ABSTRACT:
Apparatus and method for cleaning and disinfecting medical instruments such as laryngoscope blades are provided. The apparatus includes a container body having exterior walls and interior partitions defining a plurality of chambers defining a soaking area, a scrubbing area, and a pair of rinsing chambers. The container, preferably constructed of plastic, is also formed with integrally hinged covers for the respective chambers. Flexible brush means are provided within the scrubbing chamber. A pair of injection ports are provided in the soaking area of one chamber for receiving a pair of syringes for injecting buffer and activating components of a cleaning and disinfecting solution into the soaking area. A partition extending between the soaking area and the scrubbing area of the one chamber permits the solution to pass freely therebetween. An additional cover is provided to shield the syringes. In a preferred process, a medical instrument is cleaned by the steps of at least partially filling said soaking, scrubbing and rinsing areas with water; injecting the cleaning and disinfecting solution into the soaking area; scrubbing the instrument in said scrubbing area; inserting the instrument into the soaking area for a prescribed period of time; removing said instrument from the soaking area and thereafter inserting it into a first rinsing area; and removing the instrument from the first rinsing area and inserting it in a second rinsing area.
