Vent hood on multifunction throat

Technical field

The present invention relates to vent hood on a kind of multifunction throat.

Background technology

Tracheal intubation is a kind of very safe respiration channel method for building up, but is difficult to avoid the difficult intubation of a variety of causes and tracheal intubation to operate defects such as patient's strong impulses.After Britain Anesthetist Brain in 1981 has invented the standard intubating laryngeal mask airway and formally put goods on the market in 1988, the management of respiratory tract has just entered brand-new epoch.Laryngeal mask is a kind of patient to be stimulated to very micro-and airway pressure device on larynx safely and effectively, can set up a respiration channel for patient quickly and easily.Rely on its outstanding representation when processing common and difficult airway, the national laryngeal mask of some of the U.S., West Europe has replaced the unimpeded medical apparatus and instruments of maintenance air passage that tracheal intubation becomes main flow.The major complications that laryngeal mask is used is suffocate and miss suction.Have and report that in use laryngeal mask art, the incidence rate of anti-stream can be up to 25% on a small quantity.So reflux erroneous aspiration and the problem of suffocating that the solution a variety of causes causes have become the critical index that determines following larynx mo(u)ld top half breather quality.

Summary of the invention

The object of the invention is to: design vent hood on a kind of multifunction throat that more can give prominence to breather superiority on larynx.It is reached: operation is convenient, less to patient's zest, more effective reflux erroneous aspiration and the airway obstruction of preventing of energy succinctly; Also can, under the prerequisite that does not affect patient's ventilation, carry out the purpose such as inspection and other operations in larynx, trachea.

Specific implementation of the present invention is: be by esophagus drainage channel, secretions collection attraction channel, secondary airway, each separating devices such as operation designated lane, high seal air bag and cover body shell are successfully developed, and organic assembling, stack or combination function with them, reach goal of the invention.The esophagus drainage channel is positioned at a side of ventilation pipeline section and cover body section, and form the part of their sidewalls, its front end is provided with the airtight air bag of esophagus and inserts esophagus, can prevent vent hood displacement on larynx and stop up glottis, accurately entering of bootable stomach tube or gastroscope, reach initiatively decompression drainage antireflux and the convenient purpose checked simultaneously; The airtight air bag of esophagus after the inflation thing that can effectively prevent from backflowing enters and stimulates pharyngeal cavity and trachea, causes mistake inhale and choke and cough, and also can prevent that gas from entering gastric, causes flatulence.Secretions is collected the opposite side that attraction channel is positioned at ventilation pipeline section and cover body section, and form the part of their sidewalls, integral body has collection, storage, attracts liquid functional, can effectively prevent dynamically that throat secretions and blood from entering trachea, cause airway obstruction and stimulate trachea to cause to choke and cough, reduce the generation of aspiration pneumonitis and choke and cough the stress caused.The cover body section that secondary airway and esophagus drainage channel and secretions are collected attraction channel forms faceshield side wall jointly, and front end enters in breather, can effectively prevent that epiglottis obstruction breather from exporting can not ventilating of causing.The high seal air bag of the high appearance of the low pressure of cover body rear end can be raised the root of the tongue, promote epiglottis, prevent the outlet of epiglottis obstruction breather, can expose larynx week and glottis, fully appear surgical field of view, facilitate the patient to carry out in larynx and trachea checking operation, the obstruction in the time of also can reducing endotracheal tube and enter; Can effective airtight pharyngeal cavity, allow incidence that larger range of activity is arranged, and still can keep normal ventilation.Be attached to the cover body shell in esophagus drainage channel and the suction catheter passage outside, there is filling, airtight pharyngeal cavity effect.The operation designated lane separates with the breather end fitting, can, under the prerequisite do not affected patient's ventilation, facilitate the patient to carry out in larynx and trachea checking operation; Can by the operation designated lane insert suction catheter and secretions collect together with attraction channel attract relatively large hemorrhage, thereby realize that the minimizing mistake of larger limit inhales, and can fully appear surgical field of view; Overseas cap above the operation designated lane, have airtight airway, and the anti-gas-leak effect, raise overseas cap and can insert the endotracheal tube than large diameter, to ensure patient's normal ventilation; 2 ~ 3 handle holes are set on overseas cap, the anti-ease valve of the external leakage of gas-tight is arranged in it.Establish a rotatable interface above the gullet drainage tube end with below gathering hole, facilitating the patient to stand in the relatively-stationary contradiction of change and instrument position that diverse location was operated and solved the patient body position.Inserting the design of guide uses, blurt out the easily physiological bending of pharynx, laryngopharynx section of the front end that can make larynx mo(u)ld top half vent hood arrives accurate location smoothly, reduce stimulation and damage that rough operation causes, can prevent that on larynx, vent hood is inserted the crooked obstruction glottis that gives a discount of front end in process simultaneously; Through operation designated lane tracheal intubation the time, insert the effect that guide also has the pushing and withstanding endotracheal tube, facilitate vent hood to exit oral cavity.
