The utility model content
The technical problems to be solved in the utility model is: a kind of difficult throat cover air flue conduit pipe device that affects the visual field of surgical doctor is provided.
In order to solve the problems of the technologies described above, this utility model comprises airway, cover capsule and to the aerating and exhaust device of blister cavities inflation/deflation of cover capsule, described airway is an elasticity body that has at least one bending when free state, has at least the operating position of a bending to be in oral external.
For the ease of making, described airway is an elasticity body that has a bending when free state.
Described airway is an elasticity body that has two bendings when free state, and the operating position that the operating position of a bending is positioned at oral external, another bending is positioned at inside, oral cavity.On airway, the operating position is positioned at intraoral bending with respect to straight tube more fit human oral cavity and pharyngeal physiological bending, makes and inserts Simple fast more, need not any supplementary means; When inserting patient's mouth, can reduce oral cavity and pharyngeal mucosa injury, reduced the untoward reaction of the pharyngeal pain discomfort of postoperative patient.
In order to make every kind of throat cover air flue conduit pipe device can adapt to a kind of operation, described operating position is positioned at the bending of inside, oral cavity to the rear bending of cover capsule, and described operating position is arranged in the bending of oral external to any one direction bending of upper and lower, left and right four direction of cover capsule.
In order to improve the comfortableness of use, the angle of bend of the bending on described airway is 90 °～100 °.
Described airway subscript is marked with the length scale, and 0 scale value of length scale is corresponding bottom with the cover capsule.The length scale makes the insertion depth of throat cover air flue conduit pipe device controlled, and optimum depth is that airway is positioned at the outer end of extrabuccal bending apart from the 1.5-2cm of face.
In order to improve the intensity of airway, described airway comprises plastic outer tube and the tinsel spiral winding pipe of lining in plastic outer tube.
For the ease of the inflation/deflation of air bag, described aerating and exhaust device comprises gas tube and the indication capsule that is arranged on gas tube, and gas tube is communicated with the blister cavities of cover capsule.
The beneficial effects of the utility model are: this utility model is in extrabuccal bending by be provided with the operating position on airway, making airway stretch out the part in oral cavity can be crooked along face, take up room little, can selectively avoid surgery location, do not affect the visual field of surgical doctor, provide smoothly more favourable guarantee for operation.And be convenient to spread operation dressing, airway can not be out of shape because of the operation dressing extruding, and airway can not stop up, and can not cause patient respiratory to be obstructed, and safety is good.

The specific embodiment
Specific embodiment one
A kind of specific embodiment one as shown in Figure 1, it comprises airway 2, cover capsule 4 and to the aerating and exhaust device of blister cavities inflation/deflation of cover capsule 4, one end of airway 2 is connected with cover capsule 4 by connector 3, make airway 2 be communicated with the centre bore of cover capsule 4, aerating and exhaust device comprises gas tube 5 and indication capsule 6, indication capsule 6 is arranged on gas tube 5, gas tube 5 is communicated with the blister cavities of cover capsule 4, cover capsule 4 and aerating and exhaust device and cover capsule 4 are prior art with the syndeton of airway 2, can adopt the various versions of prior art.
The improvement with respect to prior art of this specific embodiment is: airway 2 is elasticity bodys that have a bending 2-1 when free state, and the operating position of this bending 2-1 is in oral external.This bending 2-1 is crooked to the rear of cover capsule 4.In this patent, the orientation of indication is take the cover capsule as reference, after cover capsule 4 is placed in pharynx something lost cavum laryngis, the back of human body is defined in the place ahead of cover capsule 4, the face of human body is defined in the rear of cover capsule 4, the eye of human body is defined in the top of cover capsule 4, the lower jaw of human body is defined in the below of cover capsule 4, and other two orientation are left and right directions.The angle of bend of bending 2-1 is preferably 90 °～100 °.Be preferably in mark length scale on airway 2,0 scale value of length scale is corresponding bottom with cover capsule 4, and the length scale is preferably in the 1 place end of machine end joint.Airway 2 can adopt plastic tube or plastic outer tube and the lining tinsel spiral winding pipe in plastic outer tube.
