Description
Technical field
Dress is drained the invention belongs to the field of medical instrument technology more particularly to a kind of urinary tract flow diverter and containing its urinary tract
It sets.
Background technology
At present urethral drainage device be typically using intubation be inserted into bladder in is drained, and for need carry out it is longer when
Between when draining, then connect a drainage bag in intubation outer end, closing device by installation folder in intubation is blocked.The drainage of finished product
Utensil then closes device by the folder in urethral catheterization intubation, drainage bag and urethral catheterization intubation and forms.Above-mentioned utensil starts to drain when in use
Or stopping drainage all by artificial judgment and being operated, and so that the workload of medical staff is increased, usual medical staff will be every 2h
A urinary catheter is pressed from both sides, to keep filling of bladder, but which uses artificial judgment there are still error, and urine accumulation, which is used for a long time, is more than
Bladder rated pressure can cause trauma of bladder, and bladder function atrophy, final loss of function are be easy to cause if urinary catheter is not clamped.In addition
For urgent patient or lack the patient of sensing capability, due to be difficult in practice judge in bladder how whether in expanded state and
It needs to discharge, to prevent the excessively full damage bladder of bladder, generally takes the mode of long-term drainage state, even if drainage device
Folder closes device and is constantly in opening state.Go down for a long time, patient's bladder can be made to be chronically at contraction state and weakens the life of bladder
Function is managed, the recovery of patient's bladder urination function is unfavorable for.
In order to solve the above-mentioned technical problem, urethral catheterization manipulation is carried out in order to facilitate patient or medical staff, done in the prior art
Improvement project, such as the patent of invention that application publication number is CN 107510866A disclose a kind of urological department urethral catheterization device,
In the device middle pipe in form the sliding cavity perpendicular to tube body axial direction；The middle pipe be located at the side of the branch pipe at
The flexible press section of type；The press section, which is located to be fixedly connected in the sliding cavity, is useful for that liquid in control pipe body is logical to be closed
Sliding shoe；In the middle part of the sliding shoe along the tube body axially form for for urine by channel；At the press section
When pressing state, urine in catheter is after pipe flows out to after being flowed through by front tube after preceding connecting tube and by channel
Connecting tube finally flows into drainage bag；When the press section is in unstressed state, the urine stream in the catheter is straight
Then can not be by channel after in liquid collecting cavity, at this time when urine continues growing, then the pressure in liquid collecting cavity increases, and makes on the branch pipe
Overlay film protrusion.Though however the urological department urethral catheterization device of the structure simplifies operating process, needs that manual operation is coordinated to come in fact
The conducting of existing urine.
It can be seen that design is a kind of automatically controlling urethral catheterization liquid on and off based on amount of urine in patient's bladder

It is uniformly distributed.
In addition, in order to realize that urinary tract flow diverter of the present invention simulates bladder reflex urinary function, the specific pretightning force
H equal to 15cm, 20cm, 30cm or 40cm20 column pressure is multiplied by actuator 6 towards the side of the upper cover 1 and positioned at described close
Area within seal 7.Those skilled in the art can select the compression spring 8 of suitable dimension based on specific above-mentioned parameter request.Wherein
The present invention is based on a large amount of clinical pictures, information and the video information of age, the gender patient different with health degree, statistics is a large amount of
The collection capacity of urine, the bladder pressure of different patients is determined based on the numerical value in patient one day, and it is normal finally to get bladder
Drainage pressure is 15cm~40cmH2O columns.
The embodiment of the present invention also provides a kind of urinary tract drainage device, including catheter, is connected on the catheter
The urinary tract flow diverter stated.
The application method of the above-mentioned urinary tract flow diverter of the present invention：When positioned at original state, sealing ring 7 offsets with protrusion 9, with resistance
It fills between urine inlet 3 and urine outlet 4, since sealing ring 7 is elastic material, offsets in sealing ring 7 and protrusion 9
When, it can realize good sealing function；When about 15cm, 20cm, 30cm or 40cm locate urine at the top of the blanking cover, i.e., equal to wing
Normal excretion pressure 15cm~40cmH of Guang2When O columns, water column pressure is equal with 8 pretightning force of compression spring at this time, with urine after
Continuous discharge, when water column is more than 8 pretightning force of compression spring to the pressure of actuator 6,6 downward compression press spring 8 of actuator, and sealing ring 7
With protrusion 9 be separated, make successively urine via urine inlet 3, the first urethral catheterization passage 10, the second urethral catheterization passage 11 and sleeve 21 with
It is flowed out from urine outlet 4 behind gap between second actuator 62；With the outflow of urine, urine subtracts the pressure of actuator 6
It is small, until less than compression spring 8 pretightning force when, compression spring 8 release and actuator 6 moved upwards under the reaction force of compression spring 8 make it is close
Seal 7 offsets with protrusion 4, to block urine inlet 3 and urine outlet 4.
