The BQ Medical provides high quality Robert Clamp, Slide Clamp, Roller Clamp and Flow Regulator, are used to regulate the flow of I.V. fluid from the infusion set to the intravenous cannula. 

The BQ Medical Roller Clamp is what we used to control the rate at which the IV fluid infuses. 
The BQ Medical Robert Clamp and Slide Clamp are used when we want to completely stop the IV from flowing, without having to adjust the roller clamp.
The BQ Medical Flow Regulator is used to regulate the flow of I.V. fluid from the infusion set to the intravenous cannula and having a smooth kink resistance tube, ensure a constant flow rate.
