Hemodiafiltration Machines – At a Glance

Hemodiafiltration, commonly known as HDF is a kind of renal replacement therapy that uses convective along with diffusive clearance, which is utilized in standard hemodialysis. When compared with standard hemodialysis, hemodiafiltration removes middle molecular weight solutes more efficiently.

What is Hemodiafiltration?

Hemofiltration, sometimes, is combined with hemodialysis and it is then termed as hemodiafiltration. In this process, blood is pumped through the blood section of the high flux dialyzer. This also uses ultrafiltration at a high rate. This results in an increased rate of movement of solutes and water from the blood to the dialysate.

This is to be substituted by a fluid that is infused into the bloodline directly. The dialysis solution can also be run through the dialysate sector of the dialyzer. The combination of hemofiltration and hemodialysis is particularly effective as it leads to the effective removal of small and large molecular weight solute.

What is a Hemodiafiltration Machine?

Hemodiafiltration machines are mainly used in case of kidney failure or kidney dysfunction. Such machines are primarily used in intensive care units. Renal failure is one of the common health disorders that are on the rise due to the increase in the elderly population. Despite several medical advancements in renal replacement therapy, there is a growing need for such machines.

How does a hemodiafiltration machine work?

A hemodiafiltration machine works in the following way:

  • Blood flows from the body of the patient into the hemodialysis machine.
  • If blood thinner has been prescribed by the doctor, it will be added so that the blood does not clot when it is inside the machine.
  • A pump and a pressure monitor work together so that the flow is maintained at the proper rate.
  • The blood gets filtered in the dialyzer.
  • The dialysate solution goes into the dialyzer and removes the waste from the blood.
  • The used-up dialysate solution is eliminated from the machine.
  • A pressure monitor and an air trap ensure that the blood is safe enough to return to the body.
  • The cleaned blood enters the body.

What are the common features of Hemodiafiltration Machines?

Though there are several options available for patients who want to have hemodiafiltration machines at home, there are certain features that are the most preferred ones. These are as follows:

Easy installation

Advanced hemodiafiltration machines are very easy to set up. They normally do not require any additional and expensive modifications that you need to make.


Good quality hemodiafiltration machines are designed in such a way so that they can be easily transported from one place to another. Some models also come in hard-sided aluminum cases that provide extra protection to the machine while traveling.

Easy to use

An effective and efficient hemodiafiltration machine is easy to handle so that patients who do not have any training or expertise can also use it. An easy to operate machine will reduce both time and effort and help in conducting regular treatments. Some machines also come with detailed manuals so that they can be easily operated.
