Description

Technical Field

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

[0002] Tracheostomy tubes are used in patients with tracheostomies and are available in metal tubes and cuffed plastic tubes. The current clinical surgical procedure for laryngeal cancer patients involves tracheotomy under local anesthesia, followed by placement of a conventional cuffed reinforced tube through the tracheostomy. Postoperatively, the tube is replaced based on the surgical situation: either 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 personnel in this field to operate. The overall intubation process is cumbersome, resulting in a long overall intubation operation time and inability to achieve rapid oxygen delivery to the patient. In addition, the current tracheostomy tubes cannot be adjusted at an angle during use, making it inconvenient to fix and connect the tracheostomy tube to the ventilator. In addition, the current tracheostomy tubes are not provided with an insertion limit structure, and the insertion depth of the tracheostomy tube cannot be effectively fixed, which can easily lead to over-deep 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 used;

[0004] And the existing patent discloses CN202120906526.1 combined percutaneous tracheostomy catheter, which relates to the field of medical equipment, including an inner core, a catheter, and an outer shell, the inner core including a first channel, a second channel, and a core head that are interconnected internally; one end of the second channel is connected to the first channel, and the other end of the second channel is connected to the core head; a first protrusion is provided on the second channel; a second protrusion is provided on the catheter; the outer shell includes an upper shell and a lower shell, a third protrusion is provided on the right side of the upper shell, and a groove is provided on the right side of the lower shell for use with the third protrusion; a locking block is provided on the left side of the upper shell, and a locking groove is provided on the left side of the lower shell for use with the locking block; compared with traditional percutaneous dilatation tracheostomy catheters, this device causes less trauma and has advantages similar to the bull horn dilation method; compared with the bull horn dilation catheter, the use of the device can reduce one operation step, shorten the operation time, and improve treatment efficiency; the consumables required for production are reduced, and the cost is reduced, but the following problems still exist;

[0005] The operating method adopted in this patent document cannot adjust the angle of the tracheostomy tube during use, is not convenient for fixing, and is not convenient for connecting the tracheostomy tube to the ventilator. In addition, there is no insertion limit structure, and the insertion depth of the tracheostomy tube cannot be effectively fixed.

[0006] In view of this, we conducted in-depth research on the above issues, which led to the present case. Summary of the Invention

[0014] A mounting hole is provided on the upper end of the fixing piece.

[0015] One end of the threaded pipe is processed with an external thread, and the external thread is movably embedded in the internal thread.

The first airbag 3 is provided to control whether the first airbag 3 is inflated according to the specific usage. For example, when intubating an adult, the first airbag 3 is inflated and fixed, while when intubating a child, the first airbag 3 does not need to be inflated.
