Abstract: A centrifugal pump (20) for use with a portable fluid collection apparatus for collecting fluid produced by a person, the centrifugal pump comprising a substantially cylindrical pump chamber (26) having an inner diameter (D3), a fluid inlet (24) in fluid communication with said pump chamber, and a fluid outlet (28) in fluid communication with said pump chamber. The pump further comprises an impeller (10) having an outer diameter (D2) and being rotatably mounted on a driveshaft (22) within said pump chamber intermediate said fluid inlet and said fluid outlet, where said driveshaft is rotatable by driving means to rotate said impeller in use and accelerate fluid flowing into said pump chamber through said fluid inlet and out of said fluid outlet. The inner diameter of the pump chamber is substantially equal to or greater than 1.40 times the outer diameter of the impeller.

Abstract: Improvements in a compliant upright drink insulator attachment device that is works with a standard drink insulator. The attachment device uses two parts where one part mates with the second part to slip through a standard insulated drink holder. These insulated drink holders are commonly called coolies or koozies and are manufactured with a central hole to allow for draining. A clip connects a compliant cord to one or both of the two parts. The compliant cord is configured as a coiled cord. A weight is connected to the free end of the compliant cord to keep the insulated drink holder in an upright orientation in the water. The compliant cord allows the weight to move semi independent from the insulated drink holder, and further allows the weight to be stored within the insulated drink holder for storage when it is not being used.
