Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation nursing, and in particular to a manometry balloon catheter for neurogenic rectal rehabilitation training and a training method. Background Art

[0002] Neurogenic bowel disease refers to damage to the nerves involved in defecation, which disrupts the connection between the defecation center and higher centers, leading to a lack of gastrocolic reflexes and slowed intestinal motility, ultimately leading to defecation disorders, primarily constipation and, less commonly, fecal incontinence. Conservative treatment for neurogenic bowel disease primarily includes nutritional management, increased abdominal pressure, digital rectal examination, anal stretching, artificial defecation extraction, and enema.

[0003] Anal stretching involves inserting a finger into the anus after assessing the anal sphincter, slowly and continuously stretching the rectal wall toward the anus to relieve spasms in the internal and external sphincters, while simultaneously expanding the rectal cavity and inducing anorectal excitatory reflexes. This method carries the risk of cross-infection and lacks assessment of stretching intensity and effectiveness. Summary of the Invention

[0020] S2: Pressure test: After the balloon reaches the predetermined position of the rectum, the first air supply component is used to supply air to the balloon to promote the expansion of the balloon relative to the rectum, thereby initially stimulating the rectum while monitoring the inflation pressure to understand the patient's effective pressure threshold;

[0021] S3: Zoned stimulation: the protrusions located in different stimulation areas are inflated in turn for a period of time to stimulate the annular inner wall of the predetermined part of the rectum.

[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, and 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 assembly 300, and a second air supply assembly 400. The catheter body 100 can be inserted into the human rectum. The first air supply assembly 300 can supply air to the balloon 200 to provide pressure stimulation to the rectum and monitor the stimulation pressure. The second air supply assembly 400 can supply air to the protrusion 220 on the balloon 200 to further stimulate the rectum, induce intestinal peristalsis, and establish and train reflex defecation.

[0039] The balloon 200 includes a body 210 and expandable protrusions 220. The body 210 is sheathed over the catheter body 100 and integrally connected thereto. The body 210 can move synchronously with the catheter body 100 during insertion into the human body. Multiple protrusions 220 surround the body 210 and assist in stimulating the rectum.

[0040] The first air supply assembly 300 is connected to the bladder 210 and can inflate the bladder 210 to expand it relative to the rectum, providing initial stimulation. The first air supply assembly 300 can also monitor the pressure of the gas in the bladder 210 to determine the effective pressure threshold of the patient's rectum.

[0041] The second air supply component 400 includes multiple air supply pipes 410. The balloon 210 is equally divided into multiple stimulation areas around the central axis of the catheter body 100. Each stimulation area is set relative to a specific part of the inner wall of the rectum. The air supply pipe 410 is connected to the multiple protrusions 220 in the stimulation area. The multiple air supply pipes 410 supply air to the protrusions 220 in different stimulation areas in turn, so that the protrusions 220 expand relatively, stimulate the rectum in different areas, and imitate the circular massage of specific areas of the rectum by human hands, relieve the spasm of the internal sphincter and the external sphincter, and at the same time expand the rectal cavity to induce the rectal anal excitatory reflex.

[0042] In some embodiments, see Figures 1 to 3 The protrusion 220 has an expanded state, protruding relative to the balloon body 210, and a contracted state, concave relative to the balloon 200. In the contracted state, the protrusion 220 forms a depression outside the balloon body 210. Lubricant or a suppository can be pre-applied into the depression to prevent the medication from escaping from the balloon body 210 at the anus, temporarily storing the medication. When the protrusion 220 transitions from the contracted state to the expanded state, the medication is squeezed out of the depression and acts on a specific area of ​​the rectum.

[0043] In some embodiments, see Figure 3 and Figure 4 The air supply conduit 410 is disposed within the sac 210 and includes a first tube segment 411 disposed around the catheter body 100 and multiple second tube segments 412 disposed perpendicularly relative to the first tube segment 411. The second tube segments 412 are connected to the first tube segment 411. The first tube segment 411 is disposed around the catheter body 100, providing a stable main pathway for gas delivery. Gas can be input from the first tube segment 411 to the multiple second tube segments 412, and gas can be delivered to the multiple second tube segments 412 simultaneously. The second tube segment 412 is provided with multiple openings that correspond one-to-one with the multiple protrusions 220. Gas can be delivered from the multiple openings to the protrusions 220, causing the protrusions 220 to transition from a contracted state to an expanded state. The air supply system enables individual control of the multiple protrusions 220, thereby precisely stimulating different areas of the rectum and meeting the needs of personalized treatment.

[0044] In a specific implementation, the first tube segment 411 is a first arc tube that curves around the catheter body 100 and aligns with the latitudinal direction of the bladder 210. The second tube segment 412 is a second arc tube that curves in a corresponding direction and aligns with the longitudinal direction of the bladder 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 second arc tubes is generally no less than three and they are arranged equidistantly from each other to supply gas to the three groups of protrusions 220.

[0045] The annular first tube section 411 ensures uniform gas distribution, preventing uneven airflow from causing excessive or insufficient pressure in certain areas. The multi-point distribution structure of the second tube section 412 disperses the airflow to multiple independent protrusions 220, ensuring a reasonable distribution of pressure. This ensures that each protrusion 220 expands with uniform force, reducing uneven stimulation during treatment.

[0046] The independent connection of each protrusion 220 to 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 defined in the center of the bladder body 210, within which both the first and second tube segments 411, 412 are disposed. The first and second tube segments 411, 412 are embedded in the solid inner wall of the bladder body 210 and integrally connected thereto. The air supply line 410 and the bladder body 210 are integrated into one unit, minimizing the exposure of components and reducing the risk of friction or damage between the connection points and the external environment. This enhances the overall strength and durability of the device, extending its service life.

[0048] In addition, the air supply line 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 of protection, which can effectively prevent gas leakage due to exposure of the line, improve the sealing of the air circuit and the stability of the air supply, and ensure precise control of the stimulation pressure.

[0049] In some embodiments, see Figure 5 The second gas supply assembly 400 also includes a gas source 420 and a controller 430. The gas supply line 410 also includes a solenoid valve 413 and a gas pipe 414. The solenoid valve 413 is disposed on the gas pipe 414. The two ends of the gas pipe 414 are respectively connected to the first pipe section 411 and the gas source 420. Gas from the gas source 420 can be sequentially connected to the protrusion 220 through the gas pipe 414, the solenoid valve 413, and the gas supply line 410. The configuration of the solenoid valve 413 can precisely control the flow of gas according to the instructions of the controller 430, ensuring that the gas in each pipe section is distributed as needed. By controlling whether the gas enters the first pipe section 411, excessive gas entry is avoided, ensuring the accuracy of the pressure stimulation.

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

[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 a specific implementation, the air source 420 can be a small medical air compressor, which provides power for the expansion and contraction of the protrusion 220. The solenoid valve 413 is a two-position, four-way solenoid valve 413. In one operating state, the air supply pipe 414 is connected to the first pipe section 411, and the protrusion 220 is in an expanded state. In another operating state, the air supply pipe 414 is connected to a relatively closed pipeline to prevent air pressure leakage. The first pipe section 411 is connected to the outside world through the solenoid valve 413, releasing the air in the protrusion 220 and causing the protrusion 220 to contract and restore.

[0053] The controller 430 may be a PLC controller 430 or a single chip microcomputer. 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 bladder 210 according to needs, 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] The air pressure control unit also provides real-time pressure monitoring, enabling personalized understanding of the effective pressure thresholds of the patient's rectum and anal sphincter. The air pressure control unit records pressure data during balloon 210 inflation, providing physicians with real-time feedback during treatment, helping to assess the patient's rectal pressure tolerance and providing a scientific basis for subsequent treatment plans.

[0057] In a specific implementation process, the gas control unit can 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 pipes. 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 pump, it provides stable air pressure output and a built-in pressure regulator, making it suitable for medical environments. The medical air pump also has a built-in pressure monitoring function that can be linked to an external monitoring system.

[0061] When the gas control unit is a manual airbag pressure gauge, the airbag can be manually squeezed to pressurize the bag body, the gauge body can be observed to monitor the air pressure and limit the pressure range, and the effective pressure threshold of the anorectal area 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 the placement of an endoscope or fiber optic equipment during the treatment process, and the state of the rectal inner wall can be observed through the catheter body 100, which is convenient for diagnosing lesions or evaluating treatment effects.

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

[0064] As a further embodiment, the end of the catheter body 100 closest to the balloon 210 is relatively rounded, forming a relatively smooth annular portion. This rounded shape effectively reduces friction and irritation on the rectal wall during catheter insertion, alleviating pain and discomfort. The smooth annular portion prevents sharp edges from scratching 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 portion 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 location. This reduces obstruction during insertion and improves 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 scalability of the catheter body 100, and 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 for drug delivery, cleaning or other minimally invasive operations. The combination of the fiber endoscope and the catheter enables simultaneous examination and treatment, reducing the inconvenience and pain of multiple operations for patients.

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

[0069] S1: Catheter insertion. First, the air supply to the balloon 210 and protrusion 220 is removed, causing the balloon 210 and protrusion 220 to contract relative to each other. Then, the contracted protrusion 220 is filled with medication. Finally, under direct observation through the fiberoptic endoscope, the catheter body 100 is slowly inserted into the anus.

[0070] S2: Pressure test: When the balloon 210 contacts the anus, the first air supply assembly 300 is activated to slightly inflate the balloon 210 and measure anal sphincter pressure. The balloon 210 is then deflated. Next, the catheter body 100 is driven deeper into the anus until the balloon 210 reaches the predetermined position in the rectum. The first air supply assembly 300 then inflates the balloon 210, gently stimulating the rectum while measuring rectal pressure to determine the patient's effective pressure threshold.

[0071] S3: Zonal stimulation: At a predetermined location on the rectum, an action zone is formed on the annular inner wall of the rectum, matching the multiple stimulation zones of the capsule 210. The action zones are divided into action zones 1, 2, 3, and 4, which are connected in a circular pattern. Through precise control of the solenoid valve 413, the rectal wall in action zone 1 is first acted upon by the multiple protrusions 220. The protrusions 220 can rapidly switch between expanded and contracted states, simulating finger pressure on the rectal wall for 15 seconds. The action zone then switches sequentially to action zones 2, 3, and 4, forming a 60-second cycle. After a 180-second rest, the above process is repeated, relieving spasms in the internal and external sphincters while simultaneously expanding the rectal cavity and inducing the rectoanal excitatory reflex.

[0072] It is important to note that during the pressure test, if fecal impaction is detected in the rectum through fiber endoscopy, an enema tube is inserted through the hollow cavity of the catheter body 100 into the rectum, and an enema is injected into the fecal impaction to soften it. A fecal removal clamp is then inserted into the rectum through the catheter body 100 to clear the fecal impaction and maintain a relatively unobstructed rectum.

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