7.5.3.47 IfcMedicalDevice

Equipement médical
Medizinisches Gerät

A medical device is attached to a medical piping system and operates upon medical gases to perform a specific function. Medical gases include medical air, medical vacuum, oxygen, carbon dioxide, nitrogen, and nitrous oxide.

Outlets for medical gasses should use IfcValve with PredefinedType equal to GASTAP, containing an IfcDistributionPort with FlowDirection=SINK and PredefinedType equal to COMPRESSEDAIR, VACUUM, or CHEMICAL, and having property sets on the port further indicating the gas type and pressure. Tanks for medical gasses should use IfcTank with PredefinedType equal to PRESSUREVESSEL, containing an IfcDistributionPort with FlowDirection=SOURCE and PredefinedType=CHEMICAL, and having property sets on the port further indicating the gas type and pressure range.
