产品描述
塔望科技开发的头外置式体积描记系统(Head-Out Plethysmography),采用特殊设计,使小动物的颈部与身体隔开,口鼻暴露在外面,实时测定容纳身体的腔室内气体容积与压力的变化。Glaab等对哮喘小鼠使用mACh激发后,取呼气中段流量(EF50 )下降55%时的mACh量( EF50)为指标来表示支气管反应的敏感性,研究证明,EF50和RL及CL有较好的相关性,可较好地反映呼吸系统的机械动力学改变。
产品特点
- 采用头外置式体积描记系统测量过程中,动物保持清醒状态,不需要麻醉,避免了创伤性气管切开术及麻醉的影响,使实验过程简便快捷,并适合长期跟踪研究。
- 另外系统可扩展连接雾化给药器,对动物进行雾化给药,建立咳嗽、哮喘等呼吸道疾病模型,系统可检测和记录激发过程中呼吸常规指标和气道高反应的变化,用以评价支气管收缩情况。
- 不需要做手术,操作简单。
- 动物处于清醒状态,结果不受麻醉和手术影响。
- 可以实现在同一只动物上做长期跟踪实验。
- 配备气溶胶雾化模块 。(可根据实验要求选配)
- 可联合同步测量其它信号,如体温、血压、心电信号等。
可连接口鼻暴露系统,实时在线监测动物肺功能指标的变化
