Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for preparing and administering antiblastic chemotherapy drugs face issues with accidental spreading and contamination due to manual blocking mechanisms, leading to waste and increased risk for healthcare professionals.
Innovation Solution
A device with a secure anti-spreading mechanism using removable breaking security means and a Y-shaped joining element with self-sealing regulators, preventing accidental flow until manually activated by healthcare staff, combined with light-filtering materials to protect sensitive drugs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manually removable blocking means are used to control liquid flow, then the device is easy to operate and can be manually controlled, but the risk of accidental spreading increases due to shocks or sudden maneuvers
Solution Approach 1:
The security means are pre-installed in the device to provide preliminary protection against accidental spreading. The breakable security means are positioned to automatically block the passage channel before any accidental shock can cause leakage, and only need to be manually removed when intentional administration is required.
Solution Approach 2:
The breakable security means act as a preliminary protective barrier that absorbs or prevents the harmful effect of accidental shocks. The frangible design allows the security means to break cleanly under controlled conditions while maintaining blocking function under accidental stress, cushioning against unintended drug release.
2Ease of operation
If manually removable blocking means are used, then the device can be flexibly controlled, but the waste of antiblastic chemotherapy drugs increases due to accidental spread
Solution Approach 1:
The breakable security means provide preliminary protection that prevents accidental spreading before it can occur. By having the security means already in place and functional, the system prevents the harmful event (accidental spread leading to waste) rather than responding after waste has occurred.
3Ease of operation
If manually removable blocking means are used, then the device can be operated manually, but the contamination risk to healthcare professionals increases
Solution Approach 1:
The security means are pre-installed to provide preliminary protection against contamination. By blocking the passage channel before any accidental shock, the security means prevent the harmful substance from reaching healthcare professionals, addressing the contamination risk before it can materialize.
4Stability of the object's composition
If light-filtering materials are used to protect sensitive drugs, then the drug stability is improved, but the device complexity increases
Solution Approach 1:
The light-filtering function is merged with the existing passage channel structure. The passage channel is constructed from material that inherently provides both the flow pathway and light filtration, combining two functions into a single integrated component rather than adding separate light-filtering elements.
Solution Approach 2:
The material properties of the passage channel are changed to provide light-filtering capability. By selecting material with specific optical properties (light-filtering characteristics), the passage channel simultaneously performs its primary function of fluid transport and the secondary function of protecting the drug from light degradation.
