A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. A fluid trap of a peritoneal dialysis cycler may have a valved connection to a vacuum source or a positive pressure source. The fluid trap can be connected to the vacuum source in order to sealingly engage a flexible membrane of a pumping cassette to a control surface of the cycler during a therapy. Any fluid entering a space between the membrane and control surface can be drawn away and collected in the fluid trap. The fluid trap alternatively can be connected to a positive pressure source in order to aid in separating the membrane from the control surface to facilitate removal of the pumping cassette from the cycler. The fluid trap may include a liquid detection sensor.

A medical treatment system, such as a peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, the peritoneal dialysis system may include a control system that can adjust a volume of fluid infused into a peritoneal cavity to prevent intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle of the one or more therapy cycles to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting a next therapy cycle of the one or more therapy cycles. The control system may also adjust a dwell time of the fluid within the peritoneal cavity during the one or more therapy cycles in order to complete a therapy within a scheduled time period. A cycler may also be configured to have a heater control system that monitors both a temperature of a heating tray and a temperature of a bag of dialysis fluid in order to bring a temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.

Methods and apparatus for chemical delivery are provided herein. In some embodiments, a first reservoir holds a first volume of fluid, receives a carrier gas, and outputs the carrier gas together with vapor derived from the first volume of fluid. A second reservoir holds a second volume of fluid and is capable of delivering a part of the second volume of fluid to the first reservoir. A self-regulating tube extends from the first reservoir to a region above the second volume of fluid in the second reservoir.

A pressure compensation and mixing device for a fluid heater has a mixing unit and a pressure compensation unit. The mixing unit is configured to mix a fluid guided in the mixing unit. The pressure compensation unit is configured to restrict pressure rising in the fluid. The mixing unit and the pressure compensation unit are integrated in a container unit. A bottom side of the container unit is closed by a bottom portion on which at least one connection is located via which the fluid may be discharged.

One aspect of this disclosure provides a packaged air conditioning & heating (PACH) system that comprises a housing, an air cooling system contained within the housing and an air heating system contained within the housing. A first utility access point is located on a first side of the housing and a second utility access point is located on a second side of the housing. The first and second utility access points provide multiple utility access connectivity for the air cooling and heating systems.

Embodiments of the present invention provide a water management system for use on board a passenger transport vehicle. The water management system may be used to address and manage excess humidity, water leaks, or any other instance when water or other liquid may collect at a certain location. The disclosure provides a system for managing excess water and for optionally delivering the water to another location. The removal location may be a disposal outlet or it may be a beneficial use of the collected water on-board the vehicle.

Automated fluid handling system comprising a housing and two or more fluid handling units arranged as interchangeable modular components with an external fluidics section and an internal non fluidics section, and wherein the housing comprises a liquid handling panel with two or more of component positions for receiving said interchangeable modular components such that the external fluidics section is separated from the non fluidics section by the liquid handling panel.

A shallow fluid extractor is configured to remove a low level of a fluid from a designated area. The shallow fluid extractor includes a vacuum pump assembly further including an electrical power source connected to a vacuum and a pump. A pipe assembly is configured within the designated area and connected to the vacuum pump assembly. When the low level of the fluid is reached the vacuum draws the fluid through the pipe assembly into the vacuum pump assembly which is then pumped away by the vacuum pump assembly.
