The utility model provides a laryngeal mask, as shown in figure 1, this laryngeal mask is including breathing mask 1, trunk line 2, gas tube 3 and inflation valve 4, trunk line 2 one end with breathing mask 1 connects, the both ends of inflation tube 3 respectively with breathing mask 1 with inflation valve 4 connects, wherein, the intraductal space of the other end of trunk line 2 is cut apart into first cavity 5 and second cavity 6, follows first cavity 5 and second cavity 6 extend first branch pipe 7 and second branch pipe 8 respectively.
The utility model discloses in, inflation valve 4 passes through inflation tube 3 to aerify in the ventilation hood 1, the bronchoscope passes through first branch pipe 7 inserts the no cavity pipeline that enters main pipeline 2 behind first cavity 5, second branch pipe 8 can be connected with breathing machine or other oxygen supply unit, and oxygen is by the no cavity pipeline that second branch pipe 8 entered main pipeline 2 behind second cavity 6. Bronchoscope and oxygen sneak into same pipeline again behind different branch pipes and cavity respectively, can be furthest avoid leaking gas, guarantee sufficient oxygen suppliment pressure, guarantee patient's oxygen supply, avoid carbon dioxide to accumulate.
According to a preferred embodiment of the present invention, the first branch 7 communicates with the first chamber 5 in a straight line. In this preferred embodiment, the bronchoscope can be inserted more conveniently.
In the present invention, there is no special limitation on the lengths of the first chamber 5 and the second chamber 6, as long as the technical effects of the present invention can be achieved, but in order to further ensure the oxygen supply and avoid the air leakage and carbon dioxide accumulation, preferably, the lengths of the first chamber 5 and the second chamber 6 are 1/3-2/3 of the total length of the main pipe 2.
The utility model discloses in trunk line 2 gets into the entry upper portion of ventilation hood 1 preferably is provided with perpendicular fence 9. The vertical fence 9 is arranged to form a longitudinal slit to prevent the epiglottis from blocking the main conduit 2.
The utility model discloses in, preferably, the material at the nearly tooth position of trunk line 2 is the duroplasts, the periphery of duroplasts still is provided with soft glue film 10. In the preferred embodiment, the hard plastic is capable of supporting the bronchoscope without being easily deformed; the soft gel layer 10 can prevent the teeth from being put on and the oral cavity from being damaged.
In the present invention, the soft glue is a relatively soft glue compared with the hard glue, for example, the soft glue is polyethylene and/or polypropylene.
In the present invention, the hard plastic may be a conventional choice in the art, for example, the hard plastic is at least one of a phenolic plastic, a polyurethane plastic, an epoxy plastic, an unsaturated polyester plastic and a furan plastic.
