Surgical Drape With Removable Opaque Screen For Patient Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical drapes used in C-section procedures obscure the mother's view of her newborn immediately after delivery, preventing an immediate connection between the mother and child.
Innovation Solution
A surgical drape with a main sheet, a fenestration for surgical access, and a combination of a substantially transparent sheet and an opaque screen that can be attached and detached to allow the patient to view the surgical area while maintaining a sterile field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional solid surgical drape is used to maintain a sterile field and occlude the patient's view, then the sterile field is maintained and the patient's view is occluded, but the patient cannot see the newborn immediately after delivery, preventing immediate mother-child connection
Solution Approach 1:
The drape is segmented into multiple functional layers: a main sheet for sterile field maintenance, a transparent sheet for visual access, and an opaque screen for selective occlusion. This segmentation allows each layer to perform its specific function independently while working together as a unified system.
Solution Approach 2:
The opaque screen is designed to be dynamically reconfigurable - it can be attached to block the patient's view, detached to allow viewing, and repositioned as needed. This dynamic capability enables the system to adapt between maintaining sterility and enabling visual connection based on procedural needs.
2Loss of information
If a transparent sheet is used to allow patient viewing of the surgical area, then the patient can see the newborn, but the sterile field may be compromised if the viewing mechanism introduces contamination risk
Solution Approach 1:
The transparent sheet acts as an intermediary that allows visual transmission while maintaining the physical barrier of the sterile field. The opaque screen serves as a controllable intermediary that can block or permit viewing without compromising sterility, as it attaches to and detaches from the transparent sheet without entering the sterile zone.
Solution Approach 2:
The drape utilizes flexible thin film structures that can conform to the surgical environment while maintaining integrity. These flexible films allow for the creation of viewing pathways without rigid structures that could compromise the sterile barrier, enabling visual access while preserving field sterility.
3Ease of operation
If an opaque flap is attached and detached to control patient viewing, then the patient can alternately see and not see the surgical area, but the flap may be folded into the surgical field causing contamination
Solution Approach 1:
The opaque screen is positioned in a dimension outside the sterile surgical field, attached to the transparent sheet which forms part of the non-sterile drape structure. This spatial arrangement allows the screen to be moved and repositioned without entering or contaminating the sterile field, solving the contamination risk while maintaining viewing control.

AI summary
Disclosed is a surgical drape configured to selectively allow or block a patient's view of the surgical field, as is desired in Caesarean section operations. Generally, the drape includes a main sheet, a substantially transparent sheet attached to the main sheet proximal the patient's head, and a substantially opaque screen attached to the patient-facing side of the substantially transparent sheet. This substantially opaque screen occludes the patient's visual access through the substantially transparent sheet but may be at least partially removed to permit the patient viewing access through the substantially transparent sheet towards the area of the surgery, without compromising the sterility of the surgical field. Desirably, the drape is provided with an adhesive strip disposed on the sheet or screen to permit reconnection to thereby again occlude the patient's view through the sheet.
