Abstract

A bag arrangement for containing fluid for use with an infusion pump. The bag arrangement includes a first end and a second end, and includes a panel defining a interior chamber. The arrangement further includes a fluid outlet port in the panel, the outlet port in fluid communication with the interior chamber. An elongated hollow member is in fluid communication with the port, and extends from the first end toward the second end of the bag arrangement tangentially along the panel.

Claims

1. A bag arrangement for containing fluid for use with a fluid pump, the bag arrangement comprising:

a bag including a first wall and an opposed second wall defining an interior chamber, the bag including a first end and a second end; and

a fluid outlet port in fluid communication with the interior chamber, the port including an elongated hollow member extending through the first wall, and being oriented tangentially to the first wall;

wherein the elongated hollow member extends;

along the first wall within the interior chamber adjacent and toward the first end of the bag, through the first wall, and toward the second end of the bag along an exterior of the first wall; and

wherein the bag further includes a first half including the first end and a second half including the second end, wherein the port is located in the first half of the bag.

2. The bag arrangement of claim 1, wherein the first wall comprises at least two overlapping wall segments joined at a seam, and the port in the first wall is formed at the seam.

3. The bag arrangement of claim 1, wherein the hollow elongated member includes a tube including a first end within the interior chamber, a middle at an opening through the first wall, and a second end outside of the interior chamber, and wherein the second end includes a fluid conduit connector in fluid communication therewith.

4. The bag arrangement of claim 3, wherein the first end of the tube is coupled to the first wall, and wherein the middle of the tube is sealed to the first wall.

5. The bag arrangement of claim 3, wherein the fluid conduit connector comprises a Luer activated valve.

6. The bag arrangement of claim 1, wherein the first half includes a narrow portion.

7. A bag arrangement for containing fluid for use with a fluid pump, the bag arrangement comprising:

a panel defining a interior chamber, a first end and a second end;

a first half including the first end and a second half including the second end;

a fluid outlet port opening in the panel located in the first half of the bag arrangement, the outlet port opening in fluid communication with the interior chamber;

an elongated hollow member in fluid communication with the port opening, and extending in a direction from the port opening toward the second end tangentially along an exterior of the panel.

8. The bag arrangement of claim 7, wherein the elongated hollow member further extends internally into the interior chamber from the port toward the first end of the bag arrangement and tangentially along an interior of the panel.

9. The bag arrangement of claim 7, further including a second elongated member extending from the port toward the first end of the bag arrangement within the interior chamber.

10. The bag arrangement of claim 7, wherein the elongated hollow member includes a tube extending from within the interior chamber adjacent the first end of the bag arrangement, through an opening in the panel defining the port, and toward the second end of the bag arrangement along the panel.

11. The bag arrangement of claim 7, wherein the panel comprises at least two overlapping wall segments joined at a seam, and the port in the panel is formed in the seam.

12. The bag arrangement of claim 7, wherein the hollow elongated member includes a tube including a first end within the interior chamber and a second end outside of the interior chamber, and the second end includes a fluid conduit connector in fluid communication therewith.

13. The bag arrangement of claim 12, wherein the first end of the tube is coupled to the panel.

14. The bag arrangement of claim 12, wherein the fluid conduit connector comprises a Luer activated valve.

15. A pump system comprising:

an enclosure arrangement defining a chamber, the chamber accessible through an opening;

a pump mounted to the enclosure arrangement to close the opening to the chamber;

a bag arrangement containing fluid located in the chamber, the bag arrangement including;

a panel defining a interior chamber, the bag arrangement including a first end and a second end;

a first half including the first end and a second half including the second end;

a fluid outlet port opening in the panel located in the first half of the bag arrangement, the outlet port opening in fluid communication with the interior chamber; and

an elongated hollow member in fluid communication with the outlet port opening, and extending from the port opening toward the second end of the bag arrangement tangentially along an exterior of the panel; and

a fluid conduit arrangement in fluid communication with the elongated hollow member to complete a fluid path from the bag arrangement to the pump.

16. The pump system of claim 15, wherein the elongated hollow member further extends internally from the outlet port into the interior chamber toward the first end of the bag arrangement tangentially along an interior of the panel.

17. The pump system of claim 15, wherein the pump includes a control module, a pressure plate detachably mounted to the control module, and an adapter portion detachably mounted to the pump.

18. The pump system of claim 15, wherein the enclosure arrangement is formed of rigid material.
