下面结合附图和实施例对本申请进行详细的说明。
请参阅图1和图2,其中,图1为本申请一实施例提供的用于观测动物活动的观测装置的整体结构示意图;图2为图1所对应的装置未装配前的结构示意图;在本实施例中,提供一种用于观测动物活动的观测装置,该装置具体可用于对动物的活动情况进行观测,比如,用于观测动物的头部活动或脊椎部活动;且该装置相比于现有技术中将观测设备直接安装在动物身上的方案,该装置中的观测组件11设置于支撑组件12和/或设置于转动连接在支撑组件12上的固定组件,从而能够大大减少动物的承载重量,进而有效降低因动物承载过重而对动物活动造成的影响。
具体的,该用于观测动物活动的观测装置具体包括观测组件11、支撑组件12以及固定组件(图未示)。
其中,观测组件11设置在支撑组件12和/或固定组件上,用于对动物的活动进行观测。具体的,观测组件11可包括有线电极记录器、在体膜片钳等。
具体的,上述将观测组件11设置在支撑组件12和/或固定组件上,能够通过支撑组件12和/或固定组件承载现有技术中通过动物承载的观测设备,以减少动物的承载重量,进而有效降低因动物承载过重而对动物的活动造成的影响。
在一具体实施例中,观测组件11具体设置在固定组件上,以使固定组件与动物保持相对静止,进而在对动物活动进行观测和/或操作的过程中,能够提高观测结果的准确度和/或操作的便利程度。
在另一具体实施例中,由于支撑组件12的承载面的面积相比于固定组件的承载面的面积较大,观测组件11具体可设置在支撑组件12上,以在保证动物自由活动的前提下,承载更大体积和重量的观测组件11,并增加使用更多观测组件11的可能性,以获取更多的实验数据。
当然,在其它实施例中,也可根据实际情况将部分观测组件11设置在支撑组件12上,部分观测组件11设置在固定组件上;可以理解的是,由于现有技术中的观测设备是直接通过动物承载,为了减少观测设备对动物活动的影响,一些比较复杂精细或者重量较重的设备无法运用在动物活动研究中;且为进一步降低动物的承载负荷以便动物活动,会尽可能地减少设置在动物上的观测设备,但轻量化设计必然会限制功能;而本申请通过设置一可自由活动的支撑组件12,以及转动连接在支撑组件12上的固定组件,以通过支撑组件12和/或固定组件承载观测组件11,不仅不会影响动物的活动,且能够有效解决现有问题;可以理解的是,本申请中的观测组件11相当于现有技术中的观测设备。
其中,支撑组件12可在一平面上自由活动;在一具体实施例中,参见图2,支撑组件12具体包括支撑平台121、多个支撑体122以及多个万向轮123。
其中,支撑平台121具体可为一面板结构;观测组件11具体可通过螺纹连接的方式设置于支撑平台121上;多个支撑体122间隔设置在支撑平台121的一侧表面,用于对支撑平台121进行支撑;具体的,支撑体122可为四个,且支撑体122具体可为支撑柱;多个万向轮123与多个支撑体122一一对应,且万向轮123具体设置在支撑体122远离支撑平台121的一端,以使该支撑组件12能够在一平面上自由活动;可以理解的是,在具体使用过程中,即,将该装置与动物固定之后,支撑组件12在动物的带动下自由活动。
其中,固定组件连接在支撑组件12上,用于与动物固定;具体的,固定组件连接在支撑平台121上;需要说明的是,固定组件具体可与动物的头部、脊椎部、身体部等位置固定,本实施例对此并不加以限制。
在一实施例中,固定组件具体包括第一固定组件13,第一固定组件转动连接在支撑平台121上,用于与动物的头部或脊椎部固定,以通过观测组件11对动物的头部活动或脊椎部活动进行观测;当然,在其它实施例中,第一固定件13也可与动物的四肢等位置固定。可以理解的是,上述第一固定组件13虽与动物的头部或脊椎部固定,但因其转动连接在支撑组件12上,当观测组件11设置在第一固定组件13上时,其受力点仍然是地面,观测组件11不会对动物产生压力,进而不会影响动物的活动。需要说明的是,将该装置与动物固定之后,动物的四肢仍然着地,动物可在当前场地上自由活动,并带动支撑组件12随之转动。
具体的,支撑平台121沿垂直于支撑平台121的方向上设置有圆柱孔1211,第一固定组件13转动连接在该圆柱孔1211中以与支撑平台121转动连接;可以理解的是,第一固定组件13通过圆柱孔1211与支撑平台121转动连接仅为一示范性实施例,本实施例对此并不加以限制。
具体的,参见图2和图3,图3为图1所对应的装置在第二视觉下未装配前的结构示意图;第一固定组件13具体包括伸缩机构131、调节机构132以及固定件133。

在另一具体实施例中,伸缩机构131可仅包括第一伸缩杆1311,第一伸缩杆1311与圆柱孔1211螺接,以通过二者的旋合实现第一伸缩杆1311在圆柱孔1211中的可伸缩;具体的,可在第一伸缩杆1311的外侧壁上设置外螺纹,圆柱孔1211的内侧壁上设置与外螺纹匹配的内螺纹,第一伸缩杆1311具体通过设置在其外侧壁上的外螺纹与圆柱孔1211的内螺纹之间的旋合以实现在圆柱孔1211内的伸缩,进而对整个第一固定组件13在支撑平台121上的高度进行调节。
具体的,上述第一伸缩杆1311可为一中空结构,且第一伸缩杆1311朝向调节机构132的一端内嵌有一轴承134。

其中,第一球体1321转动连接在第一伸缩杆1311的一端;且在一具体实施例中,第一球体1321朝向第一伸缩杆1311的一端还连接有一第一圆盘,第一球体1321具体通过该第一圆盘转动连接在轴承134内圈以实现与第一伸缩杆1311的转动连接。上述在第一圆盘与第一伸缩杆1311之间内嵌轴承134,可以方便动物进行摆头动作或方便动物的脊椎神经活动,减少动物的紧张不适。
其中,第二球体1322固定设置在球体平台1323的第一表面,两个夹持臂1324具体夹持在第一球体1321和第二球体1322的相对两侧,且两个夹持臂1324可沿第一球体1321和第二球体1322的周向方向转动,用于连接第一球体1321和第二球体1322,并对固定件133的位置进行调节。具体的,夹持臂1324可为一椭圆形板状结构。
具体的,该调节机构132还包括夹持臂锁紧阀1326;在具体实施例中,两个夹持臂1324的其中一夹持臂1324的中间位置开设有一连接孔,另一夹持臂1324的中间位置开设有一螺纹孔,夹持臂锁紧阀1326具体穿过夹持臂1324上的连接孔并与另一夹持臂1324上的螺纹孔螺接,以通过夹持臂锁紧阀1326与另一夹持臂1324上的螺纹孔的螺接程度调节两个夹持臂1324对第一球体1321和第二球体1322的夹持力度。可以理解的是,夹持臂锁紧阀1326与夹持臂1324上的螺纹孔拧紧后能够产生更强的夹持力,从而使得两个夹持臂1324能够更紧地夹持第一球体1321和第二球体1322。
具体的,两个夹持臂1324的两端还分别开设有第一凹槽和第二凹槽,两个夹持臂1324具体通过各自的第一凹槽与第一球体1321的表面接触,通过第二凹槽与第二球体1322的表面接触;且第一凹槽的槽壁与第一球体1321的球面形状匹配,第二凹槽的槽壁与第二球体1322的球面形状匹配,以便调节两个夹持臂1324与第一球体1321和第二球体1322之间的相对位置,同时能够更好的实现夹持。

可以理解的是,上述第二固定组件14在具体使用过程中,滑动杆1421穿过条形孔1213以伸入滑槽1212内部,并与螺帽螺接,且在调节好滑动杆1421在滑槽1212中的位置之后,将滑动杆1421和螺帽拧紧以固定二者在滑槽1212中的位置。
其中,第二伸缩杆1423螺接在滑动杆1421上,且可沿滑动杆1421的轴向方向上下伸缩;具体的,绑带141固定连接在第二伸缩杆1423上,第二伸缩杆1423具体用于调节绑带141在垂直于支撑平台121方向上的高度,以收紧或放松绑带141。
具体的,滑动杆1421沿其轴向方向上设置有一第三通孔,第三通孔的孔壁上设置有内螺纹,第二伸缩杆1423的外侧壁上设置有与第三通孔的内螺纹匹配的外螺纹,以通过内螺纹和外螺纹之间的旋合实现第二伸缩杆1423与滑动杆1421之间的螺接,进而通过二者的旋合实现第二伸缩杆1423在滑动杆1421上的可伸缩;具体的,在该实施例中,第二伸缩杆1423的轴向方向上开设有第四通孔,绑带141的一端穿过该第四通孔,并系绑在第二圆盘上,以通过第二圆盘实现与第二伸缩杆1423的连接,进而通过第二伸缩杆1423的伸缩对绑带141在垂直于支撑平台121方向上的高度进行调节;具体的,第二圆盘的横向尺寸大于第四通孔的孔径,以使第二圆盘卡在第四通孔远离固定块1422的一端开口处,进而实现绑带141与第二伸缩杆1423的连接,并防止第二圆盘从第四通孔中掉下。
上述通过将绑带141穿设在第二伸缩杆1423上的第四通孔中,并利用尺寸大于第二通孔孔径的第二圆盘将绑带141连接在第二伸缩杆1423上,能够使绑带141在第二伸缩杆1423中自由转动,并避免出现因调节第二伸缩杆1423的高度时绑带141随第二伸缩杆1423的转动而转动。
以下对该用于观测动物活动的观测装置与动物的头部固定的具体使用方法进行说明。
在使用前,将固定件133通过外科手术固定在动物的头部;具体的,可采用打颅钉或者用牙科水泥进行固定;其中,打颅钉或者用牙科水泥进行固定的具体实施过程可参见现有技术,且可实现相同或相似的技术效果,在此不再赘述;而在使用时,为了方便安装并减少动物的不适,可以先对动物进行气体麻醉,然后将动物的头部穿过中间两个绑带141之间的空隙,左右前肢分别穿过两侧和中间绑带141的之间的空隙,具体可参见图9,图9为本申请一实施例提供的绑带与动物身体固定时的示意图,然后对动物的头部进行固定;具体的,将固定件133卡入限位槽135中,并将两个固定旋钮1325拧好以将固定件133与球体平台1323固定;然后根据动物头部的当前位置调节限位件1312,以将第一伸缩杆1311固定在高度合适的位置,并调节夹持臂锁紧阀1326,至球体平台1323的角度和位置高度合适,从而使动物的头部能够正常活动;将动物的头部固定之后,将滑动杆1421调整到支撑平台121上合适的位置并通过固定块1422固定,旋转第二伸缩杆1423以使第二伸缩杆1423朝向远离支撑平台121的方向移动,进而收紧绑带141,以使该支撑平台121与动物的身体固定,进而通过动物的身体同时带动支撑平台121移动,降低动物头部因带动支撑平台121移动而发生骨折的概率;之后待动物清醒后开始实验。
具体的,上述所涉及的动物具体可为小鼠;当然,在其它实施例中,上述动物也可为其他类似的爬行类动物、啮齿类动物上或更大型的哺乳动物上,比如狗、猫等。
上述所提供的用于观测动物活动的观测装置,不仅体积小巧,重量轻;且便宜实惠;同时,该装置对场地要求较小,即使在很狭小的空间下也能使用;且该装置可以放在已有的各种各样的平面场地中,无需另做特制的场地;另外,该装置的结构简单可靠,没有复杂的电路,方便使用、清洗、维护、维修或者零件的更换。
需要说明的是,本申请所涉及的观测组件不限于现有技术中的观测设备,该可以是其它操作设备,比如电机、摄像机等,本实施例对此并不加以限制。
以上仅为本申请的实施方式,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
