优选的，胶囊内窥镜一半的重量比胶囊内窥镜另一半的重量大0.2-0.6g。
优选的，为了使得胶囊内窥镜的重心和轴心不重合，在所述电池的一侧安装有加重件。优选的，所述加重件为线圈或金属环，所述线圈或金属环缠绕于电池上。优选地，所述加重件的重量为0.2-0.6g。
优选的，为使所述胶囊内窥镜的密度略小于体液的密度，所述胶囊内窥镜的密度略小于水，即1.0kg/m3。
优选的，胶囊内窥镜用于胃部检测。
 有益效果
本发明一种胶囊内窥镜的具体实施方式中，胶囊内窥镜的两半胶囊呈重量不对等，其轴心和重心不重合，胶囊内窥镜在胃中运行时，其可垂直竖立的漂浮于体液之中，由此，则可较为准确地判断出所拍摄的图像或影像在胃中的区域或位置，以帮助准确判定胃各区域的胃壁状况，进一步帮助确诊和治疗。
附图说明
图1为本发明一种胶囊内窥镜的具体实施方式的结构示意图。
本发明的实施方式
参照图1所示，本发明一种胶囊内窥镜的具体实施方式提供了一种自垂式胶囊内窥镜，包括胶囊壳体1以及封装在其中的LED光源2、传感器3、镜头4、镜头罩5和电池6，所述镜头罩5设于镜头4外围，所述电池6分别于LED光源2、传感器3、镜头4电连接，所述胶囊内窥镜以中轴为中心，其中一半胶囊的重量大于另一半胶囊的重量，通过将胶囊内窥镜的重心下移，使得胶囊在体液中运行时保持垂直，镜头4与胶囊的运行方向相平行。如图1所示，本发明一种胶囊内窥镜的具体实施方式中所说的轴心为胶囊内窥镜的几何中心。
为了使得胶囊内窥镜在体液中，特别是在人体胃中运行时，体液中能保持直立垂直地运行，将胶囊内窥镜设置成重心偏移向下，重心和轴心相互不重合，在本实施例中，参照图2所示，所述胶囊内窥镜的轴心在A点，而重心在B点，所述轴心A点和重心B点在同一纵轴Y轴上。当胶囊内窥镜直立漂浮于体液中时，重心B点在轴心A点之下，整个胶囊内窥镜的重心偏下，使其在体液中保持平稳、直立地漂浮，因为拍摄的角度相对稳定，则可从拍摄的图像或影像中判断出所拍的区域，以助于精确地判断胃内各区域的壁面状况。在本发明一种胶囊内窥镜的具体实施方式中，所述胶囊内窥镜的重心和轴心之间的偏差为1mm以内。
为了使得胶囊内窥镜的重心偏移向下，在垂直漂浮于体液中时，所述电池的下半部上装设有加重件7，通过增设于胶囊内窥镜下半部的加重件7，增加胶囊内窥镜下半部的重量，使其垂直浮立于体液中时，重心下移，漂浮平稳，拍摄角度稳定可控，提高了拍摄照片或影像的可识别性。其中，所述加重件7为线圈或金属环，所述线圈或金属环缠绕于电池6上。以线圈或金属环缠绕的方式，安装起来更为方便，可根据胶囊内窥镜的自重进行调整，并且，缠绕于电池上，不影响电池的使用，不占用面积。所述加重件的重量为0.2-0.6g。所述加重件7在胶囊内窥镜的安装方式不受此限，只要能将其加装于胶囊内窥镜上，并使得两半构成重量不对等结构即可。
在本发明一种胶囊内窥镜的具体实施方式中，所述加重件7为线圈时，所述线圈的匝数为20匝。所述胶囊内窥镜的密度为0.8-0.95 kg/m3，其密度略小于水的密度，即小于1.0kg/m3，使其可平稳且垂直地悬浮于体液中。所述胶囊内窥镜主要适用于胃部检测，使得胶囊内窥镜在人体胃液中运动时，保持直立悬浮状态，则通过所拍摄的照片或影像中可判定胃的区域，以判定确定区域上的胃壁面的状况，使得诊断者能清楚判断胃中各位置的病理状况。
在本发明一种胶囊内窥镜的具体实施方式中，所述胶囊内窥镜设有两个镜头，分设于胶囊壳体的两端，所述电池设置于胶囊内窥镜的中部。通过在电池上增设或缠绕线圈或金属环，使得胶囊内窥镜构成上半部和下半部的重量不相等的结构，胶囊内窥镜的重心下移，使其在体液中运行保持直立并平稳。通过分设于胶囊内窥镜两端的镜头，分别拍摄胃内两端的壁面，扩大了拍摄范围，使得拍摄的图像或影像范围更广，以利于全方位判断胃壁内的各种状况。
本发明一种胶囊内窥镜的具体实施方式通过在其半侧边设置加重件，使得两半胶囊呈重量不对等的结构，其轴心和重心不重合，胶囊内窥镜在胃中运行时，其垂直竖立并漂浮于体液之中，由于其重心偏下而保持直立，则可较为准确地判断出所拍摄的图像或影像在胃中的区域或位置，以帮助准确判定胃各区域的胃壁状况，进一步帮助确诊和治疗。所述加重件采用线圈或金属环套设于电池上，其装配简单，且可根据重量要求进行自行调整至合适的重量，不影响其他配件的工作。通过让胶囊内窥镜保持垂直漂浮，亦可在外部磁场作用下，受力向确定方向运行，以拍摄到各角度的图像并传送至外部的检测设备中，进行全方位的检测。另外，通过在两端设置双镜头，取代了原有的单镜头的胶囊内窥镜，通过多角度的拍摄，增大了在胃的拍摄范围。以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
