[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive of other embodiments.

[0021] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0022] See also Figures 1 to 10 As shown, the present invention provides an irrigation device for pediatric gastroenterology, comprising a fixing portion 1, an irrigation portion 2 fixedly disposed inside the fixing portion 1, and the irrigation portion 2 is connected to a storage portion 3 via a pipeline; The fixing part 1 can be opened to remove the irrigation part 2 as a whole for maintenance: The irrigation part 2 can perform extraction and injection operations through the internal channel; The irrigation part 2 includes a fixed tube 201, an infusion pole 202, a drainage pole 203, a fixed ring 204, a fixed cover 205 and a camera 206. Two fixed tubes 201 are provided, and both fixed tubes 201 are fixedly connected to the interior of the fixed part 1. The lower end of the infusion pole 202 is fixedly connected to the upper end of one of the fixed tubes 201. The drainage pole 203 is assembled on the outer edge of the infusion pole 202. The fixed ring 204 is rotatably connected to the lower end of the infusion pole 202, and the inner side of the fixed ring 204 is threadedly connected to the lower end of the drainage pole 203. The fixed cover 205 is threadedly connected to the upper end of the infusion pole 202. The camera 206 is fixedly connected to the inside of the fixed cover 205. The camera 206 adopts waterproof packaging and anti-fog coating.

[0023] Specifically, during the lavage operation, the fixed cover 205 of the lavage part 2 is inserted into the patient's digestive tract, and the internal conditions of the patient's digestive tract are observed through the camera 206. The camera 206 is embedded in the front end of the fixed cover 205 and uses a wide-angle lens and low-light enhancement technology to ensure that clear images can be captured even in complex cavities. According to the internal condition of the patient's digestive tract, the irrigation liquid in the storage part 3 is pumped into the infusion rod 202 through the fixed part 1. The irrigation liquid in the infusion rod 202 is transported to the fixed cover 205 and discharged to the affected area for flushing, thus completing the infusion of the liquid. After a predetermined amount of liquid medicine is poured into the patient, the reservoir 3 is controlled to draw liquid from the drain rod 203, creating a negative pressure inside the drain rod 203. The negative pressure inside the drain rod 203 is used to draw liquid medicine from the fixed cover 205, allowing the liquid medicine to be drawn out of the patient's body through the drain rod 203 and then discharged into the reservoir 3 for storage. This completes the process of extracting liquid medicine. After the irrigation operation is completed and the irrigation part 2 is to be maintained, it is only necessary to separate the fixed cover 205 from the infusion rod 202, and then rotate the fixed ring 204 to separate the fixed ring 204 from the drainage rod 203. Then the drainage rod 203 can be pulled out along the infusion rod 202, so that the drainage rod 203 and the infusion rod 202 are separated. At the same time, the infusion rod 202 can also be separated from the fixed tube 201, thereby facilitating the maintenance and cleaning of the drainage rod 203 and the infusion rod 202, and realizing convenient cleaning and maintenance of the equipment.

[0024] See also Figure 10 As shown, a limiting groove is provided on the outer edge of the fixing tube 201, and the limiting groove cooperates with the interior of the fixing portion 1. After the fixing tube 201 is installed inside the mounting shell 101 and the fixing shell 102, the limiting groove is used to limit the fixing tube 201 between the mounting shell 101 and the fixing shell 102, thereby preventing the fixing tube 201 from rotating after installation and improving the stability of the fixing tube 201.

[0025] See also Figure 4、 Figure 6 and Figure 7 As shown, a support ridge 2021 is provided on the outer edge of the infusion rod 202, and the support ridge 2021 is located between the infusion rod 202 and the drainage rod 203. The support ridge 2021 provides a guide channel and support for the liquid medicine extracted from the drainage rod 203, ensuring the normal discharge of the liquid medicine.

[0026] See also Figure 5 As shown, a spherical liquid accumulation chamber 2031 is provided at the lower end of the drainage rod 203. The interior of the liquid accumulation chamber 2031 is connected to another fixed tube 201 through a hose. The extracted liquid medicine is then collected through the guide channel between the supporting ridges 2021 and enters the interior of the liquid accumulation chamber 2031 for collection, thereby realizing the collection of the discharged liquid medicine.

[0027] See also Figure 7 As shown, a spray groove 2051 is provided inside the fixed cover 205, and the interior of the spray groove 2051 is connected to the infusion pole 202. The liquid medicine is sprayed to the affected area through the interior of the spray groove 2051 inside the fixed cover 205 after the internal barrel of the infusion pole 202. At the same time, the interior of the spray groove 2051 cooperates with the camera 206, so that when the liquid medicine is sprayed through the interior of the spray groove 2051, the working camera 206 can be cooled by the flowing liquid medicine, thereby ensuring that the camera 206 is at an optimal working temperature.

[0028] See also Figure 7 As shown, a guide groove 2052 is further provided on the outer edge of the fixed cover 205. The interior of the guide groove 2052 cooperates with the fixed tube 201 and the infusion pole 202. A plurality of guide grooves 2052 are provided. The extraction pressure inside the discharge pole 203 is distributed through the plurality of guide grooves 2052. This prevents the pressure from being concentrated in one place when extracting the liquid medicine, causing the affected part to be adsorbed on the fixed cover 205. As a result, the affected part is subjected to the adsorption force and enters the interior of the fixed cover 205, causing damage, thereby ensuring the safety of the operation when extracting the liquid medicine. The coordinated design of the diversion groove 2052 and the injection groove 2051 optimizes the distribution path of the liquid medicine, making the flushing range more concentrated while avoiding damage to the mucosal tissue of the affected area caused by sudden pressure increase; See also Figure 7 As shown, the outer edge of the fixed cover 205 is provided with a plurality of raised friction ridges. The friction ridges enable the fixed cover 205 to be placed on the affected area, and the raised friction ridges can produce slight friction with the affected area by moving the fixed cover 205 to cause the material attached to the affected area to fall off or transfer, thereby making it easier to observe the condition of the affected area and perform better irrigation operations on the attached position.

[0029] See also Figure 3 、 Figure 8 and Figure 10As shown, the fixing part 1 includes a mounting shell 101, a fixing shell 102, a fixing bolt 103, a locking piece 104, a control button 105, a docking plug 106 and a connecting pipe 107. The interior of the mounting shell 101 matches the outer edge of the fixing tube 201, and the fixing shell 102 is assembled on one side of the mounting shell 101. One end of the fixing bolt 103 is rotatably set in the interior of the mounting shell 101, and the other end of the fixing bolt 103 is threadedly connected to the interior of the fixing shell 102. The locking piece 104 is fixedly connected to one side of the mounting shell 101, and the interior of the locking piece 104 matches the interior of the mounting shell 101. The control button 105 is fixedly set on the other side of the mounting shell 101. The docking plug 106 is fixedly connected to the lower end of the mounting shell 101, and the docking plug 106 is electrically connected to the control button 105 and the camera 206. One end of the connecting pipe 107 is plugged into the lower end of the fixing tube 201 and the docking plug 106, and the other end of the connecting pipe 107 is connected to the storage portion 3. The mounting housing 101 and the fixed housing 102 are assembled into a handle, which improves the convenience of the operator when holding the handle. Since the control button 105 is arranged on one side of the fixed housing 102, the operator's fingers can more easily press the control button 105, further improving the convenience of operation. When maintaining the fixed part 1, it is only necessary to rotate the fixing bolt 103 so that the fixing bolt 103 releases the fixed connection with the fixed shell 102, and then push the fixed shell 102 upward to separate the fixed shell 102 from the locking piece 104. Then, the fixed shell 102 can be removed to expose the two internal fixed shells 102, making it easier to remove the fixed shell 102, further improving the convenience of maintenance.

[0030] See also Figure 1 and Figure 9As shown, the storage portion 3 includes a fixed base 301, an extraction box 302, an extraction pump 303, a water storage tank 304, a heating base 305, a water pump 306, a control panel 307 and a connecting base 308. The fixed base 301 is set in the placement area, the extraction box 302 is set inside one end of the fixed base 301, the extraction pump 303 is fixedly connected to the inside of the fixed base 301, and the output end of the extraction pump 303 is connected to the inside of the extraction box 302. The water storage tank 304 is set inside the other end of the fixed base 301, and the heating base 305 is connected to the inside of the connecting base 308. One end is connected to the interior of the water tank 304, the input end of the water pump 306 is connected to the interior of the heating seat 305, the control panel 307 is fixedly connected to the fixed seat 301, the control panel 307 is connected to the mains power, the control panel 307 is electrically connected to the extraction pump 303, the heating seat 305, and the water pump 306, the interior of the connecting seat 308 is electrically connected to the control panel 307, the interior of the connecting seat 308 is also connected to the input end of the extraction pump 303, and the interior of the connecting seat 308 is connected to the output end of the water pump 306.

[0031] The fixing base 301 is set in the placement area, and the extraction box 302 and the water storage tank 304 are installed inside the fixing base 301. The control panel 307 receives the operation signal of the control button 105 and the image data of the camera 206. The corresponding extraction pump 303 and water delivery pump 306 are controlled by the operation signal to adjust the flow rate in multiple gears. The flushing intensity can be flexibly switched according to the image feedback, which significantly improves the operation accuracy and safety. It is particularly suitable for the refined treatment of narrow or sensitive areas of the digestive tract of children. When the extraction pump 303 is running, a negative pressure is formed inside the connecting pipe 107 and the discharge rod 203, thereby extracting the liquid medicine inside the discharge rod 203; When the water delivery pump 306 is running, a negative pressure is formed inside the heating seat 305, so that the negative pressure inside the heating seat 305 draws the medicinal liquid stored in the water tank 304, and the entering medicinal liquid is heated at a constant temperature by the heating seat 305. The heated medicinal liquid can ensure the stability of the active ingredients of the medicinal liquid during the treatment process, and can also effectively relieve the discomfort of children caused by temperature difference, and improve treatment compliance; the medicinal liquid heated inside the heating seat 305 is pumped to the inside of the discharge rod 203 by the water delivery pump 306 and then discharged to the affected area, and the affected area is rinsed and irrigated with the medicinal liquid.

[0032] See also Figure 9As shown, the interior of the heating seat 305 is provided with a curved water guide groove, and the interior of the water guide groove is fixedly provided with a matching curved electric heating rod, and the outer edge of the electric heating rod is provided with spiral guide fins. The liquid flow path forms a continuous circuitous path through multiple levels of bending, wherein the spiral guide fins further increase the flow path of the liquid, and can also increase the contact area between the electric heating rod and the liquid, thereby enhancing the heat exchange efficiency. When the medicine flows through the water guide groove, the curved flow channel structure naturally prolongs the action process of the liquid and the electric heating rod, and cooperates with the temperature control system to achieve continuous and uniform heating of the medicine during the flow process, thereby ensuring that the preset heating effect is achieved.

[0033] The working principle of the present invention is as follows: when performing the lavage operation, the fixed cover 205 of the lavage part 2 is inserted into the patient's digestive tract, and the internal conditions of the patient's digestive tract are observed through the camera 206. According to the internal condition of the patient's digestive tract, the irrigation liquid in the storage part 3 is pumped into the infusion rod 202 through the fixed part 1. The irrigation liquid in the infusion rod 202 is transported to the fixed cover 205 and discharged to the affected area for flushing, thus completing the infusion of the liquid. After a predetermined amount of liquid medicine is poured into the patient, the reservoir 3 is controlled to draw liquid from the drain rod 203, creating a negative pressure inside the drain rod 203. The negative pressure inside the drain rod 203 is used to draw liquid medicine from the fixed cover 205, allowing the liquid medicine to be drawn out of the patient's body through the drain rod 203 and then discharged into the reservoir 3 for storage. This completes the process of extracting liquid medicine. After the irrigation operation is completed and the irrigation part 2 is to be maintained, it is only necessary to separate the fixed cover 205 from the infusion rod 202, and then rotate the fixed ring 204 to separate the fixed ring 204 from the drainage rod 203. Then the drainage rod 203 can be pulled out along the infusion rod 202, so that the drainage rod 203 and the infusion rod 202 are separated. At the same time, the infusion rod 202 can also be separated from the fixed tube 201, thereby facilitating the maintenance and cleaning of the drainage rod 203 and the infusion rod 202, and realizing convenient cleaning and maintenance of the equipment.

[0034] Example 2 A microfluidic chip is integrated inside the injection slot 2051, and a piezoelectric ceramic driver is provided inside the microfluidic chip. When the liquid medicine passes through the microfluidic chip inside the injection slot 2051, the high-frequency vibration of the piezoelectric ceramic driver cuts the continuous liquid flow into uniform droplets, thereby changing the liquid medicine from "continuous injection" to "controllable droplets", greatly reducing the impact on children's fragile mucous membranes.

[0035] Similarly, a microfluidic chip is provided inside the guide groove 2052, and the negative pressure inside the guide groove 2052 is adjusted by a piezoelectric ceramic driver, so that the liquid flow passing through the guide groove 2052 can achieve "single drop extraction" to further avoid mucosal adsorption damage caused by continuous negative pressure.

[0036] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
