Description

一种医用大便采集器 技术领域
本发明涉及一种检验科用医疗器械，特别是一种医学检验用大便采样装置。
背景技术
在临床实践中，大便检验是一种常规的检验方式，由于缺乏专用的大便采样器具，目前一般采用棉签或竹签作为采样器具，但是，在采样的过程中，由于大便比较脏污，而使用棉签或竹签进行采样，则必然使采样人员离大便很近，因而会影响采样人员的身心健康，另外，采样完毕后，粘在棉签或竹签上的大便样本很快就会被风干，会严重影响检验结果的准确性。
发明内容
本发明要解决的问题是：提供一种结构简单、采样距离远因而不会影响采样人员身心健康且密闭性好和能提高检验结果准确性的医用大便采集器。
为了解决上述问题，本发明的医用大便采集器，包括左半试管本体和右半试管本体，所述左半试管本体和右半试管本体之间设有转轴，转轴下方的左半试管本体和右半试管本体之间设有压缩弹簧，所述左半试管本体的外壁上固定有第一连接块，所述右半试管本体上固定有第二连接块，所述第一连接块内插入有第一连杆，所述第一连接块与第一连杆之间为螺纹连接，所述第二连接块内插入有第二连杆，所述第二连接块与第二连杆之间也为螺纹连接，还包括一个用于将左半试管本体和右半试管本体的开口塞住的橡皮塞。
为了方便握紧第一连杆和第二连杆，本发明的医用大便采集器，所述第一连杆为L形，所述第一连杆的末端固定有第一把手，所述第二连杆的末端固定有第二把手。
本发明取得的有益效果是：(1)结构简单；(2)具体采样的时候，将第一连杆、第二连杆分别与第一连接块、第二连接块相连接，然后向前推动左半试管本体，向后拉动右半试管本体，使左半试管本体和右半试管本体沿转轴转动并使左半试管本体和右半试管本体的下半部分离，再将左半试管本体和右半试管本体置于需采样的大便上，最后停止对第一连杆和第二连杆用力，在压缩弹簧的收缩力的作用下，左半试管本体和右半 试管本体逐渐对接并闭合，左半试管本体和右半试管本体在对接和闭合的过程中，会将少许的大便夹入左半试管本体和右半试管本体内，从而完成大便样本的采样，由于第一连杆和第二连杆的尺寸较长，因而样本采集人员可以距离需要采样的大便较远，从而大大降低对采样人员身心健康的损害；(3)采样完毕后，将橡皮塞塞入左半试管本体和右半试管本体的开口处，从而将左半试管本体和右半试管本体密封起来，避免大便样本被风干，从而提高检验结果的准确性；(4)第一连杆的末端固定有第一把手，第二连杆的末端固定有第二把手，便于握紧第一连杆和第二连杆。
附图说明
图1是本发明的结构示意图。
图中：1、转轴，2、左半试管本体，3、第一连接块，4、压缩弹簧，5、右半试管本体，6、橡皮塞，7、第一连杆，8、第一把手，9、第二连接块，10、第二连杆，11、第二把手。
具体实施方式
如图1所示，本发明的医用大便采集器，包括左半试管本体2和右半试管本体5，所述左半试管本体2和右半试管本体5之间设有转轴1，转轴1下方的左半试管本体2和右半试管本体5之间设有压缩弹簧4，所述左半试管本体2的外壁上固定有第一连接块3，所述右半试管本体5上固定有第二连接块9，所述第一连接块3内插入有第一连杆7，所述第一连接块3与第一连杆7之间为螺纹连接，所述第二连接块9内插入有第二连杆10，所述第二连接块9与第二连杆10之间也为螺纹连接，还包括一个用于将左半试管本体2和右半试管本体5的开口塞住的橡皮塞6；所述第一连杆7为L形，所述第一连杆7的末端固定有第一把手8，所述第二连杆10的末端固定有第二把手11。
本发明的医用大便采集器，结构简单，具体采样的时候，将第一连杆7、第二连杆10分别与第一连接块3、第二连接块9相连接，然后抓紧第一连杆7和第二连杆10，向前推动左半试管本体2，向后拉动右半试管本体5，使左半试管本体2和右半试管本体5沿转轴1转动并使左半试管本体2和右半试管本体5的下半部分离，再将左半试管本体2和右半试管本体5置于需采样的大便上，最后停止对第一连杆7和第二连杆用力10，在压缩弹簧4的收缩力的作用下，左半试管本体2和右半试管本体5逐渐对接并闭合，左半试管本体2和右半试管本体5在对接和闭合的过程中，会将少许的大便夹入左半试管本体2和右半试管本体5内，从而完成大便样本的采样，由于第一连杆7和第二 连杆10的尺寸较长，因而样本采集人员可以距离需要采样的大便较远，从而大大降低对采样人员身心健康的损害。
采样完毕后，将橡皮塞6塞入左半试管本体2和右半试管本体5的开口处，从而将左半试管本体2和右半试管本体5密封起来，避免大便样本被风干，从而提高检验结果的准确性。
第一连杆7的末端固定有第一把手8，第二连杆10的末端固定有第二把手11，便于握紧第一连杆7和第二连杆10。
