ABSTRACT:
A paper handling device is provided to receive soiled paper following exposure of the paper to cover and protect a patient contact surface of a table used for medical examinations or treatments. Lateral coverage of the patient contact surface provides for usage to protect the area of the medical table corresponding to the head area of the patient, as typically used for chiropractic tables. Longitudinal coverage of the patient contact surface provides for usage to protect the entire medical table. The device provides for the repetitive usage of the medical table without requiring attending medical personnel to physically come into contact with the soiled paper following each usage. The method of measuring the paper being transferred ensure that with each respective cycle sufficient fresh paper is released from the dispensing device to provide for coverage of the patient contact surface. The prevention of contamination of the sterile source of the paper by previously exposed paper is explained in the form of unidirectional rotation of the dispensing roll. Similarly, the prevention of release of previously gathered soiled paper is explained. Housing units covering the dispensing roll as well as the take-up roll respectively protect the fresh supply and the gathered soiled paper.
