一种产科破膜羊水引流装置
本技术涉及医疗器械
,具体是一种产科破膜羊水引流装置。
技术介绍
破膜能使产妇的宫颈软化、宫口扩张、宫缩加强,在产科,对于过期妊娠、产程延长、羊水过多等情况的产妇,最常用的干预手段是人工破膜,目前人工破膜的方式主要有两种,一种是医护人员先用左手中、食指伸入阴道引导,右手持有齿钳钳夹,撕开胎膜,并用手指将破口扩大,破膜后手指应停留在阴道内,经1~2次宫缩待胎头入盆后再将手指取出,采用此种方式破膜时羊水突然喷出或者羊水外流会污染医护人员的衣物;另一种是向阴道内塞入引流管,管内滑动连接破膜针,破膜后利用引流管对羊水进行引流,由于引流管的直径是固定的,随着胎膜开口的增大,羊水会从引流管外侧流出,这两种破膜方式的引流效果都不好,不利于羊水的收集,所以需要一种新型产科破膜羊水引流装置。
技术实现思路
本技术的目的在于提供一种产科破膜羊水引流装置,它的羊水收集引流效果好,集液布的开口尺寸可以根据胎膜开口和宫颈的增大进行调节,能有效防止羊水污染产床。本技术为实现上述目的,通过以下技术方案实现:一种产科破膜羊水引流装置,包括引流管和破膜针,所述引流管的下端固定有导向块,所述导向块上设有圆孔,所述引流管上分别设有进液孔和出液管,所述出液管上固定有集液管,所述引流管的上部转动连接有均匀分布的第一连杆,所述第一连杆上固定有集液布,所述第一连杆的中部转动连接有第二连杆,所述第二连杆上转动连接有轴套,所述轴套上固定有推拉管,所述推拉管穿过圆孔与导向块滑动连接,所述推拉管内滑动连接有 ...
