A coupling for connecting an air supply to a respiratory support device has a latching mechanism which prevents the coupling from inadvertently axially displacing from the respiratory support device after they have been mated in a pneumatically discrete path. Non-axial forces are used to disengage the coupling from the respiratory support device. The coupling may include a trailing end adapter which permits rotation of the coupling relative to the air supply rather than to the respiratory support device.

A coupling for connecting a ventilator tube to a tracheotomy tube has a latching mechanism which prevents the coupling from axially displacing a tapered tubular extension of the tracheotomy tube after they have been mated in a pneumatically discrete path. For use with known adult tracheotomy tubes which have inner and outer cannulas, the latching mechanism engages the coupling with the leading end of the outer cannula collar with the inner cannula collar sandwiched therebetween. For use with known one piece children's tracheotomy tubes, the latching mechanism is a clamshell contoured to concentrically grip the tapered tubular extension of the tracheotomy tube. Interlocking the coupling and the tracheotomy tube prevents them from inadvertently axially displacing from each other. Non-axial force disengages the coupling from the tracheotomy tube so that the coupling can be axially displaced without exertion of excessive axial force on the system and the patient.

Tracheostomy apparatus includes a needle with a doppler ultrasound transducer mounted within it close to its patient end and connected to a monitor. Two electrodes are insulated from one another on the external surface of the needle close to its patient end. The electrodes are also connected to the monitor. The needle supports a catheter on its outer surface. As the needle is inserted through tissue overlying the trachea, the ultrasound transducer detects the presence of any nearby blood vessels and gives an audible indication on the monitor. The monitor also responds to a rise in impedance between the electrodes indicative of entry of the end of the needle into the trachea so that the needle can be removed to leave the catheter in place. A guide is then inserted through the catheter and the path into the trachea is enlarged with a dilator sufficiently to receive a tracheostomy tube.

BACKGROUND: Tracheotomy is used to assist patients who require mechanical ventilation. Tracheostomy is a common surgical procedure for intensive care patients. The goals of tracheotomy are to bypass the upper airway, facilitate removal of tracheobronchial secretions, prevent aspiration of gastric contents, and to control the airway for prolonged mechanical ventilation. METHOD: The hypothesis to improve the design of the tracheostomy tube, making it easier to use and eliminating most of the disadvantages found in prior tracheostomy tubes. RESULTS: This device is an improved tracheostomy tube designed with the balloon cuff (18), guide balloon (26), balloon connector (32) and guide balloon valve (24) located on the inner cannula (12). The major improvement in this tracheostomy tube is that the removal of the outer cannula will not be necessary when the balloon cuff is damaged, since replacing the inner cuffed cannula corrects the problem.
