Proactive Use of the TubeClear System Assists Optimum Therapy Delivery

Enteral access devices (EADs;  feeding tubes) provide vital nutrition, medication, and hydration to more than seven million patients annually [1].  Interruptions to the delivery of enteral therapy has been found to increase the patient’s caloric deficit and their hospital length of stay[2], greatly increasing the overall cost of care.

The TubeClear System, a device developed to clear clogged or sluggish feeding tubes to restore or maintain their patency, could help prevent interruptions to delivery of enteral therapy when used proactively.  A recent bench test found promising results.[3]

Bench studies suggest that, when used correctly and proactively (i.e. before a feeding tube becomes completed clogged), the TubeClear System is 145.6% more effective at removing built-up material along the walls of the feeding tube than the standard practice of flushing a tube with water. As material builds up along the inside walls of the feeding tube, it can gradually restrict the flow of nutrition. 

Actuated Medical, Inc. (AMI) tested the use of the TubeClear System on partially clogged feeding tubes.  For this test, 22 feeding tubes were used; the patency of 11 tubes was maintained with the standard practice of water flushing, and the patency of the other 11 tubes was maintained with the TubeClear system.  A weight was recorded for each empty feeding tube before it was clogged.  The clog contents included a combination of feeding formula and fiber supplements, to simulate types of clogs observed in a clinical setting, and clogged feeding tubes were then heated to ensure consistency between the tubes. Each clogged tube was weighed and received a water flush. 

For the first 11 feeding tubes, only water was used for clearing the tube.  After treatment, they were weighed again.  On average, flushing the partial clog with water increased the weight of the feeding tube by 68.5%, indicating that the moisture may have been absorbed by the build-up.

The second 11 feeding tubes were treated with the TubeClear System after the initial water flush.  On average, those feeding tubes decreased in weight by 77.1%, suggesting more of the occlusion material was removed than the tubes treated with water alone. 

These results suggest that the TubeClear System is more effective at clearing partial clogs than the standard practice of flushing with water alone.  AMI recommends using the TubeClear System at least once per week for optimum therapy delivery.  If the flow within the feeding tube is sluggish in the meantime, indicated by a feeding pump alarm or when it’s difficult to flush with water or administer medication, it is appropriate to use the TubeClear System more frequently, as needed.

TubeClear System Clears Clogged Tubes: Various Compounds

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). Reported clogging rates vary, ranging from 9-35% (1, 2).

Attempts to clear clogged feeding tubes using various techniques are time-consuming and often result with tube replacement still being required. Also, many of the current methods only work on certain types of clogs. For example, most enzyme treatments are only applicable to protein (feeding formula) based clogs. Among common emergency room medical procedures, patients rank nasoenteral (NE), (nasogastric [NG]) tube insertion to be one of the most painful (4, 5, 6). Replacing a feeding tube may cause additional patient safety risks, associated medical costs, and additional pain and discomfort to the patient. The most common way to place NE (NG) feeding tubes, is blind insertion at patient bedside, and has a reported 0.5-15% malposition rate (3). Malposition into the trachea may cause pneumothoraxes and possibly death. Several methods exist for verifying accurate tube placement, the most reliable being radiography (3). However, this exposes patients to additional radiation and medical costs.

Taking into account nursing time, tube replacement, radiographs and other miscellaneous costs, the capability to clear a clogged feeding tube while it remains in the patient, could represent substantial savings to a medical facility not to mention reduced pain and discomfort to the patient. For patients outside the hospital, a clogged feeding tube often results in transportation and admission costs to the payer and anxiety to the patient.

The TubeClear System was developed to efficiently and effectively clear clogged feeding tubes while the tube remains in the patient (7). It is currently FDA cleared to unclog 10-18 Fr NE, NG, gastrostomy (G [including percutaneous endoscopic gastrostomy, PEG tubes]) and jejunostomy (J) feeding tubes in adults at bedside while the tube remains in the patient. The TubeClear System is also CE marked. The TubeClear System is comprised of a reusable Control Box to which a single-use Clearing Stem is attached. The Clearing Stem is inserted into the patient’s feeding tube by the licensed healthcare practitioner. The Clearing Stem moves backward and forward, and the tip works against the clog to mechanically disrupt and clear the feeding tube.

TubeClear System Clears Clogged Tubes: NE, G, J Tubes

Individuals unable to ingest nutrition and/or medication orally for various causes, often become dependent on enteral nutrition as a life-saving mechanism (1). However, due to daily administration of feeding formula and/or medication, as well as other unknown causes, these medically needed feeding tubes may become clogged, up to 35% of the time (1, 2).

Clogged feeding tubes often result in the interruption of a patient’s nutrition and medication regimens, representing a burden to both caregivers and patients. Attempts to clear clogged feeding tubes using various techniques are time-consuming and as a result cause delays in feeding, hydration, and medications which can have negative effects on overall patient health and healing (3). Often, these tube clearing methods fail and the tube requires replacement, exposing patients to both additional radiation from placement confirmation (x-rays) and increased medical costs. Notably, among common medical procedures, patients rank nasoenteral (NE), (nasogastric [NG]) tube insertion to be one of the most painful (4, 5, 6). The most common way to place NE (NG) feeding tubes, is blind insertion, and has a reported 0.5-16% malposition rate (7). Malposition into the trachea may cause pneumothoraxes and possibly death, though several methods exist for verifying accurate placement, the most reliable is radiography (7). Replacing clogged gastrostomy (G) and jejunostomy (J) feeding tubes may require additional endoscopic guidance or surgical procedures depending on tube type.

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 and clear the clogged feeding tube (8). It is currently FDA cleared to unclog 6-18 Fr NE, NG, G (including percutaneous endoscopic gastrostomy, [PEG tubes]) and J tubes while the tube remains in the patient.

TubeClear System Clears Clogged Tubes at Bedside: Clinical Case Study

Feeding tubes are used to deliver enteral nutrition to patients that are unable to ingest nutrients and medications orally and therefore are at risk of malnutrition and dehydration (1).

Unfortunately, the long and narrow inner lumens of small bore feeding tubes used to deliver enteral nutrition and medication to patients often clog for various reasons including, delivery of high viscosity medications, by chemical reactions between feeding formula and medication, or by inadequate tube maintenance (2,3). Clogged feeding tubes can cause patients to go extended periods without nutrition and medication, and attempts to unclog tubes strain

valuable nursing resources. Traditional methods to clear clogged feeding tubes are often unsuccessful, potentially leading to tube replacement, and patient discomfort (2,3,4).

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 motion of the Clearing Stem Tip acts to mechanically disrupt and clear the clogged materials from the feeding tube (5).

An in human case series was completed, documenting twelve cases in which TubeClear was used to clear clogged nasoenteral (NE) feeding tubes. All documented cases were completed by a single licensed healthcare practitioner and were 100% successfulwithout any issues reported by the practitioner and/or patients. The ability to quickly clear clogged feeding tubes while the tube remains in the patient will save healthcare resources, and ease the burden on patients and caregivers.

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.
