Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-reflux nasogastric feeding tube. Background Art

[0002] Nasogastric feeding is a method of feeding the stomach by artificially inserting a gastric tube into the esophagus through the nasal cavity under special circumstances. The food is first ground into a paste using a grinder, and a large syringe is used to connect the large feeding port under the gastric tube connector. After the connection is secure, the push rod piston is manually pressurized to pump water and food into the patient's stomach to help patients who cannot swallow independently provide water and food, and maintain the body's metabolism, weight and nutrition.

[0003] When the existing nasogastric feeding tube is in use, when the nasogastric feeding supply to the patient is stopped, the nasogastric feeding tube still needs to be clamped by an external device to cut off the flow of the nasogastric feeding tube, thereby preventing the backflow of the liquid food inside the nasogastric feeding tube. However, the overall operation of the existing nasogastric feeding tube is relatively cumbersome, resulting in the problem of low convenience of the existing nasogastric feeding tube.

[0004] For this reason, the utility model launches a reflux-proof nasogastric feeding tube. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present invention provides an anti-reflux nasogastric tube, which can quickly cut off the loss inside the nasogastric tube by disconnecting the nasogastric tube, thereby achieving the advantage of anti-reflux of the nasogastric tube and solving the problems raised in the background technology.

[0009] Preferably, the outer surface of one end of the tube body is slidably connected to a threaded sleeve, and the inner wall of the threaded sleeve is provided with an internal thread.

[0010] Preferably, the outer surface of each end of the tube body is provided with a thread.

[0011] Preferably, the fixed block is rotatably connected to a screw rod, the threads at both ends of the screw rod have opposite rotation directions, and one end of the screw rod passes through the fixed block, and one end of the fixed block is fixedly connected to an adjustment knob, the screw rod passes through the extension block and is threadedly connected to the extension block, and the extension block is slidably connected to the inner wall of the fixed block, and the extension block is fixedly connected to the other side of the lifting plate.

When in use, one end of the tube body 1 is docked with one end of the tube body 2, and the threaded sleeve is threadedly connected to the thread on the outer surface of the first end of the tube body by sliding the threaded sleeve, thereby completing the assembly of the nasogastric tube. In the process of connecting the tube body 1 with the second tube body, the connecting tube provided inside the first end of the tube body 1 will be inserted into the interior of the second tube body, and in the process of inserting the second tube body, one end of the connecting tube will contact the sealing bead 2 inside the second tube body, thereby pushing the other end of the connecting tube back into the interior of the first tube body.

Its arc-shaped groove can fit closely with the shape of the external connecting part, providing uniform clamping force, thereby strengthening the connection between the tube body 1 and the syringe port, thereby ensuring that the nasogastric tube will not overflow from the port when supplying liquid food.

[0026] Among them, one end of the tube body 1 is provided with a tube body 2 8, the inner wall of the tube body 2 8 is fixedly connected with a fixed ring 2 9, the fixed ring 29 is fixedly connected with a connecting spring 2 10, one end of the connecting spring 2 10 is fixedly connected with a sealing bead 2 11, the sealing bead 2 11 is abutted with a connecting block 2 12, and the connecting block 2 12 is fixedly installed with the inner wall of the tube body 2 8.

[0030] The number of the clamping plates 17 is two, and the two clamping plates 17 are symmetrically arranged with respect to the center of the fixing block 15 .

[0031] Working principle: When in use, the nasogastric feeding tube consists of two main parts: tube body 1 and tube body 2 8. First, one end of tube body 1 is docked with one end of tube body 2 8, and then the sliding threaded sleeve 13 is used to tightly connect with the thread on the outer surface of tube body 1, so as to firmly combine into a complete nasogastric feeding tube. During the docking process, the pre-installed connecting tube 7 inside tube body 1 will automatically insert into the interior of tube body 2 8. As tube body 2 8 goes deeper, its tip will touch the sealing bead 2 11 inside tube body 1. This contact causes the other end of the connecting tube 7 to retreat backward in tube body 1, thereby releasing the contact with the sealing bead 14 at the other end of tube body 1. This process promotes the sealing bead 14 and the sealing bead 2 11 are pushed in the initial compression state of connecting spring 1 3 and connecting spring 2 10 respectively, and are separated from the abutment state of connecting block 1 5 and connecting block 2 12 corresponding to them, thereby achieving unobstructed flow between tube body 1 and tube body 2 8, facilitating the smooth passage of liquid food. When the nasogastric feeding process is over and it is necessary to stop the liquid food supply, the above assembly steps are reversed, that is, the tube body 1 and the tube body 2 8 are separated, and the sealing beads 1 4 and the sealing beads 2 11 will automatically reset under the elastic force of connecting spring 1 3 and connecting spring 2 10, and will be tightly abutted against the connecting block 1 5 and the connecting block 2 12 again, forming an effective sealing barrier, effectively preventing the reflux of liquid food, and ensuring the safety and hygiene of use.

[0032] At the same time, when tube body 1 and tube body 2 8 are successfully docked and assembled, the other end of tube body 1 will be inserted into the port of the syringe. At this time, by operating the adjusting knob 20, the user can easily rotate it, thereby driving the screw 19 tightly connected to it to rotate. As the screw 19 rotates, the two extension blocks 18 mounted on the screw and threadedly connected to it will move along the axial direction of the screw. These movements are in opposite directions, that is, the two extension blocks gradually approach the center of the screw. Since the extension block 18 is connected to the clamping plate 17, as the extension block moves, the clamping plate 17 will also move closer to the center of the screw 19. Finally, the inner surface of the clamping plate 17 will fit tightly with the outer surface of the other end of tube body 1, forming an effective clamping effect. This clamping mechanism not only strengthens the connection strength between tube body 1 and the syringe port, but also significantly reduces the overflow from the port that may occur during the later liquid food supply process, thereby improving the safety and reliability of the nasogastric feeding process.
