一、前言在实验性创伤代谢及实验性静脉营养的研究中,让动物无拘束地接受持续输液是一项不可缺少的技术,而大白鼠则是常用的实验动物之一。国外早在六十年代就有人研究小动物(如大白鼠)在无拘束状态下进行持续输液的技术及其装置,几经改进,直到1981年,日本的大桥弘幸等人又研制出一种据称更具实用价值的大白鼠持续微量输液装置。国内目前尚 I. INTRODUCTION In the research of experimental traumatic metabolism and experimental parenteral nutrition, it is an indispensable technology for animals to freely receive continuous infusion, while the white rat is one of the commonly used experimental animals. As early as in the 1960s, some people studied the technology of continuous infusion of small animals (such as rats) and their devices in a state of unconstrained improvement. Until 1981, Japan’s Hongdae Bridge and others developed an alleged More practical mouse sustained trace infusion device. Domestic is still
