A kind of neurogenic bladder urination alarm
Technical field
The present invention relates to technical field of medical instruments, is a kind of neurogenic bladder urination alarm.
Background technology
Neurogenic bladder is that the back urinates with bladder and/or store the urine dysfunction because a variety of causes such as spinal cord injury, cerebrovascular accident, diabetes etc. suffer damage the normal micturition reflex arc of body serve as a class clinical syndrome that mainly shows, very common clinically.Because the neural arc of urinating infringement makes the patient can't perception to what of intravesical urine amount, therefore can only or stimulate bladder to urinate by urethral catheterization periodically.This mechanically, periodically emptying bladder method has a lot of shortcomings, also causes severe complications sometimes.As the blanking time of urinating is too short, and number of micturitions is too much, then occur easily urinary system infection, sacral nerve stimulation export license too much, complication such as sacral nerves infringement; Long as if the blanking time of urinating, number of micturitions is very few, stress incontinence can occur on the one hand, can ureter occur because of intravesical pressure is too high on the other hand and backflow, thereby urinary tract, serious appearance uremia is gone up in infringement.Certainly, urine also causes urinary tract infection easily at the intravesical overstand.The patient reaches the number of times of minimizing urethral catheterization and the generation of urinary incontinence in addition, often takes strict water restriction amount to reduce the urine amount; But very few urinary tract infection and the lithangiuria of occurring easily again of urine amount forms vicious cycle.The neurogenic bladder patient often feels more painful because of dysuria, and quality of life is low.Therefore, how to monitor the variation of intravesical urine amount in real time and this information is offered the patient, thereby the purpose that reaches in good time emptying bladder just seems of crucial importance.Although this problem has been carried out years of researches both at home and abroad, do not see the report that is successfully applied to clinical relevant apparatus so far.
Summary of the invention
The purpose of this invention is to provide a kind of Micturition Alent Device that is applicable to the neurogenic bladder patient, make the patient can understand the variation of intravesical urine amount in real time, and, the patient provides information for urinating in good time, thereby can reduce the incidence rate of the caused various complication of timing urination, improve patient's quality of life.
Neurogenic bladder urination alarm of the present invention is made up of permanent magnet and alarm two parts.The good silica gel thin film of permanent magnet outsourcing one deck histocompatibility is so that pass through silica gel thin film edge sutured on wall of urinary bladder.It is box-like that alarm is, and is in series by lead by alarm switch, buzzer, power supply and on and off switch.Alarm switch is installed in the box, is made up of circular scale, pointer, center pivot and collateral branch's axle; Center pivot vertically passes the central point on the circular scale and links to each other with an end of lead at the back side of graduated disc; Collateral branch's axle is positioned at a side of center pivot, vertically passes circular scale and links to each other with the other end of lead at the back side of graduated disc; There is an aperture in the central authorities of pointer, are fixed in by this aperture on the center pivot in graduated disc front.The positive combination of graduated disc, pointer and center pivot is just as the compass of compass, is the degree of filling of bladder but the scale on the graduated disc represents.Pointer can rotate around center pivot under the effect of Magnet, is stopped when pointer rotates to collateral branch's shaft position and connects circuit, and buzzer sends the sound and reports to the police.If in advance collateral branch's axle is located at the scale position that the pointed bladder need be urinated, sends warning so and just mean and to have urinated.Utilize this device, in advance permanent magnet is fixed on the anterior wall of urinary bladder of sagittal plain during use, turn on the power switch again, alarm is fixed in stomach wall median line down, make the sagittal plane position of graduated disc plane corresponding to bladder.With the increase of urine amount, the position of permanent magnet is moved on dilatation of bladder, and the pointer of alarm moves with permanent magnet and rotates around center pivot, when the urine amount reaches preset value, permanent magnet rotates to the collateral branch axle pointer and contacts, and current loop is connected and reported to the police, and expression should have been urinated.When urinating, the position of permanent magnet dwindles with bladder and moves down, and pointer breaks away from collateral branch's axle and moves down gradually, and current loop disconnects and stops to report to the police.The fixed position of permanent magnet and alarm is to determine according to the urodynamics test result before the art and the filling of bladder in the art or emptying testing result.The corresponding relation that how much becomes of the scale value on the graduated disc and intravesical urine amount.According to this corresponding relation, the scale value shown from pointer just can correspondingly estimate intravesical urine amount.
Neurogenic bladder urination alarm of the present invention is simple in structure, with low cost, easy to use, can send the signal of urinating in good time, can alleviate medical personnel's workload, can prevent the too much or very few disadvantage of bringing of number of micturitions again.
