Abstract

A cartridge system for delivery of medicament includes as membrane placed between two disk magnets that are housed within pump body inserts. The pump body inserts having flow channels and fluid openings are between two inlet/outlet members. The inlet/outlet members each having a fluid outlet component and fluid openings are securely engaged to two reservoirs containing fluid medicaments.

Claims

1. A cartridge system, comprising:

a first reservoir;

a second reservoir;

a first pump body insert comprising;

a first fluid receiving opening,

a first fluid discharge opening,

a plurality of first pump body insert channels configured to direct a first flow of fluid from the first fluid receiving opening through the first fluid discharge opening;

a second pump body insert comprising;

a second fluid receiving opening,

a second fluid discharge opening,

a plurality of second pump body insert channels configured to direct a second flow of fluid from the second fluid receiving opening through the second fluid discharge opening;

a pump membrane positioned between the first pump body insert and the second pump body insert, wherein the plurality of first pump body insert channels and the plurality of second pump body insert channels provide pump membrane support and limit deformation and reverse flow of fluid; and

a plurality of magnets associated with the pump membrane and configured to apply a magnetic force to the pump membrane,

wherein the first pump body insert is in fluid communication with the first reservoir, and

wherein the second pump body insert is in fluid communication with the second reservoir, and

wherein the pump membrane moves according to the magnetic force applied.

2. The cartridge system of claim 1, wherein a first magnet of the plurality of magnets is located adjacent a first side of the pump membrane, and wherein a second magnet of the plurality of magnets is located adjacent a second side of the pump membrane.

3. The cartridge system of claim 1, wherein the plurality of magnets includes a first magnet and a second magnet, wherein the first magnet is located adjacent a first side of the pump membrane, wherein the second magnet is located adjacent a second side of the pump membrane, and wherein the pump membrane deflects according to the magnetic force applied.

4. The cartridge system of claim 1, wherein the pump membrane is pre-stressed.

5. The cartridge system of claim 1, further comprising a plurality of valve membranes.

6. The cartridge system of claim 1, further comprising a first inlet/outlet member in fluid communication with the first reservoir and the first pump body insert and a second inlet/outlet member in fluid communication with the second reservoir and the second pump body insert.

7. The cartridge system of claim 6, further comprising a first valve membrane located at a region where the first pump body insert fluidly communicates with the first inlet/outlet member and a second valve membrane located at a region where the second pump body insert fluidly communicates with the second inlet/outlet member.

8. The cartridge system of claim 1, wherein the first reservoir contains a first fluid medicament and the second reservoir contains a second fluid medicament.

9. The cartridge system of claim 1, wherein the first reservoir and the second reservoir are substantially symmetrical, and wherein the first pump body insert and the second pump body insert are substantially symmetrical.

10. A cartridge system, comprising:

a first reservoir;

a second reservoir;

a first inlet/outlet member in fluid communication with the first reservoir;

a second inlet/outlet member in fluid communication with the second reservoir;

a first pump body insert in fluid communication with the first inlet/outlet member, wherein the first pump body comprises;

a first fluid receiving opening,

a first fluid discharge opening,

a plurality of first pump body insert channels configured to direct a first flow of fluid from the first fluid receiving opening through the first fluid discharge opening;

a second pump body insert in fluid communication with the second inlet/outlet member, wherein the second pump body comprises;

a second fluid receiving opening,

a second fluid discharge opening,

a plurality of second pump body insert channels configured to direct a second flow of fluid from the second fluid receiving opening through the second fluid discharge opening;

a pump membrane positioned between the first pump body insert and the second pump body insert; and

a plurality of magnets adjacent the pump membrane.

11. The cartridge system of claim 10, further comprising a first valve membrane and a second valve membrane, wherein the first valve membrane is located at a region where the first pump body insert fluidly communicates with the first inlet/outlet member, and the second valve membrane is located at a region where the second pump body insert fluidly communicates with the second inlet/outlet member.

12. The cartridge system of claim 10, wherein a first magnet of the plurality of magnets is located adjacent a first side of the pump membrane, wherein a second magnet of the plurality of magnets is located adjacent a second side of the pump membrane, and wherein the pump membrane deflects in response to a magnetic force applied by the first magnet and the second magnet.

13. The cartridge system of claim 10, wherein the pump membrane is pre-stressed.

14. The cartridge system of claim 10, wherein the first reservoir contains a first fluid medicament and the second reservoir contains a second fluid medicament.
