Needle Bandage with Segmented Adhesive and Viewing Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing needle insertion methods for intravenous or subcutaneous procedures face challenges in securely attaching the needle to the patient's skin, preventing movement and ensuring proper clotting after removal, while also ensuring safety and ease of use.
Innovation Solution
A flexible bandage system with multiple regions, including adhesive and non-adhesive areas, is used to securely attach a butterfly needle to the patient's skin, featuring a hemostasis pad for clotting promotion and a viewing window for monitoring, allowing for easy needle removal and secure attachment to prevent movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a bandage is used to secure the needle to the patient's skin, then the needle stability is improved, but the needle removal process becomes more complex
Solution Approach 1:
The bandage is divided into multiple functional regions: a first region with adhesive for skin attachment, a second region with a hole for needle passage, and a third region with additional adhesive for securing the needle hub. This segmentation allows the bandage to provide stable fixation while enabling controlled needle removal by detaching specific regions.
Solution Approach 2:
The bandage is pre-configured with strategically placed adhesive regions and a central hole before application. The first adhesive region is positioned to attach to the skin, the hole is pre-formed for needle insertion, and the second adhesive region is positioned to secure the needle hub. This preliminary configuration simplifies the securing process while maintaining ease of removal.
2Reliability
If a secure attachment method is used to prevent needle movement, then the reliability of the procedure is improved, but the device complexity increases
Solution Approach 1:
The single bandage structure performs multiple functions: it secures the needle to the skin, provides a stable base for the needle hub, allows for needle insertion and removal, and maintains proper positioning throughout the procedure. This multi-functionality reduces the need for multiple separate components while ensuring procedure reliability.
Solution Approach 2:
Different regions of the bandage have different properties optimized for their specific functions: the first region has adhesive for skin attachment, the central area has a hole for needle passage, and the second region has adhesive for hub securing. This local differentiation of properties allows each part to contribute to overall reliability without requiring complex integration throughout the entire bandage.
3Object-affected harmful factors
If the bandage covers the entire access site, then the protection and clotting promotion is improved, but the visibility of the access site deteriorates
Solution Approach 1:
The bandage is designed with a central hole in the second region that aligns with the needle insertion site, creating a localized transparent or open area for visibility. The surrounding adhesive regions provide protection and clotting promotion while the central opening maintains visibility of the access site, allowing monitoring without compromising protection.
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 bandage system effectively secures the needle in place, facilitates easy removal without movement, promotes clotting, and provides a clear view of the access site, enhancing safety and usability during medical procedures.
Implementation Method 1
The adhesive portion of the bandage can be adhered to the skin of the patient
Implementation Method 2
The bandage can include a hemostasis pad over the access site to encourage clotting after needle removal

AI summary
A bandage can be used to secure a needle to an access site so as to prevent unintended movement or withdrawal of the needle from the access site during administration of a treatment to a patient. After treatment, the needle can be removed by manipulating a portion of the bandage. Another portion of the bandage can be maintained in position over the access site during needle removal and can be used to promote clotting of the site after needle removal. The bandage may include a clotting agent, a hemostasis pad, and/or a clot-promoting structure. Additionally or alternatively, finger pressure can be applied to the access site through the bandage. For example, the bandage may include a viewing window without any adhesive to allow visual monitoring of the access site during treatment. Finger pressure may be applied to the viewing window and thereby to the access site during and after needle removal to encourage hemostasis.
