Abstract: A double-barreled syringe is provided which includes a mixing tip which is detachable after the tip is locked to the syringe body, so that the tip may be replaced by a locking cap. Locking occurs when a neck extending from the body between two shoulders is inserted into a bore in the tip (or, alternatively, the cap) and the tip is rotated so that two symmetrically opposed tabs attached to the tip are each received within a recess determined by a shoulder and a locking rib attached to the shoulder, and two diametrically opposed detents extending from the neck are each received within a recess in the bore surface.

Abstract: A dual action tongue scraper provides either a hard scrape or a soft scrape of the tongue, as desired. A hard scraping surface and a soft scraping surface are formed along at least one of the edges of a strip of flexible material. A user bends the strip of flexible material such that generally only one of the hard scraping surface and the soft scraping surface contacts the user's tongue at a given time during scraping.

Abstract: A tongue scraper having a convex-shaped edge and a linear edge. The convex-shaped edge conforms to the lateral concavity of the tongue. The linear edge conforms to planar areas of the tongue. Tight gripping of the scraper is facilitated by a hole at each end intended to be pinched between the thumb and finger. In a first embodiment the scraper includes serrations on the convex and linear edges. In a second embodiment the convex and linear edges are smooth.
