SECTION 4 - PRODUCT OVERVIEW
Sperm Preparaon Reader
RI Witness is a system which operates within an assisted reproducon (AR) clinic seng and provides
a method of idenfying human samples throughout an AR cycle (from egg and sperm collecon to
embryo transfer). The system is intended to minimise the risks associated with tradional/manual
double-checking and provides the essenal 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 soware components, which can be
congured depending on the treatment acvies, number of AR cycles conducted, size and layout of
the AR clinic.
RFID technology provides the means of idenfying 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 idener. The unique idener is linked to a paent/couple
(specic 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 identy and status is conrmed on-screen. If containers holding samples
of incompable origin come into contact at any stage of this process, the system acvates an alarm and
prompts the clinician to respond.
This manual refers only to the Sperm Preparaon Reader.
Other devices in the RI Witness range have their own manuals, as does the soware.
