A breath capture device for determining the concentration of acetone in a breath sample from a user. In some embodiments, the device includes a controller programmed to use stored data to control flow of a breath sample into an analysis chamber as the user exhales into a port. In other embodiments, the device includes a switch responsive to an action by the user that is operable between a first orientation in which breath entering the port preferentially travels through a second flow path and a second orientation in which breath entering the port preferentially travels through a first flow path. In still other embodiments, the device includes a flow regulator both responsive to user action and operable from a first position in which breath entering a port preferentially travels through a second flow path to a second position in which breath entering the port preferentially travels through a first flow path.
一种用于确定用户呼气样本中丙酮浓度的呼气采集装置。在某些实施例中,该设备包括一个控制器,该控制器通过编程使用存储的数据,在用户向端口呼气时控制呼气样本流入分析室。在其他实施例中,设备包括一个响应用户动作的开关,该开关可在第一方向和第二方向之间操作,在第一方向上,进入端口的呼吸优先通过第二流动路径,而在第二方向上,进入端口的呼吸优先通过第一流动路径。在其他一些实施例中,设备包括一个流量调节器,该调节器既可响应用户的操作,又可从气息优先通过第二流动路径进入端口的第一位置操作到气息优先通过第一流动路径进入端口的第二位置。
