[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a nasogastric feeding device for mixing and administering oral medications to prevent blockage. The device includes a medicine cup 1, with a three-way tube 11 fixedly connected to the bottom of the cup 1. The three-way tube 11 connects to a nasogastric tube, allowing medication from the cup 1 to be delivered into the tube. A cover 12 is detachably connected to the top of the cup 1, facilitating opening and medication addition. The cup 1 contains a sieving component 2 and a grinding component 3. The sieving component 2 filters out particles from the medication, ensuring that the mixed medication does not contain excessively large particles, reducing the risk of blockage. The grinding component 3 grinds the medication into smaller particles or dissolves the medication to prevent blockage caused by solid particles.

[0032] Reference Figure 2 - Figure 3The sieving assembly 2 includes a sieve plate 21, which is slidably connected to the inner wall of the medicine cup 1. The surface of the sieve plate 21 has multiple arrayed through holes. The sieve plate 21 is used to sieve the medicine, allowing large particles to remain on its surface while small particles pass through and fall to the bottom of the medicine cup 1. A guide rod 22 is slidably connected to each through hole, and both ends of the guide rod 22 are fixedly connected to a fixing seat 23, which is fixedly connected to the side wall of the medicine cup 1. The fixing seat 23 secures the ends of the guide rod 22, guiding the movement of the sieve plate 21 and ensuring its stability. A return spring 24 elastically connects the fixing seat 23 to the bottom surface of the sieve plate 21, providing elastic support and causing the sieve plate 21 to vibrate under pressure. A protrusion 25, triangular in shape, is fixedly connected to the surface of the sieve plate 21.

[0033] Reference Figure 3 - Figure 4 The grinding assembly 3 includes a rotating shaft 31, which is movably connected to the surface of the sieve plate 21. The bottom end of the rotating shaft 31 is rotatably connected to the bottom surface of the medicine cup 1. A pin 32 is fixedly connected to the top of the rotating shaft 31. A fixed shaft 33 is fixedly connected to the side wall of the rotating shaft 31. A pressure roller 34 is rotatably connected to the end of the fixed shaft 33. Multiple sets of arrayed toothed plates 35 are fixedly connected to the side wall of the rotating shaft 31. The rotating shaft 31 drives the fixed shaft 33 and the pressure roller 34 to rotate, thereby crushing large particles of medicine on the surface of the sieve plate 21 into smaller particles. These smaller particles then pass through the surface of the sieve plate 21 and come into contact with the protrusions 25 during the rotation of the pressure roller 34. Under the action of the return spring 24, the sieve plate 21 vibrates, thereby improving the sieving effect of the sieve plate 21. Water is injected into the medicine cup 1 and mixed with the crushed medicine. The rotating shaft 31 drives the multiple sets of toothed plates 35 to rotate, thereby increasing the mixing speed of water and medicine.

[0034] Reference Figure 4 , Figure 5 The surface of the cover 12 has a through hole, and a connecting shaft 36 is rotatably connected in the through hole. The bottom surface of the connecting shaft 36 has a positioning groove 37, and the top of the connecting shaft 36 is fixedly connected to a handle 38. The positioning groove 37 on the bottom surface of the connecting shaft 36 is used to mate with the pin 32, so that when the handle 38 rotates, it drives the rotating shaft 31 to rotate.

[0035] Working principle: when using the medicine feeding device, first put the medicine to be mixed into the medicine cup 1, then cover the cover 12. By rotating the handle 38, the connecting shaft 36 rotates, the bottom surface positioning groove 37 is connected with the latch 32, thereby driving the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the fixed shaft 33 and the pressure roller 34 to rotate, the pressure roller 34 crushes the large particle medicine on the surface of the sieve plate 21 into small particles, and the small particles fall into the bottom of the medicine cup 1 through the surface of the sieve plate 21. In the process of rotating the pressure roller 34, the sieve plate 21 is in contact with the convex part 25 on the surface of the sieve plate 21, and the sieve plate 21 will vibrate due to the action of the return spring 24, thereby improving the screening effect.

[0036] When the medicine particles are sufficiently ground and mixed uniformly, water is injected into the medicine cup 1, and the rotation of the rotating shaft 31 also drives the multiple groups of toothed plates 35 to rotate, improving the mixing speed of water and medicine. Through the three-way pipe 11 connected with the nasogastric tube, the medicine is delivered into the patient's body, thereby completing the medicine feeding process.

[0037] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
