The improvement oropharyngeal airway
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of oropharyngeal airway of assisted ventilation when rescuing life, this apparatus can prevent that breather from deviating from the oral cavity, and can assist and inhale expectorant.
Background technology
At present, the oropharyngeal airway that various big hospital generally uses is mainly used in the tongue suffix and causes dyspneic patient, because these patients obnubilation often, perhaps spirit is irritated, cause oropharyngeal airway to deviate from the oral cavity easily, re-initiation respiratory tract obstruction and threat to life; Some patient is more because of oropharynx or respiratory secretions, if untimely absorption can cause respiratory tract obstruction and death by suffocation.Tradition oropharyngeal airway insertion depth is difficult for holding, and every patient's oropharynx length differs, and inserts dark or crosses the shallow best oropharynx ventilatory effect that all is difficult to reach, and just need change suitable oropharyngeal airway repeatedly at this moment, and deviate from the oral cavity easily after the insertion.Traditional in addition oropharyngeal airway is inhaled expectorant because of the tongue body obesity easily hinders the medical worker after inserting oropharynx, causes many difficulties to clinical rescue.
Summary of the invention
Shortcomings such as deviating from the oral cavity easily in order to overcome traditional oropharyngeal airway, be difficult for to inhale expectorant, insertion depth can not be adjusted, this utility model provides a kind of oropharyngeal airway of improvement, this breather provides the double fixed system, not only fixation behind the insertion pars oralis pharyngis, and help the medical worker and inhale expectorant, the incidence rate of significantly reduced aspiration pneumonitis, suffocating, and insertion depth can arbitrarily be adjusted, improve critical patient's salvage success rate greatly, and saved cost.
The technical scheme that its technical problem that solves this utility model adopts is: at traditional oropharyngeal airway mouth end a slidably snap close (as shown in Figure 1 and Figure 2) is installed, this snap close can slide up and down adjusts the degree of depth that oropharyngeal airway enters the oral cavity, the oropharyngeal airway body wall is marked with graduation mark and can be used as degree of depth reference, fastening snap close after the good proper depth to be adjusted, this snap close just can not slide.There are two baffle plates at these snap close two ends, and outer baffle is placed on outside the lip, and Internal baffle is placed on the tooth medial surface, and the centre just in time is stuck between the lower teeth, make mouth be difficult for deviating from because of breather, and this is the first heavy fixed system.The outer baffle two ends of snap close are provided with two subsidiary (as shown in Figure 3, Figure 4), can tie up admittedly around patient's neck occipitalia, have more strengthened the fixing of oropharyngeal airway, make it be difficult to slippage, and this is the second heavy fixed system.The oropharyngeal airway veutro is provided with the wing spatula of crawling, and plate is provided with glossal canal and aperture, is beneficial to press tongue ventilation behind the tongue.1cm labelling graduation mark in the every interval of oropharyngeal airway body wall is convenient to point out insertion depth.After the improvement oropharyngeal airway inserted oropharynx, the wing of crawling spatula can be pushed down tongue body, and vacating space is convenient to the medical worker and is inhaled expectorant.Improvement oropharyngeal airway pharynx end is designed to the inclined-plane, has not only increased breathing area than facing directly, and has been more conducive to inhale expectorant.
The beneficial effects of the utility model are that the improvement oropharyngeal airway inserts pars oralis pharyngis after the double fixed system fixedly is difficult for the slippage outlet plenum; Insertion depth can arbitrarily be adjusted, and is applicable to the crowd of the different oropharynx degree of depth; Improvement oropharyngeal airway veutro is provided with the wing spatula of crawling, and can sharply inhale expectorant after pushing down tongue.This instrumentation is simple, and is easy to use, and high value for clinical application and economic results in society are arranged.

The specific embodiment
In Fig. 1, Fig. 2, snap close (12) is enclosed within on the improvement oropharyngeal airway, and because of the protection of a mouthful end-stopping plate (5) is arranged, snap close can not skid off breather.The snap close that slides according to the adjustment of patient's oropharynx degree of depth behind the oropharyngeal airway insertion pars oralis pharyngis, make the Internal baffle (11) of snap close prop up the tooth inboard, outer baffle (8) just in time props up the lip outside, push outer baffle with strength, because the snap close side is that wedge shape is damaged, outer baffle is made up of two dentation interfaces (9) up and down, pushes latter two interface fastening, internal ring is close to the oropharyngeal airway wall, and snap close just can not move.Subsidiary (10) of outer baffle both sides but colligation fixing port Pharynx trachea after twining the neck occipitalia.The wing of crawling spatula is pushed down tongue body, and the glossal canal on the spatula can prevent that tongue from moving, and can be beneficial to suction expectorant by the space above the spatula.Improvement oropharyngeal airway mouth end can connect respirator or simple and easy inflating balloon interface assisted ventilation.The material of improvement oropharyngeal airway is selected rigid plastics for use, and certain plasticity is arranged.
