Universal sterile drape and support system for in-operating-room safe patient handling equipment
View Patent ↗Described are surgical drapes and system with universal application to heavy equipment useful in operating room environments. Surgical drape systems of the invention are particularly capable of covering patient support machinery such as hoists, lifts, and slings, whether the equipment is mobile or stationary, or configured as a floor-based or as an overhead support/lifting system. The drapes of the current invention provide for protecting the equipment from exposure to surgical biohazard waste e.g.; blood or body fluids, as well as providing the ability to use equipment that is otherwise not presently allowed to enter into an operating room because of the impossibility to render such equipment sterile. The drapes further allow for the holding, lifting and positioning of the patient whole body or limbs while maintaining sterility during prepping and surgical procedures. Also included are support slings for use with the drapes.
1. In combination with a patient hoist system presenting a support framework for a depending cross bar and a sling suspended from the cross bar, the sling supporting a patient body portion, a sterile encapsulation apparatus comprising:
a drape presenting a flexible body spanning first and second ends;
an opening at said first drape end adapted to slide over the cross bar in extension away from said second drape end to cover the cross bar and support framework of the hoisting apparatus, said second end of said drape adjacent the cross bar;
a first reinforcing web at said second end of said drape, said first reinforcing web adjacent the cross bar upon said drape covering the cross bar and support framework of the hoist system;
a second reinforcing web on the sling for contacting said first reinforcing web of said drape upon the suspension of the support sling from the cross bar, said contact of said first and second reinforcing webs diminishing stresses acting therebetween upon the sling supporting the patient body portion.
2. The apparatus as claimed in claim 1 wherein the sling presents at least one loop at respective ends of the sling, said second reinforcing web along said at least one loop.
3. The apparatus as claimed in claim 1 wherein the support framework of the patient hoist system includes a ground support base, said first end of said drape surrounding the base upon said drape covering the framework and cross bar.
4. The apparatus as claimed in claim 1 wherein the support framework of the patient hoist system depends from an overhead support, said first end of said drape surrounding the depending framework and cross bar.
