1. A system comprising:
a control unit that provides an electrical signal;
a computing device that is communicatively coupled to the control unit and includes a memory component that stores logic and a processor for executing the logic;
a tubing member assembly including an outer pipe member having an inner region, the outer pipe member defining a static diameter and an inner pipe member, the inner pipe member having an outer surface, the inner pipe member defining a dynamic diameter configured to change from at least a first inner pipe member value to a second inner pipe member value, wherein the dynamic diameter is smaller than the static diameter, and wherein the inner pipe member is disposed within the outer pipe member; and
an elastomer member, communicatively coupled to the control unit, that is disposed between the outer pipe member and the inner pipe member such that an inner area of the elastomer member is disposed on the outer surface of the inner pipe member, and wherein the elastomer member is configured to expand from a first position to a second position to constrict the dynamic diameter from the first inner pipe member value to the second inner pipe member value responsive to receiving the electrical signal from the control unit.
