Description

一种小鼠持续肠内营养输注装置
技术领域
本发明涉及一种医学实验用具，具体是一种小鼠持续肠内营养输注装置。
背景技术
小白鼠是野生鼠的变种，是普遍用在生理学、医学、药学等学科的教学与研究中作为实验动物的白色老鼠，由于小白鼠的基因序列和人类的差不多，小白鼠广泛应用于食品、化妆品、药品、生物制品、工业产品和医学及生命科学等的安全性、毒性和效力等方面的实验和检验。小白鼠在进行实验和检验时，为了保证小白鼠的正常生长和正常活动的进行，需要对小白鼠进行肠内营养支持，这就需要肠内营养灌输装置。但是目前市场上现有的肠内营养灌输装置会影响小白鼠的自由活动和自由饮食，对小白鼠的生物学行为影响大，对实验结果的准确性有影响，而且制作工艺复杂，设备成本高。
发明内容
本发明的目的在于提供一种小鼠持续肠内营养输注装置，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种小鼠持续肠内营养输注装置，包括弹簧、塞子、漏斗、针头、输入管、扣环和输出管，所述弹簧的一端安装有漏斗，弹簧的内径大于漏斗下部的外径，漏斗内设置有输出管，输出管的外径小于漏斗下端的内径且输出管贯穿整个弹簧，弹簧另一端安装有塞子，针头与输入管相连，针头尖锐的一端插入塞子中，针头和弹簧通过扣环相连。
作为本发明进一步的方案：扣环和弹簧均采用不锈钢材质制作，漏斗、输入管和输出管均采用聚乙烯材质制作。
作为本发明进一步的方案：塞子的形状为圆筒形。
与现有技术相比，本发明的有益效果是：该装置结构简单，设计合理，操作简单方便；不会影响小白鼠的自由活动和自由饮食，对小白鼠的生物学行为影响小，降低对小白鼠的干扰，成功率高，提高实验的准确性；该装置可以长期持续使用，制作工艺简单，生产成本低，实用性好，适用范围广。
附图说明
图1为小鼠持续肠内营养输注装置的结构示意图。
其中：1-弹簧，2-塞子，3-漏斗，4-针头，5-输入管，6-扣环，7-输出管。
具体实施方式
下面结合具体实施方式对本专利的技术方案作进一步详细地说明。
请参阅图1，一种小鼠持续肠内营养输注装置，包括弹簧1、塞子2、漏斗3、针头4、输入管5、扣环6和输出管7，所述弹簧1的一端安装有漏斗3，弹簧1的内径大于漏斗3下部的外径，漏斗3内设置有输出管7，输出管7的外径小于漏斗3下端的内径且输出管7贯穿整个弹簧1，弹簧1另一端安装有塞子2，针头4与输入管5相连，针头4尖锐的一端插入塞子2中，针头4和弹簧1通过扣环6相连。扣环6和弹簧1均采用不锈钢材质制作，漏斗3、输入管5和输出管7均采用聚乙烯材质制作。塞子2的形状为圆筒形。
本发明的工作原理是：在小白鼠身上开个小伤口，将输出管7插入小白鼠的肠内，再将输入管5与含有营养液的针筒和微量泵连接即可。该装置结构简单，设计合理，操作简单方便；不会影响小白鼠的自由活动和自由饮食，对小白鼠的生物学行为影响小，降低对小白鼠的干扰，成功率高，提高实验的准确性；该装置可以长期持续使用，制作工艺简单，生产成本低，实用性好，适用范围广。
上面对本专利的较佳实施方式作了详细说明，但是本专利并不限于上述实施方式，在本领域的普通技术人员所具备的知识范围内，还可以在不脱离本专利宗旨的前提下做出各种变化。
