Abstract
An anti-backflow minitype nasopharynx laryngeal mask relates to the field of medical treatment and consists of two parts, namely, an anti-backflow esophagus tube with double pouches and a minitype nasopharynx laryngeal mask. The anti-backflow esophagus tube with double pouches is provided with an esophagus pouch and an oral pharynx pouch, wherein the esophagus pouch is arranged at the upper end of the anti-backflow esophagus tube with double pouches; the oral pharynx pouch is arranged below the anti-backflow esophagus tube with double pouches, away from the esophagus punch by 10cm; the esophagus pouch is a 360-degree high-capacity low-pressure pouch; and the oral pharynx pouch is a flat pouch with wraps at two sides and a tongue surface. Without changing the operating habits of anesthetists, superior laryngeal ventilation can be realized by blind nasotracheal intubation, the problem of type matching can be solved by one-time operation, and in case of an emergency, fast endotrachael intubation can be realized to improve the anesthesia safety.
Description
Technical field:
This utility model relates to medical field, is specifically related to a kind of anti-miniature laryngeal mask of formula nasopharynx that backflows.
Background technology:
In clinical anesthesia for solve complication that endotracheal intubation causes especially the compressing damage of vocal cords and tunica mucosa tracheae invented laryngeal mask airway, but existing laryngeal mask all is that insert volume from the oral cavity very big, often, model need not change insertion repeatedly because of matching, bring very inconvenience and easily cause the bottleneck throat damage to clinical manipulation, postoperative pharyngalgia incidence rate is also very high.It has also changed Anesthetist's traditional operation custom, and can not realize fast that laryngoscope photopic vision intubate is set up and stablize air flue in that emergency is little, has greatly increased the misgivings of Anesthetist to secure context.
The utility model content:
The purpose of this utility model provides a kind of anti-miniature laryngeal mask of formula nasopharynx that backflows, it can be ventilated on the blind slotting realization larynx of per nasal under the situation that does not change Anesthetist's operating habit, and once solve the model matching problem, can realize that in case of emergency quick endotracheal intubation improves the anesthesia safety.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it is made up of anti-food meatus 1 and miniature laryngeal mask 2 two parts of nasopharynx of backflowing of the two capsules of band; The anti-food meatus 1 that backflows of the two capsules of band is provided with oesophageal pouches 1-1 and oropharynx capsule 1-2, oesophageal pouches 1-1 is arranged on the front end of the anti-food meatus 1 that backflows of the two capsules of band, oropharynx capsule 1-2 is arranged on the anti-10cm place of food meatus 1 apart from oesophageal pouches 1-1 of backflowing of the two capsules of band, oesophageal pouches 1-1 is the high low pressure capsules that hold of 360 degree, and oropharynx capsule 1-2 is that both sides and lingual surface have the flat capsule that holds.
The anti-food meatus 1 that backflows of the two capsules of described band mainly drains gastric juice outside the oral cavity by esophagus, avoids mistake to inhale; Its front end is bullet-shaped and has big side opening that inwall is provided with two ductules, realizes the inflation and the venting of the two capsules of food meatus respectively.
Described oesophageal pouches 1-1 shutoff esophagus prevents the gastric juice oral cavity of backflowing; Oropharynx capsule 1-2 shutoff mouth and nose chamber, when the laryngeal mask capsule of the miniature laryngeal mask 2 of nasopharynx fully when shutoff mouth and nose chamber and choana, oropharynx capsule 1-2 also can participate in assisting shutoff mouth and nose chamber together, thereby has solved the unmatched problem of the miniature laryngeal mask model of nasopharynx.
This utility model is united use by being with anti-food meatus 1 and the miniature laryngeal mask 2 of nasopharynx of backflowing of two capsules, can on the blind slotting realization larynx of per nasal under the situation that does not change Anesthetist's operating habit, ventilate, and once solve the model matching problem, can realize that in case of emergency quick endotracheal intubation improves the anesthesia safety.
Description of drawings:
Fig. 1 is the structural representation of the anti-food meatus 1 that backflows of the two capsules of band;
Fig. 2 is the structural representation of the miniature laryngeal mask 2 of nasopharynx.
The specific embodiment:
Referring to Fig. 1-2, this specific embodiment by the following technical solutions: it is made up of anti-food meatus 1 and miniature laryngeal mask 2 two parts of nasopharynx of backflowing of the two capsules of band; The anti-food meatus 1 that backflows of the two capsules of band is provided with oesophageal pouches 1-1 and oropharynx capsule 1-2, oesophageal pouches 1-1 is arranged on the front end of the anti-food meatus 1 that backflows of the two capsules of band, oropharynx capsule 1-2 is arranged on the anti-10cm place of food meatus 1 apart from oesophageal pouches 1-1 of backflowing of the two capsules of band, oesophageal pouches 1-1 is the high low pressure capsules that hold of 360 degree, and oropharynx capsule 1-2 is that both sides and lingual surface have the flat capsule that holds.
The anti-food meatus 1 that backflows of the two capsules of described band mainly drains gastric juice outside the oral cavity by esophagus, avoids mistake to inhale; Its front end is bullet-shaped and has big side opening that inwall is provided with two ductules, realizes the inflation and the venting of the two capsules of food meatus respectively.
Described oesophageal pouches 1-1 shutoff esophagus prevents the gastric juice oral cavity of backflowing; Oropharynx capsule 1-2 shutoff mouth and nose chamber, when the laryngeal mask capsule of the miniature laryngeal mask 2 of nasopharynx fully when shutoff mouth and nose chamber and choana, oropharynx capsule 1-2 also can participate in assisting shutoff mouth and nose chamber together, thereby has solved the unmatched problem of the miniature laryngeal mask model of nasopharynx.
This specific embodiment is united use by being with anti-food meatus 1 and the miniature laryngeal mask 2 of nasopharynx of backflowing of two capsules, can on the blind slotting realization larynx of per nasal under the situation that does not change Anesthetist's operating habit, ventilate, and once solve the model matching problem, can realize that in case of emergency quick endotracheal intubation improves the anesthesia safety.
