Description

Air passage isolation device for operation Technical Field The application relates to the technical field of bronchial treatment equipment, in particular to an airway isolation device for operation. Background In the prior bronchoscope treatment operation, in order to avoid the problem that the excessive oxygen concentration causes fire during laser treatment of the treatment mirror when the air passage is oxygenated, the air passage of a patient is burnt, and the oxygen content needs to be frequently reduced during the treatment process, so that the serious hypoxia problem of the patient occurs. In the patent number CN213697095U, a plugged bronchial catheter device capable of achieving unilateral plugging is proposed, which can plug a unilateral bronchus and ensure ventilation of the bronchus at the other side, however, the structure can only block blood or pus in the bronchus at the left side and the right side, can not perform affected side cleaning or laser treatment during plugging, has poor clinical effect, and simultaneously, the diameter of the bronchus gradually reduces along with the penetration of the bronchus at the left side and the right side, so that the affected side is difficult to be treated.
