Description
Technical field
The present invention relates to medical instruments field, be specifically related to o urethral catheterization device, especially a kind of pressure detecting automatic urethral catheterization device.
Background technology
Current Clinical practice catheter is divided into two kinds: interim (once) catheter and indwelling catheter, and takes as the leading factor with indwelling catheter.Current indwelling catheter has two kinds of modes: continue urethral catheterization and non-continuous urethral catheterization.Lasting urethral catheterization makes intravesical urine produce at any time and flows out everywhere after referring to and inserting catheter; Non-continuous urethral catheterization refers to that folder closes catheter at ordinary times, urinating (as patient's numbness, then taking the mode of timing urination), being similar to intermittent urethral catheterization when there being urine meaning, and main purpose is protection bladder function.
Intermittent urethral catheterization refers to the catheter with being applicable to, according to filling of bladder situation, every the emptying way once of urethral catheterization in 3-4 hour.Divide the intermittent urethral catheterization of aseptic and spatter property interrupted catheterization two kinds.Aseptic intermittent catheterization is operated by medical worker in hospital, be used for needing short-term to carry out intermittent urethral catheterization with empty bladder, or/and promote the patient that bladder function recovers, as the temporary urine retention or not exclusively emptying caused by nerve, obstructive or postanesthetic various reasons, or the spinal shock phase that spinal cord injury is early stage, or for needing intermittent urethral catheterization patient early stage for a long time, with the intermittent urethral catheterization scheme helping patient to set up individuation.And self-intermittent cleaning urethral catheterization is used for the patient that needs to accept intermittent urethral catheterization for a long time, under the guidance of doctor, patient is oneself operation outside hospital, or has assisted urethral catheterization by family members.
Interrupted catheterization essence makes bladder periodic dilation and emptying by urethral catheterization, maintains bladder approximate physiological conditions, promote the recovery of bladder function, re-training reflex bladder; Its key implemented is urethral catheterization opportunity---emptying when filling of bladder.Traditional method is by formulating drinking-water plan, and that infers bladder fills into machine, timing urination, traditional method needs medical personnel or household's timing urination, cannot realize automatic urinating, to needing the patient carrying out interrupted catheterization for a long time, the method is too loaded down with trivial details, and safe not.
A kind of structural representation for clinical abdominal pressure monitoring system, comprise catheter, pressure transducer, and processor, wherein the top of catheter is for being retained in the bladder of patient, the bottom of catheter is connected with urinal, catheter sidewall is also connected with the capillary tube of one and catheter conducting, the end of capillary tube is connected with pressure transducer, realizes detecting intravesical pressure by pressure transducer.In use, pressure transducer can detect intravesical pressure in real time and force value be sent to processor, the force value real-time judge that processor inputs according to pressure transducer, when intravesical pressure reaches default bladder safe pressure, the electromagnetic valve controlled on evacuating catheter is opened, is urinated; When intravesical pressure is decreased to predetermined minimum, Controlling solenoid valve is closed, and stops urinating; By Real-time Collection bladder pressure, and obtain abdominal pressure according to the corresponding relation of bladder pressure and abdominal pressure, thus achieve monitoring abdominal pressure while Real-Time Monitoring bladder pressure.Above-mentioned monitoring system Problems existing in Clinical practice is, although connection catheter and sensor have employed a capillary tube, contaminant sensor is flowed into avoid urine as far as possible, but, in order to realize the transmission of pressure, capillary tube for being connected with pressure transducer is directly communicated with evacuating catheter 22, when expanding with heat and contract with cold of gas in pipe, or the ambient pressure to cause due to the concussion produced in use procedure increases, or urine pressure is when increasing and cause that in capillary tube, gas is compressed, still there is urine and entered the chance of capillary tube (urine reflux back) and possibility by suck-back, and once urine by capillary flow to pressure transducer, sensing sensitivity will be caused to decline even malfunctioning, not only directly affect the accuracy of the bladder pressure recorded, also for patient brings potential safety hazard, in addition, the urine of backflow can pollute pressure transducer, easy initiation cross infection.The patent of invention of 06 month Granted publication on the 17th in 2015---o urethral catheterization device and abdominal pressure monitoring system (CN103055361B) are on the basis of above-mentioned o urethral catheterization device, buffer air bag is had additional in the rear end of capillary tube, when the gas in catheter is because expanding with heat and contract with cold, or cause ambient pressure to increase owing to shaking, or urine pressure increases when causing the gas in capillary tube to be compressed, gas in buffer air bag then can enter capillary tube as a supplement in time, therefore, the urine avoided in catheter is occurred by the phenomenon that suck-back enters (i.e. urine reflux back) in capillary tube, but the change in the impression external world that the setting of buffer air bag can not be so sensitive, or the phenomenon of urine reflux back can be there is, simultaneously, if when there is gas leakage in buffer air bag, the phenomenon such as pressure sensitive also can be caused malfunctioning.
In order to more effective effectively prevent urine reflux back to pressure transducer initiation pressure faulty sensor, ensure that pressure transducer detects the accuracy of the bladder pressure obtained, also prevent pressure transducer by urine pollution, avoid sensor reuse and cause cross infection, the phenomenons such as the pressure that also avoiding leaks gas simultaneously produces is malfunctioning, the present invention stops urine to enter pressure transducer by hydrophobic membrane, effectively prevent above-mentioned phenomenon.
