How do Dobhoff-type tube (small-bore, weighted tip), Nasogastric (NG) tube, gastric delivery compare side by side?
The table below compares Dobhoff-type tube (small-bore, weighted tip), Nasogastric (NG) tube, gastric delivery across 11 procurement-relevant dimensions, from what the name means through source.
Side-by-side comparison
| Dimension | Dobhoff-type tube (small-bore, weighted tip) | Nasogastric (NG) tube, gastric delivery |
|---|---|---|
| What the name means | Brand-originated name (manufacturer spelling "Dobbhoff") for a small-bore feeding tube with a weighted tip. The maker itself labels these products "Nasogastric Feeding Tube", and one variant "Naso-Jejunal". | A description of route and target: a tube passed through the nose into the stomach. 21 CFR 876.5980 lists "Nasogastric tube" as an example of a gastrointestinal tube. |
| Tube design | FDA 510(k) K112511 describes the Dobbhoff nasogastric enteral feeding tubes as "small bore enteral access catheters", made with a radiopaque material and a hydrophilic coating, with external markings in centimeters. | The regulation describes gastrointestinal tubes as flexible or semi-rigid tubing used for instilling fluids into, or withdrawing fluids from, the alimentary tract. Sizes of adult NG tubes are covered in the CASRAI NG tube sizes guide. |
| Sizes in manufacturer records | AccessGUDID/openFDA records list 8, 10 and 12 FR tubes, 43 in and 55 in lengths, and a 16 FR x 67 in tube with a 9 FR jejunal tube. | Varies by product. A review of post-pyloric feeding gives 8-12 French for nasoenteric tubes in general. |
| Weighted tip | Records list 5 g and 7 g weighted Dobbhoff tips. A 2009 review states that the advantage of weighted over unweighted tubes is uncertain. | Weighted and unweighted nasoenteric tubes both exist, according to the same review. |
| Stylet (guide wire) | Records list stylet and no-stylet versions. The 510(k) summary says the metal-wire stylet "may be optionally utilized to assist with tube placement". | The review notes nasoenteric tubes are made with and without guide wires. |
| Aspiration profile | In the review, post-pyloric (nasojejunal) delivery gives aspiration risk that is "less frequent but not absolutely prevented". | In the same review table, nasogastric aspiration risk is "high in patients with GER and swallowing impairments". |
| Blockage tendency | The review says nasoenteric tubes tend to be blocked because they are usually longer and of finer bore; its authors advise regular flushing (every 4-6 h in their statement). See the CASRAI feeding tube clog guide. | The review lists clogging as rare for nasogastric tubes, thanks to their larger diameter. |
| Access and feeding mode | The review says nasojejunal feeding needs an endoscope or prokinetic agents, is continuous only, and a pump is mandatory in most cases. | The review lists easy access with no need for endoscopic or radiological study or medication, and a more physiological pattern that keeps normal motility and hormonal profile. |
| FDA classification | Cleared under 510(k) K112511 (Covidien, substantially equivalent, 2012-05-11), tested to EN 1615:2000 and ISO 10993-1:2009. UDI records: product code KNT, 21 CFR 876.5980, class 2, single use. The summary states no clinical evaluations were performed or relied upon. | Same regulation (21 CFR 876.5980, gastrointestinal tube and accessories). The regulation does not define a Dobbhoff tube separately. |
| When each fits (clinician decision) | Small-bore tubes of this kind are among the nasoenteric options the review describes for post-pyloric delivery, which it says reduces the likelihood of aspiration or vomiting. A clinician makes the choice. | Gastric delivery is the option the review describes as easy to access and more physiological, with higher aspiration risk in patients with reflux or swallowing impairment. A clinician makes the choice. |

Common questions
Common questions about Dobhoff-type tube (small-bore, weighted tip) vs Nasogastric (NG) tube, gastric delivery
Is a Dobhoff tube a type of NG tube?
+
Often, yes by labelling. The manufacturer's own product descriptions call these small-bore weighted-tip tubes "Nasogastric Feeding Tube" (one variant is labelled "Naso-Jejunal"). "Nasogastric" describes the route, while "Dobhoff" (manufacturer spelling "Dobbhoff") is a brand-originated name for a tube design. Source: openFDA UDI records, read 2026-10-30.
What sizes does a Dobhoff tube come in?
+
AccessGUDID/openFDA records list 8, 10 and 12 FR tubes in 43 in and 55 in lengths, with or without a stylet, plus a 16 FR x 67 in tube with a 9 FR jejunal tube. Read 2026-10-30.
Does the weighted tip help?
+
A 2009 review of post-pyloric feeding (World J Gastroenterol 15:1281) states that the advantage of weighted over unweighted tubes is uncertain.
Why do small-bore feeding tubes clog?
+
The same review says nasoenteric tubes tend to be blocked because they are usually longer and of finer bore, while clogging is rare in nasogastric tubes thanks to their larger diameter. See the CASRAI guide on feeding tube clogs.
