Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an enteral nutrition tube flushing filter. Background Art

[0002] After using the enteral nutrition tube for a period of time, sediment, residue or bacteria often form in the tube lumen. If it is not cleaned in time, it may cause complications such as tube blockage and infection. Therefore, it is necessary to flush the enteral nutrition tube regularly to keep the tube unobstructed and hygienic. Traditional enteral nutrition tube flushing often requires the use of a syringe or manual irrigation, which is cumbersome and easy to cause contamination. In addition, since bacteria may exist in the flushing fluid, in some special cases, the flushing fluid needs to be purified and filtered through a filter.

[0003] At present, traditional enteral nutrition tube flushing filters mostly use a built-in filtering structure for filtering. Impurities filtered out of the flushing liquid will be deposited on the filtering structure. Therefore, the filtering structure inside the filter is prone to serious blockage after long-term use, resulting in the flushing liquid not flowing smoothly through the filter, affecting the efficiency of cleaning the enteral nutrition tube. Therefore, an enteral nutrition tube flushing filter is proposed. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 The utility model provides an embodiment: an enteral nutrition tube flushing filter, comprising a housing 1, a nutrition tube 3 is fixedly connected to the left side of the housing 1, a liquid inlet pipe 2 is fixedly connected to the right side of the housing 1, the liquid inlet pipe 2 is connected to an external flushing liquid storage device through a pipeline, and the flushing liquid is continuously delivered to the inside of the liquid inlet pipe 2 by a water pump, the end of the nutrition tube 3 is connected to the enteral nutrition tube, the filtered flushing liquid will pass through the inside of the housing 1 into the nutrition tube 3, and flow into the inside of the enteral nutrition tube for flushing. A waste pipe 4 is fixedly connected to the front side of the housing 1, and the impurities filtered out of the flushing liquid will be entrained by the flushing liquid through the waste pipe 4 and discharged from the inside of the filter.

[0030] Reference Figure 1 , Figure 2 and Figure 4, a sealing block 5 is slidably connected to the top of the box body 1, a filter screen 6 is fixedly connected to the bottom of the sealing block 5, a cleaning assembly is installed on the right side of the box body 1, a fixed block 7 is fixedly connected to the inner bottom wall of the sealing block 5, and positioning rods 8 are fixedly connected on both sides of the fixed block 7. The outer periphery of the positioning rod 8 is slidably connected to the insertion rod 9, and a spring 10 is sleeved in the middle of the outer periphery of the positioning rod 8. A pull rod 11 is slidably connected to the middle side of the top of the sealing block 5, and the bottom end of the pull rod 11 is fixedly connected to a limit plate 12, and a connecting rod 13 is arranged between the limit plate 12 and the insertion rod 9. Pull the handle part on the top of the pull rod 11 upward, so that the pull rod 11 moves upward and drives the limit plate 12 to move upward together. At this time, the limit plate 12 will synchronously pull the two connecting rods 13 together, and drive the two insertion rods 9 to move toward each other through the connecting rod 13. At the same time, the insertion rod 9 will also compress the spring 10 when moving along the positioning rod 8 until the insertion rod 9 and the hole inside the box body 1 are separated. At this time, the sealing block 5 and the housing 1 are in an unlocked state, and then the sealing block 5 and the filter screen 6 can be pulled out from the housing 1, and then the filter screen 6 can be cleaned or replaced.

[0031] Reference Figure 2 and Figure 4 , the outer periphery of the plug rod 9 passes through the sealing block 5 and is inserted into the box body 1, so that the sealing block 5 can be fixed inside the box body 1 by means of the plug-in cooperation between the plug rod 9 and the box body 1, ensuring that the filter screen 6 can be stably placed inside the filter, and at the same time, a sealing ring is provided at the gap between the sealing block 5 and the box body 1 to prevent the leakage of the flushing liquid. The waste pipe 4 is located between the filter screen 6 and the liquid inlet pipe 2, so that the impurities blocked by the filter screen 6 will stay near the port of the waste pipe 4, and the impurities can be discharged by simply opening the valve on the waste pipe 4. One end of the connecting rod 13 is hinged to the edge of the limit plate 12, and the other end of the connecting rod 13 is hinged to the top of the plug rod 9. Through the connecting rod 13, the two plug rods 9 can be pulled synchronously when the limit plate 12 moves. One end of the spring 10 is fixedly connected to the end of the plug rod 9 close to the fixed block 7, and the other end of the spring 10 is fixedly connected to the outer wall of the fixed block 7. The end of the plug rod 9 can be tightly pressed by the spring 10 to prevent the plug rod 9 from being separated from the box body 1.

[0032] Reference Figure 1-Figure 3The cleaning assembly includes two guide rings 14, which are fixedly connected to the right side of the box body 1. Three movable frames 15 distributed in a circle are slidably connected between the two guide rings 14. A support frame 16 is fixedly connected to the side of the movable frame 15 away from the inner wall of the box body 1. A transmission shaft 17 is fixedly connected between the three support frames 16. An impeller 18 is fixedly connected to the end of the transmission shaft 17 away from the filter screen 6. A brush 19 is fixedly connected to the side of the movable frame 15 away from the transmission shaft 17. Guide wheels 20 are installed on the edges of both sides of the movable frame 15. When the flushing liquid enters the box body 1 through the liquid inlet pipe 2, the flushing liquid will contact the impeller 18 at the first time, and the flowing flushing liquid will drive the impeller 18 to rotate, so that the impeller 18 will drive the transmission shaft 17 and the support frame 16 to rotate, and then the movable frame 15 can perform a circular motion along the inner wall of one side of the box body 1 under the action of the guide wheel 20. The guide rings 14 on both sides ensure that the movable frame 15 will not deviate during the circular motion, and the brush 19 on the movable frame 15 can conveniently clean the impurities attached to the inside of the box 1. The outer periphery of the guide wheel 20 abuts against the inner wall of the box 1, so that the support structure composed of the movable frame 15, the support frame 16 and the transmission shaft 17 can move in the circular space on the left side of the box 1. The brush 19 abuts against the inner wall of the box 1. As the movable frame 15 drives the brush 19 to move in a circular motion inside the cylindrical workpiece on the left side of the box 1, the brush 19 will clean the impurities attached to its inner wall. The impeller 18 is located at the left end of the liquid inlet pipe 2, so that the flushing liquid flushed out of the impeller 18 can immediately transmit the impact force to the impeller 18, and then drive the impeller 18 to rotate.

[0033] Working principle: By connecting the external flushing liquid pipeline and the liquid inlet pipe 2, the flushing liquid is injected into the filter through the water pump. After that, the flushing liquid passes through the filter screen 6 and enters the nutrition tube 3 for cleaning. At the same time, the impurities contained in the flushing liquid will be blocked and collected by the filter screen 6. When the impurities on the filter screen 6 are seriously clogged, the user can pull up the handle on the top of the pull rod 11 to move the pull rod 11 upward and drive the limit plate 12 to move upward together. At this time, the limit plate 12 will synchronously pull the two connecting rods 13 together, and drive the two plug rods 9 to move toward each other through the connecting rod 13. At the same time, the plug rod 9 will also compress the spring 10 when moving along the positioning rod 8 until the plug rod 9 and the hole inside the box body 1 are disengaged. At this time, the sealing block 5 and the box body 1 are in an unlocked state, and then the sealing block 5 and the filter screen 6 can be pulled out from the inside of the box body 1, and then the filter screen 6 can be cleaned or replaced. During installation, it is only necessary to insert the sealing block 5 and the filter screen 6 into the box body 1 again, and loosen the pull rod 11 at the same time, so that the compressed spring 10 is reset to push the insertion rod 9 to move and be inserted into the box body 1 again, thereby completing the installation and fixation of the sealing block 5.

[0034] When the flushing liquid enters the interior of the housing 1 through the liquid inlet pipe 2, the flushing liquid will contact the impeller 18 at the first time, and the flowing flushing liquid will drive the impeller 18 to rotate, so that the impeller 18 will drive the transmission shaft 17 and the support frame 16 to rotate, and then the movable frame 15 can move in a circle along the inner wall of one side of the housing 1 under the action of the guide wheel 20. The guide rings 14 on both sides ensure that the movable frame 15 will not deviate during the circular motion, and the brush 19 on the movable frame 15 can conveniently clean the impurities attached to the interior of the housing 1. After the valve on the waste pipe 4 is opened, the flushing liquid will carry the cleaned impurities out of the filter from the waste pipe 4, and then the valve on the waste pipe 4 is closed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
