Description

Quick-fixing type oropharynx breather pipe

[ field of technology ]

The utility model relates to the technical field of oropharynx ventilation pipes, in particular to the technical field of fast-fixing type oropharynx ventilation pipes.

[ background Art ]

After general anesthesia tube drawing, the consciousness and muscle strength of the patient are not completely recovered, and the tongue body moves backwards under the action of gravity, so that the soft tissues of the pharyngeal cavity are easy to collapse and cling together and block a narrow air outlet channel, and further the problems of acute upper respiratory obstruction, hypoxia, carbon dioxide accumulation and the like are caused. For obese, pediatric, and deeply sedated patients, this complication is more likely to occur. In order to avoid the phenomenon clinically, an oropharynx breather pipe is often adopted to separate the tongue root of the falling back from the posterior wall of the oropharynx and protect the unobstructed respiratory tract.

Referring to fig. 1, a conventional oropharyngeal airway is generally made of elastic rubber or plastic and includes a flange a, a bite block portion b and a pharyngeal flexure portion c. After the successful placement of the tube, the pharyngeal curvature c may extend into the patient's throat with the bite block portion b positioned between the patient's upper and lower teeth and the flange a exposed outside the upper and lower incisors. In the process of dysphoria, undersensing or transition from coma to wakefulness, the patient often spits out the oropharynx breather pipe due to congenital physiological reflex, and then the oropharynx breather pipe is separated or displaced. For this reason, medical tapes are also commonly used clinically to affix the flange a to both sides of the cheek in a crossed fashion. However, the medical adhesive tape is once wetted, the phenomenon of falling off due to the decrease of viscosity occurs, and if the patient is allergic to the medical adhesive tape, allergic dermatitis or crumbling may occur at the sticking position, thereby causing secondary infection, and easily causing additional pain to the patient.

For this reason, some of the practitioners have proposed lip-covered retainers such as the oropharyngeal airway retainers disclosed in the patent publication CN 203154518U. Such a fixator chooses to add a splint to achieve the clamping fixation of the oropharyngeal airway, however, the splint covering the mouth of the patient is prone to cause discomfort because the binding force is directly applied to the lips and cheeks of the patient. In addition, some of the practitioners choose to use adjustable headgear to connect the patient's head to the oropharyngeal airway, such as the oropharyngeal airway retainer disclosed in the patent publication CN 203915707U. However, the wear and size adjustment of the adjustable headgear is cumbersome and does not allow for quick securement of the oropharyngeal airway.
