Embodiment Construction

[0010] The device of the present invention is composed of a double-lumen cannula 1 and a long bifurcated tube 2, the long bifurcated tube 2 is connected to one side lumen of the double-cavity cannula 1, and the other side lumen of the double-cavity cannula 1 is connected to the right bifurcated tube 4. The shape is an inverted Y shape. The double-chamber intubation tube 1 is connected with an auxiliary flashboard 5. The auxiliary flashboard 5 is inverted Y-shaped, and its cross section is an arc-shaped flat tube. The auxiliary flashboard 5 is equipped with a clutch control lever 7 and a separation The fork control rod 8, the auxiliary insert 5 and the double-chamber cannula 1 are pasted together, and the main rod of the double-chamber intubation 1 and the auxiliary insert 5 is clamped together by a fixed clip 6, and the long fork tube 2 and the right fork The pipe 4 is also clamped together with the branch pipes 11 of the corresponding auxiliary flashboard 5 through other fixin...

Abstract

The invention relates to an accurate-positioning double-chamber trachea cannula for anesthesia, and belongs to the technical field of medical instrument manufacturing. A double-chamber cannula body is connected with an auxiliary insertion plate, the cross section of the auxiliary insertion plate is an arc-shaped flat tube, a separation and reunion control lever and a bifurcation control lever are mounted in the auxiliary insertion plate which is stuck to the double-chamber cannula body together, fixation clamps clamp the double-chamber cannula body and a main lever of the auxiliary insertion plate into a hole, a pressure switch is mounted at the juncture of the auxiliary insertion plate and branch tubes, and the pressure switch is connected with a display. The distance from the oral cavity to the bronchi is judged by the aid of an x-ray film of a patient before surgery, the double-chamber cannula body and the auxiliary insertion plate are inserted into the trachea from the oral cavity together to enable two bifurcated tubes of the double-chamber cannula body to enter the left and right bronchi, when the pressure switch reaches the carina of the trachea, a lamp of the display is lighted, and the auxiliary insertion plate is taken out from the trachea. The double-chamber cannula body is placed in the trachea accurately and controllably.

Description

technical field [0001] The invention belongs to the technical field of medical equipment manufacturing, and relates to a double-lumen tracheal intubation tube for operation anesthesia. Background technique [0002] Before the operation, the patient generally needs to be anesthetized. In order to ensure that the patient can breathe under anesthesia, a tube is inserted into the trachea through the mouth, and breathing is performed with the help of a ventilator. The purpose of double-lumen tracheal intubation is to completely isolate the ventilation of the left and right lungs, and to perform independent ventilation of the left and right lungs, so as to ensure the safety of the patient and establish appropriate conditions for the success of the operation. The currently used double-lumen endotracheal tube is made of plastic or rubber, and a long bifurcated branch (left branch or right branch) extends downward from the lower end of the double-lumen tube trunk unilaterally, and en...
