Segmented Drug Kit for Safe Dose Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for administering anti-cancer agents through intravenous drip infusion pose a risk of exposure to medical practitioners due to the cytotoxic nature of these agents, and existing closed systems are complex, costly, and not fully effective in preventing exposure, with a need for dose adjustment capabilities that are not supported by existing double bag products.
Innovation Solution
A kit product comprising a bag with a drug-enclosing portion and a sealing mechanism that allows for dose adjustment by connecting and disconnecting drug-enclosing portions, enabling precise dosing while preventing exposure, and includes features such as re-sealable compartments and adjustable drug amounts to accommodate varying patient needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If closed system transfer devices are used to prevent exposure to anti-cancer agents, then exposure levels are decreased, but operation complexity increases and labor efficiency decreases
Solution Approach 1:
The drug container is divided into multiple separable compartments, each containing a specific dose of the anti-cancer agent. This segmentation allows the system to maintain safety while simplifying operation, as only the required compartment needs to be accessed rather than managing a complex closed system.
Solution Approach 2:
The invention extracts the essential function of dose adjustment from the complex closed system transfer devices and implements it through a simplified compartment-based container. This removes unnecessary complexity while preserving the core safety and dosing capabilities.
2Object-affected harmful factors
If closed systems are used to prevent exposure to anti-cancer agents, then exposure levels are decreased, but cost increases
Solution Approach 1:
The invention employs disposable, single-use compartments that can be easily discarded after use, eliminating the need for expensive, complex closed system transfer devices. These simple, low-cost compartments provide sufficient protection and can be replaced rather than requiring costly infrastructure.
3Ease of operation
If double bag type products are used to simplify filling operation, then ease of operation is improved, but dose adjustment capability is lost
Solution Approach 1:
The container is segmented into multiple compartments, each representing a different dose level. This segmentation maintains the simplicity of the double bag design while adding dose adjustment capability through the selection and combination of different compartments.
Solution Approach 2:
The system allows dynamic dose adjustment by enabling the user to select and combine different compartments based on the patient's specific requirements. This dynamic flexibility is achieved without complicating the overall operation, as each compartment remains independently accessible and manageable.

AI summary
A kit preparation that enables drug dose adjustment. The kit preparation includes a bag which contains an infusion solution or pure water and at least one drug enclosing part in which a drug is enclosed and which is provided with a sealing part. The drug enclosing part is connected to the bag via the sealing part; and, when the sealing part is released, the bag is communicated with the drug enclosing part and thus the drug is poured into the bag so that a dispensing work can be carried out.
