Product Description
Welch Allyn Spot Vital Signs Lxi pump assembly models include M26B18153R, 0140522, P05C09R, and 14526. Each model has a different focus: the M26B18153R is a basic drive pump, the 0140522 integrates an integrated pressure feedback module, the P05C09R features an enhanced low-noise design, and the 14526 emphasizes long-life operation. These pumps are suitable for high-frequency use in outpatient and emergency settings.
The pump assembly has a rated voltage of DC 6V and integrates a drive motor, pressure regulating valve, and noise-reducing housing. Its primary function is to provide precise pneumatic power for inflation and deflation of the blood pressure cuff. The assembly features a very compact design, measuring approximately 65mm * 45mm * 30mm and weighing approximately 85g.
Key Features
-
Precise Pressure Control
During NIBP measurement, the device receives and executes commands from the host computer, rapidly inflating the cuff to the preset pressure with a high inflation rate. During the deflation phase, a built-in proportional valve achieves linear deflation, ensuring the pressure sensor captures subtle changes in arterial pulses and providing a stable pressure gradient for systolic and diastolic pressure calculations.
-
Pressure Feedback and Regulation
Model 0140522 features a built-in piezoresistive pressure sensor that monitors the pump's output pressure in real time to adjust the pump speed and avoid overpressure that could cause patient discomfort.
-
Low-Noise Operation
The P05C09R pump is encased in a sound-absorbing foam, resulting in an operating noise level of ≤45dB, significantly lower than that of standard pump components. This reduces environmental noise in clinics, wards, and other settings, enhancing patient comfort.
-
Overload and Overheat Protection
The pump incorporates an integrated overcurrent protection circuit that automatically shuts off power if the motor is overloaded due to airway obstruction. A built-in temperature sensor triggers thermal protection when the pump temperature exceeds 60°C, preventing motor burnout and extending component life.
Frequently Asked Questions
Q1: The pump assembly suddenly becomes noisier during operation. What could be the cause?
A1: There are many reasons for increased noise during operation. Common causes and solutions include:
- The diaphragm is aging and cracking, requiring replacement of the pump assembly.
- The eccentric is worn, causing excessive clearance. Check the motor shaft for looseness.
- The air path is clogged, causing the pump to overload. Clean the cuff connector or air path. If this doesn't work, replace it.
Q2: How do I determine if the pump assembly needs replacement?
A2: Replacement is recommended if any of the following conditions occur:
- Abnormal vibration or odor occurs during operation (a precursor to motor failure).
- Inflation time exceeds 30 seconds (normal ≤ 15 seconds).
- Pressure fails to reach the preset value (e.g., <200 mmHg in adult mode).
- Deflation rate fluctuations exceed 1 mmHg/s.
Q3: What is the warranty period for this assembly?
A3: All products in our store have a 90-day warranty. If any quality issues arise during the warranty period, please contact our staff for a consultation. If the damage is caused by other factors, such as damage, liquid immersion, or abnormal voltage, it is not covered by the warranty. It is recommended to check the pump body sealing regularly (every 6 months).
