Abstract

The invention relates to a double-lumen catheter device capable of adjusting single-pulmonary ventilation volume and positive airway pressure, comprising a main catheter and an operation side catheter and a non-operation side catheter, wherein one end of the main catheter, one end of the operation side catheter and one end of the non-operation side catheter are connected by a first Y-shaped catheter to form a tee structure; the other end of the non-operation side catheter is connected with a non-operation side catheter port; the other end of the operation side catheter is connected with an operation side catheter port; an operation side catheter body is provided with a two-way two-channel flow control mechanism capable of adjusting and controlling the ventilation volume and the positive airway pressure of the operation side catheter; and the other end of the main catheter is connected with a medical machine port. The invention has strong adaptability and wide application, can simplifythe anesthesia management so as to enable the anesthesia to be safer, and can effectively prevent complicating diseases of hyoxemia and the like caused by operation cannula while providing a relatively static operation field.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a double-lumen endotracheal tube device with adjustable single-lung ventilation and positive airway pressure. Background technique [0002] Patients undergoing thoracotomy usually take the lateral position, and the thoracic cavity on the operating side is located above. In order to facilitate the exposure of the surgical field, anesthesiologists always use a double-lumen bronchial catheter to intubate the lung on the operating side to maximize the benefit of the surgical operation. . Although the ipsilateral pulmonary vascular resistance increases after the operation side lung collapse, coupled with the hypoxic constriction of the pulmonary blood vessels caused by the operation side alveolar hypoxia, can reduce the occurrence of intrapulmonary shunt to a certain extent. However, many patients still develop hypoxemia due to excessive blood flow to the operated lung that cannot be o...
