Double-Action Depilling Mechanism for Blister Medication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medication dispensing systems for controlled drugs in hospitals face challenges such as contamination, inefficiency, and risk of overdose due to manual handling and lack of regulated dispensing mechanisms, especially when using conventional blister packs.
Innovation Solution
A double-action depilling mechanism for blister packs that includes a first pusher to engage and partially release a dosage form, followed by a second pusher to completely expel it from the blister, ensuring controlled and sequential delivery of medication while maintaining the drug in its original packaging until administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of blister packs is used to dispense medication, then the dispensing process is simple and flexible, but contamination risk increases and medication integrity deteriorates
Solution Approach 1:
The invention extracts the medication from the blister pack through a controlled mechanical depilling mechanism that removes only the necessary dosage while leaving the remaining medication sealed in the original packaging, thus preventing contamination while automating the dispensing process
Solution Approach 2:
The device introduces an intermediary mechanism (the depilling apparatus with pushers and recesses) that mediates between the blister pack and the medication, allowing controlled extraction without direct human contact with the exposed medication, thereby reducing contamination risk
2Adaptability or versatility
If controlled drugs are stored in blister packs and manually accessed, then flexibility in administration is maintained, but dispensing efficiency decreases and time consumption increases
Solution Approach 1:
The device enables self-service dispensing where the controlled mechanism automatically extracts and delivers the medication dosage without requiring nurse intervention for the actual extraction, improving efficiency while maintaining controlled access protocols
Solution Approach 2:
The invention replaces the manual mechanical action of nurses handling blister packs with an automated mechanical depilling system that can precisely and quickly extract medication, thereby increasing dispensing efficiency while maintaining the flexibility of controlled administration
3Reliability
If nurses manually administer each pill to patients, then controlled drug accountability is maintained, but time consumption increases and productivity decreases
Solution Approach 1:
The device incorporates feedback mechanisms (such as indicators showing whether a blister has been depilled) that provide immediate information about the dispensing status, enabling automated tracking and accountability of controlled drugs without requiring time-consuming manual verification by nurses
4Device complexity
If a single pusher mechanism is used to extract medication from blisters, then device complexity is reduced, but extraction reliability is insufficient for stubborn dosages
Solution Approach 1:
The depilling mechanism is segmented into multiple functional components (first pusher, second pusher, recesses) that work in sequence, where the first pusher applies initial force and the second pusher completes the extraction, ensuring reliable removal of even stubborn dosages while keeping each individual component relatively simple

AI summary
The present invention provides a depilling device for a blister package comprising at least one array of dosage forms to be dispensed, wherein each dosage form is contained within a blister formed as a covered cavity bounded by a backing, said device comprising a double action depilling mechanism, comprising a first pusher, sized and adapted to engage a top surface of said covered cavity and to exert a first sufficient force thereagainst so as to push said dosage form contained therein against its respective bounding backing, and a second pusher sized and adapted to more forcibly engage said top surface of said covered cavity and to exert a second sufficient force thereagainst so as to expel said dosage form from said blister.
