Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
It referring to figures 1-3, is a kind of anti-reflux support tube of ureter 100 provided by the utility model.The rami ureterici
Frame pipe 100 is mainly used in the ureter for being placed in human body, for will be in the urine drainage to bladder in kidney.Therefore, the urine output
Pipe holder pipe 100 includes being placed in the intra-ureteral stand tube 10 of human body, and the stand tube 10 is for connecting the kidney for being located at two sides
Dirty and bladder.Therefore, bladder crimping segment 20 and kidney crimping segment 30 are equipped at 10 both ends of stand tube.As shown in Figure 1, rami ureterici
Kidney crimping segment 30 of the frame pipe 100 in kidney one end is in the curly of pigtail, and is distributed on the kidney crimping segment 30
The import 31 for thering are several to be flowed into ureter rack tube 100 for the urine in kidney.It is set in the end of bladder crimping segment 20
The outlet 21 for urine outflow is set, to realize that the urine in kidney is passed through kidney crimping segment by ureter rack tube 100
30 import 31 enters in stand tube 10, and by outlet 21 discharge of the stand tube 10 from bladder crimping segment 20 to drain into
In bladder.The entire tube body of ureter rack tube 100 provided by the utility model has been all made of the production of polyurethane PU material, quality
It is very soft, the also warping resistance with higher at the curling of kidney crimping segment 30, and can restore automatically after bending
Original state.And anti-reflux support tube of ureter 100 provided by the utility model is for the comfort that uses, in the outer of its tube body
Side is provided with hydrophilic gel film layer (not shown), which can be improved 100 outside of ureter rack tube
Smoothness, while reducing stimulation of the ureter rack tube 100 to human body.
Meanwhile ureter rack tube 100 provided by the utility model is to play the role of effective anti-reflux, in wing
Anti-reflux valve 40 is provided at the outlet 21 of the end of Guang crimping segment 20.One end of the anti-reflux valve 40 is coated on bladder volume
The end of tune 20 is equipped with the opening 41 flowed out for urine for sealing outlet 21, the other end.I.e. the utility model is provided
Ureter rack tube 100, should from the urine that kidney drain not from the outlet of bladder crimping segment 20 21 be discharged, but lead to
The adjusting for crossing anti-reflux valve 40 is discharged from the opening 41 of anti-reflux elastic valve 40.It can be with by anti-reflux elastic valve 40
Play the role of anti-reflux.
As shown in Figures 2 and 3, which includes the elasticity that two panels controllable opening 41 is opened and is closed
Diaphragm 42.The flexible sheet 42 is influenced by urine pressure in bladder, to open and be closed opening 41.As shown in figure 3, working as
When intravesical urine pressure is greater than the urine pressure in anti-reflux elastic valve 40, two flexible sheets 42 are by external pressure
Power moves towards, to be closed opening 41.As shown in Fig. 2, when intravesical urine pressure is less than anti-reflux elastic valve 40
When interior urine pressure, two flexible sheets 42 are located remotely from each other by the motive force effect inside anti-reflux elastic valve 40, from
And open opening 41.Therefore, two flexible sheets 42 of the anti-reflux elastic valve 40 can play control opening 41 open and
The effect of closing to realize that intravesical urine will not be flowed into anti-reflux elastic valve 40 by opening 41, and then passes through
Ureter rack tube 100, which backflows, to be returned in kidney.Therefore, ureter rack tube 100 provided by the utility model is rolled up in bladder
Anti-reflux elastic valve 40 is provided on tune 20 realizes the effect of unidirectional drainage, can be effectively prevented intravesical urine
It backflows and returns in kidney, cause the secondary injury to human body.
Specifically, as shown in Figure 1, the bladder crimping segment 20 of ureter rack tube provided by the utility model 100 is also
Curly in pigtail, the surrounding of two flexible sheets 42 is bonded to each other sealing and forms the cavity 43 that can accommodate urine, the cavity
43 front end and the sealing of bladder crimping segment 20 are fixed, to ensure that the urine being discharged at the outlet 21 on bladder crimping segment 20 can
With completely into cavity 43, meanwhile, intravesical urine will not enter rami ureterici from the outlet of bladder crimping segment 20 21
In frame pipe 100.And 41 are open set on the end of cavity 43, for urine to be discharged.The flexible sheet 42 and bladder crimping segment 20 it
Between sealing fixation can be fixed using sealing ring, fixed glue can also be arranged by inside and be fixed on flexible sheet 42
On bladder crimping segment 20.
Further, as shown in Figure 1, the flexible sheet of anti-reflux support tube of ureter provided by the utility model 100
42 width D 1 is 2-4 times of the caliber of the bladder crimping segment 20 of ureter rack tube 100.And the length of the flexible sheet 42 is
2-3 times of 42 width of flexible sheet.The anti-reflux elastic valve 40 of the anti-reflux support tube of ureter 100 is placed in bladder,
The volume of cavity 43 can not be too small, need to guarantee the ability that the anti-reflux elastic valve 40 has certain receiving urine, still
The volume of the cavity 43 can not be excessive, excessive that the anti-reflux elastic valve 40 stimulation bladder will be made to cause to human body not
It is suitable.Meanwhile the thickness control of the flexible sheet 42 is between 0.1mm-0.2mm, thereby may be ensured that flexible sheet 42 have compared with
Good sensitivity can control the ability that opening 41 opens and closes.And the flexible sheet 42 is medical silica-gel film, that is, is had
Preferable elastic opening and closing ability can relatively move to open and close opening 41 with the variation of inside and outside pressure.
A kind of anti-reflux support tube of ureter 100 provided by the utility model is provided in the end of bladder crimping segment 20
Anti-reflux elastic valve 40, the two panels flexible sheet 42 of the anti-reflux elastic valve 40 can be opened with the variation of inside and outside pressure and
It is closed the opening 41 of the anti-reflux elastic valve 40, to play the effect of anti-reflux, guarantees the implantation intracorporal rami ureterici of people
Frame pipe 100 can accomplish effective unidirectional drainage, prevent intravesical urine from turning again in kidney and cause to the secondary of human body
Injury.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
