The vacuum bag cushions have been designed to comfortably position and immobilise patients in a customized way. The combination of high quality fabrics filled with polystyrene spheres ensures a highly conformal, patient-specific mould. After evacuating the air from the bags, they form a stable and patient-specific support mattress.
Vacuum bags cushions 18208, 18209 and 18210 have been designed specifically to be used on Orfit base plates (AIO Solution and Raycast types) as a patient positioning aid. Together with the thermoplastic masks from Orfit they form a highly stable and reproducible patient positioning and immobilisation system.
Other sizes are available with or without indexing laths. These indexing laths allow indexing the vacuum bags directly on the couch with the help of a 2-pin indexing bar.
The vacuum bags are completely airtight bags with a valve and a vacuum tube attached to it. The valve can easily be opened with one hand due to its small size and is permeable to X-rays and MRI. Air can be evacuated from the bag (or blown into it) by use of a vacuum pump attached to the vacuum tube. This can be done with an appropriate vacuum hose connector (supplied with the pump).
With a standard, small vacuum pump it will take 1.5 minutes to evacuate the air from the small individual head support vacuum bags (Art. No. 18208). This ensures that the vacuum is sufficient to give the vacuum bag a stable shape during at least six weeks.
