A dispenser includes a dock configured to be fixed in place at a use device and a solid product holder configured to be removably secured to the dock. The dock has a first portion including a fixation element that is configured to fix the dock in place at the use device and a second portion including a receiving structure. The solid product holder includes a retaining structure, a base, and a support structure. The retaining structure is configured to removably secure the solid product holder to the receiving structure at the second portion of the dock. The base defines a plurality of apertures that form an open area at which the liquid is received at the solid product holder. The support structure extends from the base and defines an internal volume for holding the solid product at the solid product holder.

A method and apparatus for obtaining a product chemistry from a slid block of caustic material is provided. The product is housed within a capsule which is positioned inside a turbulent flow dispenser, which utilizes fluid to erode the block and produce a concentrated solution. The fluid characteristics can be adjusted in the field to achieve a predetermined concentrate level of the solution. The capsule provides a safe and convenient means for handling, storing and shipping the caustic block without exposing the operator or handler to the hazardous material. The capsule includes nested components which can be rotated between a closed or sealed position and an open use position.

A method for obtaining a chemical concentration from a chemical composition and a fluid includes introducing the fluid through ports in a manifold diffuse member positioned adjacent a chemical composition and adjusting, with a fluid valve, characteristics of the flow of the fluid through the ports in the diffuser manifold to obtain and maintain a chemical concentration. The amount of liquid allowed through the ports modifies the turbulence of the liquid, thereby modifying the erosion rate of the chemical composition. An apparatus for adjusting characteristics of the flow of a fluid contacting a solid product to form a product chemistry includes a diffuser manifold having a manifold diffuse member comprising ports therethrough and a fluid valve for controlling the flow rate of a fluid moving through the plurality of ports and diverting the fluid through various flow paths.

A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition, the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

A method of preparing reagents includes inserting a cartridge into an instrument. The cartridge includes a plurality of reagent enclosures disposed in a cavity of the cartridge and exposing a port to an exterior of the cartridge. Each reagent enclosure includes a reagent container including a reagent and an internal cavity defining a compressible volume, an opening defined through the reagent container to the internal cavity. The method further includes connecting a plurality of fluid ports to the openings of the plurality of reagent enclosures; applying a solution through the fluid ports to at least partially fill the plurality of reagent enclosures; and cycling a pressure of the cavity, whereby for each of the reagent enclosures, during increasing pressure, the solution enters the internal cavity of the reagent container, combines with the reagent, and compresses the compressible volume, and during decreasing pressure, the compressible volume decreases and the reagent is ejected through the opening.

This disclosure relates to making medical solutions. In certain aspects, a method is performed by a data processing apparatus. The method includes introducing liquid into a container that contains a dissolvable solid concentrate in a manner so that a layer of solution above the solid concentrate is maintained at a depth that allows the liquid introduced into the container to agitate the solution adjacent to the solid concentrate to cause mixing of the solid concentrate with the solution.

A dispenser assembly for controlled hydro-injection release of an erodible solid cartridge into a liquid. The dispenser assembly includes a fluid flow member with an inlet for attaching to a pressurized fluid line and an outlet. A hydro chamber with a hydro-injector member is provided in the fluid flow member. The hydro-injector member has an inlet opening which faces the inlet of the fluid flow member and outlet opening. A cartridge holding member is removably attached to the fluid flow member and is configured to house the erodible solid cartridge in an activation chamber. A plate is positioned in engagement with the hydro-injector member. An expandable member extends from the plate. The hydro-injector and the plate control the rate of erosion of the erodible solid cartridge.

This dialysis device is configured so that residual liquid in a powder container 42 and a bypass path 51 can be drained. Accordingly, the dialysis device is provided with: a first liquid draining path 71 connecting a clean water supply path 31 to a stock solution supply path 44 on the upstream side of a liquid feed pump 33; a second liquid draining path 72 connecting the clean water supply path to a dialysate discharge path 32 on the downstream side of the liquid feed pump; and an opening path 77 allowing a branch path 43 to communicate with the outer space by opening an on-off valve 78. By opening the on-off valve of the opening path and actuating the liquid feed pump, a liquid in the powder container 42 and a liquid in the bypass path 51 can be discharged through the first liquid draining path and the second liquid draining path.
