Setting by check (non-return) valve 7, it is possible to be effectively prevented the generation of gas backflow phenomenon.
Specifically, for the ease of the control to the gas amount of being inflated in cuff 3, this utility model embodiment provides
In laryngeal mask, as shown in Figure 4 and Figure 5, pilot balloon 8 can be provided with between above-mentioned check (non-return) valve 7 and cuff 3, and this pilot balloon 8 can
Arrange at check (non-return) valve 7 to close on.The gas flow in cuff 3 can be demonstrated exactly, therefore by instruction due to pilot balloon 8
The setting of air bag 8, it is possible to exactly the gas inflated amount in cuff 3 is controlled, thus is effectively improved comprehensively making of laryngeal mask
Use performance.
Preferably, in order to ensure laryngeal mask foreign sense during indwelling in human body pharyngeal cavity, and yet further reduce laryngeal mask pair
The damage of Oropharynx mucosa, in the laryngeal mask that this utility model embodiment provides, above-mentioned vent stack 2, cuff 3 and gas tube 6
Silica gel material is used to make to be preferably.Owing to silica gel material is preferable, therefore by silica gel material with the compatibility of human body and affinity
Vent stack 2, cuff 3 and gas tube 6 that matter is made are when people's intracorporeal indwelling, it is possible to realize foreign sense, and to Oropharynx mucosa
Damage be preferably minimized such that it is able to the treatment effectively alleviating patient is painful.
It should be added that herein, in the laryngeal mask that this utility model embodiment provides, vent stack 2 can also overlap
Being provided with bite-block (not shown), this bite-block can close on gas outlet 31 and arrange, in i.e. bite-block should be arranged on patient oral cavity and right
Answer the position at tooth；Further, above-mentioned bite-block can include the inner sleeve being sleeved on outside vent stack 2 and to be wrapped in this interior
Peplos outside set, thus by being provided with bite-block at the outer sheath of vent stack 2, to guide patient that bite-block is engaged, make
Patient cannot directly bite vent stack 2, and then plays the effect protecting vent stack 2, extends its service life, rises simultaneously
To avoiding patient to sting the bad or vent stack 2 that breaks by the teeth, cause gas leakage, dangerous effect occurs.Further, above-mentioned bite-block both can be
Full fixed cover is located at outside vent stack 2 and arranges, and can be again the setting outside vent stack 2 that is slidably located in.
Additionally, in the laryngeal mask of this utility model embodiment offer, the outer surface of vent stack 2 is also provided with graduation mark
(not shown).This graduation mark can be used in weighing and indicates the concrete degree of depth position that laryngeal mask has inserted in patient's pharyngeal cavity venturi
Put, thus be beneficial to being smoothed out of operation.
The topmost advantage that the laryngeal mask that this utility model embodiment provides has is:
Owing to, in the laryngeal mask that this utility model embodiment provides, above-mentioned vent stack 2 is swan-neck, it is possible to make vent stack
2 are vertical setting with cuff 3 entirety, i.e. ensure that laryngeal mask is consistent with the anatomical angulation of human body bottleneck throat, and therefore this practicality is new
During the laryngeal mask that type embodiment provides inserts human body pharyngeal cavity, overall running resistance is less, it is possible to be prevented effectively from Oropharynx mucosa
Damage.
Additionally, the laryngeal mask that this utility model embodiment provides also has following 5 advantages:
One, drainage tube 4 is arranged with the two-chamber of vent stack 2, it is possible to attracts gastric juice, it is to avoid reflux erroneous aspiration, causes air flue not
Suitable.
