Skin Cover Unit with Angled Wall Stabilizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic-transparent surgical skin cover units fail to maintain optimal contact with flat skin areas due to instability of the upstanding wall, leading to inferior ultrasonic transmission and practical limitations in puncture device insertion procedures.
Innovation Solution
A skin cover unit with a flexible ultrasonic-transparent window and a stabilizing frame, featuring a bending region that allows the wall to be angled relative to the window, supported by a non-resilient stabilizer to maintain orientation and stability, ensuring effective skin contact and ultrasound transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the film is made stiff to hold the wall upright, then the wall stability is improved, but the skin contact quality deteriorates
Solution Approach 1:
The device is divided into two distinct components: a flexible window for skin contact and a separate upstanding wall for probe support. This segmentation allows each part to have optimized properties - the window remains flexible for good skin contact while the wall provides structural support for probe stability.
Solution Approach 2:
A bending region acts as an intermediary connection between the flexible window and the upstanding wall. This bending region allows the wall to be positioned at an angle relative to the window, enabling the wall to stand upright while the window maintains flexible skin contact.

AI summary
An insertion site for a cannula (23) on a skin (8) of a patient is prepared by applying a skin cover unit (1) of the type comprising a window (2) and a wall (3) in extension of the window (2) and connected to the window (2) by a bending region (4) for bending the wall (3) into an angled orientation relatively to the window (2); wherein the win-dow (2) comprises a stabilizing frame (5) and an ultrasonic-transparent flexible sheet (6) within the frame (5). The flexible sheet (6) is glued onto the skin (8) of the patient for ultrasonic investigation of the insertion site through the flexible sheet (6). By bending the bending region (4), the angular orientation of the wall (3) is adjusted into an approximately perpendicular orientation relatively to the window (2) for separating the insertion site from the flexible sheet (6) by the wall (3). The cover unit (1) in or at the bending region (4) comprises a stabilizer (9) that is configured for maintaining the angled orientation between the wall (3) and the window (2) by a stabilizing action of the stabilizer (9).
