Multi-Compartment Sub-Drawer Latching for Secure Medication Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Automated Dispensing Machines (ADMs) require multiple trips by nurses to manage and dispense medications, as they cannot store all medications and often lead to medication expiration due to infrequent use, and existing transport systems are inefficient for handling multiple medications securely.
Innovation Solution
A dockable multi-compartment sub-drawer with latching lids and a communication interface, allowing for secure storage and dispensing of multiple medications at the patient's bedside, enabling single-dose access and efficient transfer between ADMs, utilizing a processor to control lid release and sub-drawer engagement with a retention hook.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-compartment receptacle is used to securely transport medications, then security during transport is improved, but the ability to store multiple medications is worsened
Solution Approach 1:
The single-compartment receptacle is divided into multiple compartments, each capable of storing different medications. This segmentation allows the receptacle to securely transport multiple medications simultaneously while maintaining the security features of the original design, thus resolving the contradiction between security and versatility.
Solution Approach 2:
Multiple single-compartment receptacles are nested within a single drawer unit, allowing each receptacle to maintain its secure transport capabilities while the drawer provides additional organizational structure and capacity for multiple medications, effectively combining security with multi-medication storage.
2Productivity
If medications are stored in a typical ADM, then dispensing capability is improved, but medication expiration is worsened due to infrequent use
Solution Approach 1:
The system dynamically manages medication inventory by tracking expiration dates and prioritizing dispensing of medications that are接近 to expiration. The ADM interface provides real-time information about medication status, enabling dynamic adjustment of dispensing priorities to minimize waste while maintaining adequate stock for active prescriptions.
Solution Approach 2:
The system implements a first-expired-first-out (FEFO) inventory management approach, automatically identifying and prioritizing medications接近 to expiration for dispensing. When medications expire, the system tracks and reports them for proper disposal, ensuring minimal waste while maintaining efficient dispensing operations.
3Adaptability or versatility
If a pharmacist manually loads medications into an ADM, then medication availability is improved, but time consumption is worsened
Solution Approach 1:
Medications are pre-loaded into individual compartments of the receptacle before being placed in the ADM. This preliminary organization allows for rapid loading of the entire receptacle into the drawer without requiring manual placement of each individual medication, significantly reducing the time required while maintaining full medication availability.
Solution Approach 2:
Multiple medications are combined into a single integrated receptacle unit that can be loaded as one piece into the ADM drawer. This merging of multiple medications into a single loadable unit reduces the number of separate loading operations required, thereby reducing time consumption while ensuring all necessary medications are available.
4Productivity
If multiple trips are made between patient bedside and ADM, then medication dispensing is improved, but time efficiency is worsened
Solution Approach 1:
The receptacle acts as an intermediary container that can be loaded with multiple medications at the ADM and then transported to the patient bedside in a single trip. The receptacle maintains security and organization during transport, allowing the nurse to access multiple medications at the patient location without returning to the ADM, thus improving time efficiency while maintaining dispensing capability.

AI summary
A single-item-access (SIA) sub-drawer is disclosed that has a body with a compartment and a lid that is selectably se - curable in a closed position that encloses the compartment. The SLA sub-drawer includes a lid latch configured to secure and selectably release the lid and a sub-drawer latch configured to engage and selectably release a retention hook to secure the SIA sub-drawer to a dispensing cabinet. The SIA sub-drawer also includes a processor configured to cause the lid latch to release the lid upon receipt of a lid release signal and to cause the sub-drawer latch to release the retention hook upon receipt of a sub-drawer release signal.
