Universal Drive Unit for Dual Peristaltic Pumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices for suctioning bodily fluids and supplying substances are often expensive, limited in application, and complex to handle, as they typically require separate pumps and arrangements for suctioning and supplying processes.
Innovation Solution
A versatile device with a drive unit and a connecting part that incorporates a pump head, allowing for the formation of a peristaltic pump for both suctioning and supplying, using a single drive unit and enabling easy adaptation to different applications through interchangeable connecting parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate pumps and arrangements are used for suctioning and supplying processes, then the device can perform both functions, but the device becomes expensive and complex to handle
Solution Approach 1:
The patent combines the suctioning pump and supplying pump into a single integrated pump unit with a common drive mechanism. The pump unit includes a first pump for suctioning bodily fluids and a second pump for supplying substances, both driven by the same drive unit, thereby reducing overall device complexity while maintaining dual functionality
Solution Approach 2:
The single drive unit is designed to universally drive both the suctioning pump and supplying pump through different coupling mechanisms. The drive unit can selectively couple to either the first pump or the second pump depending on the operational mode, making it a multi-functional component that eliminates the need for separate drive mechanisms
2Adaptability or versatility
If separate pumps are used for suctioning and supplying, then both functions are achieved, but the device becomes expensive to produce
Solution Approach 1:
The patent merges two separate pump systems into one integrated pump unit with a single drive, reducing the total number of components that need to be manufactured and assembled. This integration directly lowers production costs while preserving both suctioning and supplying capabilities
Solution Approach 2:
The universal drive unit designed to operate both pump types eliminates the need for manufacturing two separate drive mechanisms, thereby reducing production complexity and cost while enabling the device to perform multiple functions through a single standardized component
3Ease of operation
If a single drive unit controls both suctioning and supplying, then the device is easier to handle, but precise control of both processes becomes more challenging
Solution Approach 1:
The patent implements dynamic coupling mechanisms that allow the drive unit to selectively and independently control either the suctioning pump or the supplying pump. The coupling can be dynamically adjusted or switched between different operational modes, enabling precise control of each process while maintaining ease of operation through a single interface
Solution Approach 2:
The pump unit is segmented into functionally independent pump modules (suctioning pump and supplying pump) that can be independently controlled through the single drive unit. Each pump module maintains its own control parameters and operational characteristics, allowing precise control of each process while being managed through a unified drive interface
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 device is cost-effective, easy to handle, and versatile, allowing for simultaneous suctioning and supplying of bodily fluids and substances, with precise pressure control and reduced contamination risks, suitable for various medical applications including negative pressure wound therapy and liposuction.
Implementation Method 1
the tube, when the connecting part is connected as intended to the drive unit, in combination with the pump head, forms a peristaltic pump by way of which the fluid substance is conveyable through the tube to the human or animal body

AI summary
Provided is a container for connection to a device for suctioning bodily fluids and for supplying a fluid substance to a human or animal body, said container comprising an interior which is divided into a first region for collecting the suctioned bodily fluids and into a second region for providing the fluid substance, The first region of the interior is separated from the second region by means of a flexibly realized partition wall.
