[specific embodiment]
Below in conjunction with accompanying drawing and specific embodiment, describe the present invention in detail, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1 and Figure 2, visual flexible double lumen endobronchial tube described in this specific embodiment, it comprises double lumen endobronchial tube body, described double lumen endobronchial tube body comprises a main trachea tube chamber 1 and a bronchus tube chamber 2, and a spiral steel wire ring set 8 is set in the tube wall of this double lumen endobronchial tube body; In described bronchus tube chamber 2, plug a soft inner tube 3, the inner termination of this soft inner tube 3 is a cecum 33; By this soft inner tube 3 can insert visible system in peep bar 9; The external end head of peeping bar 9 in described stretches out outside bronchus tube chamber 2, is connected with the display device 10 of visible system, and this interior inner termination of peeping bar 9 can be inserted to cecum 33 places at soft inner tube 3 inner termination places; Described main trachea tube chamber 1 end and bronchus tube chamber 2 ends respectively arrange main trachea tube chamber air bag 4 and a bronchus tube chamber air bag 5, and main trachea tube chamber airbag inflation pipe 7 and the bronchus tube chamber airbag inflation pipe 6 corresponding with main trachea tube chamber air bag 4 and bronchus tube chamber air bag 5; Described main trachea tube chamber airbag inflation pipe 7 is communicated with main trachea tube chamber air bag 4, can be by main trachea tube chamber airbag inflation pipe 7 to main trachea tube chamber air bag 4 inflations; Described bronchus tube chamber airbag inflation pipe 6 is communicated with bronchus tube chamber air bag 5, can be by bronchus tube chamber airbag inflation pipe 6 to 5 inflations of bronchus tube chamber air bag.
The external end head of described soft inner tube 3 arranges an invayination plush copper 32, and this invayination plush copper 32 arranges a soft interior pipe through-hole 31 communicating with soft inner tube 3 bodys; This invayination plush copper 32 be located in the collar extension of bronchus tube chamber 2, avoids soft inner tube 3 to fall in human body bronchus through bronchus tube chamber 2.
When the present invention uses, double lumen endobronchial tube body has two tube chambers, bronchus tube chamber 2 and main trachea tube chamber 1; The tube wall built-in screw type steel wire ring set of double lumen endobronchial tube body, makes the soft resistance to compression of conduit, can free bend, there is good stickiness, and than existing hard double lumen endobronchial tube, damage little many; The soft inner tube 3 that the built-in end of bronchus tube chamber 2 is cecum, cecum is positioned at the end openings place of bronchus tube chamber.Soft inner tube 3 in order to place visible system in peep bar 9, inside peep bar 9 and there is certain toughness, can guide cannula, when peeping under bar 9 guiding after intubate completes interior, fill and open main trachea chamber air bag 4 and bronchus tube chamber air bag 5, A/C, peeps bar 9 and soft inner tube 3 in extracting, connecting respirator can ventilate.The soft inner tube 3 that design end is cecum, can isolate clear area and contaminated area on the one hand, reduces the risk of patient's cross infection; Can reduce the cleaning-sterilizing frequency of visible system on the one hand, reduce the loss of visible system.
In in the present invention, peep bar 9 and its display being connected 10 composition visible systems, this system has light source, there is the knob that can regulate visible system end bending direction and angle of bend, in inciting somebody to action before intubate, peeping bar 9 inserts in the intraluminal soft inner tube 3 of bronchus to its cecum 33, open light source, regulate direction and angulation knob, guiding is inserted in bronchus tube chamber to laterobronchus.
The built-in spiral wire of double lumen endobronchial tube tube wall of this double lumen endobronchial tube body, conduit soft pliable is bent, in use, peeping bar 9 can directly guide bronchus tube chamber to insert a laterobronchus that needs insertion, no matter be left side or right side, so double lumen endobronchial tube no longer includes dividing of the right pipe of left pipe.
Distance between its main trachea tube chamber air bag 4 and bronchus tube chamber air bag 5 is enough far away, prevents to main trachea tube chamber air bag 4 after airbag aeration, blocking opposite side bronchus opening through bronchus tube chamber airbag inflation pipe 6 and main trachea tube chamber airbag inflation pipe 7.
Visual flexible double lumen endobronchial tube of the present invention, its adopts a spiral steel wire ring is set in double lumen endobronchial tube tube wall, at bronchial tube intracavity, one soft inner tube is set, by this soft inner tube can plug visible system in peep bar, this interior display device of peeping bar external port connection visible system, it has simple in structure, and soft resistance to compression can free bend, there is good stickiness, tissue injury is little, uses that visualized operation is convenient to be checked, the advantage such as increase work efficiency.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
