Description

Technical Field

[0001] The invention relates to the technical field of tracheotomy tubes, in particular to a universal tracheotomy tube. Background Art

[0002] Tracheotomy tubes are used in patients with tracheotomy and are divided into metal tubes and cuffed plastic tubes. The current clinical surgical procedure for laryngeal cancer patients is: tracheotomy under local anesthesia, and placement of a cuffed conventional reinforced tube through the tracheostomy. The tube is replaced after surgery according to the surgical situation: a cuffed plastic tube or an uncuffed metal tube.

[0003] Traditional tracheostomy tubes are all round tubes with the same diameter. When used, the patient's wound surface is large and requires professional medical staff in this field to operate. The overall intubation process is cumbersome, resulting in a long overall intubation operation time, and it is impossible to achieve rapid oxygen delivery to the patient. In addition, the current tracheostomy tubes cannot adjust the angle of the tracheostomy tubes when in use, which is not convenient for fixation and connection of the tracheostomy tubes to the ventilator. In addition, the current tracheostomy tubes are not provided with an insertion limit structure, and the insertion depth of the tracheostomy tubes cannot be effectively fixed, which can easily lead to excessive insertion or accidental movement of the intubation tube, which can easily cause secondary damage to the patient's trachea. Therefore, the current tracheostomy tubes have certain disadvantages when in use;

The second airbag 14 is installed at the lower end of the mounting ring 9 and movably sleeved on the upper end of the horn tube 1, one end of the second inflation tube 15 is connected to the second airbag 14, and the second air intake valve 16 is installed at one end of the second inflation tube 15;

[0030] When performing the intubation operation, the staff first inserts the horn tube 1 into the patient's trachea through the guide wire, and pulls out the guide wire, then fixes the threaded tube 12 to the upper end of the horn tube 1 through the internal thread 2, and connects the horn tube 1 to the ventilator through the set trachea joint 13, so that oxygen can be delivered to ensure the patient's oxygen delivery efficiency. During the insertion process, the threaded hose 6 is wrapped by the set mounting ring 9 to ensure the overall strength of the threaded hose 6 and avoid deformation of the threaded hose 6 during the insertion process. After the insertion is completed, the mounting ring 9 is pulled downward, and the friction ring 10 and the mounting ring 9 are separated from the threaded hose 6 with the cooperation of the slider 8 and the slide groove 7. The horn tube 1 is shaped and the angle is adjusted through the threaded hose 6, and then it is connected to the inflation device through the first air inlet valve 5 and the second air inlet valve 16, and the first air bag 3 and the second air bag 14 are inflated through the first inflation tube 4 and the second inflation tube 15. The expansion of the first airbag 3 fixes the horn tube 1, and the expansion of the second airbag 14 limits the overall insertion depth of the horn tube 1 to prevent the horn tube 1 from being inserted too deeply and causing secondary injury to the patient. The device can be fixed to the patient's neck through a fixing rope through the set fixing plate 11 and the mounting hole 17. The set rubber friction ring 10 can fit with the outer wall of the threaded hose 6, and the position of the mounting ring 9 is fixed through the friction between them.

The external thread 18 matches the internal thread 2. The first air inlet valve 5 is a one-way valve, and the second air inlet valve 16 is a one-way valve. The present scheme can be applied to intubation operations of adults and children. Through the set first airbag 3, whether the first airbag 3 is inflated can be controlled according to specific usage conditions. For example, when intubating an adult, the first airbag 3 is inflated and fixed, and when intubating a child, the first airbag 3 may not be inflated.
