Solution Overview

Problem

Medication errors in hospitals, nursing homes, and home environments result in significant harm due to improper medication administration, including incorrect medications, dosages, and timing, often caused by manual processes prone to human error.

Innovation Solution

A medication verification and dispensing apparatus that uses imaging and identification technologies to confirm the correct medication, dosage, and timing, and a locking mechanism that only releases the medication to the correct patient, ensuring accurate administration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual medication administration is used, then ease of operation is maintained, but medication error rate increases

Engineering Contradiction:
Improvemedication administration accuracyVSAvoidverification system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection and memory-based verification with an automated imaging system. Cameras capture images of medication pills, and image recognition algorithms automatically identify and verify medication characteristics, eliminating human error in the verification process while maintaining operational simplicity for the end user.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates digital copies (images) of the physical medication pills and stores them in a database for comparison. When verification is needed, the system retrieves stored images of correct medications and compares them with images of the actual pills, providing reliable verification without requiring complex physical measurement or analysis systems.

Inventive Principle:
Principle #26Copying

2Measurement precision

If imaging technology is used to verify medication identity, then medication verification accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvemedication identification accuracyVSAvoidimaging and verification system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system creates digital copies (images) of the physical medication pills and stores them in a database for comparison. When verification is needed, the system retrieves stored images of correct medications and compares them with images of the actual pills, providing reliable verification without requiring complex physical measurement or analysis systems.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary database of reference images that mediates between the camera and the verification decision. Instead of requiring complex real-time analysis, the system compares captured images against pre-stored reference images, simplifying the verification logic while maintaining high accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If locking mechanism is used to control medication dispensing, then patient safety is improved, but ease of operation decreases

Engineering Contradiction:
Improvepatient medication safetyVSAvoidmedication dispensing convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism receives feedback from the image verification system and automatically adjusts its state. When verification confirms the medication is correct, the lock automatically unlocks, allowing the patient to retrieve their medication. This automated feedback loop maintains safety while eliminating manual locking/unlocking operations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service verification and dispensing control. The imaging system automatically verifies medication identity, the system automatically compares images against patient records, and the locking mechanism automatically releases medication to the correct patient without requiring manual intervention, thereby maintaining convenience while enhancing safety.

Inventive Principle:
Principle #25Self-service

AI summary

Medication errors happen frequently in hospital, home, and pharmacy environments. A medication verification and dispensing system provides protection against such errors. The apparatus includes a guide tube that receives a medication and imaging device(s) adjacent to the guide tube that take image(s) of the medication. The imaging devices(s) and light source(s) are oriented for capturing images that reveal markings, color, size, shape, etc., of the medication. A verification system uses a signature of the image to identify the medication or compares the image(s) to reference images to identify the medication and to a prescription record of the patient to ensure it is a correct medication, dose, amount, timing, etc., for administration. If the medication is correct, it is dispensed into a dispensing vessel that locks the medication inside, but unlocks when it recognizes a unique patient identifier worn by a patient that is a correct recipient for the medication.
