Syringe Pump Display Unit for Filling Level Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing syringe pumps face challenges in providing a compact design while ensuring intuitive and precise monitoring of the filling level, often requiring additional sensors or compromising on space due to the need for direct visibility of the syringe or operating field.
Innovation Solution
A syringe pump with a movable cover that allows for loading and visibility of the syringe in an open position, coupled with a display unit that visualizes the filling level using operating parameters of a linear drive, eliminating the need for direct syringe visibility and enabling compact design without reducing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating field and syringe are made freely accessible and visible, then the filling level can be read directly on the syringe, but the syringe pump occupies a relatively large proportion of space
Solution Approach 1:
The patent creates a visual copy of the syringe filling level on the display unit. The display unit shows a graphical representation (such as a syringe icon with a filling indicator) that mirrors the actual syringe filling state, allowing users to monitor the filling level without physically viewing the syringe itself. This copying approach resolves the contradiction by providing visibility information through a compact digital interface rather than requiring physical space for direct syringe observation.
2Volume of moving object
If the syringe is located behind the operating front in a compact design, then space is saved, but the filling level cannot be viewed simultaneously with the operating front
Solution Approach 1:
The display unit provides a digital copy of the syringe filling level information, allowing both the operating front data and filling level to be displayed simultaneously on the same interface. This eliminates the need to physically open the operating front to view the syringe, as the filling information is replicated and presented alongside other operational parameters on the display unit.
Solution Approach 2:
The patent transitions the filling level information from a spatial dimension (physical syringe position behind the operating front) to an information dimension (digital display representation). By moving the filling level data to the display interface, the system allows simultaneous access to both operating front controls and filling level information without requiring physical repositioning or opening of compartments.
3Ease of operation
If a window or recess is provided in the operating front for viewing the syringe, then the filling level is visible, but the operating front size is reduced
Solution Approach 1:
Instead of providing a physical window or recess in the operating front, the patent creates a digital copy of the syringe filling level on the display unit. This graphical representation provides the same information function as a physical window would, but without occupying any physical space on the operating front surface, thereby maintaining the full size and integrity of the operating interface.

AI summary
A device and method for administering a medical liquid. The device includes a receiving region for receiving a hollow body containing the medical liquid and a cover connected to the receiving region. The cover is movable between an opened position and a closed position. The device also includes a drive configured for acting on the hollow body such that the medical liquid is conveyed. The device further includes a display unit for graphically displaying the filling level of the hollow body based on one or more operating parameter(s) of the drive, especially operating parameter(s) relevant to conveying the liquid.
