Abstract

739,753. Hypodermic syringes. VOORHORST, J. Jan. 16, 1954, No. 1361/54. Class 81 (2). An orifice is formed in a needle mount which may be opened by relative turning of the mount and syringe nipple on which it is placed, so as to vent the bore of the nipple to atmosphere. Such venting ensures that there shall be no sucking back of the contents of a used needle as this is withdrawn from the syringe. In its simplest form a drilling 4 communicates with the bore 3 of the nipple 1. The needle mount is provided with a longitudinal slot 7, communicating with its axial bore, so that, by rotation, this slot may be aligned with the hole 4 before the needle is removed. The hole 4 and the slot 7 may be replaced by axial surface grooves if desired. In a modification the mount is screwed on to the syringe nipple and has a lateral drilling leading to an internal cavity. When the mount is screwed tightly on to the nipple the end of the latter is pressed tightly against the further end of the cavity and is sealed except for its communication with the needle. Immediately the mount is unscrewed this seal is broken and the nipple is vented to atmosphere through the cavity and lateral aperture.
