[0002] A nasogastric tube, also known as a nasogastric tube or nasogastric feeding tube, is a medical device used to deliver food, nutrient solution or medication directly into the stomach, mainly used to provide nutrition and medication to patients who are unable to eat through the mouth.

[0003] When existing nasogastric feeding devices are delivering nutrients, large particles in the nutrients may cause blockage of the connecting tube. In order to avoid blockage of the connecting tube, a filter is installed inside the connecting tube. However, due to the large number of large particles, the large particles of nutrients cannot be effectively broken up. Therefore, after long-term use, large particles of nutrients will soon accumulate on the filter. At this time, the filter needs to be replaced, thereby increasing the frequency of filter replacement.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 and Figure 2 The utility model provides a technical solution: an intelligent heat preservation and anti-blocking nutrition nasogastric feeding device, comprising: a catheter 1 and a telescopic frame 7, the top of the catheter 1 is connected to a connecting pipe 2, the top of the connecting pipe 2 is connected to a filter tube 3, one side of the filter tube 3 is connected to a delivery pipe 4, and the end of the delivery pipe 4 away from the connecting pipe 2 is connected to a delivery pump 5; the outer surface of the connecting pipe 2 is connected to a fixing frame 6, and the telescopic frame 7 is connected to the fixing frame 6;

[0024] The top of the filter tube 3 is closed, and a driving motor 8 is installed on the top of the filter tube 3 through the outer shell. The output end of the driving motor 8 is connected with a crushing knife 9 through a coupling. The crushing knife 9 is located inside the filter tube 3, and a filter screen 10 is installed at the insertion end of the filter tube 3. The crushing knife 9 is located on the side of the filter screen 10 away from the connecting pipe 2. Connecting blocks 11 are installed on the outer sides of the driving motor 8, the filter tube 3 and the conveying pipe 4. One side of the connecting block 11 is connected with an insertion block 12. Fixed blocks 13 corresponding to the connecting blocks 11 are also provided on the connecting pipe 2 and the filter tube 3. The fixed block 13 has a through groove. The insertion block 12 extends outwards through the through groove. First movable blocks 15 and second movable blocks 16 are respectively arranged on the opposite sides of the insertion block 12. The first movable block 15 and the second movable block 16 are connected by a connecting rod. The first movable block 15, the second movable block 16 and the connecting rod together form a rectangular frame. A screw rod 14 is connected through one side of the fixed block 13. The inner end of the screw rod 14 is rotatably connected with the first movable block 15. A clamping block 17 is installed on the inner side of the second movable block 16. The insertion block 12 has a bayonet matching with the insertion block 12. An electric heating wire 18 is sleeved on the outer side of the conveying pipe 4.

[0025] During specific implementation, for this intelligent heat-insulating and anti-blocking nutritional nasal feeding device, when in use, the nutritional substances can be conveyed into the filter tube 3 through the conveying pipe 4 by the conveying pump 5. A driving motor 8 is installed on the top of the filter tube 3 through the outer shell, and the bottom of the driving motor 8 is connected with the crushing knife 9 through a coupling. Therefore, the driving motor 8 will drive the crushing knife 9 to rotate. Through the high-speed rotation of the crushing knife 9, the large-particle nutritional substances entering the filter tube 3 can be broken up. Then the nutritional substances will fall to the bottom of the filter tube 3. The large-particle nutritional substances can be filtered again through the filter screen 10 at the bottom of the filter tube 3. There will be no large-particle substances in the filtered nutritional substances, so that the nutritional substances can normally flow to the patient's stomach through the connecting pipe 2 and the catheter 1.

[0026] At the same time, when the filter screen 10 needs to be replaced, the screw rod 14 on the fixed block 13 at the end of the filter tube 3 close to the connecting pipe 2 can be rotated. Since the screw rod 14 is threadedly connected with the fixed block 13 and the screw rod 14 is connected with the first movable block 15 through a bearing, rotating the screw rod 14 at this time can drive the first movable block 15 to move, making the first movable block 15 move towards the insertion block 12. The movement of the first movable block 15 will push the second movable block 16 to move through the connecting rod, and drive the clamping block 17 to move through the second movable block 16, so that the clamping block 17 moves out of the card slot of the insertion block 12. At this time, there is no limit of the clamping block 17 on the insertion block 12, and then the insertion block 12 can be pulled upwards out of the through groove of the fixed block 13. At this time, the connecting pipe 2 and the filter tube 3 can be separated. Similarly, the above steps can be repeated to separate the conveying pipe 4 from the filter tube 3 and the driving motor 8 from the filter tube 3, and then the filter tube 3 can be replaced.

[0027] During installation, just repeat the above steps in reverse, so that the clamping block 17 is inserted into the card slot of the inserting block 12, so that the filter pipe 3 can be installed on the conveying pipe 4, and apply a force to insert the filter pipe 3 into the connecting pipe 2, so that the plugging end of the filter pipe 3 squeezes the sealing ring in the top groove of the connecting pipe 2, thereby increasing the sealing effect between the connecting pipe 2 and the filter pipe 3 and preventing the leakage of nutrients. Similarly, install the driving motor 8 on the top of the filter pipe 3 and the conveying pipe 4 on one side of the filter pipe 3. At this time, the filter pipe 3 and the filter screen 10 can be installed and fixed.

[0028] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As can be seen, during use, the driving motor 8 can drive the crushing knife 9 to rotate, and the crushing knife 9 can crush the nutrients. After crushing, the nutrients are filtered through the filter screen 10 in the filter pipe 3, thus avoiding the blockage of the conduit 1 caused by large particulate matter. Moreover, the filter screen 10 can be replaced according to requirements. At the same time, the electric heating wire 18 outside the conveying pipe 4 can heat and keep warm the nutrients in the conveying pipe 4.

[0029] The extending end of the telescopic frame 7 is provided with a clamp 19. The clamp 19 is rotationally connected to the telescopic frame 7 through a rotating shaft 20. One end of the rotating shaft 20 is sleeved with a gear 21. One side of the gear 21 abuts against a limiting block 22. A guiding block 23 is sleeved on the limiting block 22. The guiding block 23 is fixed on the clamp 19, and a movable spring 24 is connected between the guiding block 23 and the limiting block 22. A threaded rod 25 penetrates through the side wall of the fixed frame 6. The inner end of the threaded rod 25 is connected with a convex block 26 through a bearing. A plurality of card slots matching with the convex block 26 are formed on the telescopic frame 7. The plurality of card slots are evenly arranged at intervals along the length direction of the telescopic frame 7. The telescopic frame 7 and the fixed frame 6 form a telescopic rod structure, and the threaded rod 25 is threadedly connected with the fixed frame 6.

[0030] During specific implementation, for the intelligent heat-insulating and anti-blocking nutritional nasal feeding device, when it is necessary to fix the entire connecting pipe 2, the threaded rod 25 at the bottom of the fixed frame 6 can be rotated according to the installation distance of the connecting pipe 2. Since the threaded rod 25 is threadedly connected with the fixed frame 6 and the top of the threaded rod 25 is connected with the convex block 26 through a bearing, at this time, the convex block 26 can be driven by the threaded rod 25 to move outward from the fixed frame 6. At the same time, the convex block 26 will be separated from the card slot on the telescopic frame 7. Without the limiting effect of the convex block 26 on the telescopic frame 7, the telescopic frame 7 can be telescoped along the fixed frame 6, thus facilitating the adjustment of the fixing position of the connecting pipe 2;

[0031] Meanwhile, when it is necessary to adjust the fixing angle of the connecting pipe 2, the limit block 22 can be pulled to one side, so that the limit block 22 moves along the guide block 23 and squeezes the movable spring 24. At the same time, the limit block 22 will be separated from the gear 21 on the outer side of the rotating shaft 20. Without the limit of the limit block 22 on the gear 21, the rotating shaft 20 can rotate. The rotation of the rotating shaft 20 will drive the telescopic frame 7 on one side to rotate. Through the telescopic frame 7 and the fixed frame 6, the fixing angle of the connecting pipe 2 can be adjusted, so as to facilitate the user to adjust the installation direction of the connecting pipe 2;

[0032] When fixing the connecting pipe 2, only need to rotate the fixture 19. The fixture 19 is composed of a lead screw and a clamping block. The clamping block is driven by the lead screw to move, so that the clamping block can be clamped on the bracket of the hospital bed, thus facilitating the user to quickly fix the connecting pipe 2.

[0033] Refer to Figure 1 、 Figure 4 and Figure 5 It can be seen that during use, according to the usage requirements, the entire connecting pipe 2 can be quickly clamped and limited on one side of the hospital bed through the fixture 19, and the distance of the connecting pipe 2 can be adjusted through the telescopic frame 7 and the fixed frame 6. The rotating shaft 20 and the telescopic frame 7 can adjust the fixing direction of the connecting pipe 2, so as to meet the different usage requirements of the user.

[0034] In summary: When the intelligent heat preservation and anti-blocking nutritional nasal feeding device is used, the pipeline at the other end of the delivery pump 5 can be connected to the container for holding nutrients. Then, through the delivery pump 5, the nutrients can be transported into the delivery pipe 4, and after being heated by the electric heating wire 18, they will flow into the filter pipe 3. After filtration and crushing, they will flow into the connecting pipe 2, and finally flow into the patient's stomach through the catheter 1 at the bottom of the connecting pipe 2, thus facilitating the delivery of nutrients to the patient's stomach through the catheter 1 in the nasal cavity. This is the usage feature of the intelligent heat preservation and anti-blocking nutritional nasal feeding device. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
