1.5.3

Intended purpose

Name:

LS FLOW

LS DFLOW

Main function:

Designed for measuring the flow and determining the precise

dosage for the supply of oxygen and compressed air. In conjunction

with a hand-held nebuliser, the LS FLOW is used to provide

metered administration of medication aerosols.

Medical indications /

application:

Inhalation and insufflation of oxygen within the scope of oxygen

enrichment via an inhalation mask or a nose latch for patients

breathing by themselves

Together with a hand-held nebuliser administration of water soluble

drugs via an inhalation mask

Specification of the main

function:

Supply of oxygen or compressed air. For oxygen / compressed air

supply, the LS FLOW is connected to an oxygen / compressed air

terminal unit of a central medical gas supply system having a

supply pressure within the supply pressure specified on the

product. For humidification of oxygen from the central gas supply

system, a humidifier may additionally be connected. Supply of

oxygen to the patient takes place via connection tubes and an

inhalation mask or a nose latch. The administration of medication

aerosols via compressed air takes place via connection tubes to a

hand-held nebuliser. The patient presses the inhalation mask

connected to the hand-held nebuliser onto the mouth and nose.

User profile:

Doctor, medically trained staff

Patient groups:

Patients of all ages

Application organ:

Lung

Application time:

For continuous operation; in practice, short-term use on the patient

(< 30 days)

Application site:

The application site is the clinical environment and doctor’s

practices which have a central oxygen / compressed air system.

Cleaning

6.2.1

General

NOTE

Use only all-purpose cleaners which are slightly alkaline (soap solution) and which

contain surfactants and phosphates as the active cleaning agents.

In the event of heavily contaminated surfaces, use concentrated all-purpose

detergent.

CAUTION!

Improper cleaning can cause property damage!

Residues of physiological saline solutions (e.g. sodium chloride) can attack the

surfaces of the product.

Remove residues of physiological saline solutions with a cloth dipped in clean

water. Then dry the product with a dry, lint-free cloth.

CAUTION!

Improper cleaning can cause property damage!

Do not spray cleaning agent directly into the joints or gaps and never use a highpressure cleaning unit!

6.2.2

Cleaning procedure

_ Use the correct dose of all-purpose detergent with water for the degree of surface

contamination and in accordance with the instructions of the detergent manufacturer.

_ Thoroughly wipe off the product with a soft cloth slightly wetted in an all-purpose detergent

solution.

_ Ensure that the product is free from contamination and encapsulated ‌particles of grime.

_ Thoroughly wipe off the product with a soft cloth dipped in clean water.

_ Ensure that the product is free of detergent residues.

_ Dry the product with a dry, absorbent and lint-free cloth.

_ This will help to reduce pathogen growth on the product's surface.
