Device for selective bronchial intubation and separate lung ventilation, particularly during anesthesia, intensive therapy and reanimation

摘要

The device comprises: a tracheal tube insertable into the trachea of a patient, and an endobronchial tube, of greater length than the tracheal tube and being insertable into the tracheal tube for reaching, with one of its extremities, one of the principal bronchi. In this way the endobronchial tube defines in co-operation with the tracheal tube a single air passage. At their external ends, the cited tubes are connectable to an air supply and at their internal ends are provided with sealing members which can be actuated to form a seal with the internal walls of the organs wherein the tubes are inserted. There are also provided stoppers adapted to act between the two tubes, towards the exterior, to prevent external communication with the cited air passage. The cited air passage and the endobronchial tube have substantially equal fluid-dynamic resistances to obtain uniform ventilation of both lungs.
