Abstract:
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.
