Abstract

621,208. Continuous injection syringe apparatus. BOWIE, J. H. Feb. 20, 1946, No. 5368 [Class 81(ii)] [Also in Group XXXVII] An injection syringe apparatus, adapted to be secured to a patient, is provided with means for mechanically advancing the piston of the syringe at a slow and constant speed so that liquid may be continuously injected into the patient over a prolonged period, e.g. 24 hours. The .apparatus comprises a plate 1 to which is detachably secured a base plate 3 on which is mounted a syringe 4 by means of clamps 5. An enlarged head 8 of the piston rod rests in a saddle 9 which is adapted to be moved longitudinally by rotation of a lead screw 11 detachably connected to a flexible cable 14 driven by a suitable form of mechanism (see Group XXXVII), which may drive several syringe devices simultaneously. The forward end of the syringe is provided with a two-way cock 17 to which an injecton needle is resiliently connected. Specification 621,283 is referred to.
