ABSTRACT:
A long life vacuum for use primarily by a dental assistant for evacuating debris from the mouth of a patient during dental operations. The instrument takes the form of an open-ended tube having a quick disconnect coupler at one end to enable the tube to be coupled to a vacuum line. The other end of the tube is intended to be inserted into the mouth of the patient. The instrument is formed entirely of plastic so that it may be conveniently sterilized in a high temperature autoclave. Specifically, plastic seals are used instead of O-rings since O-rings are incapable of withstanding high temperatures and/or chemicals used during the sterilizing operations. In addition, there are no metal parts which would be subject to corrosive attach by the bonding materals currently used by many dentists. The instrument includes a valve which is operated by the dental assistant, and which is sealed to the tube by integral plastic seals.
