Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accidental needle sticks remain a significant issue in healthcare settings despite regulations, with many medical procedures requiring needles, such as subcutaneous insulin injections, lacking effective solutions for safe tissue gripping and needle handling.
Innovation Solution
A hand-operated device with a cylindrical body, flange, and skin-contacting elements, including spring and gripping components, designed to guide a syringe and assist in gripping tissue for safe subcutaneous injections, preventing unwanted needle sticks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle is used for subcutaneous injection administration, then the injection can be delivered effectively, but accidental needle sticks occur frequently causing safety hazards
Solution Approach 1:
The device introduces an intermediary guide structure that mediates between the needle and the patient's tissue. The guide element positions and stabilizes the needle during insertion, allowing the needle to be controlled more precisely while reducing the risk of accidental sticks to healthcare workers during the injection process
2Ease of operation
If manual tissue gripping is performed during subcutaneous injection, then tissue engagement is achieved, but inconsistent gripping leads to injection inaccuracies
Solution Approach 1:
The device enables self-service tissue gripping through its guide structure that automatically engages with and positions the tissue. The guide element is designed to naturally grasp and stabilize the tissue during insertion, eliminating the need for manual gripping techniques and ensuring consistent, accurate tissue engagement without requiring skilled manual manipulation
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 effectively prevents needle sticks and aids in safe tissue gripping, enhancing the safety and efficacy of subcutaneous injections by providing a controlled mechanism for needle insertion and tissue engagement.
Implementation Method 1
a spring element disposed at a proximal end and configured to couple with the cylindrical body
