Abstract: A drug injection device (or what some might prefer to call a "drug injection site") comprises a doubled wall, doughnut-shaped cylinder adapted to be inserted into an intravenous delivery tube. Preferably it is made of a pair of identically shaped elements having an outer end an inner circular wall, both of which, when the two elements are placed together in opposed relationship, form continuous walls of a doughnut or O-ring shape. The interior of the doughnut is filled with a soft surgical grade rubber which, when under compression, permits ready insertion of a hypodermic needle therethrough but which, when the needle is withdrawn, is self-sealing. A plurality of radially aligned apertures, or windows, are provided in the inner and outer walls, so that the hypodermic needle can be inserted through the outer wall, through the rubber sealing element and then through the aligned window in the inner wall. Preferably, the windows are three in number, equally spaced around the circumference of the device, so that when a needle is inserted through the respective windows and the rubber sealing element, it will be stopped by an opposing wall of the inner solid surface of the inner wall of the device.
