What is dialyzer?

Dialyzer also called Hemodialyzer, is a pipeline and container for solute exchange between blood and dialysate, and is a key part of hemodialysis treatment. The dialyzer is mainly composed of a support structure and a hollow fiber membrane. It is a semi-permeable membrane that only allows molecules smaller than the membrane pore size to pass through. The membrane materials are improved cellulose membranes and synthetic membranes.

Dialyzer function

Hemodialysis is a form of renal replacement therapy for patients with acute and chronic renal failure. By draining the blood from the body to the outside of the body, through a dialyzer composed of numerous hollow fibers, the blood and the body's concentration of electrolytes are similar. In the root hollow fibers, material exchange occurs through diffuse convection.

Dialyzer function is mainly to remove the metabolic wastes in the dialysis patients, maintain the electrolyte and acid-base balance in the patients, and at the same time remove the excess water in the uremia patients, and return the blood after dialysis to the patients. Generally, maintenance hemodialysis patients Hemodialysis treatment is required about three times a week.

How dialyzer works?


What items need for hemodialysis treatment?

Dialysis products:
1. Dialyzer 
2. Blood tubing set
3. AV fistula needle
4. Dialysis catheter
Dialysis equipment:
1. Dialysis machine
2. Dialyzer reprocessing machine

Dialyzer types

By flow: high flow dialyzer, medium flow dialyzer, low flow dialyzer 
By hollow fiber(popular type): PES dialyzer, PS dialyzer, TAC dialyzer 

Dialyzer price

In market, different brand has own sale price strategy, but generally, dialyzer price from USD15~USD20/pcs

Dialyzer cost

For manufacturing dialyzer, cost will depend on your automatic assembly line and its production scale, for example, if you only manufacture 1 million dialyzers per year, of course, its cost will be higher than 10 million dialyzers production. But generally, it will be around USD2.5 ~ USD5/pcs.

Dialyzer membrane types

There are two categories: Cellulose membrane and Synthetic membrane
Cellulose membrane:
1) Regenerated cellulose
   A. Copper-modified membrane
   B. Cuprammonium membrane
2) Modified cellulose membrane
   A. Hemophan membrane
   B. Diacetic acid membrane: Nipro dialyzer, baxter dialyzer, etc.
   C. Triacetyl Cellulose: Nipro dialyzer, baxter dialyzer, etc.
Synthetic membrane:
1) Polysulfone membrane (PS): Fresenius dialyzer, Weigo dialyzer, B.Braun dialyzer, Asahi dialyzer, Haidylena dialyzer, etc.
2) Polyamide membrane (PA): Gambro dialyzer
3) Polyacrylonitrile membrane (PAN): Baxter dialyzer AN69
4) Polymethyl Methacrylate (PMMA): Toray dialyzer
5) Polyethersulfone membrane (PES): Bellco dialyzer, Nipro dialyzer, etc.

Dialyser membrane function

Dialysis membrane is a separation membrane driven by concentration difference. According to the particle size of the separated solute, the dialysis membrane is required to have suitable pores with uniform pore size. Dialyser membrane function is to separate the waste from blood and remove it out from body, remain good substance and return it back to the body.
