Abstract: A bulb syringe has a hollow spheroidal bulb which is split into two separate hemispheroidal portions transaxially defining an upper portion and a lower portion. The separate hemispheroidal portions are joined at a transaxial juncture of the upper and lower portions, and are able to be separated for disinfecting and later rejoined. One of the upper and lower portions extends into an elongated tubular spout terminating at an opening which is in communication with an interior volume of the spheroidal bulb. The tip of the spout is able to be positioned within the nostrils of an infant or small child. The two portions may be joined by molded-in mechanical threads or by an external circumferential strip with barbs that penetrate overlapping walls of the bulb at the joint between upper and lower portions but does not fully puncture the bulb.

Abstract: A U-shaped mouthpiece joined with a delivery tube engaged at one of its ends and with a handle at an opposing end. The mouthpiece has an outer wall enclosing a hollow space, the outer wall configured as either one or two wells, each sized for receiving plural teeth. A plurality of apertures in the outer wall are positioned and extensive for directing a fluid within the hollow space into the well as jet steams. A plurality of bristles are mounted on the outer wall within the well in positions for fluid impingement by the fluid exiting the apertures. A fluid pump pressurizes the mouthpiece to enable the jet streams to impinge on the bristles so as to scour the teeth.
