Solution Overview
Problem
Existing phototherapeutic apparatuses lack a safe and reliable method for users, such as patients or nursing attendants, to accurately set and change treatment protocols for irradiation with narrow-band UVB light at home, leading to potential errors in positioning and irradiation settings.
Innovation Solution
A phototherapeutic apparatus with a probe and a control unit that includes a reader for mobile memory media to load treatment protocols, an operation indication unit to guide users on correct positioning, and a communication system to allow medical institutions to remotely change protocols, ensuring accurate and safe light irradiation based on set values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a phototherapeutic apparatus is made portable with a probe held by a user, then accessibility and ease of use at home are improved, but positioning accuracy and operational safety deteriorate due to lack of professional guidance
Solution Approach 1:
An operation indication unit acts as an intermediary between the treatment protocol and the user, providing visual or auditory guidance on where to position the probe. This mediator ensures that even non-professional users can accurately target affected areas without requiring medical expertise, thus maintaining positioning accuracy while enabling home use.
Solution Approach 2:
Treatment protocols are pre-configured with precise positioning information and irradiation parameters by medical professionals before home use. The operation indication unit displays this preliminary information to guide the user's positioning action, ensuring accuracy is established in advance rather than requiring real-time professional supervision.
2Reliability
If treatment protocols are pre-set in the apparatus, then treatment consistency and safety are improved, but flexibility to adapt to changing medical conditions deteriorates
Solution Approach 1:
The treatment protocol storage system is designed to be dynamic rather than static. Multiple protocols can be stored and switched based on changing medical conditions. The system allows transition from fixed pre-set protocols to adaptable protocol selection, maintaining consistency through structured options while providing flexibility when medical needs change.
Solution Approach 2:
The apparatus enables modification of protocol parameters such as irradiation intensity, duration, and frequency based on treatment progress. This allows the system to maintain initial treatment consistency while adapting parameters over time in response to medical feedback or changing conditions, resolving the contradiction between consistency and flexibility.
3Adaptability or versatility
If users manually set irradiation parameters, then operational flexibility is improved, but risk of setting errors and safety issues increases
Solution Approach 1:
The operation indication unit provides self-guiding information to users, enabling them to independently and accurately set irradiation parameters without professional assistance. This self-service mechanism reduces setting errors by guiding non-experts through proper parameter selection while maintaining the flexibility to adapt to different treatment scenarios.
Solution Approach 2:
The system provides feedback to users about appropriate parameter settings based on the selected treatment protocol and detected affected area characteristics. This feedback mechanism prevents setting errors by guiding users toward safe and effective parameter combinations while maintaining operational flexibility for different treatment situations.
4Adaptability or versatility
If medical institutions remotely modify treatment protocols, then treatment adaptability and medical supervision are improved, but system complexity and communication requirements increase
Solution Approach 1:
The communication unit is designed with multi-functionality, serving both simple protocol updates and comprehensive medical supervision functions. This universal design allows the system to handle various communication tasks through a single integrated interface, reducing overall system complexity while enabling remote protocol modification and medical oversight.

AI summary
Provided is a phototherapeutic apparatus including: a probe that is held and operated by a user and provided with a photo-irradiation unit that performs irradiation with light beams; and a body provided with a control unit that controls the light beams. The body is provided with a read unit that reads a treatment protocol registered in an IC card (mobile memory medium), and a monitor (operation indication unit) that indicates a region to be irradiated with the light beams to the user, the region being set in the treatment protocol, and the control unit causes the monitor to indicate the region to be irradiated and causes the photo-irradiation unit to perform the irradiation with the light beams at a set value set in the treatment protocol. It is possible to perform the irradiation with the light beams in accordance with the treatment protocol and safely use the phototherapeutic apparatus.
