The Tautmann Transfer Trolley is designed to transport patients hygienicaly from carriage to carriage, room to room and area to area seamlessly without lifting the patient off their mattress. The system consists of two under-carriages and one over-carriage that supports the mattress and the patient. When the two under-carriages connect vioa our patented locking mechanism, the patient is free to slide from one carriage to the pther effortlessly within seconds. In the meantime, the patient is undisturbed and the clean under-carriage stays clean in it’s clean environment.
