Abstract
An extracorporeal blood filtering machine can include a blood circuit, an effluent circuit, and a source fluid circuit and can be controlled by a controller. The extracorporeal blood filtering machine can also include access ports for connecting the source fluid circuit to the blood circuit, as well as blood sensors to detect possible issues with the extracorporeal blood filtering machine. The extracorporeal blood filtering machine can include density sensors and flow sensors that enable it to be more accurate and to operate while being transported. The extracorporeal blood filtering machine can further include a user interface and can display fluid inflow/outflow information. A medical fluid container can automatically empty after being filled. An apparatus for supporting a medical fluid container can include a hanger and an attachment member with the apparatus able to adjust to ensure the medical fluid container remains properly oriented directly under a medical fluid container scale.
Core Innovation
The medical fluid container includes a primary chamber configured to hold a fluid, and a secondary chamber in fluid communication with the primary chamber. The secondary chamber is partially separated from the primary chamber by a first wall that extends from a top of the medical fluid container to an empty-level near a bottom of the medical fluid container. The container further includes a discharge chamber in fluid communication with the secondary chamber, with the discharge chamber partially separated from the secondary chamber by a second wall that extends from the bottom of the medical fluid container to a full-level near the top of the medical fluid container.
When fluid in the primary chamber and the secondary chamber rises above the full-level of the second wall, the fluid within the primary chamber and the secondary chamber empties through the discharge chamber. The emptying continues until the fluid in the primary chamber and the secondary chamber drops to the empty-level of the first wall. This arrangement defines automatic emptying behavior based on the fluid level relative to the full-level and empty-level.
In a method, a medical fluid container is provided that comprises the primary chamber, the secondary chamber partially separated by the first wall, and the discharge chamber partially separated by the second wall. Fluid is added to the primary chamber and the secondary chamber, and when fluid in the primary chamber and the secondary chamber rises above the full-level of the second wall, automatically emptying occurs through the discharge chamber until the fluid drops to the empty-level of the first wall.
Claims Coverage
The document contains two independent claims, an apparatus claim and a method claim, each centered on the same level-driven chamber-emptying structure.
Level-driven emptying via first and second walls forming discharge chamber
A medical fluid container having a primary chamber, a secondary chamber in fluid communication with the primary chamber and partially separated by a first wall to an empty-level, and a discharge chamber in fluid communication with the secondary chamber and partially separated by a second wall to a full-level, wherein when fluid rises above the full-level the fluid empties through the discharge chamber until the fluid drops to the empty-level.
Automatically emptying fluid through discharge chamber when full-level is exceeded
A method where providing the medical fluid container with the primary chamber, the secondary chamber partially separated by a first wall to an empty-level, and the discharge chamber partially separated by a second wall to a full-level, adding fluid to the primary chamber and secondary chamber, and automatically emptying the fluid through the discharge chamber when the fluid rises above the full-level until the fluid drops to the empty-level.
Both independent claims require a container structure with first and second walls defining an empty-level and full-level, and they rely on automatic emptying through a discharge chamber when fluid exceeds the full-level and continues until the fluid reaches the empty-level.
