型號MiniVent
MicroVent 是一種基于Starling原則的常量體積呼吸泵。與傳統(tǒng)用于更大動物的不同這款采用旋轉(zhuǎn)式活塞沒有閥門。在每個呼吸循環(huán)這活塞執(zhí)行一個前進和旋轉(zhuǎn)的同步運動。在氣缸和活塞中巧妙地設(shè)置了小孔和通道在每個活塞沖程的過程中控制呼吸。
的重量極輕（<1.5kg）和緊湊的結(jié)構(gòu)便于移到另外動物處使用。對于MicroVent而言潮氣量誤差小于3ul
潮氣量和呼吸速率可被精確的設(shè)置。這個精度和控制的程度可用于了解換氣過度和換氣不足的危險性。
潮氣量可在操作過程中無須停機 從0-130ul范圍連續(xù)變化。呼吸速率也可從60-400次/分鐘連續(xù)調(diào)整。呼出的氣體可以通過采樣口進行收集用戶再循環(huán)或者用于產(chǎn)生PEEP。室內(nèi)氣體和其他非爆炸性氣體混合物都可用于氣體的供給。
小鼠的主要特點
1 是針對體重小于18g小動物的理想選擇譬如新生小鼠.小鳥；
2 潮氣量0-130ul；
3 呼吸頻率在60-400次/分鐘；
4 在小動物奔跑時可簡單的調(diào)整心臟搏動容量；

6 減震設(shè)計低噪音
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.
