Foreword
YY 0321 consists of the following parts:
-- Single-use puncture set local anaesthesia;
-- Single-use needle for anaesthesia;
-- Single-use filter for anaesthesia.
This Part is Part 2 of YY 0321.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces YY 0321.2-2009 Single-use needle for anaesthesia.
Compared with YY 0321.2-2009, the main technical changes, except editorial changes,
are as follows:
-- Add a schematic diagram of matching type of cutting edge and lumbar puncture
needle (see Figure 1; Figure 1 of the 2009 edition);
-- Modify the needle tube length of “basic dimensions of needle for anaesthesia” (see
5.1; 3.4 of the 2009 edition);
-- Modify the requirements for the “scale line” of the needle tube (see 5.3.5; 5.2.5 of
the 2009 edition);
-- Modify the requirements for “the inner arc of the bevel of the needle tip of the
epidural puncture needle” (see 5.5.2; 5.4.2 of the 2009 edition);
-- Modify the requirements and test methods for “connection firmness” (see 5.7; 5.6
of the 2009 edition);
-- Add the requirements for “the total content of barium, chromium, copper, lead and
tin in the test solution” in metal ions (see 6.2);
-- Delete “Note 2” on the applicability of the sterility test method in sterility (see 7.1
of the 2009 edition);
-- Modify the requirements for “marking” and delete the requirements for
“instructions for use” (see Chapter 8; Chapter 8 of the 2009 edition);
-- Modify the requirements for “packaging” (see Chapter 9; Chapter 9 of the 2009
edition);
-- Delete the inspection rules of type inspection (see Appendix D of the 2009 edition).

Single-use needle for anaesthesia
1 Scope
This Part of YY 0321 specifies the classification and labeling, materials, physical
properties, chemical properties, biological properties, marking, packaging,
transportation and storage of single-use needle for anaesthesia with a nominal outer
diameter of 0.4 mm ~ 2.1 mm.
This Part applies to single-use needle for anaesthesia for puncture and drug injection
during human epidural nerve block (referred to as epidural anesthesia), subarachnoid
space block (referred to as lumbar anesthesia), combined epidural and lumbar
anesthesia, and local anesthesia of nerve block.

3 Classification and labeling
3.1 Classification
Single-use needle for anaesthesia (hereinafter referred to as needle for anaesthesia) can
be divided into the following categories:
a) epidural puncture needle;
b) lumbar puncture needle;
c) combined anesthesia trocar;
d) nerve block puncture needle.
3.2 Labeling
3.2.1 Product model
The product model labeling is composed of product designation and classification code.
Product designation: Represent needle for anaesthesia by AN.
Classification code: Represent epidural puncture needle by E; represent lumbar
puncture needle by S; represent combined anesthesia trocar needle by E/S II; represent
nerve block puncture needle by N.
Note: For the lumbar puncture needles with Type II cutting edge, the cutting-edge type
code should be added after the classification code.
Example 1: Single-use needle for anaesthesia – epidural puncture needle:
AN-E
Example 2: Single-use needle for anaesthesia – combined anesthesia trocar of epidural
puncture needle and type II cutting edge lumbar puncture needle:
AN-E/S II
3.2.2 Product specifications
The product specification labeling is represented by the nominal outer diameter of the
needle tube × the length of the needle tube. Dimensions in millimeters.
