Device And Electronic Controller For Syringe Piston Control

An electronic controller module for controlling displacement of a syringe piston within a syringe that comprises a hollow barrel to contain a fluid, the syringe piston being slidably engaged in the hollow barrel, wherein the electronic controller causes an outward movement of the syringe piston within the barrel, the electronic controller module comprising:

• an output port;
• a processor module for determining a prescribed speed of the outward movement, wherein the processor module:
• sends an initial motor command via the output port to activate a motor at an initial motor speed, wherein the motor is operatively connected to the syringe piston to cause the outward movement;
• an input port that receives speed measurements;
• wherein the processor module attempts to match the prescribed speed based on the speed measurements by sending successive further motor commands via the output port, each further motor command comprising a further motor speed;
• and
• wherein the electronic controller module is within a handheld syringe control system.
