2 Princi ple of Design 2.1 Overview This infusion pump is intended for accurate continuous infusion of the drug to a single elderly person, child or newborn baby patient.
2.2 System Breakdow n The system is broken down by mechanical components, hardware and software. The composition diagram is as below:
-5-
The system card connection diagram is as below:
-6-
2.3 Hardware Configuration Schematic Diagram:
The system core is mainboard and power board. LCD display and its power source are controlled by the mainboard. The measuring and status information of each module is processed by the power board before sending to the mainboard. Finally under the control of mainboard, the information is displayed on the screen. The mainboard is also assigned to control the buzzer and status indicator. All modules are powered by the power board. The power board is also assigned for driving of the motor, measuring of each sensor and processing of status information.
-7-
2.3.1 Mainboard The mainboard serves for information integration of the whole system. It is designed to control the LCD and the functions such as keypad input, buzzer sound and parameter saving.
2.3.1.1 Schematic Diagram
2.3.1.2 Function Introduction The mainboard communicates with the power board or ZIGBEE wireless module on power board via the extended serial port of logic gate circuit. The mainboard provides the display information to LCD and detects the key operation, realizing the user interface; The mainboard controls the buzzer for its alarm sound as well as the key stroke sound. The mainboard controls the run indicator via adaption from power board. SRAM supports the temporary storage of data and run of the program. EEPROM is used as the memory on the machine.
-8-
2.3.2 Pump B od y The pump device is the provider of dynamic force to the whole system and it is the source of power to deliver the liquid. During operation, the stepper motor drives the cam shaft to rotate, so that the pump impeller reciprocates up and down by a specific sequence and rule as waves to squeeze the intravenous infusion pipe, pushing the liquid in the infusion pipe to flow at a preset speed
-9-
2.3.3 Power Bo ard The power board receives the function information from air bubble pressure sensor and then sends it to the mainboard. It also drives the stepper motor to run according to the information from the mainboard. The power board is also assigned to convert the power supply (from city grid and battery) into the power required for each board. It also supports battery charging.
2.3.3.1 Schematic Diagram
2.3.3.2 Function Introduction When AC power is input to the power board, 12V DC voltage is first obtained via a safety certified power module. This DC voltage is used as the main input for DC/DC conversion and recharging circuit. In this case, we can not only recharge the lithium battery, but also obtain 5V, 3.3V and 18.9V DV voltage via conversion by 5V DC/DC, 3.3V LDO and 18.9V DC/DC circuit. Except the power supply functions, the MCU on power board is also assigned for processing the measurement and status information from the sensors before sending it to the mainboard. It also controls the run of stepper motor according to the commands from the mainboard.
-10-
2.3.4 Air B ubbl e Pressur e Board The air bubble pressure board provides the functions to detect the air bubble, occlusion and door opening. It detects the air bubble by checking the attenuation of ultrasonic wave in different materials, while it detects the occlusion by using the pressure sensor. Schematic Diagram
2.3.4.1 Function Introduction The central processor on ultrasonic pressure board will process the signals from the ultrasonic circuit and door opening sensor, and then send them to MCU on mainboard. The pressure amplification circuit will amplify the weak voltage signals from pressure sensor before sending them to the power board.
2.3.5 Door Opening Detection Board A micro switch is placed on the door opening detection board. Any change in handle status can affect the closing of micro switch. In this case, we can know the status of handle from detecting the closing state of the micro switch.
-11-
2.3.6 Dro p Senso r
The drop sensor is fixed on the liquid filter. Measuring method: When the liquid droplet drips down through the filter, it will impede the receiving of infrared light in the sensor. By applying the pulse signals generated from the infrared light of different intensity, the dripping frequency of liquid drops is exchanged into the flow rate of infusion. And by using this signal for feedback of actual infusion condition of the pump, we can detect if there is any liquid leakage.
-12-
