| 摘要 |
A gastric feeding device for introduction into the stomach of a patient from the nasal or oral opening thereof comprising an elongate flexible collapsible tube having a longitudinal passageway with a wall thickness incapable of independently sustaining a tubular shape in the absence of internal support in the longitudinal passageway, a relatively rigid fitting having a through passageway attached to the proximal end of the collapsible tube for introducing an elongate flexible support tube into the length of the passageway to support the same during intubation, and for introducing a fluid into and throughout the length of the collapsible tube passageway to contact the inner wall surface thereof after intubation to permit removal of the support tube therefrom. The support tube engages the closed distal end of the collapsible tube to maintain the relative positions of the support tube and collapsible tube, and/or a water-soluble adhesive material may be applied to the outer surface of the support tube and inner surface of the collapsible tube to secure the relative positions thereof during intubation. |
