Design,Preparation And Evaluation Of New Salpingography Instrument

At this stage,due to the accumulation of factors in work,life and environment,the number of female infertility patients has increased year by year,and the tubal blockage factor accounts for a large part.Therefore,the method of tubal blockage examination is very important.In the examination method,the uterus fallopian tube Contrast is the most popular and most standard method of application.At present,the clinical use of hysterosalpingography,the balloon catheter method is commonly used,but there are many problems in this method,and the imaging experience that brings pain to the angiographic patient needs to be solved urgently.This article first introduces the status quo of diagnosis and treatment of tubal obstruction at home and abroad,and points out the points of interest in this study,as well as the improvement of tubal angiography equipment,and then determines the final scheme through continuous mechanical model design,and completes the design and processing of molds.The contrast-imaging apparatus structure includes a conical body,a contrast-imaging rod,a reflux prevention structure and a sliding positioning device.The tip of the conical body is located at the far end of the contrast-imaging rod,and the front end of the conical body is provided with a flow outlet of contrast agent or liquid.The distal end of the contrast rod is coordinated with the conical body,and the base and the backflow prevention structure are coordinated and connected to the proximal end of the contrast rod.The load-bearing contrast bar is hollow structure,which is the internal channel for contrast agent circulation.In addition,the contrast-imaging device is designed with a sliding positioning device relative to the load-bearing contrast-imaging rod.The positioning device is used to fix the position of the safe fallopian tube contrast-imaging device during the contrast-imaging.Then the mold design and processing are completed,the model samples are prepared,and the performance tests of the samples are completed.Finally,the clinical trial was completed in the hospital,which proved that the contrast instrument designed by the institute can complete accurate angiography and can be superior to the balloon catheter under individual indicators.Theinstrumenthas obvious improvement effect on the current market for fallopian tube angiography instruments,and can be applied inthe clinic.It can significantly reduce the pain of patients with tubal angiography,reduce the contrast time and postoperative complications.
