定量吸入气雾剂(MDI)与呼吸驱动吸入气雾剂(BAI)的DDU递送剂量均一性测试

DDU是从吸入器中排出并因此可供患者使用 的药物总量。均一性试验可确保患者在设备使 用寿命期内均能从单剂量或多剂量吸入 器正确摄取声明剂量的药物。 适配MDI的单位剂量取样仪(DUSA) 以美国明尼阿波利斯3M实验室的Charles Thiel的原创设计为基础, 专用于MDI和鼻用气雾剂的取样和试验。 这款取样仪的便携手提箱内配有一根收集管, 两个冲洗盖, 一个过滤器支撑盖和一个流量计盖。

Breath Actuation Controller BAC 100i

Breath-Actuated MDIs (BAIs)

The Breath Actuation Controller BAC 100i can also be used for the testing of Breath-Actuated (or Breath-Operated) MDIs. In this case, the BAC 100i is used to initiate the flow, simultaneously triggering the breath-actuated inhaler.

Vertus - DDU - MDIs

MDIs: Semi-Automated DDU Testing

The Vertus automated shake, fire and shot waste range is made up of integrated turn-key solutions for precise, controlled and reproducible MDI testing. Compatible with most MDIs, the Vertus systems offer analysts complete control over:

  • The speed, angle and duration of shaking, ahead of actuation
  • Firing force and the speed of application and release of that force
  • The time delay between the end of shaking and device actuation
