Vacuum Wound Device Pump Canister Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum treatment devices for wounds are not cost-effective and lack design features that enhance maintenance, readability of the filling level, and wearing comfort, especially in mobile applications.
Innovation Solution
A compact device design where the disposable canister has a recess for the pump, ensuring secure fixation, easy cleaning, and improved visibility of the filling level, along with a two-point suspension system for balanced weight distribution and enhanced visibility of the filling level indicator, which is also illuminated for better readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the pump is mounted on the pump housing in a conventional manner, then the device structure is simple, but the cleaning accessibility is poor and maintenance is difficult
Solution Approach 1:
Instead of mounting the pump on the housing as conventionally done, the patent inverts the arrangement by placing the pump inside the disposable canister. This inversion allows the pump to be accessed and cleaned easily by simply removing the canister, while the permanent housing remains simple and cleanable.
Solution Approach 2:
The patent applies the disposable principle by making the canister (which contains the pump) a disposable component. The pump is integrated into the canister that is discarded after use, eliminating the need for complex cleaning and maintenance of the pump itself, while the housing remains a simple permanent structure.
2Measurement precision
If the canister is made transparent for filling level visibility, then the readability is improved, but the structural strength and sealing are compromised
Solution Approach 1:
The patent applies local quality by making only specific portions of the canister transparent (the walls) while keeping other portions opaque (the lid and base). This allows filling level visibility through the transparent walls while maintaining structural strength and sealing through the opaque components that can be made from more robust materials.
3Adaptability or versatility
If the device is designed for stationary use only, then the structural stability is high, but the adaptability to mobile use is limited
Solution Approach 1:
The patent applies universality by designing the device to serve both stationary and mobile functions. The pump-inside-canister configuration with the canister serving as both container and pump housing creates a self-contained unit that can be easily moved or mounted on patients, providing multi-functionality across different usage scenarios.
4Ease of manufacture
If the pump is integrated into the disposable canister, then the maintenance cost is reduced and cleaning is simplified, but the manufacturing complexity increases
Solution Approach 1:
The patent applies merging by combining the pump and canister into a single integrated unit. The pump housing forms part of the canister structure, with the canister walls enclosing the pump. This integration eliminates separate components, simplifying maintenance (the entire unit is disposable) while the manufacturing complexity is managed through modular design where the pump is a standard component placed within the molded canister structure.
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 design provides a cost-effective, user-friendly, and comfortable vacuum treatment device for wounds, facilitating easier maintenance and improved readability of the filling level, even in mobile use.
Implementation Method 1
a container partially evacuated by a vacuum pump withdraws ichor via a drainage port from a wound
Implementation Method 2
The suction vacuum produced by the pump must be adapted to the type of wound

AI summary
A device for vacuum treatment of wounds, the device having a disposable canister for receiving a suctioned wound exudate, and a vacuum pump. The disposable canister is designed to partially enclose the vacuum pump, which is inserted into the canister, and to thereby fix it against movements in non-inserting directions. The structure of the device is used mainly in a stationary mode and occasionally is used in a mobile mode when worn by patients.
