Section 9.5

9.5   Generic protocol for the evaluation of apheresis equipment

This protocol sets out the minimum requirements for new apheresis equipment and, in a generic form, the mechanism for assessing acceptability of the equipment hardware, the software and the associated apheresis sets. The specific validation or trial of apheresis collections from new equipment is covered in Section 9.6. Novel components, as defined in Section 9.1, produced as a result of new equipment will be assessed as detailed in other sections of this chapter.

Minimum requirements

General

Equipment should be CE-marked or the Blood Service should participate to facilitate CE Marking.

Manufacturers must comply with Good Automated Manufacturing Practice (GAMP).

Equipment hardware

Equipment should contain the following:

manual override system

blood flow monitor

in-line air detector

integral blood filter

anticoagulant flow indicator

collection volume preset device

visual audible alarm for procedure completion

automatic standby mode for power failure

power up self-check to include all critical safety and operational procedures.

Equipment software

Software should provide parameters for

accepted total blood volume calculation algorithm

accepted citrate reinfusion rate calculation algorithm

fixed upper limit citrate reinfusion (see Chapter 6)

programmable upper limit total collection volume

must not exceed predetermined fluid reinfusion limits (e.g. citrate, saline)

alarm and prevent use of incorrect set (incongruent) for programmed procedure

prevent procedure where predicted post-collection parameters fall outside programmable safety limits as defined in Chapter 6

for other measures see Chapter 6.

Apheresis sets

Apheresis sets should have

closed system

visual system to minimize risk of transposition of fluid lines

microbial filter on 'spiked' lines

diversion line and pouch for sampling

consideration should be given to the incorporation of a pouch on the final pack to facilitate bacterial contamination testing

for other measures see Chapter 6.

The overall mechanism for equipment acceptance is given in Table 9.6 for reference. Validation, installation qualification, operational qualification and performance qualification would be defined by the Blood Service, taking account of the advice within these Guidelines.
