环咽肌失弛球囊扩张治疗装置设计

Design of balloon dilatation device for achalasia of cricopharyngeal muscle

咽食管运动功能如果出现障碍,在临床上即表现为吞咽困难。目前国际上对于吞咽障碍的治疗方法大致分为2类:球囊扩张治疗法和电刺激治疗法。环咽肌失弛球囊扩张治疗装置设计是以球囊扩张治疗原理为基础,通过球囊扩张的压力带动环咽肌收缩舒张以达到治疗的目的。在工作时,通过电子充水泵向球囊导管内充水即加压,到达一定的气囊扩张压力后,排水阀按规定的速度排水,直至到达一定的气囊收缩压力后,再次向气囊导管内充水。如此反复操作,达到对患者环咽肌的循环压迫,促使环咽肌收缩舒张,达到使患者能逐渐自主进行吞咽的目的。该装置操作简单,安全可靠;可以由医生简单操作,自动定时、定量向球囊充水进行球囊扩张,以达到治疗环咽肌失弛的目的。

Obstacles in pharyngoesophageal function are characterized clinically by dysphagia. At present, the treatment for dysphagia is broadly divided into two ways： balloon expansion therapy and electrical stimulation therapy. Balloon dilatation device for achalasia of cricopharyngeal muscle is design based on the principle of expansion treatment to stimulate cricopharyngeal muscle contraction and dilatation through the pressure of balloon dilation. At work, the water was filled in balloon catheter through the electronic charge pump to pressurize to reach a certain pressure of the balloon dilatation, and the drain valve drained water at prescriptive speed until it reaches a certain contraction of the balloon pressure, followed by water filling in the balloon catheter. This operation was repeated operation, resulting in a compression cycle to cricopharyngeal muscle, promote its contraction and dilatation. Patients can gradually restore autonomy of swallowing. The device is easy to operate, safe and reliable. The doctor can fill water in the balloon catheter at certain time and quantity to achieve the treatment of achalasia of cricopharyngeal muscle.
