir bag is fitted into the outlet hole, and a partition plate is installed within the reservoir bag. The partition plate and the partition plate are interlocked. A first hydrophobic membrane is installed within the partition plate. A negative pressure hole is provided on the reservoir bag, and a second hydrophobic membrane and a one-way valve are installed within the negative pressure hole. A drainage tube is connected to each of the two inlet holes, and the drainage tube is equipped with a one-way Luer connector and a detachable drainage end. The distribution valve allows adjustment between single-inlet and dual-inlet modes depending on whether the surgery is performed in a single or double nasal cavity.
