Handheld Control Device for Medical Fluid Mixing

The patent replaces manual mechanical syringe actuation with an electronically controlled linear actuator that receives digital signals from a hand-held control device. This substitution provides precise, repeatable flow rate control through electronic means while maintaining operator control via a simplified digital interface, resolving the contradiction between control precision and ease of operation.

The patent introduces a hand-held control device with conductive pattern as an intermediary between the operator and the fluid delivery system. This intermediary translates simple finger touch inputs into precise electronic control signals for the linear actuator, enabling accurate flow rate control without requiring complex manual manipulation of the syringe mechanism.

The patent implements a dynamic control system where the linear actuator can continuously adjust its speed and direction based on real-time operator inputs from the hand-held control device. The system transitions from static fixed-parameter injection to dynamic adaptive injection, allowing flow rate modification during the injection process while maintaining automated operation through electronic control.

The hand-held control device with conductive pattern serves multiple functions: it controls the linear actuator for contrast media injection, monitors injection parameters, and provides real-time adjustment capabilities. This multi-functional device bridges automated injection with operator adaptability, allowing both automated operation and real-time parameter modification through the same interface.

The patent extends the hand-held control device with conductive pattern to control multiple fluid delivery systems simultaneously, enabling mixing of contrast media and saline. The same conductive pattern interface that controls single-fluid injection now manages multiple linear actuators or pump systems, providing multi-fluid mixing capability without proportionally increasing control mechanism complexity through electronic coordination.

The patent combines multiple fluid delivery control functions into a single hand-held control device with conductive pattern. By merging the control of contrast media injection and saline delivery into one unified interface, the system achieves multi-fluid mixing capability while minimizing the increase in device complexity through integrated electronic control architecture.

The patent implements a hand-held control device with conductive pattern that can be manufactured as a disposable component. The simple conductive pattern design allows for low-cost fabrication that maintains sufficient control reliability for single-use applications, enabling cost-effective disposable control devices that do not compromise essential performance requirements.

The patent replaces complex mechanical control mechanisms with electronic control through conductive patterns, which can be more easily manufactured as disposable components. This substitution enables the creation of reliable yet inexpensive single-use control devices, as electronic control circuits are more amenable to cost-effective disposable manufacturing compared to precision mechanical assemblies.
