Designing Heaters for Hemodialysis Machines

Hemodialysis is the most common therapy in dialysis technology. Hemodialysis is done with a computerized machine that is connected to the patient with a needle or permanent catheter  Controlling the temperature of the dialysate and the blood is critical to the patient.

Heatron has probably designed several million heating elements for hemodialysis and peritoneal dialysis machine. Essentially more than any other manufacturer.

What are the things to watch for when designing hemodialysis machines?

  • Use of the proper metals in the heater so that breakdown of the metals doesn’t leach into the dialysate or blood stream.
  • Maintaining temperature within just a few degrees.
  • Safety shutdown to prevent life threatening thermal runaway. In fact, be sure to ask Heatron engineers about their proprietary safety shutdown.
  • FDA approval
  • Faster to market by working with engineers who know how to design safely working heaters, and work through the FDA approval system faster

Working with Heatron’s engineers results in faster-to-marketwith  four big advantages

  • Faster to market
  • Less cost to market
  • Safety for patients
  • ISO quality system

The dialysis machine carries the blood out of the patient’s body (about two cups at a time), filters the blood through a dialyzer which is a mechanical version of a kidney. It contains a chemical solution (dialysate) that pulls toxins, extra salts and extra fluids from the blood, and return the filtered blood to the patient’s body.

A heating element for the hemodialysis machine is used to control the temperature of the dialysate very closely around body temperature to prevent shock to the patient, and is also used between dialysis treatments to sterilize, or clean the machine.  One of the biggest issues is safety to prevent thermal runaway (too much heat), or even too little heat.

Heatron has developed a unique safety feature for the hemodialysis machines using their heating elements.

Heatron has probably manufactured more heaters, and heating elements for medical equipment that most any other company. Heaters used in hemodialysis machines, peritoneal dialysis machines, blood warmers in open heart surgery, heating elements in CPAP and BiPap humidifiers, DNA sequencers, heaters to warm fluids before injections, and many, many other medical devices.

Heatron’s strength for it’s medical equipment manufacturing partners is in its experience with faster design time, and FDA approval which can accelerate your equipment approval times and lower costs.

Call a Heatron engineer to discuss how to get your hemodialysis, or peritoneal deialysis design to market faster and less expensively.
