The specific embodiment
As shown in Figure 1:
Intermediate conductor 1 both sides are provided with a left side conduit 6, right side conduit 7 respectively, and intermediate conductor 1 leading portion is longer than left side conduit 6, right side conduit 7, and the 6-10 centimetre is got 8 centimeters in this example; Left side conduit 6, right side conduit 7 front ends are cecum, little cover capsule 2 is set on intermediate conductor 1 leading portion, on intermediate conductor 1, left side conduit 6, right side conduit 7 back segment arranged side by side, big cover capsule 4 is set, big cover capsule 4 is connected on the outer surface of intermediate conductor 1, left side conduit 6, right side conduit 7, big cover capsule 4 is got 14 centimeters apart from intermediate conductor 1 front end (being the top) 12-16 centimetre in this example; Be provided with passage 3 at distance left side conduit 6, right side conduit 7 front end 6cm with interior front, 5 oval-shaped passages 3 are respectively arranged in this example, it is of a size of long 0.5cm, and wide 0.25cm arranges before and after being; Joint 5 on left side conduit 6, right side conduit 7 ends is used for connecting the various mechanical interfaces of anesthetic machine.
In the concrete application process, according to patient's needs, selecting dissimilar this utility model is double-cavity trachea catheter.Tube chamber of conduit 1 front end 6-10cm can insert in the esophagus at an easy rate in the middle of it, the left side conduit 6 of both sides, the blunt slick projection of right side conduit 7 nose circles can be ridden very naturally and be stayed in outside the esophagus opening, make left side conduit 6, right side conduit 7 integral body to be deep in the esophagus again; This moment, promptly expression left side conduit 6, right side conduit 7 were in place; After overlapping little cover capsule 2 inflation of capsule 4 and intermediate conductor 1 front end greatly, just can fix left side conduit 6, right side conduit 7 and the position of intermediate conductor 1 in the oral cavity, and the turnover of each conduit of shutoff void gas outward and between the esophagus, mouth, nasal cavity fully; This moment is because 5 pairs of elliptical vent hole 3 that conduit 6, right side conduit 7 front front ends respectively have on the left of the both sides just in time are in patient's throat section, so when left side, both sides conduit 6, right side conduit 7 rear ends and anesthetic machine join capable mechanical ventilation, can guarantee the effective ventilation effect of left side conduit 6, right side conduit 7.
