Philips X3 Patient Monitor Pump and Solenoid Valve Assembly 453564521721

Philips X3  Pump and Solenoid

Pump and Solenoid  Valve Assembly 453564521721 For Philips X3 Patient Monitor

► Brief Description

This product is a miniature pump and solenoid valve assembly (part number: 453564521721) specifically designed for NBP monitoring modules. This assembly includes a miniature brushless DC pump and a high-speed response precision solenoid valve, tightly connected via internal tubing and a circuit board to form a complete pressure control unit. Its core function is to provide precise, rapid, and stable inflation and deflation control for the blood pressure cuff. During measurement, the pump quickly builds up the required pressure, while the solenoid valve precisely deflates or rapidly deflates according to a preset program. This collaborative operation ensures high-precision acquisition of systolic, diastolic, and mean arterial pressure data. It is a key component for realizing the NBP monitoring function of the X3 Monitor.

► Specification

►Preparing to Measure NBP

1. Connect the cuff to the air tubing.

2. Plug the air tubing into the red NBP connector. Avoid compression or restriction of pressure tubes. 

Airmust pass unrestricted through the tubing.

►Product Functions

1. Precise Inflation Control: The miniature air pump is responsible for the precise inflation of the cuff during blood pressure 

measurement. It adjusts the inflation pressure and rate according to device instructions to ensure the cuff pressure matches 

clinical measurement needs.

2. Intelligent On/Off and Pressure Control: The solenoid valve uses electromagnetic induction to quickly open and close the 

air path, precisely controlling the cuff's pressure maintenance and staged deflation process. Combined with the device's algorithm,

it accurately identifies systolic and diastolic blood pressure values, avoiding measurement errors caused by excessively fast or slow 

deflation.

3. Safety Protection: A built-in overpressure relief mechanism automatically opens the pressure relief channel when the cuff

pressure exceeds the safety threshold, preventing discomfort to the patient due to excessive pressure. This fully complies with 

medical electrical equipment safety standards.

4. Status Feedback Adaptation: The system provides real-time feedback of pump operating status and solenoid valve 

opening/closing signals to the monitor's mainboard, supporting automatic identification and alarm for air path faults, 

facilitating timely troubleshooting by medical staff.
