General specification
1 Scope
This Standard specifies the general technical conditions for the blood flow products for single use.
This Standard applies to the blood path AND its connected subsidiary pipelines which are mainly made from PVC, including the products composed of fluid path AND pressure monitoring pipeline, etc. (abbreviated as blood path). The relevant provisions of this Standard take precedence over this Standard. 2 Normative references
The provisions in following documents become the provisions of this Standard through reference in this Standard. For the dated references, the subsequent amendments (excluding corrections) or revisions do not apply to this Standard; however, parties who reach an agreement based on this Standard are
encouraged to study if the latest versions of these documents are applicable. For undated references, the latest edition of the referenced document applies. GB/T 1962 Conical fittings with a 6% (Luer) taper for syringes, needles and certain other medical equipment

3.2.6 Color code
When the blood path is divided into arterial blood path and venous blood path, within 100mm from the pipeline end, it shall have apparent color identifications. It is preferable for the arterial blood path to use red color, AND the venous blood path to use blue color.
3.2.7 6% Luer taper
The 6% Luer taper between blood paths shall comply with the requirements of GB/T 1962.
3.2.8 Blood filter
The mesh of the blood AND blood component filters along the blood path shall be uniform, AND the effective filtration area shall be not less than 10cm2. When conducting test in accordance with Appendix C, the filtration rate shall be not less than 80%.
3.2.9 Switch
3.2.9.1 As for the blood path switch selection, GIVE priority to non-contact tube clamp or flow regulator. Its performance shall be reliable.
3.2.9.2 The blood-contacted blood path change-over switch (such as single valve three way switch, double valve four way switch, and triple valve five way switch, etc.) shall have clear switching state indication. Its performance shall be reliable.
3.2.10 Air filter
If there is admission line along the blood path, then it shall have air filter which can prevent outside microorganisms and dust from entering into the blood path. When conducting test in accordance with Appendix D, the air filter?€?s filtration rate for 0.5??m above particles in air shall be not less than 90%.
3.2.11 Appearance
The hose along the blood path shall be plasticized uniformly, have no kinks, AND its transparency shall guarantee that using normal vision or corrected vision can find the bubbles from the blood path.
3.3 Chemical properties
The test solution prepared in accordance with Appendix E shall comply with the requirements of 3.3.1 to 3.3.6.
Appendix A
(Normative)
Particulate content test method
A.1 Principle
This method is, by flushing the blood path internal liquid passage surface AND collecting the particles from the passage surface flushing solution, to count the particle amount, in order to evaluate such contamination.
A.2 Test instrument
A.2.1 Dedicated particle counter. it has a stirring system AND one sampling volume is 100mL; it can simultaneously conduct counting for the particles of 15??m ~ 25??m OR greater than 25??m.
A.2.2 Flushing liquid. it shall comply with the particle counter requirements, AND pass the new 0.45??m microporous membrane for filtration.
A.3 Step
Note. The test shall avoid environmental pollution.
A.3.1 Eluent preparation
Using the flushing liquid at the proportion of 1mL per square centimeter internal surface area, RINSE the blood path internal surface. This method shall be designed that, each unit area inside of the pipeline directly or indirectly contacting the blood or blood component shall be able to subject to the same volume of flushing liquid (if along the blood path there is vessel shaped part, then this blood path section shall be correspondingly added of the flushing liquid of this vessel volume). The effluent is collected into a clean vessel, which is the eluent.
A.3.2 Particle inspection
PIPETTE 200mL of eluent into the sample cup of the particle counter; USE the particle counter to count the particle in the 100mL of eluent.
A.4 Results expression
USE the counted value of the counter to divide 100 to obtain the particle content, in the unit of piece per millilitre. USE blank solution to correct it. Appendix B
(Normative)
Injection part self-sealing test method
PLACE the injection part level AND unstressed; FILL water into the blood path and AVOID inclusion of bubbles; LEAD in the pressure 20kPa (200 mbar)
above the atmospheric pressure; USE 0.6mm outer diameter needle which
complies with GB 15811 to pierce the puncture area of the injection part; after piercing in for 15s, PULL out the needle and quickly make the pierced location dry. OBSERVE it for 1 min to see whether there is leakage.
NOTE. If there are injection parts of other design types, they shall, in accordance with the instructions provided by the manufacturer, pierce the injection part to conduct test.

C.3 Step
PREPARE anti-coagulated isotype ABO blood group human body whole blood; STORE it for at least 2 weeks; from its vessel and through a pore diameter 2250??m coarse strainer, INJECT the blood into a 4L vessel; MAKE the blood be thoroughly mixed.
LET the blood in the vessel flow under gravity through the filtration material (800mL for each); MAKE the excessive blood on the filter flow off; in the 60??C??2??C oven under the pressure of 0.65kPa (6.5 mbar), MAKE the filtration material be dried to basic constant weight.
C.3.1 Method A (applicable to the filtration material)
From the standard filtration material and the test filtration material, respectively CUT two diameter 40mm round materials. During test, FIX each filtration material to the test device at locations where the entire surface of the filtration material can be covered by blood.
C.3.2 Method B (applicable to the filter assembly)
The standard filter assembly shall have a standard filtration material which is bottom end sealed AND of area 32cm2. The filtration material shall be installed in a plastic filter cone which has an outlet at bottom. The filter cone outlet is a standard dropper from which 20 drops of distilled water equals to 1mL; AND the inlet tube extends into the filter cone. Figure C.1 shows the applicable standard filter assembly. The test steps are same as those in chapter C.3. Note. Method A and Method B are optional.
