Description

The two capsule laryngeal masks of esophageal obstruction formula

Technical field

This utility model relates to a kind of medical apparatus and instruments of the artificial airway's of foundation ventilation, the two capsule laryngeal masks of particularly a kind of esophageal obstruction formula.

Technical background

Laryngeal mask is set up the medical apparatus and instruments of artificial airway's ventilation as a kind of patient who is used for surgery anesthesia, critical patient rescue or other assisted respiartion, especially stop suddenly for heart beating and the inconvenient patient of intubate to use be very suitable, obtained at present using widely.Because the recovery initial stage is kept the unobstructed of air flue, give the patient with more competent oxygen confession, be vital for the recovery success or not.Use laryngeal mask then to help keeping the unobstructed of air flue, and do not need special position, easy and simple to handle rapid, can race against time, save patient's life.

According to the different clinical applications of laryngeal mask, being divided into is three kinds of fundamental types: 1, standard type laryngeal mask is at present clinical intubating laryngeal mask airway the most commonly used, by covering capsule, airway and being used to the gas tube of cover capsule inflation to constitute.Therefore be mainly used in keeping of respiratory tract, but it can not carry out drainage procedure to esophagus, for laryngemphraxis, full stomach, the patient of fasting water, acute abdomen, Abdomen Trauma, drug intoxication, digestive tract hemorrhage should not use.

2, the special-purpose laryngeal mask of guidance tracheal intubation, this kind intubating laryngeal mask airway are a kind of improved devices that relates to for guiding insertion tracheal intubation specially, and it is the endotracheal tube of 9.0mm that maximum can be drawn slotting internal diameter.

3, esophagus conduction type intubating laryngeal mask airway, this kind intubating laryngeal mask airway can have drainage to the esophageal reflux material, its basic structure is similar to the standard laryngeal mask, just has a drainage tube parallel with breather, this drainage tube is by laryngeal mask cover capsule and be opened on the tip of covering capsule, in use the tip can be blocked in patient's introitus oesophagi, thereby can attract esophageal regurgitation thing and gastric content by most advanced and sophisticated opening.

Summary of the invention

The purpose of this utility model, be on the basis of standard type laryngeal mask, to improve, and design the two capsule laryngeal masks of a kind of esophageal obstruction formula, this cover capsule Front-end Design has one to be used to stretch into esophagus also can block esophagus after inflation occlusion balloon, product is when normal the use, when after the cover capsule inflation with the throat sealing and when forming the artificial airway, the sealing sacculus is with esophageall obstruetion, can play the effect that prevents the anti-stream of esophagus material, simultaneously can also carry out drain and decompression to the anti-material that flows of gastric by the perforate of sacculus front end, it is safe in the standard type laryngeal mask.

This utility model for achieving the above object, the technical scheme that is adopted is: the two capsule laryngeal masks of a kind of esophageal obstruction formula is characterized in that: its structure is by the cover capsule, occlusion balloon, breather, machine end joint, gas tube, pilot balloon, Non-return air valve, relief pipe, 9 building blocks of relief pipe joint are formed, and the structure of wherein said each parts is: described cover capsule, and its contour structures shaped design is an oval, the lower end has a passage, is provided with a relief chamber in the cover capsule; Described occlusion balloon, its contour structures shaped design are wherein any shape of sphere, elliposoidal, cylindrical, taper, truncated cone-shaped, or any other solid geometry shape, and it is arranged on the front end of cover capsule, and the occlusion balloon front end has a vent; Described breather, it is connected with cover capsule rear end, and breather is one the body of certain radian to be arranged, and this radian is spent between 180 degree 90; Design has a relief passage and an airway in the breather, have a relief passage hole on the breather outer wall, an end of relief passage communicates with relief chamber, and the other end communicates with the relief passage hole, one end of airway communicates with passage, and the other end connects a machine end joint; Described relief pipe, it places in the cover utricule, and an end of relief pipe communicates with relief chamber, and the other end and relief pipe joint join, and the other end of relief pipe joint and occlusion balloon inwall join, and the inner chamber of its relief pipe joint communicates with vent; Described gas tube, one end connect the cover capsule, and the other end connects pilot balloon or pressure indicator, and the other end of pilot balloon connects Non-return air valve.
