Abstract
胃肠双重造影用产气胶囊,属X线胃肠双重造
影诊断用产气剂剂型改变。胶囊用明胶制成:在胃内
酸性环境中三分钟崩解,释放出所含药。囊内药为枸
橼酸(柠檬酸)+碳酸氢钠。胶囊崩解后,反应释放出
二氧化碳气体。
Description
本发明涉及一种100%在胃内产生气体的产气剂,尤其是在低张气钡双重造影时效果明显。
目前,常用的双重造影产气剂为片剂和粉剂两种;将产气片或产气粉放于口腔内冲服,产生气体,但是在服用过程中,由于剂型因素,使产气粉约30%在口腔及食道内产气,甚至100%在口腔内产气;致使胃内气体太少,达不到展平胃壁的目的,使双重造影效果较差,同样,产气片一般口服20片以上,其内不仅含较多的添加剂,在胃内产生伪影,且常因受潮,气体提前释放,在胃内产气量不足,影响双重造影的效果。
本发明的目的是提供一种产气剂,它不仅能够在胃内提供足量的气体,而且服用方便,用量较小。
本发明的目的是这样实现的:用明胶制作可互相部份***的胶囊,将产气用的药粉碳酸氢钠和枸橼酸密封在胶囊内,平时就封装塑料板上使其防潮;在使用中可根据需要服用4-6粒。当服用时可与肌注平滑肌松驰剂同时进行,服用后大约在8-10分钟可在胃内100%的产生气体;同时肌注的平滑肌松驰剂也发生作用,明胶制成胶囊在胃内酸性环境中2分钟内迅速崩解,释放出其中的碳酸氢钠和枸椽酸;遇水发生反应,在胃内释放出100%的二氧化碳,产生在气体可与钡剂在胃体平滑肌松驰的情况下显示胃小区及胃小沟。
由于采用了胶囊剂型,使其服用方便,对人口咽部刺激消失,并且能够100%的在胃内产生气体,达到双重造影的目的。
在图1、图2及图3所示中,分别为分离图、正位图、透视图;胶囊壳为标准型胶囊壳,辱约几微米,其中一半直径较另一半略小,并可互相套入约3mm;产气药粉装于胶囊内,并密封。
