Abstract

A cartridge system of a multi-ported drug delivery device with independently actuated collapsible reservoirs, for delivery of medicaments, which includes membranes placed between 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 with communication control through active valves and dynamically stressed membranes. The inlet/outlet members of the cartridge system each having a fluid outlet component and fluid openings are securely engaged to two or more reservoirs containing fluid medicaments. The cartridge system driven by the pump driver system delivers an appropriate dosage of medicament for treatment prescribed.

Claims

1. A multi-ported drug delivery device, comprising:

a pump driver system, said pump driver system comprising a plurality of electromagnetic coils, a controller electrically coupled to said plurality of electromagnetic coils, and a power source;

a cartridge system, said cartridge system comprising;

a plurality of reservoirs, each of said plurality of reservoirs having a substantially symmetrical body with a top end, a bottom end, an outer wall, and an inner wall;

an opening formed at said top end through which medicament is dispensed; and

said inner wall and said bottom end forming a chamber for storage of said medicament;

a plurality of inlet/outlet members, each of said plurality of inlet/outlet members being securely engaged to one of said plurality of reservoirs, each of said plurality of inlet/outlet members having a fluid receiving opening, a fluid discharge opening, and a fluid outlet component, and said fluid receiving opening being in fluid communication with corresponding reservoir;

a plurality of pump body inserts, each of said plurality of pump body inserts having a fluid receiving opening, a fluid discharge opening, a plurality of inlet channels, and a plurality of outlet channels, said fluid receiving opening being in fluid communication with corresponding inlet channels, and said fluid discharge opening being in fluid communication with corresponding outlet channels;

a pump membrane, said pump membrane being between said any two said plurality of pump body inserts; and

a plurality of magnets, said plurality of magnets having a distal end, a proximal end and a cylindrical body connecting said distal and proximal ends, and said proximal end being in contact with said pump membrane and said distal end being housed within one of said pump body inserts,

wherein said plurality of magnets and said plurality of electromagnetic coils are substantially axially aligned.

2. The device of claim 1, further comprising:

a plurality of clamshells, said clamshells having openings to house electromagnetic coils; and

said clamshells having a sensor opening, said sensor opening housing a sensor to help control activation of said electromagnetic coils.

3. The device of claim 1, further comprising:

an infusion set, said infusion set comprising;

a conduit for delivery of medicament, said conduit having a distal end, a proximal end, and a substantially cylindrical body connecting said distal and proximal ends,

wherein said distal end of said conduit is securely attached to a luer slip on said proximal end of said fluid outlet component of said inlet/outlet member, and

wherein said proximal end of said conduit is securely engaged to a cannula and insertion mechanism.

4. The device of claim 1, wherein said pump driver system further comprises a plurality of membrane switches, said plurality of membrane switches being communicatively linked to said controller, and said plurality of membrane switches having a plurality of buttons.

5. The device of claim 1, wherein said pump driver system further comprises a touch screen, display and backlight assembly, said assembly being communicatively linked to said controller, and said touch screen being used to navigate menus, administer medicament, review saved data, modify user settings, or input general information to said device.

6. The device of claim 1, wherein said cartridge system further comprises a plurality of reservoir shells;

and an insulation and sealed layer provided inside each of said plurality of reservoir shells, wherein each of said plurality of reservoirs is mounted within one of said plurality of reservoir shells.

7. The device of claim 1, wherein said cartridge system consists of valve cover channels and rosettes, said valve cover housed within said cartridge system.

8. The device of claim 1, wherein said device is an independently actuated device, said reservoirs are collapsible reservoirs, and said electromagnetic coils are independently juxtaposed flat coils and structurally spaced to conform to a cartridge dual chamber.

9. The device of claim 1, wherein each of said plurality of reservoirs contains a different fluid medicament.

10. The device of claim 9, wherein said fluid medicament is from a group consisting of insulin and glucagon.

11. The device of claim 1, further comprising a plurality of valve membranes, said valve membranes being non-uniformly pre-stressed to form a base, a suspension part and a compliant deflection part and made of a material from the group consisting of Silastic Q7-4840.

12. The device of claim 1, wherein said power source is capable of being recharged using a charging port.

13. The device of claim 1, wherein said plurality of reservoirs are pre-filled with medicaments.

14. A method of delivering medicament, comprising:

providing a multi-ported drug delivery device comprising a pump driver system and a cartridge system;

loading a plurality of pre-filled reservoirs containing fluid medicaments to said cartridge system;

engaging securely said cartridge system and said delivery pump system;
