What is a roller clamp?

A roller clamp is a type of flow regulator. Roller clamps are commonly used in iv infusion set to regulate the flow rate of the fluids and control on/off of fluid. It has a roller wheel and clamp housing. Medical users can adjust the flow rate by moving the wheel inside the slot up and down.

Structures of roller clamp

Clamp housing: The roller housing is usually made of medical grade ABS or PE. It is used to support and fix the rollers and serves as a sliding track for the roller wheel.

Roller wheel: The roller wheel is made of medical grade ABS and typically in blue or white color.

How Roller clamp works

The roller clamp works by pressing the iv tubing. The degree of compression determines the flow rate of fluid.

When medical users slide the roller wheel downwards, the pressure on the iv tubing gradually decreases, and the flow rate of fluid gradually increases; conversely, when they slide the roller wheel upwards, the pressure on the iv tubing gradually increases, and the flow rate of fluid gradually decreases.

Types of roller clamps

Standard roller clamps: Standard design for most iv infusion situations.

Safety roller clamps: The safety roller clamp, based on the normal roller clamp, adds a puncture protection seat, which can effectively prevent medical users from being needlestick.

Advantages of roller clamps

Roller clamp vs Slide clamp

Slide clamps only can quickly open and close the fluid flow; while roller clamps can not only open and close fluid, but also finely adjust the flow rate.

Roller clamp vs Robert clamp

Robert clamps typically only allow for step-by-step flow rate adjustment, while roller clamps can achieve continuous, stepless flow rate adjustment.
