Tracheostoma Neck Patch With Flexible Film and Supporting Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck patches for tracheal cannulas and artificial noses with speaking valves suffer from poor respiratory activity and wearing comfort due to their rigid plastic disks and increased overall height, which compromises sealing and patient comfort.
Innovation Solution
A thin, planar, flexible film neck patch with a centrically arranged hard plastic disk and a supporting frame, designed to maintain flat positioning, provides excellent sealing and respiratory activity while minimizing overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hard plastic disk with foam material is used for structural support, then the structural stability is improved, but the overall height increases and respiratory activity decreases
Solution Approach 1:
The neck patch is divided into distinct functional layers: a thin flexible film base layer (5-30 μm) for respiratory activity, a supporting frame for structural stability, and a hard plastic disk for device attachment. This segmentation allows each layer to optimize its specific function without compromising others.
Solution Approach 2:
The base layer uses a flexible film with thickness of 5-30 μm that provides respiratory activity while maintaining structural integrity. The film's flexibility allows it to conform to the tracheostoma surface, and when adhered properly, it provides adequate support without the need for thick foam materials.

If a thin flexible film is used to improve respiratory activity, then the respiratory activity is improved, but the structural stability decreases
Solution Approach 1:
The neck patch is divided into distinct functional layers: a thin flexible film base layer (5-30 μm) for respiratory activity, a supporting frame for structural stability, and a hard plastic disk for device attachment. This segmentation allows each layer to optimize its specific function without compromising others.
Solution Approach 2:
The neck patch combines different materials with complementary properties: a flexible film (5-30 μm thick) for respiratory activity, a supporting frame for structural stability, and a hard plastic disk for device attachment. This composite structure allows each material to perform its optimal function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances respiratory activity and wearing comfort by ensuring a low-profile, secure adhesion and effective sealing on the tracheostoma, improving the support for attached devices without the discomfort of rigid components.
Implementation Method 1
The adhesive film above the hard plastic disk is designed as a patch comprising a holding ring for cannulas, valves, filters, etc. The patch can be bonded to the patient's skin.
Implementation Method 2
The film is an elastomer film, for example made of TPU (thermoplastic urethane) or TPE (thermoplastic polyethylene).
Implementation Method 3
a supporting frame that surrounds the outer edge of the film and is approximately five to ten times thicker than the film so that the neck patch can be positioned without being rolled together, i.e., the film is retained in flat or planar form by the frame.

AI summary
There is provided a neck patch to be adhered on a tracheostoma, which is very light and has a good respiratory activity and an excellent sealing behavior when adhered on top of a tracheostoma in the neck of a patient. The neck patch is made of a thin, planar, flexible foil having a thickness of between 5 and 30 μm, which is adhesive on its proximal side only and has a centrically arranged hole on its distal side, and around which a hard, round plastic connector disk having a central recess is arranged, the neck patch further comprising a supporting frame that surrounds the outer edge of the film and is approximately five to ten times thicker than the film so that the neck patch can be positioned without being rolled together.
