Rotating Display Fingertip Oximeter for Occlusion-Free Pulse Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fingertip oximeters require users to bend their fingers to read measurement results, leading to partial occlusion of arterial blood capillaries, which weakens the pulse signal and reduces measurement precision.
Innovation Solution
A fingertip oximeter with multiple display modes that can be easily switched, allowing users to view results from any direction without bending their fingers, combined with voice reporting for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user bends their finger to read the measurement result, then the display information becomes easily readable, but the arterial blood capillary is partially occluded causing the pulse signal strength to decrease
Solution Approach 1:
The display is configured to rotate or change its orientation in space, transitioning from a fixed single-direction display to a multi-directional or rotating display. This allows the display information to be viewed from different angles without requiring the user to bend their finger, thereby maintaining both ease of reading and measurement precision.
2Ease of operation
If the display is positioned for easy reading, then the user can read the measurement result without bending the finger, but the display structure becomes more complex
Solution Approach 1:
The display structure is designed to be dynamic rather than static, incorporating rotating or movable components that allow the display to change its orientation. This dynamic design enables the display to adapt to different viewing angles while maintaining a relatively simple overall structure compared to fixed multi-directional display systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise measurement by preventing arterial blood capillary occlusion and allows users to easily observe results from various angles, improving measurement accuracy and convenience.
Implementation Method 1
a beam of light from a photoelectric light emitter is arranged to pass through the organism tissue of the user, and is converted to an electrical signal after being detected by a light receiver
Implementation Method 2
it determines the oxyhemoglobins number and pulse rate by measuring the absorption rate for a selected wavelength of light wave

AI summary
There is provided a fingertip oximeter that has a plurality of display modes which are presented sequentially in a circulating way, allowing users to easily observe a measurement result from any of surrounding directions. The present invention makes users to be able to observe a measurement result of the fingertip oximeter from any of surrounding directions, without the need of bending his/her finger. Thus, any partial occlusion of the arterial blood capillary can be avoided, so that strength of the pulse will not decrease, and strength of the signal will not be affected. As a result, the precision of the measurement is improved.
