Bed handles is bed rail device that has horizontal struts that go under the mattress.
At the edge of the bed they turn upward, creating a bed handle.
Although coated with a friction coating, there is no other mechanical means to prevent the rail from moving away from the bed with pressure from the patient.
In this case, a single rail did move partly away from the bed and, a pt physically frail woman with dementia fell into the space between the vertical rail struts and the mattress, and was held in position by the horizontal struts.
She died of asphyxia.
The manufacturer has known of this event and failed to file a mandatory report, and apparently has been non compliant with post marketing surveillance in at least one other instance as well.
