The equipment used for the first sampling of arterial blood at depth on free-diving Weddell seals Leptonychotes weddelli is described. Blood was withdrawn through an aortic catheter by a submersible, peristaltic roller pump and stored in a single- or multiple-sample collection device. The multiple sampler allowed up to eight individual blood samples to be collected during a single dive. The blood pump was controlled by a dedicated microcomputer that allowed initiation of blood sampling at flexible combinations of depth and/or time during either the descending or ascending phase of the dive. The dedicated microcomputer also recorded swimming depth, velocity, heart rate, and body temperature at selectable time intervals. These data were transmitted to a laboratory computer, and blood samples were retrieved, when the seal surfaced to breathe.
本文描述了用于首次对自由潜水的威德尔海豹（Leptonychotes weddelli）进行深度动脉血采样的设备。血液通过主动脉导管由一个潜水蠕动泵抽取，并储存在单样本或多样本采集装置中。多样本采集器允许在单次潜水中采集多达八个独立的血样。血泵由一台专用微型计算机控制，该计算机允许在潜水的下降或上升阶段，以深度和/或时间的灵活组合启动血样采集。专用微型计算机还以可选择的时间间隔记录游泳深度、速度、心率和体温。当海豹浮出水面呼吸时，这些数据被传输到实验室计算机，血样也被取回。
