■ Product Describe
Mindray UMEC12 Patient Monitor Mini Pump Assembly is a monitor accessory, a used accessory, but in good condition and meets medical safety standards. It is a miniature air pump system, mainly used for non-invasive blood pressure measurement, responsible for inflating and exhausting the blood pressure cuff, can accurately control the air pressure changes, and cooperate with the pressure sensor to calculate blood pressure (including systolic pressure, diastolic pressure) and pulse rate. It can be used in a variety of medical use scenarios, such as non-invasive blood pressure monitoring, with conventional blood pressure monitoring and continuous automatic detection mode (intraoperative monitoring); emergency rescue, rapid blood pressure detection in ambulances, emergency rescue outside hospitals, and field first aid and other mobile scenarios; the blood pressure cuff is replaceable, and the cuff length can be adjusted according to different body shapes, which can be adapted to different patient groups, including children.
Daily use requires regular maintenance and regular cleaning of the air path interface to avoid dust accumulation and air path blockage. Air pump leakage will cause the pump to work frequently, resulting in a shortened life of the accessories, so users need to regularly check whether there is air leakage at the cuff connection to avoid such consequences in time.
■ Product Picture
■ Working principle
1. When inflating, after the main control board receives the command, the drive motor drives the pump to inflate the cuff to the preset pressure (the pressure values for adults and children are different, and the adult mode is usually 180-220mmHg)
2. The sensor provides real-time feedback to the pump and adjusts the pressure of the cuff at any time
3. After the measurement is completed, open the solenoid valve, and the pump quickly exhausts air by running in reverse

■ Product advantages
1. Precise control
The micro pump assembly uses a closed-loop control algorithm to ensure the repeatability and accuracy of blood pressure measurement
2. Low power consumption
The motor is more efficient, which increases the battery life of the monitor, which is very critical in the process of emergency operation of patients. Time is life
3. Compact structure
The design is compact, and the size of the entire assembly is about 5×3×2cm, which is very suitable for the portability of Mindray UMEC12 Patient Monitor.
4. Durable
The brushless motor and wear-resistant seals reduce wear and tear during long-term use.
