Embodiment 1

[0032] Such as Figure 1-Figure 4 As shown, the present invention discloses a tracheal intubation tube, comprising a tube body 1, the side wall of the middle part of the tube body 1 has an air hole 2; when the tube body 1 is inserted into the trachea, one end of the tube body 1 is inserted into the In the case of one bronchus, the stomata 2 is just in communication with the other bronchus; the inner wall of the tube body 1 and the stomata 2 are provided with a stomata baffle 3 that matches the stomata 2, and the stomata baffle 3 can be positioned along the tube body 1 slide. The air holes 2 are waist-shaped openings.

[0033] The air hole blocking piece 3 is connected with a driving mechanism, and the driving mechanism can drive the air hole blocking piece 3 to slide, and then open or close the air hole 2; the tube body 1 is provided with several outer bags and inner bags, and the outer bag and the inner bag The cuff is connected to the injection port on the outside by a thi...

Abstract

The invention discloses a trachea cannula. An air hole is formed in the side wall of the middle of a trachea cannula body. When the trachea cannula is inserted into a trachea and one end of the trachea cannula is inserted into one bronchia, the air hole is just communicated with the other bronchia oppositely. An airhole baffle matching the air hole is formed in the position, corresponding to the air hole, of the inner wall of the trachea cannula body and can slide along the trachea cannula body. Therefore, the wounds formed by using the trachea cannula can be reduced and the body injury of a patient can be reduced. When intubation is performed, the intubation difficulty can be reduced and free ventilation of the two lung lobes and switching of ventilation channels are realized; the outer diameter of the trachea cannula is reduced when the inner diameter of the cannula is large enough and thus the injuries to a patient are reduced; and the inner diameter can be increased under the condition that the outer diameter is fixed, so that the circulation diameter of gas is increased and better gas circulation performance is realized.

Description

technical field [0001] The invention relates to the field of tracheal intubation, in particular to a tracheal intubation which can be used for one-lung ventilation. Background technique [0002] There are many tracheal intubations at present, and their function is to ensure the breathing of the patient. The endotracheal intubation is inserted into the cut trachea, and the other end is connected with the artificial respirator to realize artificial respiration. Ordinary tracheal intubation can only be inserted and removed once to achieve unilateral air supply. Because the intubation process is invisible, it is difficult to insert it to one side of the surgical site at one time, and it often takes a long time. Because it was inserted into the side of the non-surgical position by mistake, it was necessary to take out a section and insert it into the side of the surgical position. Such tossing will increase the pain of patients needlessly, which makes people afraid even thinking...
