The latest medical bed standard IEC60601-2-52 requires medical bed frames, that are equipped with bed rails to provide a depth of 22cm between the top of the bed rail and the top surface of the uncompressed mattress. This is to provide sufficient height to prevent a patient from falling out of bed. The use of deep cell air mattresses means that the depth of bed rail is often less than 22cm, which means that there is an increased risk of someone falling out of bed. This also calls into question the CE status of the bed and insurance relating to it.
There appear to be two solutions.
The first is to use a suitable active mattress of circa 13cm, as this will fit most if not all medical bed frames in terms of providing 22cm between the mattress and top of the bed rail. Most of the Squirrel Medical range of active mattresses are 13cm depth.
The second option is to artificially increase the height of the bed rail, through the use of a bed rail height extension. This is questionable on so many fronts as the extension is in effect a modification of the medical bed. Its increased height means that there is further to fall and thus a greater risk of injuries. Bed rail height extensions are difficult and time consuming to attach and they are expensive.
Squirrel Medical™ suggest that before you consider using a bed rail height extension, that you consider using a patented Squirrel Diamond or Dormir active mattress as both provide a depth of 22cm when used on most medical bed frames.
