Mindray Accutorr 7 Service Manual

2-6
AC/DC Power Module
The AC/DC power board transforms the input AC into DC power, which is the power source
for all voltages in the equipment.
Power Management
and Interface Board
The power management and interface board provides the following functions:
 Charge and discharge of battery and charge detection;
 DC/DC conversion: outputs 12V and 5V DC power;
 Control over power on/off key and AC, BAT indicator;
 Communication transmission among parameter modules;
 Providing isolation power for SpO
2
module; and,
 Providing external connectors
, filter and protection for these connectors.
Recorder
The recorder receives data from the main board and sends them to the thermal printhead
for printing.
NIBP Module
The NIBP module consists of blood pressure measurement board and pump and valve
assembly, providing measurement acquisition of blood pressure data. The main functions of
the NIBP module are:
 NIBP measurement; and,
 Data exchange with the main board.
SpO
2
Board
The SpO
2
board collects SpO
2
signals, processes SpO
2
algorithm and sends measurement
results to the main board. The power management interface board provides isolation power
for it.
CO
2
Module (Only Available for Accutorr 7)
CO
2
monitoring is a continuous, non-invasive technique for determining the
concentration of CO
2
in the patient’ airway by measuring the absorption of infrared (IR) light
of specific wavelengths. The main functions of the CO
2
module are:
 Provides a CO
2
waveform, and EtCO2, FiCO
2
, awRR measurement; and
 Data exchange with the main board through the serial ports.
2.7 External Module
An external Temp module can be attached to the monitor.
The independently developed Mindray Temperature module consists of an isolation power
board, Temperature measurement board, and probes. The Temperature measurement
board collects Temperature signals, processes algorithm and sends measurement results to
the main board.
