Ultrasonic cleaning device

Abstract

The ultrasonic cleaning device includes an ultrasonic radiation insulated container for holding a cleaning detergent. A first perforated basket for holding medical or dental tools is carried within the container. The open end of the container is closed by a cover having a peripherally attached rubber gasket and having its bottom side molded with waffle-like indentations for reflecting and/or absorbing ultrasonic radiation. The container and first perforated basket are sized such that one or more baskets can be carried on top of the first basket or, in the alternative, can be fitted with a stainless steel template having a pair of openings for receiving a glass container. The ultrasonic cleaning device is adapted with an automatic timer and a voltage regulator for varying the voltage input which, in turn, varies the ultrasonic frequency introduced into the cleaning detergent. The device is designed to produce a frequency of about one megacycle and can complete the cleaning cycle within 5-15 minutes. The use of an ultrasonic insulated container and cover prevents or minimizes the emission of ultrasonic radiation into an area immediately outside of the container.
