General Instructions; Intended Use; Product Description - VTI Select Ergo Gebrauchsanleitung

1 General instructions

These operation instructions are valid for the medical pressure regulators of the type "Select 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 the customer service in the case of malfunction and if 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 independently of a
fixed gas supply system. It is connected to the output connection of a cylinder valve and reduces the
cylinder pressure to a low, constant value. This constant low pressure (backpressure) enables the
provision of a defined flow that is largely independent of the cylinder pressure.
The Pico Ergo pressure regulator is suitable for use by emergency services, in clinics and hospitals as
well as in the area of home care - It is not suitable 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 (9)). It
is equipped with an inlet connection (1), via which the connection to the cylinder valve is made. The
connector is standardized and specific to the type of gas. The current cylinder pressure can be read from
the pressure gauge (2) as soon as the valve at the cylinder is opened. The pressure gauge is rotatable
and can be adjusted for optimum readability depending on the situation.
The pressure regulator is equipped with a flow outlet whose gas delivery can be adjusted in fixed steps by
means of a handwheel (7). The handwheel is scaled in l/min.
The flow outlet is equipped with a hose nipple (4a) or a threaded connection (4b). This outlet is provided
for direct patient treatment e.g. via respirator mask or nasal cannula.
The pressure regulator also releases gas even if the handwheel is set between adjacent settings. In this
case, the flow is also approximately between the two adjacent levels. This function is designed to ensure
patient safety. To ensure that the patient receives a precisely defined dose at all times, you must make
sure that the handwheel is correctly engaged in the desired setting!
The flow outlet is not suitable for operation with downstream medical equipment, e.g. ventilators or flow
meters. For this purpose, the pressure regulator can be fitted with one or two pressure outlets (5). A
pressure outlet offers a pressure, which is regulated to 5 bar, and the possibility to withdraw a high flow
rate (>120 l/min). The connection is designed as a plug-in coupling or threaded connection (5) that closes
automatically when the connected appliance is removed.
The pressure regulator is not suitable for use in driving surgical tools!
WARNING: 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 may override
the protective function 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 in the case of oxygen, oxygen mixtures and nitrous oxide!
