3 Classification and labeling
3.1 Classification
Single-use puncture set local anaesthesia (hereinafter referred to as anesthesia set) can
be divided into the following categories:
a) epidural anesthesia set;
b) lumbar anesthesia set;
c) combined epidural and lumbar anesthesia set;
d) nerve block set.
3.2 Labeling
3.2.1 Product model
The product model is composed of product designation and classification code.
Product designation: Represent anesthesia set by AS.
Classification code: Represent epidural anesthesia by E; represent lumbar anesthesia by
S; represent combined epidural and lumbar anesthesia by E/S II; represent nerve block
by N.
Note: For the anesthesia set equipped with a type II cutting edge lumbar puncture
needle, add the cutting edge type code “II” after the classification code.
Example 1: single-use puncture set local anaesthesia for epidural anesthesia
AS-E
Example 2: single-use puncture set local anaesthesia for combined anesthesia equipped
with epidural puncture needle and type II cutting edge lumbar puncture needle
AS-E/S II
3.2.2 The labeling of the single-use needle for anaesthesia provided in the anesthesia
set shall comply with the requirements in YY/T 0321.2.
3.3 Product configuration
After the catheter is connected to the catheter fitting, close the side hole at the front end
of the catheter, and apply a water pressure of 300 kPa to the conical hole of the fitting
for 30 s, and there shall be no water dripping from the connection.
5.3.11 Bending resistance
If it is indicated on the label of the single package that the catheter has bending
resistance, when testing according to Appendix E, the flow reduction rate after 180°
bending shall not exceed 10%.
5.3.12 Corrosion resistance of steel wire
If the catheter has a built-in steel wire, when testing according to GB/T 18457, there
shall be no traces of corrosion on the steel wire.
6 Chemical properties
6.1 Preparation method of test solution
See Appendix F for the preparation method of test solution.
6.2 Reducing substance (readily oxidizable substance)
When testing according to 5.2.2 in GB/T 14233.1-2008, the difference in the volume of
the potassium permanganate solution [c (KMnO4 = 0.002 mol/L] consumed by the test
solution and the blank solution shall not exceed 2.0 mL.
6.3 Metal ions
When testing according to 5.6.1 in GB/T 14233.1-2008, the color of the test solution
shall not exceed the standard control solution with a mass concentration ρ(Pb2+) = 5
μg/mL.
When using the atomic absorption spectrophotometry (AAS) in GB/T 14233.1-2008 or
an equivalent method for testing, the total content of barium, chromium, copper, lead
and tin in the test solution shall not exceed 1 μg/mL, and the content of cadmium shall
not exceed 0.1 μg/mL.
6.4 Limits for acidity and alkalinity
When testing according to 5.4.1 in GB/T 14233.1-2008, the difference of pH value
between the test solution and the same batch of blank solution shall not exceed 1.0.
6.5 Evaporation residue
When testing according to 5.5 in GB/T 14233.1-2008, the total content of evaporation
residue shall not exceed 5 mg.
6.6 Ultraviolet absorbance
When testing according to 5.7 of GB/T 14233.1-2008, within the wavelength range of
250 nm ~ 320 nm, the absorbance of the test solution shall not be greater than 0.1.
6.7 Residue of ethylene oxide
If the anesthesia set is sterilized by ethylene oxide, when testing according to Chapter
9 of GB/T 14233.1-2008, the total residual amount in single-use needles for anaesthesia,
