Description

一种动物细胞组织培养装置及培养方法 技术领域
本发明涉及动物细胞组织培养的技术领域，特别涉及一种动物细胞组织培养装置及培养方法。
 背景技术
动物细胞培养就是从动物体中取出相关的组织、将组织其放在培养液中让这些组织细胞生长和增殖得到新细胞的方法，随着基因工程和其他细胞工程技术的发展，细胞培养技术已成为转基因技术、生物制药及其他许多技术的基础，在现代生物技术中发挥着重要的作用。
人工通过刮板将刮下的动物组织细胞放置在培养皿中部，由于动物组织细胞在增殖生长过程中需要消耗培养液中的营养成分，故培养液中营养成分浓度在动物组织细胞培养过程中自培养皿中部向培养皿四周逐渐减小，培养液内部营养成分存在不均匀的问题，从而影响动物组织细胞增殖效果。
由于动物组织细胞在培养过程中可能需要及时补充培养液，传统的培养液补充过程中需要人工打开培养装置直接向培养皿中加入培养液，这个过程中可能会造成空气中的杂菌进入到培养皿中，导致杂菌进入培养液影响动物组织细胞生长，甚至有害杂菌可能会造成动物组织细胞增殖停止，影响动物组织细胞培养结果。
 技术问题

优选的，所述的导引板与连接管内壁之间上下对称安装有连接弹簧，导引板与连接管内壁接触的部分设置有擦拭海绵，位于阀门同一侧相邻两个导引板之间安装有导引绳，由于连接管直径较小且较长，故在对连接管进水清洗过程中手动带动导引绳带动导引板在连接管内部往复滑动，进而导引板通过擦拭海绵可以对连接管内壁进行往复擦拭清洗，便于对连接管内部的清理，其中连接弹簧在清洗过程中对导引板起复位作用。
优选的，所述的盖板下端面边缘处设置有矩形凸起，培养框上端面边缘开设有与矩形凸起相配合的密封槽，密封槽与矩形凸起相互配合可以腔体内部起密封作用，避免空气中的杂质进入到腔体内部，影响动物组织细胞生长情况。

第四步：观察取出：通过显微放大镜观察动物组织细胞的生长情况，当动物组织细胞培养结束后打开盖板将培养皿取出，工作结束。
本发明的有益效果在于：1.本发明设计的培养框中分为四个腔体可以在动物细胞组织传代培养过程中同时对四个培养皿中的动物细胞组织进行增殖培养，提高动物细胞组织增殖培养效率；在晃动机构中，转动圆盘带动竖直移动块在环形调节板上上下往复移动，进而竖直移动块通过晃动杆带动承托盘转动过程中同步带动承托盘晃动，从而对培养皿中的培养液进行晃动摇匀处理；在上料机构中，打开密封塞经过进料口向上料筒内部灌入培养液，再将密封塞合上，根据各个培养皿中所需要培养液的多少，打开阀门通过注射筒挤压空气将培养液通过分液管与连接管相互配合将培养液泵入培养皿中，在整个上料过程中未打开盖板，从而减少杂菌进入腔体内部的可能，减少杂菌污染动物组织细胞培养的可能性。
2.本发明设计的上料机构中，当各个培养皿中需要的培养液相同时，同步打开阀门通过注射筒挤压空气将培养液通过分液管与连接管相互配合将培养液泵入培养皿中，当各个培养皿中所需要培养液不同时，分别打开阀门通过注射筒挤压空气将培养液通过分液管与连接管相互配合将培养液泵入培养皿中，通过调节阀门既可以同步向培养皿中泵入培养液，又可以分别向培养皿中泵入培养液，适用性更广。

 具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
如图1、图3以及图4所示，一种动物细胞组织培养装置，包括培养平台1、连接柱2、培养框3、盖板4、晃动机构5、承托盘6、培养皿7以及上料机构8，所述的培养平台1上端面四个拐角处安装有连接柱2，四个连接柱2上端面共同安装有培养框3，培养框3内部通过十字形隔板分隔成四个腔体，四个腔体内部以及培养平台1上端面共同安装有晃动机构5，晃动机构5上端安装有承托盘6，承托盘6上卡接有培养皿7，培养框3上端面安装有盖板4，盖板4上端面安装有上料机构8，盖板4上端面且位于腔体的正上方安装有观测腔体的显微放大镜41，培养框3侧壁四个拐角处开设有观察窗42。
如图3以及图4所示，所述的盖板4下端面边缘处设置有矩形凸起32，培养框3上端面边缘开设有与矩形凸起32相配合的密封槽31，密封槽31与矩形凸起32相互配合可以对腔体内部起密封作用，避免空气中的杂质进入到腔体内部，影响动物组织细胞生长情况。
如图6所示，所述的培养皿7内壁上卡接有环形板71，当培养皿7内部动物组织细胞与培养液加入结束后将环形板71卡接在培养皿7内壁，避免培养皿7晃动过程中培养液从培养皿7中溅出，造成培养液的浪费，同时保证腔体内部的环境卫生。
如图2、图4、图5以及图6所示，所述的晃动机构5包括晃动电机51、转轴52、转动圆盘53、环形调节板54、竖直移动块55、竖直连轴56、晃动杆57以及转动套筒58，其中所述的晃动电机51通过电机座安装在培养平台1上端面中部，培养框3下端且位于四个腔体中部通过轴承贯穿安装有转轴52，晃动电机51输出轴与四个转轴52之间均通过齿轮啮合方式相互连接，转轴52上端面安装有转动圆盘53，腔体底部中间位置安装有环形调节板54，环形调节板54上端面周向均匀开设有多个调节凹槽541，转动圆盘53上端上下贯穿滑动设置有竖直移动块55，且竖直移动块55下端抵靠在环形调节板54上，转动圆盘53上端面中部通过轴承安装有竖直连轴56，竖直连轴56上端面通过球铰安装有承托盘6，竖直连轴56中部自左向右开设有贯通槽561，贯通槽561内部通过铰轴安装有转动套筒58，转动套筒58内部滑动设置有晃动杆57，承托盘6下端面以及竖直移动块55上端面均水平滑动设置有移动连块59，晃动杆57上端通过铰链安装在上方的移动连块59上，晃动杆57下端通过铰链安装在下方的移动连块59上。
如图4以及图6所示，相邻所述的调节凹槽541的深度不同，使得竖直移动块55在上下移动过程中获得不同振幅，进而通过晃动杆57带动承托盘6获得不同摇晃幅度，从而保证培养皿7获得不同摇晃幅度使得培养液内部营养成分分布更加均匀。
如图1所示，所述的上料机构8包括上料柱81、上料筒82、注射筒83、分液管84以及连接管85，其中所述的上料柱81安装在盖板4上端面中部，上料筒82通过螺纹连接方式安装在上料柱81上端，上料筒82左侧开设有安装密封塞87的进料口，上料筒82上端面安装有与上料筒82相贯通且带有刻度的注射筒83，上料筒82下端面周向均匀安装有多个与上料筒82相贯通的分液管84，盖板4上端面且位于四个培养皿7正上方也安装有与腔体相贯通的分液管84，上下两个相邻分液管84之间卡接有带有阀门86的连接管85。
具体工作时，通过人工向装有动物组织细胞的培养皿7中加入培养液，将盖板4取下后再将培养皿7卡接在承托盘6内部，最后将盖板4合上，此时动物组织细胞在培养皿7内部增殖生长，通过显微放大镜41与观察窗42观察动物组织细胞的生长情况，由于动物组织细胞在增殖生长过程中需要消耗培养液中的营养成分，培养液中营养成分浓度自培养皿7中部向培养皿7四周逐渐减小，导致培养液内部营养成分不均，影响动物组织细胞生长，故在动物组织细胞培养过程中晃动电机51启动通过齿轮啮合方式带动转轴52转动，转轴52通过转动圆盘53带动竖直移动块55同步转动，竖直移动块55通过晃动杆57带动承托盘6绕着竖直连轴56转动，承托盘6转动过程中竖直移动块55通过与调节凹槽541相互配合带动晃动杆57在转动套筒58内部上下往复滑动，进而在承托盘6转动过程中通过晃动杆57同步带动承托盘6晃动，从而将培养皿7中的培养液晃动摇匀，避免培养液内部营养成分存在不均匀的问题，影响动物组织细胞增殖效果，其中上下两个移动连块59可以补偿晃动杆57在水平方向的位移。
当培养皿7中的培养液不足时，打开密封塞87经过进料口向上料筒82内部灌入培养液，再将密封塞87合上，根据各个培养皿7中所需要培养液的多少，当各个培养皿7中需要的培养液相同时，同步打开阀门86通过注射筒83向上料筒82挤压空气，挤压的空气通过分液管84与连接管85相互配合将培养液泵入培养皿7中，当各个培养皿7中所需要培养液不同时，分别打开阀门86通过注射筒83挤压空气将培养液通过分液管84与连接管85相互配合将培养液泵入培养皿7中，避免通过人工打开盖板4直接向培养皿7中加入培养液过程中引入杂菌的可能性，其中注射筒83上标有刻度可以实现向培养皿7中定量加入培养液，上料筒82与连接管85通过可拆卸方式分别安装在上料柱81与分液管84上，便于上料筒82与连接管85后续的快速拆卸清洗。
如图7所示，所述的上料筒82内部下端面中部通过轴承安装有转动轴821，转动轴821圆周面下方均匀设置有多个搅拌爪822，转动轴821上方安装有一号锥齿轮823，上料筒82右侧壁上方通过轴承安装有联动轴824，联动轴824左端面安装有与一号锥齿轮823相啮合的二号锥齿轮825，联动轴824上安装有传动齿轮826，上料筒82上端上下贯穿设置有滑动板827，滑动板827上端抵靠在注射筒83伸缩端下端面，滑动板827前端面下端设置有与传动齿轮826相配合的齿条，滑动板827底部设置有水平的固定凸起，滑动板827通过固定凸起与上料筒82内壁之间安装有复位弹簧杆828，培养液在灌入上料筒82内部后由于培养液处于静置状态，培养液内部的营养成分可能会发生沉淀的现象导致培养液内部存在营养物质不均匀的问题，故当按压注射筒83向培养皿7中泵入培养液时，此时滑动板827同步下移，滑动板827通过齿条带动传动齿轮826转动，进而传动齿轮826带动联动轴824转动，联动轴824通过一号锥齿轮823与二号锥齿轮825相互配合带动转动轴821转动，从而转动轴821带动搅拌爪822对培养液进行搅匀处理，提高培养液内部营养物质的均匀性，其中复位弹簧杆828对滑动板827起复位作用。
如图3以及图6所示，四个所述的腔体内壁且位于承托盘6外侧均安装有内部为环形件61，且环形件61为方形板上端面开设有圆通槽的结构，环形件61内壁上均匀安装有多个承托弹簧杆62，承托弹簧杆62远离环形件61的一端通过球铰安装有与承托盘6相配合的承托块63，环形件61通过承托弹簧杆62与承托块63相互配合可以对承托盘6起限位承托作用，避免承托盘6在竖直连轴56上单点受力不稳定性，增加承托盘6在晃动过程中稳定效果。
如图8、图9以及图10所示，所述的连接管85内部均匀设置多个开设有导引孔的导引板851，盖板4下端面且位于下方的分液管84出口处通过支撑架安装有引流板852，引流板852上端面设置为锥形结构，引流板852下端设置为伞型结构，伞型结构上端面周向均匀设置有多个引流槽853，下端为伞形结构的引流板852通过与引流槽853相互配合可以对培养液起到导流作用，避免培养液在进入培养皿7时分布不均匀，造成动物组织细胞获得营养成分不均匀的问题，影响动物组织细胞的增殖效果，导引板851可以减小培养液进入培养皿7中的冲击力，避免培养液的冲击力过大冲散动物组织细胞，影响动物组织细胞的培养情况。
如图9所示，所述的导引板851与连接管85内壁之间上下对称安装有连接弹簧854，导引板851与连接管85内壁接触的部分设置有擦拭海绵855，位于阀门86同一侧相邻两个导引板851之间安装有导引绳856，由于连接管85直径较小且较长，故在对连接管85通水进行清洗过程中手动拉动连接管85最外侧的两个导引板851移动，进而两个导引板851通过导引绳856带动剩余的导引板851在连接管85内部往复滑动，从而导引板851通过擦拭海绵855可以对连接管85内壁进行往复擦拭清洗，便于对连接管85内部的清理，其中连接弹簧854在清洗过程中对导引板851起复位作用。
如图11所示，本发明还提供了一种动物细胞的培养方法，包括以下步骤：第一步：放置处理：向装有动物组织细胞的培养皿7内部加入培养液，将盖板4取下后再将培养皿7卡接在承托盘6内部，最后将盖板4合上。
第二步：晃动处理：晃动电机51启动通过齿轮啮合方式带动转轴52转动，转轴52通过转动圆盘53带动竖直移动块55同步转动，竖直移动块55通过晃动杆57带动承托盘6绕着竖直连轴56转动，承托盘6转动过程中竖直移动块55通过与调节凹槽541相互配合带动晃动杆57在转动套筒58内部上下往复滑动，进而在承托盘6转动过程中通过晃动杆57同步带动承托盘6晃动，从而将培养皿7中的培养液晃动摇匀。
第三步：上料处理：当培养皿7中的培养液不足时，打开密封塞87经过进料口向上料筒82内部灌入培养液，再将密封塞87合上，根据各个培养皿7中所需要培养液的多少，打开阀门86通过注射筒83向上料筒82挤压空气，挤压的空气通过分液管84与连接管85相互配合将培养液泵入培养皿7中，注射筒83按压过程中此时滑动板827同步下移，滑动板827通过齿条带动传动齿轮826转动，进而传动齿轮826带动联动轴824转动，联动轴824通过一号锥齿轮823与二号锥齿轮825相互配合带动转动轴821转动，从而转动轴821带动搅拌爪822对培养液搅匀处理。
第四步：观察取出：通过显微放大镜41观察动物组织细胞的生长情况，当动物组织细胞培养结束后打开盖板4将培养皿7取出，工作结束。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。

  9. 根据权利要求1所述的一种动物细胞组织培养装置，其特征在于：所述的动物细胞组织培养装置对动物细胞的培养方法，包括以下步骤：
    第一步：放置处理：向装有动物组织细胞的培养皿(7)内部加入营养液，将盖板(4)取下后再将培养皿(7)卡接在承托盘(6)内部，最后将盖板(4)合上；
    第二步：晃动处理：晃动电机(51)启动通过齿轮传动方式带动转轴(52)转动，转轴(52)通过转动圆盘(53)带动竖直移动块(55)在环形调节板(54)上上下往复移动，进而竖直移动块(55)通过晃动杆(57)带动承托盘(6)转动过程中同步带动承托盘(6)晃动，从而对培养皿(7)中的营养液进行晃动摇匀处理；
    第三步：上料处理：当培养皿(7)中的营养液不足时，打开密封塞(87)经过进料口向上料筒(82)内部灌入营养液，再将密封塞(87)合上，根据各个培养皿(7)中所需要营养液的多少，打开阀门(86)通过注射筒(83)挤压空气将营养液通过分液管(84)与连接管(85)相互配合将营养液加入培养皿(7)中；
    第四步：观察取出：通过显微放大镜(41)观察动物组织细胞的生长情况，当动物组织细胞培养结束后打开盖板(4)将培养皿(7)取出，工作结束。
