Description

Appurtenance when for pharyngoscope trachea cannula

Technical field

It is especially a kind of for improving expiratory dyspnea patient through orotracheal tube the utility model relates to the field of medical instrument technology The success rate of intubation avoids when pharyngoscope trachea cannula injury of teeth or falls off to slide into air flue, causes asphyxia and threat to life Pharyngoscope auxiliary device.

Background technique

Endotracheal intubation refers to the technology by a special endotracheal tube through glottis merging tracheae, it has also become CPR And with the important measures during the Severe acute disease patient rescue of respiratory dysfunction.And during being placed in tracheae, gas Cannula must could be implemented under direct-view after exposure glottis, conduit direct oral cavity to be inserted into intratracheally, is tracheae by pharyngoscope It is intubated indispensable emergency equipment.Therefore the function and whether being easy to use of pharyngoscope plays in terms of trachea cannula success rate Vital effect.Clinically use traditional pharyngoscope at present, as shown in Figure 1, pharyngoscope include 1 mirror handle and with The matched eyeglass of mirror handle activity, matched eyeglass generally have 3-4 different models according to the case where patient oral cavity.In needs pair When patient carries out oral trachea cannula, the strength that operator needs left hand to hold pharyngoscope handle wrist is put pharyngoscope lens by bicker Entrance cavity is slowly advanced, it is seen that uvula after pushing tongue body to side.Eyeglass is vertically lifted to advance, until epiglottis appears, then Epiglottis is provoked to appear glottis, so that tracheal catheter insertion tracheae is subjected to conduit Carbamide Peroxide or connects assisted mechanical ventilator, This operating process needs operator to have the operation skill ability of very strong wrist power and consummation due to not preferable supporting point It completes, but often occurs causing trachea cannula unsuccessful since wrist power is insufficient or operation is incorrect in actual operation, even It could complete to operate because there was only dependent patient lower teeth as supporting point in operating process, easily patient teeth be caused to fall off in this way Slide into air flue, cause asphyxia and the case where threat to life.Therefore clinically there is following lack in this application method of pharyngoscope at present Point: first is that needing operator that could open air flue with the strength of great strength especially wrist, glottis is sufficiently exposed by tracheae Conduit is placed in air flue, and strength is smaller or undue force cannot sufficiently open air flue exposure glottis；Second is that airway open is not filled Point, gas port cannot be exposed, conduit is easily mistakenly inserted esophagus, and successful intubation is low, delays rescue time, directly affects critical patient Salvage success rate；Third is that Medical Staff intubation gimmick is incorrect, wrist strength is inadequate, the tooth that have to be relied on patient of having no alternative Tooth is that supporting point opens air flue, but easily causes patient teeth to damage or fall off and slide into air flue, causes to suffocate and threat to life.

Utility model content

The technical problem to be solved by the utility model is to provide auxiliary device when a kind of trachea cannula for pharyngoscope, When it can solve pharyngoscope trachea cannula medical worker because wrist strength it is inadequate, caused by airway open is insufficient intubation at Power is low, and relying on tooth is supporting point so as to cause patient teeth's damage or the problem of the sliding into air flue that fall off.

To solve the above-mentioned problems, the technical solution of the utility model is: it is this be used for pharyngoscope trachea cannula when it is auxiliary Helping device includes elastic pad, and the grooving for packing into pharyngoscope lens is provided in the middle part of the elastic pad；The elastic cushion Two middle side parts are provided with groove to body up and down.

In above-mentioned technical proposal, more specifically scheme may is that the cross-sectional shape and the pharyngoscope of the grooving The cross-sectional shape at the covered place of piece is identical.

Another specific scheme may also is that the elastic pad is made of upper cushion cover and lower cushion cover；The upper cushion cover and Lower cushion cover is provided with card slot corresponding with the pharyngoscope lens shape with the contact surface of the pharyngoscope lens.

Another specific scheme may also is that the elastic pad is an air bag body, offers and fills on the air bag body Air valve.

Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:

1, the utility model is independently of the auxiliary device of pharyngoscope setting, is made using soft flexible material, When needing by it on pharyngoscope lens, when pharyngoscope lens enter oral cavity, auxiliary device is just placed between lower teeth, is kept away Injury of teeth or loss of tooth slide into air flue caused by having exempted from because of misoperation, cause to suffocate and threat to life.

2, the utility model structure is simple, and design is rationally, easy to use, when pharyngoscope enters oral cavity, due to device sheet Body can be so that pharyngoscope lens front end be raised, and operator's openable air flue as long as exerting oneself slightly sufficiently exposes glottis, easily It is placed in tracheal catheter, trachea cannula success rate is greatly improved, patient vitals strive for valuable time for rescue.

3, the utility model safety and sanitation, it is cheap, it is applicable to the pharyngoscope of various models, is had a wide range of application.
