Description
Technical field
The present invention relates to a kind of built-in catheter, and in particular to a kind of according to pressure change drainage control in human bladder
Device derived from urine, belongs to technical field of medical instruments.
Background technology
Clinically there are many paraplegia triggered by the cerebrovascular, myelonic angiopathy, hemiplegic patient, and comatose patient, height
Position paralytic patient etc., they are most of with the obstacle in terms of urination, and indwelling catheter turns into the above-mentioned controlled micturition barrier of solution
The conventional means hindered.The urethral catheterization device that traditional indwelling catheter uses is connected by through catheter and the catheter lower end of insertion urethra
The urinal composition connect.Catheter is continual to export intravesical urine, causes that normal bladder can not be formed in bladder
Internal pressure, the detrusor and internal sphincter of urinary bladder of patient are in useless state for a long time, and low pressure urine storage and low pressure can not be utilized to urinate
Control urine principle protect whole urinary tract system, and through catheter is directly led out in vitro inside human bladder, is increased
The infection risk of human bladder, long-term use of through catheter can produce following risk：
1. catheter continuous drainage makes patient's bladder lack expanded state for a long time, easily cause the bladder wall adhesion；
2. catheter continuous drainage makes bladder reduce with ambient pressure gradient, in order to ensure to drain unobstructed usually need outside increase tube wall
Footpath, hardness etc., cause patient's mucous membrane of urethra to be pressurized and ischemia injury occurs；
3. catheter continuous drainage makes the neural sensor of bladder produce adaptive change, it is impossible to it is full simultaneously to perceive urine in bladder
Urinary reflex is completed, the retention of urine occurs；
4. while pleural drainage urine, the bacterium of urethral catheterization pipe outer wall can occur inversely to infect urinary system；
5. catheter is fixed at human bladder's neck using sacculus, prolonged compressing causes patient's bladder neck that ischemic occurs
Property damage；
6. in order to avoid the phenomenon of catheter leakage of urine, the catheter of larger model is often selected, so patient's urethra can be caused to glue
Film is pressurized and ischemia injury occurs, and is urethral trauma damageable zone, it is easier to be pressurized particularly with narrow membranous urethra
Compel.
In order to solve the above technical problems, China Patent Publication No. CN102405033 discloses a kind of urination control device, bag
Component is prevented in the upstream for including Magnetic Control, and component is prevented in downstream and supporting member, the supporting member are deployed simultaneously in bladder
Urination control device can be kept to be in settling position in urethra, component is prevented in the upstream and downstream prevents component and utilizes magnetic
Ball valve, control human body urination are opened or closed in gravitational attraction, and the device is started intravesical pressure during urination by abdominal pressure regulation, made
Human body controls automatic micturition, solves the technical problem that traditional catheter continuous drainage is brought, but the supporting member of the device is held
Continuous compressing bladder neck, easily causes patient's bladder neck that ischemia injury occurs.
China Patent Publication No. CN203694361 discloses a kind of men's built-in automatic control catheter, including positioned at bladder
The catheter bulging card division of neck and positioned at the distal end bulging card division of male prostate tip, the catheter bulging card division card pressure
In in bladder cavity, the distal end bulging card division prevents catheter from slipping into bladder cavity, and both are located at human body for fixing catheter
Inside urethra.The built-in automatic control catheter is additionally provided with the magnetic urine control switch of Magnetic Control, for controlling beating for urethral catheterization path
Push And Release closes, and which solves the technical problem that traditional catheter continuous drainage is brought, but equally has to human bladder's neck
There is the drawbacks of compressing.
