1. A flow restrictor suitable for use in an interface component, the flow restrictor comprising,
an inlet member which has an inlet channel defined therein;
an outlet member which has an outlet channel defined therein;
wherein the inlet channel and outlet channel are fluidly connected; and
a capillary member which comprises an intermediate channel which is located between the inlet and outlet members, and wherein the intermediate channel is in fluid communication with the inlet channel and outlet channel; and wherein the intermediate channel has dimensions smaller than the dimensions of the inlet and outlet channels;
wherein the flow restrictor comprises a male member and female member which are configured so that they can mechanically cooperate with each other so that the male and female members can be fixed together;
wherein the male member comprises the inlet member, and the female member comprises the outlet member; and
wherein the male and female member each have a pocket which can receive a portion of the capillary member so that a portion of capillary member is contained within the pocket in the male member, and another portion of the capillary member is contained within pocket of the female member.
