Feeding-Tubes TRIZ Cases

Distinct suction ends let multiple people share one beverage straw while reducing germ transmission and avoiding separate straws.

A shape-memory wire lets the tube stay narrow during insertion, then expand at body temperature for easier feeding and less nasal compression.

A buoyant ball valve vents stomach gas back into the feeding container, reducing manual aspiration in neonatal gravity feeding.

A tapered tip and flange split the coupling into fixing and stress-free zones to resist rupture while keeping enteral line connection easy.

Inflatable outer lumens compress the feed lumen to dislodge debris and flush occlusions, keeping GJ tubes patent without manual clearing.

A peristaltic filling approach helps an elastomeric enteral feeding pump stay quiet, easier to fill, and more discreet in public.

A timer-controlled valve automates gravity flow testing to reduce human timing error when checking liquid food viscosity for dysphagic patients.

An ear hook and inflatable gastric balloon stabilize the tube against premature removal while allowing controlled detachment when needed.

A bypass path lets enteral feeding lines fill quickly, while a check valve maintains controlled delivery and prevents backflow.

Redirects nutrient-rich gastric fluids from the stomach to the jejunum through an external conduit, preserving electrolytes during gastric drainage.

The Shore-hard polyurethane envelope lets the chamber pass through the esophagus deflated, then retain shape to block reflux.

This percutaneous feeding catheter uses a stretchable section and retaining structure to accommodate movement while limiting leakage risk.

One connector links wide-mouth containers, syringes, and enteral tubing.

A tapered tube with stiffness variation and lubricious coating supports flow while easing placement and removal.

Segmented adhesive portions on a stabilization clip enable staged removal, reducing patient discomfort and preventing accidental tube dislodgement.

Segmenting the base with a curved recess improves device stability while preventing stoma irritation caused by moisture buildup.

Constant diameter nozzle with circumferential indentations prevents misconnection and reduces wear on elastomeric sealing rings.

Peripheral vacuum lumens seal the esophagus wall to prevent gastric reflux and aspiration pneumonia while maintaining enteral feeding capability.

Helical wire coils secure organ walls to abdominal tissue, preventing accidental removal while maintaining reliable feeding access.

Segmented locking elements within an elastomeric cap prevent accidental unlocking from user movements while maintaining secure connection stability.

Slit lamellae in the gastrostomy tube bulb stretch via a mandrel to pass the stoma, then spring back to prevent accidental deformation during use.

A securement assembly stabilizes enteral and vesical access devices using a pivotable lid that transfers compression force to the central portion.

A fistula catheter uses a right-angle flexible tube body linked to an external fixing member for fluid flow.

Integrating a passive electromagnetic sensor into a feeding tube enables real-time MRI tracking while minimizing RF induced heating risks.

A jejunostomy tube features a lateral opening that diverts gastrointestinal fluid through an afferent and efferent limb pathway.

A twin port adapter with a rotatable eccentric bearing manages fluid flow in enteral feeding pump systems.

A philtrum-mounted fixing device secures double-tube intubation using a detachable pressing frame with interlocking latches.

Relocating female threading to an outer spiral protrusion eliminates nutrient-trapping valleys while maintaining secure clamping force.

Radial external bolster extension anchors PEG tube while reducing tissue irritation at stoma site.

An OstoPump system connects proximal and distal ostomies with a peristaltic pump to enable enteral feeding, replacing intravenous nutrition.

Peripheral vacuum lumens decompress gastric gas and prevent reflux, reducing aspiration pneumonia risk.
