Endotracheal Intubation: Hamilton Medical relies on precision pumps from Schwarzer Precision

Reliable patient ventilation is a vital requirement in intensive care medicine. Our eccentric diaphragm pumps ensure that the endotracheal tube fits perfectly in the trachea by precisely regulating the internal pressure of the cuff.


During endotracheal intubation, a thin tube is inserted into the patient's windpipe. To prevent secretions from entering the mouth, an inflatable silicone cuff at the lower end of the tube seals the windpipe all around.

The Swiss company Hamilton Medical has developed the IntelliCuff®. This compact mobile device can be used immediately without prior calibration. The IntelliCuff® covers a wide range of cuff pressures for different endotracheal tubes. The device monitors the cuff pressure and maintains it continuously to protect patients from tracheal injuries and ventilator-associated pneumonia (VAP).

To regulate the internal cuff pressure, Hamilton Medical sought a compact precision pump that could be accommodated in the very small installation space of the handheld device. At the same time, the pump had to ensure quiet and energy-efficient operation. Hamilton Medical chose our SP 270 EC-LC eccentric diaphragm pump. Working closely together, we developed a special version that was perfectly adapted to the desired requirements with reduced speed and stroke.

The current generation of IntelliCuff® is equipped with our SP 240 EC-LC-SO precision pump. It features patented noise reduction technology that enables IntelliCuff® to operate almost silently.
