Dialysate bag seal breakage sensor incorporated in dialysate bag management
First Claim
1. A medical fluid supply bag stand for mounting a medical fluid supply bag for use during a therapy, the medical fluid supply bag including an upper fluid carrying portion and a lower fluid carrying portion, the bag stand including:
- a support pole;
at least one shelf movably connected to the support pole, the shelf configured for mounting only the upper fluid carrying portion of the medical fluid supply bag, the shelf further configured to support the medical fluid supply bag while in use during the therapy; and
a sensor mounted on the shelf for sensing liquid in the upper fluid carrying portion of the medical fluid supply bag, the sensor operable during the therapy for determining whether liquid is present in the upper fluid carrying portion.

Abstract
A stand for a medical fluid treatment, a system for supporting medical fluid bags, and a method for testing and sensing whether a bag or a seal in a chamber of a multi-chamber bag has been broken prior to providing therapy. A stand stores one or more medical fluid bags, each bag stored on a single shelf. Each shelf has a sensor for sensing the presence or absence of fluid in the bag, and reporting the status of the bag to a central location, such as a computer. The sensor can also detect and report on whether fluid has leaked from the bag, or in the case of bags with two or more chambers, if a leak in a frangible seal separating the chambers has developed.

9. A method of sensing medical fluid during a medical therapy, the method comprising:
-
providing a medical fluid supply bag stand, wherein at least one shelf is movably connected to the stand, the at least one shelf configured for mounting only a portion of a medical fluid supply bag for use during the medical therapy, the medical fluid supply bag including an upper fluid carrying portion and a lower fluid carrying portion; mounting only the upper fluid carrying portion of the medical fluid supply bag on the at least one shelf; during the medical therapy, sensing a presence of the medical fluid supply bag with a sensor mounted on the at least one shelf; and during the medical therapy, sensing an absence of liquid in the medical fluid supply bag if a seal separating the upper fluid carrying portion and the lower fluid carrying portion leaks or has been broken. - View Dependent Claims (10, 11, 12, 13, 14)

20. A medical fluid supply bag stand, comprising:
-
a support pole; at least one shelf movably connected to the support pole, the shelf configured for mounting only an upper portion of the medical fluid supply bag; and a sensor mounted on the shelf for sensing liquid in the upper portion of the supply bag, the sensor suitable for determining whether liquid is present in the upper portion, wherein the at least one shelf is configured for storing a medical fluid supply bag having at least two chambers, and wherein the sensor detects liquid in an upper chamber before fluid in the two chambers is mixed and wherein the sensor detects less liquid in the upper chamber after liquid in the two chambers is mixed.
