Blister Card Preparation Fixture for Multi-Dose Medication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of filling and sealing multi-dose blister cards is tedious, time-consuming, and costly due to the need for manual handling by pharmacists or technicians, as each patient requires a unique prescription medication combination, making it inefficient compared to single-dose blister cards.
Innovation Solution
A method and apparatus using a fixture to align, fill, and seal blister cards with medicaments according to a predetermined prescription, involving a support plate with pins for alignment, a backing layer for sealing, and data storage for verification, allowing for automated or semi-automated processing to ensure accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual filling and sealing process is used for multi-dose blister cards, then each patient can receive customized prescription combinations, but the process becomes tedious, time-consuming, and costly
Solution Approach 1:
The patent divides the blister card into multiple individual blisters arranged in a grid pattern, with each blister capable of containing different medicaments. This segmentation allows independent filling of each blister while maintaining an organized structure that can be efficiently processed through automated or semi-automated means, resolving the contradiction between customization capability and processing speed.
Solution Approach 2:
The patent creates a universal blister card format that can accommodate various prescription combinations through standardized multi-dose blisters. Each blister card follows a consistent structure with multiple blisters that can be filled with different medications according to specific patient needs, enabling the system to handle diverse prescriptions efficiently without requiring entirely different processes for each case.
2Manufacturing precision
If manual verification of prescription contents is performed, then accuracy can be ensured, but the process becomes time-consuming and costly
Solution Approach 1:
The patent incorporates a verification process where the filled blister card contents are checked against the patient's prescription requirements. This feedback mechanism ensures accuracy by comparing the actual medicaments placed in each blister with the prescribed combination, allowing for error detection and correction while maintaining an efficient workflow that doesn't require excessive verification time.
Solution Approach 2:
The patent organizes the blister card structure and prescription information in advance, preparing the framework before the actual filling process. By having the blister card layout, prescription details, and filling sequence predetermined, the verification process becomes more streamlined and efficient, reducing the time required while maintaining accuracy through pre-planned organization.

AI summary
A method of preparing a blister card to contain medicaments in accordance with a predetermined prescription, comprises positioning a blister sheet blank having a plurality of blisters onto a support surface of a fixture. Each of the blisters are then at least partially filled with one or more medicaments in accordance with the predetermined prescription. Then, a backing layer blank is positioned over the blister sheet blank to retain the medicaments in the blisters and to prevent contamination. Finally, the blister sheet blank and the backing layer blank are sealed together while positioned on the fixture to form a sealed blister card.
