2.2 Conformation
The Gima Vital Signs Monitor is a product with modular design, consisting of an ECG module, NIBP module,
SpO
2
module, temperature module, main control unit, printer module (Optional), display panel, and power
supply module etc. and the related accessories for ECG, NIBP, SpO
2
and temperature measurement.
According to user requirement, you can order the device with different configuration to include the neces-
sary functions. Therefore, your monitor may not have all the monitoring functions and accessories.
1. The ECG/TEMP module detects the ECG signal through ECG cable/lead wires via electrodes. The tempe-
rature is measured through the temperature probe.
2. The SpO
2
module detects and calculates pulse rate and functional oxygen saturation (SpO
2
), and provides
plethysmogram and perfusion index.
3. The NIBP module measures blood pressure non-invasively with way of oscillometric technology, including
the diastolic, systolic and mean arterial pressure. The cuffs are designed for adult, pediatric and neonate
respectively.
4. The main control unit is in charge of LED and LCD display, keyboard input, data storage, printing and net-
working function.
