Sequential Blister Package for Medication Adherence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pharmaceutical packaging systems fail to provide a convenient, simple, and effective means for selective access and administration of complex sequential therapeutic regimens, particularly for simultaneous prescription and non-prescription substances, leading to poor patient compliance and safety issues due to incorrect sequential dosing.
Innovation Solution
A disposable blister package system featuring a carrier sheet with depressions covered by overlapping cover sheets, where access to each depression is sequentially unlocked by removing preceding cover sheets, ensuring medications are taken in the correct order through a predetermined sequence, facilitated by grip-enhancing elements and color coding for time indicia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple medications are placed in a single blister package for complex sequential therapeutic regimens, then patient compliance and safety are improved through predetermined opening sequence, but device complexity increases due to multiple overlapping cover sheets and grip-enhancing elements
Solution Approach 1:
The blister package is segmented into multiple sealed compartments, each containing a specific medication dose. Each compartment has its own cover sheet that must be removed in a predetermined sequence, physically dividing the medication administration process into discrete, ordered steps that guide patient compliance.
Solution Approach 2:
The package structure is pre-configured with overlapping cover sheets and grip-enhancing elements arranged in a specific sequence before use. This preliminary arrangement of components ensures that patients can only access medications in the correct order, with each cover sheet's position and attachment predetermined to enforce the administration sequence.
2Reliability
If sequential access to medications is enforced through overlapping cover sheets, then incorrect dosing is reduced, but ease of operation deteriorates due to multiple removal steps
Solution Approach 1:
The package structure itself provides the instructional guidance for sequential administration through its physical design. The overlapping cover sheets and grip-enhancing elements create a self-explanatory system where the structure dictates the correct opening sequence without requiring external instructions, making the dosing accuracy enforcement self-service rather than instruction-dependent.
3Adaptability or versatility
If storage-incompatible substances are placed together in separate compartments, then simultaneous administration is enabled, but manufacturing precision requirements increase for sealing and compartment formation
Solution Approach 1:
Multiple sealed compartments are nested within the single blister package structure, with each compartment independently sealed to maintain storage incompatibility between substances. The compartments are arranged and sealed in a nested configuration that allows simultaneous storage of multiple medications while maintaining their individual integrity until administration time.

AI summary
The invention relates to a system for opening a medical blister package which is easy and convenient to open for people of all level of ability and dexterity. Its design allows for selective access to the blisters by following a predetermined opening sequence, therefore minimizing involuntary wrong up taking of medicine due to patient errors as wrong sequential opening is not achievable by involuntary mistakes.
