Mindray N1 Monitor NIBP Tracheal Components pneumatic circuit Assembly Used NIBP parts Medical Parts
■ Product Describe
The NIBP air circuit assembly for the Mindray N1 monitor is a disassembled accessory. This accessory is used but still functional. It is a crucial component for the monitor's non-invasive blood pressure measurement.
It primarily connects the NIBP pump, cuff, and pressure sensor, forming a complete gas flow and signal transmission channel.
This assembly features a modular design that fits the compact structure of the N1 monitor. Standardized dimensions ensure a tight and stable gas transmission, making it a key auxiliary component for ensuring accurate non-invasive blood pressure measurement.
■ Product features
1. Gas Transmission and Sealing
The air circuit assembly accurately transmits gas through a sealed tube, ensuring sufficient pressure during blood pressure measurement. This ensures that the pressure sensor accurately captures pressure fluctuations within the cuff, providing reliable raw data for systolic and diastolic pressure calculations.
2. Pressure Signal Transmission
The pressure fluctuations in arterial pulse pressure sensed by the cuff during deflation are transmitted to the pressure sensor within the monitor via a gas medium, preventing signal attenuation or distortion. 3. One-way Flow Control
The integrated one-way valve prevents sudden pressure drops caused by gas backflow, ensuring a steady increase in cuff pressure during inflation. This ensures rapid occlusion of arterial blood flow, especially when measuring hypertension, and reduces measurement preparation time.
4. Connectivity
A standardized interface allows for quick docking with NIBP pumps and cuffs. The interface insertion and removal force is controlled between 15-30N, ensuring a secure connection (tensile strength ≥ 50N) and facilitating interchange of cuffs of different sizes (adult, pediatric, and neonatal). Compatible with all Mindray NIBP cuff accessories.

■ FAQ
Q1: What are the symptoms of a leak in the airway assembly?
A1: Slow cuff inflation, sudden pressure drop during measurement, the monitor displaying "Insufficient Pressure," or measurement failure. If any of these conditions occur, the airway may be leaking.
Q2: How do I determine if the airway assembly needs to be replaced?
A2: Replacement is recommended when:
① The airway surface is hardened, cracked, or the inner wall is sticking;
② The connector is worn, causing loose insertion and removal;
③ The surface is damaged after repeated disinfection, making biocompatibility unreliable.
Q3: How do I clean the airway assembly during routine maintenance?
A3: After each use, wipe the airway surface and connector with a soft cloth dampened with 75% alcohol to prevent alcohol from seeping into the interior. Regularly (weekly) check the airway for kinks and blockages. Perform an air blow test to verify patency. Store away from direct sunlight and oily substances.
