Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intraosseous devices face challenges in maintaining stability and preventing movement relative to the patient's skin, particularly when connected to a fluid source, which can lead to displacement and instability.
Innovation Solution
The proposed solution involves a stabilizer apparatus comprising two coupled members with adhesive tabs that encircle an intraosseous device, resisting movement by contacting a resilient barb with a ledge and using flexible tabs with adhesive layers to secure the device to the patient's skin, ensuring stability even when connected to a fluid source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the intraosseous device is connected to a fluid source, then fluid delivery function is improved, but device stability deteriorates due to movement and displacement
Solution Approach 1:
The stabilizer is divided into multiple independent members (first member, second member, third member) that can be coupled together in different configurations. Each member can be independently positioned and coupled to the intraosseous device at different locations, allowing the stabilizer to adapt to various device positions while maintaining stability. This segmentation enables the system to accommodate fluid source connections without compromising stability.
Solution Approach 2:
The stabilizer members are designed with flexible properties and can be coupled together in dynamic configurations. The members can be positioned at different orientations and coupled together to form a stable structure that adapts to the specific needs of the intraosseous device and fluid source connection. This dynamic capability allows the stabilizer to maintain stability while accommodating various operational requirements.
2Stability of the object's composition
If the stabilizer members are rigidly fixed, then device stability is improved, but ease of operation deteriorates due to difficulty in positioning and coupling
Solution Approach 1:
The stabilizer members are designed with flexible properties that allow them to be easily positioned and coupled together. The members can be bent and shaped to accommodate different intraosseous device positions, and their flexible nature enables simple coupling mechanisms. This dynamic flexibility significantly improves ease of operation while maintaining stability once the members are coupled together.
Solution Approach 2:
The stabilizer members can be configured in different physical states and orientations. The members can be bent, angled, and positioned at various orientations before being coupled together, allowing for easy positioning and adjustment during operation. This parameter flexibility enables operators to easily adapt the stabilizer to different device positions and requirements.
3Reliability
If the stabilizer uses multiple coupling mechanisms, then reliability is improved, but device complexity increases
Solution Approach 1:
The stabilizer is divided into multiple members, each with its own coupling mechanism. By segmenting the stabilizer into separate components, each coupling mechanism can be simple and straightforward, while the overall system achieves high reliability through the combined effect of multiple couplings. This segmentation allows for simple individual mechanisms that collectively provide secure attachment.
Solution Approach 2:
Multiple stabilizer members are coupled together to form a single functional unit. The coupling mechanisms are designed to be simple and straightforward, but when multiple members are combined through these simple couplings, the overall system achieves high reliability. The merging of multiple simple couplings provides robust attachment without requiring complex individual mechanisms.

AI summary
Stabilizers for intraosseous devices, such as, for example, stabilizers that may be coupled to an intraosseous device (e.g., a device including an intraosseous needle) while a portion of the device extends into a patient's bone and/or while the device is coupled to a fluid source (e.g., IV bag, syringe, etc.).
