Abstract
The utility model relates to the field of medical instruments, in particular to a one-way ureter support pipe. The one-way ureter support pipe is characterized in that the one-way ureter support pipe comprises a pipe body, the pipe body is divided into a pelvis end, a middle section and a bladder end, the pelvis end is curved, a plurality of drainage holes are distributed in the pipe wall of the pelvis end, the tail end of the bladder end is open, the inner diameter of the pipe cavity of the bladder end is larger than that of the pipe cavity of the middle section, a valve ball and a barrier plate are arranged in the pipe cavity of the bladder end, the diameter of the valve ball is larger than the inner diameter of the pipe cavity of the middle section and smaller than the inner diameter of the pipe cavity of the bladder end, and the barrier plate is arranged between the valve ball and an opening of the tail end of the bladder end. The one-way ureter support pipe is simple in structure and can effectively prevent urine from flowing back.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of unidirectional ureter rack tube.
Background technology
Serious problem of existing ureter rack tube ubiquity, after ureter rack tube is inserted, no matter patient lies low or stands when urinating, and intravesical urine can be through the ureter rack tube kidney that backflows.Therefore cause patient's waist distending pain, renal colic, secondary urinary tract infection, more seriously can cause in the course of time hydronephrosis to infect and impaired renal function.
Just because of common ureter rack tube is difficult to occur that urine is backflowed has caused many complication with avoiding after keeping somewhere, so also have its contraindication when having its indication clinically on keeping somewhere ureter rack tube problem, for the patient who has lower urinary tract obstruction, endoureteral stent is inapplicable, because intravesical high pressure will cause VUR, and damage renal function.In the time of can causing controlled micturition while backflowing, obvious lower back is uncomfortable, more may cause upper urinary tract infection.Because kidney is relatively poor to anti-infective ability, when occurring backflowing, may there is pyelonephritis.Pyelonephritis can cause renal scars to form, and causes renal function injury.Even if nonjoinder is infected, when generation aseptic is backflowed, also can cause the generation of reflux nephropathy.While backflowing, may cause renal pelvis pressure to raise, can cause renal pelvis-vein, renal pelvis-sinus renalis, renal pelvis-lymphatic vessel to backflow.Pyelosinous transflow can cause kidney week fibrosis, all urinary cysts of kidney, perinephric abscess, retroperitoneal edema, perirenal tissue's adhesion and stimulate tumor of renal pelvis generation after occurring.
Along with being widely used of ureter rack tube, because urine appears in ureter rack tube after keeping somewhere, backflowing and cause the event of violent lumbago, high heat, severe hematuria, impaired renal function more and more clinically.
There are many urological surgeons to wish to reduce by the ureter rack tube with anti-reflux backflowing that placing rack pipe causes, but up to the present, still do not have the ureter rack tube of real anti-reflux to apply to clinical.Trace it to its cause, because ureter rack tube tube chamber is little, the design of anti-reflux device is difficult to realize or is clinical inapplicable.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of unidirectional ureter rack tube is provided, simple in structure and can effectively prevent that urine from backflowing.
For solving above technical problem, the technical solution of the utility model is: a kind of unidirectional ureter rack tube, its difference is: it comprises body, described body is divided into renal pelvis end, stage casing, bladder end, described renal pelvis end is curl shape, on renal pelvis end tube wall, be distributed with a plurality of conduction holes, the open-ended of described bladder end, the lumen diameter of bladder end is greater than the lumen diameter in described stage casing, in the tube chamber of bladder end, be provided with valve ball and barrier plate, the diameter of described valve ball is greater than the lumen diameter in stage casing and is less than the lumen diameter of bladder end, described barrier plate is between valve ball and bladder end end openings.
By above technical scheme, described barrier plate is "+" type structure or " # " type structure.
By above technical scheme, the lumen diameter of described bladder end is 1.8～2.2 times of described stage casing lumen diameter, and the diameter of described valve ball is 1.2～1.5 times of stage casing lumen diameter.
By above technical scheme, the lumen diameter of described bladder end is 2 times of described stage casing lumen diameter, and the diameter of described valve ball is 1.2 times of stage casing lumen diameter.
Contrast prior art, beneficial features of the present utility model is: this unidirectional ureter rack tube, in the tube chamber of bladder end, be provided with valve ball, when bladder pressure is greater than renal pelvis pressure, the clogging stage casing of valve ball tube chamber, prevention is backflowed.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram;
Wherein: 1-renal pelvis end, 2-stage casing, 3-bladder end, 4-conduction hole, 5-barrier plate, 6-valve ball.
The specific embodiment
Below by the specific embodiment, by reference to the accompanying drawings this utility model is described in further detail.
Please refer to Fig. 1, the unidirectional ureter rack tube of this utility model embodiment, it comprises body, described body is divided into renal pelvis end 1, stage casing 2, bladder end 3, described renal pelvis end 1 is curl shape, on renal pelvis end 1 tube wall, be distributed with a plurality of conduction holes 4, the open-ended of described bladder end 3, the lumen diameter of bladder end 3 is greater than the lumen diameter in described stage casing 2, in the tube chamber of bladder end 3, be provided with valve ball 6 and barrier plate 5, the diameter of described valve ball 6 is greater than the lumen diameter in stage casing 2 and is less than the lumen diameter of bladder end 3, described barrier plate 5 is between valve ball 6 and bladder end 3 end openings.
Concrete, barrier plate 5 is "+" type structure or " # " type structure.
Concrete, the lumen diameter of bladder end 3 is 1.8～2.2 times of described stage casing 2 lumen diameters, the diameter of described valve ball 6 is 1.2～1.5 times of stage casing 2 lumen diameters.
Preferably, the lumen diameter of bladder end 3 is 2 times of described stage casing 2 lumen diameters, and the diameter of described valve ball 6 is 1.2 times of stage casing 2 lumen diameters.
In this utility model embodiment, bladder end tube chamber increases thick and open-ended, and its lumen diameter is about 2 times of body stage casing internal diameter.In increasing thick bladder end tube chamber, a valve ball is set, diameter is about 1.2 times of body stage casing internal diameter, position between valve ball and bladder end end openings arranges a barrier plate, barrier plate is "+" structure or " # " structure, only keep off not dash of valve ball, when bladder pressure is greater than renal pelvis pressure, the clogging stage casing of valve ball tube chamber, stops urine to be backflowed.
Above content is the further description of this utility model being done in conjunction with concrete embodiment, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill of the technical field under this utility model, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
