This replacement air bladder cell is only meant for use with the Drive Medical 14027 Med-Aire Alternating Pressure Mattress Replacement System. The air bladder cell is the part of the pressure redistribution mattress that fills up with air. There are 2 types of bladder cells: one with laser holes and the other without - both are necessary for the alternating pressure mattress. The bladder cells with the laser holes make up the middle 9 cells of the alternating pressure mattress, and they allow a little air to be released over time to alternate the pressure of the mattress. The bladder cells without the laser holes make up the other 11 cells of the alternating pressure mattress, and they do not release a small amount of air like the cells with laser holes.
