TubeClear System Clears Clogged NE Tubes: Benchtop Study

Small bore feeding tubes are used to provide essential nutrition and medication to patients at risk of malnutrition and dehydration due to an inability to ingest orally (1). Clogging is one of the most frequent mechanical complications of feeding tubes (2,3). Tubes are more likely to become clogged when powdered, crushed, acidic, or alkaline medications or ground feeding formulas containing particulates are delivered through the small inner lumen, or when tubes are not routinely flushed following feedings (2).

Clearing clogged feeding tubes creates hassles and frustration for practitioners and anxiety and discomfort for patients. The lapse in nutrition and medication regime may also negatively impact recovery (4). Standard techniques for clearing clogged feeding tubes in the past included enzymes, Coca-Cola®, and meat tenderizer. Today, commercially available manual brushes and stylets exist, in addition to enzymes or syringe water flushes (2,5,6). Attempts to clear clogged feeding tubes using these techniques are time-consuming and often result with tube replacement still required. Moreover, among other common medical procedures, patients rank Nasoenteral (NE, nasogastric [NG]) tube insertion to be one of the most painful (7,8,9).

The TubeClear System, an FDA-cleared and CE marked medical device, was developed to clear clogged feeding tubes at bedside while the tube remains in the patient. The system comprises of a reusable Control Box that actuates a single-use Clearing Stem. The Clearing Stem inserts into the feeding tube and the backward and forward movement of the Clearing Stem acts to mechanically disrupt the clog and clear the clogged feeding tube (10).

A bench study was conducted to test the efficacy of three different clog-clearing strategies on in-vitro clogged tubes. Of the three clog clearing strategies tested with artificially clogged tubes, warm water flushes and commercially available enzyme treatments took significantly longer to clear clogged feeding tubes, when compared to the TubeClear System.
