[0001] The present invention relates to the technical field of medical auxiliary devices, in particular to a gastric tube feeding tube flushing and extrusion device. Background Art

[0002] In modern medical care, gastric feeding tubes are used as an important auxiliary treatment tool and are widely used in patients who need long-term or short-term enteral nutrition support. However, as time goes by and the frequency of use increases, food residues, mucus and other impurities are easily accumulated inside the gastric feeding tubes, which not only affects the effect of nutrient delivery, but also may become a breeding ground for bacteria, increasing the risk of infection for patients. Therefore, how to effectively clean the inside of the gastric feeding tube and keep it clean and hygienic has become an urgent problem to be solved in clinical care. Traditional gastric feeding tube cleaning methods mostly rely on manual operations, such as flushing with a syringe, wiping with a long cotton swab, etc. These methods are not only inefficient, but also difficult to completely remove dirt on the tube wall. At the same time, they cause great damage to the fine structure inside the pipe, posing a safety hazard. In addition, due to the special structure and material limitations of gastric feeding tubes, some conventional cleaning equipment is not applicable, which further increases the difficulty and complexity of the cleaning work.

Throughout this application, unless otherwise specified, "plurality" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0042] See Figure 1-7 As shown, a gastric tube feeding tube flushing and extrusion device according to an embodiment of the present application includes:

[0043] A long tube 1 is used to extend into the interior of a gastric tube feeding tube. A gas channel 2 and a line channel 3 are provided inside the long tube 1. A miniature camera 4 is provided at one end of the long tube 1. The long tube 1 is provided with a first groove 5 and a second groove 6;

[0044] a control assembly, the control assembly being disposed at the other end of the long tube 1 and being in communication with the gas channel 2 and the line channel 3;

[0045] A cleaning component is provided at one end of the long tube 1 close to the miniature camera 4 and is used to flush the inner wall of the gastric tube and the feeding tube;

[0046] The conveying component is arranged on the side of the long tube 1 close to the cleaning component. The conveying component is slidingly connected to the side wall of the long tube 1. The conveying component is used to push the long tube 1 into the interior of the gastric tube and the feeding tube. The conveying component is electrically connected to the control component, the cleaning component, and the micro camera 4.

[0047] In some specific embodiments, the control component includes:

[0048] a box body 7, wherein the interior of the box body 7 is in communication with the circuit channel 3;

[0049] A control panel 8 is provided on the side wall of the box body 7 , and a mounting end of the control panel 8 is fixedly connected to the side wall of the box body 7 .

[0050] In some specific embodiments, a servo motor 9 is provided inside the box body 7, and the mounting end of the servo motor 9 is fixedly connected to the inner wall of the box body 7. An elastic airbag 10 is also provided inside the box body 7, and the telescopic end of the servo motor 9 abuts against the side wall of the elastic airbag 10. The telescopic end of the servo motor 9 is used to squeeze the elastic airbag 10, and the elastic airbag 10 is connected to the gas channel 2, and the control panel 8 is electrically connected to the servo motor 9.

[0051] It should be understood that the interior of the box body 7 is connected to the circuit channel 3, forming an electrical connection path to ensure power supply and signal transmission for the entire device. A control panel 8 is mounted on the side wall of the box body 7 and fixedly connected to it at its mounting end, facilitating operator control of the device while ensuring structural stability. A servo motor 9 is mounted and fixed to the inner wall of the box body 7. It serves as a power source and begins operation after receiving instructions from the control panel 8. When the state of the elastic airbag 10 needs to be adjusted, the servo motor 9 retracts and contracts according to the instructions. For example, when the elastic tube needs to be expanded to move particles within the long tube, the servo motor 9 extends; when expansion is not required, the servo motor 9 retracts. The elastic airbag 10 is located inside the box body 7 and connected to the gas channel 2. When the servo motor 9 extends, its retracted end abuts the side wall of the elastic airbag 10 and compresses the elastic airbag 10. As the elastic balloon 10 is squeezed, the gas within the balloon is transported into the elastic tube through the connected gas channel 2, causing the elastic tube to expand to match the inner diameter of the long tube, thereby pushing the particles inside the long tube to move, thereby assisting in cleaning the gastric feeding tube. The control panel 8 is electrically connected to the servo motor 9, and the operator inputs relevant commands through the control panel 8. For example, when the operator wishes to start the cleaning process and use the elastic tube to push the particles to move, they press the corresponding button on the control panel 8 or adjust the corresponding parameters. The command signal is transmitted to the servo motor 9 through the line channel 3. The servo motor 9 operates according to the command. Through this series of mechanical transmission and pneumatic processes, the elastic tube and the entire cleaning device are controlled, thereby achieving the purpose of effectively cleaning the interior of the gastric feeding tube. The expansion degree of the elastic tube and related cleaning parameters can also be flexibly adjusted according to actual needs.

[0052] In some specific embodiments, the cleaning component includes:

[0053] an electric rotating shaft 11, wherein the mounting end of the electric rotating shaft 11 is fixedly connected to the inner wall of the first groove 5, and the electric rotating shaft 11 is provided with two fixing grooves 12;

[0054] The cleaning ring 13 is sleeved on the outer side of the electric rotating shaft 11 , and the inner wall of the cleaning ring 13 is provided with a fixing block 14 matching the fixing groove 12 , and the side wall of the cleaning ring 13 is provided with a brush 15 .

[0055] In some specific embodiments, the cleaning assembly further includes an elastic tube 16 , which is fixedly connected to the inner wall of the second groove 6 , and the elastic tube 16 is in communication with the gas channel 2 .

[0056] In some specific embodiments, the electric rotating shaft 11 is electrically connected to the control panel 8 .

[0057] In some specific embodiments, the outer side wall of the elastic tube 16 is provided with a plurality of anti-slip bumps 17 .

[0058] It should be understood that the mounting end of the electric rotating shaft 11 is fixedly connected to the inner wall of the first groove 5 and is provided with two fixing grooves 12. When the device is activated, the control panel 8 issues a command, supplying power to the electric rotating shaft 11 through the circuit channel 3, causing it to begin rotating. Because the cleaning ring 13 is mounted on the outer side of the electric rotating shaft 11, and the fixing blocks 14 on the inner wall of the cleaning ring 13 mate with the fixing grooves 12 of the electric rotating shaft 11, the rotation of the electric rotating shaft 11 drives the cleaning ring 13 to rotate synchronously. This rotational motion enables the cleaning ring 13 to move in a circular motion around the electric rotating shaft 11 within the long tube 1, thereby thoroughly scrubbing the inner wall of the long tube 1. A brush 15 is installed on the side wall of the cleaning ring 13. As the electric rotating shaft 11 rotates, the brush 15 continuously contacts and rubs against the inner wall of the long tube 1. The brush 15 effectively removes dirt, residue, and other impurities adhering to the inner wall of the long tube 1, achieving a preliminary cleaning of the inner wall of the long tube 1. At the same time, the brush 15 can also agitate larger particles or sticky materials during rotation, freeing them from the tube wall and facilitating subsequent cleaning. An elastic tube 16 is fixedly connected to the inner wall of the second groove 6 and communicates with the gas passage 2. When further cleaning of particles or debris from the interior of the long tube 1 is required, the servo motor 9 in the control assembly responds to commands from the control panel 8 and operates. The telescopic end of the servo motor 9 compresses the elastic airbag 10, allowing the gas within the elastic airbag 10 to enter the elastic tube 16 through the gas passage 2. As the gas enters, the elastic tube 16 expands, and the multiple anti-slip bumps 17 on its outer wall increase friction with the inner wall of the long tube 1. As the elastic tube 16 expands, the electric rotating shaft 11 continues to rotate the cleaning ring 13. During rotation, the elastic tube 16 rolls along the inner wall of the long tube 1. The anti-slip bumps 17 help the elastic tube 16 better adhere to the tube wall and push particles inside the long tube 1 toward the opening of the long tube 1, thereby assisting in cleaning and pushing the particles.

[0059] The motorized rotating shaft 11 drives the cleaning ring 13 to rotate, allowing the brush 15 to thoroughly scrub the inner wall of the long tube 1, ensuring that every area is effectively cleaned. Compared with traditional single-directional or localized cleaning methods, this greatly improves cleaning efficiency and quality, and can more thoroughly remove dirt and residue. The design of the cleaning ring 13 allows it to penetrate every corner of the long tube 1. The brush 15 can carefully clean impurities on the tube wall, including some hard-to-reach areas, ensuring comprehensive and in-depth cleaning, helping to maintain the cleanliness of the interior of the long tube 1 and reducing the risk of bacterial growth and pipe blockage.

[0060] In some specific embodiments, the delivery assembly comprises:

[0061] A vehicle body 18, wherein a plurality of universal wheels 19 are provided at the bottom of the vehicle body 18;

[0062] An electric telescopic column 20 is provided on the top of the vehicle body 18 , and a bottom mounting end of the electric telescopic column 20 is fixedly connected to the top of the vehicle body 18 ;

[0063] A support assembly is provided on the top of the electric telescopic column 20 .

[0064] In some specific embodiments, the support assembly includes:

[0065] A support block 21, the bottom of which is fixedly connected to the telescopic end of the top of the electric telescopic column 20, and the support block 21 is provided with a transverse through hole 22, into which the long tube 1 extends;

[0066] The electric pulley 23 is symmetrically arranged on the top wall and the bottom wall inside the through hole 22. The mounting ends of the multiple electric pulleys 23 are fixedly connected to the inner wall of the through hole 22, and the multiple electric pulleys 23 are slidably connected to the side wall of the long tube 1.

[0067] In some specific embodiments, the plurality of electric pulleys 23 are electrically connected to the control panel 8 .

[0068] It should be understood that multiple universal wheels 19 are provided at the bottom of the vehicle body 18, providing excellent mobility. When the position of the nasogastric feeding tube cleaning device needs to be adjusted or moved, the operator can push the vehicle body 18 and use the universal wheels 19 to roll on the ground, thereby conveniently moving the device to the appropriate position to adapt to different usage scenarios and patient positioning requirements. The electric telescopic column 20 is disposed on the top of the vehicle body 18, and its bottom mounting end is fixedly connected to the top of the vehicle body 18. When the height of the long tube 1 needs to be adjusted to better mate with the patient's nasogastric feeding tube, the control panel 8 issues a command, providing power to the electric telescopic column 20 through the line channel 3, causing its telescopic end to telescope. The telescopic movement of the electric telescopic column 20 drives the support assembly and the long tube 1 fixed thereto to move up and down, thereby achieving precise adjustment of the height of the long tube 1 and ensuring that it can be accurately inserted into the patient's nasogastric feeding tube. The bottom of the support block 21 in the support assembly is fixedly connected to the top telescopic end of the electric telescopic column 20 and is provided with a transverse through-hole 22, into which the long tube 1 extends. Multiple motorized pulleys 23 are symmetrically positioned on the top and bottom walls of through-hole 22. The mounting ends of these pulleys 23 are fixedly connected to the inner wall of through-hole 22 and slidably connected to the sidewalls of tube 1. When tube 1 needs to be inserted deeper into or partially removed from a patient's nasogastric feeding tube, the motorized pulleys 23 operate in concert under the control of control panel 8. Driven by a motor, these pulleys 23 rotate, creating friction with the sidewalls of tube 1, allowing tube 1 to slide smoothly along through-hole 22. This allows for precise insertion and removal of tube 1 from the patient's nasogastric feeding tube, preventing excessive frictional damage between tube 1 and the patient's nasogastric feeding tube. Multiple universal wheels 19 enable the transport assembly to be easily moved across diverse medical environments, enabling convenient and efficient transfers between beds within a ward and between departments within a medical institution. This enhances the device's practicality and flexibility while reducing the labor of manual handling. A motorized telescopic column 20 precisely adjusts the height of tube 1 according to actual needs. The body positions, bed heights and insertion positions of gastric feeding tubes of different patients may be different. Through this height adjustment function, it can be ensured that the long tube 1 can always maintain the best docking state with the patient's gastric feeding tube, improve the cleaning effect and convenience of operation, and also help reduce misoperation and patient discomfort caused by height mismatch.
