ABSTRACT:
A tracheostomy tube assembly has a semi-flexible tube that is coupled at its machine end with an adaptor. The tube is inserted into the patient's trachea through an incision while the adapter is located externally of trachea. The tube has a bore through it that opens into the trachea at its patient end and into the main bore of the adaptor at its machine end. The main bore opens to atmosphere via an aperture in the side of the adaptor. A jet tube is coupled to the adaptor via a narrow bore that is aligned with the main bore. When the jet tube is connected to a high-frequency ventilation source, air is entrained in the adaptor that is directed towards the patient end of the assembly.
