Abstract
A laryngeal mask comprises a mask bag and a gas-filled pipe. The gas-filled pipe comprises a pipe body, the tail end of the pipe body is connected with the inner cavity of the mask bag, the gas-filled end of the gas-filled pipe is provided with a connection head, the gas-filled end is provided with an indicating gas bag between the connection head and the pipe body, and a deflation valve is arranged between the connection head and the indicating gas bag. According to the fact that the gas-filled end of the gas-filled pipe is provided with the deflation valve and the indicating gas bag, gas in the mask bag can be exhausted rapidly after operation, surplus gas quantity inside the mask bag can be judged through the indicating gas bag during a gas exhausting process, and intuition effect is achieved.
Description
Technical field
This utility model relates to a kind ofly to be inputted medium in the human body or is passed to apparatus on the human body, relates to specifically a kind of trachea intubate.
Background technology
Laryngeal mask is that Brain also at first advocates a kind of device that adopts the ventilation of glottis external square type that uses in the nineteen eighty-three invention, in order to improve the clinical application effect of laryngeal mask, the laryngeal mask of at present existing three types: the first is Standard laryngeal mask airway, it also is at present clinical laryngeal mask the most commonly used, the gas tube that basic structure has cover capsule, airway and inflates for covering capsule, be mainly used in keeping the respiratory tract function, can not carry out drainage procedure; The second is the Special laryngeal mask of guidance tracheal intubation; The third is the conduction type laryngeal mask, except being used for keeping the respiratory tract function, also be used for the esophageal regurgitation material is carried out drain, similar is in common laryngeal mask, just increased a drainage tube parallel with breather, when above-mentioned various laryngeal mask took out after operation, the gas in the cover capsule usually was used by syringe, check (non-return) valve gas is extracted out, and deflation course is slower.
The utility model content
The purpose of this utility model provides a kind of laryngeal mask, and its deflation course is very fast.
To achieve these goals, technical solution of the present utility model is: a kind of laryngeal mask, comprise cover capsule, gas tube, gas tube comprises body, the end of body is connected in cover capsule inner chamber, the inflation end of gas tube is provided with union joint, and described inflation end is provided with pilot balloon between union joint and body, be provided with vent valve between described union joint and the pilot balloon.
After adopting such scheme, therefore this utility model laryngeal mask can emit the gas in the cover capsule after the operation fast because the inflation end of gas tube is provided with vent valve and pilot balloon, and in the deflation course, judge the volume of rest gas of covering in the capsule by pilot balloon, more directly perceived.
Description of drawings
Fig. 1 is the structural representation of this utility model laryngeal mask;
Specify this utility model laryngeal mask below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, this utility model laryngeal mask comprises cover capsule 1, gas tube 3, gas tube 3 comprises body 34, the end of body 34 is connected in cover capsule 1 inner chamber, the inflation end of gas tube 3 is provided with union joint 31, the inflation end is provided with pilot balloon 32 between union joint 31 and body 34, be provided with vent valve 33 between described union joint 31 and the pilot balloon 32.
Before the operation, the cover capsule 1 of laryngeal mask being inserted patient's throat, the union joint 31 of gas tube 3 is connected with source of the gas, is 1 inflation of cover capsule, after operation is finished, opens vent valve 33, and the gases in cover capsule 1 and the pilot balloon 32 are emitted, and will cover capsule 1 again and take out from patient throat.
The above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from this utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
