⚫Do not autoclave the syringe pump.
⚫Before using the internal battery, check the battery to ensure that sufficient power is available.
Recharge the battery if required.
⚫Liquid intrusion into the AC power socket or nurse call socket may cause short-circuit. Before
connecting the power cable, check if the connecting parts are dry. If liquid has spilled onto the
syringe pump, clean the pump with a dry cloth and then perform an inspection and maintenance.
⚫Use the maintenance parts and accessories provided by MEDCAPTAIN for replacement and
maintenance.
⚫Do not maintain or use the syringe pump in a flammable environment.
⚫High-frequency surgical equipment, mobile phones, wireless devices, and defibrillators may
cause interference on the syringe pump. Therefore, keep the syringe pump away from these
devices when using the pump.
⚫After maintenance, perform a safety test and clean the pump according to this manual.

d. Notes:
⚫The maximum voltage of the AC/DC power board may reach up to about 400 V. The workbench must be
insulated to avoid touch of the high-voltage circuit part. High voltage may cause electric shock and
personal injury.
⚫When performing a test with a multimeter or oscilloscope, note that the test probe must not short-circuit the
live part on the circuit board to avoid damage of the circuit board.
4.3 Main Control Board
a. Circuit description:
The HP-30 main board integrates the power system, main control system, communication circuit and
interface, motor drive control circuit, and pressure detection circuit. The specific functions are as follows:
(1) Power system: The power system consists of the battery and charging circuit, voltage conversion circuit,
and backup alarm circuit. The battery and charging circuit adopts the BQ24125 charging scheme of TI. By
default, quick charging mode is selected in power-off state and standard charging mode is selected in
working state. Charging is supported when AC input or DC input is available. In case of AC input, the
battery can be charged to 90% of the total capacity in 6 hours and fully charged in 8 hours. The voltage
conversion circuit converts the 15V power supply output by AC-DC, battery power supply, or external DC
power supply into the voltage required by the system. The voltage reduction circuit converts the power
supply into 5V and 3.3V to provide the CPU and system with proper power supply. The voltage increase
circuit converts the power supply into 24V for motor driving.
(2) Main control system: 3-CPU design, independent drive control, and dual-channel monitoring.
STM32F429IIT6 (M4 for short) is used for display driving, Ethernet drive control, and wireless module
communication. STM32F030RCT6 (M0 for short) is used for control of motor drive chip, control of
audible and visual alarm, and signal detection. STM32F030C8T6 (M0S for short) is used for signal
detection and control of motor power supply.
(3) Interface circuit: USB2.0 interface implements the RS232 interface function. In addition, it can implement
communication with the HP-80 infusion workstation and connection to the barcode scanner for scanning of
patient information, for example, scanning of medical record number and hospital number. The USB3.0
interface is used to connect to the nurse call system for implementing the nurse call function.
(4) Audible alarm: The beeper and loudspeaker alarm circuit is used to implement the audible alarm function.

Hardware Description
19
(5) Motor drive control: The motor drive chip manufactured by TRINAMIC is used, which supports 24V/2A
drive output. In addition, the stepper motor supports a subdivision of up to 256, ensuring infusion accuracy
and stability at low infusion rate. The SPI communication interface is used for connection to M0. Motor
start/stop, motor rotation speed, and motor acceleration/deceleration are all controlled by SPI signals.
(6) Occlusion pressure detection circuit: Used to test the occlusion pressure.
(7) WiFi function: WiFi circuit and protocol are used for communication with the nurse station, implementing
output of infusion data.
(8) Wired network function: Wired network is used for communication with the nurse station, implementing
output of infusion data.

4.5 HP-30 Clutch Board
b. Circuit description:
The main functions are as follows:
(1) Pressure sensor signal processing: This board inputs, amplifies, and filters the signal of the pressure
sensor and then outputs the signal to the main board.
(2) In addition, this board detects the drive sheet position, clutch signal, angle sensor signal, and claw
motor signal and transmits the detected position information and signals to the main board through
a connection cable.
c. Main test point:
No.
