PCA Pump Volume Tracking Across Multiple Syringes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of accurately tracking medication delivery using patient-controlled analgesia pumps, particularly in scenarios where multiple syringes are used, leads to potential medication abuse or diversion due to the difficulty in monitoring the actual volume of medication administered to patients.
Innovation Solution
A tracking engine is integrated with the patient-controlled analgesia pump to monitor the volume of medication delivered across multiple syringes and doses, utilizing identifier tags and volume meters to track and update counters, and generate alerts for anomalies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patient-controlled analgesia pumps are used to allow patient self-administration of medication, then patient control and convenience are improved, but the risk of medication abuse or diversion increases
Solution Approach 1:
The system continuously monitors medication delivery volume and provides feedback through electronic alerts to medical professionals when anomalies are detected. The tracking engine compares actual delivery against expected patterns and triggers alerts for unusual consumption patterns, enabling real-time oversight of patient self-administration.
Solution Approach 2:
An intermediary tracking system is introduced between the patient-controlled pump and the medication reservoir. This tracking engine acts as a mediator that monitors all medication deliveries, records volume data, and communicates with medical professionals, providing an intermediate layer of control that maintains patient autonomy while preventing abuse.
2Duration of action of stationary object
If multiple syringes are used to extend medication supply, then medication availability is improved, but tracking accuracy deteriorates
Solution Approach 1:
The system segments the tracking process into discrete components: individual syringe identification using identifier tags, volume measurement using volume meters for each syringe, and cumulative tracking across multiple syringes. Each syringe is tracked separately with its own identifier tag, and the system maintains separate records for each syringe while providing aggregate tracking.
Solution Approach 2:
Syringes are pre-tagged with unique identifier tags before insertion into the pump. The tracking system is pre-configured to recognize these tags and initiate tracking protocols. When a syringe is inserted, the system immediately reads the identifier tag and sets up tracking parameters, ensuring accurate tracking from the moment the syringe begins delivering medication.
3Reliability
If continuous monitoring of medication volume is implemented, then medication safety is improved, but system complexity increases
Solution Approach 1:
The pump system performs self-monitoring of medication delivery volume using integrated volume meters. The tracking engine automatically records delivery data without requiring external intervention. The system self-identifies syringes through reader devices that automatically scan identifier tags, and automatically generates alerts when anomalies are detected, reducing the need for manual monitoring.
Solution Approach 2:
The tracking engine serves multiple functions: it identifies syringes using identifier tags, measures delivery volume using volume meters, accumulates delivery data across multiple syringes, detects anomalies through comparison with expected patterns, and generates electronic alerts. This multi-functional approach consolidates what could be multiple separate systems into a single integrated tracking solution.
Data Source
AI summary
A method may include receiving, from a volume meter at a pump configured to deliver medication to a patient, data indicative of a volume of a medication present in a syringe inserted in the pump. A first counter may be updated, based on the data, in response to the medication being delivered to the patient as a first dose type. A second counter may be updated, based on the data, in response to the medication being delivered to the patient as a second dose type. The volume of the medication delivered to the patient may be determined based on the first counter and/or the second counter. An electronic alert may be sent to a mobile device in response to one or more anomalies being present in the volume of the medication delivered to the patient. Related methods and articles of manufacture, including apparatuses and computer program products, are also disclosed.
