Digital Pen Captures Handwritten Patient Symptoms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ambulatory patient monitoring systems face challenges in recording and integrating patient symptoms with physiological data, as patients often fail to comply with symptom diaries, and existing devices lack specificity in capturing handwritten medical data.
Innovation Solution
A medical monitoring system incorporating a digital pen that captures handwritten data and aggregates it with physiological data from an implantable medical device, allowing for bidirectional communication and transmission to a central database for unified presentation to clinicians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a patient activator with buttons is used to transmit signals, then the device can transmit basic symptom information, but the specificity of information transferred to the monitoring device is limited
Solution Approach 1:
The patent uses a digital pen to capture handwritten notes and creates a digital copy of the patient's symptom descriptions. This digital copy is then transmitted to the monitoring device, preserving the full specificity of the patient's written observations without requiring complex input interfaces on the monitoring device itself.
Solution Approach 2:
The digital pen serves as an intermediary device between the patient and the monitoring device. Instead of requiring the monitoring device to have complex input capabilities, the digital pen captures detailed handwritten information and transmits it digitally, acting as a mediator that bridges the simplicity of the monitoring device with the need for detailed symptom capture.
2Loss of information
If patients are asked to keep a symptom diary, then physiological data can be correlated with patient symptoms, but patient compliance is not always full
Solution Approach 1:
The digital pen automatically captures handwritten notes as digital data, eliminating the need for patients to manually transcribe or recall symptoms later. This automatic digital copying process occurs at the moment of symptom occurrence, ensuring both compliance and accurate correlation with physiological data.
Solution Approach 2:
The system performs preliminary capture of symptom information at the moment it occurs through the digital pen. By capturing data immediately when symptoms are experienced rather than requiring later recall or transcription, the system ensures high compliance rates and accurate temporal correlation with physiological measurements.
3Loss of information
If manual symptom recording is required, then symptom information can be captured, but the task of correlating written records with physiological data is burdensome
Solution Approach 1:
The digital pen creates immediate digital copies of handwritten symptom records, which are automatically time-stamped and can be directly correlated with physiological data. This eliminates the manual process of transcribing paper diaries into digital formats and reduces the time required for data correlation by providing machine-readable data from the outset.
Solution Approach 2:
The system replaces the mechanical process of manual diary keeping and paper-based correlation with an electronic digital capture and automated data association system. The digital pen and monitoring device communicate electronically, automatically correlating symptom data with physiological measurements without requiring manual intervention for data matching.
Data Source
AI summary
A medical device system and method for monitoring a patient include a monitoring device for storing data relating to the patient and a digital pen for digitizing and storing data handwritten by the patient. A control module is configured to aggregate data stored by the monitoring device and handwritten data stored by the digital pen.
