Inkjet Technology Leveraged in Home Dialysis Device

A well-known computer printer technology is in line to help dialysis patients at home. Inkjet injection technology from Hewlett Packard (HP) will merge with dialysis devices from Home Dialysis Plus (HD+) in a new dialysis system to be used at night. HP’s inkjet technology will be used within HD+’s dialysis machine proportioning system to mix the correct amount of water and concentrated dialysate, as well as the needed salt and electrolyte solution in real time, and to pump the dialysis solution into the dialyzer. Mixing the solution in real time helps to filter toxins over a longer period, HP reported. In addition, HP’s memory chip technology will be used to ensure that the correct dialysate prescription is being delivered over time so dialysis can take place while the patient is sleeping.

These technological advances are expected to afford patients a slower and more accurate nocturnal dialysis treatment that is more in tune with the body’s natural biological processes and that will dramatically reduce a patient’s post-treatment recovery time from hours to minutes.

The technology also is expected to offer a significantly smaller and more convenient option for portable and flexible care of dialysis needs at any location with access to a water source. For health-care providers, the dialysis machine should make it much easier and less expensive to train patients to perform their treatments— with a helper— at home. The cost of implementing the HD+ system is expected to be much lower than the cost of shipping prepackaged dialysate solutions.

Under the agreement, HP will license its intellectual property to HD+ in return for royalty payments. HD+ will develop, manufacture, and sell the product, which the company expects to be available in the United States and other markets by the end of 2010.
