Catheter Securement Using Deformable Solid Material Without Kinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheter securing devices are often limited to specific catheter diameters and types, requiring multiple purchases, and fail to provide secure fixation without reducing flow rate or causing kinking, while also posing risks of dislocation and contamination.
Innovation Solution
A medical device using deformable solid materials in a base and top element, with a reversible connection mechanism, that can adapt to varying catheter diameters and types, providing secure fixation without pinching and allowing visual inspection, while preventing kinking and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a catheter is secured using a catheter securement device, then the catheter can be fixed to the patient's body, but the patient's skin is exposed to harmful bacteria and pathogens at the insertion site
Solution Approach 1:
The catheter is inserted through the hub of the cap, with the cap serving as a protective outer layer that encloses the insertion site. The cap contains a receptacle that receives the hub, creating a nested structure where the cap protects the skin while allowing catheter access through its center.
Solution Approach 2:
The cap acts as an intermediary component between the catheter hub and the patient's skin. It provides a barrier that prevents direct contact between the skin and harmful factors, while still allowing the catheter to function through the hub penetration.
2Stability of the object's composition
If a catheter is secured using a catheter securement device with a catheter stabilizing member, then movement of the catheter is reduced, but the device complexity increases
Solution Approach 1:
The stabilizing member is configured to be deformable under compression, allowing it to adapt to different catheter positions and movements. This dynamic property enables the stabilizing member to maintain contact and reduce catheter movement without requiring a complex rigid structure.
Solution Approach 2:
The stabilizing member's physical state changes from a relaxed configuration to a compressed configuration when the cap is assembled over the hub. This parameter change enables the stabilizing member to engage with the catheter and provide stabilization functionality.
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 device securely fixes catheters of varying diameters and types, maintains flow rate, and prevents kinking, enabling patient mobility and safety by reducing contamination risks.
Implementation Method 1
The deformable solid material may be deformed to engage with the catheter
Implementation Method 2
As the deformable solid material returns to its relaxed, un-compressed state, the deformable solid material may remain engaged with the catheter

AI summary
Device (100) for securing a catheter (700), comprising a base element (200) having a first side (201), and a second side (202) opposite the first side (201), and comprising a top element (500) having a first side (501) connectable with the second side (202) of the base element (200). When the first side (501) of the top element (500) is connected with the second side (202) of the base element (200), the top element (500) and the base element (200) are forming a feedthrough for the catheter (700) between the second side (202) of the base element (200) and the first side (501) of the top element (500). At least one of the base element (200) and the top element (500) comprises a deformable solid material (430) arranged such that the catheter (700) is locally tightly held between the base element (200) and the top element (500).
