Timed Infusion and Blood Sampling Control for Accurate Event Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion therapy is prone to human errors in recording infusion and blood sample times, leading to difficulties in monitoring patient health and treatment efficacy, as doctors or nurses may inaccurately record times, neglect samples, or perform infusions incorrectly.
Innovation Solution
An automated blood sampling and infusion system with a controller that manages infusion and sampling events, timestamping them, and storing data in a memory unit, using a multi-lumen catheter for simultaneous infusion and sampling, and integrating with a user interface and additional electronic devices for precise control and data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual recording of infusion and blood sample times is performed by doctors or nurses, then the process is simple and requires minimal equipment, but human errors occur leading to inaccurate time recording and compromised data reliability
Solution Approach 1:
The system performs automatic time recording and sample collection without requiring manual intervention. The controller automatically timestamps infusion events and blood sample events, eliminating human error in time recording while maintaining system simplicity through automation of routine tasks
Solution Approach 2:
The patent replaces manual mechanical recording processes with an automated electronic control system that uses sensors and processors to automatically record timestamps and control sample collection, thereby improving data accuracy without significantly increasing overall system complexity
2Measurement precision
If automated blood sampling and infusion systems are implemented, then time recording accuracy is improved and human error is reduced, but the device complexity and cost increase
Solution Approach 1:
The patent combines the infusion pump, blood sampling pump, and control system into an integrated automated platform. The controller merges multiple functions (infusion control, blood sampling control, timestamp recording, and data storage) into a single coordinated system, improving measurement precision while managing complexity through functional integration
Solution Approach 2:
The controller serves multiple functions simultaneously: it controls the infusion pump, controls the blood sampling pump, automatically timestamps events, stores data in memory, and coordinates between different components. This multi-functionality improves time recording precision without requiring separate dedicated systems for each function

AI summary
Automated blood sampling and infusion systems are disclosed, which include a sampling pump in communication with a blood sample collection apparatus; an infusion pump configured to perform infusion; and a controller. The controller is configured to: control the infusion pump to perform the infusion on a patient during an infusion event, control the sampling pump to draw blood from the patient into the blood sample collection apparatus during a sample collection event following the infusion event, and automatically store in a memory unit a timestamped data of the infusion event and the sample collection event. There may be multiple infusion events and sample collection events.
