However, there are some problems with traditional nasogastric administration, such as the excessive size of the medicine particles may cause poor or blocked administration, and the medicine dosage is difficult to control during administration. Although the existing medicine cutting and grinding nasogastric propulsion devices on the market have facilitated medical workers and patients to a certain extent, there are still some shortcomings. For example, the Chinese utility model patent with authorization announcement number CN215386039U discloses a nasogastric medicine dispenser with a grinder, wherein a push rod is installed on one side of the main support, a grinding rod is installed on the inside of the push rod, a grinding head is installed on one end of the grinding rod, and a fast-crushing tooth pattern is provided on the outside of the grinding head, a liquid-pushing rubber block is installed on one end of the push rod, the liquid-pushing rubber block is fixedly connected to the push rod, and the liquid-pushing rubber block is connected to the grinding rod by a slot, and a medicine cover is installed on one side of the upper end of the main support, and the medicine cover is connected to the main support by a hinge. However, when faced with large-particle drugs, the device cannot cut the drugs first and then grind them, resulting in a slow grinding speed and low efficiency. In addition, during the grinding process, the grinding particles are very likely to stick to the grinding head and the inner wall of the syringe, causing the needle to be clogged.

DETAILED DESCRIPTION
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0022] Embodiment: A medicine cutting and grinding nasogastric feeding propulsion device, comprising: Figure 1-4 As shown, the syringe includes a push rod 1 and a tube body 2. Combined with the syringe structure, it is arranged at the upper end of the syringe. The ground drug particles can automatically fall into the nasogastric tube, avoiding the blockage of the needle by the drug particles, making the drug advancement process smoother, easier to operate, and improving work efficiency. Figure 1 As shown, a connecting tube 3 is provided on the upper side of the tail end of the tube body 2, and the connecting tube 3 is funnel-shaped. The connecting tube 3 presents a funnel-shaped shape, which helps the ground powder to flow into the tube body 2. A grinding box 5 is provided on the connecting tube 3 and communicates with the tube body 2. The inner wall of the grinding box 5 is provided with a serrated groove 6. Figure 2-3 As shown, the grinding box 5 mainly includes a grinding base 11 and a top cover 12. These two parts are tightly connected together by a threaded connection to ensure the stability and safety of the grinding box 5 during use. Figure 4As shown, the lower surface of the grinding base 11 is provided with a through hole 17 and four fan-shaped grooves 18 arranged around the through hole 17, and a serrated groove 6 is provided on the inner wall of the grinding base 11. The provision of these serrated grooves 6 enables the grinding box 5 to better fix and grind the material during the grinding process, thereby improving the grinding efficiency. A grinding rod 7 is provided in the grinding box 5, and the grinding rod 7 rotates in conjunction with the grinding box 5, so that the grinding process can proceed smoothly. A grinding head 8 is provided on the grinding rod 7, and a spiral groove 9 and four cutting edges 10 are provided on the grinding head 8. These spiral grooves 9 and cutting edges 10 can effectively crush and refine the material during the cutting and grinding process of the medicine, thereby improving the grinding effect and enabling the medicine to be effectively ground into fine particles or powder. As shown in the attached Figure 2 As shown, the bottom of the grinding head 8 is conical, the spiral groove 9 is provided on the curved surface of the grinding head 8, and the cutting edge 10 is provided on the upper end of the grinding head 8. The radius of the bottom surface of the grinding head 8 is close to the inner wall of the grinding box 5, so that the grinding is more uniform. A sliding cover 13 is provided on the grinding rod 7, and the sliding cover 13 rotates with the grinding rod 7. An arc groove 14 is provided on the upper side of the top cover 12, and a sliding rod 15 is provided on the upper side of the sliding cover 13. The sliding rod 15 is slidably provided in the arc groove 14, so that the user can put the medicine into the grinding box 5 from the arc groove 14, and can better prevent dust from contaminating the medicine liquid. As shown in the attached Figure 3 As shown, the grinding rod 7 is provided with a limiting ring 16 located below the sliding cover 13, and the limiting ring 16 abuts against the sliding cover 13, thereby limiting the sliding cover 13. The grinding head 8 is arranged below the limiting ring 16, and one end of the grinding rod 7 is passed through and fixed in the through hole 17. Preferably, the other end of the grinding rod 7 is connected to a threaded handle 4 through the top cover 12. The design of the threaded handle 4 enables the user to easily rotate the grinding rod 7, thereby controlling the grinding process, making the grinding process safer and avoiding possible injuries caused by manual grinding. Through the medicine cutting and grinding nasogastric feeding propulsion device, the medicine can be quickly cut and ground, and directly propelled through the nasogastric feeding through a syringe, which greatly simplifies the steps of medicine processing and feeding and improves the convenience of use.
[0023] Working process
[0024] First, prepare the medicine that needs to be ground and pull the push rod 1 of the syringe to the rear end of the opening of the connecting tube 3. Then, the push rod 1 rotates the slide bar 15 to move the slide cover 13, and the medicine is placed in the grinding box 5 through the arc groove 14. At the same time, the slide cover 13 can also effectively prevent dust from contaminating the liquid medicine. By rotating the threaded handle 4, the grinding rod 7 is rotated in the grinding box 5, and the spiral groove 9 and cutting edge 10 on the grinding head 8 are used to cut and grind the medicine. When the medicine is ground to the required particle size, the ground medicine is allowed to fall into the tube body 2 of the syringe through the connecting tube 3. Use the push rod 1 of the syringe to absorb liquid and mix it with the ground medicine, and then push the liquid medicine into the patient's stomach through the nasogastric tube. After use, clean the grinding box 5, syringe and nasogastric tube in time to prevent drug residue and bacterial growth.
[0025] In summary, the utility model has a simple structure, can achieve efficient grinding and cutting of medicines, and avoid the problem of drug particle blockage.
