Summary of the invention
The purpose of this utility model is for overcoming the drawback of above-mentioned existence, designing a kind of at the throat breathing guide catheter that can not have to finish under autonomous respiration or the dark anesthesia trachea, intrabronchial inspection and operation.Realize the purpose of this utility model.The technical scheme of being taked is: improved on the basis of traditional endotracheal tube and trachealgia associating conduit.This throat breathing guide catheter includes ventilation inlet, throat breathing guide catheter esophagus inlet, pharyngolaryngeal cavity airbag aeration mouth, esophageal inflatable balloon mouth, esophageal inflatable balloon pipe, food meatus, pharyngolaryngeal cavity air bag, esophageal balloon, throat breathing guide catheter esophagus opening, pharyngolaryngeal cavity airbag inflation pipe, airway pressure operates pipe and throat is breathed guide catheter trachea opening.It is characterized in that setting up the unidirectional ventilation flap valve of a sealing at the ventilation entrance side of airway pressure operation pipe.The unidirectional ventilation flap valve of said sealing is unidirectional ventilation SANYE flap valve.
This utility model is that conduit is inserted esophagus, and not needing laryngoscope to expose can insert, and studies show that, blind when slotting, the probability that conduit enters esophagus is 83%, and the probability that enters trachea is 17%.The blind hemodynamic acute variation that causes in the time of to avoid provoking epiglottis and expose glottis of inserting.Cooperate necessary maneuver and position, the blind probability that is inserted into esophagus is higher.This utility model is simple to operation, and need not the patient head layback during intubate and peep larynx, the success rate height, and ventilatory effect is satisfied.So be applicable to high larynx, the difficulty in opening mouth patient that cervical vertebra is tetanic or fracture, micromandible or mandibular joint are tetanic and other reason causes especially, also can be used for causing glottis difficult exposure person because of reasons such as maxillar part traumatic hemorrhage or frequent vomitings.Can be used for pre hospital care, cardio-pulmonary resuscitation and disposal of Difficult Fracheal Intubation.Can be used as the effective ways of keeping airway patency and oxygen supply in trachea in emergency circumstances or the cricothyroid laryngotomy.Can A/C behind the bottleneck throat sleeve bag gas-filling in order to avoid deviate from, in patient's safety, convenient in transit.Its hollow tubing conductor can be drawn aqueous gastric content, and esophageal balloon plays the effect of sealing esophagus.Therefore use this throat breathing guide catheter and not only can keep respiratory passage unblocked, can also prevent that gastric content from backflowing, avoid mistake to inhale and take place.Breathe under the constant situation of the overall diameter of guide catheter at throat, reduce the diameter of esophageal catheter as far as possible, make the working place of airway pressure operation pipe big as far as possible, increased the convenience of operation.The present invention does not have the mechanicalness invasion and attack to vocal cords and tracheal mucosa, and mucosa blood does not influence the tracheal cilia motion, so can keep the air flue self-cleaning action for unaffected.And there are not vomiting, the worry of suction by mistake that laryngeal mask may exist.
This utility model is that the operation technique with ventilation and trachea, endoscopy of bronchus and trachea, bronchus inside combines.Not only make the more comfortable convenience of checking process, also increased safety coefficient greatly.Be particularly useful for the taking-up of children with tracheal foreign body and can not tolerate the Bronch patient of trachea under the local anaesthesia.Start new era of tracheascope operation.
