Abstract

A fluid delivery system is disclosed including a patient interface device and a bulk container and pump assembly in fluid communication with the patient interface device for supplying a medical fluid to patient. The assembly includes a container body including a closed end and defining an opening leading to an interior chamber for holding the medical fluid, and a pump device closing and sealing the opening in the container body and adapted to draw the medical fluid from the container body and deliver the medical fluid to the patient. A method of supplying a medical fluid to a fluid delivery system is also disclosed and includes providing the bulk container and pump assembly and releasably associating the assembly with a drive device for driving the pump device. The assembly includes a pump device in the form of a gear pump including spur gears that are driven by the drive device.

Claims

1. A bulk container and pump assembly, comprising:

a container body comprising a generally closed end and defining an opening leading to an interior chamber within the container body for holding a medical fluid; and

a pump device closing and sealing the opening in the container body and adapted to draw the medical fluid from the container body and deliver the medical fluid to a patient.

2. A bulk container and pump assembly as claimed in claim 1 wherein the container body is substantially rigid.

3. A bulk container and pump assembly as claimed in claim 1 wherein the pump device comprises a gear pump.

4. A bulk container and pump assembly as claimed in claim 3 wherein the gear pump is disposed in a housing sealing the opening in the container body.

5. A bulk container and pump assembly as claimed in claim 3 wherein the gear pump comprises spur gears.

6. A bulk container and pump assembly as claimed in claim 1 further comprising an encoding device associated with the container body and operable to provide container body information to a sensor.

7. A bulk container and pump assembly as claimed in claim 6 wherein the encoding device comprises an optically readable device.

8. A pump cassette as claimed in claim 6 wherein the container body information comprises at least container body volume information and the type of medical fluid contained in the container body.

9. A bulk container and pump assembly as claimed in claim 1, wherein the container body and pump device are disposable as a singular unit.

10. A fluid delivery system, comprising:

a patient interface device; and

a bulk container and pump assembly in fluid communication with the patient interface device for supplying a medical fluid to patient via the patient interface device, and comprising;

a container body comprising a generally closed end and defining an opening leading to an interior chamber within the container body for holding a medical fluid; and

a pump device closing and sealing the opening in the container body and adapted to draw the medical fluid from the container body and deliver the medical fluid to a patient.

11. A fluid delivery system as claimed in claim 10 wherein the pump device comprises a gear pump.

12. A fluid delivery system as claimed in claim 11 wherein the gear pump is disposed in a housing sealing the opening in the container body.

13. A fluid delivery system as claimed in claim 10 further comprising a plunger disposed in the container body for dispensing the medical fluid from the container body.

14. A fluid delivery system as claimed in claim 10 further comprising an encoding device associated with the container body and operable to provide container body information to a sensor.

15. A fluid delivery system as claimed in claim 14 wherein the encoding device comprises an optically readable device.

16. A fluid delivery system as claimed in claim 14 wherein the container body information comprises at least container body volume information and the type of medical fluid contained in the container body.

17. A fluid delivery system as claimed in claim 10 wherein the container body and pump device are disposable as a singular unit.

18. A fluid delivery system as claimed in claim 10 further comprising a drive device operatively connected to the pump device for driving the pump device.

19. A fluid delivery system as claimed in claim 18 wherein the pump device comprises a gear pump and the drive device is adapted to drive the gear pump.

20. A fluid delivery system as claimed in claim 10 further comprising a fluid level sensor associated with the container body for determining the level of medical fluid in the container body.

21. A fluid delivery system as claimed in claim 20 wherein the fluid level sensor is adapted to sense when the medical fluid reaches a minimum level in the container body.

22. A fluid delivery system as claimed in claim 10 wherein the bulk container and pump assembly is releasably lockable to a base supporting a drive device adapted to drive the pump device.

23. A fluid delivery system as claimed in claim 22 wherein the bulk container and pump assembly is releasably lockable to the base with at least one releasable clamp.

24. A fluid delivery system as claimed in claim 23 further comprising a sensor associated with the releasable clamp and adapted to identify a locked position of the releasable clamp.

30. A fluid delivery system as claimed in claim 15 wherein the encoding device comprises an optically readable device.

25. A fluid delivery system, comprising:

a control unit;

a drive device operatively controlled by the control unit; and

a bulk container and pump assembly in fluid communication, comprising;

a container body comprising a generally closed end and defining an opening leading to an interior chamber within the container body for holding a medical fluid; and

a pump device closing and sealing the opening in the container body and adapted to draw the medical fluid from the container body and deliver the medical fluid to a patient, wherein the drive device is operatively connected to a pump device for driving the pump device.

26. A fluid delivery system as claimed in claim 25 further comprising a fluid level sensor associated with the container body for determining the level of medical fluid in the container body.

27. A fluid delivery system as claimed in claim 26 wherein the fluid level sensor is adapted to sense when the medical fluid reaches a minimum level in the container body and send a signal to the control unit.

28. A fluid delivery system as claimed in claim 25 further comprising a sensor associated with a releasable clamp adapted to releasably lock the bulk container and pump assembly to a base supporting the drive device, and wherein the sensor is adapted to identify a locked position of the releasable clamp and send a signal to the control unit.

29. A fluid delivery system as claimed in claim 25 further comprising an encoding device associated with the container body and operable to provide container body information to a sensor operatively connected to the control device.
