Abstract
A multiple use needle-less hypodermic injection device for individual users comprising of a light weight, pocket sized, spring powered unit, and a multiple use, low cost, easily replaceable thermoplastic injection head. The present invention targets the single-patient-self-injection applications, such as insulin users, when risks of cross contamination between different patients are not present, therefore not requiring the parts containing the medicament dose, or the parts in contact with the delivery of the medicament dose, to be necessarily disposed and replaced after each injection. The low cost plastic injection head is easily refilled by the user without dismounting from the spring powered unit, by means of an adaptor that can be attached to a standard medicament vial, or alternatively, by means of a custom made pre-filled vial which connects directly to said injection head, therefore allowing the low cost thermoplastic injection head to be refilled and used several times without necessarily having to be disposed or removed from the power unit after each injection.
