Abstract

An improved method for cleaning and sterilizing medical and dental instruments ( 16 ) employs the use of a banding device ( 10 ) to segregate and hold together medical or dental instruments ( 16 ) after use in a particular procedure. The banded instruments ( 16 ) are then cleaned and sterilized. This method essentially eliminates the time and effort formerly required when unsegregated instruments were mixed with other instruments for cleaning and sterilization and then stored according to the particular procedure for which they are intended and/or according to the intended particular user thereof.

Claims (18)

1. In a method for cleaning and sterilizing medical and dental instruments, which method includes the steps of

collecting such instruments used in a plurality of medical or dental procedures after use thereof in such plurality of procedures,

cleaning such collected instruments,

sterilizing such cleaned instruments, and

segregating and sorting such sterilized instruments into groups according to the particular surgical or medical procedure for which they are intended, and

storing such groups of sterilized instruments until the next use thereof

the improved method comprising the steps in sequence of

(a) initially banding each group of such instruments together after use thereof in a particular medical or dental procedure, such that each such banded group includes only the instruments used for that particular procedure;

(b) collecting a plurality of such banded groups of instruments;

(c) cleaning and sterilizing such plurality of banded groups of instruments; and

(d) storing such cleaned, sterilized banded groups until the next use thereof.

2. The method of claim 1 wherein the material from which the bands fabricated is selected to withstand the chemical and temperature conditions of said cleaning and sterilizing step.

3. The method of claim 1 wherein the bands are color coded.

4. The method of claim 1 wherein the bands are fabricated from an elastomeric material capable of stretching at least 100% and capable of withstanding temperatures in the range 212-450 degrees Fahrenheit, and said bands comprise:
