It shall comply with GB 8368.
8.3 Biological compatibility
When evaluating the biological compatibility of check valves, it shall be performed
according to GB/T 16886.1.
9 Packaging
It shall comply with GB 8368.
10 Labels
10.1 Single packages
The single package containers shall indicating the following information.
a) Text description of the contents;
b) The graphic symbols given in YY 0466, indicating that the check valve is sterile;
c) The check valve has no pyrogen or the check valve has no bacterial endotoxin;
d) The check valve is for single use only, or equivalent texts, or graphic symbols
that comply with YY 0466;
e) Instructions for use, including warnings, such as checking whether the
protective cover is off;
f) The lot number starts with the word "batch (LOT)", or adopts the graphic symbols
given in YY 0466;
g) The words of "Safe for pressure infusion devices"1;
h) The identification marks that comply with Chapter 4 (such as YY 0585.4/ ISO
i) The letter "P" that represents the pressure, its size shall be bigger than the
1 The name and type of pressure feed infusion sets shall be given by the manufacturer.
At (23 ± 2)°C and (40 ± 2)°C respectively, SUBJECT the check valve to a water
pressure of 200kPa in the counterflow direction for 15min. Check for leakage through
the check valve.
A.6 Volumetric flow rate
CONNECT the check valve with the infusion set, according to the specifications of GB
NOTE. If the requirements of 6.6 are not met, the infusion sets without the check valve shall be
A.7 Blocking performance
It shall perform two tests. one with distilled water, one with 40% glucose.
When performing tests, the check valve shall be performed at least three tests under
the states of horizontal position, vertical position and reverse vertical position.
The check valve shall be connected to the test system shown in Figure A.1.
For the check valve that is permanently installed in the fluid line, the pipe shall be cut
off, a three-way switch with the tube shall be installed. It can also decline the liquid
level of the test solution in the pipe, and make a liquid level mark.
FILL the entire system with the required test solution, avoid air bubbles, and then
perform the following steps.
a) Switch position 1
If necessary, use switch position 1 to stabilize the feed rate2 of the pump.
b) Switch position 2
KEEP the switch of the infusion set pipe on, there shall be a flow through the
check valve for 2min.
c) Switch position 3
It shall observe.
- the pressure of the pump and the check valve pipe indicated on the pressure
gauge is rising;
- the water level in the tube is moving toward the outlet end and the fluid drops
2 It is recommended to apply pressure to the sy......
