3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
Annex A
Test method for determining urethral catheter strength
A.1 Principle
Urethral catheters with balloon may be used in situ for long periods of time.
Therefore, for urethral catheters with balloon, the urethral catheter is immersed
in simulated urine for 14 days before the test. For urethral catheters without
balloon, this step may be omitted. A tension is applied to the junction between
the tip and the shaft of the urethral catheter. For urethral catheters with side
holes, tension is applied to the holes; for catheters without side holes, tension
is applied between the shaft and the drainage conical interface. After remove
the tension, check the urethral catheter for signs of destruction.
A.2 Reagents
A.2.1 Simulated urine may use either of the following two formulas.
a) Simulated urine consists of the following components (pH is about 6.6).
The reagents are analytical reagents.
Urea 25.0 g
Sodium chloride 9.0 g
Anhydrous disodium phosphate 2.5 g
Ammonium chloride 3.0 g
Anhydrous potassium dihydrogen phosphate 2.5 g
Creatinine 2.0 g
Sodium sulfite, anhydrous 3.0 g
Distilled water dilute to 1.0 L
Warning. This solution helps the growth of microorganisms. At the end of
the tests described in A.3 and C.3, there is likely to be a large amount of
microorganisms. These tests shall be carried out by trained personnel.
Appropriate preventive measures shall be taken when handling the
soaked urethral catheter and discarding the contaminated solution.
b) Simulated urine consists of the following components (pH is about 5.5 ~
Annex B
Test method for determining the assembly
separation force of drainage conical interface
B.1 Principle
CONNECT the specified test connector to the drainage conical interface of the
urethral catheter; APPLY an axial tension; CHECK if the connection is
B.2 Instruments
B.2.1 Test connector, made of rigid material, dimensions are shown in Figure
B.2.2 Fixture or similar devices, for suspending urethral catheters.
B.2.3 Connection device for weights and test connector. For urethral
catheters with a specification of 3.3 mm or less, the total mass of the connection
device and the weight is 0.75 kg; for urethral catheters with a specification
greater than 3.3 mm, the total mass of the connection device and the weight is
1 kg.
B.2.4 Timer.
B.3 Procedure
The test is performed at (23 ± 2) °C.
Allow the urethral catheter's drainage conical interface and connector (B.2.1)
to clean and dry.
PLUG the connector into the drainage conical interface to a depth of 10 mm or
more (i.e., reach or exceed the marking on the connector).
SELECT a point from the connection between the drainage conical interface
and the shaft, CLAMP with a clamp (B.2.2), SUSPEND the urethral catheter
(see Figure B.1b)].
HOLD the weight (B.2.3), on the drain cone of the urethral catheter and gently
place the weight down until it is suspended from the urethral catheter. Hold it
for 1 min and observe.
RECORD whether the test connector is separated from the conical interface.
in the range, it shall be filled up to the maximum capacity.
The urethral catheter is immersed in freshly prepared simulated urine (C.2.2)
and placed in the water bath (C.3.3) controlled at (37 ± 2) °C, to completely
immerse the tip and the balloon.
REMOVE the urethral catheter after being immersed for 14 days in simulated
urine; RINSE with tap water and allow it to dry; PLACE the urethral catheter at
a temperature of (23 ± 2) °C.
PLACE the urethral catheter in the suspension device (C.3.1) with the tip facing
up; ALLOW the balloon to sit in the counterbore, and the shaft to pass through
the hole in the plate.
NOTE. For suspension device that cannot be separated from the middle, to facilitate the
insertion of the urethral catheter into the suspension device, it may cut the conical interface if
necessary, or fill the balloon after passing through the urethral catheter.
SELECT the weight suitable for the test urethral catheter according to Table
HOLD the weight, CONNECT it to the shaft or conical interface of the urethral
catheter. PUT the weights down lightly until it is free to suspend on the urethral
catheter, KEEP for 1 min.
During the weight suspension, visually inspect the urethral catheter.
a) Whether the drain hole (if any) is affected by the balloon.
b) Whether the balloon leaks.
C.5 Test report
The test report shall include the following information.
a) urethral catheter identification;
b) whether the drain hole is affected by the balloon;
c) whether the balloon leaks.
Annex D
Test method for determining leakage
and/or function of filling cavity and balloon retraction
D.1 Principle
The balloon and filling cavity of the urethral catheter are filled with water and
immersed in simulated urine for 14 days. The water in the balloon is released
under gravity. The capacity of the recovered liquid is measured.
D.2 Instruments and reagents
D.2.1 Fixture or similar devices, for clamping the tip of the urethral catheter,
suspending the urethral catheter.
D.2.2 6 % (Luer) outer conical fitting, in accordance with GB/T 1962.1, such as
a piston-remo......
