Ultrasonic Probe Position Detection for Automated Vascular Regurgitation Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic diagnostic apparatuses for vascular regurgitation testing require manual operation, leading to user inconvenience and prolonged test times due to the need for manual placement and movement of probes and pressure devices.
Innovation Solution
An ultrasonic diagnostic apparatus with a pressure device divided into regions, controlled by a controller that automatically contracts or expands blood vessels and operates in a predetermined order, using a detector to determine the probe's position and generate color Doppler images to assess regurgitation, allowing for automated workflow-based testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used for vascular regurgitation testing, then the examiner can perform the test, but user inconvenience increases and test time is prolonged
Solution Approach 1:
The pressure device is equipped with a detector that automatically detects the probe position and triggers the regurgitation test without requiring manual operation. The device performs self-service by autonomously determining when and where to apply pressure based on probe detection, thereby eliminating user inconvenience and reducing test time
Solution Approach 2:
The manual mechanical operation of placing and moving the probe and pressure device is replaced by an automated detection and control system. The detector automatically identifies probe position and the controller manages the pressure application sequence, substituting manual mechanical actions with an automated electromechanical system
2Ease of operation
If the pressure device is continuously moved during the test, then the test can be performed, but user inconvenience increases
Solution Approach 1:
The pressure device is divided into multiple independent pressure chambers (first, second, third chambers) that can be sequentially activated. This segmentation allows the device to remain stationary while different regions are pressurized in sequence based on probe position, eliminating the need for continuous movement and reducing operational complexity
Solution Approach 2:
The detector continuously monitors probe position and pre-determines which pressure chamber should be activated next. This preliminary detection and preparation of pressure application sequences eliminates the need for continuous device movement during the test, as the system is already prepared to apply pressure at the correct location and time
