Abstract: The present invention involves a sterilizable syringe allows for reduction in needlestick injuries using conventional sterile needles. The syringe allows for direct access to and the safe removal and disposal of needles. The device consists of a sterilizable, reusable hypodermic syringe to which a disposable needle is attached, and employs carpules containing injectable medication, viewable and either manually or automatically aspirating. Some embodiments have a protective sliding mechanism consisting of an open frame bearing one or more protective collars, one at the furthermost end of the frame and an optional second one at a more proximal position. The protective mechanism may be extended to protect an exposed needle tip and retracted during an injection. With the protective mechanism extended, the needle mounting hub is exposed to allow for its exchange or removal and safe disposal.

Abstract: This invention relates to table top steam sterilizers, wherein a novel method of heat conservation within the sterilizer, using fixed vacuum chamber walls, is described. As well, the temperature of the sterilizer is more accurately regulated and stabilized by power application to a single heating coil with the use of a proportional controller, and by use of temperature, pressure and humidity sensors. The method also relates to a post-sterilization moisture evacuation process using a venturi. When this method is employed, the time required for the sterilization process is reduced.

Abstract: A non-toxic solution to be used in the place of distilled or de-ionized water in autoclave sterilizers is disclosed. The solution renders the instruments placed in such sterilizers free of rust, spotting, and hastens the drying time of such instruments.
