A T-cannula was designed for placement in the gastrointestinal tract of pigs used for nutritional studies. It was made from available and inexpensive polyvinylchloride plumbing fittings. The main advantages of the cannula are (1) light weight (32 g), (2) good tolerance by the animals, (3) short projection from the body wall, (4) minimal leakae, and (5) patency for several months. The caudal part of the ilea of ten pigs was cannulated with satisfactory results. Macroscopic alterations of the gastrointestinal tract were not observed when the animals were euthanatized.
一种T型套管被设计用于放置在用于营养研究的猪的胃肠道中。它由现有的且价格低廉的聚氯乙烯管道配件制成。该套管的主要优点包括：（1）重量轻（32克），（2）动物耐受性良好，（3）从体壁突出部分短，（4）渗漏极少，（5）几个月内保持通畅。对十头猪的回肠尾部进行了套管插入，结果令人满意。对动物实施安乐死后，未观察到胃肠道有宏观变化。
