Hi Deepa,

A dialyzer is a machine that is used to purify the blood artificially. 

A dialyzer consists of several hollow fibre, which serve as a semi permeable membrane. The small impurities present in the blood move out of the fibres through the holes, while the larger particles (blood cells and other components) are retained in the blood. 

Also the hollow fibres are surrounded by a dialysis fluid; which helps to draw out excessive water and uremic substances from the blood. 

The purified blood is then returned into the patients body.
