Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological parameter displaying apparatuses struggle to accurately plot and display data from two different sensors simultaneously, leading to difficulties in understanding circulatory dynamics due to non-temporally aligned measurements and readability issues with increasing data sets.
Innovation Solution
A biological parameter displaying apparatus that automatically plots data from two different sensors in XY coordinates, utilizing a CPU with a coordinate displaying unit, plot data producing unit, and plot displaying unit to show data in a time sequence manner, with features such as varying brightness, size, color, and shape to differentiate data points, and includes determination and region displaying units for normality and criticality assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data from two different sensors are plotted in XY coordinates to show circulatory dynamics, then the understanding of circulatory dynamics is improved, but the temporal alignment and simultaneous measurement of data becomes difficult to achieve
Solution Approach 1:
The system performs preliminary actions by continuously measuring and storing biological parameters from multiple sensors in advance, with time stamps, so that when plotting is required, the data is already prepared and aligned temporally. This eliminates the need for simultaneous manual measurements at the moment of plotting.
Solution Approach 2:
A computer acts as an intermediary that receives data from multiple independent sensors, synchronizes them based on time stamps, and performs the plotting operation. This intermediary handles the temporal alignment automatically, removing the need for manual coordination between measurements.
2Loss of information
If multiple data points are plotted to show time sequence, then the temporal relationship is clarified, but the readability of the display deteriorates
Solution Approach 1:
The time information is extracted from the coordinate data and displayed separately as a trend graph or time labels alongside the XY plot. This separates the temporal dimension from the spatial XY coordinates, allowing the main plot to remain clean and readable while time sequence information is preserved in a dedicated display area.
Solution Approach 2:
Time sequence information is displayed using additional visual dimensions such as color gradients, symbol sizes, or separate trend lines rather than cluttering the XY plot with excessive markers. This adds temporal context without compromising the readability of the primary coordinate display.
3Measurement precision
If manual measurement methods are used for cardiac index and pulmonary artery wedge pressure, then measurement accuracy is achieved, but the workability and efficiency deteriorate
Solution Approach 1:
Sensors continuously self-measure biological parameters and automatically transmit data to the computer system. The system performs automatic plotting and analysis without requiring medical personnel to manually conduct measurements, thereby maintaining measurement accuracy through continuous monitoring while dramatically improving efficiency.
Solution Approach 2:
Manual mechanical measurement operations are replaced with electronic sensors and automated computer processing. This substitution maintains or improves measurement precision through continuous electronic monitoring while eliminating the time-consuming nature of manual procedures.

AI summary
A biological parameter displaying apparatus includes: a coordinate displaying unit which displays first coordinates in which a first biological parameter of a patient, which is measured by a first measuring unit, is set as an X-axis, and a second biological parameter of the patient, which is different in kind from the first biological parameter and which is measured by a second measuring unit, is set as a Y-axis; a plot data producing unit which produces first plot data, each of the first plot data being produced based on first measurement values of the first and second biological parameters which are measured at a same time or in a same time zone; and a plot displaying unit which plots the first plot data in the first coordinates.
