Lever-Actuated Dressing Applicator for Sterile Wound Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dressing dispensers do not assist in applying dressings to needle stick sites or wounds, leading to potential exposure to hazardous biomedical materials and inconsistent application protocols, with healthcare professionals often relying on nonsterile methods and patient assistance.
Innovation Solution
A handheld dressing applicator that dispenses and applies dressings with pressure, using a lever-actuated mechanism to position and secure the dressing pad and tape, ensuring a sterile and consistent application process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a dressing dispenser is used to dispense dressings, then the dispensing function is improved, but the application assistance function deteriorates (healthcare professionals still must manually apply the dressing)
Solution Approach 1:
The patent combines the dressing dispensing function and the application assistance function into a single integrated device. The applicator includes a dispensing mechanism that delivers the dressing directly to the application site while simultaneously providing mechanical assistance for proper positioning and adherence, eliminating the need for separate manual application steps
2Adaptability or versatility
If manual dressing application is performed, then flexibility in application method is maintained, but exposure to hazardous biomedical materials increases
Solution Approach 1:
The patent introduces an intermediary device (the applicator) that acts as a barrier between the healthcare professional and the hazardous biomedical materials at the needle stick site. The applicator mechanically applies the dressing without requiring the professional to directly touch the contaminated area, while still allowing flexibility in application technique through its design features
3Ease of manufacture
If nonsterile dressing materials are used with patient assistance, then resource utilization is improved, but contamination risk increases
Solution Approach 1:
The patent designs the applicator to be self-sufficient in maintaining sterility through its own structural features and operation mechanism. The device includes sealed compartments, sterile barriers, and controlled release mechanisms that preserve the sterility of dressing materials throughout storage and application, eliminating reliance on patient assistance and preventing contamination while efficiently utilizing medical resources
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dressing applicator provides a sterile and consistent method for applying dressings, reducing exposure to hazardous materials and standardizing the application process, while allowing for easy manipulation and sterilization.
Implementation Method 1
a handle/magazine spring is positioned within the cavity of the handle/magazine so as to provide a spring biasing force to any dressing pad contained within the cavity of the handle/magazine
Implementation Method 2
The dressing applicator comprises a lever-actuated mechanism that biases various arms in order to position and deposit the dressing pad and tape portion onto a surface
