Abstract: A portable, gravity-type peritoneal dialysis cycler for controlling during each dialysis cycle the volumetric flows of an exchange fluid into and out of the peritoneal space of a patient, and the dwell time of the exchange fluid therein. The cycler comprises an easily assembled vertical stand supporting a load cell from which a pair of exchange fluid filled bags are suspended above the level of the patient's peritoneal space and a pair of drain bags are suspended therebelow. The single load cell is connected to an electronic scale circuit. A single tube is connected at one end to a surgically implanted catheter leading to the patient's peritoneal space, and at its other end to a "Y" fitting connected to a tube assembly from the exchange fluid bags and to a tube assembly leading to the drain bags. The fluid exchange bag and the drain bag tube assemblies are easily inserted into and controlled by zero loading force, normally closed, solenoid control valves.

Abstract: This invention is directed to a board game comprising a board formed with a plurality of spaced holes disposed in columns and rows, inserts adapted to fit within individual holes in the columns and rows to form a playfield having a first series of spaced, parallel channels and a second series of spaced, parallel channels perpendicular to the first channels extending between the inserts, barrier elements disposed at selected positions about the perimeter of the playfield and consecutively-numbered game pieces movable within the first and second channels. The object of the game is to arrange the game pieces in an array along the first and second channels within the playfield so that the numbers on the game pieces in each column, row and diagonal of the array add to the same number.
