| 摘要 |
A tubular, flexible and elongate device, which has at least one distal orifice and at least one proximal orifice, for replacing a respiratory probe which is already in place in the trachea of a patient, and which is supplied with respiratory assistance gas via at least one main supply conduit with another respiratory probe external to the patient. The device may be introduced into both of the respiratory probes, and may be connected via its proximal orifice to an auxiliary conduit for supplying respiratory gas at a higher pressure than that of the main supply conduit.
