Double-cavity bronchial catheter capable of manually adjusting bending direction of auxiliary breather pipe

Abstract

The invention relates to the technical field of medical equipment, and in particular relates to a double-cavity bronchial catheter capable of manually adjusting the bending direction of an auxiliary breather pipe. The double-cavity bronchial catheter comprises a catheter, a first breather pipe and a second breather pipe which are all hoses, wherein the first breather pipe and the second breather pipe are inserted into the catheter; a catheter air bag is arranged on the outer side of one end of the catheter; a breather pipe airbag is arranged at one end, close to the catheter airbag, of the first breather pipe; the catheter air bag and the breather pipe air bag respectively communicate with inflation valves; sections, located at two ends of the breather pipe air bag in the airflow directionof the first breather pipe, of the first breather pipe are respectively a first half-corrugation swing section and a second half-corrugation swing section; a first pull rope component is arranged onthe first half-corrugation swing section; a second pull rope component is arranged on the second half-corrugation swing section; and one end, far away from the catheter air bag, of the catheter is provided with a locking component. The double-cavity bronchial catheter can be smoothly inserted into the left (right) bronchus, accordingly, injury to the inner wall of the trachea can be reduced, postoperative recovery can be facilitated, and infection risks can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a double-lumen bronchial catheter for manually adjusting the bending direction of an auxiliary ventilator. Background technique [0002] Double-lumen bronchial catheter, this product is used for thoracic surgery. During thoracic surgery, the unilateral lung is used to ensure breathing, and at the same time, it also prevents the diseased unilateral lung from infecting the other lung. The side channel of the existing double-lumen bronchial catheter The trachea itself is curved. When the catheter is inserted into the airway, the auxiliary ventilator is rotated and then inserted into the left (right) bronchus to align it for left or right bronchus insertion to confirm that the airway of the left or right lung is unobstructed , has the following disadvantages: [0003] Since the conventional auxiliary ventilator is curved, its end enters against the inner wall of the trache...
