Agenda
► Discussion on:
–
Progress by CEN/CLC/TC3/WG1 "standard for phthalate labelling" :
–
Labelling requirements, minimum thresholds,
–
IFU information, deadline for implementation
–
The justification for use of phthalates for children, pregnant and nursing women
–
Interpretation of "intended use of such device includes treatment of children, pregnant and nursing
women?
–
Is a precaution in the IFU for vulnerable groups always needed?
–
Interpretation of 'specific justification'?
•
Should there be measurements of phthalate exposure for all products containing phthalates?
•
Is it possible to justify a product containing phthalates, if a phthalate-free product exists for the same
intended use? (and the same price?)
–
Measurements of phthalates.
•
Is a standard available?
•
Could the standard for measurement of food contact materials be applied?

prEN 15986 Requirements for labelling of medical devices
containing phthalates (CEN/CLC/TC3/WG1 )
► Standard still in development so may change (though unlikely)
► May not be ready for 21 March 2010
► Symbol will need to be explained in IFU
► Threshold for labelling: ‘part of the formulation’.
– Why?
• Plasticizer is a significant component of item (20-40%)
• If threshold (eg 0.1%) how to demonstrate? (Eg testing,
methodology)

REACH (1907/2006)
► Article 33
– 1. Any supplier of an article containing a substance meeting the criteria in Article 57
[Annex XIV] and identified in accordance with Article 59(1) in a concentration above
0,1 % weight by weight (w/w) shall provide the recipient of the article with sufficient
information, available to the supplier, to allow safe use of the article including, as a
minimum, the name of that substance.
– 2. On request by a consumer any supplier of an article containing a substance
meeting the criteria in Article 57 and identified in accordance with Article 59(1) in a
concentration above 0,1 % weight by weight (w/w) shall provide the consumer with
sufficient information, available to the supplier, to allow safe use of the article
including, as a minimum, the name of that substance.
The relevant information shall be provided, free of charge, within 45 days of receipt
of the request.

Opinion of the UK MHRA 1/2
► The MHRA has reviewed the SCENIHR report and has concluded that:
– there is no new evidence to suggest that medical devices plasticised with DEHP
present an unacceptable health risk to humans. In particular, there is no proven
effect of exposure to DEHP on male reproductive health – the adverse effect of
concern in the SCENIHR report
– medical devices containing DEHP-plasticised PVC have important clinical benefits
– in view of the proven clinical benefits of PVC medical devices plasticised with DEHP it
would be premature to recommend a change to other plasticisers.

Opinion of the UK MHRA 2/2
► Meanwhile, recognizing that the undesirable characteristics of DEHP-plasticised
PVC represent only one facet of a complex risk-to-benefit equation, it appears
at present that this material is essential in some medical devices used in
critical circumstances. In some situations, coatings that lead to a significant
reduction in DEHP-exposure can improve the total risk-to-benefit ratio. Where
DEHP is not essential, the manufacturer’s risk assessment (required by the
Medical Devices Directive) should lead to the conclusion that alternative
materials that do not result in exposure to DEHP should be used.

Small Bore Connectors
(Luer Connectors)
Small Bore Connectors
► EN 13014: Connections for gas sampling tubes to anaesthetic
and respiratory equipment. BSI appeal against ratification of
Amendment and was successful Amendment nor ratified and
Standard withdrawn (Danger of mis-connection)

Small Bore Connectors
► EN 15546-1: 2008 Harmonised, but causing problems. From
the ‘Introduction’:
– FTG* recommended that the Luer connector should be restricted
to devices intended to be connected to the vascular system or a
hypodermic syringe.
► No alternative for other applications at present.
* Forum Task Group. Set up by CEN Healthcare Forum (CheF) steering
group to consider mis-connection issues

Small Bore Connectors
► UK National Patient Safety Agency proposing use of
‘safer’ (ie non luer) connectors by 31 March 2011
for neuraxial syringes and needles that will not
connect with intravenous devices, to collect samples
and administer medicines by neuraxial routes.
