FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to systems for extending narrowed part of patient's respiratory ways. System contains catheter tube with total length from 35 to 70 cm, lumen for probe and lumen for blowing, blowing balloon, located along distal part of catheter tube and connected with lumen for blowing; and probe, projecting beyond distal end of catheter tube, when probe is placed inside lumen for probe. Proximal part of probe is less flexible than distal part, with distal part being bendable and capable of preserving curved configuration when placed inside lumen for probe. Distal part of probe has higher level of rigidity than distal part of catheter tube, so when distal part of probe is bent, said bent distal part makes distal part of catheter tube bend when probe is placed inside it.EFFECT: application of invention makes it possible to increase convenience of system introduction and holding in case of extension of narrowed parts of respiratory ways.24 cl, 10 dwg |
