新生小鼠呼吸机 -尊龙凯时网娱乐官网

型号：minivent

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。

小鼠呼吸机的主要特点：

1 是针对体重小于18g小动物的理想选择，譬如新生小鼠.小鸟；

2 潮气量0-130ul；

3 呼吸频率在60-400次/分钟；

4 在小动物奔跑时可简单的调整心脏搏动容量；

5 结构密室，与实验动物更贴近；

6 减震设计，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.
the microvent ventilator is supplied with the following components:
ac power supply (115 v or 220 v)
silicone tubing, 1.5mm id, 3.0 mm od,14cm length
73-2731 1.0 mm od tracheotomy cannula
73-2737 1.0 mm od intubation cannula
