Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] Such as Figure 1-3 As shown, a three-chamber bronchial intubation tube capable of ultrasonic lung lavage in the present invention includes a cannula body 1, and a main blocking bag 2 is set on the outside of the cannula body 1, and the main blocking bag 2 is connected with Main inflation conduit 3. The main inflation catheter 3 is connected with a main balloon 4 at one end away from the main blocking bag 2, and the main blocking bag 2 is inflated by squeezing the main balloon 4 during use to expand the main blocking bag 2, and the main blocking bag 2 is inflated. The sac wall of the blocking sac 2 is in close contact with the trachea to close the trachea to ensure that the inside of the lung is in a sealed state.

[0016] The cannula body 1 includes a ventilation tube 5, a liquid outlet tube 6 and a liquid injection tube 7, the liquid outlet tube 6 and the liquid ...

Abstract

The invention discloses a three-cavity bronchial cannula for practical ultrasonic lung lavage. The cannula comprises a cannula body, a main plugging capsule is arranged on the outer side of the cannula body in a sleeving manner and connected with a main inflatable catheter, one end, far away from the main plugging capsule, of the main inflatable catheter is connected with a main spherical capsule,the cannula body comprises a ventilation pipe, a liquid outlet pipe and a liquid injection pipe, a ventilation opening is formed in the top of the ventilation pipe, a liquid outlet is formed in the top end of the liquid outlet pipe, a liquid injection opening is formed in the top end of the liquid injection pipe, two auxiliary plugging capsules are arranged on the outer sides of the lower ends ofthe liquid outlet pipe and the liquid injection pipe in a sleeving manner, each auxiliary plugging capsule is connected with an auxiliary inflatable catheter, one end, far away from the correspondingauxiliary plugging capsule, of each auxiliary inflatable catheter is connected with an auxiliary spherical capsule, and ultrasonic generators are arranged at the lower ends of the liquid outlet pipeand the liquid injection pipe and connected with ultrasonic controller connectors through leads.

Description

technical field [0001] The invention relates to the technical field of lung lavage, in particular to a three-chamber bronchial intubation tube capable of ultrasonic lung lavage. Background technique [0002] Lung washing is also called "large-volume whole lung lavage". Under general anesthesia, the patient first blocks the bronchus on one side, connects the ventilator for ventilation, and repeatedly injects and draws out the liquid in the bronchus of the other side of the lung, and then uses the same Methods Lavage the other side of the lung to achieve the purpose of clearing the foreign matter in the alveolar cavity. [0003] The current lung washing process uses the traditional double-lumen bronchial intubation to isolate the lungs. Usually, the conventional double-lumen bronchial intubation only has a single blocking bag, so that the intubation is not fixed firmly and is easy to move. When the pressure in the lung Larger cases may also lead to problems such as lavage flu...
