Abstract
The utility model belongs to a medical equipment, which is characterized in that an inner cavity or a catheter wall of a tracheal catheter is provided with a function tubule of which the end is led out from the inner cavity of a catheter body near the side end of the catheter body; the end is connected with a joint; the front end of the function tubule is arranged in a beveled edge end of a tracheal catheter body. Compared with the common single cavity tracheal catheter, the utility model is added with one function tubule, and therefore, except for the function of the general air tube, the utility model also has the advantages that superficial anesthesia of pars laryngea pharyngis, the administration of the air tube, sputum suction in the air tube, and the high-frequency ventilation can be conveniently carried out, the low flow oxygen is persistently supplied to the patient keeping the tracheal catheter after the operation, etc.
Description
This utility model belongs to a kind of medical apparatus and instruments, particularly a kind of endotracheal tube.
Existing endotracheal tube just is made of the inflatable cuff of breather and leakproof simply, and such structure has several shortcomings: need to insert sputum aspirator tube in addition when 1, inhaling expectorant midway and suspend ventilation to suck with anesthetics, easily cause the fluctuation of anoxia and depth of anesthesia; When 2, needing in the trachea administration, also need suspend ventilation; 3, be not easy to carry out high frequency ventilation or continuous administration of low flow oxygen.4, can not be used for going to insert leading and inhale expectorant and bottleneck throat table fiber crops.
The purpose of this utility model is to provide a kind of endotracheal tube with multiple function, can solve following point:
(1) is convenient to administration in the trachea, when setting up, can gives medicines such as epinephrine easily through this pipe as not reaching at emergency resuscitation initial stage venous channel.
(2) can carry out at any time that endotracheal suction (ets) but need not to interrupt to ventilate or the suction of anesthetic gases.
(3) be convenient to implement high frequency ventilation or continuous administration of low flow oxygen.
(4) feasible suction expectorant and bottleneck throat sprayed the table anaesthetic before endotracheal tube inserted.
This utility model is achieved in that it by the endotracheal tube body, connection tube, inflatable cuff, formations such as inflation tubule.Have an elliptical aperture near the endotracheal tube body angle end, connection tube links to each other with the proximal end of endotracheal tube body, one end of inflation tubule is equipped with gas-charging connection, the inflation tubule links to each other with inflatable cuff by the filling channel of opening at the endotracheal tube body sidewall, in the inner chamber of endotracheal tube body or tube wall, be provided with a function tubule, the end of function tubule is at close catheter body proximal end place, from the inner chamber of catheter body, draw, end is connected with joint, and the front end of function tubule is arranged on the angle end of endotracheal tube body.The front end of function tubule is drawn from the angle end of endotracheal tube body, has side opening on the tube wall of front end, and the part of function tubule intracavity in the endotracheal tube of nearly angle end also has a side opening.The function tubule also can be arranged in the tube wall with the catheter body of filling channel offside, has side opening on the front end of function tubule.
The general single-lumen bronchial tube of this utility model has increased a function tubule, so except that possessing general endotracheal tube function, can go administration in the bottleneck throat table fiber crops, trachea in addition easily, endotracheal suction (ets), high frequency ventilation, to advantages such as postoperative patient with endotracheal tube continuous administration of low flow oxygen.
Below in conjunction with drawings and Examples this utility model is further described.
Fig. 1 is the structural representation of embodiment 1 of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the structural representation of embodiment 2 of the present utility model.
Fig. 4 is the A-A profile of Fig. 3.
Endotracheal tube body 1, connection tube 2, inflatable cuff 3, inflation tubule 4, filling channel 5, function tubule 6, joint 7, side opening 8, side opening 9, gas-charging connection 10, the inner chamber 11 of endotracheal tube body, the elliptical aperture 12 of endotracheal tube body.
Embodiment 1: in the present embodiment, function tubule 6 as one independently pipe draw from trachea conductor 1 and angle end, have side opening 8 on the tube wall of the front end of function tubule 6, its part in inner chamber 11 also has side opening 9.Side opening 8 mainly is to be used to inhale expectorant.Side opening 9 can be the expectorant sucking-off in the endotracheal tube inner chamber 11.The end of function tubule 6 is drawn from the proximal end of endotracheal tube body.Joint 7 is a ledge structure, so that connect the equipment of different bores, as connection tube of syringe, oxygen catheter and suction pump etc.During the function of use tubule, available cap seal is not lived joint 7.
Embodiment 2: in the present embodiment, function tubule 6 is arranged in the tube wall with the catheter body 1 of filling channel 5 offsides, have side opening 8 on the front end of function tubule, side opening 8 not only can be inhaled expectorant, also can extenuate oxygen supply air pressure, joint 7 is a ledge structure, so that connect the equipment of different bores, during without function tubule 6, can seal joint 7.
The structure of present embodiment can keep the net sectional area of endotracheal tube body tube chamber.
