Patient was undergoing dialysis when black smoke began to come from back of dialysis machine.
No flame or spark was seen and no heat was appreciated from hd nurse.
Patient's blood was rinsed back from the machine and he was disconnected, moved to another room and reconnected to a new dialysis machine.
No obvious physical patient harm was seen and patient had cbc drawn later to monitor for heat induced hemolysis, which was normal.
He was transferred to another room to complete his dialysis.
A total of 7 staff on the unit were exposed to smoke and went to the ed for smoke inhalation and were treated with breathing treatments.
Per review of biomed- the fluid line can sometimes leak due to weakening connectors and there is a solenoid (electrical switch) directly below the line.
The solenoid was leaked on, creating a great deal of noxious electrical smoke.
The company rep has been notified and recommendations from our biomed department have been given to the company for consideration.
