...
This is Part 2 of GB 8369.
This part is developed in accordance with the rules given in GB/T 1.1-2009.
This part has been redrafted and modified adoption of ISO 1135-5: 2015 Transfusion equipment for medical use — Part 5: Transfusion sets for single use with pressure infusion apparatus.
This part includes technical changes with respect to ISO 1135-5:2015. The clause and subclause concerned are identified by a vertical single line (|) located in the blank on its external margin of the page. These technical changes and reasons are listed in Annex F.
The following editorial changes have also been made in this part:
——the standard name has been modified to "Transfusion sets for single use — Part 2: With pressure infusion apparatus use";
——the informative Annex E has been added, which provides guidelines for the design and implementation of blood transfusion sets in China;
——the informative Annex F has been added, in which the technical changes and reasons are listed with respect to ISO 1135-5:2015.
Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights.
This part was proposed by and is under the jurisdiction of the National Medical Products Administration of the People’s Republic of China.
Transfusion sets for single use — Part 2: With pressure infusion apparatus use
1 Scope
This part of GB 8369 specifies requirements of material, physical, chemical and biological for single use transfusion sets for use with pressure infusion equipment capable of generating pressures up to 200 kPa (2 bar).
This part is applicable to single use blood transfusions sets for pressure transfusion equipment, which are used in conjunction with containers for blood and blood components and intravenous injection equipment.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
Note: For the purposes of Annex D, the following terms and definitions apply.
3.1
filling volume
VF
volume of tube during “pressure less” filling, respectively filling by gravity
Note 1: The tube remains unstressed.
Note 2: The filling volume is to be equated with the calculated volume of the tube.
3.2
storage volume
VS
tube volume during pressurization equal to filling volume, VF, plus bolus volume
VS=VF+VB
3.3
bolus volume
VB
increased tube volume during pressurization (VS) in comparison with the unstressed tube (VF)
Note: For illustration of the bolus volume, see Figure 1.

Keys:
1——patient;
2——occlusion;
3——tube;
4——bolus volume;
5——syringe pump.
