Triple Access Medical Drape for Simultaneous Arterial Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical drapes do not provide simultaneous access to the patient's brachial, radial, and femoral arteries without requiring repositioning of the drape or the patient, limiting ease of access during medical procedures.
Innovation Solution
A triple access medical drape with a main sheet and adjustable arm board covers, featuring openings for femoral, brachial, and radial artery access, adhesive rings for securement, and a clear anesthesia window, constructed from fire retardant, chemical resistant, and biodegradable materials, allowing for flexible positioning and access without re-draping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-access drape is used, then the drape structure is simple, but multiple arterial access points cannot be obtained without repositioning the patient or drape
Solution Approach 1:
The drape is divided into distinct functional segments: a main body portion covering the patient's torso and multiple separate arm board covers (first and second arm board covers) that can be independently positioned. Each arm board cover contains openings for accessing different arterial sites (brachial and radial arteries), while the main body provides access to the femoral artery. This segmentation allows each portion to be optimized for its specific access point while maintaining overall drape integrity.
Solution Approach 2:
The drape is designed as a multi-functional device that simultaneously provides access to multiple arterial sites (femoral, brachial, and radial arteries) through a single device. The main body portion and arm board covers together create a universal access system that eliminates the need for separate drapes or repositioning for different arterial accesses, allowing one drape to serve multiple procedural needs.
2Ease of operation
If the drape is made adjustable to accommodate different arm positions, then access flexibility is improved, but the drape requires more components and adjustment mechanisms
Solution Approach 1:
The arm board covers are designed with dynamic positioning capabilities, allowing them to be adjusted to accommodate different arm positions and patient anatomies. The covers can be positioned at various angles and orientations while remaining attached to the main drape body, enabling the drape to adapt to different procedural requirements and patient positions without requiring complete re-draping.
3Productivity
If multiple openings are provided for different arterial accesses, then procedural efficiency is improved, but maintaining sterility becomes more difficult
Solution Approach 1:
The drape incorporates localized protective features at each access site, including adhesive rings positioned around specific openings and protective panels that can be selectively removed or opened. Each opening (for femoral, brachial, or radial artery access) has its own dedicated protective elements, allowing the sterile field to be maintained at each location independently. This localized protection enables multiple access points while preserving sterility through targeted rather than universal exposure.

AI summary
A medical drape, including a main sheet having at least one opening for access to a patient's femoral artery, and at least one adjustable arm board cover substantially located at one end of the main sheet wherein the adjustable arm board cover includes at least one opening for access to the patient's brachial artery and at least one opening for access to the patient's radial artery.
