[0001] The invention relates to the technical field of medical devices, and in particular to a medical catheter for monitoring an internal urethral sphincter. Background Art

[0002] Stress urinary incontinence refers to involuntary leakage of urine from the urethra when abdominal pressure increases due to sneezing, coughing, laughing or exercise. Urodynamic examination shows involuntary leakage of urine when abdominal pressure increases without detrusor contraction during filling cystometry. The prevalence of this disease in adult women in China is as high as 18.9%, with the peak age of onset being 50-59 years old. A large part of the causes are caused by relaxation of the internal urethral sphincter, or relaxation of the internal sphincter when the nerve is injured and the command transmission pathway has problems.

[0003] Currently, the treatments for internal urethral sphincter relaxation include pelvic floor muscle training (such as Kegel exercises), drug therapy, behavioral therapy, or surgery when necessary. When establishing a treatment plan, if the patient's internal urethral sphincter pressure can be monitored, the patient's specific situation can be further analyzed and symptomatic treatment can be carried out. However, it is currently difficult to achieve real-time monitoring of the internal urethral sphincter, so a catheter for monitoring the internal urethral sphincter is urgently needed. Summary of the invention

[0015] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work are within the scope of protection of the present invention.

Words such as "connect" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0017] At present, the treatment methods for relaxation of the internal urethral sphincter include pelvic floor muscle training (such as Kegel exercises), drug therapy, behavioral therapy or surgical operation when necessary. When establishing a treatment plan, if the pressure of the patient's internal urethral sphincter can be monitored, the patient's specific situation can be further analyzed and symptomatic treatment can be carried out. However, it is currently difficult to achieve real-time monitoring of the internal urethral sphincter. In response to the above technical problems, the present invention provides a medical catheter for monitoring the internal urethral sphincter. With the expansion positioning component, the pressure sensor can be positioned at the position corresponding to the internal urethral sphincter, so as to achieve real-time monitoring of the internal urethral sphincter and provide real-time pressure data of the internal urethral sphincter for medical staff to perform pathological analysis. The technical solution of the present invention is described in detail below in conjunction with specific examples.

[0018] Reference Figure 1 as well as Figure 2 As shown, a medical urinary catheter for monitoring the internal urethral sphincter of the present invention comprises a tube body 1, a first guide tube 2, an expansion positioning component, a monitoring component and an interface integrated seat. The tube body 1 comprises an insertion end 11 and an external end 12, and the external end 12 is used to connect an external device.

[0019] The first drainage pipe 2 is arranged on the pipe body 1 , and the first drainage hole 21 of the first drainage pipe 2 is arranged at the insertion end 11 , and the first drainage port 22 is arranged at the external retention end 12 .

[0020] The expansion positioning assembly includes a first water bag 3, which is sleeved on the outer edge of the tube body 1. The tube body 1 is provided with a first liquid control pipeline 31 connected to the first water bag 3, and the first liquid control pipeline 31 extends to the outer end 12 for control connection by an external liquid supply device. The first water bag 3 is used to be clamped at the bladder opening of the patient to prevent the tube body 1 from leaving the bladder.

[0021] The monitoring component includes a pressure sensor and a second water bag 4. The second water bag 4 is also sleeved on the outer edge of the tube body 1. The tube body 1 is provided with a second liquid control pipeline 41 connected to the second water bag 4. The second liquid control pipeline 41 extends to the outer end 12 for external liquid supply equipment control connection. The pressure sensor is arranged inside the second water bag 4. A wiring groove 8 for connecting the pressure sensor wire is opened inside the tube body. The outer edge of the second water bag 4 is used to correspond to the patient's internal urethral sphincter. Among them, the connecting line of the pressure sensor is also arranged on the tube body 1 and extends to the outer end 12. In addition, regarding the positioning problem of the second water bag 4 and the first water bag 3, the first water bag 3 corresponds to the bladder opening, and the second water bag 4 corresponds to the internal urethral sphincter. In the face of different patients, the distance value between the internal urethral sphincter and the bladder opening will be slightly different. Therefore, in the design and manufacturing stage of the medical urinary catheter, a variety of urinary catheters with different distance values ​​can be designed and manufactured according to the data group for medical staff to use as needed. Medical staff can select urinary catheters with corresponding distance values ​​for care according to the actual situation of the patient.

[0022] The first water bag 3 and the second water bag 4 are both made of rubber. For the second water bag 4, the second water bag 4 is mainly used to monitor the pressure of the internal urethral sphincter. The monitoring principle is as follows: after the second water bag 4 moves to correspond to the internal urethral sphincter, the second water bag 4 is controlled to expand slowly. During the expansion process, the pressure sensor located inside the second water bag 4 will gradually monitor the floating of the hydraulic pressure, and this value is counted as the floating value. When the second water bag 4 expands to contact the external internal urethral sphincter, the internal urethral sphincter will produce resistance to the periphery of the second water bag 4, so the value of the pressure sensor will gradually increase. At this time, the water in the second water bag 4 is slowly released, and the value of the pressure sensor is observed synchronously. When the value drops to a value close to the floating value, the water pump is stopped, and the liquid in the second water bag 4 is closed and maintained. At this time, the second water bag 4 expands to contact the internal urethral sphincter, and the second water bag 4 is adjusted to the monitoring state. During the monitoring process, the contraction activity of the internal urethral sphincter will compress the second water bag 4, and the pressure sensor converts the action into pressure information and displays it to medical staff through electrical equipment.

[0023] The interface integrated seat is arranged at the external reserved end 12, and the interface integrated seat is respectively provided with interfaces for connecting external devices corresponding to the first drainage port 22, the first hydraulic control pipeline 31, the second hydraulic control pipeline 41 and the pressure sensor, specifically the first drainage interface, the first hydraulic control interface, the second hydraulic control interface and the collection interface. The integrated seat as a whole is mainly used for integrating the connection interface for the outside, and its structural setting is not limited, so it will not be elaborated here.

[0024] It should be noted that before use, this medical catheter needs to be connected to external devices first, where the first drainage interface is connected to the urine bag, the first liquid control interface and the second liquid control interface are both connected to the water pump, and the collection interface is connected to the electrical equipment to display the pressure information of the pressure sensor in real time.

[0025] For example, when the urinary catheter is used to monitor the patient's internal urethral sphincter in real time, the connection of the external device is completed first, and then the urinary catheter is inserted into the patient's urethra until the insertion end 11 of the tube body 1 guides the first water bag 3 into the bladder, and then the external water pump is controlled to inject water into the first water bag 3 through the first liquid control interface to cause the first water bag 3 to expand in the bladder. The expanded first water bag 3 can be stuck in the bladder opening, limiting the insertion end 11 of the tube body 1 from leaving the bladder. After the first water bag 3 is positioned at the bladder opening, the position of the second water bag 4 corresponds to the internal urethral sphincter. At this time, the external water pump is controlled to inject the second water bag 4 through the second liquid control interface until the second water bag 4 is also adjusted to the monitoring state, and the overall installation operation of the urinary catheter is completed. During use, the first drainage tube 2 plays a role in normal urine drainage, while the first water bag 3 plays a role in positioning and limiting detachment, and the second water bag 4 plays a monitoring role. During the monitoring process, the contraction of the internal urethral sphincter will compress the second water bag 4, and the pressure sensor converts the action into pressure information and displays it to medical staff through electrical equipment. Through the overall structural coordination setting, real-time monitoring of the internal urethral sphincter is achieved, and real-time pressure data of the internal urethral sphincter is provided for medical staff to perform pathological analysis.

[0026] In one embodiment, it is more preferred that the medical urinary catheter further comprises a second drainage tube 5, the second drainage tube 5 is arranged on the tube body 1, and the second drainage hole 51 of the second drainage tube 5 is arranged at the insertion end 11, and the second drainage port 52 is arranged at the external retention end 12. In addition, a second drainage interface is also correspondingly arranged on the interface integrated seat for connecting external equipment.

[0027] For example, in one usage scenario, the second guide tube 5 and the first guide tube 2 are arranged in coordination to achieve the effect of liquid medicine care and cleaning for the patient's bladder. When medical staff need to perform liquid medicine care and cleaning on the patient's bladder, they connect the second drainage interface to the water pump, and provide liquid medicine to the second guide tube 5 through the second drainage interface. The liquid medicine enters the interior of the bladder through the second drainage hole 51. As the liquid medicine is injected and cleaned, the waste liquid generated during the cleaning process can be discharged from the first drainage hole 21, and the overall single-cycle effect is achieved. When cleaning care is not required, the second drainage interface can be blocked to prevent urine from flowing out of the second guide tube 5. The setting of the second guide tube 5 can further improve the flexibility of use of the present urinary catheter, and medical staff can provide care according to the needs of the patient, which can improve the care efficiency of medical staff.

[0028] In this embodiment, it is more preferable that the second drainage hole 51 is arranged on the outer edge of the insertion end 11, and the first drainage hole 21 and the second drainage hole 51 are offset from each other. During cleaning and care, it is possible to avoid a large amount of liquid medicine entering the bladder from the second drainage hole 51 and then being discharged through the first drainage hole 21, thereby optimizing the single circulation effect of the first drainage hole 21 and the second drainage hole 51.

[0029] In one embodiment, the overall structure of the pipe body 1 is further refined, and the first guide pipe 2 and the second guide pipe 5 are both opened inside the pipe body 1. In addition, the first hydraulic control pipe 31 and the second hydraulic control pipe 41 are both opened inside the pipe body 1.

[0030] Through the setting of this structure, the tube body 1 can set all the pipelines inside the tube body 1, optimize the overall structure of the tube body 1, and the tube body 1 with a smooth outer edge can facilitate the intubation operation for medical staff.

[0031] In this embodiment, it is more preferred that a reinforcing rib 6 is provided in the tube body 1 , and the reinforcing rib 6 is provided along the length direction of the tube body 1 .

[0032] It should be noted that the opening of multiple pipes inside the tube body 1 will weaken the bending strength of the tube body 1 itself, making the tube body 1 softer and inconvenient for medical staff to perform intubation operations. The setting of the reinforcing ribs 6 can compensate for the bending strength of the tube body 1. In this embodiment, the reinforcing ribs 6 are specifically rubber rods.

[0033] In one embodiment, the installation structure of the first water bag 3 is further refined, and a positioning groove 7 for positioning and installing the first water bag 3 is opened on the outer edge of the tube body 1.

[0034] The setting of the positioning groove 7 can improve the stable installation effect of the first water bag 3 and play a role in positioning the first water bag 3. During use, the first water bag 3 is the main force-bearing component. With the coordinated positioning of the positioning groove 7, the overall stability of use can be further optimized.

[0035] In one embodiment, the installation structure of the second water bag 4 is further refined, and the inner wall of the second water bag 4 and the outer edge of the tube body 1 are arranged in an interference fit.

[0036] It should be noted that a mounting hole (not shown in the figure) is provided on the outer edge of the tube body 1 for the end of the second liquid control pipe 41 to extend out. When installing the second water bag 4, the medical staff can fine-tune the position of the second water bag 4 according to the actual situation of the patient, and the interference fit can form resistance to the movement of the second water bag 4. During use, this resistance can play a role in positioning the second water bag 4 itself.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
