MiniVent Mouse Ventilator Type 845

The MiniVent Ventilator for Mice (Model 845): A Precision Ventilator for Mice

The MiniVent Ventilator for Mice (Model 845) from Hugo Sachs is a high-precision ventilation device specially designed to meet the specific needs of mice and other small animals such as birds and perinatal rats. This ventilator is compact, lightweight and quiet, making it ideal for use in laboratories where precision and reliability are essential.

The MiniVent operates on the Starling principle, using a valveless piston pump that eliminates the risk of obstruction. This unique mechanism allows precise control of tidal volume and respiratory rate, minimising the risk of hyperventilation or hypoventilation. The tidal volume can be continuously adjusted from 30 to 350 µl, while the respiratory rate can vary from 60 to 400 breaths per minute. These adjustments can be made without interrupting ventilation, ensuring rapid and accurate adaptation to the animal's needs.

One of the main advantages of the MiniVent is its compact design, which allows it to be positioned directly next to the animal. This proximity significantly reduces the dead volume of the circuit and the instrument, improving the accuracy of the tidal volume delivered to the animal's lungs. The dead volume of the system is reduced to ±3 µl, which is much lower than that of larger ventilators.

The MiniVent is also designed to be easy to install and use.

Exhaled air can be recovered at the collection port for sampling, recycling or use to generate positive expiratory pressure (PEEP). The MiniVent can operate with ambient air or any non-explosive gas mixture, offering great flexibility in research applications.

The MiniVent Ventilator for Mice (Model 845) is an essential tool for researchers requiring precise and reliable ventilation for small animals. Its innovative design, ease of use and versatility make it an ideal choice for life science research laboratories.
