Machine is manufactured in 2017 with older blood pump roller. I understand new machines have different blood pump. Can the spring be reinstalled? I was told no by my coworkers that they can’t and have been buying and replacing blood pump rollers with new ones as they break after getting yanked off the blood pump shaft and hitting the floor and knocking the spring out. They aren’t cheap. Just want to know what others are doing.

Your coworkers are correct. The roller assembly body breaks and can't be repaired.
Wait till you see the new blood pumps. The rollers appear to be more robust but the door/covers are crap and cost as much as the rollers.

I have found that if you have the right tool, the roller isn't cracked, and you're both careful and lucky you can sometimes get the springs back in. But it's a 50/50 and is more short than long term effective.
If you have Rollers coming off the post, likely the Latches need replaced. That button piece wears over time and you can buy them directly from Braun. All you need is a T6 to remove the screws. It helps keep them from falling when lines are removed. Price is only a few dollars per latch compared to full price of roller

Stop yanking the lines off the roller. If the staff does it properly - 99.5% of the time the roller won't leave the chat.

<carl> Staff should NOT be pulling on the tubing to remove it from the BP assembly. In fact, our clinical specifically teaches: using the left hand to hold the tubing on the left bottom of the BP assembly, guide the tubing out of the assembly while rotating the roller CW with the right hand until the tubing is free of the BP assembly. Pulling the tubing puts lateral stress on the roller, causing the pin bearings to dig into their holding material (see brown dust?) and the latch to compress, allowing the roller to move outward on the shaft (pop off).
NOTE: a knowledgeable person would think that if an action they were doing caused a component to pop off of a machine, that maybe that action was not proper.

I have passed this onto our FA for reference. She’s aware that we have replaced 3 blood pump rollers in her clinic in the last month from staff yanking the blood lines out of the blood pump. Most of the time I find the broken roller with spring on my desk and the blood pump door on a spare machine open and the roller missing. No one will admit they did it because they know better |

I took over a different facility in my company and one month had 6 roller replacements in a month. 4 of them were replaced for rusting up so badly they couldn't spin properly during treatment or even be turned by hand without stalling. Had to find a good cleaning product to remove the red stains caused by the dust being spread. |
