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 have important practical value to the clinical diagnosis and treatment of urinary dysfunction disease, and to the physiology that urinates, neurourology, Gynecological Urology and relevant pharmaceutical research, also there is very important scientific research value.At present, the index that conventional Urinary functional test is directly measured is bladder and urethra, the interior pressure of rectum, urinary flow, urine volume.The most frequently used is have wound urodynamic study method: insert pressure-measuring pipe and directly measure the change of intravesical pressure, Simultaneously test urinary flow; Urethra each section of pressure distribution situation measured by the pressure-measuring pipe of constant speed traction constant current perfusion; Utilize AG, PQ figure to analyze, diagnose the illness.The method ensure that the degree of fitting of measurement result and truth to greatest extent.
In order to carry out bladder pressure and urethra pressure measuring, usually pouring liquid need be carried out with liquid to bladder and urethra, need two-chamber pressure catheter during perfusion, utilize principle that on equal pitch contour, connected loop pressure is equal to carry out the measurement of human bladder's pressure and urethra pressure everywhere.At present, conventional pressure transmission is the two-chamber pressure-measuring pipe by being inserted in human bladder, and this double lumen tube has two single chamber link A and B respectively, and when measuring bladder pressure, perfusion fluid enters bladder from one end A of two-chamber pressure-measuring pipe.In order to reduce patient suffering, the comparatively thin and made of soft of the diameter that this two-chamber pressure-measuring pipe mostly designs, as 6Fr, 8Fr, 9Fr, 12Fr etc., owing to two of a double lumen tube chamber will be divided into two independently single chambeies separately, connects with two connection tubes respectively.The material of double lumen tube is PVC macromolecular material, generally can only change two-chamber into two single chambeies by bonding method.Through studying the existing product of existing market and the method for attachment of external Patents conduit, the splitter of general double lumen tube has following several method of attachment:
1) with two thin connecting ducts as switching, the two-chamber end that one end inserts double lumen tube is respectively bonding again, and it is bonding that the other end inserts two single lumen catheters respectively, then be adhesively fixed by the upper and lower covers of splitter.This designs thin connection tube and inserts more difficult, and bonding process is many, and technique comparatively 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 larger double channel catheter of two-chamber mouth, and the two-chamber urethra pressure-measuring pipe used urodynamic analysis instrument is improper.
3) inserted on double lumen tube by two ductules in advance, bamboo product one splitter mould, the double lumen tube connected is injection molded into splitter as down part by injection machine, and this mode requires high, high temperature resistant to the material of double lumen tube, high stability, inapplicable existing conduit.
Summary of the invention

Object of the present invention is achieved through the following technical solutions: a kind of two-chamber urethra pressure-measuring pipe connecting device, it comprises splitter, single lumen catheter A, single lumen catheter B, double lumen tube and plug, the inside of described splitter is provided with a sprue and two sub-runners be all communicated with sprue, described sprue and two sub-runners all have the inner that an outer end being communicated with space outerpace and are positioned at splitter inside, the inner of sub-runner A in two described sub-runners is communicated with the inner of sprue, the inner of another sub-runner B in two described sub-runners is communicated with sprue from the side-walls of sprue, in sprue, double lumen tube is installed, and the degree of depth that double lumen tube stretches into sprue inside is greater than sprue and the degree of depth residing for sub-runner B connectivity part, be provided with two axis in described double lumen tube to be arranged in parallel and the tract mutually separated, on the sidewall of the tract A of sub-runner B, the side opening being communicated with sub-runner B is provided with in two described tracts, the plug of shutoff tract A is provided with in the tract A that tract A stretches between the port of sprue and this side opening, single lumen catheter A and single lumen catheter B is separately installed with in sub-runner A and sub-runner B.
Described sprue is the trumpet type reduced gradually along internal diameter from outside to inside, is provided with the sleeve pipe in gap between seal primary flow passage and double lumen tube between the outer end of sprue and double lumen tube.
Described sprue and sub-runner A are for being coaxially set, and the angle between described sub-runner B and sprue is 20 ° ~ 60 °.
Adopt the method for attachment of described a kind of two-chamber urethra pressure-measuring pipe connecting device, it comprises the following steps: form a plug with fluid sealant and block tract A, and described side opening is offered on the sidewall of double lumen tube, double lumen tube is inserted the sprue of splitter, side opening is communicated with sub-runner B, then inserts with sleeve pipe fixing; Then single lumen catheter A and single lumen catheter B inserted respectively sub-runner A and sub-runner B and fix, completing the connection of two-chamber urethra pressure-measuring pipe with this.
The present invention has the following advantages: the present invention by opening side opening and arranging the technical method that plug combines on double lumen tube, and the defect that the production method of so ingenious that to evade existing two-chamber pressure-measuring pipe exists, has technique simple, easy to make, yield rate is high, and production efficiency is high, practical; And structure of the present invention is simple, properties of product are reliable, can meet clinical applicable requirement completely.
