用于存放干细胞的存放袋
本技术涉及医疗器械
,尤其涉及一种用于存放干细胞的存放袋。
技术介绍
随着医学科技的快速发展,人们对干细胞的重要性的认识也愈加明显,所以干细胞的保存也越来越重要。干细胞的保存期限一般在20年左右,在这期间需要对干细胞进行多次取样检测。现有的干细胞保存袋一般保存在液氮罐中,每次取样时都需将其从液氮罐中取出,这样保存袋内的温度会发生较大变化,从而影响干细胞的储存状态,并且现有的保存袋只有干细胞输入管,取样时需要将干细胞输入管的盖帽去掉,这样易污染干细胞,存在干细胞损毁的风险。经检索,中国专利授权公告号为CN207185760U公开了一种干细胞存放袋,包括袋体,所述袋体由内层袋体和套在内层袋体外的外层袋体构成,外层袋体的内壁与内层袋体的外壁之间留有间隙形成液氮腔,液氮腔内充满液氮,外层袋体的内壁与内层袋体的外壁之间间隔设有连接柱,所述内层袋体上设有干细胞输入管,干细胞输入管穿过外层袋体并与外层袋体密封相接,内层袋体上还设有采集管,采集管穿过外层袋体并与外层袋体密封相接,采集管上设有硅橡胶帽。现有的干细胞存放袋存在以下不足之处:该装置结构复杂 ...
