may be made from a vinyl or a suitable rubber compound that provides the flexibility required to provide for the bulb to be squeezed or compressed to draw in fluid when released and to discharge such fluid when it is again compressed the valve 12 also may be made from vinyl or rubber in order to provide the flexibility necessary for operation of a flap valve incorporated as an integral part of the valve the stem or nozzle 13 may be formed from polypropylene or polyethylene however if it is desired that the nozzle be transparent it can be made of styrene and when it may be desirable to make the nozzle opaque it can be formed of an acrylic the bulb 11 may be generally typical of syringe bulbs of this type and is sufficiently flexible to admit of its being compressed by hand squeezing in the operations of both filling the syringe with fluid and in the discharge thereof when using the syringe to flush out an ear the bulb is generally spherical but has a concavity 14 on the bottom end which provides an area for standing the syringe upright when not being used the top of the bulb as viewed in the drawings has an opening 15 into which both the control valve 12 and the inner end of the stem or nozzle 13 are received the bulb has an upwardly projecting portion 16 in which the opening 15 is formed and in which the stem 13 is mounted the opening 15 are formed in the projection 16 has an upper cylindrical inner surface 17 and immediately beneath this cylindrical entrance an inwardly and downwardly tapering surface 18 overlies a downwardly facing shoulder 19 which has a generally.
