FIELD OF THE INVENTION
Disclosed is a disposable curtain system, attachment therefor and method. In particular, is a disposable curtain system for use in health care facilities to maintain a clean environment.
BACKGROUND
Health care facilities, such as hospitals, nursing homes, doctor's offices, urgent care facilities, and long-term care facilities are becoming more and more concerned with infectious diseases being present. The COVID-19 pandemic is one major infectious disease that has brought attention to the public by the media to the concerns of cleanliness of health care facilities and other public spaces. In addition to COVID-19 are other infections diseases such as bacterial infection diseases like Anthrax, bacterial botulism, brucellosis, cholera, diphtheria, Lyme's disease, tuberculosis; fungal infectious diseases like aspergillosis, blastomycosis, candidiasis, cryptococcosis, histoplasmosis; parasitic infectious diseases like ascariasis, cryptosporidiosis, giardiasis, malaria, scabies; prion infectious diseases like Alper's syndrome, Creutzfeldt-Jakob disease, kuru; and viral infectious diseases like COVID-19, AIDS, chickenpox, Common Cold, Ebola, herpes, Influenza, mumps, rabies, rubella, viral meningitis, yellow fever and many more.
One location in the hospital that has a concern with infectious disease are the privacy curtains. Medical personnel will take many precautions such as washing hands, wearing gloves and wearing personal protection equipment. However, while wearing gloves they will grab the curtains with their gloved hands which may leave infectious diseases on the curtains due to contact with bodily fluids such as blood, saliva, urine, mucous, phlegm, etc. In addition, patients which are surrounded by the curtain systems will cough, sneeze or perform other bodily functions which expel airborne liquids into the air surrounding their bed or private space.
Curtain systems for hospitals are generally attached to the ceiling. The curtains systems have a track which is affixed to the ceiling. Within the track are rollers with hooks. The curtains attach to the hooks.
A difficulty with this system is that the tracks and hooks are attached to ceilings that can be from 7 to 12 feet above the ceiling. This requires maintenance personnel at the hospital to use ladders or other stools to replace the curtains.
A further difficulty is when replacing the curtain system, the roller hooks in the track many times need to be crimped causing repetitive problems with the installer having problems with muscles and tendons due to repetitive installation of the curtains on the hooks.
Another difficulty is that the most curtain systems are not easily and quickly disassembled and require personnel to remove the curtains one hook at a time.
In the past, curtain systems required keyways such as shown in U.S. Pat. No. 9,585,508.
SUMMARY
