SECTION 4 - PRODUCT OVERVIEW
Sperm Preparation Reader
RI Witness is a system which operates within an assisted reproduction (AR) clinic setting and
provides a method of identifying human samples throughout an AR cycle (from egg and sperm
collection to embryo transfer). The system is intended to minimise the risks associated with
traditional/manual double-checking and provides the essential controls necessary to ensure
eggs, sperm and embryos are correctly matched and treated during the AR process.
The RI Witness system comprises hardware, rmware and software components, which can be
congured depending on the treatment activities, number of AR cycles conducted, size and
layout of the AR clinic.
RFID technology provides the means of identifying the containers (dishes, tubes) in which eggs,
sperm and embryos are transferred and stored. The containers are labelled by a clinician with a
special RFID tag which has been assigned a unique identier. The unique identier is linked to
a patient/couple (specic parentage).
As samples are processed as part of an AR cycle, RFID readers (both heated and non-heated)
read the tags on the container and their identity and status is conrmed on-screen. If containers
holding samples of incompatible origin come into contact at any stage of this process, the
system activates an alarm and prompts the clinician to respond.
This manual refers only to the Sperm Preparation Reader.
Other devices in the RI Witness range have their own manuals, as does the software.
