Portable Vacuum Pump Wound Dressing for Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large and infected wounds face challenges in closure due to reduced blood flow, leading to diminished oxygen and nutrient supply, and increased difficulty in microbial infection management, which existing wound dressings struggle to address effectively in terms of ease of use, efficiency, portability, and negative pressure control.
Innovation Solution
A self-contained wound dressing apparatus with a portable peristaltic vacuum pump system and collection canister, allowing for subatmospheric pressure application and fluid removal, integrated with a body support bag for patient mobility, and incorporating absorbent materials and medicaments to promote healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If negative pressure therapy is used to remove wound fluids, then wound healing is facilitated, but device portability and ease of use deteriorate
Solution Approach 1:
The patent combines the vacuum pump, collection canister, power source, and control systems into a single integrated portable unit that can be worn by the patient. This merging of components resolves the contradiction by maintaining effective negative pressure therapy while achieving portability and ease of use, allowing patients to move freely without being constrained by separate bulky equipment.
Solution Approach 2:
The invention transitions from traditional stationary negative pressure systems to a wearable portable system by adding the dimension of mobility. The apparatus is designed to be carried on the patient's body, transforming the treatment from a fixed hospital-based intervention to a mobile home-care solution that maintains therapeutic effectiveness while improving accessibility.
2Productivity
If complex negative pressure control is implemented, then wound fluid removal efficiency is improved, but device complexity increases
Solution Approach 1:
The portable apparatus incorporates automated control systems that monitor and regulate negative pressure without requiring constant manual intervention. The device includes pressure sensors, flow meters, and microprocessors that automatically adjust pumping parameters to maintain optimal therapy levels, resolving the contradiction by achieving high removal efficiency through self-regulating mechanisms rather than complex manual control systems.
Solution Approach 2:
The system incorporates feedback mechanisms including pressure sensors within the wound dressing, flow meters in the collection canister, and microprocessors that continuously monitor treatment parameters. This feedback loop allows the device to automatically adjust negative pressure levels based on real-time wound conditions, maintaining high fluid removal efficiency while simplifying user interaction through automated control.
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
Facilitates efficient removal of wound fluids, enhances wound healing by maintaining optimal pressure levels, and supports patient mobility without constraints, improving the closure of large and infected wounds.
Implementation Method 1
a portable vacuum pump in fluid communication with the wound dressing member for applying subatmospheric pressure to facilitate removal of fluid from the wound dressing member
Implementation Method 2
The vacuum pump preferably includes a peristaltic vacuum pump
Implementation Method 3
The collection canister may include an absorbent material to contain the fluid removed from the wound dressing member

AI summary
The composite wound dressing apparatus promotes healing of a wound via the use of a vacuum pump. The vacuum pump applies a vacuum pressure to the wound to effectively draw wound fluid or exudate away from the wound bed. The vacuum pump is tethered to the wound dressing and is portable, preferably, carried by the patient in a support bag, which permits patient mobility. Moreover, the patient does not need to be constrained for any period of time while exudate is being removed from the wound.
