Infusion Pump Setup


Remote Connection of Syringe and Needle

With standard infusion pumps it is often necessary to dispense the liquid a distance away from where the syringe is mounted into the pump. A common technique for accomplishing this is by stretching a piece of PE 50 tubing over the end of the syringe needle. The problem with this approach is that the PE50 tubing is flexible and often difficult to prime.  This adds elasticity to the system so when a dispense is attempted it is possible that the tubing will stretch or the trapped air bubble will compress instead of dispensing liquid from the needle. Hamilton has minimized these sources of error by selecting PEEK tubing which is designed to support high pressure and has almost no dead volume so it is simple to fully prime.  Below are examples of four possible configurations that can be accomplished with these components.
