提供了用于输送受控浓度的试剂的装置。该装置包括用于试剂的贮存器和可操作地连接到该贮存器的流量控制部分。该装置还包括用于从流量控制部分释放试剂的阀，以及用于使空气流动以与由阀释放的试剂混合并且用于使试剂和空气混合物流出装置的泵。还提供了将汽化试剂输送至受试者的方法。该方法包括将液体试剂存储在装置的贮存器中，并使试剂流入流量控制室以将试剂转化为气体。该方法还包括将气体形式的试剂与空气混合，并使试剂和空气混合物流出装置以输送至受试者。 Devices for delivering a controlled concentration of an agent are provided. The device includes a reservoir for the agent and a flow control portion operably connected to the reservoir. The device also includes a valve for releasing the agent from the flow control portion and a pump for flowing air to mix with the agent released by the valve and for flowing the agent and air mixture out of the device. Methods of delivering a vaporized agent to a subject are also provided. The methods include storing a liquid agent in a reservoir of a device and flowing the agent into a flow control chamber to change the agent to a gas. The methods also include mixing the agent in gas form with air and flowing the agent and air mixture out of the device to be delivered to a subject.
