What to look for in a dialysis chair, why corrosion resistance and motor configuration decide its service life, how to plan the treatment floor, and how the same chairs serve chemotherapy, plasmapheresis and blood donation.
Chronic kidney disease is rising in Bangladesh, and dialysis capacity has not kept pace. New units are opening in private hospitals, medical college hospitals and standalone centres. The chair is the piece of furniture a dialysis patient occupies for four hours at a time, three times a week, for years. It deserves more thought than it usually receives.
A dialysis chair is not a recliner with a medical label. It has a specific clinical job:
Dialysis units are wet environments. Between spilled dialysate, saline and repeated disinfection, a chair frame takes chemical punishment that ordinary ward furniture never sees. This is why some manufacturers build the underframe from composite plastic that is self-supporting without steel components, removing the corrosion risk at its source rather than coating over it. If you are comparing chairs on price alone, ask what the frame is made of and how it behaves after five years of chlorine-based disinfection.
The number of independent motors determines how precisely a patient can be positioned. A four-motor chair drives backrest, seat tilt, legrest and seat height separately, which allows a clinically correct position rather than a compromise between two linked movements. Chairs in this class typically carry a maximum patient load in the region of 200 kg, which matters more than it once did.
| Feature | What it does | Worth it when |
|---|---|---|
| Integrated patient scale | Weighs the patient in the chair | Fluid removal is calculated from pre and post-dialysis weight. Removes transfers and speeds up turnaround. |
| Battery operation | Chair works during a power cut | Bangladesh load-shedding is a live risk. A patient mid-session cannot wait for the generator to catch. |
| Trendelenburg | Rapid head-down tilt | Always. Intra-dialytic hypotension is routine, not exceptional. |
| Transport variant | Chair doubles as an indoor patient transport chair | Units where patients arrive by wheelchair and transfer twice per visit. |
The same treatment chair platform generally serves dialysis, chemotherapy, plasma collection, plasmapheresis, infusion therapy, blood donation, transcranial magnetic stimulation and one-day surgery recovery. For a hospital this is a procurement advantage: standardising on one chair family across departments simplifies spares, training and service, and usually improves the commercial terms. Specify the variants you need rather than treating each department as a separate purchase.
Chair choice and floor layout are linked. A few practical points that are easier to fix on a drawing than after commissioning:
For imported treatment chairs, ask for EU Medical Device Regulation compliance documentation and the manufacturer's quality management certification. For government projects, the supplier should provide manufacturer authorisation, compliant technical specifications and catalogues suitable for e-GP tender submission. Vvon supplies all of these as part of a tender package.
