Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary treatment device for constipation and its usage method. Background Technology

[0002] Constipation is a common digestive system disorder, mainly characterized by difficulty in defecation, prolonged constipation, and reduced bowel movement frequency. Constipation is usually related to factors such as intestinal motility disorders, intestinal sensory dysfunction, and insufficient defecation reflexes. The normal defecation process involves the coordinated work of the enteric nervous system, spinal cord, and brain. Rectal pressure receptors sense pressure signals from feces, which are transmitted via nerves to the brain and spinal cord. Combined with voluntary reflexes and conscious control, this ultimately completes the defecation process.

[0003] However, due to various reasons (such as intestinal motility dysfunction, abnormal nerve conduction, etc.), some patients fail to initiate or complete the defecation process normally, leading to constipation symptoms. Traditional methods for treating constipation, such as laxatives, fiber supplements, and physical therapy, can relieve constipation symptoms, but they do not fundamentally address the problem of dysfunction in the defecation reflex. Therefore, developing an adjunctive therapeutic device that can stimulate the rectal wall to activate the defecation reflex has become an important direction in constipation treatment research. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing technologies do not fundamentally solve the problem of defecation reflex disorder, and to provide a constipation auxiliary treatment device and its usage method that can achieve targeted intervention for defecation reflex disorder in constipation patients.

[0005] To achieve the above objectives, the present invention proposes a constipation auxiliary treatment device, comprising an insertion tube, wherein a vibration sleeve is provided at the inner end of the insertion tube, and a vibration motor is provided inside the vibration sleeve; a medium pipeline is connected to the outer end of the insertion tube for inputting or outputting medium into or out of the lumen of the insertion tube; and multiple protrusions are provided on the outer wall of the insertion tube.

[0006] As a further description of the above technical solution: a shape memory alloy frame is provided inside the mounting cavity, the upper end of the shape memory alloy frame is connected to the vibration sleeve, the lower end of the shape memory alloy frame is connected to the insertion tube, and multiple support rods are connected to the shape memory alloy frame.

[0007] As a further description of the above technical solution: a vibration motor is installed on the memory alloy frame, a protective shell is provided on the outside of the vibration motor, a magnetic block is connected to the end of the support rod, and a metal sheet adapted to the magnetic block is provided inside the insertion tube.

[0008] As a further description of the above technical solution: a fixing cavity is provided inside the insertion tube, and multiple fixing frames are provided inside the fixing cavity, with the metal sheet disposed inside the fixing frames.

[0009] As a further description of the above technical solution: the protrusion has an installation groove inside, an electrode plate is installed inside the installation groove, and the electrode plate is connected to the control panel through a wire.

[0010] As a further description of the above technical solution: a pressure sensor is provided inside the bump, the pressure sensor is located on one side of the electrode plate, the pressure sensor is connected to the control panel through a wire, and an alarm is provided on the control panel.

[0011] As a further description of the above technical solution: the vibration sleeve has an installation cavity inside, the vibration motor is installed in the installation cavity, the insertion tube has a transmission groove at its end, and a transmission retaining ring is provided at the connection between the vibration sleeve and the insertion tube.

[0012] As a further description of the above technical solution: a baffle is connected to the bottom of the insertion tube, an adjustment cavity is formed inside the insertion tube, the output end of the medium pipeline is connected to the adjustment cavity, and the adjustment medium pipeline includes a water inlet pipe and / or an air inlet pipe.

[0013] The method of using the constipation aid device includes the following steps: S1, perform a rectal manometry test on the patient to obtain the minimum pressure value P0 that causes the defecation reflex, which is used as the reference threshold of the device; S2, apply water-soluble lubricant to the tip of the insertion tube and slowly insert the tube into the anal canal; S3, introduce liquid or gas through the medium tube until the pressure reaches P0 and the urge to defecate is enhanced; S4, slowly withdraw the insertion tube.

[0014] As a further description of the above technical solution: In step S3, if there is still no urge to defecate after a long time, the electrode plate inside the protrusion on the insertion tube is controlled to work and perform continuous and repeated electrical stimulation.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] This invention utilizes the mechanical pressure generated by the expansion of the insertion tube and its regulating cavity, the local stimulation of the rectal wall by the lateral protrusion, and the low-frequency vibration of the vibration motor in the vibrating sleeve to activate the rectal wall mechanoreceptors and neural conduction pathways in a multimodal synergistic manner, triggering the defecation reflex. This achieves targeted intervention for defecation reflex disorder in constipation patients, making up for the shortcomings of traditional therapies that do not address the neural mechanisms, and providing a comprehensive solution for constipation treatment from physiological reflex activation to mechanical power enhancement.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be noted that the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Please see Figure 1-7 The present invention provides a technical solution: the constipation auxiliary treatment device of the present invention includes an insertion tube 1, a vibration sleeve 2 is provided at the inner end of the insertion tube 1, and a vibration motor 9 is provided inside the vibration sleeve 2; a medium pipeline is connected to the outer end of the insertion tube 1 for inputting or outputting medium into or out of the lumen of the insertion tube 1; a plurality of protrusions 7 are provided on the outer wall of the insertion tube 1, a baffle 3 is connected to the bottom of the insertion tube 1, an adjustment cavity 4 is formed inside the insertion tube 1, the output end of the medium pipeline is connected to the adjustment cavity 4, and the adjustment medium pipeline includes a water inlet pipe 5 and / or an air inlet pipe 6.

[0029] In the technical solution of this invention, water or air can be added to the regulating cavity 4 through the medium pipeline, causing the insertion tube 1 to expand. Multiple protrusions 7 can provide local compression stimulation to the rectal wall. The vibration motor 9 can drive the vibration sleeve 2 and the insertion tube 1 to vibrate, enhancing the stimulation effect. The mechanical pressure generated by the expansion of the insertion tube 1 and its regulating cavity through fluid or air filling, the local stimulation of the rectal wall by the outer protrusions 7, combined with the low-frequency vibration of the vibration motor 9 in the vibration sleeve 2, multimodal synergistic activation of the rectal wall mechanoreceptors and nerve conduction pathways triggers the defecation reflex. At the same time, the baffle 3 ensures the safe positioning of the device, thereby achieving targeted intervention for defecation reflex disorder in constipated patients. This makes up for the shortcomings of traditional therapies that do not address the neural mechanisms, providing a comprehensive solution for constipation treatment from physiological reflex activation to mechanical power enhancement. Compared with traditional methods, this device not only relieves constipation symptoms but also helps to fundamentally restore normal defecation function, providing a more lasting therapeutic effect.

[0030] In specific use, the constipation auxiliary treatment device provided by the present invention has the insertion tube 1 inserted into the rectum through the patient's anus, with the inner end of the insertion tube 1 being the end away from the patient's anus and the outer end of the insertion tube 1 being the end close to the patient's anus.

[0031] Specifically, the vibrating sleeve 2 has an installation cavity 8 inside, the vibrating motor 9 is installed in the installation cavity 8, the insertion tube 1 has a transmission groove 201 at its end, and a transmission retaining ring 202 is provided at the connection between the vibrating sleeve 2 and the insertion tube 1. Through the transmission groove 201 at the end of the insertion tube 1, the vibrating motor 9 is installed in the vibrating sleeve 2, and the vibration generated by the vibrating motor 9 can be transmitted to the side wall of the insertion tube 1 through the transmission retaining ring 202, which enhances the vibration effect of the insertion tube 1, thereby stimulating the rectal wall and enhancing the stimulation effect. At the same time, the setting of the transmission retaining ring 202 makes the installation and disassembly of the vibrating sleeve 2 and the insertion tube 1 more convenient. During the maintenance and repair of the device, the vibrating motor 9 or other components can be replaced or inspected more easily, which improves the maintainability of the device and extends its service life.

[0032] like Figure 2 and Figure 3As shown, a shape memory alloy frame 10 is installed inside the mounting cavity 8. The upper end of the shape memory alloy frame 10 is connected to the vibration sleeve 2, and the lower end is connected to the insertion tube 1. Multiple support rods 11 are connected to the shape memory alloy frame 10. The shape memory alloy material has temperature memory characteristics, which can adjust its shape and hardness according to changes in temperature or external force. The shape memory alloy frame 10 can adjust its shape according to the patient's needs to adapt to different body shapes and treatment requirements, enhancing the adaptability and comfort of the treatment device. The multiple support rods 11 connected to the shape memory alloy frame 10 provide additional structural support. The design of the support rods 11 makes the overall structure more stable, ensuring that the device remains stable during treatment and avoiding fluctuations in treatment effect or discomfort caused by the patient's movements or the instability of the device itself.

[0033] like Figure 3 and Figure 4 As shown, a vibration motor 12 is installed on the shape memory alloy frame 10. A protective shell 13 is provided outside the vibration motor 12. A magnetic block 14 is connected to the end of the support rod 11. A metal sheet 15 adapted to the magnetic block 14 is provided inside the insertion tube 1. A fixing cavity 16 is opened inside the insertion tube 1. Multiple fixing frames 17 are provided inside the fixing cavity 16. The metal sheet 15 is placed inside the fixing frame 17. When the vibration motor 12 is started, the vibration of the vibration motor 12 is transmitted to the shape memory alloy frame 10, and then transmitted to the support rod 11 and the magnetic block 14 through the shape memory alloy frame 10, so that the magnetic block 14 drives the metal sheet 15 to vibrate.

[0034] The shape memory alloy frame 10 is provided with multiple support rods 11 in both the circumferential and transverse directions. Each support rod 11 includes a first rod body 1101 and a second rod body 1102. The first rod body 111 and the second rod body 1102 have different lengths. The different lengths of the first rod body 1101 and the second rod body 1102 make the distances between the multiple magnetic blocks 14 and the metal plates 15 different, so that the vibration amplitude of each metal plate 15 is also different, thereby enhancing the vibration effect.

[0035] like Figure 3 and Figure 5As shown, a mounting groove 18 is provided inside the protrusion 7, and an electrode plate 19 is installed inside the mounting groove 18. The electrode plate 19 is connected to the control panel 20 via wires. Multiple protrusions 7 are distributed on the outside of the insertion tube, and the position of the electrode plate 19 in each protrusion 7 is relatively fixed, which helps to achieve precise stimulation of specific parts of the rectum. The electrode plate 18 and the pressure sensor 21 are located together in the protrusion. When pressure stimulation is achieved by filling the insertion tube with liquid or gas to expand it, electrical stimulation can be activated simultaneously or as needed, working in conjunction with pressure stimulation to form a synergistic effect. Pressure stimulation simulates the pressure of feces on the rectal wall, activating mechanoreceptors; electrical stimulation acts directly on nerve endings, enhancing nerve signal transmission. The combination of the two can more effectively activate the defecation reflex, improving the treatment effect of constipation. The control panel 20 can receive feedback information from the pressure sensor 21 and other components. Based on this feedback, the operator can adjust the electrical stimulation parameters of the electrode plate 19 in real time, making the treatment process more in line with the patient's actual situation and further improving the effectiveness of the treatment.

[0036] The mounting slot provides a relatively stable and safe installation environment for the electrode pads. It prevents physical damage such as impacts and friction during use, ensuring the integrity and performance stability of the electrode pads. Simultaneously, the mounting slot also helps prevent direct corrosion of the electrode pads by bodily fluids, extending their lifespan. Installing the electrode pads within the mounting slot facilitates insulation. Furthermore, the wiring connecting the electrode pads to the control panel provides excellent insulation, reducing the risk of leakage. This is crucial for patient safety, preventing electric shock injuries to the rectal tissue caused by leakage.

[0037] Specifically, the design of the protrusion 7 allows the electrode pad to better conform to the rectal wall. The surface of the rectal wall is not completely flat, and the protrusion 7 can adapt to its irregular shape, allowing for closer and more thorough contact between the electrode pad 19 and the rectal wall. This enables the electrical stimulation to be applied more precisely to the target area, enhancing the stimulation of nerve endings in the rectal wall and improving the activation efficiency of the defecation reflex. Doctors can select the appropriate electrode pad 19 position for electrical stimulation via the control panel 20, based on the patient's specific condition, to provide personalized treatment for constipation with different causes and symptoms.

[0038] like Figure 3 and Figure 5As shown, a pressure sensor 21 is installed inside the protrusion 7. The pressure sensor 21 is located on one side of the electrode plate 19. The pressure sensor 21 is connected to the control panel 20 through a wire. An alarm 22 is installed on the control panel 20. The protrusion 7 has a built-in miniature piezoresistive sensor (accuracy ±0.5kPa) to monitor the rectal wall pressure in real time. It is compared with a preset threshold (determined by rectal pressure measurement) and the inflation volume is automatically adjusted. The control panel 20 integrates a micro MCU (such as STM32) to connect the pressure sensor and the display interface. The control panel 20 has a touch screen to display the real-time pressure, inflation volume, and stimulation mode (pressure / electric stimulation). It supports password lock to prevent accidental operation. If the pressure fluctuation exceeds ±3kPa or inflation fails continuously, the alarm 22 will sound and the machine will stop.

[0039] like Figure 1 and Figure 2 As shown, the insertion tube 1 is made of silicone, and the memory alloy frame 10 is made of nickel-titanium alloy. The insertion tube 1 is an ergonomic spindle shape with a rounded front end (diameter 18-22mm) and a gradually widened rear end to a maximum diameter of 30-35mm. The total length is about 180mm, which facilitates the insertion of the anal cannula and the even distribution of pressure. The insertion tube 1 is made of medical-grade silicone with a matte finish to improve lubrication. The built-in memory alloy frame 10, made of nickel-titanium alloy, supports repeated expansion and contraction without deformation.

[0040] The method of using the constipation aid device includes the following steps: S1. Perform a rectal manometry test on the patient to obtain the minimum pressure value P0 that triggers the defecation reflex, which is used as the reference threshold of the device; S2. Apply water-soluble lubricant to the tip of the insertion tube 1 and slowly insert the insertion tube 1 into the anal canal; S3. Introduce liquid or gas through the medium pipeline until the pressure reaches P0 and the urge to defecate is enhanced; S4. Slowly withdraw the insertion tube 1; Determine the minimum effective pressure threshold P0 for the patient by pressure measurement, input it into the control panel 20, insert the insertion tube 1 after lubrication, conform to the curvature of the rectum, inject warm water / gas to expand the adjustment chamber to P0, simulating fecal filling. If the pressure stimulation is ineffective, activate the electrode 19. After the defecation reflex is triggered, release the pressure and slowly withdraw the device.

[0041] Specifically, the patient first undergoes a rectal manometry test to obtain the minimum pressure value that triggers the defecation reflex (e.g., P0 = 10 kPa), which serves as the baseline threshold for the device. P0 is input into the device interface, and the system automatically sets the stimulation pressure range to P0 ± 2 kPa (which can be adjusted ± 1-3 kPa according to tolerance). In pressure stimulation mode, the pressure is maintained for 30-60 seconds. If no defecation urge is generated, inflation can be repeated 1-2 times at 2-minute intervals (to avoid overstimulation). In electrical stimulation mode (only used when pressure stimulation is ineffective), the pulse frequency (e.g., 10 Hz) is selected, and the intensity is gradually increased from 2 mA to a slight tingling sensation perceptible to the patient (≤8 mA). Each electrical stimulation lasts 15 seconds, repeated at 30-second intervals, and can be used a maximum of 3 times.

[0042] Rectal manometry is an examination method that assesses defecation function and anal sphincter coordination by measuring changes in pressure in the rectum and anus. During the examination, a manometry catheter is inserted into the rectum, and pressure data is recorded by sensors. The entire process takes about 30 minutes. It is non-invasive and safe, and patients must follow the doctor's instructions to complete the procedure.

[0043] If there is still no urge to defecate after a long period of time, the electrode plate 19 inside the protrusion 7 on the insertion tube 1 is controlled to work and perform continuous and repetitive electrical stimulation.

[0044] Before inserting the insertion tube 1 into the anal canal, a lubricating guide sleeve can be fitted onto the insertion tube 1 to reduce insertion friction. A conductive coating (such as a nano silver coating) or conductive fiber can be embedded in the inner wall of the guide sleeve to form a current conduction path.

[0045] Working principle: Water or air can be added to the regulating chamber 4 through the medium pipeline, causing the insertion tube 1 to expand. Multiple protrusions 7 can provide local compression stimulation to the rectal wall. The vibration motor 9 drives the vibration sleeve 2 and the insertion tube 1 to vibrate, enhancing the stimulation effect. The mechanical pressure generated by the expansion of the insertion tube 1 and its regulating chamber by fluid or air, the local stimulation of the rectal wall by the outer protrusions 7, combined with the low-frequency vibration of the vibration motor 9 in the vibration sleeve 2, activates the rectal wall mechanoreceptors and nerve conduction pathways in a multimodal synergistic manner, triggering the defecation reflex. At the same time, the baffle 3 ensures the safe positioning of the device, thereby achieving targeted intervention for defecation reflex disorder in constipated patients. This makes up for the shortcomings of traditional therapies that do not address the neural mechanisms, providing a comprehensive solution for constipation treatment from physiological reflex activation to mechanical power enhancement. Compared with traditional methods, this device not only relieves constipation symptoms but also helps to fundamentally restore normal defecation function, providing a more lasting therapeutic effect.
