artificial kidney

If indications recommended blood cleansing,recommend hemodialysis patient. So there is the device "artificial kidney", which supports the systemic circulation and the functioning of the organism in its daily life.

  1. Device for blood flow. It collects biological fluid portion for further filtering.
  2. Device for implementing the dialysis solution. In this segment, the composition is prepared, sent for further interaction with the systemic circulation with a view to the future treatment of the biological fluid.
  3. Dialyzer. Centering portion with a permeable membrane, which filters water in the blood and all the toxins.

In making this procedure it is obvious thatblood first passes quality cleaning, and after returning to the patient intravenously. The session is not pleasant, but is able to maintain the viability of the organism in case of acute intoxication or renal dysfunction. When their own kidneys and liver can not cope with the load of their direct functions are performed by a special medical device.

Choosing dialyzers for hemodialysis, it does not matterforget that the main design feature is considered to be semi-permeable membrane. It is better if it is made of natural substances based on cellulose.

Synthetic bases also occur, but areincreasing the number of contraindications. It takes control of the filter, as it also tends to clog when interacting with toxins and toxic substances.
