The laryngeal mask allowing the endoscope to be inserted can be simultaneously used with the endoscope together. The laryngeal mask allowing the endoscope to be inserted comprises a main tube (1), a mask bag (2) is connected with one end of the main tube (1), and a main tube endoscope channel cavity is formed in the main tube (1), and a mask bag endoscope channel cavity (21) is formed in the mask bag (2). One end of the mask bag endoscope channel cavity (21) is located at the tail end of the mask bag (2). The other end of the mask bag endoscope channel cavity (21) is communicated with the main tube endoscope channel cavity (11).
Description
Technical field
This utility model relates to a kind of trachea intubate, particularly relates to a kind of laryngeal mask.
Background technology
Laryngeal mask is Brain in the nineteen eighty-three invention and at first advocates use a kind of and adopt the device that mode is ventilated outside the glottis.In order to improve the clinical application effect of laryngeal mask, have three types laryngeal mask at present: first kind is the standard type intubating laryngeal mask airway, it also is at present clinical intubating laryngeal mask airway the most commonly used, its basic structure has the cover capsule, be responsible for and be the gas tube of cover capsule inflation, generally be provided with venting cavity in the person in charge, the cover capsule is provided with passage, venting cavity is communicated with passage, gas tube is communicated with the cover capsule, drain the air that covers in the capsule by gas tube earlier in use, the cover capsule becomes flat, thereby treat that laryngeal mask is inserted throat heaves the cover capsule by gas tube to covering the air that injects ormal weight in the capsule afterwards more again, the cover capsule after heaving can be fitted preferably with the throat tissue of human body and be formed sealing, and then venting cavity is communicated with person's windpipe, this laryngeal mask is mainly used in keeping the respiratory tract function, can not carry out drainage procedure; Second kind is the laryngeal mask that has drainage tube, because people's trachea and esophagus converge in throat, generally be positioned at the porch of esophagus at the end of inserting throat's back cover capsule, the laryngeal mask that has drainage tube generally arranges conduction hole at the end of cover capsule, other is provided with drainage tube and is communicated to conduction hole, drainage tube can be communicated with the human body esophagus after inserting laryngeal mask like this, thereby can carry out drainage procedure when setting up airway; The third is the special-purpose intubating laryngeal mask airway of guidance tracheal intubation.About the structure of conduction type laryngeal mask, can be 201210299776.9 at the application number that proposes before referring to the applicant, application publication number is CN102784431A, Shen Qing Publication day to be the disclosed a kind of conduction type laryngeal mask of Chinese invention patent application on November 21st, 2012.At present, when using laryngeal mask to carry out anesthesia surgery, some patient need insert endoscope and enter in the patient body to observe or assisted surgery when operation, at this moment special passage just need be arranged with insertion endoscope.Present common laryngeal mask is mainly used in airway pressure, special passage is not set, therefore some needs the patient of endoscopic surgery just can not select to use laryngeal mask to undergo surgery, and need ventilate or cutting opening inserts endoscope by tracheal intubation, increased patient's misery like this, damaged also bigger.
The utility model content
The technical problems to be solved in the utility model provides a kind of laryngeal mask of the inserted endoscope that can be simultaneously uses with endoscope.
This utility model can be inserted the laryngeal mask of endoscope, comprise the person in charge, an end of being responsible for is connected with the cover capsule, be provided with in the wherein said person in charge and be responsible for the endoscope path way chamber, be provided with cover capsule endoscope path way chamber in the described cover capsule, one end in described cover capsule endoscope path way chamber is positioned at the end of described cover capsule, and the other end in described cover capsule endoscope path way chamber is communicated with described person in charge's endoscope path way chamber.
The laryngeal mask difference from prior art that this utility model can be inserted endoscope be laryngeal mask that this utility model can insert endoscope be responsible for and the cover capsule in be respectively equipped with and be responsible for endoscope path way chamber and cover capsule endoscope path way chamber, person in charge endoscope path way chamber and cover capsule endoscope path way chamber are interconnected to constitute and can supply the passage of endoscope's insertion, when using this utility model can insert the laryngeal mask of endoscope, can in this passage, insert endoscope when needed like this, to reach the purpose of using endoscope when using laryngeal mask simultaneously.
The laryngeal mask that can insert endoscope to this utility model below in conjunction with accompanying drawing is described further.
Description of drawings
Fig. 1 can insert the rearview of first embodiment of laryngeal mask of endoscope for this utility model;
Fig. 2 can insert the axonometric chart of cover capsule among first embodiment of laryngeal mask of endoscope for this utility model.
The specific embodiment
As shown in Figure 1, first embodiment of laryngeal mask that this utility model can be inserted endoscope comprises the person in charge 1, an end of the person in charge 1 is connected with cover capsule 2, be responsible in 1 and be provided with venting cavity 12, venting cavity 12 is communicated with (passage is not shown in the drawings) with the passage of cover on the capsule 1, unlike the prior art be: be responsible for to be provided with in 1 and be responsible for endoscope path way chamber 11, be provided with cover capsule endoscope path way chamber 21 in the cover capsule 2, referring to Fig. 2, one end in cover capsule endoscope path way chamber 21 is positioned at the end of cover capsule 2, and the other end in cover capsule endoscope path way chamber 21 is communicated with person in charge's endoscope path way chamber 11.
Present embodiment uses according to the mode of common laryngeal mask in use, different is when needs insert endoscope, endoscope to be passed from be responsible for endoscope path way chamber 11 and cover capsule endoscope path way chamber 21 successively, end through cover capsule 2 passes, and reaches the function that can use endoscope simultaneously.
Above-described 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 those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of this utility model claims.
Claims (1)
1. the laryngeal mask that can insert endoscope, comprise the person in charge (1), an end of being responsible for (1) is connected with cover capsule (2), it is characterized in that: be provided with in the described person in charge (1) and be responsible for endoscope path way chamber (11), be provided with cover capsule endoscope path way chamber (21) in the described cover capsule (2), one end in described cover capsule endoscope path way chamber (21) is positioned at the end of described cover capsule (2), and the other end in described cover capsule endoscope path way chamber (21) is communicated with described person in charge's endoscope path way chamber (11).
