Abstract: A coupling device for coupling a patient-side medical line to an equipment-side medical line. The device includes two parts, one fluidly coupled to each medical line, and each part having a seal that seals the respective medical line when the parts are disconnected. When the parts are connected, the seals unseal the medical lines so as to establish fluid communication between the medical lines. The parts are connected together by way of a coupling that detaches when subjected to a sufficient separation force. The coupling may be a snap-fit mechanism incorporating a rounded protrusion and a rounded groove that pull apart under a sufficient force. The coupling device provides for a safety breakaway feature while sealing both medical lines when disconnected.

Abstract: A colour selection system is provided which comprises a memory for storing grouping information which categorises each of a plurality of colours into one of a plurality of colour groups. In response to an initial colour selection made by a user, the system determines the group in which the selected colour belongs and generates a selection of colours, using colours which belong to the determined group, from which a user can select one or more further colour in addition to the initially selected colour. The groups of colours are chosen so that the user can only select colours which are deemed to be “harmonious” with each other.
