[0037] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0038] See also Figures 1 to 5 In this embodiment, a manometric balloon catheter for neurogenic rectal rehabilitation training includes a catheter body 100, a balloon 200, a first air supply component 300, and a second air supply component 400. The catheter body 100 can be inserted into the rectum of a human body. The first air supply component 300 can supply air to the balloon 200 to perform pressure stimulation on the rectum and monitor the stimulation pressure. The second air supply component 400 can supply air to the protrusion 220 on the balloon 200 to further stimulate the rectum, induce intestinal peristalsis, and establish and exercise reflex defecation.

[0039] The balloon 200 includes a balloon body 210 and an expandable protrusion 220. The balloon body 210 is sleeved on the catheter body 100 and is integrally connected to the catheter body 100. The balloon body 210 can move synchronously with the catheter body 100 and be inserted into the human body. A plurality of protrusions 220 are arranged around the outside of the balloon body 210, and the protrusions 220 can assist the balloon body 210 in stimulating the rectum.

[0040] The first gas supply component 300 is connected to the balloon 210, and can inflate the balloon 210 to expand the balloon 210 relative to the rectum to provide initial stimulation to the support. The first gas supply component 300 can also monitor the pressure of the gas in the balloon 210 to understand the effective pressure threshold of the patient's rectum.

[0041] The second air supply component 400 includes a plurality of air supply pipelines 410. The balloon 210 is equally divided into a plurality of stimulation areas around the central axis of the catheter body 100. Each stimulation area is arranged relative to a specific portion of the inner wall of the rectum. The air supply pipeline 410 is connected to the plurality of protrusions 220 in the stimulation area. The plurality of air supply pipelines 410 supply air to the protrusions 220 in different stimulation areas in turn, so that the protrusions 220 expand relatively, thereby stimulating the rectum in different areas, simulating a circular massage of a specific area of ​​the rectum by human hands, relieving spasms of the internal sphincter and the external sphincter, and at the same time expanding the rectal cavity to induce rectal anal excitatory reflexes.

[0042] In some embodiments, see Figures 1 to 3 The protrusion 220 has an expanded state protruding relative to the capsule 210 and a contracted state concave relative to the balloon 200. In the contracted state, the protrusion 220 forms a concave outside the capsule 210. Lubricants or enema drugs can be pre-smeared in the concave. The concave can protect the drugs from being separated from the capsule 210 at the anus in advance and temporarily store the drugs. When the protrusion 220 changes from the contracted state to the expanded state, the drugs will be squeezed out of the concave and act on a specific area of ​​the rectum.

[0043] In some embodiments, see Figure 3 and Figure 4 The air supply pipeline 410 is arranged in the sac 210. The air supply pipeline 410 includes a first pipe section 411 arranged around the catheter body 100 and a plurality of second pipe sections 412 arranged vertically relative to the first pipe section 411. The second pipe section 412 is connected to the first pipe section 411. The first pipe section 411 is arranged around the catheter body 100 to provide a stable main passage for gas delivery. Gas can be input from the first pipe section 411 to the plurality of second pipe sections 412, and gas is delivered to the plurality of second pipe sections 412 at the same time. The second pipe section 412 is provided with a plurality of openings corresponding to the plurality of protrusions 220. Gas can be delivered relative to the protrusions 220 from the plurality of openings, so that the protrusions 220 are transformed from a contracted state to an expanded state. The air supply system can realize the individual control of the plurality of protrusions 220, so as to accurately stimulate different areas of the rectum and meet the needs of personalized treatment.

[0044] In the specific implementation process, the first pipe section 411 is a first arc tube that is bent around the catheter body 100 and is consistent with the latitude direction of the capsule 210. The second pipe section 412 is a second arc tube that is relatively bent and is consistent with the meridian direction of the capsule 210. The end of the second arc tube is connected to the first arc tube, and the first arc tube can transport gas to the second arc tube. The number of the second arc tubes is generally not less than three and they are arranged equidistantly from each other, so that gas can be supplied to the three groups of protrusions 220.

[0045] The annular first pipe section 411 ensures uniformity of gas distribution, avoiding excessive or insufficient pressure in certain areas due to uneven airflow. The multi-point distribution structure of the second pipe section 412 disperses the airflow to multiple independent protrusions 220, ensuring reasonable distribution of pressure, so that each protrusion 220 expands with the same force, reducing uneven stimulation during treatment.

[0046] The independent connection between each protrusion 220 and the air supply opening enables the system to achieve time-sharing expansion and zoned stimulation by controlling the order and intensity of air supply to different second tube segments 412 .

[0047] It should be noted that an annular inner cavity is provided in the middle of the capsule 210, and the first pipe segment 411 and the second pipe segment 412 are both provided in the annular inner cavity, and the first pipe segment 411 and the second pipe segment 412 are embedded in the solid inner wall of the capsule 210 and are integrally connected with the capsule 210. The air supply pipeline 410 and the capsule 210 are integrated into one, which reduces the exposure of parts and components, helps to reduce the friction or damage risk between the pipeline connection point and the external environment, enhances the overall strength and durability of the equipment, and prolongs the service life.

[0048] In addition, the gas supply pipeline 410 is completely embedded in the solid inner wall of the capsule 210 and placed in the annular inner cavity to form a double-layer protection, which can effectively prevent gas leakage due to pipeline exposure, improve the sealing of the gas circuit and the stability of gas supply, and ensure precise control of the stimulation pressure.

[0049] In some embodiments, see Figure 5 The second gas supply assembly 400 further includes a gas source 420 and a controller 430, and the gas supply pipeline 410 further includes a solenoid valve 413 and a gas delivery pipe 414. The solenoid valve 413 is arranged on the gas delivery pipe 414, and the two ends of the gas delivery pipe 414 are respectively connected to the first pipe section 411 and the gas source 420. The gas from the gas source 420 can be connected to the protrusion 220 through the gas delivery pipe 414, the solenoid valve 413 and the gas supply pipeline 410 in sequence. The setting of the solenoid valve 413 can accurately control the flow of gas according to the instructions of the controller 430, ensuring that the gas in each pipe section can be distributed as needed. By controlling whether the gas enters the first pipe section 411, excessive gas is prevented from entering, ensuring the accuracy of the pressure stimulation.

[0050] The connection between the controller 430 and the multiple solenoid valves 413 enables the system to accurately control the expansion of each stimulation area in a time-sharing manner. By timing the opening and closing of the solenoid valves 413, the time-sharing expansion of the multiple protrusions 220 can be achieved, ensuring that the treatment time and pressure of each stimulation area are independent and accurate.

[0051] The gas source 420 and the solenoid valve 413 work in coordination through an automated system, reducing the complexity of manual operations and improving the efficiency and consistency of treatment.

[0052] In the specific implementation process, the gas source 420 can be a small medical air compressor to provide power for the expansion and contraction of the protrusion 220. The solenoid valve 413 is a two-position four-way solenoid valve 413. One working state of the solenoid valve 413 is that the gas pipe 414 is connected to the first pipe section 411, and the protrusion 220 is in an expanded state. Another working state of the solenoid valve 413 is that the gas pipe 414 is connected to a relatively cut-off pipeline to avoid air pressure leakage. The first pipe section 411 is connected to the outside through the solenoid valve 413, and the gas in the protrusion 220 is released, so that the protrusion 220 shrinks and restores.

[0053] The controller 430 may be a PLC controller 430 or a single chip microcomputer, and the controller 430 may control the opening and closing time and the opening and closing duration of the solenoid valve 413 .

[0054] In some embodiments, see Figure 1 The first air supply component 300 includes an inflation pipeline 310 and an air pressure control unit arranged in the catheter body 100. The two ends of the inflation pipeline 310 are respectively connected to the air pressure control unit and the balloon 210. The addition of the air pressure control unit can accurately adjust the expansion degree of the balloon 210 according to needs, avoiding rectal tissue damage or insufficient stimulation due to excessive expansion.

[0055] The addition of the air pressure control unit can accurately adjust the expansion degree of the balloon 210 according to demand, avoid rectal tissue damage or insufficient stimulation due to excessive expansion, meet personalized treatment needs, and improve the safety and effectiveness of rehabilitation training.

[0056] At the same time, the air pressure control unit can provide a real-time pressure monitoring function to understand the effective pressure threshold of the patient's rectum and anal sphincter in a personalized way. The air pressure control unit can record the pressure data when the balloon 210 is inflated, providing doctors with real-time feedback information during the patient's treatment process, which helps to evaluate the patient's rectal pressure tolerance and provide a scientific basis for subsequent treatment plans.

[0057] In a specific implementation process, the gas control unit may be an electric proportional valve, a digital pressure controller, a medical air pressure pump or a manual air bag pressure gauge.

[0058] When the gas control unit is an electric proportional valve, the two ends of the electric proportional valve are connected to the capsule 210 and the air compressor respectively through pipelines. The gas flow and pressure are accurately adjusted through electronic control signals, and the pressure output range is flexibly controllable.

[0059] When the gas control unit is a digital pressure controller, the two ends of the digital pressure controller are connected to the capsule 210 and the air compressor respectively through pipelines. The digital pressure controller can accurately adjust and monitor the air pressure, support preset pressure values, and automatically control the pressure to reach the set range.

[0060] When the gas control unit is a medical air pressure pump, the medical air pressure pump can provide stable air pressure output and a built-in pressure regulating device, which is suitable for medical environments. The medical air pressure pump also has a built-in pressure monitoring function and can be linked with an external monitoring system.

[0061] When the gas control unit is a manual air bag pressure gauge, the air bag can be manually squeezed to pressurize the bag body, the meter body can be observed to monitor the air pressure and limit the pressure range, and the effective pressure threshold of the anorectal can be tested.

[0062] In some embodiments, see Figure 1 and Figure 2 The interior of the catheter body 100 is hollow and open at both ends to form a hollow cavity. The setting of the hollow cavity allows an endoscope or fiber optic equipment to be placed during the treatment process, and the state of the inner wall of the rectum can be observed through the catheter body 100, which is convenient for diagnosing lesions or evaluating treatment effects.

[0063] The catheter body 100 is relatively transparent, so that the operator can clearly observe the flow of gas and liquid inside the catheter and possible obstructions or contaminants. During the use of the catheter, the expansion state of the balloon 210 and the cleanliness of the internal pipeline can be monitored in real time to ensure safe operation.

[0064] As a further embodiment, the end of the catheter body 100 relatively close to the balloon 210 is relatively rounded to form a relatively smooth annular portion, which can effectively reduce the friction and stimulation on the inner wall of the rectum during the catheter insertion process, reducing pain and discomfort. The smooth annular portion prevents sharp edges from scratching the intestinal tissue, protects the mucosa, and improves patient acceptance.

[0065] At the same time, the rounded edges reduce the risk of damaging the rectal lining during insertion or adjustment of the catheter, which is especially suitable for patients with fragile intestines.

[0066] The smooth structure of the annular part can naturally conform to the physiological curve of the rectum during insertion, reducing resistance and making it easier for the catheter to reach the target position, thereby reducing obstruction during insertion and improving the efficiency and accuracy of medical operations.

[0067] In some embodiments, the end of the catheter body 100 relatively far from the capsule 210 is provided with a mounting hole 110 for mounting a fiber endoscope. The mounting hole 110 increases the expansibility of the catheter body 100. The fiber endoscope can be used in conjunction with other optical devices (such as fluorescence imaging or narrow-band imaging) for a more comprehensive rectal tissue examination. By installing endoscopic devices of different specifications, the application scenarios of the catheter can be expanded, such as drug delivery, cleaning or other minimally invasive operations. The combination of the fiber endoscope and the catheter realizes the simultaneous inspection and treatment, reducing the inconvenience and pain of multiple operations for patients.

[0068] The present invention also provides a training method, which uses a manometry balloon catheter for neurogenic rectal rehabilitation training, and the steps are as follows:

[0069] S1: Catheter insertion, first, cancel the gas supply to the balloon 210 and the protrusion 220, so that the balloon 210 and the protrusion 220 are relatively contracted. Then, fill the protrusion 220 in the contracted state with medicine, and finally, under the direct observation of the fiber endoscope, slowly insert the catheter body 100 into the anus.

[0070] S2: Pressure test: When the balloon 210 contacts the anus, the first air supply component 300 is driven to slightly inflate the balloon 210 to measure the anal sphincter pressure. Then, the balloon 210 is deflated. Next, the catheter body 100 is driven to continue to go deeper into the anus until the balloon 210 reaches the predetermined position of the rectum. Then, the balloon 210 is inflated by the first air supply component 300, and the rectal pressure is measured while slightly stimulating the rectum to understand the effective pressure threshold of the patient.

[0071] S3: Zonal stimulation. At a predetermined position of the rectum, an action area matching the multiple stimulation areas of the capsule 210 is formed on the annular inner wall of the rectum. The action area is divided into action area No. 1, action area No. 2, action area No. 3 and action area No. 4 which are connected in a ring in sequence. Through the precise control of the solenoid valve 413, the rectal wall located in action area No. 1 is firstly acted upon by multiple protrusions 220. The protrusions 220 can be quickly switched between the expansion state and the contraction state to simulate the pressing of the rectal wall by the finger, and the duration is 15s. Then, the action area is switched to action area No. 2, action area No. 3 and action area No. 4 in sequence, forming a cycle of 60s in length. After a rest of 180s, the above process is repeated to relieve the spasm of the internal sphincter and the external sphincter, while expanding the rectal cavity and inducing the rectal anal excitatory reflex.

[0072] It should be noted that during the pressure test step, if fecal impaction is found in the rectum through fiber endoscope observation, an enema tube needs to be inserted from the hollow cavity of the catheter body 100 into the rectum, and an enema is poured into the fecal impaction to soften the fecal impaction. Then, a fecal removal clip is inserted into the rectum through the catheter body 100 to clear the fecal impaction, so that the rectum remains relatively unobstructed.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
