| 摘要 |
Several developments for tubular intubation devices are disclosed. In one development, the intubation device has over at least a portion of its length two opposed wall sections which are of lesser thickness than the wall sections by which they are connected. As a result, the device has a greater degree of transverse flexibility about the reduced wall thickness sections than about the wall sections of greater thickness. Intubation devices may be provided with balloons which are of an elastomeric polyurethane. Pressure within a balloon on the intubation device may be monitored by a pressure indicator device having a bellows working within a transparent housing. The position of the bellows provides an indication of the pressure. An arangement for supporting a tracheostomy tube on the neck of a patient is also disclosed. |
