实现加压气体容器的最佳与安全使用的注气装置
摘要：
一种医疗气体注气装置(1)，所述医疗气体注气装置至少包括气体输出回路(7)；用于连接加压容器(3)的连接器(2)，其中在所述加压容器内包含有气体；位于所述连接器(2)与所述气体输出回路(7)之间的膨胀器(4)；位于所述连接器(2)与所述膨胀器(4)之间的高压传感器(5)；位于所述膨胀器(4)的出口处的流量计(6)；以及微处理器(8)，其中所述微处理器至少连接至所述传感器(5)以接收代表在所述连接器(2)处所出现的压力的信号、并连接至所述流量计(6)以接收代表所述膨胀器(4)的出口处的流速的信号，所述医疗气体注气装置其特征在于，所述微处理器(8)包括评价装置，用于作为在气体膨胀操作的过程中从所述传感器(5)和所述流量计(6)接收的信号的函数评价膨胀之后气体的剩余容积。
摘要（英）：

The invention relates to a medical gas blowing device (1) that comprises at least a gas outlet circuit (7), a connector (2) for connecting a pressurised vessel (3) in which the gas is conditioned, a regulator (4) provided between the connector (2) and the gas outlet circuit (7), a high pressure sensor (5) provided between the connector (2) and the regulator (4), a flow-meter (6) provided at the outlet of the regulator (4), a microprocessor (8) connected at least to the sensor (5) for receiving signals representative of the pressure observed at the connector (2), and to the flow-meter (6) for receiving signals representative of the outlet flow rate of the regulator (4), characterised in that the microprocessor (8) comprises means for estimating a remaining gas volume after expansion according to the signals received from the sensor (5) and the flow-meter (6) during a gas expansion.
