System and method for a syringe micro pump with volute spring
First Claim
1. A system for a removable syringe micro pump with volute spring, comprising:
- a pump housing having a first end and opposite thereto an attaching end, and at least one sidewall there between, the pump housing having a base proximate to the first end and, the attaching end having an attacher structured and arranged to temporarily engage a syringe having a barrel with an open end opposite from a nozzle, the attacher structured and arranged to attach the attaching end to the open end of the syringe;
a volute spring nested within the pump 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 a width of a coil, the volute spring having an extended second position wherein the release of tension extends the volute spring normally away from the removable syringe micro pump, the volute spring having 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.

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.

14. A system for a removable syringe micro pump with volute spring, comprising:
-
a cylindrical pump housing having a first end with a base and opposite thereto an attaching end providing at least one flange structured and arranged to temporarily bind with a set of finger grips provided by a syringe to which the cylindrical pump housing may be temporarily attached, the cylindrical pump housing having a central longitudinal axis; a volute spring disposed within the cylindrical pump housing proximate to the base and about the longitudinal axis, the volute spring being axially compressible to fit within the cylindrical pump housing when a distal end of the volute spring is compressed to provide a compressed first position, a height of the volute spring being about the same as a length of the cylindrical pump housing, the volute spring further selected to have a diameter sufficient to slide within a barrel of a syringe, the distal end of the volute spring structured and arranged to engage a plunger seal of the engaged syringe as the volute spring transitions to an extended second position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for using a removable syringe micro pump with volute spring to dispense a solution from a syringe, comprising:
-
providing a syringe having a barrel extending between a nozzle and a set of finger grips, a plunger seal disposed within the barrel and proximate to the set of finger grips, a solution disposed between the plunger seal and the nozzle; providing a removable syringe micro pump including; a cylindrical pump housing having a first end with a base and opposite thereto, an attaching end providing at least one flange structured and arranged to temporarily bind with the set of finger grips of the syringe, the cylindrical pump having a central longitudinal axis; a volute spring disposed within the cylindrical pump housing proximate to the base and about the longitudinal axis, the volute spring being axially compressible to fit within the cylindrical pump housing when a distal end of the volute spring is compressed to provide a first tensioned position, a height of the volute spring being about the same as a length of the cylindrical pump housing, the volute spring further selected to have a diameter sufficient to slide within the barrel of the syringe, the distal end of the volute spring structured and arranged to engage a plunger seal of the engaged syringe; and a volute spring restrainer structured and arranged to restrain the volute spring in the initial tension position until released by an operator; attaching the removable spring loaded micro pump to the syringe; and releasing the volute spring restrainer to permit the distal end of the volute spring to engage the plunger seal of the syringe, wherein, the release of tension from the first position permits the distal end of the volute spring to move the plunger seal towards the nozzle of the syringe, thereby, dispensing the solution from the syringe. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34)
