Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser lancing devices lack effective mechanisms for removing smoke and foreign substances generated during blood collection, and they do not adequately address thermal damage or patient pain relief, while also risking accidents due to improper laser irradiation.
Innovation Solution
A laser lancing device incorporating a fan unit to suck smoke and foreign substances, a cooling system to prevent thermal damage, and an interlock mechanism to ensure safe laser irradiation, featuring a main body with a laser resonator, beam barrel, window barrel, cap part, and communication pipe for air flow and cooling medium distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser resonator is used to generate and output laser for skin perforation, then blood collection capability is improved, but thermal damage to treatment area and patient pain increase
Solution Approach 1:
A cap part is introduced as an intermediary component between the laser output and the patient's skin. The cap part includes a cooling hole through which a communication pipe passes, allowing cooling medium to flow and cool the treatment area. This intermediary structure enables the laser to perform its blood collection function while simultaneously providing cooling to reduce thermal damage and pain.
Solution Approach 2:
The harmful thermal effect is extracted and separated from the useful laser function. By introducing a dedicated cooling system with communication pipes and cooling holes in the cap part, the patent extracts the thermal damage component and counteracts it independently, allowing the laser to maintain its blood collection capability without causing excessive thermal damage or pain.
2Ease of operation
If laser irradiation is enabled without safety interlock, then operation simplicity is improved, but accident risk increases
Solution Approach 1:
The interlock unit is configured to require preliminary action - the cap part must be properly installed on the main body before the laser can be operated. The interlock unit includes a detection portion that detects whether the cap part is correctly positioned, and only when detected does it enable laser irradiation. This preliminary safety check prevents accidents while maintaining operational simplicity through automatic detection.
3Device complexity
If smoke and foreign substances are not removed, then device complexity is reduced, but treatment area visibility and hygiene deteriorate
Solution Approach 1:
The cap part is designed with multi-functionality: it not only serves as a protective cover and includes cooling holes for thermal management, but also incorporates a communication pipe that functions as a smoke and foreign substance removal channel. By connecting the fan unit to the cap part, the same structural component handles multiple functions including cooling and debris removal, reducing overall device complexity while improving treatment area conditions.
