DIN EN ISO 9170-1-2008 医用气体管道系统用终端设备.第1部分:与压缩医用气体和真空管道系统一起使用的终端设备
Terminal units for medical gas pipeline systems - Part 1: Terminal units for use with compressed medical gases and vacuum (ISO 9170-1:2008); English version of DIN EN ISO 9170-1:2008-10
1.1 This part of ISO 9170 applies to:
a) terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use
with the following medical gases:
-- oxygen;
-- nitrous oxide;
-- medical air;
-- carbon dioxide;
-- oxygen/nitrous oxide mixture [50 %/50 % (by volume)];
b) terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use
with the following gases and services:
-- oxygen-enriched air;
-- air for driving surgical tools;
-- nitrogen for driving surgical tools;
-- vacuum.
NOTE 1 Different names or symbols are used for air for driving surgical tools, such as instrument air, surgical air, air
motor, air-700 and air-800.
NOTE 2 The requirements of this part of ISO 9170 can be used as guidelines for terminal units for other gases. These
other gases will be considered for inclusion in this part of ISO 9170 when they come into general use.
It is intended especially to ensure the gas-specific assembly of terminal units and to prevent their interchange
between different gases and services.
1.2 This part of ISO 9170 specifies requirements for terminal units for supply and disposal of nitrogen or air
for driving surgical tools.
1.3 This part of ISO 9170 specifies requirements for probes intended to be connected to the gas-specific
connection point which is part of the terminal unit.
