  • Feeding tube facilitating improved placement and permitting subsequent delivery of a second prescribed product and method therefor
    Patent number: 4874365
    Abstract: A naso-gastric feeding tube (10) includes a hollow, flexible tube (12) having an open, proximal end (14) permanently secured to a hollow adapter (16), forming an integral unit. A stylet (56) is removably mounted within the stylet port (42) of the adaptor (16). A syringe (72) may be secured to the placement port (44) in order to conduct the placement confirmation test to assure proper insertion of the feeding tube within the patient, eliminating the need for removing and then reinserting the stylet to confirm proper insertion of the feeding tube (10). Additionally, the feeding tube (10) permits delivery of a second prescribed product without disconnecting the tube (10) from the source of the first prescribed product.
