Description

Technical Field

[0001] The utility model belongs to the technical field of tablet grinding, in particular to a grinding device for clinical nasogastric tablets. Background Art

[0002] In medical nasogastric feeding clinics, when patients cannot take the tablets directly, they need to grind the tablets into powder and then take them through nasogastric feeding.

[0003] When grinding existing tablets, medical staff or patient caregivers usually use glass bottles or other tools to roll and grind them. The powder ground in this way is not uniform enough and there will be large particles. Not only is the operation complicated and easy to cause the medicine to fall, but it also affects the patient's absorption of the medicine. At the same time, the large particles will also cause a certain impact when eating. Therefore, we proposed a grinding device for clinical nasogastric tablets. Utility Model Content

[0034] A specific application of this embodiment is:

[0035] When in use, the transparent protective cover 121 is rotated counterclockwise to make it leave the rotating ring 12, and the top of the shell 1 can be opened. Then, the tablets to be ground are put into the grinding box 11 from the top, and the tablets fall on the grinding roller 131. Then, the transparent protective cover 121 is threadedly connected with the threaded ring 122, and the transparent protective cover 121 is rotated clockwise to be installed on the rotating ring 12, which can prevent the medicine from falling and facilitate the observation of the internal situation of the grinding box 11. Then, the rotating ring 2 is rotated to drive the fixed shaft 32 to rotate through the connecting rod 34, and the fixed shaft 32 drives the turntable 31 to move in the limit ring 3 The rotating ring 12 is rotated to make the drug discharge hole 114 on the rotating disk 31 not communicate with the drug discharge hole 114 on the fixed plate 113, so that the bottom of the grinding box 11 is sealed, and then the rotating ring 12 is rotated, and the rotating ring 12 drives the rotating rod 132 to rotate through the connecting frame 123, and the rotating rod 132 drives the grinding roller 131 to rotate. Since the top of the grinding roller 131 is conical, the medicine will be guided to move to the gap between the grinding roller 131 and the grinding box 11. The continuous rotation of the grinding roller 131 will grind the tablets, and the ground medicine powder will pass through the filter plate 111. The tablets are discharged from the filter plate 111 through the groove and then fall onto the fixed plate 113. Since the filter plate 111 is provided with a leakage groove, the ground tablets will not be discharged from the filter plate 111 when they are large, and will be continuously ground until they are smoothly discharged from the filter plate 111, which can make the grinding more uniform and avoid the situation of large particles. At the same time, during the grinding process, the arc block 133 on the inner wall of the grinding roller 131 will contact with the spherical block 142. When the two come into contact, they will collide, thereby having a vibration effect, which can vibrate and discharge the powder attached to the outer surface of the grinding roller 131 and the inner wall of the grinding box 11, reducing the residue. After the spherical block 142 contacts the arc block 133, it will be pushed, thereby driving the telescopic rod 141 to slide in the collision seat 14 and stretching the spring 143. When the spherical block 142 leaves the arc block 133, the telescopic rod 141 drives the spherical block 142 to reset under the elastic action of the spring 143. This reciprocating process can continuously vibrate during the grinding process to improve the unloading rate. Finally, after the grinding is completed, the rotating ring 2 drives the turntable 31 to rotate, so that the turntable 31 and the medicine discharge hole 114 on the fixed plate 113 are connected to each other, and the ground medicine powder can be discharged, and the operation is more convenient and quick.
