Face Shield with U-Shaped Headrest for Sterile Surgical Drape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional face shield apparatuses used in medical procedures often fail to maintain sterilization effectively, as they may slide or obstruct the surgeon's view, and pose difficulties in accessing critical components like oxygen masks due to direct contact with the patient's face.
Innovation Solution
A face shield apparatus with a curved frame, rotatable ribs, and adjustable extensions, combined with a surgical drape that is positioned over the frame without direct contact with the patient's face, ensuring sterilization and easy access to other surgical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surgical towel or plastic is positioned directly on the patient's face using adhesive, then sterilization is maintained, but the towel may slide or obstruct the surgeon's view and adjustability is lost
Solution Approach 1:
A headrest with a U-shaped channel is introduced as an intermediary device between the patient's head and the surgical drape. The channel receives and secures the drape in place, eliminating the need for adhesive while maintaining sterilization. This intermediary structure provides both secure positioning and adjustability through the modular headrest design.
2Area of stationary object
If the surgical towel or plastic rests directly on the patient's face, then coverage is achieved, but access to critical components like oxygen masks becomes difficult
Solution Approach 1:
The headrest is segmented into a U-shaped channel structure that creates distinct zones: one for securing the surgical drape and another for accommodating oxygen masks and other surgical components. This segmentation allows the drape to cover the surgical site while leaving access paths open for critical components.
3Stability of the object's composition
If adhesive is used to secure the surgical towel, then positioning stability is improved, but patient comfort and ease of removal deteriorate
Solution Approach 1:
The U-shaped channel of the headrest acts as a mechanical intermediary that secures the surgical drape through physical containment rather than adhesive bonding. This allows the drape to be firmly positioned during surgery yet easily removed by simply lifting it away from the channel, improving both patient comfort and procedural efficiency.

AI summary
Face shield apparatuses used during medical procedures. The apparatuses may include a frame including a first and second curved member. Each of the first and second curved members may include: a first end, a second end, and an outer surface extending between the first and second end. The apparatuses may also include a bridge extending between the first end of the first curved member and the first end of the second curved member, a first rib(s) and second rib(s) rotatably coupled to the outer surface of the first curved member and second curved member, respectively. The rib(s) may extend beyond and substantially parallel to the outer surface of the first and second curved members. Additionally, the apparatuses may further include a first and second extension coupled to the first and second curved members, and a backing component releasably coupled to the first and second extensions.
