For solving as above disappearance, the eighties in 20th century, British Brian has proposed the notion of laryngeal mask.Initial laryngeal mask, its structure is: the silicones laryngeal mask air bag, that comprises an inflatable leaves shape is used for the laryngeal mask snorkel that the gas tube and of silicones laryngeal mask airbag aeration is connected with silicones laryngeal mask air bag.Behind its insertion bottleneck throat, give the laryngeal mask airbag aeration, expansible laryngeal mask air bag can hold and seal epiglottis and glottis, forms the annular seal space of a low pressure around larynx, and the laryngeal mask connection tube leads to and can link to each other with respirator outside the oral cavity, but autonomous respiration or positive airway pressure.This kind laryngeal mask is compared with tracheal intubation, though technology easy master the gastric juice mistake of backflowing more in use can occur and inhale.Given this; The insider is arranged again; Esophagus conduction type laryngeal mask has appearred in improvement again on the basis of above-mentioned laryngeal mask, and the characteristics of this laryngeal mask are: increase the esophagus drainage tube that parallels with laryngeal mask snorkel, can insert suction catheter esophageal reflux thing and gastric content are carried out drain; Perhaps carry out artificial enteral nutritional support where necessary, so just increased the safety in utilization of laryngeal mask.But this kind laryngeal mask relatively is suitable for the inspection of gastrointestinal and other positions; When this kind laryngeal mask is used for bronchoscopy; Insert branchofiberoscope inspection through laryngeal mask snorkel,, therefore have following shortcoming: on the one hand because microscopy and airway are shared; Increase airway resistance, influence sufferer safety; On the other hand, for keeping sufferer blood oxygen saturation, Anesthesia Department such as need confirm the permission of sufferer oxygenation status, just can let gas off-take, are checked by the examiner, thus, increase review time and clinical risk.In view of as above defective, it is imperative to invent the special-purpose laryngeal mask of a kind of bronchus.
The utility model content
This utility model provides a kind of airway resistance little for the deficiency that solves prior art, the special-purpose laryngeal mask of the bronchus that the review time is short and clinical risk is little.
This utility model is realized through following technical scheme: the special-purpose laryngeal mask of bronchus; Comprise that an inflatable laryngeal mask air bag, is used for the laryngeal mask snorkel that the gas tube and to the laryngeal mask airbag aeration is connected with the laryngeal mask air bag; Described laryngeal mask air bag is connected with an end end of laryngeal mask snorkel; It is characterized in that: described laryngeal mask air bag also is connected with an inspection pipeline parallel with laryngeal mask snorkel; Described inspection pipeline one end end is connected with the laryngeal mask air bag, and other end end is provided with and can makes it become the screw-cap of sealing state.
As a kind of improvement of this utility model, be provided with the spiral wire that can make laryngeal mask snorkel become distorted shape in the described laryngeal mask snorkel.
As improving again of this utility model, on described laryngeal mask snorkel, be provided with the bite-block of outstanding pipe face, bite-block can prevent patient when inspection, break by the teeth laryngeal mask snorkel or inspection pipeline.
As improving again of this utility model; Be connected with a screw-cap at described laryngeal mask airway tube end, like this, laryngeal mask snorkel also can be used as the inspection pipeline; Need not to distinguish is laryngeal mask snorkel or inspection pipeline; Wherein one as laryngeal mask snorkel, and just as the inspection pipeline, vice versa for another one.
The beneficial effect that this utility model is obtained: the special-purpose cover of the bronchus of this utility model; On the laryngeal mask air bag, connect an inspection pipeline parallel with laryngeal mask snorkel, like this, bronchoscope can need not and laryngeal mask snorkel people having a common goal through inspection pipeline entering patient bronchus; Avoided robbing altogether the problem of air flue; Not only airway resistance is little, and the review time lacks and effectively shortens sufferer and do not have duration of ventilation, and clinical risk is little.
