Systems and methods for positioning fluid supply system

1. A method of securing a liquid container in fluid communication with a therapeutic fluid delivery system, the method comprising:

providing a support device comprising a receptacle configured to receive the liquid container;

providing a cartridge coupled to the support device, wherein:

the cartridge is configured to engage the therapeutic fluid delivery system, and

the cartridge comprises a piercing device in fluid communication with a flexible conduit;

engaging the piercing device with the support device so that the piercing device extends into the receptacle;

placing the liquid container in the receptacle of the support device;

piercing the liquid container with the piercing device; and

engaging the flexible conduit of the cartridge with an actuator carried by the therapeutic fluid delivery system, the flexible conduit being positioned between the actuator and the cartridge.

2. The method of claim 1 wherein:

the cartridge comprises a housing comprising a first end and a second end;

the cartridge comprises a first coupling member proximal to the first end and a second coupling member proximal to the second end; and

the piercing device is coupled to a conduit in fluid communication with the first coupling member.

3. The method of claim 1 wherein:

the support device comprises a slot;

the piercing device is coupled to a retaining member; and

the retaining member is engaged with the slot of the support device when the piercing device extends into the receptacle.

4. The method of claim 1 wherein the support device comprises a base portion with a first lateral extension and a second lateral extension extending from the base portion and wherein the liquid container is placed between the base portion, the first lateral extension and the second lateral extension when the liquid container is placed in the receptacle.

5. The method of claim 1 wherein an upper portion of the liquid container comprises a support engagement member and wherein the therapeutic fluid delivery system comprises a support member.

6. The method of claim 5 further comprising engaging the support engagement member of the liquid container with the support member of the therapeutic fluid delivery system.

7. A cartridge adapted to be attached to a fluid delivery system, the cartridge comprising:

a piercing device having a conduit, the piercing device adapted to pierce a liquid container and to provide fluid communication between the liquid container and the conduit, the conduit having an outlet connection,

wherein the conduit comprises a pump component, the pump component adapted to be positioned between an actuator and the cartridge, the actuator carried by the fluid delivery system, wherein the pump component is adapted to engage the actuator to pump liquid from the container to the outlet connection.

8. The cartridge according to claim 7 , wherein the pump component is a diaphragm pump configured to be actuated by the actuator of the fluid delivery system.

9. The cartridge according to claim 7 , the conduit further comprising:

a first coupling from the piercing device to the pump component; and

a second coupling from the pump component to the outlet connection.

10. The cartridge according to claim 7 wherein the piercing device comprises a vent valve.

11. The fluid delivery system according to claim 7 , wherein the pump component comprises a diaphragm pump, and wherein the actuator comprises a push/pull actuator adapted to actuate the diaphragm pump.

12. The cartridge according to claim 7 , further comprising a support device for supporting the liquid container.

13. The cartridge according to claim 12 , wherein the piercing device is configured to be attached to the support device such that a container placed in the support device is pierced by the piercing device.
