Question: 1 / 400

How does a Jackson Pratt drain remove fluid?

By creating oncotic pressure

Using positive pressure from a syringe

Utilizing negative pressure in a bulb

The Jackson Pratt drain effectively removes fluid by utilizing negative pressure within its collection bulb. This system relies on a flexible, bulb-like container that is compressed before it is connected to the drainage tube. Once the bulb is compressed and then allowed to expand, the negative pressure created within the bulb draws fluids from the surrounding tissues into the drainage system.

This method is particularly beneficial following surgical procedures, as it helps prevent fluid accumulation at the surgical site, promotes healing, and reduces the risk of infection. The drainage process is active, relying on the suction generated by the negative pressure, which distinguishes it from passive systems such as gravitational drainage that depend solely on the position of the drain relative to the fluid source.
