Description
Technical field
The present invention relates to Medical dual-cavity urethra pressure-measuring pipe, particularly a kind of two-chamber urethra pressure-measuring pipe connecting device and method of attachment.
Background technology
Urodynamics is a urologic subdiscipline.Carry out urodynamic study, not only the clinical diagnosis and treatment of urinary dysfunction disease is had to important practical value, and to the physiology that urinates, neurourology, Gynecological Urology and relevant pharmaceutical research, also have very important scientific research to be worth.At present, the index that conventional urine hydromechanics is directly measured is bladder and urethra, the internal pressure of rectum, urine flow rate, urine amount.The most frequently used is to have wound urodynamic study method: insert pressure-measuring pipe and directly measure intravesical pressure variation, measure urine flow rate simultaneously; The pressure-measuring pipe of constant speed traction constant current perfusion is measured each section of pressure distribution situation of urethra; Utilize AG, PQ figure to analyze, diagnose the illness.The method has guaranteed the degree of fitting of measurement result and truth to greatest extent.
In order to carry out bladder pressure and urethra pressure measuring, conventionally need carry out liquid perfusion to bladder and urethra with liquid, when perfusion, need two-chamber pressure catheter, utilize the principle that on equal pitch contour, connected loop pressure equates to carry out the measurement of human bladder's pressure and urethra pressure everywhere.At present, conventional pressure transmission is by being inserted into the two-chamber pressure-measuring pipe in human bladder, and this double lumen tube has respectively two single chamber link A and B, and while measuring bladder pressure, perfusion fluid enters bladder from one end A of two-chamber pressure-measuring pipe.In order to reduce patient suffering, the diameter that this two-chamber pressure-measuring pipe mostly designs is thin and material is soft, as 6Fr, 8Fr, 9Fr, 12Fr etc., owing to two of a double lumen tube chamber will being divided into two single chambeies independently separately, joins respectively with two connection tubes.The material of double lumen tube is PVC macromolecular material, generally can only change two-chamber into two single chambeies by bonding method.Through the method for attachment research to the existing product of existing market and external Patents conduit, the splitter of general double lumen tube has following several method of attachment:
1) with two thin connecting ducts as switching, one end inserts respectively that the two-chamber end of double lumen tube is bonding again, it is bonding that the other end inserts respectively two single lumen catheters, then be adhesively fixed by the upper and lower covers of splitter.This designs, and thin connection tube insertion is more difficult, and bonding process is many, and technique bothers.
2) splitter particular design, single-endedly still has less outlet, is directly inserted on two-chamber termination.This mode is only applicable to the double channel catheter that two-chamber mouth is larger, and the two-chamber urethra pressure-measuring pipe that urodynamic analysis instrument is used is improper.
3) in advance two ductules are inserted on double lumen tube, then design a splitter mould, on injection machine, the double lumen tube connecting is injection molded into splitter as down part, this mode requires high, high temperature resistant to the material of double lumen tube, high stability, inapplicable existing conduit.
Summary of the invention
