Abstract

143,084. Luswergh, E. June 28, 1919. Syringes.-A hypodermic syringe is constructed so that the penetration of the needle, the injection of the fluid, and the withdrawal of the needle are performed automatically. The apparatus comprises three telescopic cylinders A, C, F with springs M<1>, M interposed as shown. The cylinders are held in the closed position, Fig. 3, by means of a tooth on a lever G projecting through an opening L<1> in the cylinder F and an underlying opening L<2> in the cylinder C. The cylinder F is then drawn downwards by momentarily releasing the tooth on the lever G and allowing it to snap through another hole in the cylinder C and project above the enlarged lower end of the cylinder A, which, on being drawn upwards, causes the tooth to snap over and maintain it in the drawn-out position. The filled syringe is then secured in the cylinder A by a screwed ring H. A rack R is then drawn out of its sheath Q until a finger b at its upper end can be rotated so as to rest upon a button a at the top of the piston-rod t. The rack, while being drawn out, rotates a spur-wheel T which winds up a spring U held in a drum V. A pawl Y acting on a ratchet-wheel X secured to the wheel T prevents unwinding. A thimble Z sliding on the cylinder F regulates the depth of penetration. On applying the apparatus to the part where the injection is to be made and pressing on the lever G, the spring M<1> is released and carries down the part A, which, by means of the attached lugs B<1>, B<2>, carries down the driving- mechanism and causes the needle to penetrate as far as allowed by the thimble Z. As the part A moves down, the projecting part of the cylinder C lifts the pawl Y and releases the spring U, which drives the rack R and, by means of the finger b, depresses the piston and expels the extents of the syringe. At the limit of its down. ward movement, the rack meets the tails e of a pawl E, which releases the spring M, and thus raises the cylinders C, A and thereby withdraws the needle.
