Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent enema system and method for promoting intestinal rehabilitation in special populations. Background Technology

[0002] In the medical field, enemas are widely used as an important means of intestinal cleansing, constipation relief, and postoperative bowel function recovery, particularly for special groups such as those with chronic constipation, patients after enterostomy, and patients after anal and rectal surgery. However, existing enema techniques have many limitations and cannot meet the precise and safe needs of these special groups.

[0003] Traditional enemas often use a direct current irrigation method, where water enters the intestines in a straight line, only affecting the rectum and proximal descending colon, failing to effectively reach the sigmoid colon, transverse colon, and ascending colon. This method not only has poor irrigation and therapeutic effects, but the uncontrolled water flow can easily cause excessive stimulation or damage to the intestinal wall. Furthermore, it is difficult to effectively stimulate intestinal peristalsis through water flow, resulting in a weak auxiliary effect on intestinal function recovery, especially for patients with chronic constipation, as it fails to fundamentally improve intestinal motility.

[0004] Furthermore, most existing equipment can only control the delivery of enema fluid in a simple way, lacking real-time monitoring of water temperature, water flow rate, and intestinal pressure. It also does not integrate monitoring functions for vital signs such as patient heart rate and pulse, making it impossible to identify risks such as failure to inject fluid, excessive intestinal pressure, and abnormal patient vital signs in a timely manner. Moreover, it lacks an automatic emergency cut-off and pressure relief mechanism, which can easily lead to safety accidents. In addition, it does not use equipment and methods for vortex enema, only considering the cleansing of the intestines without considering the restoration of intestinal health.

[0005] Meanwhile, during the enema process, the backflow of intestinal contents may lead to problems such as infection and equipment contamination. However, the existing equipment has a simple anti-backflow structure design, poor sealing performance, and a high risk of backflow.

[0006] To address the aforementioned issues, this invention proposes an intelligent enema system and method. Through vortex-type water flow design and real-time monitoring by multiple sensors, it achieves precise, safe, and adaptive intestinal rehabilitation treatment, meeting the personalized needs of special populations. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent enema system and method for promoting intestinal rehabilitation in special populations, so as to solve the problems existing in the prior art.

[0008] To achieve the above objectives, this invention provides an intelligent enema system and method for promoting intestinal rehabilitation in special populations, including an enema fluid storage module, a delivery pipeline, a lifting and rotating assembly, a control unit, and an enema execution assembly. It further includes: an electromagnetic flow detection module connected in series in the delivery pipeline for real-time detection of the enema fluid flow rate; an anti-backflow assembly located at the end of the delivery pipeline and connected to the enema execution assembly, comprising a one-way sealing valve seat and an elastic sealing element, which opens under positive fluid pressure and closes under reverse fluid pressure to prevent backflow of intestinal contents; and an intestinal environment sensing module, including a contact pressure sensor and a temperature sensor, located at the front end of the enema execution assembly. The control unit is electrically connected to the electromagnetic flow detection module, the anti-backflow assembly, and the intestinal environment sensing module, and the control unit has a built-in flow-pressure matching algorithm that can dynamically adjust the enema fluid delivery rate according to intestinal environment parameters.

[0009] Furthermore, the electromagnetic flow detection module includes a housing, an excitation coil, electrodes, and a signal processing board; the excitation coil is a toroidal coil; the signal processing board is fixed to the outside of the housing by bolts; and the housing is provided with a self-cleaning interface that communicates with the delivery pipeline.

[0010] Furthermore, the anti-backflow assembly includes a valve body, a one-way sealing valve seat, an elastic sealing element, a pressure feedback submodule, and a spring; the one-way sealing valve seat is an annular structure, fixed inside the valve body, and has an annular sealing groove on its surface; the elastic sealing element is a hemispherical structure, with a diameter adapted to the inner diameter of the one-way sealing valve seat, and the bottom of the sealing element is connected to the spring via a connecting rod; the pressure feedback submodule includes a pressure sensor and a signal transmission line, which is connected to the control unit via the signal transmission line.

[0011] Furthermore, it also includes an eddy current generating module, which is disposed inside the conveying pipeline and includes a sleeve, a spiral blade and a fixed shaft; the two ends of the sleeve are detachably connected to the conveying pipeline by clamps; the fixed shaft is arranged along the central axis of the sleeve and the two ends are fixed to the inner wall of the sleeve by brackets.

[0012] Furthermore, the intestinal environment sensing module includes a mounting base, a contact pressure sensor, a temperature sensor, and a humidity sensing unit; the mounting base is a cylindrical structure, with one end threadedly connected to the front end of the enema execution component; there are two contact pressure sensors, symmetrically embedded in the side wall of the mounting base; the temperature sensor is encapsulated in a stainless steel protective tube and is located at the center of the front end of the mounting base along the axis of the mounting base; the humidity sensing unit includes a porous ceramic probe, a pressure sensor, and a sealed cavity.

[0013] Furthermore, the control unit includes an identity recognition module and an interface module, wherein the identity recognition module can read the information from the wristband worn by the patient.

[0014] This invention also discloses an intelligent enema method for promoting intestinal rehabilitation in special populations. This intelligent enema method for promoting intestinal rehabilitation in special populations is applied to any of the enema systems described above. The method includes the following steps: S1: Collecting basic parameters of intestinal pressure, temperature, and humidity through an intestinal environment sensing module; S2: The control unit calls matching database parameters and sets the initial delivery rate through an electromagnetic flow detection module; S3: Real-time monitoring of enema fluid flow rate and intestinal pressure changes; automatically adjusting the delivery rate when pressure fluctuations exceed a threshold; S4: After the enema is completed, activating the anti-backflow component to lock the pipeline and complete the system's self-cleaning process.

[0015] Furthermore, in step S3, a PID closed-loop control algorithm is used, with an adjustment response time of no more than 0.5s and a flow rate adjustment accuracy of ±0.1mL / s.

[0016] Furthermore, when the enema fluid volume reaches 1 / 3, 1 / 2, or 2 / 3 of the total volume, the vortex generation module in the control unit can be selectively activated to convert the enema fluid into a micron-level vortex form. Through vortex perfusion, a gentle stimulation of the intestines is achieved, promoting intestinal peristalsis, accelerating intestinal cleansing, and promoting the recovery of intestinal health.

[0017] Furthermore, it also includes abnormal handling steps: when the anti-backflow component triggers a reverse pressure alarm, the transmission power is immediately cut off and the pipeline depressurization is initiated, while the abnormal parameters are recorded to the system log.

[0018] This invention provides an intelligent enema system and method for promoting intestinal rehabilitation in special populations, which has the following beneficial effects: 1. By using a vortex generation module, the limitations of traditional direct current perfusion are overcome, transforming the enema fluid into a vortex form. The vortex-type water flow rhythmically washes the intestinal wall in a rotating manner, which can gently stimulate the intestinal wall to produce physiological peristalsis, enhance the intestinal motility, and fundamentally improve chronic constipation. It can also deliver the rinsing fluid to the distal intestine, such as the sigmoid colon, transverse colon, and ascending colon, greatly expanding the scope of rinsing and treatment, improving intestinal cleanliness and drug absorption. It is especially suitable for patients who require precise intestinal care after colostomy, anal and rectal surgery, and effectively promotes the recovery of intestinal function.

[0019] 2. The anti-backflow component adopts a combination structure of one-way sealing valve seat and hemispherical elastic sealing element. It can achieve efficient anti-backflow by opening with positive pressure and closing with reverse pressure, eliminating infection and equipment contamination caused by the backflow of intestinal contents. At the same time, it prolongs the retention time of the infusion fluid in the intestine and promotes the enema effect.

[0020] 3. The electromagnetic flow detection module has a self-cleaning interface on its outer shell. After the enema is completed, the system automatically starts the pipeline locking and self-cleaning process to remove residual liquid and dirt in the pipeline, prevent bacterial growth, and reduce the risk of cross-infection. It is especially suitable for long-term use by special needs people with low immunity.

[0021] 4. The identification module of the control unit can read the patient's wristband information and automatically retrieve the patient's historical usage parameters such as tolerable flow rate, suitable water temperature, and intestinal environment baseline value, so as to achieve personalized adaptation for each person without the need for re-adjustment each time, making the operation convenient.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] This embodiment provides an intelligent enema system and method for promoting intestinal rehabilitation in special populations, including an enema fluid storage module 01, a delivery pipeline 03, a lifting and rotating assembly 04, a control unit, and an enema execution assembly 06. It also includes: an electromagnetic flow detection module 02, connected in series in the delivery pipeline 03, for real-time detection of the enema fluid flow rate; an anti-backflow assembly 07, located at the end of the delivery pipeline 03 and connected to the enema execution assembly 06, comprising a one-way sealing valve seat and an elastic sealing element 15, which opens under positive fluid pressure and closes under negative fluid pressure to prevent backflow of intestinal contents; and an intestinal environment sensing module 08, including a contact pressure sensor and a temperature sensor, located at the front end of the enema execution assembly 06. The control unit is electrically connected to the electromagnetic flow detection module 02, the anti-backflow assembly 07, and the intestinal environment sensing module 08, and the control unit has a built-in flow-pressure matching algorithm that can dynamically adjust the enema fluid delivery rate according to intestinal environment parameters.

[0029] Specifically, the enema fluid storage module 01 is connected to the delivery pipeline 03 via a quick-connect coupling, and the interface is sealed with a medical-grade sealing ring to eliminate the risk of leakage. An electromagnetic flow detection module 02 is connected in series in the middle of the delivery pipeline 03. The module's housing is made of antibacterial material and is fixed to the lifting and rotating assembly 04 with pipe clamps. The lifting and rotating assembly 04 allows for 0-180° rotation on the crossbar and 0-1.5m height adjustment to ensure compatibility with the user.

[0030] At one end of the delivery pipeline 03 near the enema execution component 06, an anti-backflow component 07 is connected. The front end of the enema execution component 06 is made of round-headed silicone to avoid damaging the intestinal mucosa. The intestinal environment sensing module 08 is fixed to the front end of the enema execution component 06 by threads to ensure that the sensor probe is in full contact with the intestinal wall. The eddy current generating module 05 is fixed at both ends in the middle section of the delivery pipeline 03, specifically between the electromagnetic flow detection module 02 and the anti-backflow component 07. At the same time, the sleeve 09 matches the inner diameter of the delivery pipeline 03 to avoid liquid stagnation.

[0031] It is easy to understand that this system uses the control unit as the central hub, the delivery pipeline 03 as the channel, and the sensing module as the core, and the assembly of each component must meet the requirements of sterility, stability and ease of operation of medical equipment.

[0032] Specifically, the electromagnetic flow detection module 02 includes a housing, an excitation coil, electrodes, and a signal processing board; the excitation coil is a toroidal coil; the signal processing board is fixed to the outside of the housing by bolts; and the housing is provided with a self-cleaning interface that communicates with the delivery pipeline 03.

[0033] Therefore, the electromagnetic flow detection module 02 is connected in series in the delivery pipeline 03 to detect the flow rate of the enema fluid in real time. A self-cleaning interface is located on the side of the casing, with a built-in one-way valve. After the enema is completed, the control unit controls the cleaning water pump to inject 37℃ physiological saline into the interface at a flow rate of 5 mL / s for 30 seconds, flushing away any residual enema fluid and dirt from the inner wall of the pipeline. After cleaning, wastewater is discharged through the interface, completing the self-cleaning process. This allows the system to automatically flush the pipeline after the enema is completed, preventing residue buildup. The signal processing board converts the flow signal collected by the electrodes into a digital signal, which is transmitted to the control unit via a communication protocol. The detection accuracy can reach ±0.1 mL / s, meeting the requirements for dynamic adjustment.

[0034] Specifically, the anti-backflow assembly 07 includes a valve body 16, a one-way sealing valve seat, an elastic sealing element 15, a pressure feedback submodule, and a spring 13; the one-way sealing valve seat is an annular structure, fixed inside the valve body 16, and has an annular sealing groove 17 on its surface; the elastic sealing element 15 is a hemispherical structure, with a diameter adapted to the inner diameter of the one-way sealing valve seat, and the bottom of the sealing element is connected to the spring 13 through a connecting rod 14; the pressure feedback submodule includes a pressure sensor and a signal transmission line, which is connected to the control unit through the signal transmission line.

[0035] See Figure 3 It is known that the anti-backflow component 07 is located at the end of the delivery pipeline 03 and connected to the enema execution component 06. It includes a valve body 16 and a one-way sealing valve seat, located within the valve body 16. The valve body 16 has an annular sealing groove 17, an elastic sealing element 15, a spring 13, a connecting rod 14, and a pressure feedback submodule. The elastic sealing element 15 has a hemispherical structure, adapted to the inner diameter of the one-way sealing valve seat, and its bottom is connected to the spring 13 via the connecting rod 14. Under positive fluid pressure, the sealing element opens; under reverse pressure, it closes, effectively preventing the backflow of intestinal contents. Specifically, it also includes a vortex generating module 05, located within the delivery pipeline 03, including a sleeve 09, a spiral blade 10, and a fixed shaft 12. The sleeve 09 is detachably connected to the delivery pipeline 03 at both ends via clamps. The fixed shaft 12 is arranged along the central axis of the sleeve 09, and its two ends are fixed to the inner wall of the sleeve 09 via brackets 11.

[0036] refer to Figure 2 It can be seen that the internal structure of the eddy current generating module 05 is assembled with a sleeve 09 made of transparent medical PVC material, and a fixed shaft 12 made of stainless steel, which is arranged along the central axis of the sleeve 09. Both ends are fixed to the inner wall of the sleeve 09 by three evenly distributed brackets 11 to ensure the stability of the fixed shaft 12. The spiral blade 10 is made of polypropylene material and rotates around the fixed shaft 12 three times. When the liquid flows through the blade, a stable eddy current is formed, which breaks the enema fluid into eddy current droplets, thereby achieving orderly flushing of the intestinal wall.

[0037] Specifically, the intestinal environment sensing module 08 includes a mounting base, a contact pressure sensor, a temperature sensor, and a humidity sensing unit; the mounting base is a cylindrical structure, with one end threadedly connected to the front end of the enema execution component 06; there are two contact pressure sensors, symmetrically embedded in the side wall of the mounting base; the temperature sensor is encapsulated in a stainless steel protective tube and is located at the center of the front end of the mounting base along the axis of the mounting base; the humidity sensing unit includes a porous ceramic probe, a pressure sensor, and a sealed cavity.

[0038] Therefore, the intestinal environment sensing module 08 is located at the front end of the enema execution component 06, and includes a cylindrical mounting base, two symmetrically embedded contact pressure sensors, a temperature sensor encapsulated in a stainless steel protective tube, and a humidity sensing unit. It can collect intestinal pressure, temperature, and humidity parameters in real time and transmit them to the control unit.

[0039] Specifically, the control unit includes an identity recognition module and an interface module, wherein the identity recognition module can read information from the wristband worn by the patient.

[0040] Therefore, the control unit is the core of this system, integrating an identity recognition module and an interface module. It can read the information from the patient's wristband and retrieve personalized historical parameters. The control unit has a built-in flow-pressure matching algorithm that can dynamically adjust the enema fluid delivery rate based on data fed back from the intestinal environment sensing module 08.

[0041] In one preferred embodiment, the lifting and rotating component 04 is used to adjust the insertion angle and depth of the enema execution component 06 to adapt to the anatomical differences of different patients and improve the comfort and effectiveness of operation.

[0042] The present invention also provides a method for implementing an intelligent enema system for promoting intestinal rehabilitation in special populations, comprising the following steps: S1: Collect basic parameters of intestinal pressure, temperature and humidity through the intestinal environment sensing module 08; S2: The control unit calls the matching database parameters and sets the initial delivery rate through the electromagnetic flow detection module 02; S3: Real-time monitoring of enema fluid flow rate and intestinal pressure changes; automatically adjusts delivery rate when pressure fluctuations exceed the threshold. S4: After the enema is completed, the anti-backflow component 07 is activated to lock the pipeline, completing the system's self-cleaning process. Specifically, step S3 uses a PID closed-loop control algorithm, with an adjustment response time not exceeding 0.5s and a flow rate adjustment accuracy of ±0.1mL / s.

[0043] When the enema fluid volume reaches 1 / 3, 1 / 2, or 2 / 3 of the total volume, the eddy current generator module 05 in the control unit can be selectively activated to convert the enema fluid into a micron-level eddy current. The system also includes an abnormality handling procedure: when the anti-backflow component 07 triggers a reverse pressure alarm, the delivery power is immediately cut off and the pipeline depressurization is initiated, while simultaneously recording the abnormal parameters to the system log.

[0044] refer to Figure 4It is known that the specific procedure of this method is as follows: the patient wears a special wristband, the enema fluid is injected into the enema fluid storage module 01, the temperature of the enema fluid is set, the system self-test is started, and the communication of each module is checked to see if it is normal; the medical staff assists the patient to take a left lateral decubitus position with both knees bent, expose the anal area, sterilize the front end of the enema execution component 06, and apply medical lubricant to reduce the frictional resistance during insertion.

[0045] The enema execution component 06 is slowly inserted into the patient's anus. During insertion, the control unit displays data collected in real time by the intestinal environment sensing module 08, including initial intestinal pressure and intestinal temperature. If the collected parameters exceed the normal range, the control unit immediately issues an audible and visual alarm, stops the insertion operation, and re-collects data after troubleshooting.

[0046] If normal, the control unit reads the patient's wristband information, calls the patient's historical matching parameters in the database, and combines the current pressure value collected in step S1. The electromagnetic flow monitoring module 02 sets the initial delivery rate, and the infusion pump starts to deliver the enema fluid according to the set rate.

[0047] During delivery, the electromagnetic flow detection module 02 transmits flow data to the control unit once per second, and the intestinal environment sensing module 08 transmits pressure data once per second. The control unit displays the flow and pressure curves on the screen in real time for easy observation by medical staff. When the pressure fluctuation exceeds the threshold, the control unit activates the control algorithm to reduce the delivery rate from 2 mL / s to 1.7 mL / s within 0.5 seconds, causing the pressure to drop back to 1.1 kPa and maintaining stable intestinal pressure. If the control unit sends a start signal to the vortex generation module 05, the spiral blades 10 rotate under the propulsion of the liquid, converting the enema fluid into a micron-level vortex. Through vortex perfusion, a gentle stimulation of the intestine is achieved, promoting intestinal peristalsis and accelerating intestinal cleansing and the recovery of intestinal health.

[0048] When the enema fluid delivery volume reaches the set value or the patient actively requests to stop, the control unit sends an enema end signal, the infusion pump stops working, and the elastic sealing component 15 of the anti-backflow component 07 is reset under the elastic force of the spring 13, tightly fitting with the one-way sealing valve seat, locking the pipeline, and preventing intestinal contents from flowing back into the delivery pipeline 03.

[0049] Simultaneously, the control unit controls the opening of the self-cleaning interface of the electromagnetic flow detection module 02, and starts the cleaning water pump to inject 37℃ physiological saline into the delivery pipeline 03 at a flow rate of 5mL / s for 30s. After rinsing the inner wall of the pipeline, the wastewater is discharged through the drain outlet of the anti-backflow component 07. After the self-cleaning is completed, the system automatically records the usage data to the database for subsequent traceability.

[0050] The above method is based on the above system and is applicable to special populations such as those with chronic constipation, those who have undergone enterostomy, and those who have undergone anal and rectal surgery. Clinical operation should be performed by medical staff or trained family members.

[0051] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
