Description

The subject matter of this disclosure relates to a transport tube assembly, including systems and techniques for placing percutaneous piping within a patient.

Certain transport tube assemblies are known and used in medical art, including those for intra- and extra-intestinal indications. 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. Placed within the gastrointestinal system of. PEG tubes can be utilized to treat or nourish a patient if oral ingestion is not appropriate (eg, due to dysphagia or sedation). PEG tubes can also be utilized to administer a dosing through a tube, for example, if the beneficial absorption of the dosing is not appropriate for oral administration. The plumbing system, for example, by passing a jejunal extension tube (“PEG-J tube” or “J tube”) through the PEG tube and into the jejunum through the pylorus, for example to bypass the stomach and administer the jejunum directly. , Can be further extended within the gastrointestinal system such as the small intestine.

PEG can involve drilling a hole in the abdominal wall, forming a fistula, and supplying a G-tube into the stomach through this fistula. The J-tube can be supplied through the stomach and duodenum into the jejunum through the G-tube. The medial bumper can be placed inside the stomach and attached around the G-tube, for example to prevent or prevent the G-tube from moving out of the fistula.

The plumbing system may include an outer bumper secured to the G-tube and placed on or near the skin near the fistula, for example to protect the fistula and guide the G-tube and J-tube exiting the fistula. .. The outer bumper can also prevent or prevent the outer portion of the G-tube and J-tube from moving through the fistula into the stomach. Additional or alternative, the plumbing system is at the end of the outer portion of the G-tube and J-tube to facilitate attachment of the G-tube and J-tube to external devices such as food or drug transport devices. It may include an attached patient-side connector. The patient-side connector can also facilitate cleaning of the G-tube and J-tube, including cleaning each tube separately.

However, there are still requests for further improvements in known percutaneous piping systems such as the PEG-J piping system. For example, it may be desirable for a connector to provide a simple connection to an external device while preventing or preventing accidental disconnection and / or movement of the J-tube. It may also be desirable for the bumper to allow flexible movement and rotation of the G-tube and J-tube. For example, the G-tube and J-tube are placed outside the fistula into the stomach to facilitate proper fistula treatment, also allowing the G-tube and J-tube to be placed approximately flat and parallel to the abdominal cavity. It may be even more desirable for the bumper to guide it approximately vertically. This may reduce the visibility of the tube.
