In order to improve the clinical application effect of intubating laryngeal mask airway, developed once the intubating laryngeal mask airway of three types: the first is Standard laryngeal mask airway, it also is at present clinical intubating laryngeal mask airway the most commonly used, the gas tube that basic structure has cover capsule, airway and inflates for covering capsule, be mainly used in keeping the respiratory tract function, therefore but can not carry out drainage procedure to esophagus, for laryngemphraxis, full stomach, the patient of fasting water, acute abdomen, Abdomen Trauma, drug intoxication and digestive tract hemorrhage should not use; The second is the Special laryngeal mask airway of guidance tracheal intubation, and this kind intubating laryngeal mask airway is a kind of improved device that designs for guiding insertion tracheal intubation specially, and it is the endotracheal tube of 9.0mm that maximum can be drawn slotting internal diameter; The third is ProSeal laryngeal mask airway, this kind intubating laryngeal mask airway can carry out drain to the esophageal reflux material, its basic structure is similar to the standard intubating laryngeal mask airway, just has a drainage tube parallel with breather, this drainage tube is by intubating laryngeal mask airway cover capsule and be opened on the tip of covering capsule, the tip can be blocked in patient's introitus oesophagi in use, thereby can attract esophageal reflux thing and gastric content by most advanced and sophisticated opening.
Application number is that 200620025407.0 utility model patent discloses a kind of Double-tunnel plastic throat mask, comprise that the airway that is embedded with reinforcing line in the shape of a spiral in the tube wall and one of far-end are ovate inflatable cover and consist of, inflatable cover is communicated with airway, described inflatable cover is by air bag seat, being hollow cylindrical air bag and connected knapsack consists of, also be designed with a food meatus parallel with airway in the inflatable cover, this food meatus one end passes knapsack and forms food meatus on the air bag top and exports, airway and food meatus middle part are designed with dismantled and assembled bite-block, and can fix by dismantled and assembled bite-block, the air bag outward flange is communicated with the inflation tubule, inflation indication capsule and check valve.
This utility model is provided with food meatus and adopts dismantled and assembled pressure pad that two pipes are fixing airway one side is parallel, makes it increase the esophagus passage in function, therefore except the foundation that guarantees the artificial airway, can also solve clinical in discharging the needs of gastric juice and extra-nutrition.
But there is following defective in this intubating laryngeal mask airway with drainage tube at present: (1) owing to being that multitube is set up in parallel, structure is complicated, and is easily mobile, has during insertion certain difficulty; (2) the inner a plurality of bodys of cover capsule intersect, and are manually bonding, complex process, and production efficiency is low; (3) need with a large amount of adhesive, the risk that comes off of coming unglued is arranged, the patient uses and has potential safety hazard.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can overcome defective of the prior art, has the esophagus drainage function, and simple for structure, and mounting process is simple, is convenient to the two-tube laryngeal mask that inserts during use.
For addressing the above problem, a kind of two-tube laryngeal mask of the present utility model comprises cover capsule, supporting member, breather, drainage tube and gas tube; Wherein, the cover capsule is provided with for the cavity of placing supporting member, the duckbill that the upper surface is slight arc convex for inner, its left end is provided with the esophagus connected entrance, be provided with the air flue connected entrance on the lower surface, right-hand member is provided with the running-on that is connected with supporting member, be provided with the inflation inlet that the cover capsule is inflated on its cavity inner wall, described supporting member extend into the inside of described cover capsule by this running-on; Be provided with separate ventilation tract, drain tract and inflation tract in the supporting member, described air flue connected entrance, esophagus connected entrance, inflation inlet are corresponding respectively to be connected with the breather that is arranged on independently of each other the supporting member right side, drainage tube and gas tube by ventilation tract, drain tract and inflation tract.
Stud with the screw type stainless steel silk in the tube wall of described breather.
Stud with the screw type stainless steel silk in the tube wall of described drainage tube.
Adopt the two-tube laryngeal mask of this utility model structure, compared with prior art have following beneficial effect: the overall structure that the cover capsule of (1) this two-tube laryngeal mask is formed in one, self does not need extra bonding process, has avoided the risk of coming unglued; (2) the multi-cavity road structure that adopts supporting member to be integrated makes this two-tube laryngeal mask structure simple and direct, takes up space little, and is more firmly easier than traditional ProSeal laryngeal mask airway in update; (3) each body is independent separately by tract, can use individually or simultaneously, and two-tube laryngeal mask can not be subjected to displacement at inflation back cover capsule, and can effectively form sealing at human body larynx position; This utility model is particularly useful for the rescue of omnibearing anaesthesia process and critical patient to be processed.
