AI Technical Summary
Existing tracheostomy tube sealing devices suffer from problems such as misfitting with the inner tube, easy dislodgement of the sealing plug, and frequent replacement during use, leading to operational inconvenience. Current technology struggles to address the issue of misfitting with the inner tube.
A sealing device for tracheostomy tubes was designed. It consists of an insertion bag, a baffle, a distal airbag, and a pressurized airbag. Air is injected through an inflation tube connected to a syringe to inflate the distal airbag and make it fit the inner tube. The baffle prevents the tube from falling out.
It achieves a tight fit with the inner tube body, preventing the sealing plug from falling off, reducing the frequency of replacement, and improving the convenience and safety of use.

[0002] A tracheal cannula, also known as a tracheal tube, is a surgical instrument for treating respiratory diseases, which mainly consists of a cannula and a catheter, and is shaped like a long and thin tube, which can be inserted into the trachea of a patient to help dilate the airway, keep the airway unobstructed, and prevent secretions from blocking, thereby ensuring normal breathing of the patient.
[0003] For patients with a tracheal cannula inserted by tracheotomy, a tube plugging test needs to be performed in the later stage to assess whether the patient has the condition to remove the tracheal cannula and to promote the patient to recover to a normal airway ventilation mode. The existing tube plugging method usually uses a sealing plug to plug the tracheal cannula opening to prevent air leakage. Although the sealing plug can play a plugging role, in actual use, since the sealing plug is buckled on the inner tube opening, and most sealing plugs are sealing plugs of blood collection tubes used in clinical practice, there is often a phenomenon that the sealing plug does not match the inner tube, and the sealing plug is easy to fall off after plugging, so it needs to be frequently replaced, which is very troublesome, and thus needs to be improved.
