Fluid channel sealing devices, frangible seals, fluid circuits, associated controllers and methods of using the same are provided for controlling fluid distribution using a reconfigurable blocking element having first and second portions to establish a first configuration free of any open channels such that fluid is prevented from flowing through the channel and a second configuration where the first and second portions are separated to establish an open channel and allow fluid to pass.

Peritoneal dialysis admixing and/or treatment devices, methods, and systems are disclosed. The systems, methods, and devices provide high-level guarantees of sterility and employs relatively inexpensive disposable components to provide pumping. Disclosed systems, methods, and devices and features thereof are adapted for point of use generation of medicament. In particular admixing systems that employ independently-replaceable long term concentrate are disclosed. Features are directed to assurance of sterility and accurate admixing of water and concentrate to generate ready-to-use medicaments and other benefits.

A blood treatment system with pressure sensors may be configured to control blood flow to and from the patient and use readings of the pressure sensors to determine a change in a pressure drop across a flow restriction in the blood circuit to estimate a condition of the machine or the patient, or outputting data responsive to the estimation. Further embodiments employ measurement of pressure drop to detect abnormal viscosity or viscosity variations in order to detect possible infection.

A lightweight compartmentalized collector dolly which readily stores newspapers, glass and metal materials for recycling is disclosed. The newspapers can be neatly stacked and bundled within a dedicated compartment. The collector dolly has a handle and wheels to enable even a child to maneuver the dolly and to collect recyclable materials and sort them during collection. Another container for storing glass materials hangs from a handle support bar and is supported by a half-cup at the bottom. Since the doubled cylindrical compartments have liners and both compartments and liners have draining capabilities at their bottoms, the storing regions in this dolly can be readily cleaned.

An alarm kit for notifying a user of a noncommercial water purification system that the level of liquid with the chemical tank of the system is below a predetermined level includes a float, a housing, an alarm, an activation device and a connection member. This alarm kit can be easily installed by a homeowner or other user of the system and will allow the user to avoid complete depletion of the liquid from the chemical tank. The float either floats on top of the liquid or is submerged therein and will cause movement of the connection member when the liquid level drops below the predetermined level. The connection member will then pivot an arm of the activation device to cause the alarm to be activated in order for the user to be alerted that the liquid within the tank needs to be replaced. The predetermined level is determined by the usual rate of withdrawal of liquid from the tank and the usual time required to replenish the fluid, such as the response interval of a vendor to a request for service.
