Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physiological information collecting devices lack flexibility in remote observation of physiological data, requiring specific equipment and protocols for immediate data transmission and visualization.
Innovation Solution
A physiological information collecting device with a processor that selectively uses either a first communication protocol for responding to requests or a second protocol for continuous data transmission, allowing immediate display of data on a terminal device, and a terminal device that adjusts visualization based on screen size and data amount, reducing dependency on the collecting device's specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a web server function is installed in the electrocardiograph to transmit data files, then remote observation of electrocardiogram waveforms is enabled, but the device complexity increases and requires specific equipment setup
Solution Approach 1:
The patent applies universality by enabling the physiological information collecting device to serve multiple functions: it acts as both a data collection device and a web server that can be accessed by any terminal device with a web browser. This eliminates the need for specialized remote viewing equipment while maintaining remote observation capability, thus reducing device complexity while improving adaptability.
Solution Approach 2:
The patent uses copying by transmitting physiological information data in a standardized format that can be displayed on any terminal device with a web browser. Instead of requiring dedicated viewing equipment, the system creates a universal interface through web protocols that copies the functionality across different devices, reducing the need for specialized hardware.
2Loss of time
If data transmission is performed only in response to requests, then the communication protocol is simple, but the immediacy of data observation is reduced
Solution Approach 1:
The patent applies dynamics by implementing a communication system that can adapt between two modes: request-response mode for simplicity and push transmission mode for immediacy. The system dynamically switches based on the clinical needs, allowing immediate data transmission when required while maintaining protocol simplicity through selective execution, thus reducing time loss without excessive complexity.
Solution Approach 2:
The patent uses periodic action by enabling automatic data transmission at predetermined intervals or when specific conditions are met. This periodic push transmission ensures that physiological information is transmitted immediately when new data is acquired, eliminating delays associated with manual requests while maintaining manageable protocol complexity through time-based triggers.
3Adaptability or versatility
If the terminal device displays physiological information based on fixed aspect ratio, then the visualization is consistent, but the adaptability to different screen sizes is reduced
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the display aspect ratio and visualization parameters based on the terminal device's screen characteristics. The system modifies display parameters such as width, height, and scaling factors to adapt to different screen sizes while maintaining the essential characteristics and consistency of the physiological information presentation, thus improving adaptability without sacrificing visualization precision.
Data Source
AI summary
A reception interface is configured to receive physiological information of a subject. A communication interface is configured to allow communication with a terminal device provided with a display. A processor is configured to create data for visualize information including at least the physiological information. The processor is configured to selectively execute either one of: a first communication protocol configured to transmit the data from the communication interface as a reply to a request transmitted from the terminal device; and a second communication protocol configured to transmit the data from the communication interface at a prescribed timing while maintaining connection established by a request transmitted from the terminal device. Information corresponding to the data transmitted by the second communication protocol has a higher priority for requiring an immediate display on the display than the information corresponding to the data transmitted by the first communication protocol.
