Abstract
Provided is a system and method for a removable syringe micro pump. More specifically, the removable syringe micro pump includes a pump housing having a first end and opposite thereto an attaching end, and at least one sidewall there between, the housing having a base proximate to the first end and, the attaching end having an attacher structured and arranged to temporarily engage a syringe. A volute spring is nested within the housing and attached proximate to the base, the volute spring having a compressed first position wherein coils of the volute spring are concentrically disposed under tension such that an initial height of the volute spring is equivalent to a width of a coil, and an extended second position wherein the release of tension extends the volute spring normally away from the pump housing. The volute spring has a diameter pre-selected to pass within a barrel of the engaged syringe. The volute spring further having a distal end structured and arranged to engage a plunger seal of the engaged syringe, wherein the release of tension between the first position and the second position permits the distal end of the volute spring to move the plunger seal towards a nozzle of the syringe. An associated method of use is also provided.
