Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

With reference to Fig. 1, the trachea cannula of the anti-respiratory tract injury of the present embodiment includes: tube body 100, suction tube 200, gas tube 300 and air bag 400, the tube wall of 100 first end of tube body is equipped with the hole Mo Fei 103, and second end is equipped with connector 102.Air bag 400 is arranged Close to the one end in the hole Mo Fei 103 on tube body 100, gas tube 300 penetrates in tube body 100 from the tube wall of the other end of tube body 100, And it is connected to air bag 400.Suction hole 101 is additionally provided on the tube wall of tube body 100, suction hole 101 and Mo Feikong 103 are located at gas The both ends of capsule 400.Suction tube 101 penetrates in tube body 100 from the tube wall of the second end of tube body 100, and with suction hole 101 and Mo Fei Hole 103 is connected to.As shown in figure 4, the trachea cannula of the present embodiment further includes the silica gel sleeve pipe for being set in 100 first end of tube body 500, silica gel sleeve pipe 500 stretches out of length no more than 3mm of 100 first end of tube body, and the hole Mo Fei 103 is through silica gel sleeve pipe 500 Tube wall.

The trachea cannula of the anti-respiratory tract injury of the present embodiment is arranged with silica gel sleeve pipe 500 in one end of insertion respiratory tract, And of length no more than 3mm of 500 projecting end of silica gel sleeve pipe, therefore, when being inserted into trachea cannula, harder end will not be direct It is in contact with respiratory mucosa, silica gel material is softer, will not damage respiratory mucosa, and the length of silica gel sleeve pipe projecting end Degree is no more than 3mm, will not occur to bend or deform to cause open-ended to become smaller or block.

In the present embodiment, air bag 400 includes that intermediate filling part 401 and both ends are pasted onto paste section 402 on tube wall, silica gel The wall section that casing 500 entangles is intersected with the region that the paste section 402 close to 103 one end of the hole Mo Fei covers tube wall, and close The paste section 402 of 103 one end Mo Feikong is covered on 500 outside of silica gel sleeve pipe.Since silica gel sleeve pipe 500 is set in tube body 100 The end of one end is pasted onto the outside of silica gel sleeve pipe 500 using the paste section 402 of air bag 400, avoids silica gel to avoid falling off Casing 500 slides.

Further, a part close to the paste section 402 of 103 one end of the hole Mo Fei is pasted onto 500 outside of silica gel sleeve pipe, separately A part is pasted onto the outer wall of tube body 100.Silica gel sleeve pipe 500 is set in the outer wall of tube body 100, although silica gel has certain elasticity, It can be close to tube wall, but be placed in the case where there are still gas leakage in human respiratory tract for a long time, a part of paste section 402 is straight Connecing the part pasted with the tube wall of tube body 100 ensure that the air-tightness of air bag 400.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
