Abstract

A drainage laryngeal mask comprises a mask bag, a main tube and a gas filling tube. An aerating cavity and a draining cavity are arranged in the main tube, the aerating cavity is communicated with an aerating hole on the mask bag, the tail end of the draining cavity extends out of the main tube to be arranged at the tail of a small end of the mask bag, a bending angle of the main tube ranges from 70 degrees to 100 degrees, and the section of the tail of the small end of the mask bag is elliptical. The drainage laryngeal mask brings convenience for medical staff to operate, reduces suffering of a patient and is good in sealing property, and gas is prevented from entering the esophagus of the patient to aggravate reflux of the stomach of the patient when gas flows through a catheter of the trachea of the patient.

Description

The conduction type laryngeal mask

Technical field

The present invention relates to a kind of medium is imported in the human body or is passed to the apparatus on the human body, relate to a kind of trachea specifically and use intubate.

Background technology

Laryngeal mask is Brain in the nineteen eighty-three invention and at first advocates use a kind of and adopt the device that mode is ventilated outside the glottis; In order to improve the clinical application effect of laryngeal mask; Present existing three types laryngeal mask: first kind is the standard type laryngeal mask, also is at present clinical laryngeal mask the most commonly used, and basic structure has cover capsule, airway and is the gas tube of cover capsule inflation; Be mainly used in and keep the respiratory tract function, can not carry out drainage procedure; Second kind is the special-purpose laryngeal mask of guidance tracheal intubation; The third is the conduction type laryngeal mask; Except being used to keep the respiratory tract function, also be used for the esophageal regurgitation material is carried out drain, similar is in common laryngeal mask; Just increased a drainage lumens parallel with venting cavity; Drainage lumens is through the cover capsule and be opened on the tip of cover capsule, most advanced and sophisticatedly in use can stop up esophagus, and will instead flow thing and stomach carries out drain through opening.But present this conduction type laryngeal mask does not match owing to being responsible for flexibility and human oral cavity esophagus flexibility; There is operational inconvenience in use, in the operation process, is difficult to insert; Even if insert swimmingly; Do not match because of being responsible for flexibility and esophagus, it is uncomfortable to cause patient's throat to produce through regular meeting, increases patient's misery.

Summary of the invention

The purpose of this invention is to provide a kind of conduction type laryngeal mask, its more convenient patient's esophagus that in operation process, inserts reduces the painful of patient and can avoid that stomach is counter to flow because of gas leakage causes.

To achieve these goals; Technical solution of the present invention is: a kind of conduction type laryngeal mask, comprise cover capsule, the person in charge, gas tube, and be provided with venting cavity and drainage lumens in the person in charge; Venting cavity is communicated with the passage of cover on the capsule; The end of drainage lumens stretches out is responsible for the end that places cover capsule small end, and the said person in charge's angle of bend is 70 degree-100, and the terminal cross sectional shape of cover capsule small end is oval.

Conduction type laryngeal mask of the present invention, wherein, the cross sectional shape of the conduction hole that said drainage lumens is terminal is oval.

Conduction type laryngeal mask of the present invention, wherein, the said person in charge's bending angle is 90 degree.

Conduction type laryngeal mask of the present invention; Wherein, said cover capsule comprises first, second utricule, and said passage is located at the first utricule abdominal part; Said second utricule is arranged at the first utricule back; The inner chamber of the inner chamber of said second utricule and first utricule is interconnected, and second utricule is the circular arc of outwards protruding from the back of first utricule, and said person in charge's end is connected on said first utricule.

Conduction type laryngeal mask of the present invention, wherein, said passage comprises first, second passage, is provided with boss between said first, second passage.

Conduction type laryngeal mask of the present invention, wherein, the said person in charge's free end is provided with joint, and the joint outer wall is provided with bayonet socket, and the body of said gas tube is fastened in the said bayonet socket.

Conduction type laryngeal mask of the present invention, wherein, the inflation end of said gas tube comprises union joint and pilot balloon, pilot balloon is located between the body of union joint and gas tube, is provided with vent valve between union joint and the pilot balloon.

After adopting such scheme, the bending angle that conduction type laryngeal mask of the present invention is responsible for is 70 degree-100 degree, after laryngeal mask inserts esophagus; The person in charge is complementary with oral cavity esophagus bending angle, when making things convenient for the medical worker to operate, reduces the patient suffering; And after laryngeal mask inserts the human body esophagus fully, coincide owing to be responsible for human body esophagus bending degree, laryngeal mask is close to the human oral cavity wall; Sealing is stronger, be more conducive to flow thing and stomach carries out drain with counter, and the cross sectional shape of conduction type laryngeal mask small end is oval; More identical with the planform of human body esophagus, be easy to airtight esophagus, having avoided airway tube when ventilation gas to get into the esophagus aggravation, stomach is counter flows.

In addition, the conduction hole cross sectional shape is oval, during drain between slotted eye meeting and the stomach tube two ends leave the gap to play decompressing effect, be convenient to drain.

The cover capsule also comprises second utricule; Second utricule is a circular arc; Therefore it is better with the sealing property of human body bottleneck throat to cover capsule inflation back, prevents to flow because of gas leakage causes that stomach is counter, and first, second utricule inner chamber is interconnected; Once inflation can make first, second air bag fill simultaneously successively, uses more convenient.

First utricule of cover capsule is provided with two passages, so ventilatory effect is better, is provided with boss between two passages, and when the patient that the bottleneck throat soft tissue is loose used, soft tissue was resisted against on the boss, avoids stopping up passage.

The joint of being responsible for is provided with bayonet socket, and the body of gas tube embeds in the bayonet socket and reaches fixed effect, and is simple to operate, avoids the gas tube end to get into the patient oral cavity in the use, and is safer.

The inflation end of gas tube is provided with vent valve and pilot balloon, therefore can fast the gas in the cover capsule be emitted after the operation, and in the deflation course, judge the volume of rest gas in the cover capsule through pilot balloon, and is more directly perceived.
