A transfer aid for application of lifting sling and positioning Immedia SlingOn is primarily designed for easy application of a hoist sling in bed without the need for logrolling or moving the user. SlingOn consists of two separate ultra low friction nylon slide sheets held together by snap buttons in the corners and it has handles along the sides. SlingOn is an ideal aid for users that needs frequent hoisting, heavy users, or users that should not be logrolled for application of a sling. In addition it can be used for all positioning in bed. SlingOn is placed under the user using a simple folding technique, whether it is for the application of sling or for positioning. The hoist sling is then inserted between the two layers of SlingOn. The ultra low friction facilitates sliding the sling in place underneath the user, and adjustment if necessary. When the hoist sling is in place, remove the top part of SlingOn. Note: The user is always lifted in the sling, never in SlingOn. Always remove the top part of SlingOn before hoisting.
