1-1
1.1.2 WARNING WARNING
Device, cables and accessories must be inspected before use to guarantee their normal and safe operation.
This equipment can only be connected to the socket with ground protection. Please adopt a rechargeable battery instead of the socket as the power supply if the socket is not provided with a ground lead.
To prevent fire or explosion, do not operate the equipment in the presence of anesthetic, flammable or explosive materials.
Do not open the equipment casing as there is the impending danger of electric shock. Equipment maintenance and upgrades must be carried out by maintenance technicians whom are trained and licensed by the manufacturer. Moreover, the process must be done only after the AC power supply is disconnected. Maintenance carried out by individuals non-affiliated to the manufacturer or by non-licensed personnel may affect the safety, performance and function of the product.
When used with electrosurgery equipment, the safety of patients should be ensured.
The patient's clinical condition and the working condition of the syringe pump must be monitored carefully, and the alarm volume and alarm levels need to be set according to the actual needs. Operation and performance relying solely on the auditory alarm system alone is not sufficient, and setting the alarm at a low volume may endanger the patient. If the alarm volume is less than the surroundings volume, which can further lead to operators identify alarm mistakenly.
Please carefully install the power line and cables with various accessories to prevent the patient from choking or suffocation caused by entanglement of the cables or by electrical disturbance.
The packaging materials must be disposed of in compliance with local laws and regulations or the hospital policy on waste management. They must be kept out of the reach of children.
Infusion cannula knots, filter coagulation and occlusions arising from needle insertion can cause the pressure inside the syringe to rise during infusion. When this occurs, removing the occlusion can cause excessive liquid to be infused into the patient, so appropriate measures should be taken.
The pump should not be placed more than 100cm above or below the level of the patient’s heart. The smaller the height difference between the pump, the more accurate the pressure test in the infusion cannula will 1-2
be.
This equipment has to be used with professional medical consumables, and its accuracy cannot be guaranteed when it is used with a syringe which is a non-standard consumable or a consumable without calibration, please contact the company for calibration service.
Do not touch the patient when connecting the peripheral equipment via the input/output signal ports to prevent patient leakage current from exceeding the requirements specified by the standard.
In the process of defibrillation, do not touch patient and other non-defibrillation equipments to prevent electric shock damage, and defibrillation will not affect the basic performance (such as infusion accuracy, alarm and signal transmission) of the pump.
1.1.3 CAUTION CAUTION
Use the accessories specified in this Operator’s Manual to guarantee the patient’s safety. When equipment and the accessories exceed their recommended service life, they must be disposed of in accordance with local statutes or hospital regulations. Electromagnetic fields may affect equipment performance. This makes it necessary for other equipment used in the vicinity of the pump to meet EMC standards. Mobile phones, X ray and MRI equipment are all potential interference sources because of their high-intensity electromagnetic radiation. Before the equipment is connected to the power supply, check that the voltage and frequency of the power supply match the specifications on the label or in this Operator’s Manual. Please install and carry the equipment correctly to protect the equipment from damage from drops, impacts, violent shaking or other external mechanical forces. Disposable accessories must be disposed of after use in accordance with the relevant hospital regulations. Avoid direct sunshine, high temperatures and dampness. Check the built-in battery before use to make sure it has sufficient power. Recharge the battery if necessary. The syringe with the luer taper is recommended for use, which can effectively prevent patients from under current caused by the occurrence of the cannula to slip out when under tension. 1-3

2.3.1 Core control board SP1 core control board consists of three sections, namely power, main control and monitoring sections. Power section includes AC/DC conversion module, switch control circuit, DC power conversion circuit, standby sound-light alarm circuit, and battery charge-discharge management circuit. AC/DC conversion module converts AC 100-240VAC input, 50/60Hz to DC 15V output. Switch control circuit combines inputs from AC/DC, external DC and internal battery into VBUS, with AC/DC and external DC having higher priority than internal battery; Switch signal then converts VBUS to VPP as output. While VBUS is not controlled by switch signal, VPP output is controlled by switch signal. VPC is bucked to VCCB (5V) via LDO circuit (U9 ZSR500GTA)and VCCB is bucked to VBB (3.3V) via LDO circuit (U13 SPX5205); VPP is bucked to VCC (5V) via Buck circuit (U11 TPS5410D) ; VCC is bucked to VDD (3.3V) via LDO circuit (U12 SPX1117M3) ; VPP is boosted to VMM (+18.9V) via Boost circuit (U6TPS61175PWP) . Main control CPU is responsible for switch control and motor power-down protection under a single fault, while monitoring CPU is responsible for battery charge status monitoring, various module power status detection, battery indicator control and communication with the main control module CPU via serial ports. After triggered by the switch key from the key board, main control CPU and monitoring CPU simultaneously output the ON locking signal and the module power enabling signal to enable the output of VCC, VDD and VMM, so that the entire system is powered on.To turn off the equipment normally, after detecting the OFF signal, the main control CPU notifies the monitoring CPU to cancel the ON locking signal via serial ports, and finally the equipment is turned off by the main control CPU. Battery charge-discharge management circuit uses BQ24103RHLR, with OFF- and ON-mode charging current designed for 650±50 mA (single battery charging time is not more than 6h, while dule battery charging time is not more than 12h); the battery is designed to be fully charged at the voltage of 8.1 ± 0.2 V. When the battery voltage is too low and the AC power supply and external DC power supply are disconnected, the standby sound-light alarm circuit triggers the buzzer to ring at the frequency of 2.73 Hz ± 0.5 V, and simultaneously drives the red alarm light to be always on.
2-6
When the monitoring CPU detects unusual power of the VDD or abnormal communication with the main control module CPU, the buzzer rings and the stepper motor's power is then shut down.

3.4 Calibration 3.4.1 Syringe calibration Syringe Calibration purpose Syringe calibration is to increase the infusion accuracy, and then to calibrate the non-built-in brand syringes. The parameters to be calibrated include the syringe outer diameter, the full-range length and the emptying location. When delivery, the data of the custom brands is null; if a custom syringe brand is not calibrated, such brand will not be shown in the list of syringe brands when use. The syringe in the syringe pump requires no daily calibration. However, calibration is required when the syringe pump is used for the first time, is replaced with a new syringe brand or when you doubt that the deviation of the injection flow is much larger. Prepare the following materials before the calibration: Syringe: 5 standard syringes of the corresponding full dimensions of 5ml, 10ml, 20ml, 30ml, and 50ml, without liquid. The steps for calibration are as follows: 1. Pull the syringes to the full dimensions and install them on the syringe pump."L"
