Description

可收集小动物排泄物的睡眠剥夺装置 技术领域
本发明属于动物实验器材技术领域，具体地讲，涉及一种可收集小动物排泄物的睡眠剥夺装置。
背景技术
充足的睡眠是维持机体各项生理功能有序运作的重要条件之一，短期或长期睡眠不足会引起机体生理功能紊乱，其中包括肠道菌群、代谢、废物排泄等功能，通过对机体排泄物(粪便及尿液)成分的分析可探究睡眠不足对机体上述功能的影响。
现有常用的睡眠剥夺仪使用方法主要分为平台水环境法(如中国专利公开号为“CN213343862U”的实用新型)、强迫跑动法(如中国专利公开号为“CN201775854U”的实用新型)、电刺激法及转棒剥夺法(如中国专利公开号为“CN211482388U”的实用新型)。水平台环境法由于其底部环境的限制，无法收集小动物的排泄物；强迫跑动法的原理是使小动物不间断运动达到睡眠剥夺的目的，而过量运动可能会导致小动物的生理指标发生改变，增加了睡眠剥夺之外影响排泄物的因素；电刺激法由于导致较强的应激，也存在引起小动物过生理指标发生改变的可能。转棒剥夺法是目前接收程度较高，睡眠剥夺手段较温和，也不会引入例如运动过量等变量的方法，但由于其睡眠剥夺装置通常位于底座，排泄物无法及时分离和收集，且易造成对电机的污染。目前做法是在睡眠剥夺后后连续6小时以上的代谢笼收集；然而，在进行睡眠剥夺造模后的动物会出现反弹式睡眠，导致排泄物收集量过少或甚至收集不到；同时动物睡眠觉醒状态的改变会影响动物代谢和排泄功能，以致未能获得可靠数据；另外，由于钠盐代谢等生理过程存在节律性，睡眠剥夺与排泄物收集时间错开可能由于本身的节律性得不到真实的结果。

附图说明
图1为本发明的实施例一的可收集小动物排泄物的睡眠剥夺装置的示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
在详细描述本申请的各个实施例之前，首先简单描述本申请的技术构思：现有技术中的小动物睡眠剥夺装置，通常将睡眠剥夺设备安装在底部，这样导致在进行睡眠剥夺时，无法及时分离和收集排泄物。为此，本申请提供了一种可收集小动物排泄物的睡眠剥夺装置，在笼体的上方安装驱动机构，将转动棒伸入于笼体内，利用转动棒扰动笼体内的实验动物，并将排泄物收集组件安装在笼体的下方，收集实验动物收集的排泄物。通过将睡眠剥夺组件和排泄物收集组件上下分离设置，可以避免睡眠剥夺组件对排泄物的分离和收集造成干扰。
具体地，如图1所示，本实施例一公开的可收集小动物排泄物的睡眠剥夺装置包括笼子、睡眠剥夺组件、排泄物收集组件。其中笼子包括笼体11和安装于笼体11下端的网格笼底12，网格笼底11用于承载笼体11内的实验动物并滤 出实验动物的排泄物。睡眠剥夺组件包括驱动机构和转动棒，驱动机构安装于笼体11的上方，转动棒从上至下伸入于笼体内，驱动机构用于驱动转动棒进行转动，以实现对笼体11内的实验动物的扰动。其中，网格笼底12可拆卸地安装于笼体11的下端，便于拆下网格笼底12进行清洗。
进一步地，转动棒包括纵轴转棒21和横轴转棒22，纵轴转棒21竖直设置于笼体11内，横轴转棒22水平连接于纵轴转棒21上，驱动机构用于驱动纵轴转棒21进行竖直转动，以带动横轴转棒22进行水平转动，迫使小动物躲避横轴转棒22，实现对小动物进行睡眠剥夺。示例性地，纵轴转棒21长度为8cm，横轴转棒22长度为12cm。其中，纵轴转棒21和横轴转棒22的长度可根据实际需求进行设置，在此不进行限定。相对于现有技术中，通过旋转台和挡板强迫动物无法入睡的睡眠剥夺方式，本实施例通过强迫动物躲避转棒的睡眠剥夺方式更加温和，且能适用于完全睡眠剥夺需求。
进一步地，横轴转棒22与纵轴转棒21可拆卸连接，且横轴转棒22可沿着纵轴转棒21的高度方向移动，这样可以调整横轴转棒22的转动高度，以适应不同体型的实验动物，达到充分睡眠剥夺的效果。同时，采用可拆卸的方式，可拆下横轴转棒22与纵轴转棒21进行清洗，也可更换不同长度的横轴转棒22与纵轴转棒21。
示例性地，睡眠剥夺组件还包括螺丝件23，纵轴转棒21的侧壁具有竖直分布的螺纹条，螺丝件23与横轴转棒22固定，且螺丝件23与螺纹条螺纹连接。通过拧动螺丝件23可实现横轴转棒22的上下移动。螺丝件23采用M6螺丝件。
进一步地，笼子还包括笼盖13，笼盖13盖设于笼体11的上端；驱动机构包括电机24和联轴器25，电机24安装于笼盖13上，纵轴转棒21的顶端通过联轴器25与电机24的输出轴固定连接，通过调节电机24的转速，对横轴转棒22进行转速调节，适应完全睡眠剥夺或片段式睡眠剥夺的造模需求。
驱动机构还包括减震垫26，减震垫26设置于笼盖13上，电机24安装于减震垫26上，实现对电机24的缓冲，保证电机24转动过程中的稳定性。
进一步地，排泄物收集组件包括锥体型漏斗31、过滤网32和收集瓶33，锥体型漏斗31的大口端可拆卸地连接于笼体11下端的边缘，收集瓶33连接于锥体型漏斗31的小口端，过滤网32设置于锥体型漏斗31中，过滤网32用于分离并收集排泄物中的固体排泄物，收集瓶33用于收集排泄物中的液体排泄物。
示例性地，锥体型漏斗31的大口端通过卡口卡接的方式固定在笼体11下端的边缘。本实施例的睡眠剥夺组件和排泄物收集组件的拆卸组装，因此不固定使用空间和使用场所，便于携带、运输、组装和清洗。
进一步地，笼子还包括饮水器14和喂食器15，笼体11的侧壁上开设有第一开口和第二开口，饮水器14安装于第一开口，喂食器15安装于第二开口。将实验动物的进食进水与代谢收集笼体分开，避免饮用水和食物残渣对排泄物的污染。
本实施例提供的可收集小动物排泄物的睡眠剥夺装置，其灵活度高，应用场景广，睡眠剥夺方式较为温和，排泄物收集方便，能达到睡眠剥夺与排泄物收集的有效统一。
上面对本发明的具体实施方式进行了详细描述，虽然已表示和描述了一些实施例，但本领域技术人员应该理解，在不脱离由权利要求及其等同物限定其范围的本发明的原理和精神的情况下，可以对这些实施例进行修改和完善，这些修改和完善也应在本发明的保护范围内。
