Abstract

本实用新型涉及医用造影剂,用于胃肠道X光造影,测定胃肠道固体排空时间。其外形为球形或胶囊形,用无毒医用高分子聚合物作外壳,内装硫酸钡粉,或者用硫酸钡粉与无毒医用高分子聚合物浇铸一体。硅橡胶为首选高分子聚合物。它口服方便、表面光滑、不易被人体消化吸收,无毒无刺激,与胃肠道摩擦阻力小,能方便地测定并准确地反映胃固体排空时间和口-***时间等。

Description

胃肠道造影胶丸
本实用新型涉及医疗用品,进一步讲是一种用于胃肠道X光造影用的医用造影剂。
目前,测定胃固体排空试验,须采用放射性同位素标志食物进行扫描,手续繁琐且需相当的医疗设备条件,基层医院无法开展,超声波诊断仅能大致测定液体排空,临床意义不大,尚没有临床实用的简单易行的测定胃排空和口——***时间的方法。曾有人设计短塑料管内装硫酸钡粉,现称管式固体造影剂。管式固体造影剂有明显缺点:1.口服不方便,需外套可溶性胶囊;2.管式造影剂与胃肠道摩擦阻力大,不能真实反映胃排空和口——***时间;3.管式造影剂外形不光滑,有引发溃疡、憩室等穿孔之虞。
本实用新型的设计目的在于克服已有技术中的不足之处,而提供一种口服方便、表面光滑,不易被人体消化吸收的无毒无刺激的,能准确反映胃肠道固体排空时间的固体造影剂,或称固体造影胶丸。
本实用新型的设计目的可以通过以下措施来达到。
胃肠道造影胶丸,制成球形或胶囊形,用无毒医用高分子聚合物作外壳,壳内装硫酸钡粉,或者用硫酸钡粉与无毒医用高分子聚合物混合浇铸一体。
本实用新型的设计目的还可以通过以下措施来达到:
胃肠道造影胶丸的外壳用硅橡胶材料制作,并制成球形。
胃肠道造影胶丸用硫酸钡粉与与硅橡胶材料混合浇铸一体,制成球形。
本实用新型与已有技术相比具有如下优点:
①口服方便,表面光滑,不易被人体消化吸收,无毒无刺激,与胃肠道摩擦阻力小。
②能方便地测定并准确地反映胃固体排空时间和口——***时间、结肠运转时间等。
附图的图面说明如下:
图1:本实用新型实施例1的结构示意图剖视图
图2:本实用新型实施例2的结构示意图剖视图
本实用新型下面结合附图和实施例作进一步详述:
实施例1:
图1示出了本实用新型胃肠道造影胶丸的一种结构。用硅橡胶材料制成球形外壳1,内装硫酸钡粉2。外壳壁厚0.8mm,直径为6mm。
实施例2:
图2示出了本实用新型胃肠道造影胶丸的另一种结构。用硫酸钡粉与硅橡胶材料混合后浇铸一体,制成球形,直径为6mm。
上述实施例中的球形胶丸亦可制成胶囊形,即两端为半球形,中部为圆柱形。外壳材料也可用其他无毒医用高分子聚合物,如聚乙烯等。
