Although the above equipment draping concepts have 10 Safe Lifting and Movement of Nursing Home Residents , been disclosed , none of them apply to the specific concerns February 2006 . ) Thus , there is a need to create inventions regarding patient handling equipment such as patient hoists , that will lower the number of healthcare worker injuries lifts and the like . Rather , much of the equipment drape caused by heavy lifting and to provide for placement of systems merely comprise sheets of material that can be used otherwise unsterilizable equipment in the operating room to wrap around operating room equipment but cannot easily 15 under sterile conditions . accommodate support structures built into patient lifting Surgical slings for lifting or supporting a patient are devices . similar to the surgical drape in that prior sling devices were

Concerning safe patient handling issues as it relates to not typically made sterile in and of themselves . Rather , sterility and the sterile environment of the operating room , sterile drape material was used between the lifting / support often times there is a need to manipulate and position a 20 sling and the patient if a lifting device is used at all . U . S .

If 25 field in the operating room . The apparatus is designed to the patient ' s body or limb must be repositioned , the sterile hang into the sterile field thus allowing its easy entry and draping is disturbed by the need to manipulate the patient exit from the surgery area . Thus , certain devices for lifting against the non - sterile sling . Further , presently doctors and patient body parts have been disclosed for uses within a operating room staff must themselves physically lift , hold , sterile environment , but there is no conception disclosed for and rotate patients and / or patient body parts , such as arms 30 a sterile patient body support sling and / or hoist system and legs , all of which weigh substantial poundage . Such designed for use in patient handling within the sterile patient body manipulation is often problematic in numerous environment . Moreover , the present hoisting system com ways with respect to safe patient handling including danger ponents such as crossbars to which slings are attached are to patient from accidentally being dropped , and subsequent lacking in design in that due to sling hanging points manu loss of sterile environment due to a patient drape , or part 35 factured at the ends of the bar , and the methodology and thereof , touching non - sterile and non - prepped slings or other need to attach sling loops at those limited locations , causes operating room equipment . Under such conditions , not only the sling to bunch up and in turn cause undesired pressure is the patient at risk of mishandling , the operating room staff and compression on patient body parts . is also at risk in the form of body injury from lifting and As will be disclosed below , notwithstanding the numerous supporting patient body and body part weight and often at 40 prior surgical drape configurations , there remains a long felt angles unfit for maintenance of good back muscle health . need in the art of safe patient handling , particularly in sterile Thus , a focus on draping the patient as opposed to draping operating room environments , for drape systems , slings and operating room patient handling equipment has set up work improved lifting device components such as crossbars that environment conditions that can result in occupational inju - will provide the ability to use , within the operating room and ries to hospital operating room staff . 45 under sterile conditions , bulky equipment and machinery ,
