Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in fig. 1, a printed electrode type recurrent laryngeal nerve intubation with a cleaning function comprises a one-way valve 1, an indicating balloon 2, a connector A3, a connector B4, a connector C5, an electrode plug 6, a tube body 8, a printed electrode 10, a cuff 11, a developing layer 12, a suction tube 13 and a perfusion or gas balance tube 14; the one-way valve 1 is connected with an indicating balloon 2, the indicating balloon 2 is connected with the inside of a cuff 11 through an inflation tube, an electrode plug 6 is connected with a printing electrode 10 through an electrode lead 7, a joint B4 is connected with a perfusion or gas balance tube 14, a joint C5 is connected with a suction tube 13, and an insulating layer 9 is arranged on the part, which does not need to be exposed, of the surface of the printing electrode 10.

The developer layer 12 is a developer coating or tube, which is located at the electrode.

The number of the printed electrodes 10 is two or more.

The insulating layer 9 is an insulating coating or an insulating heat shrink tube or an insulating sleeve.

The tube body 8 is internally provided with an inflation tube channel 16, a suction channel 17, a perfusion or gas balance channel 18 and a breathing machine oxygen supply channel 19.

The inside of the tube body is also provided with a spiral stainless steel wire 20, and the spiral stainless steel wire 20 is tightly attached to the inner wall of the tube body and plays a supporting role.

The joint of the machine end is connected with a breathing machine, and the breathing machine can deliver oxygen through a breathing machine oxygen delivery channel in the tube body during operation.

The needle cylinder or the instrument is used, the cuff at the end of the patient is inflated through the inflation tube, and the machine end of the inflation tube is provided with the one-way valve, so that the pressure loss of the cuff in the operation is avoided.

In the operation process, the printing electrode is used for detecting the recurrent laryngeal nerve electrical signal, the electrode is 15-70 mm away from the cuff, and the length of the electrode of the effective use part is as follows: 5-40 mm, the electrode is printed on the surface of the tube body according to the mode shown in the figure, and an insulating coating is needed at the machine end of the tube body, so that the effective use part length of the electrode is ensured.
