Movable Vial Platform Synchronization for Precise Fluid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pharmaceutical preparation systems lack efficient mechanisms for fluid interface management between different containers, such as IV bags and syringes, which hinders precise and automated fluid transfer processes.
Innovation Solution
A pharmaceutical preparation system with intersecting axes, featuring a movable platform and manipulator, allows for synchronized linear displacement along these axes to establish a fluid interface between containers, enabling precise fluid transfer operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a movable platform with intersecting axes is used to enable synchronized linear displacement of containers, then fluid transfer precision and automation are improved, but device complexity increases
Solution Approach 1:
The patent employs a movable platform that can dynamically adjust its position along the first axis (vertical displacement) while the manipulator moves independently along the second axis (horizontal displacement). This dynamic positioning capability enables precise fluid interface alignment between containers of different types and sizes, resolving the contradiction between precision and complexity by making the system adaptable rather than fixed
Solution Approach 2:
The patent introduces a two-axis coordinate system with intersecting first and second axes. The platform provides displacement along the first axis while the manipulator provides displacement along the second axis. This dimensional separation allows independent control of vertical and horizontal positions, achieving precise fluid transfer through coordinated multi-axis movement rather than complex single-axis mechanisms
2Extent of automation
If synchronized actuation of multiple mechanisms is implemented to enable fluid interface between containers, then automation extent is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it actuates the platform along the first axis, actuates the manipulator along the second axis, and synchronizes their movements to achieve fluid interface. This multi-functional control system reduces the need for separate specialized mechanisms for each function, achieving high automation while managing complexity through integrated control
Solution Approach 2:
The synchronized actuation system uses feedback from sensors that detect the positions of the platform and manipulator, as well as the alignment status of container interfaces. This feedback enables the controller to adjust and coordinate movements in real-time, achieving precise automated fluid transfer while maintaining system manageability through closed-loop control

AI summary
A pharmaceutical preparation system defining a vertical axis and a horizontal axis is provided, including: at least one platform onto which a vial holder is mounted, the vial holder configured to hold and to pivot at least one vial; a lift mechanism operably connected to the platform for raising or lowering the platform along the vertical axis; and a controller configured for: a. instructing the lift mechanism to raise or lower the platform; b. instructing the vial holder to pivot the vial to assume an upright orientation for injecting fluid into the vial or an inverted orientation for drawing fluid from the vial; c. synchronizing actuation of the lift mechanism and the vial holder such that a level to which the platform is moved is correlated one or both of: the orientation of the vial, presence of one or more components connected to the vial and aligned vertically with respect to the vial.
