1. Scope1.1This Standard specifies minimum safety and performance requirements for vacuum devices (see Figure 1). Equipment may be driven by centrally powered piped vacuum systems, fluids, electricity, or manually powered for a variety of applications (see Figure 1).Excluded from the Standard are (a) central power supply (by vacuum/compressed air generation), piping systems of vehicles and buildings, and wall connectors; (b) catheters, drains, curettes, and suction tips; (c) syringes; (d) anaesthetic gas scavenging systems; (e) laboratory suction (see CSA Standard CAN/CSA-Z305.1); (f) autotransfusion systems; (g) passive urinary drainage; (h) closed systems for wound drainage; (i) gravity gastric drainage; (j) orally operated mucous extractors; (k) peristaltic pumps (where collection device is upstream of the pump); and (l) breast pumps.1.2Equipment specified by this Standard may be used for various proce dures including the following applications: (a) liposuction; (b) naso-gastric drainage; (c) oral-nasal suction; (d) thoracic drainage; and (e) uterine aspiration.1.3The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
