Datamax/BPL多通道生理数据获取仪
Datamax/BPL是一计算机化的低成本设备，用于获取生理学波形函数（多至8通道）。它尤其适用于监测血压和心率，并可通过电脑记录数据。并可以使用用户自己的传感器监测8通道的模拟信息。这个设备包括一个8通道通用传感器接口，一个A/D卡（12bits）和全面的软件。传感器接口可以直接连接所有兼容的“桥”型血压传感器。传感器接口同样可以连接用户自己的B.P.放大器，进行模拟电压输出。所有通道都可以对周期性波形进行实时分析。仪器还可以持续地计算zei大和zei小的波形频率脉冲、显示以及定期打印或存储。任一信号波形快照可被保存，以用于以后的检索分析。
软件通过用户导向指针，允许用户对数据进行获取后分析；波形上任意一点上的测量时间、振幅和dp/dt。用户可以调节每个通道上的取样速率，从10次/秒到1000次/秒。仪器运行时可以显示所有通道上心脏收缩压、心脏舒张压、平均压和心率。程序的增强版本允许用户保存波形快照。快照中波形的数量取决于取样速率，如果取样速率为500次/秒，则快照中会包含zei后4秒的波形；如果取样速率为50次/秒，则快照中会包含那个通道zei后40秒的波形信息。

Datamax/BPL
Datamax/BPL is a computerized and low cost device for acquisition of physiological wave form functions (up to 8 channels). It is especially useful for monitoring blood pressure and heart rate and recording them on an PC/AT compatible computer. The 8 channels of analog information can be monitored using the customer's own transducers. The device includes an 8 channel universal transducer interface, an A/D card (12 bits) and comprehensive software. The Transducer Interface can be connected directly to all compatible blood pressure "bridge" type transducers. It may also be connected to analog voltage outputs from the customer's own B.P. amplifiers. Real time analysis of periodic wave forms is performed on all channels. The frequency plus the maximum and minimum of the wave forms is continually calculated, displayed and periodically printed or saved to disk. The snapshots of any wave forms can be saved to disk and later retrieved for analysis.
Software allows post-acquisition analysis through the use of a user-directed cursor; permitting measurement of time, amplitude and dp/dt for any point on the wave form. The sampling rate for each channel is adjustable within the range of 10 to 1,000 samples per second. The run time screen shows systolic, diastolic and mean blood pressure as well as the heart rate for all channels. The enhanced version of the program allows the user to store snapshots of the wave form to disk. The number of wave forms in the snapshot depends on the sampling rate. If the sampling rate is 500 samples per second, the snapshot will contain the last 4 seconds of the wave form. If the sampling rate is 50 samples per second, the snapshot will contain the last 40 seconds of information for that channel.
