Description
技术领域
本发明属于中医中药技术领域,涉及一种胃肠道造影剂,具体涉及一种适用于寒热夹杂型肠道易激综合征的造影剂。
背景技术
胃肠道为空腔脏器,常有气体影响,超声从体表探测不易得到满意的声像图,胃肠道疾病的诊断常依靠胃镜和x线钡餐检查。近年来由于胃肠声学造影术及超声内镜两项技术的发展和应用,拓宽了胃肠疾病的诊断范围。超声检查可清晰显示胃肠壁的层次结构,发现胃肠壁肿瘤的部位、大小和形态,估计病变侵犯胃肠壁的程度,特别是了解周围器官的转移情况,弥补胃镜和x线检查的不足,为临床治疗方案的选择提供了可靠的依据。
其中,胃肠超声造影检查法是采用造影剂充盈胃、肠腔,通过改善胃肠的超声内部环境,以利于超声波声束穿透,使胃肠结构和其病变方便更加清晰的显示。
但是,患有肠道易激综合征的患者在服用造影剂时,经常会出现造影剂一两个小时就已经到回盲部的情况,正常情况应当在三到六小时,从而不能够顺利造影。出现这种情况通常是因为胃肠蠕动过快,加速了造影剂位移。因此,针对这一类患者在造影过程中能够抑制胃肠蠕动过快,并且能够顺利造影,成为亟待解决的问题。
发明内容
本发明的目的是提供一种适用于寒热夹杂型肠道易激综合征的造影剂,具有抑制胃肠蠕动过快、辅助钡餐吞咽、滋养胃肠道的优点。
寒热夹杂型肠道易激综合征的症状为:腹中作痛或肠鸣腹泻,便下粘腻不畅,或夹泡沫,或腹泻与便秘交作,烦闷不欲饮食,脘腹喜按,口干。舌红,苔腻,脉弦滑。具体原因分析如下:久病失治或禀赋差异,导致寒热错杂,寒邪留于肠胃,则腹中作痛,肠鸣腹泻,便下粘腻不畅,甚或夹泡沫;寒热错杂,气机失调,故见腹泻与便秘交作;热邪较甚时可见口干,烦闷不欲饮食,寒邪伤阳,则脘腹喜温喜按,舌红苔腻,脉弦滑为寒热惜杂之征。因此,本发明提出以下技术方案。
本发明提供一种适用于寒热夹杂型肠道易激综合征的造影剂,由脂质体和包裹于所述的脂质体内的微泡组成,所述脂质体由如下重量份的组分制成:卵磷脂10~25份、中药载体45~70份;其特征在于所述中药载体由以下重量份数的中药原料配制而成:细辛20~30份、桂枝20~30份、川椒5~10份、黄柏10~15份、秦皮20~30份、老虎刺10~15份、白背叶10~15份、补血草10~15份、余甘子1O~15份、青皮10~15份、厚朴10~15份、乌梅5~1O份。
