Absaugkatheter zur Verwendung im Atemtrakt
Sondes d'aspiration pour les voies respiratoires
La présente Norme européenne spécifie les exigences relatives aux sondes en matière plastique, prévues pour l'aspiration dans les voies respiratoires. Les sondes d'aspiration spécialisées telles que celles qui comportent plusieurs lumières, sont exclues du domaine d'application de la présente norme. Les sondes à bout coudé (sondes Coudé, par exemple) ne sont pas considérées comme des sondes spécialisées et relèvent donc du domaine d'application.

Foreword
This document (EN 1733:2002) has been prepared by Technical Committee CEN/TC 215,
"Respiratory and anaesthetic equipment", the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2003, and conflicting national standards shall be
withdrawn at the latest by May 2003.
This document supersedes EN 1733:1998.
This European Standard is based on ISO 8836:1997 Suction catheters for use in the respiratory tract,
prepared by ISO/TC 121.
It differs from ISO 8836:1997 in that it recognises a distinction between tracheal and endobronchial
suction catheters.
Annex A is informative. Annexes B and C are normative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
This European Standard specifies dimensions and requirements for suction catheters for use in the
respiratory tract.
Size is designated by outside diameter which is important when selecting catheters, because of its
relationship to the ease with which the catheter can be passed through a tracheal or tracheostomy tube
(see EN 1782 for details of tracheal tube standards and EN 1282-1 and EN 1282-2 for details of
tracheostomy tube standards). Requirements for suction catheters made of rubber have been deleted
because such catheters are no longer in general use.
This European Standard recognises the potential for damage to the mucosa through the use of suction
catheters with a terminal orifice only and restricts this tip configuration to endobronchial suction catheters,
which are used under visual guidance.
Flammability of suction catheters, for example if flammable anaesthetics or lasers are used, is a well-
recognized hazard that is addressed by appropriate clinical management, and is outside the scope of
this standard (See ISO/TR 11991)

1 Scope
This European Standard specifies requirements for suction catheters made of plastics materials and intended for use in
suction of the respiratory tract. Specialized suction catheters, e.g. those with more than one lumen, are excluded from
the scope of this standard. Angled tip suction catheters (e.g. Coudé catheters) are not considered to be specialized and
are therefore included in the scope.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated
references, subsequent amendments to or revisions of any of these publications apply to this European Standard only
when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred
to applies (including amendments).

4 Size designation and dimensions
4.1 Size designation
4.1.1 The size of suction catheters shall be designated by the following:
a) the nominal outside diameter of the shaft, expressed in millimetres.
NOTE The size can additionally be expressed in French (Charrière) gauge size.
b) the nominal shaft length, expressed in millimetres.
4.1.2 If a colour code is additionally used to designate the size of the suction catheter, it shall be in accordance
with Table 1. The colour coding shall be applied at the machine end of the suction catheter.
NOTE Use and choice of colour coding for designated sizes not listed in Table 1 are at the manufacturer’s discretion.
4.2 Dimensions
4.2.1 The outside diameter and the minimum inside diameter of suction catheters, excluding the tip, shall be in
accordance with Table 2.
NOTE For the purposes of this European Standard, the French (Charrière) gauge system of size is based on the outside
diameter of the shaft gauged in steps of thirds of a millimetre (1 millimetre corresponds to 3F); the French gauge size is not an

SIST EN 1733:2003
EN 1733:2002 (E)
SI unit. Size designation in millimetres facilitates matching suction catheter outside diameter to the inside diameter of the
tracheal or tracheostomy tube.
4.2.2 The minimum inside diameter at the tip shall be not less than 90 % of the minimum inside diameter
specified in Table 2.
4.2.3 The actual shaft length shall be the marked shaft length subject to a tolerance of ± 5 %.
