All technical content of this Standard is mandatory.
This Standard replaces GB 18671-2002 “Intravenous infusion needles for
single use.” The main differences between this Standard and GB 18671-2002
are as follows.
- the applicable scope was expanded to infusion needles for. gravity feed-
type infusion sets, infusion sets used with pressure infusion equipment,
and transfusion sets; the corresponding requirements were added;
- added infusion needle with 0.36 mm needle tube specification and
corresponding requirements;
- changed product mark to specification mark;
- made connection base requirements mandatory;
- re-categorized the requirement relating to inner diameter for quick
evaluation of needle tube openness to flow; it is now a requirement in
informational Annex form for further evaluation of needle tube and needle
tip quality; eliminated the qualitative needle tip puncture force test
- changed pH test to titrimetric method;
- eliminated the ethylene oxide residue quantity requirement for infusion
needles sterilized with ethylene oxide; added a requirement that
packaging make use of dialytic materials;
- revised mark and packaging requirements;
- eliminated the exit-factory inspection.
Annex A and Annex B of this Standard are normative. Annex C and Annex D
are informative.
This Standard was proposed by China State Food and Drug Administration.
This Standard shall be under the jurisdiction of China National Technical
Committee on Standardization of Medical Infusion Devices.
Drafting organizations of this Standard. Zhejiang Kangdelai Medical Apparatus
Stock Co., Ltd., Jinan Quality Supervision and Inspection Centre for Medical
Devices of China State Food and Drug Administration.
There are two main forms in which intravenous infusion needles are supplied.
One is supplied to hospitals together with infusion and transfusion sets.; the
other is supplied to hospitals as independent commercial products. The first
one accounts for the great majority of such needles in China. The sterility,
packaging, and labelling requirements of this Standard do not apply to
intravenous infusion needles supplied together with infusion and transfusion
To meet different clinical needs, this Standard does not limit combinations of
needle tube outer diameter and length. However, in view of the need to provide
identification for product sales and clinical use, this Standard requires labelling
of needle tube length, tube wall type, and needle tip type in addition to labelling
of needle tube outer diameter.
As a transitional measure, GB 18671-2002 classified the G/T 1962 requirement
on inner conical fittings as a suggested requirement. Seeing as many
enterprises have gradually adopted semi-rigid 6% inner conical fittings, this
version has reclassified the requirement as mandatory.
Intravenous needles for single use
1 Scope
This Standard specifies requirements for single-use intravenous infusion
needles (hereinafter referred to as “infusion needles”) of which the nominal
outer diameter is 0.36 mm ~ 1.2 mm to ensure adaptability to gravity feed-type
infusion sets, infusion sets used with pressure infusion equipment, and
transfusion sets.
This Standard provides a guide to the properties and quality norms for the
materials used in infusion needles.
Clause 3 to 8.1, and 8.3 of Clause 8 of this Standard give quality norms for
infusion needles supplied with infusion and transfusion sets.
2 Normative references
The following standards contain the provisions which, through reference in this
Standard, constitute the provisions of this Standard. For dated references,
subsequent amendments (excluding corrections) or revisions do not apply to
this Standard. However, the parties who enter into agreement based on this
Standard are encouraged to investigate whether the latest versions of these
documents are applicable. For undated reference documents, the latest
versions apply to this Standard.

4 Examples of marking
4.1 Infusion needle specification mark is presented in terms of needle tube
nominal diameter, nominal length, tube wall type, and angle (α) of first bevel of
needle tip. The outer diameter and length are expressed in “mm”. The tube wall
type is represented as RW (regular wall), TW (thin wall), or ETW (extra thin
wall). The angle of the first angular plane of the needle tip is represented as LB
(long bevel angle) or SB (short bevel angle).
4.2 For an infusion needle that is compliant with This Standard, that has a
needle tube nominal outer diameter of 0.7 mm, a nominal length (L) of 30 mm,
and a tube wall type of thin wall, and that has a needle tip first bevel angle that
is a long bevel angle, the specification mark is.
0.7 X 30 TW LB
Note 1. The needle tube wall thickness and the needle tip first bevel angle can be selected
according to need. See also Clause D.1.
Note 2. This Standard recommends use of thin-wall or extra-thin-wall needle tubes.
5 Materials
The needle tubing used to manufacture infusion needles shall comply with the
requirements of GB 18457.
Infusion needle components (including lubricants) that come into contact with
pharmaceutical liquids shall also comply with the requirements of Clause 7 and
Clause 8.
6 Physical requirements
6.1 Color labelling
8.2 Sterility
Infusion needles in primary packaging shall undergo confirmed sterilization
processes to make the product sterile.
Note 1. GB/T 14233.2-2005 prescribes a sterility test method, but this method cannot be used
to verify the sterilization results of a sterilized lot.
Note 2. See GB 18279 or GB 18280 for suitable validation and routine control of the sterilization
8.3 Bacterial endotoxins
When testing according to GB/T 14233.2, draw 5 mL of extracting medium into
a syringe and connect it to an infusion needle. After injecting until the inner
cavity of the infusion needle is full, seal the head end of the needle. Place
together in a 37 °C constant-temperature box, and extract for 1 h. Inject the
extracting medium that is remaining in the syringe through the inner cavity of
the infusion needle. Collect all of the extract fluid, and test it. The bacterial
endotoxin limit shall be less than 0.5 EU/mL.
Note. YY/T 0618 presents a guide for bacterial endotoxin routine monitoring and alternating-lot
