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.

The utility model relates to a tracheal catheter capable of monitoring air bag pressure, which comprises an air guide tube, an air bag sleeved outside the air guide tube, an inflation tube used for inflating and deflating the air bag and a pressure measuring device capable of monitoring the air bag pressure, and the pressure measuring device comprises a pressure indicating bag arranged outside the air bag and a liquid storage bag sleeved outside the pressure indicating bag. The pressure indication bag is communicated with the air bag through an inflation tube, and indication liquid used for displaying expansion and contraction changes of the pressure indication bag is arranged in the liquid storage bag. After the technical scheme is adopted, the liquid storage bag is arranged outside the air bag, the liquid storage bag is located outside the human body during use, safety is higher, risks caused by accidental leakage are avoided, the pressure indicating bag and the liquid storage bag are used for monitoring the pressure change of the air bag, simplicity and intuition are achieved, and even if the pressure change is small, the liquid storage bag can not be used. The liquid level sensor has the advantage of being convenient to monitor.

This utility model belongs to the field of medical device technology and provides a disposable urinary catheter drainage device, including a urinary catheter, a sealing connector, and a reservoir bag connected in sequence. The reservoir bag is a folded reservoir bag with at least one pre-compression fold line. The reservoir bag is provided with a drainage tube communicating with an internal reservoir cavity. The sealing connector includes an insert at the end of the urinary catheter and a sleeve at the end of the drainage tube. The insert is detachably inserted into the sleeve. The disposable urinary catheter drainage device provided by this utility model improves portability and reduces the impact on patient activity by using a folded reservoir bag, increases urine storage capacity, and allows for detachable connection between the reservoir bag and the urinary catheter through the sealing connector, facilitating the replacement of the reservoir bag and avoiding urethral mucosal infection damage caused by repeated insertion and removal of the catheter.
