3D printing drastically reduces development costs of blood recycling machine


During surgery, patients’ blood is often “shed.” Such blood could be returned to the body, so long as it has been properly processed to ensure it’s not tainted. The Brightwave Hemosep autotransfusion machine can do this – and its prototyping costs are cut by 96 percent via 3D printing.

Gizmag featured the Hemosep when it had been found in 2012. The device works by gathering the blood shed during surgery and concentrating it using a mechanical agitator. Once the blood was prepared, it is received by the patient by way of an intravenous transfusion.

There certainly are numerous advantages to recycling a patient’s own blood during operation. In addition to reducing the importance of donor blood, which can regularly be in short supply, it minimizes the threat of complications due to possible adverse reactions to donor blood, including contamination or immunosuppression. It is considerably safer for children, who face greater dangers than adults during such procedures and also needs simpler, cheaper equipment.

In a blog post, 3D printer maker Stratasys recently explained how Brightwake continues to be able to radically reduce the expenses associated with producing images for the ongoing development of the Hemosep.
