Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to an integrated connection device for oropharyngeal tube and endotracheal tube. Background Technology

[0002] For patients using both oropharyngeal tubes and endotracheal tubes, there is no dedicated fixing device between the two when securing them. Medical tape is usually used to connect them to the patient's mouth. During the connection process, the oropharyngeal tube and endotracheal tube are prone to misalignment, affecting their use. At the same time, using tape to fix them can easily cause them to separate from the patient's mouth, resulting in the oropharyngeal tube and endotracheal tube becoming loose.

[0003] Utility model patent CN203107921 U discloses an oropharyngeal airway with a groove, including a main tube and a flange at the top of the main tube. The outer wall of the main tube has an open groove along the axis of the main tube. This oropharyngeal airway is inserted into the pharynx through the mouth using a blind insertion method, and is fixed by the flange, thereby establishing a smooth airway by the main tube pressing against the base of the tongue. This oropharyngeal airway also has an open groove. When endotracheal intubation is required, the endotracheal tube is inserted into the open groove and guided into the trachea, thus providing convenience in places where intubation equipment is lacking. Because the intubation process is performed outside the main tube, the operation of the cannula is avoided, thus ensuring that the intubation can be completed smoothly, quickly and safely. In this patent, by setting an open groove on the oropharyngeal tube as a guide and fixation channel for the placement of the endotracheal tube, when the oropharyngeal tube is inserted into the patient's mouth, the open groove occupies a large space and the edges on both sides of the open groove are thin. During the placement of the oropharyngeal tube, it is very easy to cause damage to the patient's pharynx. Furthermore, after the oropharyngeal tube is connected to the endotracheal tube, there is no connection and fixation between the two and the patient, which makes it easy for displacement and loosening to occur.
