Description
Technical field
The present invention relates to medical aid field, particularly the triple anti-error suction of a kind of weak stimulation can put gastrointestinal tract laryngeal mask by per nasal.
Background technology
Laryngeal mask is as apparatus that a kind of glottis is ventilated, and has been widely used in the airway management of anesthesia and first aid.But traditional laryngeal mask as the patent No. be 200920299927.4,200920157717.1 and 200710102366.X disclosed in Chinese patent still there is following problem:
1. because tongue body is distributed with abundant teleneuron, especially at tongue Rolandic fissure and sulcus terminalis place, the distribution of teleneuron is more concentrated, therefore tongue Rolandic fissure and sulcus terminalis is stimulated can to cause strong nauseating discomfort, uvula is also distributed with abundant teleneuron, therefore stimulates uvula also can cause strong nauseating discomfort.The lingual surface part of traditional laryngeal mask is just pressed in the middle of tongue body, and the position of the middle of tongue body tongue Rolandic fissure and sulcus terminalis just, and the jaw face portion of laryngeal mask is just pressed in uvula, the teleneuron abnormal distribution of these positions enriches, strong to irritant reaction, so insert traditional laryngeal mask, patient feel sick discomfort be difficult to tolerance.
2. traditional laryngeal mask cover capsule back side is full smooth, and after inserting laryngeal mask, very difficult per nasal inserts stomach tube or duodenal feeding tube.
3., though traditional two-tube laryngeal mask is designed with an attraction pipeline, attraction pipeline is arranged in laryngeal mask, and tube chamber is less, easily blocks.
Summary of the invention
The invention provides the triple anti-error suction of a kind of weak stimulation and can put gastrointestinal tract laryngeal mask by per nasal, reduce the stimulation to patient's pars oralis pharyngis, patient is more easily tolerated.
The technical solution used in the present invention is:
The triple anti-error suction of weak stimulation can put gastrointestinal tract laryngeal mask by per nasal, comprise laryngeal mask body, laryngeal mask cover capsule, bite-block, breather line, breather line interface, breather line opening, attraction pipeline, attraction pipeline opening, tongue fovea centralis, recessed and the catheter groove of uvula, bite-block is arranged on above laryngeal mask body, laryngeal mask cover capsule is arranged on below laryngeal mask body, breather line interface is arranged on above bite-block, in laryngeal mask body, to be provided with uvula recessed at the epimere back side, uvula is recessed extends for catheter groove naturally through the laryngeal mask cover capsule back side, laryngeal mask body front central authorities are provided with tongue fovea centralis, breather line opening is arranged in laryngeal mask cover capsule, attraction pipeline opening is arranged on the rear flank wall of catheter groove end, attraction pipeline penetrates above laryngeal mask body, come downwards to attraction pipeline opening through laryngeal mask body to communicate with catheter groove.Attraction pipeline and breather line run in the guide tongue fovea centralis and the recessed both sides of uvula through the part of laryngeal mask body.
Further, also comprise slope, slope is separately positioned on bite-block and tongue fovea centralis junction and bite-block and the recessed junction of uvula.
Preferably, also comprise esophagus convex, esophagus is convex is arranged on laryngeal mask cover capsule lower end, for laryngeal mask cover capsule is to the continuity in esophagus entrance.
Preferably, the convex length of esophagus is 1-2cm.
Preferably, laryngeal mask body surface parcel medical silica-gel or medical elastomer.
Preferably, laryngeal mask cover capsule adopts shore hardness to be that the medical silica-gel of 0-15 or medical elastomer are made.
Preferably, the triple anti-error suction of weak stimulation can be put gastrointestinal tract laryngeal mask and adopts silver ion or titanium dioxide or hydroxyapatite or bioactive molecule to carry out antibacterial bacteriostatic process by per nasal, or adopts layer upon layer electrostatic self-assembling technique to carry out antibacterial bacteriostatic process to laryngeal mask.
Preferably, the triple anti-error suction of weak stimulation can be put gastrointestinal tract laryngeal mask and stretches into mouth, pharynx, the radian of throat portion and human body mouth, pharynx, larynx and dissect radian and adapt by per nasal, is 90 ~ 120 degree.
Laryngeal mask cover capsule can be both non-inflatable cover capsule, also can be inflated type cover capsule.
The invention has the beneficial effects as follows:
1, laryngeal mask body surface parcel medical silica-gel or medical elastomer, soft flexible, is inserting in process and little to the damage of pars oralis pharyngis soft tissue after inserting.
2, laryngeal mask cover capsule quality is soft, can be automatically moulding with the anatomic form of human body bottleneck throat after inserting, little to the damage of pars oralis pharyngis soft tissue.
3, to arrange uvula recessed for laryngeal mask body, uvula can be maked somebody a mere figurehead, make laryngeal mask not oppress uvula, alleviate staphyleus stimulation.
4, laryngeal mask body arranges tongue fovea centralis, tongue Rolandic fissure can be maked somebody a mere figurehead, and makes laryngeal mask not oppress tongue Rolandic fissure, alleviates the stimulation to tongue Rolandic fissure.
5, after inserting laryngeal mask, esophagus to protrude in esophagus entrance and is close to esophagus antetheca, both can fixed cover capsule position, can reduce again the generation of backflowing and inhaling by mistake.This is the first heavy anti-error suction.
6, catheter groove is connected with esophagus, be equivalent to esophagus on prolong part.When per nasal inserts gastrointestinal tract, gastrointestinal tract passes through choana, falls into catheter groove, is directed in esophagus along catheter groove.In addition, when esophageal reflux thing is many, the thing that backflows also can be attracted totally in this groove upstream entrance cavity and nasal cavity, and under glottis can not be flowed in trachea.This is the second heavy anti-error suction.
7, attraction pipeline can attract oropharyngeal secretions and the thing that backflows backflowed to esophagus entrance, reduces the generation of by mistake inhaling.This is triple anti-error suction.
