  • Patent number: 4205676
    Abstract: Method and apparatus for force-feeding a patient despite a swallowing impairment is disclosed and includes a feeding tube which may be passed through the patient's nasal cavity and by way of the pharynx sufficiently far into the stomach to allow foodstuff or like material emanating from the tube to enter the patient's stomach. The feeding tube extends from a material outlet on a dispensing container which has a further air inlet. The material may be placed in the container so that upon increasing the air pressure within the container, material is forced therefrom by way of the tube to the patient. A source of air at a pressure greater than the ambient atmospheric pressure provides the pressure increase and includes a bleeder valve for regulating the rate of air flow from the pump to the container thereby also regulating the material flow through the tube.
