1. GENERAL INFORMATION
1.1 Introduction
This autoclave is a pre-vacuum sterilizer designed to cover a large field of applications
for hospitals and medical centers as well as pharmaceutical and biotechnological
industries.
The autoclave operates with saturated steam as the sterilizing agent, and has a
temperature of up to 279
º
F and pressure up to 40 psi.
The autoclave is constructed of stainless steel, having a double - walled structure
and is equipped with a steam to steam generator, which supplies clean steam to the
chamber for the sterilization process. There are separate steam lines from the steam
to steam generator to the chamber and from the building steam supply to the jacket.
The autoclave is equipped with one vertical sliding door operated by a hydraulic
system, through two oil cylinders mounted laterally on both sides of the door. The
command pressure of compressed air is transmitted to the oil in the cylinders and
converted into hydraulic pressure, which pushes the pistons up or down, for closing
or opening the door.
The sealing of the chamber is achieved through a heat resistant silicone gasket,
located in a groove on the front side of the autoclave. The gasket is pushed against
the door by steam pressure introduced in the groove, behind the gasket.
Twelve sterilization programs are available, four are intended for unwrapped
instruments (gravity), four for wrapped instruments and packages and four for liquids.
Two test programs are also available, the VACUUM TEST for checking the tightness
of the chamber and piping system and the BOWIE DICK test enabling to check the
efficiency of the sterilization process.
The control system of the sterilizer is based on " State-of -the -Art" microcomputer
technology, ensuring a highly reliable and safe operation. The computerized control unit
ensures a fully automatic operation through the entire cycle, hence after setting the
pre-selected data and starting the operation, no further intervention is necessary.
The selected program, the main phases of the cycle and the status of the machine are
controlled and displayed on digital readouts. For process documentation, the important
information concerning operation is printed in hard copy.
For optimal control accuracy of the sterilization parameters, the system is equipped with
three temperature sensors, three pressure transducers and a pressure switch having
the following functions:
♦
The temperature sensors: 2 measuring the condense temperature (control and printout)
and the drain control output.
♦
The pressure transducers: the chamber pressure (control and monitoring), the jacket
pressure (control) and gasket pressure.
♦
The pressure switch regulates the steam pressure output of the steam generator.
Four pressure gauges measure the gasket, jacket, chamber and steam generator
pressure.
A programming mode, which can be entered by an access code, enables the technician
to set a number of additional parameters and operation modes.
