A bottle apparatus is disclosed. The bottle apparatus includes body including a plurality of sidewalls. The body is divided into a first body and an additional body via one or more dividing members. A cavity of the first body is configured to hold a concentrated product and a cavity of the additional body is configured to hold the concentrated product and a diluent to form a diluted product. The bottle apparatus includes a plurality of openings arranged on a top wall of the body. The bottle apparatus includes one or more transfer members configured to couple to a portion of the plurality of openings. The one or more transfer members are configured to dispense at least one of the diluted product, the concentrated product, or the diluent.

Method, system, apparatus, and/or device for determining when the dewar is filled with a medium. The fill gauge level apparatus includes a cylindrical body. The cylindrical body has a base on one end, a flange on an opposite open end and a cavity. The fill gauge level apparatus includes a fill gauge level device. The fill gauge level device is coupled to the cylindrical body and is positioned within the cavity. The fill gauge level devices includes a sensor for measuring a medium within a shipper. The fill gauge level devices includes an indicator. The indicator provides an indication when the medium has been filled to a threshold level within the shipper.

Flow sensors are provided that can monitor flow conditions. The flow sensor includes a gauge that provides a first level of information about flow through the sensor, and an indicator associated with the gauge that can provided a second level of information about flow through the sensor. The indicator might be in the form of a dial that can rotate about the gauge and might include a locked position for monitoring flow and an unlocked position to rotate the dial about the gauge to reposition the dial. A twisted shaft with varying twist rate is provided to convert linear motion to rotational motion for the gauge.

An extracorporeal circulation apparatus has a blood reservoir temporarily storing blood and a presence information acquisition unit to detect presence or absence of blood at respective wall locations in a two-dimensional array. A control unit determines the position of a blood surface on the basis of consecutive elements in the array having detected blood along at least one of a first direction parallel to the blood surface and a second direction perpendicular to the blood surface.

A volumetric instrument serving as a universal mixture maker. The instrument comprises fixed-shape solute cups that can be submerged in and fastened to solvent containers. The design allows a human operator to run an iterative method which finds a solution to a set of multivariate equations that would otherwise require situation-specific analytical calculations and the use of weighing scales. The iterative method can solve for one or more variables including solute volume, solvent volume, final mixture volume, and final solute concentration level. Cups and containers act as a mechanical calculator with a single parameter for the operator to manually adjust: how much of a solute cup to submerge in a solvent container. The mechanical calculator reduces mixture equations down to two markings for the operator to visually align: an output mixture marking on a cup, and a volumetric marking on a container.
