Medical Container Abnormal State Detection via Weight and Inclination Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices fail to notify medical personnel of abnormal states in medical containers, such as a patient's discomfort indicated by the medical container being pulled obliquely or falling, which are not addressed by existing weight and flow monitoring systems.
Innovation Solution
A device and method that integrate a weight detecting unit, an inclination detecting unit, and a controlling unit to monitor weight and inclination changes in medical containers, comparing these data with presets to trigger a warning unit, which can transmit alerts wirelessly, ensuring immediate notification of medical personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical personnel manually monitor and replace medical containers based on dose or flow speed, then they can ensure proper medicament delivery, but it disturbs the patient and is troublesome for medical personnel
Solution Approach 1:
The medical container system performs self-monitoring of its own state (weight, inclination, flow speed) through integrated sensors and processing units, automatically detecting when replacement is needed without requiring manual inspection by medical personnel, thus eliminating patient disturbance while maintaining reliable medicament delivery
Solution Approach 2:
The system continuously monitors weight changes and inclination angles of the medical container, comparing actual values against preset thresholds and providing real-time feedback to both local alarms and remote monitoring platforms, enabling timely automatic replacement decisions without manual intervention
2Measurement precision
If conventional weight sensors monitor flow speed changes in drip bottles, then they can detect abnormal flow speeds, but they cannot notify medical personnel when the patient turns or trembles causing container inclination
Solution Approach 1:
The system combines weight detection, inclination detection, and flow speed calculation into a single integrated monitoring device that simultaneously measures multiple parameters (weight via weight sensor, inclination via inclination sensor, flow speed via processing unit), enabling comprehensive detection of both flow abnormalities and patient movement-induced container position changes
Solution Approach 2:
The monitoring device performs multiple functions: it monitors medicament flow speed through weight changes, detects patient movement through inclination angle changes, provides local alarm notifications, and transmits data to remote monitoring platforms, making it a universal solution for both flow monitoring and patient status detection
3Reliability
If medical containers are replaced frequently to ensure proper function, then medicament delivery reliability is maintained, but medical personnel time and efficiency are reduced
Solution Approach 1:
The system continuously monitors weight and inclination parameters and compares them against preset thresholds in advance, detecting when a medical container is approaching the need for replacement before it actually fails, allowing medical personnel to plan replacements during convenient times rather than responding to urgent situations, thus maintaining reliability while improving efficiency

AI summary
A method for detecting abnormal state of medical container contains steps of: enabling a weight detecting unit to detect weight of a medical container which is coupled with a patient to acquire content change data; enabling an inclination detecting unit to detect inclination state of the medical container to acquire inclination data; receiving the content change data and the inclination data by a controlling unit; and comparing the content change data and the inclination data with preset content data and initial inclination data respectively, such that when the content change data is different from the preset content data, a warning unit is started by the controlling unit; or when the inclination data is different from the initial inclination data, the warning unit is started by the controlling unit. In addition, a device for detecting abnormal state of the medical container matches is used to execute above-mentioned steps.
