By directly arranging the adhesive button on the artificial nose, the electrode sheet can be directly attached to achieve fixation. The electrode sheet can be attached to the patient's body, limbs or operating bed. When the position and direction of the breathing circuit need to be adjusted, the adhesive button is only needed to be detached from the original electrode sheet. After adjustment, the electrode sheet is attached to the desired position, and the adhesive button is attached to the new electrode sheet.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) By rotatably connecting the first port and the connecting pipe at both ends of the elbow tube, the breathing circuit can be directly rotated through the annular groove and the annular buckle to adjust the angle of the threaded tube. The threaded tube can be directly rotated to prevent accidental twisting or folding. This allows medical staff to flexibly adjust the position of the endotracheal tube according to the surgical needs and ensures that the endotracheal tube will not be rotated or deformed. This makes it easier to expose the surgical area and allows surgeons to perform related operations with greater confidence, reducing complications caused by improper operation.

[0021] (2) By attaching adhesive buttons to the artificial nose and engaging with electrode pads, the breathing circuit can be stably and securely fixed to the patient's body, limbs, or operating table.

When the position or direction of the breathing circuit needs to be adjusted during surgery, medical personnel simply need to gently disconnect the adhesive buttons from the original electrode pads, then attach the new electrode pads to the desired position and reattach the adhesive buttons. The entire process requires no complicated disassembly and reinstallation steps, providing medical personnel with a safer, more convenient, and more efficient fixation method.

[0022] (3) By setting a piston port at the bend of the elbow tube, the opening is tightly blocked with the piston cap during ventilation to prevent gas leakage and ensure the safety of ventilation. When suctioning is required, medical staff can simply pull out the piston cap and insert the suction tube through the piston port to perform the suctioning operation, which simplifies the suctioning process and improves work efficiency.

[0023] (4) By designing the connecting tube as a pleated flexible tube, it has the functions of extension and bending, and can be adjusted according to the specific needs of clinical surgery. Whether it is necessary to lengthen it to adapt to long-distance surgical operations, to shorten it to ensure the compactness of the breathing circuit, or to bend it to adapt to specific surgical positions or space constraints, this design can easily cope with them.
