Helix was developed especially to test whether inside instruments and tubes with narrow internal lumen steam sterilization was effective. In 2009 after years of debate and discussions Helix Device was written into the EN 285 standard under Amendment A2. The EN 285 + Amendment A2: 2009 are specifying the Helix Test (Hollow A) to be used as Bowie Dick Test when hospitals are sterilizing Hollow Loads. Next to that Bowie Dick Helix Test is an obligatory test for class B Bench Top Steam sterilizers as per EN 13060 + A2: 2010.<\/p>\n
Indicator reaches the end-color 134\u00b0C \u2013 3,5min \/ 121\u00b0C \u2013 15min.<\/p>\n
Failures which are picked-up by the BDHT are:
\u2022 Sterilization temperature too low
\u2022 Sterilization holding time too short
\u2022 Insufficient vacuum in depth and in number of vacuum pulses
\u2022 Insufficient air removal from hollow devices
\u2022 Insufficient steam penetration in hollow devices
\u2022 Leakage of piping\/valves\/door seals
\u2022 Detection of presence of small volume inert gases in steam supply
\u2022 Detection of excessive amounts of condensate<\/p>\n
The BDHT consists out of the following items:
1 piece of Helix device (Teflon with 1,5 mtr long tube) for 500 cycles, 100 (or 250) pieces of Chemical indicator strips with adhesive on the back, 1 piece of Cotton bag, 1 piece of Direction For Use (DFU) with color change images<\/p>\n","protected":false},"excerpt":{"rendered":"
