TEST PROGRAMS
GENERAL
To protect the safety of users and patients, a fundamental process like sterilizing medical devices should be periodically checked.
In this regard,
Millennium B offers the possibility of, simply and automatically, executing two distinct test programs:
•
Helix/BD Test
•
Vacuum Test
The HELIX/BD Test program executes a cycle at 134 °C characterized, however, by a sterilization phase of a particular duration (3.5 min); the
cycle has a fractionated vacuum phase similar to that used in the POROUS and HOLLOW programs.
Using a suitable device, it is possible to evaluate the correct penetration of the steam inside hollow loads (see the following paragraph).
This cycle is also suitable for measuring the penetration of the steam inside porous loads (
Bowie & Dick test pack).
On the other hand, the
Vacuum Test program allows checking the perfect seal of the sterilizer's entire plumbing system.
By measuring the variation in the degree of vacuum in a certain span of time and comparing it with pre-set limit values, it is possible to determine
the effectiveness of the seal of the sterilization chamber, the various tubes and the cut-off devices.
HELIX/BD TEST
To select the
HELIX/BD Test program, press the Test Selection key one or two times until the display reads:
H E L I X / B D T E S T
1 3 4 . 0 ° C
2 . 1 5 b a r 0 3 : 3 0
The test device is a 1.5-m tube made of PTFE with an internal diameter of 2 mm, with a small sealed screw capsule attached to one end,
capable of holding a suitable amount of chemical. The other end of the tube is left free to allow the penetration of the steam and evaluate its
effectiveness.
To execute the test insert the chemical indicator, which consists of a strip of paper with a special reagent ink, inside the capsule of the device
(which is always to be used perfectly dry). Tighten the capsule so that seepage through the gasket seal will not be possible.
