HM-280 function
Be applicable of hemodialysis treatment, hemoperfusion, Plasma Exchange, Pure ultrafiltration project.
Touch screen was equipped and it can show Naand UF profiles; In addition, the functions ie. Backup power
Supply, Kt/V, HC adjustment, single needle, acetate treatment, pyrogen filter port and net connection ect. Are optional.

Clinical Application
1. Hemodialysis Therapy: Mainly suitable for all kinds of acute and chronic kidney failure patient.
2. Pure ultrafiltration Therapy: Mainly suitable for patients with excessive water stored in the body due to acute, chronic kidney failure or incomplete heart function.
3. Hemoperfusion Therapy: Mainly applies in the acute drug poisoning. Patients whose condition still continue worsening after some rescue measures such as
Gastric lavage, catharsis, infusion and forced diuresis should consider this therapy, especially those accompanied by the brain function
Barrier or stuper, liver and kidney function barrier, old patients whose tissue protein is highly combined with medicine and metabolite(such as organic phosphorus agricultural chemicals), and who takes medicine oversized which had achieved the toxicant lethal dose
Density or exceed 30% of their own elimination ability are also suitable for hemoperfusion therapy.
4. Plasma exchange Therapy: Mainly suitable for the immunity diseases; Acute nephritis, lupous nephritis, frequent myeloma nephrosis, serious myasthenia, acute
Liver function failure, thyroid gland crisis, ethnic hypercholesterolemia, HVS, acute-chronic rejection prior to/after kidney transplant, transplant recurs nephritis, acute demyelination multimental illness(Grimm Bari syndrome), selfimmunity hemolytic anemia, selfimmunity blood platelet reduced purpura, hemolytic uremia syndrome,
The cold globin proteinemia, yellow hepatatrophia.

5. Na+and UF profiling:
Be applicable for reducing the cases during dialysis treatment such as low/high pressure, muscle convulsion,
Headache, nausea, vomit ect.
6. Kt/V function:
The sufficiency of dialysis can be reflected by Kt/V. (Standard)
7. HCO3 adjustment function:
Be applicable for sericous acid toxicosis patient.
Be capable to calibrate the acid toxicosis status according to patient's state of illness. (Standard)
8. Backup power-supply:
It can last for 15-30 minutes after power cut off.
