Operating Table Display Elapsed Tilt Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating table systems do not provide a way for medical personnel to easily track the elapsed time a patient is held in a tilted posture, which can lead to prolonged pressure on the patient and potential for decubitus (bedsore) without direct visual access to the patient's position.
Innovation Solution
An operating table system with a display that shows elapsed time in a tilted posture, integrated with a movement mechanism and operation controller, allowing medical staff to monitor and adjust the table's posture through user input devices like joysticks and mode settings, ensuring timely posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating table is tilted to facilitate patient treatment positioning, then the ease of operation for medical staff is improved, but the risk of prolonged pressure on the patient increases leading to potential decubitus
Solution Approach 1:
The system implements feedback by displaying elapsed time information on the display unit when the table is tilted. This provides continuous feedback to medical staff about how long the patient has been in a tilted position, enabling them to monitor and adjust positioning to prevent prolonged pressure. The feedback loop connects the table's tilted state to visual time information, allowing proactive prevention of decubitus while maintaining treatment accessibility.
2Stability of the object's composition
If the operating table remains in a fixed tilted posture for extended periods, then the patient can be maintained in a stable treatment position, but the likelihood of decubitus increases due to prolonged pressure
Solution Approach 1:
The display unit provides continuous feedback on elapsed time, allowing medical staff to monitor the duration of tilted positioning. This enables them to maintain stable treatment positions when necessary while being alerted to adjust positioning before decubitus occurs. The feedback mechanism bridges the need for positional stability with the need to prevent prolonged pressure.
Solution Approach 2:
The system performs preliminary action by providing time information before decubitus actually occurs. By displaying elapsed time in advance, the system allows medical staff to take preventive action (adjust patient positioning) before harmful effects manifest, rather than reacting after damage has occurred.
3Object-affected harmful factors
If real-time monitoring of tilted posture duration is implemented, then the risk of decubitus is reduced, but the device complexity increases
Solution Approach 1:
The feedback mechanism uses existing table control system components (control unit and display unit) to provide elapsed time information. By leveraging already-present system elements rather than introducing entirely new monitoring hardware, the solution achieves decubitus prevention functionality with minimal increase in overall system complexity.

AI summary
An operation device according to one or more embodiments may include: a display; a move operation receiving unit that receives, from a user, a move operation to move a table on which a patient can be placed of an operating table; and an operation controller. In a condition in which the table is put in a tilted posture in accordance with the move operation, the operation controller may cause the display to display an elapsed time in the tilted posture.
