Service
1.2.1
General Responsibility for the safe functioning of the equipment reverts to the owner or user in all cases in which service or repair has been done by a non-professional or by persons who are not employed by or authorized by MAQUET, and when the equipment is used for other than its intended purpose. In addition to the Important information given here and in the related documents (e. g. in the User's Manual), always pay attention to applicable local and national regulations. Record all User options and restore them if altered during service. If unit is used on HL 20 then record mode setting before removing unit from console. Refer to Rotaflow User’s Manual, chapter 4. Operation, for a description of available options.
1.2.2
Hazard notices WARNING
Service by unqualified service engineer! Only service engineers trained and authorized by MAQUET shall be permitted to perform installation, service or maintenance of the ROTAFLOW. Service by an unqualified service engineer may result in injury to the technician, the patient, other personnel or may cause damage to the equipment.
WARNING
Disassembling or assembling! Before disassembling or assembling of the ROTAFLOW, make sure that the: – On/Off Switch is set to Off. – Mains power cable is disconnected. – Backup batteries are disconnected. – The unit is cleaned according to instructions in the User's Manual.

WARNING
CAUTION
1. Important
Energized electrical components! With power supply connected to the ROTAFLOW, there are energized electrical components inside the unit. All personnel must exercise extreme caution if fault tracing or adjustments are performed with power supply connected.
Leakage currents! When the unit is used together with other medical machines the total of the leakage currents must be checked.
ESD sensitive components! When handling ESD-sensitive devices, established procedures must be observed to prevent damage. When working with ESD sensitive components, always use a grounded wristband and a grounded work surface. Adequate service tools must always be used.
1.2.3
Preventive maintenance The ROTAFLOW must be serviced at regular intervals by personnel trained and authorized by MAQUET. Refer to chapter “7 Preventive maintenance”. Any maintenance or service must be noted in a logbook provided.
1.2.4
Functional check After any installation, maintenance or service intervention in the ROTAFLOW, perform a Function check according to instructions in chapter “5 Service procedures”.
1.2.5
To the responsible service personnel The contents of this document are not binding. If any significant difference is found between the product and this document, please contact MAQUET for further information. We reserve the right to modify products without amending this document or advising the user. Only personnel trained and authorized by MAQUET shall be permitted to perform installation, service or maintenance of the ROTAFLOW. Only MAQUET genuine spare parts must be used. PC boards (spare parts) must always be kept in a package for sensitive electronic devices. MAQUET will not otherwise assume responsibility for the materials used, the work performed or any possible consequences of same. Components on PC boards must not be replaced. The PC board is the only available spare part. The information in this manual regarding components on the PC boards is intended for troubleshooting only.

Introduction
2.1
General The ROTAFLOW is a centrifugal pump system intended to be used in an extracorporal perfusion circuit to pump blood during cardiopulmonary bypass procedures. It can be used as a fully independent stand-alone unit or as a part of the Heart-Lung Machine console JOSTRA HL 20. Some features of the ROTAFLOW System: • The flow can be kept constant, independent of the pressure. • Air bubbles in the circuit can be detected and prevented from entering the patient. • A too low liquid (blood) level in a reservoir can be detected and regulated (optional). • The system can run on the battery backup. • A more physiologically optimized pulsatile pumping is possible, internally triggered or controlled by the patient’s own ECG. • The pressure can be monitored and regulated when used with an HL 20. • Most functions needed during an operation can be controlled from the system control panel. Useful signals and data are displayed. • A complete perfusion protocol can be recorded on-line or off-line with JOCAP XL for later analysis and printout.

System components
ROTAFLOW Console RFC
ROTAFLOW Drive Unit RFD
The RFC is the systems control module with triple power supply; mains, internal back-up battery or HL 20 if connected.
The RFD is the drive unit for the Centrifugal Pump. This unit also incorporates flow sensor and bubble detection. The hydraulic swivel-joint bracket assures ideal positioning of the RFD.
ROTAFLOW Emergency Drive RFE
ROTAFLOW Centrifugal Pump RF
The RFE is an emergency drive for the Centrifugal Pump.
The RF is the disposable pump head intended for the RFD and RFE.
When operated, LEDs (speed indicators) shows RPM.
Due to the combination of mechanical and magnetic bearing, the mechanical friction potential clotting zones are significantly reduced. The centrifugal pump’s minimal priming volume of 32 ml considerably reduces hemodilution.
