Infant Respirator Fixing Module with Five-Point Strap System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respirator systems for newborns suffer from poor fixation, leading to nasal pressure sores, slippage of nasal tubes, and discomfort, which can affect treatment efficacy and cause conditions like apnea and bradycardia due to inadequate securing mechanisms, and lack the ability to accommodate nasogastric tubes or respiratory sensors.
Innovation Solution
A respirator fixing module comprising a cap, first, second, and third straps, along with a nasal mask structure, provides multiple fixing points to secure breathing tubes and nasal masks, including nasogastric holes for convenient feeding and monitoring, enhancing comfort and stability by distributing the weight and pressure across the infant's head and nose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional nasal tube is used without additional fixing mechanisms, then the device structure remains simple, but the fixation is poor leading to slippage and nasal pressure sores
Solution Approach 1:
The fixing module is divided into multiple independent components: a cap for the head, a nasal mask structure, a first strap connecting the mask to the head, a second strap connecting the cap to the mask, and a third strap providing additional stabilization. This segmentation allows each component to perform a specific fixing function, improving overall fixation reliability while keeping individual components simple and manageable.
Solution Approach 2:
The invention merges multiple fixing functions into a single integrated module that combines the cap, nasal mask, and three straps working together. This unified structure provides five-point fixation (two points from the first strap, two points from the second strap, and one point from the third strap) simultaneously, ensuring both the breathing tube and nasal mask remain securely positioned without requiring separate fixing devices.
2Reliability
If the nasal tube is not fixed to the cap, then the device is easier to wear, but the tube may shift or fall off during infant activities
Solution Approach 1:
The cap is pre-fixed to the infant's head before the nasal mask is attached. The second strap connects the cap to the nasal mask, establishing a stable base structure in advance. This preliminary fixation ensures that when the infant moves or becomes active, the breathing tube remains securely positioned because it is anchored to the already-fixed cap, preventing slippage while maintaining comfort.
3Adaptability or versatility
If traditional nasal tube design is used, then the manufacturing is simple, but there is no possibility of installing nasogastric tube or sensor
Solution Approach 1:
The nasal mask structure is designed with a communicating pipe that can accommodate multiple functions: it serves as the primary breathing tube channel and also provides mounting capability for nasogastric tubes and respiratory sensors. This universal design allows the same basic structure to support various medical interventions without requiring separate fixation devices, enhancing adaptability while maintaining manufacturing simplicity through the use of standard strap and mask components.

AI summary
A respirator fixing module applied to a breathing tube includes a cap, a nasal mask structure, a first strap, a second strap, and a third strap. The cap has a first joint; the nasal mask structure has a nasal mask, two first assembling members and a second assembling member extending from the left, the right, and the top sides of the nasal mask respectively, and a communicating pipe and a breathing tube connected to each other; the first strap is installed between the two first assembling members and encircled into a headband; the second strap is connected to the cap, and the second strap has an end surrounding the breathing tube and a second joint adjustably combined with the first joint; and the third strap has an end fixed to the second assembling member and the other end having a third joint adjustably combined with the first joint.
