Abstract: 968,303. Surgical injection appliances. E. A. BROWN. Sept. 27, 1962 [Nov. 8, 1961], No. 36701/62. Heading A5R. A prepacked charge for a hypodermic syringe comprises two immiscible substances of different colours. By rotating the injection needle through 360 degrees during injection of the first substance, this is received into the body in the form of a spherical globule, and the second substance is then placed within this globule. By this means the second substance only reaches the tissues after the first has been absorbed, or its rate of absorption is slowed down. The difference in colour provides a clear line of separation which indicates to the user when the first substance has been completely injected. A syringe suitable for use in the procedure comprises a barrel 5, rotatably secured to the finger ring and associated with a plunger 1 which has a helical groove 3 for co-operation with a pin 4 in the barrel. As the plunger is pressed forward, during the injection, it is held against rotation by the user's thumb and the barrel 5 and needle 6 are rotated.
