Those posey straps..... we use them in the USA as well. Back when physical restraints were allowed, all restraints were called Posey because of the brand. At any rate, the ones shown, they weren't for lifting a person. They do make gait belts that you put around a person, and then walk close to them, if they are off balance, you can help them find their balance with the belt. I did see in one photo a light blue padded restraint. Those were used around the wrists or ankles to tie a person to a chair or bed. Illegal for nursing homes in VA now. I have seen them used in hospitals here as recently as 6 months ago though.
There are several items to help lift or move a patient, but I didn't see any photos of them offered.
