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.
