Abstract

Fluid supply systems and methods for therapeutic fluid delivery systems, including those used for negative pressure wound therapy (NPWT) systems and methods.

Claims

1. A cartridge for attachment to a fluid delivery system, the cartridge comprising:

a piercing device having a conduit, the piercing device being for piercing a liquid container and creating a fluid communication between the interior of the container and the conduit, the conduit having an outlet connection,

wherein the conduit comprises a pump component actuated by a fluid delivery system to which the cartridge is coupled for pumping liquid from the interior of a container to the outlet connection.

2. The cartridge according to claim 1, wherein the pump component is a flexible conduit which forms a peristaltic pump upon connection to a fluid delivery system having a peristaltic pump actuator.

3. The cartridge according to claim 1, wherein the pump component is a diaphragm pump configured to be actuated by an actuator of a fluid delivery system to which the cartridge is coupled.

4. The cartridge according to claim 1, further comprising a support device for supporting the liquid container.

5. The cartridge according to claim 1, 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.

6. The cartridge according to claim 1, wherein the conduit comprises

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

and

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

8. The cartridge according to claim 1 wherein the piercing device comprises a vent valve.

9. A fluid delivery system for connecting to a cartridge according to claim 1, the fluid delivery system comprising an actuator for actuating the pump component of the cartridge.

10. The fluid delivery system according to claim 9, wherein the actuator comprises a rotor to engage the conduit of a cartridge to form a peristaltic pump.

11. The fluid delivery system according to claim 9, wherein the actuator comprises a push/pull actuator to actuate a diaphragm pump of a cartridge.

7. The cartridge according to claim 7, wherein the pump component is a flexible conduit between the first and second couplings.

12. A fluid supply system comprising:

a support device configured to support a liquid container, wherein the support device comprises;

a base portion with a first lateral extension and a second lateral extension extending from the base portion; and

a slot between the first lateral extension and the second lateral extension; and

a cartridge coupled to the support device, wherein the cartridge is configured to engage a fluid delivery system and wherein the cartridge comprises;

a housing comprising a first end and a second end;

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

a piercing device coupled to a retaining member, wherein the retaining member is configured to engage the slot of the support device; and

a conduit coupled to the piercing device and the first coupling member, wherein the piercing device and the first coupling member are in fluid communication.

13. The fluid supply system of claim 12 wherein the first lateral extension and the second lateral extension form a receptacle, and wherein the piercing device extends into the receptacle when the retaining member is engaged with the slot.

14. The fluid supply system of claim 13 further comprising a liquid container configured for insertion into the receptacle of the support device.

15. The fluid supply system of claim 14 wherein the piercing device is configured to pierce the liquid container when the liquid container is inserted into the receptacle of the support device.

16. The fluid supply system of claim 14 wherein an upper portion of the liquid container comprises a support engagement member.

17. The fluid supply system of claim 16 wherein the support engagement member comprises an extension and an aperture.

18. The fluid supply system of claim 16 wherein the support engagement member is configured to engage a support member coupled to a therapeutic fluid delivery system.

19. The fluid supply system of claim 12 wherein the first lateral extension and the second lateral extension of the support device are curved and tapered.

20. The fluid supply system of claim 12 wherein:

the fluid supply system is coupled to a therapeutic fluid delivery system comprising a control housing having a lower support surface; and

wherein the slot is positioned above the lower support surface.

21. The fluid supply system of claim 20 wherein the conduit coupled to the piercing device is not occluded when the retaining member is engaged with the slot and when the lower support surface of the control housing is placed on a flat surface.

22. The fluid supply system of claim 12 further comprising a conduit coupled to the first and second coupling members.

23. The fluid supply system of claim 22 wherein the conduit is configured to engage a pump when the fluid supply system is coupled to a therapeutic fluid delivery system.

24. The fluid supply system of claim 23 wherein the pump is a peristaltic pump.

25. The fluid supply system of claim 12 wherein the cartridge and the support device are integral components.

26. The fluid supply system of claim 12 wherein the cartridge and the support device are separate components.

27. 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

wherein the cartridge comprises a piercing device;

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; and

piercing the liquid container with the piercing device.

28. The method of claim 27 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.

29. The method of claim 27 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 member extends into the receptacle.

30. The method of claim 27 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.

31. The method of claim 27 wherein an upper portion of the liquid container comprises a support engagement member and wherein the therapeutic fluid delivery system comprises a support member.

32. The method of claim 31 further comprising engaging the support engagement member of the liquid container with the support member of the therapeutic fluid delivery system.
