Sterile drape for two tiered hospital instrument table
View Patent ↗The present disclosure describes a draping system for a two-tiered hospital instrument back table can be used to quickly and conveniently create a sterile field. The system has a drape that is a single piece of material, desirably a film that may be clear. The single piece of material has other material attached to it on its upper side or surface in areas that generally coincide with the two upper surfaces of the table when the drape is installed on the table, and that has a lower coefficient of friction than the single piece of material. The drape may be held in place with a continuous or discontinuous band that encircles the upper tier or the upper tier support posts.
1. A draping system for a surgical table having an upper tier and a lower tier, each tier having an upper surface, a lower surface, and a front and rear, the table having support posts between the upper tier and the lower tier to support the upper tier, the system comprising: a drape capable of being placed on the upper tier and the lower tier of said surgical table, where said drape is made from a single piece of first material having an upper and lower side, with an area of a second material having a higher coefficient of friction than said first material arranged on the upper side of said first material in an area that at least generally coincides with the upper surface of the lower tier of the table when said drape is installed on said table, and a band adapted to hold said drape in place at the rear of the upper tier of the table when said drape is installed on said table, wherein the band has an end to end dimension at least as long as a longest horizontal dimension of said drape, wherein the band is a continuous band or a discontinuous band, wherein the continuous band is a continuous loop that is configured to completely encircle both the upper surface and lower surface of the upper tier of the table and the discontinuous band is a single band with two ends configured to releasably attach at and partially encircle the upper surface and completely encircle the lower surface of the upper tier of the table.
2. The draping system of claim 1 , the drape further comprising a third material having a higher coefficient of friction than said first material arranged on a portion of the upper side of the first material in an area that is adapted to generally coincide with a portion of the upper surface of the upper tier of the table when said drape is installed on said table.
3. The draping system of claim 2 , the drape further comprising a fourth material having a high coefficient of friction on a portion of the lower side of said drape in an area that is adapted to generally coincide with a portion of the upper surface of the lower tier of the table.
4. The draping system of claim 3 , the drape further comprising a fifth material having a high coefficient of friction on a portion of the lower side of said drape in an area that is adapted to generally coincide with at least a portion of the upper surface of the upper tier of the table.
5. The draping system of claim 3 wherein said fourth material, fifth material, or a combination thereof on said lower side of said drape is a hot melt adhesive.
6. The draping system of claim 1 , wherein said drape comprises a film.
7. The draping system of claim 6 , wherein said film is clear.
8. The draping system of claim 1 , wherein said drape is free of a fastener in a center of the drape to attach the drape to the table.
9. The draping system of claim 1 wherein said continuous band is elastic.
10. The draping system of claim 1 wherein said band is said discontinuous band.
11. The draping system of claim 1 wherein said band is said discontinuous band and attaches to itself.
12. The draping system of claim 1 wherein said band is said discontinuous band and attaches to a third material.
13. The draping system of claim 1 , wherein the band is said discontinuous band, and further comprises comprising a first clamp and a second clamp, wherein the first clamp is adapted to hold the band in place at a first end of said table and the second clamp is adapted to hold the band in place at a second end of said table.
14. The draping system of claim 1 wherein said drape is adapted to be tapered between the upper and lower tiers of the table.
15. A draping system for a surgical table having an upper tier and a lower tier, the upper tier supported by support posts, each tier having an upper surface, a lower surface, and a front and rear, comprising: a drape capable of being placed on the upper tier and the lower tier of said surgical table, where said drape is made from a single piece of impervious film having an upper and lower side, with an area of a wettable nonwoven fabric having a higher coefficient of friction than said film arranged on the upper side of the film in an area that generally coincides with the upper surface of the lower tier of the table when said drape is installed on said table, and a continuous or discontinuous band adapted to hold said drape in place at the rear of the upper tier of the table when said drape is installed on said table, wherein the continuous or discontinuous band has an end to end dimension at least as long as a longest horizontal dimension of said drape, wherein the continuous band is a continuous loop, that is configured to completely encircle both the upper surface and lower surface of the upper tier of the table and the discontinuous band is a single band with two ends configured to releasably attach at and partially encircle the upper surface of the upper tier of the table and completely encircles the lower surface of the upper tier of the table.
16. The draping system of claim 15 further comprising a material having a high coefficient of friction on a portion of the lower side of said drape in an area that is adapted to generally coincide with a portion of the upper surface of the lower tier of the table.
