[Multiple reuse of disposable material for insulin injection without resterilization]

Of 123 type I diabetics 306 one-way syringes and canules, respectively, were repeatedly used for the insulin injection in the domestic milieu (altogether 4,157 injections). The average duration of application was 29 days (2-296), the average number of injections 51 (4-422). Of 81% of the patients no immediate cleaning was made. No local reactions appeared at the sites of injection. At the end of the use all injection materials were free from bacterial contaminations (determination of the germ number in the lumen of the syringes and canules). One-way material can repeatedly be used by one and the same diabetic for the insulin injection in the domestic milieu, observing a normal personal hygiene regimen (1 week or 30 injection in uninterrupted sequence). It is not necessary to perform an intermediate cleaning of the materials.
