How many refills on average of syringe diluent/water are required to remove all pill particles from pill pouch?

That is a really good question. It would be very hard to say for sure but will depend on a couple factors:

* How well the pill particles are dissolved. That is a function of how long the mixture is shaken and how well the pill dissolves in liquid. Some pills that have coatings on them are more difficult to dissolve. A trial should be performed on these pills to determine if they are worth trying to dissolve in liquid.

* How accurate the dose needs to be. If the dose needs to be accurate, more flush cycles will be required.

Our tests have shown anywhere from 2 to 5 flush cycles get most of the medication out of the pouch. One flush cycle almost always leaves quite a bit of residual unless a lot of time is taken to shake the mixture to dissolve the medication.
