Intersurgical Launches Anaesthetic Gas Scavenging System (AGSS) Pressure Relief Valves

Pressure relief valvesThe ISO standard 80601-2-13 Anaesthetic Workstation, in section 201.103.3.2.1 ‘Pressure’, states "under single fault conditions, the pressure at the inlet to the Anaesthetic Gas Scavenging System shall not exceed 20hPa (20 cmH2O) with an exhaust flow rate of 75 lpm".

This means that there must be some form of pressure relief in the transfer tube from the APL valve to the AGSS collection equipment, known as the ‘air-brake’.

This is a safety requirement as the transfer tube may become occluded, which will allow the pressure to build up in the breathing system, preventing the patient exhaling. With a valve fitted, the pressure will be released into the atmosphere, reducing the pressure in the breathing system.

Intersurgical has responded to this requirement and has launched two AGSS single-use safety valves, one for use with 30mm scavenging tube – (code 1972000) and the other for use with 22mm scavenging tube – (code 1972001).

For further information please do not hesitate to contact Intersurgical or see full details on the website.
