Description
Technical field
The invention belongs to clinical treatment auxiliary device, relate to a kind of catheter, be specifically related to a kind of catheter of monitoring bladder function.
Background technology
The traumatic paralysis that spinal cord injury causes is one of the most serious wound, and the SCI sickness rate of developed country and China is up to 2.83-4.5/10 ten thousand, and residual, dead rate is high.And the incidence rate of the spinal cord injury causing due to operation reason at present also improves year by year, be the key subjects that current neurosurgery and orthopaedics educational circles urgently capture.According to documents and materials, most of diseases of spinal cord, as tumor of spinal cord, cervical spondylosis, spina bifida, tethered cord syndrome and spinal arteriovenous malformations or hemangioma etc. all need operative treatment, to obtaining good curative effect.Yet, owing to lacking corresponding monitoring system in art, particularly means and the measure of omnidistance monitoring bladder function, while causing patient to perform the operation, cannot accurately judge whether art district damages normal nerve, or cause spinal cord injury, and then bring out many complication, excise untotally, cause surgical effect not good.
At present, it is that urinary incontinence, hydronephrosis and the chronic renal failure that neurogenic bladder causes not only has a strong impact on the quality of life of paralytic patient that operation causes the dysuria after spinal cord injury, and is to cause first dead reason.Medical circle has adopted some ways, as: indwelling catheter, interruption urethral catheterization, functional electric stimulation, bladder training method and Drug therapy etc., but these measures are all the remedial measures after damage generation, effect is general, almost cannot recover the function of injured nerve, thoroughly solve the complication such as dysuria.So the means of omnidistance monitoring bladder function just become unique hope that early warning operation causes nerve injury in art.
Due to urethral stricture, and insert catheter, do not had space to place monitoring wire, also cannot monitor the signals direct operations such as neural discharge.Someone additive wire, on catheter, can obtain some signals, but the method (it is outer that wire is placed in catheter) often causes injury of urethra, hemorrhage, to patient, brings many troubles and misery.Meanwhile, the method (wire be placed in catheter in) loose contact, can not effectively collect the signal of predictive value, cannot guided operation.
Therefore, if can research and develop a kind of simple and feasible, effect really, low price, the new-type catheter of monitoring bladder function particularly organically blending with catheter, is that this area medical personnel are desired.
Summary of the invention
The defect or the deficiency that for above-mentioned prior art, exist, the object of the invention is to, and provides a kind of catheter of monitoring bladder function, the complication such as bladder disorders that cause patient's nerve injury to bring for early warning operation on spinal cord.
In order to realize above-mentioned task, the present invention takes following technical solution:
A catheter of monitoring bladder function, is characterized in that, comprises an inflatable rubber tube of hollow, and this rubber tube is divided into inflation end and urethral catheterization side, it is characterized in that:
Described inflation end is provided with inflation inlet and urinal connector;

The shield effectiveness of conductive rubber is as follows:
1. >=200kHz magnetic field: 50dB ~ 70dB;
2. 100MHz electric field: 80dB～120dB;
3. 500MHz electric field: 80dB～130dB;
4. 2GHz plane wave: 60dB～130dB
5. 10GHz plane wave: 50dB～120dB.
This conductive rubber advantage is: shield effectiveness is excellent; Cost is medium; Corrosion resistance is excellent.Collection that can be sensitive and accept electroneurographic signal.
Described seal wire is made by aluminium wire.Conduction electroneurographic signal that can be sensitive.
Catheter of monitoring bladder function of the present invention, for complication such as control postoperative vesical dysfunction etc., alleviates medical personnel's workload, and it is all significant that particularly early warning patient reduces unnecessary operation secondary damage etc.The literature search of doing through applicant, yet there are no similar similar installation.
