Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a tracheal intubation light stick with an oxygen supply pipeline. Background Art

[0002] The endotracheal light wand is a medical device used to assist in endotracheal intubation and is widely used in emergency, anesthesia, and intensive care settings where an artificial airway is required. Intubation is a crucial technique for inserting a tube into the trachea to ensure the patient receives adequate oxygen or mechanical ventilation. It can be life-saving, especially in emergency situations such as airway obstruction or respiratory failure. However, due to the patient's anatomy, insufficient lighting, or a limited field of view, the endotracheal intubation process can sometimes be difficult. In particular, intubation failure can lead to serious consequences if the intubation angle is inappropriate or the airway structure is unclear.

[0003] To improve the success rate of intubation, endotracheal intubation light wands have emerged. Made of flexible material, these light wands can bend and adjust to the patient's laryngeal and airway anatomy. A light-emitting head at one end shines light through the skin or airway lining, helping doctors accurately determine the position of the trachea and effectively guide the intubation route. The light wand's illumination is particularly important in low-light conditions and when the airway anatomy is unclear, significantly improving visibility and reducing the difficulty of the procedure.

[0004] The endotracheal light wand is not only suitable for routine endotracheal intubation, but is also extremely useful for patients with difficult intubation, such as those with complex medical conditions such as cervical spine injuries, airway stenosis, and obesity. This tool helps reduce the risk of intubation failure, shorten intubation time, and lower the incidence of patient complications.

[0005] Endotracheal intubation light sticks are generally available in two types: disposable and reusable. The former reduces the risk of cross-infection, while the latter offers greater economic advantages. Their ease of use has made them popular in clinical practice, becoming a crucial aid for medical personnel in airway management, effectively improving the safety and success rate of endotracheal intubation.

[0006] The existing endotracheal intubation light stick structure is not convenient enough when connecting the oxygen tube, and the operation is complicated and difficult to operate. Therefore, there is an urgent need for an endotracheal intubation light stick with oxygen delivery function that can simplify the operation and improve safety. Utility Model Content

[0007] In response to the deficiencies of the existing technology, the utility model provides a tracheal intubation light stick with an oxygen supply pipeline.

An oxygen input interface 5 is provided on the side wall of the first base 3, and a connecting key 19 is provided at the connection between the first base 3 and the second base 4.

[0035] The connector 6 includes an outer shell, a compression sleeve 13 and an inner pressure ring 8. The compression sleeve 13 is arranged inside the outer shell.

[0037] A first external thread structure 16 is provided on the outer side of the first end of the hollow cylindrical structure, and a second internal thread structure matching the first external thread structure 16 is provided on the inner side wall of the fixing cap 2 .
