A simple, sturdy metal box was designed and utilized to protect indwelling central venous and aortic arch catheters in miniature swine. These catheters were easily maintained for 14 days in unrestrained, free-roaming animals while precise amounts of fluids were infused, serial blood samples were taken, and blood pressure recordings and cardiac output measurements were made.
设计并使用了一个简单、坚固的金属盒来保护小型猪体内的中心静脉导管和主动脉弓导管。在不受限制、自由活动的动物身上，这些导管可以轻松维持14天，在此期间可以精确输注液体、采集系列血样，并进行血压记录和心输出量测量。
