General Instructions; Intended Use; Product Description - VTI Exact Ergo Gebrauchsanweisung

1 General instructions

These operation instructions are valid for all medical pressure regulators of the type "Exact Ergo".
Medical pressure regulators are manufactured with great care. Improper handling, e.g. the use of force
or dropping the device can lead to malfunctions of the pressure display or at the flow adjustment.
Particular care is required when used in conjunction with oxygen!
For this reason, use of this device requires a thorough understanding of and strict adherence to the
operating instructions.
Notify our customer service team of any malfunctions that may occur that you are unable to solve on
your own.
(see: "Eliminating possible malfunctions".)

2 Intended use

The pressure regulator is intended to administer medical gases from gas cylinders during the treatment
and care of patients, independently of a fixed gas supply system.
It is connected to the outlet connection of a cylinder valve and reduces the cylinder pressure to a low,
constant value. This constant low pressure (back pressure) enables the provision of a defined flow that
is largely independent of the cylinder pressure.
The Exact Ergo pressure regulator is suitable for use by emergency services, in clinics and hospitals as
well as in the area of home care - not for use in aseptic, sterile areas!

3 Product description

This medical pressure regulator is designed for a cylinder pressure of up to 300 bar (see type plate (7)).
It is equipped with an inlet connection (1) that is specific to the type of gas, via which the connection to
the cylinder valve is created. The current cylinder pressure can be read from the pressure gauge (2) as
soon as the cylinder valve is opened. The pressure gauge rotates and can therefore be adjusted for
optimum readability depending on the situation.
The outlet provides a fixed flow (e.g.: 5 l/min). It is equipped with a fixed hose nipple (4a) or a threaded
connection (4b).
The pressure regulator is not suitable for use in driving surgical tools!
Each pressure regulator is equipped with a pressure relief valve (safety valve) (3). This is pre-
adjusted at the factory and must not be altered. Manipulation can affect the flow rate accuracy or
lead to the uncontrolled escape of gas.
The pressure regulator, as well as all equipment coming into contact with the gas,
must be kept absolutely free of oil and grease!
There is a risk of fire or explosion in the case of oxygen, oxygen mixtures and
nitrous oxide!
