Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a laxative device for constipation patients based on endoscopic visualization and airbag assistance and a mobile terminal integrated system. Background Art

[0002] Visualized nasoenteric tube placement technology uses endoscope or image guidance to achieve precise catheter placement for enteral nutrition support, solving problems such as low success rate and patient discomfort of traditional blind insertion. Its core lies in visual operation, and it does not integrate airbag-assisted defecation function. It is mainly aimed at the fields of nutrition delivery and surgical operations, rather than constipation treatment.

[0003] Currently, the visualization nasoenteric tube placement technology still has the following defects:

[0004] (1) Functional limitations: Although visualization of catheter placement is achieved through endoscopy, its original design was for enteral nutrition support. This technology focuses on the visualization of enteral nutrition catheter placement and only solves the problem of catheter positioning. It does not have a dedicated defecation assistance function designed for constipated patients (such as air balloon dilation, real-time data interaction), and does not integrate air balloon dilation, feces fragmentation or assisted excretion functions. Therefore, it cannot be directly used for the defecation needs of constipated patients;

[0005] (2) Operational complexity: It relies on the independent operation of the endoscope equipment, requires an additional display screen and operating table, lacks real-time connection with mobile terminals, cannot be monitored in real time through portable terminals (such as mobile phones), and does not have an integrated data recording function, cannot record operation data (such as intestinal pressure, airbag status, etc.), and is difficult to optimize the treatment plan;

[0006] (3) Potential injury risk: The catheter is only used to deliver nutrient solution, and manual removal of dry and hard feces is still required. Repeated intubation can easily damage the intestinal mucosa, and the operation time is prolonged, and the patient's tolerance is poor;

[0007] (4) Single function: Focusing on anatomical structure repair, it does not integrate non-invasive defecation assistive devices (such as airbags and visualization catheters), and cannot meet the needs of immediate defecation;

[0008] (5) Insufficient safety and efficiency: Traditional catheters rely on blind insertion or single image guidance, which can easily cause intestinal damage. The surgical plan is highly invasive and cannot achieve both non-invasiveness and efficiency.

[0009] (6) Operation dependence and high cost: It needs to be used with an independent endoscope system or X-ray imaging equipment, and the operation requires the support of a professional team. It lacks portability and intelligent interaction (such as mobile phone control), and its applicable scenarios are limited, making it impossible to achieve portability or home scene application.

[0010] Therefore, we proposed a laxative device for constipation patients based on endoscopic visualization and airbag assistance and a mobile terminal integrated system to solve the above problems. Summary of the Invention

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] Example 1: Reference Figures 1-6 As shown: a laxative device for constipation patients based on endoscopic visualization and airbag assistance, comprising a display terminal 1, a connecting line 2, an operating handle 3 and an integrated tube 4, wherein both ends of the operating handle 3 are connected to the connecting line 2 and the integrated tube 4 respectively, and further comprising an insertion tube 6 and an airbag 7, wherein the insertion tube 6 passes through the airbag 7 and is fixedly connected to the airbag 7, a micro camera module 10 and an optical fiber illuminator 11 are built into the front end of the insertion tube 6, and the other end of the insertion tube 6 is fixedly connected to a connecting end 5, and one end of the integrated tube 4 is connected to one end of the connecting end 5. The wall is threadedly connected, the airbag 7 consists of an outer mesh nylon braided layer 71 and an inner antibacterial silicone layer 72. A pressure relief valve 73 and a pressure sensor 74 are provided inside the antibacterial silicone layer 72. A micro air pump 9 is installed inside the operating handle 3. The surface of the micro camera module 10 is coated with a hydrophobic coating 12, and a transparent protective cover 13 is clamped at the front end of the micro camera module 10. The front end of the probe 6 is designed as a conical flexible head. The connecting line 2 is electrically connected to the display terminal 1, and a lithium battery 8 is installed inside the operating handle 3.

[0055] The working principle of this embodiment: the endoscope display terminal 1, the airbag 7 and the integrated tube 4 of the present invention adopt a split module design (the probe tube 6 and the airbag 7 are fixed, and the inner side of one end of the connecting end 5 is threadedly connected to the end of the integrated tube 4. When it is necessary to connect them, just rotate the integrated tube 4 and fix the integrated tube 4 to the inner side of the connecting end 5. A plurality of transmission lines are arranged in the integrated tube 4, which are respectively connected to the pressure sensor 74, the pressure relief valve 73, the optical fiber illuminator 11, and the micro camera module 10. At the same time, an inflation line for inflating the airbag 7 is arranged in the integrated tube 4, which is convenient for the operator to inflate the airbag 7 through the operating handle 3), and supports quick disassembly. Disassembly, disinfection, and component replacement reduce maintenance costs, solve the problem that traditional integrated catheters are difficult to clean and repair, and extend the service life of the device. When using the device, first disinfect the probe tube 6 (using medical-grade silicone tube, the probe tube 6 has an outer diameter of 6 to 8 mm, and the front end is designed as a tapered flexible head to reduce intestinal insertion resistance). The integrated data cable is connected to the mobile phone via the USB interface / Bluetooth to synchronize the endoscope image. The operating handle 3 has a built-in rechargeable lithium battery 8 (battery life ≥ 4 hours), which supports charging while using. The miniaturized design balances power consumption and performance to ensure continuous operation requirements in home or outdoor scenes. At the same time, all parts that contact the intestine have passed ISO 10993 biosafety certification to avoid allergic or toxic reactions. Start the mobile phone APP to complete the device self-test (including the micro camera module 10, airbag 7, and pressure sensor 74);

[0056] After the self-examination is completed without error, the probe tube 6 is slowly inserted into the rectum or colon. The micro camera module 10 at the front end of the probe tube 6 (diameter ≤ 2mm, frame rate 30fps, supports wide-angle imaging, covers the 120° field of view of the front end of the catheter, and realizes 1080P resolution image acquisition to ensure high-definition field of view in narrow intestines. At the same time, the micro camera module 10 adopts anti-fog and anti-fouling design, the surface of the micro camera module 10 is coated with a hydrophobic coating 12, and a detachable transparent protective cover 13 is installed at the front end to support intraoperative flushing and cleaning) can collect intestinal images of constipated patients in real time. This structural design can break through the volume limitation of traditional endoscopes and adapt to probes. The miniaturized front end of the insertion tube 6 avoids increased operational difficulty due to the size of the device, and transmits the data to the display terminal 1 and the mobile phone APP. Under the guidance of the mobile phone image, the patient slowly inserts the insertion tube 6 and the integrated tube 4 into the rectum or colon. The fiber optic illuminator 11 can realize the intestinal lighting function (dual light source LED array: white light wavelength 450nm, red light wavelength 650nm, the light source brightness and color temperature can be dynamically adjusted through the mobile phone APP to avoid overexposure of the intestinal mucosa, solve the problem of blurred imaging of the endoscope in a fecal contaminated environment, and ensure the stability of visualization throughout the process), avoiding intestinal folds and fragile blood vessels through real-time images;

[0057] When the patient finds that the feces has been located through the display terminal 1 or the mobile phone APP, the end of the probe tube 6 is inserted into the feces. At this time, the "low pressure mode" (10-15kPa, used for positioning) is started through the mobile phone APP, and the micro air pump 9 (the micro air pump 9 is integrated into the operating handle 3, the air pressure range is 0-50kPa, and supports precise adjustment by the mobile phone APP) receives the signal and presses the airbag 7 (the airbag 7 is made of latex or silicone, and the airbag 7 is made of a multi-layer composite material, the inner layer is an antibacterial silicone layer 72, and the outer layer is a mesh nylon braided layer 71. After the airbag 7 is inflated, the front end transitions smoothly. The airbag 7 adopts a composite structure. After inflation, an "olive-shaped" airbag 7 with strong axial traction and controllable radial expansion is formed to avoid intestinal wall damage caused by excessive expansion, and the traction is balanced by material and structural design. At this time, the mobile phone APP switches to "high pressure mode" (20-25kPa, used for defecation). The micro air pump 9 continues to inflate the air bag 7 after receiving the signal. At the same time, the patient slowly pulls back the probe tube 6 and the integrated tube 4, and uses the air bag 7 to mechanically pull out the feces until the probe tube 6 and the integrated tube 4 are completely removed. At the same time, the air bag 7 has a built-in pressure sensor 74, specifically a MEMS pressure sensor 74. The internal pressure of the air bag 7 is monitored in real time by the pressure sensor 74, and the monitored pressure value is fed back to the mobile terminal unit 18 in real time. When the limit is exceeded, the hardware pressure sensor 74 (mechanical) and software pressure limit (dynamic adjustment) dual protection are triggered.

[0058] Example 2: Reference Figures 1-6 Shown: A mobile terminal integrated system for a laxative device for constipation patients based on endoscopic visualization and airbag assistance, including:

[0059] The visual positioning unit 16 displays the internal image of the intestine in real time through the endoscope, visually locates the path of the probe tube 6 and the integrated tube 4, and guides the inflation range of the airbag 7. The visual positioning unit 16 includes a camera module 161, a fiber optic lighting module 162, and an endoscope imaging module 163;

[0060] The camera module 161 collects intestinal images of constipation patients in real time through the micro camera module 10;

[0061] The optical fiber lighting module 162 realizes the intestinal lighting function of the constipation patient through the optical fiber lighting device 11;

[0062] The endoscopic imaging module 163 displays the internal image of the intestine in real time through the display terminal 1 based on the image collected by the camera module 161 .

[0063] The mechanical assist unit 17 realizes the dynamic adjustment of the airbag 7 pressure and the defecation assisting function of the airbag 7 through the multi-layer composite airbag 7 structure + dynamic pressure feedback + dual pressure relief mechanism. The mechanical assist unit 17 includes an airbag assist module 171, an inflation module 172, a pressure feedback module 173, a dynamic pressure upper limit module 174 and an exhaust module 175;

[0064] The airbag auxiliary module 171 inflates and expands the intestines of constipated patients through the airbag 7 made of multi-layer composite material, limiting the radial expansion of the airbag 7 after inflation;

[0065] The inflation module 172 controls the micro air pump 9 through the mobile phone APP, and inflates the airbag 7 through the micro air pump 9 integrated in the operating handle 3. The air pressure range is 0-50kPa, so as to realize the pressure regulation of the airbag 7;

[0066] The pressure feedback module 173 monitors the pressure in the airbag 7 in real time through the pressure sensor 74, and feeds back the monitored pressure value to the dynamic pressure upper limit module 174 and the mobile terminal unit 18 in real time;

[0067] The dynamic pressure upper limit module 174 sets the dynamic pressure upper limit through the APP, and intelligently identifies the intestinal stenosis area in combination with the camera image. When the limit is exceeded, the software pressure limit is dynamically adjusted, and the pressure relief signal is automatically transmitted to the exhaust module 175 to automatically limit the inflation pressure;

[0068] When receiving the pressure relief signal from the dynamic pressure upper limit module 174 , the exhaust module 175 exhausts the airbag 7 through the pressure relief valve 73 to achieve automatic pressure relief.

[0069] The mobile terminal unit 18 is connected to the mobile phone APP via a wire. Through low-latency transmission + AI data fusion analysis + one-button intelligent control, it realizes real-time image transmission, airbag 7 pressure adjustment and synchronous recording and storage of operation data, and supports subsequent analysis and optimization. The mobile terminal unit 18 includes a real-time image display module 181, a transmission module 182, an auxiliary function module 183, an airbag intelligent control module 184, a pressure curve display module 185, a data fusion analysis module 186, a data management module 187 and an AI-assisted decision-making module 188;

[0070] The real-time image display module 181 connects the mobile phone APP to the display terminal 1 through a wire, realizing real-time image transmission, airbag 7 pressure adjustment and synchronous recording and storage of operation data, supporting subsequent analysis and optimization, and synchronizing the endoscope image. The operation data includes intestinal pressure and defecation duration;

[0071] The transmission module 182 is connected via USB / Bluetooth to achieve real-time transmission with a picture delay of less than 200ms, meeting the real-time operation requirements;

[0072] The auxiliary function module 183 is used to implement the zoom, screenshot and video storage functions of the mobile phone APP;

[0073] The airbag intelligent control module 184 supports one-touch inflation / deflation function, with preset low-pressure mode for positioning and high-pressure mode for defecation. The pressure value of the low-pressure mode is 10-15kPa, and the pressure value of the high-pressure mode is 20-25kPa.

[0074] The pressure curve display module 185 is used to record the pressure change of the airbag 7 over time and display the pressure change in a curve to assist in judging the intestinal resistance and stool hardness;

[0075] The data fusion analysis module 186 combines the airbag 7 pressure curve of the pressure curve display module 185 and the endoscopic image of the endoscopic imaging module 163 to identify the nature of the stool and optimize the traction strategy through an AI algorithm, and transmits the data to the data management module 187. The optimization of the traction strategy includes objectively recording pressure, image, and duration data to establish a grading treatment standard for constipation, such as mild, moderate, and severe constipation corresponding to different air pressures and traction strategies;

[0076] The data management module 187 is used to automatically generate operation reports and structured diagnosis and treatment reports, including operation duration, number of times the airbag 7 is used, key frames of intestinal images, marking high-risk operation nodes for subsequent optimization plans, and supports PDF export or cloud synchronization;

[0077] The AI-assisted decision-making module 188 is based on the trained AI algorithm and intelligently recommends the pressure parameters of the airbag 7 according to the hardness of the stool. It can also intelligently recommend and warn of high-risk operations. When the pressure of the airbag 7 suddenly rises, the APP will prompt the possibility of intestinal obstruction.

[0078] The power supply unit 19 can provide power to the electrical components in the visual positioning unit 16 and the mechanical auxiliary unit 17 .

[0079] Working principle of this embodiment: The present invention integrates three major functions of endoscopic imaging, airbag 7 mechanical assistance, and mobile terminal control through modular design. First, after the probe tube 6 and the integrated tube 4 are disinfected, the integrated data cable is connected to the mobile phone via the USB interface / Bluetooth. H.265 encoding can be used to compress the image data. The transmission module 182 realizes the function of transmitting images and control signals, synchronizes the endoscope image, and realizes real-time transmission with a picture delay of less than 200ms, ensuring the synchronization of operation and image display, maintaining high-definition image quality under limited bandwidth, and solving the problems of high delay and poor stability of wireless transmission. The mobile phone APP has a real-time image display function, supports zooming, screenshots and video storage, and starts the mobile phone APP to complete the device self-test (including the micro camera module 10, airbag 7, and pressure sensor 74);

[0080] After the self-examination is completed without error, the probe tube 6 is slowly inserted into the rectum or colon. The micro camera module 10 at the front end of the probe tube 6 can collect the intestinal image of the constipated patient in real time and transmit it to the display terminal 1 and the mobile phone APP. Under the guidance of the mobile phone image, the patient slowly inserts the probe tube 6 and the integrated tube 4 into the rectum or colon, and avoids intestinal folds and fragile blood vessels through the real-time image. When the patient finds that the feces has been located through the display terminal 1 or the mobile phone APP, the end of the probe tube 6 is inserted into the feces. At this time, the "low pressure mode" is started through the mobile phone APP. The micro air pump 9 in the inflation module 172 inflates the airbag 7 after receiving the signal. The airbag auxiliary module 171 slightly expands the intestinal cavity and wraps the feces after the airbag 7 is inflated. At this time, it is switched to the "high pressure mode" through the mobile phone APP. The micro air pump 9 continues to inflate the airbag 7 after receiving the signal. At the same time, the patient slowly pulls back the probe tube 6 and the integrated tube 4, and uses the airbag 7 to mechanically pull out the feces until the probe tube 6 and the integrated tube 4 are completely removed;

[0081] At the same time, the pressure feedback module 173 monitors the internal pressure of the airbag 7 in real time through the pressure sensor 74, and feeds back the monitored pressure value to the dynamic pressure upper limit module 174 and the mobile terminal unit 18 in real time. When the limit is exceeded, the dynamic pressure upper limit module 174 sets the dynamic pressure upper limit through the APP, and intelligently identifies the intestinal stenosis area in combination with the camera image. When the limit is exceeded, the software pressure limit is dynamically adjusted, and the pressure relief signal is automatically transmitted to the exhaust module 175 to automatically limit the inflation pressure. When the exhaust module 175 receives the pressure relief signal from the dynamic pressure upper limit module 174, it exhausts the airbag 7 through the pressure relief valve 73 to achieve automatic pressure relief, thereby avoiding the risk of blind inflation of the traditional airbag 7.

[0082] After the operation is completed, the mobile phone APP can display the pressure curve (during the defecation process, the pressure curve display module 185 of the mobile terminal unit 18 records the changes in the airbag 7 pressure over time in real time, and displays the pressure changes in the form of a curve) to assist in judging intestinal resistance and stool hardness. The data management module 187 of the APP can automatically generate an operation report, including operation time, number of times the airbag 7 is used, intestinal image key frames, and supports cloud synchronization. It can automatically generate a diagnosis and treatment report and mark high-risk operation nodes (such as pressure peaks) for subsequent optimization plans; the data fusion analysis module 186 combines the airbag 7 pressure curve of the pressure curve display module 185 and the endoscopic image of the endoscopic imaging module 163, and uses the AI ​​algorithm to identify the nature of the stool and optimize the traction strategy to establish a constipation classification treatment standard; the AI ​​decision-making auxiliary module 188, based on the trained AI algorithm, intelligently recommends the pressure parameters of the airbag 7 according to the hardness of the stool, and can also intelligently recommend and warn high-risk operations. When the pressure of the airbag 7 suddenly rises, the possibility of intestinal obstruction will be prompted on the APP.

[0083] The present invention combines the flexible design of the front end of the probe tube 6 with real-time endoscope image guidance. The endoscope's 1080P high-definition image displays the internal structure of the intestine in real time, helping the operator to avoid fragile blood vessels, intestinal wall folds and narrow areas, and avoid intestinal mucosal abrasions, perforations or bleeding caused by blind insertion of traditional catheters. The risk of blind insertion is avoided through endoscopic visualization. Compared with enema or surgery, this solution replaces traditional instrument extraction with flexible traction of the airbag 7. The flexible traction of the airbag 7 directly acts on the feces, reducing mechanical stimulation to the intestinal wall and reducing postoperative pain by more than 50%. In addition, the airbag 7 wraps the feces after inflation, and the dry or sticky feces are brought out as a whole through axial traction. The clearance rate of a single operation can reach more than 90% (traditional manual extraction is only 60% to 70%), and the average defecation time is shortened. It is especially suitable for patients with intractable constipation.

[0084] The device is suitable for a wide range of people, supports adjustment of the airbag 7 pressure (10-25kPa) and traction speed, can adapt to different stool hardness (such as dry and hard type, sticky type) and patient intestinal sensitivity (such as the elderly, postoperative patients), can be used to treat children's constipation, filling the gap in pediatric non-invasive laxative devices; by replacing dedicated display devices with mobile phones, and integrating the control interface through the mobile phone APP, primary medical staff or family caregivers can complete the treatment without professional endoscopic operation training, and support use in scenarios such as homes, community clinics and even ambulances, breaking through the traditional endoscope's dependence on fixed operating rooms. It can be operated by primary medical institutions or homes, reducing patients' need for hospitalization; in addition, the device's mobile APP can record and intelligently analyze data throughout the entire process. The APP automatically records the operation time, airbag 7 pressure curve, intestinal image key frames and stool characteristics (such as volume, hardness), generates a structured diagnosis and treatment report, supports PDF export or cloud synchronization, and medical staff can quantitatively evaluate the patient's constipation improvement by comparing historical data, providing a basis for adjusting diet, medication or surgical plans.

[0085] The working principle of the present invention is as follows: when the device is used, the integrated tube 4 and the probe tube 6 are first disinfected, the integrated data line is connected to the mobile phone via the USB interface / Bluetooth, the mobile phone APP is started to complete the device self-test (including the micro camera module 10, the air bag 7, and the pressure sensor 74), and the probe tube 6 is slowly inserted into the rectum or colon. The micro camera module 10 can collect the intestinal images of the constipation patient in real time and transmit them to the display terminal 1 and the mobile phone APP. Under the guidance of the mobile phone image, the patient slowly inserts the integrated tube 4, the air bag 7 and the probe tube 6 into the rectum or colon. The optical fiber illuminator 11 can realize the intestinal lighting function and avoid intestinal folds and fragile blood vessels through real-time images. When the patient finds that the feces has been located through the display terminal 1 or the mobile phone APP, the end of the probe tube 6 is inserted into the feces. At this time, through the mobile phone A PP starts the "low pressure mode", and the micro air pump 9 in the inflation module 172 inflates the airbag 7 after receiving the signal. The airbag auxiliary module 171 slightly expands the intestinal cavity and wraps the feces after inflating the airbag 7. At this time, it switches to the "high pressure mode" through the mobile phone APP. The micro air pump 9 continues to inflate the airbag 7 after receiving the signal. At the same time, the patient slowly pulls back the integrated tube 4 and the probe tube 6, and uses the airbag 7 to mechanically pull out the feces until the integrated tube 4 and the probe tube 6 are completely removed; at the same time, the airbag 7 has a built-in pressure sensor 74, and the pressure feedback module 173 monitors the internal pressure of the airbag 7 in real time through the pressure sensor 74, and feeds back the monitored pressure value to the dynamic pressure upper limit module 174 and the mobile terminal unit 18 in real time. When the limit is exceeded, the dual protection of the hardware pressure sensor 74 (mechanical) and the software pressure limit (dynamic adjustment) is triggered;

[0086] After the operation is completed, the mobile phone app can display the pressure curve to assist in determining intestinal resistance and stool hardness. The app's data management module 187 can automatically generate an operation report, including the operation duration, the number of times the airbag 7 is used, and intestinal image key frames. It supports cloud synchronization and can automatically generate a diagnosis and treatment report, marking high-risk operation nodes for subsequent optimization plans. The data fusion analysis module 186 combines the airbag 7 pressure curve from the pressure curve display module 185 with the endoscopic image from the endoscopic imaging module 163 to identify the nature of the stool and optimize the traction strategy through an AI algorithm, thereby establishing a graded treatment standard for constipation. The AI-assisted decision-making module 188, based on the trained AI algorithm, intelligently recommends airbag 7 pressure parameters based on stool hardness and can also intelligently recommend and warn of high-risk operations. When the airbag 7 pressure suddenly rises, the app will prompt the possibility of intestinal obstruction. The present invention uses a flexible design at the front end of the probe tube 6 combined with real-time endoscopic image guidance to help the operator avoid fragile blood vessels, intestinal wall folds and narrow areas, and avoid the risk of blind insertion through endoscopic visualization. This solution replaces traditional instrument extraction with flexible traction by the airbag 7, reducing mechanical stimulation to the intestinal wall.
