1. A device for feeding into a patient'"'"'s jejunum, comprising:

  • a. an elongate, jejunal feeding tube, including an outer extension from the patient'"'"'s stomach, the tube having a feeding inlet end mounted on the outer extension and a perforated outlet end positioned within the patient'"'"'s stomach;

    b. an inflatable balloon structure mounted around the tube and positioned near the outlet end of the tube;

    c. an inflation valve mounted near the inlet end of the tube;

    d. a valve line connected to the valve and providing an outlet port within the balloon structure, the valve line being positioned adjacent the feeding tube;

    e. a closure plug for the feeding inlet and secured to the feeding tube by an integral band; and

    ,f. a locking ring positioned medially along the outer extension of the tube, and sized to frictionally engage the tube and slidably mounted therealong, and adjustable solely by frictional engagement with the tube to accommodate to the size of the wearer, the locking ring providing a plurality of perforations and spaced ridges to enable air circulation between the locking ring and patient'"'"'s body;

    whereby,i. when the balloon is deflated, the feeding tube may be inserted through a stomach placed stoma and into the patient'"'"'s jejunum;

    ii. when the balloon is inflated through the valve and valve line, it will secure the device within the patient'"'"'s stomach and form a seal adjacent the stoma;

    iii. securement of the ring to the tube being provided solely by frictional engagement therebetween, to secure the device within the patient'"'"'s body and to prevent undesirable movement of the ring along the tube, whether in the dry state or when lubricated by body fluids, the locking ring being manually adjustable along the tube to accommodate to the size of the patient, and the balloon and ring both functioning to maintain the device in place in the patient;

    iv. retraction of the ring being entirely against the force of frictional engagement to enable the stoma and adjacent areas to be cleaned; and

    ,v. when the balloon is deflated, retraction of the ring enables the device to be removed from the patient.
