Micro Vent 超低容量呼吸机，专门用于新生小鼠和小鸟。 新型的MicroVent 型呼吸机的特点：安静、紧凑、重量轻。虽然它是特别为小鼠设计的，但是也适合其他呼吸体积范围在0-130ul，呼吸速率在60-400次/分钟的一些动物，如小鸟和产期的小鼠。

MicroVent呼吸机是一种基于Starling原则的常量体积呼吸泵。与传统用于更大动物的呼吸机不同，这款呼吸机采用旋转式活塞没有阀门。在每个呼吸循环，这活塞执行一个前进和旋转的同步运动。在气缸和活塞中巧妙地设置了小孔和通道在每个活塞冲程的过程中控制呼吸。

呼吸机的重量极轻（<1.5kg）和紧凑的结构，便于移到另外动物处使用。对于MicroVent而言，潮气量误差小于3ul

潮气量和呼吸速率可被精确的设置。这个精度和控制的程度，可用于了解换气过度和换气不足的危险性。

潮气量可在操作过程中，无须停机 从0-130ul范围连续变化。呼吸速率也可从60-400次/分钟连续调整。呼出的气体可以通过采样口进行收集，用户再循环或者用于产生PEEP。室内气体和其他非爆炸性气体混合物都可用于气体的供给。

The newly developed MicroVent Model 848 Ventilator is a quiet， compact and light weight ultralow volume ventilator. The MicroVent is the ideal ventilator forvery small animals (e.g. birds and perinatal mice) which requires tidal volumes in the range of 0 to 130 μl and respiratory rates of 60 to 400 breaths per minute.The MicroVent Ventilator is a constant-volume respiration pump operating on the Starling principle. Unlike conventional units for larger animals， this ventilator employs a rotary plunger and has no valves. During each ventilation cycle， the plunger performs a synchronized forward and rotating movement. Cleverlyarranged bores and channels in the cylinder and plunger control inspiration and expiration during each stroke of the plunger.The extremely light weight and compact construction， in addition to the convenient rod clamp， allow the MicroVent ventilator to be positioned directly next to the animal. Typical setups with largerventilators produce large tubing and instrument dead space volumes. These larger volumes introduce greater system compliance which can affect the accuracy with which the full tidal volume is introduced into the animal’s lungs. With the MicroVent， the tidal volume error due to system compliance is reduced to less than 3 μl.Tidal volume and respiration rate can be set exactly to the values required for animal ventilation. The level of precision and control available to the investigator minimizes the danger of hyperventilation or hypoventilation.The tidal volume can be varied continuously from 0 to 130 μl during operation without having to interrupt ventilation. The respiration rate is also continuously adjustable from 60 to 400 strokes/min. The expired air can be recovered at the collection port for sampling， recycling or for the generation of a positiveend-expiratory pressure (PEEP). Room air or any non-explosive gas mixture can be used to feed the pump intake.A multi-gas inlet adapter is available for the MicroVent so that alternate gas mixtures and nebulized substances are delivered to the MicroVent inlet port at atmospheric pressure. The adapter provides ports for multiple selectable gas mixtures (hypoxic， anesthetic ... ) and a port for the Aerosol Nebulizer.

The MicroVent Ventilator is supplied with the following components:

AC Power Supply (115 V or 220 V)
