American wearable artificial kidney how no news

The reason there's no news on the US wearable artificial kidney is because it hasn't reached the level of technology for implantation. The wearable artificial kidney passed the FDA's Phase I clinical trial in 2015, when a total of **** 7 patients were tested, and 5 patients used it to successfully complete 24 hours of dialysis, dialysis to achieve a creatinine clearance of about 15 ml/min, in other words, to return kidney function to the level of Chronic Kidney Disease stage 4. The trial was terminated early for reasons of clotting and air bubbles in the dialysis cycle in the other 2 patients. The wearable artificial kidney weighed 4.5 kilograms at the time, and it was still not convenient enough to pin on the waist.
