Beads for Hospital Beds
For certain character of patient care fluidized hospital beds have been in use for a considerable period of time, for example, during skin grafting procedures and for control of pressure induced lesions or bed sores and to support ulcerated or burned bodies of hospital bed-ridden patients
Basically, in a fluidized bed a mattress in the form of a generally rectangular bag has fluid impervious walls and bottom and a fine mesh or membrane support surface on which the patient lies.
The bag is filled with spherical glass beads that are suspended by air pressure in the bag. The air flows through the glass beads causes it to fluidize and distribute along the bottom of the top membrane, supporting the patient as it would float and provides comfort and safety
