Description

Technical Field

[0001] This utility model relates to the field of flushing filter technology, specifically to an enteral feeding tube flushing filter. Background Technology

[0002] In clinical medicine, enteral nutrition support is an important means of providing necessary nutrients to patients who are unable to eat normally or whose food intake is insufficient. Enteral nutrition tubes are the key tools for achieving this support. They can deliver nutrient solutions directly into the patient's intestines to meet the patient's nutritional needs and play a vital role in the patient's recovery.

[0003] In existing technologies, impurities and incompletely dissolved particles in the nutrient solution can easily deposit and accumulate in the enteral feeding tube, necessitating flushing. The cleaning solution used for flushing is mostly physiological saline, but physiological saline may be contaminated with minute impurities during production, storage, and transportation. When this impurity-containing cleaning solution is used to flush the feeding tube, the impurities enter the tube along with the cleaning solution, further causing blockage. Most existing flushing filters are equipped with only a single filter plate; once the filter plate becomes clogged, flushing cannot proceed normally and must be stopped for replacement, thus affecting the cleaning effect of the feeding tube. Therefore, those skilled in the art provide an enteral feeding tube flushing filter to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an enteral feeding tube flushing filter to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an enteral nutrition tube flushing filter, including a flushing filter body and a filter plate. A control panel is installed on the top of the flushing filter body. An inlet pipe is fixedly connected to the inlet end of the flushing filter body. A first drain pipe is fixedly connected to the outlet end of the flushing filter body. A second drain pipe is provided at the end of the first drain pipe away from the flushing filter body. A limiting component is provided between the first drain pipe and the second drain pipe. A first filtration mechanism and a second filtration mechanism for replacing the filter plate are respectively provided inside the limiting component. Filter plates are provided inside both the first filtration mechanism and the second filtration mechanism. A power supply terminal is reserved on the outer wall of the flushing filter body. A power cord is fixedly connected to the input end of the power supply terminal.

[0006] Preferably, the limiting component includes a mounting frame, with the end of the first drain pipe away from the main body of the flushing filter located inside the mounting frame, and the end of the second drain pipe near the first drain pipe located inside the mounting frame. Two fixed brackets are symmetrically fixedly connected to both the upper and lower ends of the mounting frame, and a first electric push rod is fixedly connected inside each pair of fixed brackets. A connecting bracket is slidably sleeved inside the mounting frame.

[0007] Preferably, the upper and lower ends of the connecting bracket are fixedly connected to guide frames, the guide frames are slidably connected to the mounting frame, the telescopic ends of the two first electric push rods are fixedly connected to the outer side walls of the two guide frames, and four magnetic cover plates are symmetrically fixedly connected to the outer side walls of the mounting frame.

[0008] Preferably, the connecting bracket has two filter plates slidably sleeved inside, and the outer walls of the two filter plates are respectively provided with a first filtration mechanism and a second filtration mechanism. The first filtration mechanism includes two first corrugated tubes symmetrically fixedly connected to the outer wall of one of the filter plates. A first adsorption tube is fixedly connected to the side of the two first corrugated tubes that is far away from each other, and a first magnetic adsorption circular plate is magnetically connected to the side of the two first adsorption tubes that is far away from the first corrugated tubes.

[0009] Preferably, a first limiting bracket is fixedly connected to the center of the outer wall of each of the two first magnetic circular plates, and a second electric push rod is embedded inside the connecting bracket. The telescopic end of the second electric push rod is fixedly connected to the opposite side of the two first limiting brackets.

[0010] Preferably, the second filtration mechanism includes two second corrugated tubes symmetrically and fixedly connected to the outer wall of another filter plate. A second adsorption tube is fixedly connected to the side of the two second corrugated tubes that is far away from each other. A second magnetic circular plate is magnetically connected to the side of the two second adsorption tubes that is far away from the second corrugated tubes. A first sealing ring and a second sealing ring are embedded in the inner wall of the two second adsorption tubes and the two first adsorption tubes.

[0011] Preferably, a second limiting bracket is fixedly connected to the center of the outer wall of each of the two second magnetic circular plates, and a third electric push rod is embedded inside the connecting bracket on one side of the second electric push rod. The telescopic end of the third electric push rod is fixedly connected to the opposite side of the two second limiting brackets.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model has a first filter mechanism and a second filter mechanism installed inside the mounting frame, and both the first filter mechanism and the second filter mechanism are equipped with filter plates. When one of the filter plates becomes clogged due to use (assuming it is the second filter mechanism), the user can move the first filter mechanism to the center of the mounting frame by moving the connecting bracket, while the second filter mechanism is located at the other end inside the mounting frame. In this way, the flushing filter body can continue to be used without stopping the machine.

[0014] The second electric push rod telescopic end drives the two first adsorption tubes to move and stretches the first corrugated pipe. At this time, the first and second sealing rings located inside the first adsorption tubes will be compressed by the first and second drain pipes until the first adsorption tubes move to the corresponding positions. At this time, the first and second sealing rings can play a role in increasing the seal. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figures 1-8 As shown, this utility model provides a technical solution: an enteral nutrition tube flushing filter, including a flushing filter body 1 and a filter plate 8. A control panel 2 is installed on the top of the flushing filter body 1. An inlet pipe 3 is fixedly connected to the inlet end of the flushing filter body 1. A first drain pipe 4 is fixedly connected to the outlet end of the flushing filter body 1. A second drain pipe 6 is provided at the end of the first drain pipe 4 away from the flushing filter body 1. A limiting component 5 is provided between the first drain pipe 4 and the second drain pipe 6. A first filtration mechanism 9 and a second filtration mechanism 10 for replacing the filter plate 8 are respectively provided inside the limiting component 5. Filter plates 8 are provided inside both the first filtration mechanism 9 and the second filtration mechanism 10. A power supply terminal 7 is reserved on the outer wall of the flushing filter body 1. A power cord 71 is fixedly connected to the access end of the power supply terminal 7.

[0027] It should be noted that the inlet pipe 3 and the first outlet pipe 4 serve as the inlet and outlet channels, respectively, ensuring the smooth flow of nutrient solution into and out of the flushing filter body 1 and ensuring the stable operation of the flushing filtration process. The limiting component 5 connects the first outlet pipe 4 and the second outlet pipe 6, serving as a connection and positioning function to ensure the stability of the outlet pipe connection and prevent liquid leakage. The dual filtration mechanism is used alternately. When one of the internal filter plates 8 needs to be replaced or cleaned, the other can continue to work without affecting the overall flushing filtration process, reducing equipment downtime and improving equipment utilization. The power supply terminal 7 and the power cord 71 provide stable power support for the flushing filter body 1, ensuring the normal operation of the equipment. When in use, a waste discharge pipe needs to be installed on the outer wall of the first outlet pipe 4. Impurities in the flushing liquid are blocked by the filter plate 8. After the nutrient tube is flushed, it needs to be separated from the nutrient tube. Therefore, when flushing liquid is introduced into the flushing filter body 1 again through the inlet pipe 3, impurities can be flushed out through the waste discharge pipe, thereby avoiding accumulation.

[0028] As one implementation method in this embodiment, please refer to Figures 3-5 As shown, the limiting component 5 includes a mounting frame 51. The end of the first drain pipe 4 away from the flushing filter body 1 is located inside the mounting frame 51. The end of the second drain pipe 6 near the first drain pipe 4 is located inside the mounting frame 51. Two fixed brackets 52 are symmetrically fixedly connected to both the upper and lower ends of the mounting frame 51. A first electric push rod 53 is fixedly connected inside each pair of fixed brackets 52. A connecting bracket 55 is slidably sleeved inside the mounting frame 51.

[0029] It should be noted that the fixed bracket 52 is symmetrically fixed at the upper and lower ends of the mounting bracket 51, providing a stable mounting base for the first electric push rod 53, enhancing the structural strength and stability of the entire limiting assembly 5, and enabling it to withstand certain external forces, preventing loosening or shaking during use. Through electric control, the position of the connecting bracket 55 can be easily and quickly adjusted, thereby controlling the connection status of the first drain pipe 4 and the second drain pipe 6, realizing automated operation, reducing manual intervention, and improving work efficiency.

[0030] As one implementation method in this embodiment, please refer to Figures 3-5 As shown, guide frames 551 are fixedly connected to both the upper and lower ends of the connecting bracket 55. The guide frames 551 are slidably connected to the mounting bracket 51. The telescopic ends of the two first electric push rods 53 are fixedly connected to the outer side walls of the two guide frames 551. Four magnetic cover plates 54 are symmetrically fixedly connected to the outer side walls of the mounting bracket 51.

[0031] It should be noted that when the first electric push rod 53 pushes or pulls the connecting bracket 55, the guide frame 551 can ensure that it moves stably along the predetermined trajectory, avoiding deviation or shaking, thereby ensuring the accuracy of the connection position of the first drain pipe 4 and the second drain pipe 6, reducing the risk of liquid leakage caused by position deviation, and ensuring the sealing and stability of the rinsing and filtration process. The four magnetic cover plates 54 symmetrically fixed on the outer wall of the mounting frame 51 not only protect the internal structure and prevent dust, impurities and other contaminants from entering and affecting the performance of the equipment, but also can be easily opened and closed by magnetic attraction when maintenance or repair is required, facilitating the operation of the internal components.

[0032] As one implementation method in this embodiment, please refer to Figures 4-6 As shown, two filter plates 8 are slidably sleeved inside the connecting bracket 55. The outer walls of the two filter plates 8 are respectively provided with a first filtration mechanism 9 and a second filtration mechanism 10. The first filtration mechanism 9 includes two first corrugated tubes 92 symmetrically fixedly connected to the outer wall of one of the filter plates 8. A first adsorption tube 93 is fixedly connected to the side of the two first corrugated tubes 92 that is far away from each other. A first magnetic adsorption circular plate 94 is magnetically connected to the side of the two first adsorption tubes 93 that is far away from the first corrugated tubes 92. A first limiting bracket 95 is fixedly connected to the center of the outer wall of each of the two first magnetic adsorption circular plates 94. A second electric push rod 91 is embedded inside the connecting bracket 55. The telescopic end of the second electric push rod 91 is fixedly connected to the side of the two first limiting brackets 95 opposite to each other.

[0033] It should be noted that two filter plates 8 are slidably fitted inside the connecting bracket 55. Together with the first filtration mechanism 9 and the second filtration mechanism 10, this allows for alternating filtration by the two filter plates. When the filtration efficiency of one filter plate 8 decreases due to impurity accumulation, the other filter plate 8 can be immediately put into use, ensuring the continuity of the rinsing and filtration process, reducing equipment downtime for maintenance, and improving work efficiency. In the first filtration mechanism 9, the first corrugated pipe 92 has elastic telescopic characteristics, allowing the first adsorption pipe 93 to move flexibly when the second electric push rod 91 pushes the first limiting bracket 95, facilitating the movement of the filter plates. The installation, disassembly, and replacement of filter plate 8 are simple and quick. The first adsorption tube 93 is magnetically connected to the first magnetic circular plate 94. This connection method is stable and easy to disassemble. When it is necessary to clean or replace filter plate 8, the first adsorption tube 93 can be easily separated from the first magnetic circular plate 94, reducing maintenance difficulty and cost. The telescopic end of the second electric push rod 91 is fixedly connected to the two first limit brackets 95. The position of the first adsorption tube 93 can be precisely adjusted through electric control, thereby controlling the position of filter plate 8, realizing automated operation, reducing manual intervention, and improving the accuracy and efficiency of operation.

[0034] As one implementation method in this embodiment, please refer to Figures 5-8As shown, the second filtration mechanism 10 includes two second corrugated tubes 102 symmetrically fixedly connected to the outer wall of another filter plate 8. A second adsorption tube 103 is fixedly connected to the side of the two second corrugated tubes 102 that is far away from each other. A second magnetic circular plate 104 is magnetically connected to the side of the two second adsorption tubes 103 that is far away from the second corrugated tubes 102. A first sealing ring 106 and a second sealing ring 107 are embedded in the inner wall of the two second adsorption tubes 103 and the two first adsorption tubes 93. A second limiting bracket 105 is fixedly connected to the center of the outer wall of the two second magnetic circular plates 104. A third electric push rod 101 is embedded in the inside of the connecting bracket 55 on one side of the second electric push rod 91. The telescopic end of the third electric push rod 101 is fixedly connected to the side of the two second limiting brackets 105 opposite to it.

[0035] It should be noted that the two second corrugated pipes 102 are connected to the second adsorption pipes 103, and together with the third electric push rod 101, the filter plate 8 can be moved and its position adjusted flexibly. The third electric push rod 101 can precisely control the second limit bracket 105, thereby driving the second adsorption pipes 103 and the filter plate 8 to work alternately with the filter plate 8 of the first filtration mechanism 9, ensuring that the rinsing and filtration process is uninterrupted, greatly improving the operating efficiency of the equipment and reducing downtime caused by filter plate replacement or maintenance. The second adsorption pipes 103 are magnetically connected to the second magnetic circular plate 104. This connection method is convenient and quick. When the filter plate 8 needs to be replaced or cleaned, it can be quickly separated, reducing the difficulty and complexity of operation and saving manpower and time costs. The first sealing ring 106 and the second sealing ring 107 embedded in the inner walls of the two second adsorption pipes 103 and the two first adsorption pipes 93 enhance the sealing of the connection, effectively prevent liquid leakage during the rinsing process, ensure the stability and safety of the rinsing and filtration, and avoid equipment damage or waste of nutrient solution due to leakage.

[0036] Working principle: When the enteral feeding tube flushing filter is working, the nutrient solution enters the flushing filter body 1 from the inlet pipe 3 for preliminary treatment and is discharged through the first drain pipe 4. When one of the filter plates 8 becomes blocked (assuming it is the filter plate 8 of the second filter mechanism 10), since the mounting frame 51 in the limiting component 5 is equipped with the first filter mechanism 9 and the second filter mechanism 10, both of which are equipped with filter plates 8, the guide frame 551 can be pushed by the telescopic end of the first electric push rod 53, thereby driving the connecting bracket 55 to slide in the mounting frame 51, moving the first filter mechanism 9 to the center of the mounting frame 51, while the blocked second filter mechanism 10 moves to the other end inside the mounting frame 51, so that the flushing filter body 1 can continue to be used without stopping the machine.

[0037] During the switching of filter plate 8, for the newly put into use first filtration mechanism 9, the two first limiting brackets 95 are moved by the extension end of the second electric push rod 91, which in turn causes the two first adsorption tubes 93 to move and stretch the first corrugated pipe 92. At this time, the first sealing ring 106 and the second sealing ring 107 located on the inner wall of the first adsorption tube 93 will be compressed by the first drain pipe 4 and the second drain pipe 6 until the first adsorption tube 93 moves to the corresponding position. The first sealing ring 106 and the second sealing ring 107 play a role in increasing the seal, ensuring the stability and sealing of the rinsing filtration process, ensuring the normal discharge of nutrient solution, realizing continuous filtration without stopping the machine, improving work efficiency, and reducing maintenance costs.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
