Description
Technical field
This utility model relates to medical instruments field, is 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 ways: continue urethral catheterization and non-continuous urethral catheterization.Lasting urethral catheterization makes intravesical urine produce at any time to flow out everywhere after referring to insertion catheter；Non-continuous urethral catheterization refers to that folder closes catheter at ordinary times, urinate when there being urine meaning (such as patient's numbness, then take the mode of timing urination), is similar to intermittent urethral catheterization, and main purpose is protection bladder function.
Intermittent urethral catheterization refers to the catheter being suitable for, and according to filling of bladder situation, empties way once every urethral catheterization in 3-4 hour.Divide aseptic intermittence urethral catheterization and spatter property interrupted catheterization two kinds.Aseptic intermittent catheterization is to be operated by medical worker in hospital, it is used for needing short-term to carry out intermittent urethral catheterization with empty bladder, or/and promote the patient of bladder functional rehabilitation, such as the temporary urine retention caused by nerve, obstructive or postanesthetic various reasons or emptying not exclusively, or the spinal shock phase of spinal cord injury early stage, or need intermittent urethral catheterization patient early stage for long-term, to help patient to set up the intermittent urethral catheterization scheme of individuation.And oneself's intermittent cleaning urethral catheterization is used for needing the long-term patient accepting intermittent urethral catheterization, under the guidance of doctor, patient is oneself operation outside hospital, or has been assisted urethral catheterization by family members.
Interrupted catheterization essence is to be made bladder periodic dilation and emptying by urethral catheterization, maintains bladder approximate physiological conditions, promotes the recovery of bladder function, re-training reflex bladder；Its enforcement it is crucial that urethral catheterization empties when filling of bladder opportunity.Traditional method is that what speculate bladder fills into machine, timing urination by formulating drinking-water plan, traditional method needs medical personnel or household's timing urination, it is impossible to realize automatic urinating, to needing to carry out for a long time the patient of interrupted catheterization, the method is excessively loaded down with trivial details, and safe not.
A kind of structural representation for clinical abdominal pressure monitoring system, including 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 to urinal, being also associated with the capillary tube of one and catheter conducting on catheter sidewall, the end of capillary tube is connected with pressure transducer, it is achieved detect intravesical pressure by pressure transducer.In use, pressure transducer can detect intravesical pressure in real time and force value is sent to processor, the force value real-time judge that processor inputs according to pressure transducer, when intravesical pressure reaches the bladder safe pressure preset, controls the electromagnetic valve on evacuating catheter and opens, urinates；When intravesical pressure is decreased to predetermined minimum, controls closed electromagnetic valve, stop urinating；By Real-time Collection bladder pressure, and the corresponding relation according to bladder pressure Yu abdominal pressure obtains abdominal pressure, it is achieved thereby that monitor abdominal pressure while monitoring bladder pressure in real time.nullAbove-mentioned monitoring system there is problems of in Clinical practice，Connection catheter and a sensor capillary tube despite the use of，To avoid urine to flow into contaminant sensor as far as possible，But，In order to realize the transmission of pressure，Capillary tube for being connected with pressure transducer is directly to connect with evacuating catheter 22，In managing, gas expands with heat and contract with cold、Or the ambient pressure that the concussion owing to producing in use procedure causes increases、Or urine pressure is when increasing and cause that in capillary tube, gas is compressed，Still there is urine and entered chance and the possibility of capillary tube (urine reflux back) by suck-back，And once urine is by capillary flow to pressure transducer，May result in sensing sensitivity and decline even malfunctioning，Not only directly affect the accuracy of the bladder pressure recorded，Also potential safety hazard is brought for patient，Additionally，The urine of backflow can pollute pressure transducer，Easily cause cross infection.The utility model patent o urethral catheterization device of 06 month 17 days Granted publications in 2015 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 owing to concussion causes ambient pressure to increase, or urine pressure increases when causing the gas in capillary tube to be compressed, gas in buffer air bag then can timely enter capillary tube as a supplement, therefore, avoid the urine in catheter and entered the phenomenon generation of (i.e. urine reflux back) in capillary tube by suck-back, but the change that the impression that the setting of buffer air bag can not be so sensitive is extraneous, or the phenomenon of urine reflux back can be there is, simultaneously, if there is gas leakage in buffer air bag, also result in the phenomenons such as pressure sensitive is 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 to reuse and cause cross infection, the phenomenon such as simultaneously also avoid pressure that gas leakage produces malfunctioning, this utility model stops urine to enter pressure transducer by hydrophobic membrane, effectively prevent above-mentioned phenomenon.
