Multifunctional double-lumen tube intubation tube beneficial to airway management in perioperative period

Abstract

The invention discloses a multifunctional double-lumen tube intubation tube beneficial to airway management in a perioperative period. The multifunctional double-lumen tube intubation tube comprises a long breathing tube and a short breathing tube arranged at one side of the long breathing tube in a sliding manner, one end of the long breathing tube and one end of the short breathing tube are respectively communicated with a breathing machine, the other end of the long breathing tube and the other end of the short breathing tube are set to be communicated with a respiratory tract, at least one of the long breathing tube and the short breathing tube is of a double-wall structure, the double-wall structure comprises an inner wall and an outer wall, a drainage cavity channel is arranged between the inner wall and the outer wall, multiple attraction holes communicated with the drainage cavity channel are formed in one end, contacted with the respiratory tract, of the inner wall, an attraction hole which can suck out secretions inside the drainage cavity channel is arranged at one end, close to the breathing machine, of the outer wall, and a cover body is arranged on the attraction hole. When the multifunctional double-lumen tube intubation tube is used for attracting the secretions in the respiratory tract, the long breathing tube and the short breathing tube do not need to be disconnected from the breathing machine, and the condition that the respiratory tract is damaged due to negative pressure caused by invalid attraction and multiple invalid attraction attempts as the secretions cannot be effectively contacted can be avoided.

Description

technical field [0001] The invention relates to the technical field of double-lumen tube intubation, in particular to a multi-functional double-lumen tube intubation which is beneficial to perioperative airway management. Background technique [0002] The double-lumen tube is mainly used for surgical procedures that require one-lung ventilation and isolation of both lungs. During conventional surgical procedures, secretions (bacteria) containing cancer (bacteria) often seep and gather at the end of the lumen of the double-lumen tube (local blood in sputum lesions) In order to avoid the distal spread of cancer (bacteria) secretions, it is necessary to promptly insert the corresponding type of sputum suction tube to fully absorb the suction; under normal circumstances, the double-lumen tube is in the shape of the airway without turning and twisting, and the conventional suction is relatively smooth. There is no special risk for airway management; however, for patients with spe...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a device with reasonable design and simple structure, which does not need to disconnect the long and short breathing tubes from the ventilator when it attracts the secretions of the respiratory tract, which is not easy to fill or block, and can avoid conventional breathing tubes. Suction can not effectively contact the secretions, resulting in ineffective suction and respiratory negative pressure damage caused by repeated attempts to ineffective suction; when complex operations need to be changed from double-lumen tubes to single-lumen tubes, re-intubation is not required to avoid Injury to the patient caused by reintubation, reduce the risk of reintubation and double lumen tube with nasal cannula guide groove
