Unity Spline Particle Emission

First of hello! Been scrounging around this websites building up my coding know-how for a while now. But unfortunately I've stumbled into a problem I can't quite work out.

Simply put I want to make particles use a spline curve that I have created for movement. I have already created the spline script and editor scripts for it. And now need to work out to get the particles to use these splines. Basically I want to create a particle system that would create something similar to a heart monitor effect for now and then expand from there. Such as particle playground's spline particles.

Any suggestions or ideas would be greatly appreciated and if I should provide any other information please let me know, anything that could help me work this out or point me in the right direction would be a godsend.

Thanks in advance!
