Many patients rely on enteral nutrition, where liquid food is delivered directly to the stomach or intestines via a tube. Traditionally, “closed systems” are safer and more sterile but require expensive, specialized containers. Carton packages—common and affordable—aren’t compatible with these closed systems and pose risks: unfiltered air can contaminate the product, and liquid can soak into the cardboard, weakening it and possibly causing spills or detachment.
Core Features
This invention introduces a low-cost, high-safety closure device that lets ordinary carton packages be used in closed enteral nutrition systems. It includes:
- A secure connector compatible with standard medical tubing.
- A built-in biological air filter that only allows clean air in.
- A clever glue-sealed assembly that not only sticks the device to the carton but also seals the exposed cardboard edges from contact with liquid.
Inventive Step
Unlike older designs that require costly ultrasonic welding or special adhesives to attach air filters, this invention uses the same glue that attaches the device to also secure and seal the filter. This dual-purpose glue creates a primary and secondary seal, ensuring safety while drastically lowering costs. A flexible internal part also helps widen the air passage when the device is used, improving flow.
Benefits
- Reduces production costs of medical packaging.
- Prevents contamination and leakage.
- Enables the use of cheaper, widely available carton packaging for closed systems.
- Compatible with multiple tube connector types.
Broader Impact
This invention makes closed enteral feeding systems more affordable and safer, especially for home care patients or under-resourced hospitals. It promotes better hygiene, reduces packaging waste, and improves global access to essential medical nutrition delivery.
