Abstract
The utility model relates to a non-tracheal intubation catheter appliance used for general anesthesia, in particular to a bendable laryngeal mask that has high safety and few complications. The bendable laryngeal mask adopts the technical scheme as follows: the bendable laryngeal mask consists of a joint, a ventilation catheter, an indicating sacculus, an aerating valve, an aerating pipe and a mask bursa; one end of the ventilation catheter is connected with the mask bursa, and the other end of the ventilation catheter is connected with the joint; and one end of the aerating pipe is connected with the mask bursa, and the other end of the aerating pipe is connected with the indicating sacculus and the aerating valve respectively. The bendable laryngeal mask has the benefits that the bendable laryngeal mask and the cataposis lacuna can generate a better airtight effect, and the position of the laryngeal mask at the hypopharynx can not be affected even when a ventilation ducts deviates from the central line, so that the safety is greatly improved, and the application scope is obviously enlarged.
Description
One, technical field:
The non-tracheal intubation catheter apparatus that this utility model uses when relating to a kind of general anesthesia, particularly a kind of safe, bending type laryngeal mask that complication is few.
Two, background technology:
Laryngeal mask is the novel anesthesia utensil of keeping air flue that integrates face shield and tracheal intubation advantage as breather on the glottis, is most important invention during nearly 30 years air flues are kept.Have easy and simple to handle, the mechanical irritation of no larynx and trachea, hemodynamics and intraocular pressure are relatively stable, complication is few, can keep effectively, ventilate reliably, and can be used for difficult intubation, it is reported that the existing patient more than 100,000,000 in the whole world uses, and do not have the report that directly causes death.At present the problem that exists is: cause covering capsule with bottleneck throat is airtight not tight through regular meeting, gas leakage and laryngeal mask snorkel can not bendings easily, influence its safety and range of application.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of security performance height, the bending type laryngeal mask of applied range.
Its technical scheme is: be made up of joint, airway, indication sacculus, charge valve, gas tube, cover capsule, airway one end connects the cover capsule, and other end jointing, an end of gas tube connect the cover capsule, and the other end connects indication sacculus and charge valve respectively.
Above-mentioned airway includes the steel wire of structure of steel wire body in three sections, can be arbitrarily crooked.
The beneficial effects of the utility model are: the bending type laryngeal mask can with swallow lacuna and produce better obturation effect, even departing from center line, airway do not influence laryngeal mask in the hypopharynx position yet, safety improves greatly, range of application also significantly enlarges, can only the operation of general anesthesia tracheal intubation also can use the bending type laryngeal mask now in the past, realize ventilation, as: the operation on the path, otorhinolaryngologic operation etc. breathed.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of cover mouth;
Among the last figure: joint 1, steel wire body 2, airway 3, indication sacculus 4, charge valve 5, gas tube 6, cover capsule 7, cover mouth 8.
Five, the specific embodiment:
1-2 in conjunction with the accompanying drawings, the utility model will be further described:
This utility model mainly is made up of joint 1, steel wire body 2, airway 3, indication sacculus 4, charge valve 5, gas tube 6, cover capsule 7, airway 3 one ends connect cover capsule 7, other end jointing 1, one end of gas tube 6 connects cover capsule 7, the other end connects indication sacculus 4 and charge valve 5 respectively, described airway 3 includes three sections steel wire bodys 2, in structure of steel wire is arranged, can be arbitrarily crooked.
During use, laryngeal mask is put into pharyngeal, the cover mouthful 8 lucky atrium of larynx of aiming at the below, charge into proper amount of gas for indication sacculus 4 by charge valve 5, gas along gas tube 6 to the cover capsule 7, cover capsule 7 is filled and is swallowed lacuna, produce good obturation effect, the laryngeal mask back side is airway 3, and airway 3 includes 3 sections steel wire bodys 2, in have steel wire to reinforce, can be arbitrarily crooked, airway 3 extends to the oral cavity from the porous dehiscence of laryngeal mask central authorities always and is connected with joint 1, and joint 1 links to each other with reservoir bag or anesthetic machine breathing circuit again, realizes ventilation.Steel wire body 2 can be arbitrarily crooked, therefore can with swallow lacuna and produce better obturation effect, even departing from center line, airway do not influence laryngeal mask in the hypopharynx position yet, leak gas when preventing mechanical ventilation, safety improves greatly, and range of application also significantly enlarges, can only the operation of general anesthesia tracheal intubation also can use the bending type laryngeal mask now in the past, realize ventilation, as: the operation on the path breathed, otorhinolaryngologic operation etc.
Claims (2)
