Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing individualized compound doses of medicines face challenges such as rejected packages due to incorrect dosing and stock shortages, leading to inefficiencies and manual rechecking processes.
Innovation Solution
A method and device for receiving and checking individualized compound doses, involving automated analysis and indexing of doses, where only correctly composed doses are packaged, and incorrectly composed doses are buffered for later packaging, allowing continuous operation and minimizing rejections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If automated checking is performed on each dose before packaging, then manufacturing precision is improved, but productivity deteriorates due to line halting
Solution Approach 1:
The system performs checking actions in advance by creating a virtual model of the dose composition before actual packaging occurs. The virtual dose compartment receives virtual medicines representing the actual dispensed medicines, allowing the checking process to complete ahead of time so that the physical packaging line does not need to halt for verification.
Solution Approach 2:
The invention creates a virtual copy of the dose compartment and virtual copies of the medicines to represent the physical objects. This virtual model allows automated checking to occur on the digital representation without interrupting the physical packaging process, thereby maintaining both precision and productivity.
2Manufacturing precision
If incorrect doses are rejected from the packaging line, then manufacturing precision is maintained, but loss of time increases due to manual rechecking
Solution Approach 1:
The system provides immediate automated feedback when a dose composition is incorrect. The virtual checking process identifies errors and triggers automatic corrective actions, eliminating the need for manual rechecking and reducing time loss while maintaining precision through continuous monitoring and correction.
Solution Approach 2:
The system performs self-verification and self-correction of dose compositions. When an error is detected in the virtual model, the system automatically identifies and corrects the issue without requiring human intervention, thereby maintaining manufacturing precision while minimizing time loss.
3Manufacturing precision
If the packaging line halts to verify dose composition, then manufacturing precision is ensured, but productivity decreases due to continuous stopping
Solution Approach 1:
The verification process is performed in advance using virtual models before the physical packaging line needs to halt. By completing the checking process on the virtual representation beforehand, the system ensures precision verification occurs without interrupting the continuity of the actual packaging operation.
Solution Approach 2:
The invention uses a virtual copy of the packaging line and dose compartments to perform verification operations. This digital twin allows complete dose composition verification to occur in parallel with the physical packaging process, ensuring precision without compromising line continuity or productivity.

AI summary
A method of receiving and checking individualized compound doses of medicines is disclosed. The method includes a repetition of the steps of - receiving a plurality of dispensed medicines that form an individualized compound dose of medicines, - assessing the composition of the individualized compound dose of medicines trough automated recognition of the received medicines, - checking the assessed composition of the received individualized compound dose of medicines against a record for the composition of that individualized compound dose of medicines, and - if the outcome of the check is positive, discharging the received individualized compound dose of medicines to be packaged in a dose compartment of a multi dose compartment package, and - if the outcome of the check is negative, discharging the received individualized compound dose of medicines other than to be packaged in a dose compartment of the multi dose compartment package. The disclosure also includes a device for receiving and checking individualized compound doses of medicines.
