Replacement sterile disposable parts for use with the Medi-Jector VISION® Needle-Free Insulin Injection System (sold separately). Includes 4 Needle-Free Syringes and 2 Vial Adapters with caps (supplies for 84 injections). Medi-Jector VISION® is the needle-free way to a more independent lifestyle for people who take insulin. Indications: Medi-Jector VISION® can be used with all brands of U-100 insulin in standard 10 ml vials. Needle-Free Syringes can be used for up to 21 injections and then must be replaced. Replacement Needle-Free Syringes and Vial Adapters are required for ongoing use of the Medi-Jector VISION®.

Needle-Free Syringes are available in three different versions (A, B, and C). The difference between the three versions is the size of the opening or "orifice" in the tip of the Needle-Free Syringe. A has the smallest orifice size and C has the largest.

The different Needle-Free Syringe versions allow for adjustment of the Medi-Jector VISION® system based on individual differences in skin thickness and body mass. Please review the Medi-Jector VISION® instruction manual before ordering replacement Needle-Free Syringe kits.
