X-ray Diagnosis Handle Contact Detection for Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray diagnosis apparatuses face issues with safety and operability due to the single action method's risk of unintended operations and the double action method's increased effort requirement, leading to degraded operability.
Innovation Solution
An X-ray diagnosis apparatus with a maneuvering unit featuring a handle unit equipped with contact detecting parts that differentiate between operator contact and accidental contact, allowing the processing circuitry to control the operation of the imaging unit and table based on detection results, thereby preventing unintended operations and enhancing user safety and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the single action method is used for joystick control, then the operability is improved, but the safety is degraded due to risk of unintended operations
Solution Approach 1:
The system performs preliminary detection of contact status before executing maneuvers. The contact detecting parts detect whether the operator is properly holding the handle unit before allowing operation, preventing unintended operations while maintaining smooth control when properly held
2Reliability
If the double action method is used for joystick control, then the safety is improved, but the operability is degraded due to increased effort requirement
Solution Approach 1:
The system uses multiple contact detecting parts distributed on the handle unit to detect contact from multiple fingers. This partial detection approach provides sufficient safety verification without requiring full dual-action engagement, maintaining smooth operability while ensuring safety
3Reliability
If multiple contact detecting parts are added to the handle unit, then the safety is improved through better contact differentiation, but the device complexity increases
Solution Approach 1:
The handle unit is segmented into multiple regions with contact detecting parts distributed across different surfaces. This segmentation allows detection of contact from different fingers and directions, enabling differentiation between proper grip and accidental contact without requiring a completely complex control system

AI summary
An X-ray diagnosis apparatus according to an embodiment includes: a table including a tabletop on which a patient is placed; an imaging unit including an X-ray tube to radiate X-rays onto the patient and an X-ray detector to detect X-rays; a maneuvering unit including a handle unit that is provided with contact sensors to detect contact made by an operator and is gripped by the operator and being configured to receive a maneuver to bring into operation the imaging unit and/or the table according to an operation of the handle unit; and a processing circuitry that judges whether the imaging unit and/or the table is to be brought into operation on the basis of detection results obtained by the contact sensors and that brings the imaging unit and/or the table into operation in accordance with a result of the judgment and the maneuver performed on the maneuvering unit.
