In addition, even if the urinary catheter is correctly inserted into the urethra, a urinary catheter blocking condition may occur due to a problem of bladder deformity or the like in some patients. When the above-mentioned catheter tube blocking condition appears, current medical personnel mostly carry out the judgement of whether blocking up the pipe through the bladder flushing mode. However, the effluent after bladder irrigation requires medical staff to collect and extract samples on site and to test the samples in a laboratory, which is time-consuming and laborious, and needless to say, the patient is still in a state of being blocked by the urinary tract during a lengthy test period, and the patient suffers from great pain and seriously affects the actual rehabilitation efficiency of the patient.

Preferably, a sealing cover for opening and sealing the opening is arranged at the opening; the inner side belt surface of the accommodating strip is also provided with an expansion air bag which is used for playing a negative pressure extraction function and sealing a fit gap between a puncture point of a drainage needle at the urinary catheter and a needle body of the drainage needle after expansion, the appearance of the expansion air bag is in a flat saccule attached to the inner side belt surface of the accommodating strip, and the expansion air bag is communicated with the accommodating cavity through an air channel arranged on the accommodating strip; the detection belt also comprises a switch part for opening and closing the air channel; a drainage needle extends through the inflation balloon to communicate with the urinary lumen.
Preferably, the switch part is in a rectangular sheet shape, and a switch hole is formed in the switch part in a penetrating manner; the appearance of the accommodating strip is in a rectangular strip shape, an opening is arranged at the end of one broadside of the accommodating strip, a gap for the switch part to be inserted is concavely arranged at the end of the other broadside of the accommodating strip along the length direction of the accommodating strip, and the gap extends to the air channel along the length direction of the accommodating strip; the switch part has two position states of opening and sealing: when the switch part is in an on state, the switch part is pulled outwards to enable the switch part to conduct linear motion along the length direction of the accommodating strip at the gap until the switch hole at the switch part is overlapped with the air channel, so that the air channel is conducted; when the switch part is in a sealed state, the switch part is pushed inwards to enable the switch part to conduct linear motion along the length direction of the containing strip at the gap until the switch hole at the switch part is completely staggered with the air channel, so that the air channel is closed.
Preferably, the needle tip of the drainage needle is arranged in an outward flanging shape, so that the appearance of the needle tip of the drainage needle is bent hook-shaped or right-angle hook-shaped, and the needle tip of the drainage needle is inclined towards the side where one long side of the containing strip is located.
Preferably, the two ends of the holding strip are adhered to each other by a magic tape so as to be tightly hooped at the outer wall of the urinary catheter; the son face of the magic tape is arranged on the inner side belt face of the end of the drainage needle of the holding strip, and the mother face of the magic tape is arranged on the outer side belt face of the end of the sealing cover of the holding strip.
Preferably, the urine pH value detection method using the medical pH value detection belt is characterized by comprising the following steps of:
1) Before the urethral pH value detection, the holding strip with the built-in PH test paper is close to the wall of the urinary catheter, and the needle point of the drainage needle is hooked on the wall of the urinary catheter until the needle cavity of the drainage needle is communicated with the lumen of the urinary catheter; then, keeping the state that the inner side belt surface of the holding strip is attached to the wall of the urinary catheter so as to clamp the holding strip at the wall of the urinary catheter;
2) When the drainage liquid flowing out exists in the urinary catheter and flows to the position where the containing strip is located along the urinary catheter, the switch part is operated to conduct the air channel, and the drainage liquid can be rapidly sucked into the containing cavity due to the negative pressure environment in the containing cavity, so that the purpose of detecting the pH value of urine on line can be realized through the color change condition of the PH test paper in the containing cavity.
Preferably, in the step 2), when judging whether the urethra is blocked, firstly, the bladder flushing liquid is pumped into the bladder of the patient, and the urinary catheter is waited to start to gradually discharge drainage liquid; when the catheter is not blocked, the drainage liquid sucked into the accommodating cavity is the mixed liquid of urine and bladder flushing liquid, and the PH test paper is correspondingly acid-base color-changing; when the drainage liquid sucked into the accommodating cavity is purely bladder flushing liquid, the PH test paper does not change color, and the catheter is judged to be blocked, so that remedial treatment is required.
The invention has the beneficial effects that:
1) The invention adopts the holding strip with the holding cavity to perform the function of hooping the urinary catheter, and then utilizes the puncture property of the urinary catheter to communicate the holding cavity with the urinary catheter cavity; when urine in the urethra of the human body is discharged along the lumen of the urinary catheter, a part of urine is naturally introduced into the accommodating cavity of the accommodating strip through the drainage needle and then contacts with the PH test paper in the accommodating cavity to change the color. Urine of normal people is slightly acidic under the ordinary diet condition, and the PH value is about 6.5, so that once the PH test paper generates corresponding color change, whether the current urinary catheter is correctly inserted into the urethra can be judged. When the bladder flushing operation is performed to judge whether the urinary catheter is blocked, the invention can be hooped at the urinary catheter, and after the bladder flushing liquid such as normal saline is pumped into the bladder, when the drainage liquid at the bladder flows back along the urinary catheter, the switch part is opened to suck the drainage liquid. If the urinary tract is blocked, the drainage liquid is still normal saline, and the PH test paper in the holding strip cannot be discolored, so that the urinary tract is blocked; if the urinary catheter is not blocked, the drainage liquid is necessarily the mixed liquid of urine and normal saline, weak acid alkalinity still exists, and at the moment, the PH test paper in the holding strip generates corresponding acid alkalinity change. Because the puncture position of the drainage needle at the accommodating strip relative to the urinary catheter can be arbitrarily specified, the drainage needle is positioned as close to the insertion end of the urinary catheter as possible during normal operation, and the aim of draining urine is achieved at the fastest efficiency.
According to the scheme, when the urinary catheter is required to be inserted, the PH test paper is only required to be taken out and put into the accommodating cavity and the accommodating strip is coated on the outer wall of the urinary catheter, and the drainage needle naturally pierces the outer wall of the urinary catheter at the moment so as to be communicated with the lumen of the urinary catheter. The invention has the advantages of simple structure and high convenience in use, can rapidly and efficiently realize the on-line detection of urine and the judgment of whether the urinary catheter is blocked or not, and can even play a role in puncturing the drainage tube in other drainage operations to immediately obtain the effect of the pH value of the current drainage liquid, thereby effectively improving the application range of the invention.
2) Further preferable, the above-mentioned solution is that when the placement of the holding strip is completed and the drainage liquid in the urinary catheter naturally flows out, the drainage liquid in the urinary catheter may not rapidly flow into the holding cavity through the drainage needle due to the difference of air pressure, thereby affecting the detection efficiency. In view of this, the present invention is particularly arranged for an inflatable balloon structure. One side of the expansion air bag is flat and is attached to the inner side belt surface of the containing strip, so that the expansion air bag not only can play a role of a flexible liner; meanwhile, once the switch part is opened to expand the expansion air bag, the expansion air bag can seal the fit gap between the puncture point of the drainage needle at the urinary catheter and the needle body of the drainage needle, so that the problems of cross contamination and the like caused by exudation of drainage liquid such as urine along the fit gap are avoided. On the other hand, the expanding air bag is required to absorb gas when expanding, so that a negative pressure environment can be formed in the accommodating cavity rapidly, further, drainage liquid in the urinary catheter can be led into the accommodating cavity along the drainage needle cavity preferentially, finally, the PH test paper in the accommodating cavity rapidly reacts with the drainage needle cavity, and the detection efficiency of the PH test paper can be greatly improved.
3) The design of the switch part is based on simple operation and thinness as possible, so as to reduce the operation difficulty of the invention and reduce the whole thickness of the invention as much as possible. The preferred switch part of the invention adopts a rectangular sheet shape, and the switch hole is arranged in a penetrating manner on the switch part, and the reciprocating motion of the switch part along the gap is utilized, so that the staggering and overlapping of the switch hole and the air channel at the accommodating strip are realized, and the closing and opening effects of the air channel are further realized.
4) Furthermore, the drainage needle of the invention preferably adopts a bent hook-shaped or right-angle hook-shaped needle head structure, and by adopting the needle head, the drainage needle is realized in a hook-breaking mode when penetrating the catheter wall, thereby avoiding the phenomenon that the catheter is penetrated integrally by careless after the straight needle point penetrates the catheter wall, and improving the reliability of operation. In addition, the needle point of the drainage needle deflects towards one long side of the containing strip, so that the convenience in operation can be ensured, the wall of the urinary catheter is firstly hooked after the containing strip is tilted when the drainage needle is used, the containing strip is aligned and circumferentially surrounds the wall of the urinary catheter and is hooped, and the drainage needle is extremely convenient to use. Because the needle point of the drainage needle is curved, the drainage needle is also arranged in a state that the needle point pierces the inner wall of the urinary catheter due to force application when the subsequent magic tape of the holding strip is stuck.
5) The son face that the magic was pasted is arranged on the inboard area face that holds the drainage needle place end of strip, and the mother face that the magic was pasted is arranged in the outside area face department that holds the closing cap place end of strip to make hold the strip parcel and live the catheter after, switch portion can reveal and be annular holding outside the strip this moment, when guaranteeing to hold the strip relative catheter clamp function, can also be convenient for carry out the corresponding operation of switch portion, multiple purposes.

Detailed Description
For ease of understanding, the specific structure and operation of the invention will be further described herein with reference to the accompanying drawings:
the specific structure of the present invention is shown with reference to fig. 1 to 6, and includes a rectangular strip-shaped receiving bar 10, and an opening is provided at the left end portion of the receiving bar 10 so as to communicate with a receiving chamber 11 inside the receiving bar 10, so as to achieve rapid access and receiving of the PH paper a as shown in fig. 4. To ensure the external tightness of the housing chamber 11, a cover 12 may be provided as shown in fig. 2 to 4 to close the opening after the PH paper a is placed.
On the basis of the above structure, an inflatable balloon 30 is further disposed at the inner belt surface of the right end of the accommodation bar 10, and a drainage needle 20 communicating with the accommodation chamber 11 is disposed in the middle of the inflatable balloon 30. One side of the inflatable air bag 30 is flat and is attached to the inner side belt surface of the accommodating strip 10, so that the inflatable air bag not only can play a role of a flexible liner; meanwhile, once the switch part 40 is opened to expand the expansion air bag 30, the expanded expansion air bag 30 can seal the fit gap between the puncture point of the drainage needle 20 at the urinary catheter b and the needle body of the drainage needle 20, so that the problems of cross contamination and the like caused by exudation of drainage liquid such as urine along the fit gap are avoided. On the other hand, when the inflatable balloon 30 is inflated, the air needs to be sucked, so that a negative pressure environment can be formed in the accommodating cavity 11 quickly, and then the drainage liquid in the urinary catheter b can be guided into the accommodating cavity 11 along the needle cavity of the drainage needle 20 preferentially, and finally the drainage liquid reacts with the PH test paper a in the accommodating cavity 11 quickly. In order to ensure the rapid air suction function and the controllable opening and closing function of the inflatable air bag 30, as shown in fig. 4, the invention is characterized in that the air channel 13 is arranged beside the drainage needle 20 so as to be communicated with the accommodating cavity 11 and the bag cavity of the inflatable air bag 30, and the lamellar switch part 40 is arranged at the air channel 13 so as to realize the controllable opening and closing capability.
After the urethral catheterization is completed, the switch part 40 is operated to conduct the air channel 13, the drainage liquid is sucked into the accommodating cavity 11 due to the negative pressure environment in the accommodating cavity 11, and meanwhile, the puncture point of the wall of the urinary catheter is sealed due to the expansion action of the expansion air bag 30, and at the moment, the acidity and alkalinity of the drainage liquid can be judged through the color change condition of the PH test paper a in the accommodating cavity 11. Of course, the switch 40 may be operated at a timing when the drainage fluid has flowed to the position of the catheter according to the present invention, and the drainage fluid may be sucked at the first time under negative pressure.
There is a benefit in using the above structure in that medical staff is required to sample urine and then transport the sample to the detection room when urine is routinely detected. However, when urine is exposed to the outside for a long time or is left for a long time, bacteria in the urine can decompose urine components to change the pH value of the urine, or carbon dioxide generated by decomposition of bicarbonate in the urine can naturally diffuse into the air to increase the pH value, which can necessarily affect the conventional urine detection result of the current patient. By adopting the invention, the pH value detection of urine in urine routine can be completed directly, and the freshness of the urine is effectively ensured as the urine enters the accommodating cavity 11 of the invention at the first time, and the accuracy and reliability of the detection result are naturally and forcefully ensured.
Furthermore, the present invention does not suggest a conventional straight needle configuration for drainage needle 20, but rather, instead, a right angle needle tip configuration as shown in fig. 5, or further bending the needle tip to form a curved hook-like needle tip configuration, is employed. Thus, on one hand, the puncture property of the drainage needle 20 relative to the wall of the urinary catheter b is not affected by the right-angle needle tip and the hook-shaped needle tip; on the other hand, even if the right-angle needle tip and the hook-shaped needle tip are stressed further after the wall of the urinary catheter b is pierced, the unique structure of the needle tip of the drainage needle 20 can not cause destructive influence on the inner wall of the urinary catheter b at the position opposite to the piercing point, so that the situation that the whole urinary catheter b is pierced due to too strong force when the drainage needle 20 is used for piercing is avoided, and the use reliability of the invention is ensured.
When the urethral pH value is detected, the containing strip 10 with the built-in PH test paper is close to the wall of the urinary catheter b in advance, and the needle point of the drainage needle 20 is hooked on the wall of the urinary catheter b until the cavity of the drainage needle 20 is communicated with the cavity of the urinary catheter b; thereafter, the inner tape surface of the holding strip 10 is held in a state of being adhered to the wall of the urinary catheter b, so that the holding strip 10 is fastened to the wall of the urinary catheter b.
When the drainage liquid flowing out exists in the urinary catheter b and flows to the position of the containing strip along the urinary catheter b, the switch part 40 is operated to conduct the air channel 13, and the drainage liquid can be rapidly sucked into the containing cavity 11 due to the negative pressure environment in the containing cavity 11, so that the purpose of online urine pH value detection can be realized through the color change condition of the PH test paper a in the containing cavity 11.
When judging whether the urethra is blocked, firstly, the bladder flushing liquid is pumped into the bladder of the patient, and the urinary catheter b is waited to start to gradually discharge drainage liquid. At this time, also when the drained drainage liquid exists in the urinary catheter b and flows along the urinary catheter b to the position where the accommodating strip 10 is located, the switch part 40 is operated to conduct the air passage 13, and the drained drainage liquid is rapidly sucked into the accommodating chamber 11 due to the negative pressure environment in the accommodating chamber 11. When the urinary catheter b is not blocked, the drainage liquid sucked into the accommodating cavity 11 is the mixed liquid of urine and bladder flushing liquid, and at the moment, the PH test paper is correspondingly acid-base color-changing; when the drainage fluid sucked into the accommodating cavity 11 is simply bladder flushing fluid, the PH test paper does not change color, and the urinary catheter b is judged to be blocked, so that remedial treatment is required.
