Oropharyngeal Airway Disposable Medical Oropharyngeal Guedel Airway for Single Use with All Sizes

Product use:

1. Maintain the patency of the upper respiratory tract: for anesthesia patients or comatose patients, the tongue and epigrettitis may fall backward into the posterior pharyngeal wall, resulting in upper respiratory tract obstruction, due to the relaxation of the oral floor and pharynx muscles that support the tongue to maintain the patency of the upper respiratory tract. When correctly inserted into the oropharyngeal airway, its front end can lift the tongue and epiglotis from the posterior pharyngeal wall, thus achieving the purpose of preventing or treating upper respiratory tract obstruction. Compared with other methods of maintaining upper airway patency, such as chin lift, mandibular support, and tracheal intubation, insertion of the oropharyngeal airway did not affect the stability of the patient's cervical spine.
2.  Good for sputum aspiration: patients with false bulbar paralysis, dysphagia, weak cough, patients with long-term bed rest combined with lung infection without intubation and tracheotomy, repeated stimulation of nasal sputum aspiration is easy to damage nasal mucosa, patients with oral sputum aspiration are easy to bite the sputum aspiration tube, conflict and do not cooperate, sputum aspiration after placement of oropharyngeal airway operation method is simple. As long as the depth of insertion through the mouth is about 5~6cm deeper than that through the nasal cavity, the effect of stimulating cough response is stronger, so it is easy to cough phlegm deep in the airway to the upper respiratory tract and conducive to suction.
3. Used as a dental pad: In addition to maintaining airway patency, the oropharyngeal airway can also be used as a dental pad to prevent patients from biting the endotracheal catheter inserted in the mouth. In epileptic seizures, the oropharyngeal airway can not only maintain the patient's airway, but also prevent it from biting the tongue.
4. Other uses: assisting in oropharyngeal attraction; In some patients with mask ventilation, the use of oropharyngeal ventilation is helpful to achieve mask sealing, such as patients without dental disease; Assist in the insertion of oropharynx and gastric tubes. 

How to use:

1. To have a satisfactory depth of anesthesia, in order to inhibit throat reflex. Pharyngeal spray or local anesthetic can be applied.
2. Choose a suitable oropharyngeal airway whose length (outside the mouth) is approximately equivalent to the length from the incisor to the mandibular Angle.
3. Open the patient's mouth, place the tongue retractor at the base of the tongue, and lift the tongue upward to leave the posterior pharyngeal wall.
4. Put the oropharyngeal airway into the mouth with the incisor protruding 1~2cm from its end. At this time, the oropharyngeal airway is about to reach the posterior wall of the oropharynx. If the tip of the vent just reaches the base of the tongue and the flange is already in the teeth, it indicates that the vent is too small.
5. Hold the lower jaw with both hands so that the tongue is away from the back wall of the pharynx, and then push the airway down at least 2cm with the thumb so that the curvature of the airway pharynx is behind the base of the tongue.
6. Relax the mandibular condyle and return it to the temporal condyle joint.
7. Examine the mouth to prevent tongue or lip clips from getting between the teeth and the vent.
