Description
This case is divisional application, the denomination of invention of original application are as follows: a kind of Cesarean esction bladder positioning urethral catheterization device, original application
The applying date are as follows: 2016-12-27, original application application No. is 201611223689.X.
Technical field
It is the present invention relates to the surgical assist tools technical field such as Cesarean esction, in particular to a kind of with bladder positioning function
Urethral catheterization device.
Background technique
The problems such as passing through cesarean section delivery for solution high risk pregnancy, difficult labour, a tire, obstetrics generally use Cesarean esction.Cut open palace
Production is an important operation midwifery method, is that in the progress of labor, can not make fetus natural due to puerpera or fetus
It gives birth to, and is taken by doctor a kind of through abdominal incision uterus taking-up fetus and its appendicular process.But after being cut due to abdomen, largely
Blood exists, and sight is greatly affected, and apart from too close, doctor can only rule of thumb judge bladder and uterus for uterus and bladder
Position still can increase pain to puerpera, doctor increases work difficulty to practicing midwifery there is a situation where accidentally injuring bladder sometimes；
In Cesarean operation, puerpera Chang Yin is anaesthetized and is influenced automatic micturition function, can thus make dilatation of bladder, uterus is in a short time
It can not just shrink quickly, so as to cause puerpera's bleeding profusely in postpartum, keep puerpera on the line, therefore obstetrics are frequently with leading
Urinary catheter solves the above problems, although the problem of being able to solve urethral catheterization, currently used catheter is gasbag-type catheter, urethral catheterization
After bladder is protruded into the front end of pipe, needs to pour air bag liquid or gas, expand air bag, avoid the abjection of catheter, but swollen
Swollen air bag increases the pressure on the inside of bladder again, can not eliminate the internal pressure of bladder well, guarantee the normal contraction in uterus, separately
Outside, cesarean postoperate often needs self retaining catheter for a period of time, but postoperative tube drawing is again often tired with pain, infection, voluntary micturition
