DESCRIPTION
•The Blood and Infusion Warmer FT2800 can be used in all applications in which
hypothermia of the patient through cold transfusions and infusion solutions is to be
prevented. It is consisted of the main body, 2 flexible warming profiles, fastening unit and
power cable. The main body has two independent symmetrical control units. During the
operation, the infusion tube is inserted into the warming profile. The intelligent
micro-computer processing control system works separately and automatically to heat up
the two profiles homogeneously and continually adjusts heating state. At the same time,
the heat is transferred into the flowing liquid in the tubing placed in the profile, to rise the
temperature of the liquid. It is equipped with double independent temperature protection
systems to ensure the safety of use.
•The temperature of warming profile can be set between 33°C and 41°C in steps of 0.1°C
and is displayed on the LED screen. The device can memorize the last set temperature
automatically.
•The alarm and self-test functions for over-temperature and under-temperature
incorporated into the device assures safe operation.
•A standard infusion tubing (5.0mm in O.D and 1.4m in length) may be used in

conjunction with the FT2800.
•The temperature shown in the display corresponds to the temperature of the warming
profile.
•The temperature of the fluid to be heated that is reached at the end of the warming section
depends on various factors, such as, the fluid's input temperature, the flow rate, the set
temperature, the ambient temperature, etc.

Applied part
The warming profile which is applied part of the medical device is type "BF". The electrical
conductors in the warming profile have been insulated from the other parts of the medical
device to such a degree that no current higher than the allowable PATIENT LEAKAGE
CURRENT flows if an unintended voltage originating from an external source is connected to
the PATIENT, and thereby applied between the PATIENT CONNECTION and earth.
The warming profile is defibrillation-protected and supplied with safety extra-low voltage.

CONTRAINDICATION
It is forbidden to be used on the severe cardiopulmonary dysfunction patients.
The device may not be used to warm living organisms, objects.
It is forbidden to use for heating the drug liquid which the normal effect would be influenced
after heating.

WARNINGS
▪If the over-temperature alarm is triggered, the supply of liquid to the patient must be
immediately stopped by disconnecting the connection tube to the patient. The medium
being used in the device must no longer be administered to the patient.
▪In the event of any suspected malfunction while in operation, the supply of liquid to the
patient must be immediately stopped by disconnecting the connection tube to the patient.
The medium being used in the device must no longer be administered to the patient.
Switch off the heating or unplug the mains plug.
▪The device must not be used in rooms subject to explosion hazard.
▪The device may only be fastened to infusion stands or tripods which are suitable due to
their stability and load capacity.
▪The device must not be immersed in liquids or sterilized with steam or by thermochemical
methods.
▪All extraneous influences such as radiation, electromagnetic interference or high
temperature are to be kept to minimum.
