We got a few of these, and they seemed okay, but now Supplies have decided to go with Proact. I haven't witnessed any problems with the Flexiport, but they haven't been in long.
Lots of manufacturers are producing cuffs to cope with being washed, but I don't see much evidence that staff wash them. Thankfully, we have always had stock so that if we see a gungy cuff we can change it.
The Proact ones are interesting. We didn't see them (at this hospital, they probably did at our sister hospital) before Supplies made this choice, and they only have one tube. It will be interesting to see how well they can be adapted to fit things with two tubes, e.g. Critikon Dinamap style physiological monitors.

Disposable would reduce the risk of contamination etc, except that it costs so much and I think that it is wasteful of resources. I would love to see a way of recycling things more often more safely. We throw away too much as a society anyway.
