1.6 Product Description
The DigiPump SR7x syringe pump contains the following components:
1. The microcomputer system: the “brain” of the whole system, that control and manage the whole
system and process the detected signals. Two single-chip Microcontrolers are used for mutual
backup copy and supervision. When one Microcontroler goes wrong, the other one will give an
immediate warning signal and cut the power of the host computer, which will then stop
completely, thus ensuring patient’s safety.
2. The Pump Device: the “heart” of the whole system and the main driving force of the infusion.
Driven by stepper motor, the lead screw moves the infusion piston forward.
3. The Sensor System: various kinds of sensors, such as displacement sensor (detecting liquid flow
rate and flow volume), pressure sensor (detecting occlusion), etc. They supply corresponding
signals which will, after being amplified, be sent over to the computer for signal processing.
4. The alarm device: after the signal given by the sensor is processed by the microcomputer, an
alarm control signal triggers the corresponding audio and visual alarm bringing operator’s
attention for right action. There are mainly two kinds of alarms: Visual alarm (LED) + Alarm
Message in the screen and sound alarm (buzzer).
5. The Keypad and Display device: It is used to set infusion parameters, such as infusion volume
and infusion rate. It displays various parameters and the current operation progress on the
LCD display.
6. The rechargeable battery: provides internal power for the pump when there is no AC power.
