This instrument was developed to help patients who were
apprehensive to self inject. Many were diabetics who
required several daily injections.
The apparatus was loaded with a 2.0ml. “Luerlock” syringe connected to a 1.25cm. needle. It contained an appropriate dose of insulin. On pressing the trigger the needle was propelled into the subcutaneous tissue and the insulin injected. The maker claimed that the procedure was almost painless.
It was invented, and designed by Mr. D.T. Lewis of Port Lincoln, and manufactured by Ashton & Co. Ltd. in Hilton SA in the latter part of the 20th. century. It is seldom used today as there are problems with sterility.
