Description

Visual combined bronchial catheter with good stability

Technical Field

The utility model belongs to the field of medical equipment, a bronchial tube that adopts when chest department and other needs carry out lung isolation technique is related to, concretely relates to visual combination formula bronchial tube that stability is good.

Background

When the thoracotomy is performed, the ventilation of the affected lung needs to be stopped temporarily, the healthy lung needs to be ventilated continuously, the operation can be performed conveniently, and in addition, the ventilation of both lungs is needed before or during the operation. Currently, a double-lumen endotracheal tube or a single-lumen endotracheal tube is generally used in combination with a bronchial occluder to achieve the above functions. The existing double-cavity tracheal catheter comprises a left cavity channel and a right cavity channel which respectively correspond to an outlet, two air bags are arranged on the outer part of the double-cavity tracheal catheter from top to bottom, the upper air bag blocks a trachea, and the lower air bag blocks a main trachea on one side. The applicant has partially solved the above problems in both patents CN205360191U and CN 208974896U, and in particular, the latter patent discloses that the practical use of an inner catheter intubation conducted with a cuff core and a bronchofiberscope has been substantially completely overcome.

However, the following are still insufficient: the outer conduit and the shunt tubes are separately arranged, so that the structure is complicated, the connection is long, the operation is not good, and the reduction of ineffective cavities and air duct pressure is not facilitated; whether the insertion depth of the inner tube is proper or not can not be directly observed from the outside, but only can be roughly estimated from the front end of the inner tube or through the scale of the tube wall (currently, the inner tube can be clearly positioned, if the transparency of the inner tube is high, the opening of the contralateral lung can be clearly seen and the rough depth can be judged, but if the inner tube can be observed from the main tube or the outside, the intuition and the positioning accuracy can be further improved, and the two-lumen tube can be respectively seen from two sides after the insertion is finished); when the inner tube is inserted into the right side, the inner tube is too short in insertion distance, sliding displacement is easily caused to cause poor ventilation effect of the upper right lung or a deviation part causes poor collapse effect of the contralateral lung, when the right collateral bronchus is inserted too deeply, only the lower right lung is ventilated, and the insertion is too shallow, so that the upper right lung and the lower right lung can be ventilated simultaneously, however, the interval between the left lung inlet and the upper right lung inlet is only about 2cm generally, the inner tube is clamped in the area through a single air bag, so that the area is not easy to locate accurately, and on the other hand, the single air bag is clamped only at one force point, so that the inner tube is easy to slide and slightly slides to possibly cause ventilation (outer slide) of the left lung or cause ventilation (inner slide) of the upper right lung to be incapable, and the stability is not good enough.
