Description

  The subject matter of the present disclosure relates to a delivery tube assembly that includes systems and techniques for placing a percutaneous tubing into a patient.

  Certain delivery tube assemblies, including those for enteral and parenteral indications, are known and used in the medical art. For example, percutaneous endoscopic gastrostomy (PEG) is an endoscopic medical procedure in which a tube ("PEG tube" or "G tube") passes through the abdominal wall, such as the patient's stomach, etc. Placed in the gastrointestinal system. PEG tubes can be used to treat or nourish patients when oral intake is not appropriate (eg, due to dysphagia or sedation). PEG tubes can also be utilized to dispense medication through the tube, for example, if the beneficial absorption of the medication is not appropriate for oral administration. The tubing system may be used, for example, by passing a jejunal extension tube ("PEG-J tube" or "J tube") through a PEG tube and through the pylorus into the jejunum to bypass the stomach and dispense the jejunum directly. And may be further extended into the gastrointestinal system such as the small intestine.

  PEG can involve drilling a hole in the abdominal wall, forming a fistula, and feeding a G-tube through the fistula into the stomach. The J-tube can be fed through the stomach and duodenum into the jejunum through the G-tube. An inner bumper can be placed inside the stomach and mounted around the G-tube, for example, to prevent or prevent the G-tube from moving out of the stoma.

  The piping system may include an outer bumper fixed to the G-tube and positioned on or near the skin, for example to protect the fistula and guide the G-tube and J-tube exiting the fistula . The outer bumpers can also prevent or prevent the outer portions of the G and J tubes from moving through the fistula and into the stomach. Additionally or alternatively, the tubing system may be at the end of the outer portion of the G and J tubes, for example, to facilitate attachment of the G and J tubes to external devices such as food or drug delivery devices. It may include an attached patient side connector. The patient side connector can also facilitate cleaning of the G and J tubes, including washing each tube separately.

  However, there is still a need for further improvement of known percutaneous piping systems, such as PEG-J piping systems. For example, it may be desirable for the connector to provide a simple connection to an external device while also preventing or preventing accidental disconnection and / or movement of the J-tube. Also, it may be desirable for bumpers to allow flexible movement and rotation of G and J tubes. For example, to facilitate proper fistula treatment while also allowing the G and J tubes to be approximately flat and parallel to the abdominal cavity, the G and J tubes may be placed in the stomach outside the fistula. It may be even more desirable for the bumper to guide generally perpendicularly to it. This may reduce the visibility of the tube. These and other advantages may be provided by the piping system and method in accordance with the disclosed subject matter.
