    • A medical insufflation device having a control device with feedback sensors for regulating the flow of a gas into an inflatable body cavity. The device includes a conduit for channeling gas from a gas supply into an insufflation instrument, sensors for measuring gas pressure and gas flow in the conduit, and a control device responsive to the sensors for automatically regulating the pressure and flow of the gas into the body cavity from the conduit. The control device has an automatic processing unit for receiving the measured gas pressure and flow values from the sensors and for using those values to control an actuator in the conduit and which is operatively adjustable for regulating the flow of gas into the body cavity. During insufflation, when the pressure sensor detects a drop in pressure or that the measured pressure is no longer increasing, the control device automatically operates the actuator to reduce the pressure in the conduit until the gas flow falls to a minimum value such, for example, as zero while the body cavity remains open.
    • 一种具有控制装置的药物吹入装置,所述控制装置具有用于调节气体进入可充气体腔的流量的反馈传感器。 该装置包括用于将气体从气体供给引入吹气器的导管,用于测量导管中的气体压力和气体流量的传感器,以及响应于传感器的控制装置,用于自动调节气体进入体内的压力和流量 空腔从导管。 控制装置具有自动处理单元,用于从传感器接收测量的气体压力和流量值,并且使用这些值来控制导管中的致动器,并且其可操作地可调节以调节进入体腔的气体流。 在吹气期间,当压力传感器检测到压力下降或测量的压力不再增加时,控制装置自动操作致动器以减小管道中的压力,直到气流下降到最小值,例如, 作为零,同时体腔保持开放。
