Transparent Inspection Portion for Suction Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing suction devices for negative pressure wound therapy systems are cumbersome to attach correctly to the wound cover member, making it difficult to establish appropriate fluid communication and potentially hindering the effectiveness of the therapy.
Innovation Solution
A suction device with an attachment portion, a fluid inlet, and a connection portion that includes a transparent inspection portion to facilitate alignment with the wound cover member opening, allowing for clear visualization and easy placement, and a partition wall to maintain structural integrity under negative pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction device is attached to the wound cover member using an adhesive layer, then the fluid communication can be established, but the operation becomes cumbersome and difficult to position correctly
Solution Approach 1:
The patent applies transparency (optical property) to the connection portion of the suction device, allowing the user to visually align the fluid inlet with the wound cover member opening during attachment. This optical feature guides correct positioning without requiring complex adhesive application procedures, thereby improving ease of operation while maintaining reliable fluid communication.
2Reliability
If the fluid inlet is placed directly over the wound cover member opening, then appropriate fluid communication is achieved, but the attachment operation becomes cumbersome
Solution Approach 1:
The transparent connection portion acts as an intermediary visual aid between the fluid inlet and the wound cover member opening. It allows the user to see through the device body to align the inlet with the opening, serving as a mediating element that simplifies the attachment process while ensuring correct positioning for reliable fluid communication.
3Strength
If the connection portion is made opaque for structural integrity, then the device is stronger, but alignment and positioning become difficult
Solution Approach 1:
The patent applies local quality by making only the connection portion transparent while keeping the rest of the device structure opaque. This localized transparency provides the necessary visual guidance for alignment, while the surrounding opaque structure maintains structural integrity. The different optical properties are applied to different parts of the device according to their specific functional requirements.

AI summary
The present invention relates to a suction device (22). The suction device (22) comprises an attachment portion (32) adapted to be attached to a wound cover member (18). The suction device (22) comprises a fluid inlet (28) which is at least partially circumscribed by the attachment portion (32). The suction device (22) also comprises a fluid outlet (30). The suction device (22) further comprising a connection portion (36) adapted to, at least during one operation condition of the suction device (22), provide a fluid communication between the fluid inlet (28) and the fluid outlet (30). The connection portion (36) comprises an inspection portion (38) that is transparent to thereby facilitate the positioning of the suction (22) device relative to the wound cover member (18).
