Syringe and Vial
This is the most commonly used, and the most economical of all the delivery devices. It consists of a vial or a small bottle and insulin syringes. The needles of the syringes are short and thin, making them less painful. Recent advancements have given rise to coated needles that further reduce the pain. The syringes have gradations to help draw the correct dosage of insulin.
In India, these insulin vials are available in two strengths 40 IU/ML and 100 IU/ML. Accordingly two types of syringes are available – red cap for 40 IU syringe with gradation up to 40 and orange cap for 100 IU syringe with gradation up to 100.
The patient must be careful in choosing the correct type of syringe for the correct dose of insulin.
