Not only are the tablets ground more finely, but the tablets will not bounce around in the grinding cylinder, and the dosage of the medicine used will be more accurate.

Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a tablet grinder. Background Art

[0002] Tablet drugs are one of the most commonly used oral dosage forms in clinical medical treatment. They are easy to package, carry, store and take. Normal people usually take them directly with water. However, when encountering patients who are unconscious or in a coma, it is usually necessary to grind the tablets into powder, mix the powder with liquid and then feed the patient through the nose. Existing tablet grinders have particles in the powder after grinding, which is easy to block the nasogastric tube when feeding the patient through the nasogastric tube. Summary of the invention

[0003] The object of the present invention is to provide a tablet grinder to address the above-mentioned defects in the prior art.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A tablet grinder comprises a grinding head and a grinding cylinder. The grinding head comprises a grinding piece and an extrusion piece. The grinding piece is composed of an upper vertical rod and a lower flat plate-shaped base plate connected to each other. The extrusion piece is a structure with openings at both ends and a hollow interior. The vertical rod can rotatably pass through the extrusion piece and be connected to a motor. A plurality of first grinding teeth are arranged on the bottom surface of the base plate. The grinding cylinder is a structure with an opening facing upward and a hollow interior and a sieve hole is arranged on the bottom. Second grinding teeth cooperating with the first grinding teeth are arranged on the inner bottom surface of the grinding cylinder. The extrusion piece is threadedly connected to the grinding cylinder.

[0006] As a further improvement of the above technical solution:

[0007] The plurality of first grinding teeth are evenly distributed along a plurality of radii with the center of the substrate as the center, and the plurality of second grinding teeth are evenly distributed along a plurality of radii with the center of the bottom surface of the grinding cylinder as the center. The number of radii of the substrate is the same as the number of radii of the bottom surface of the grinding cylinder, and the difference in radius between the substrate and the bottom surface of the grinding cylinder with the same number of radii is 3-8 mm. The first grinding teeth can better cooperate with the second grinding teeth. When the first grinding teeth are relative to the second grinding teeth, the tablets between the first grinding teeth and the second grinding teeth can be ground and cut more delicately.

[0008] In order to achieve the purpose of detachable cleaning of the grinding cylinder, the grinding cylinder includes a cylinder body and a bottom plate installed in the cylinder body, at least two limit heads are provided on the inner wall of the bottom of the cylinder body, the limit heads are blocked under the bottom plate, and the gap between the two limit heads is connected to the sieve holes; the extrusion piece is inserted into the cylinder body and is threadedly connected to the cylinder body, and the second grinding teeth are arranged on the upper surface of the bottom plate.

[0009] The volume of the grinding cylinder is 300 mL, which is convenient for storage and use.

[0010] The motor is connected to a rechargeable battery. A handle is provided on the top of the extrusion piece for easy use by the operator.

[0011] The bottom of the grinding cylinder is threadedly connected with a medicine powder box.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] The tablet grinder utilizes the rotation of the extruder relative to the grinding cylinder to crush the tablets between the grinding member and the grinding cylinder under pressure. The grinding member rotates during the pressure crushing to cut and grind the tablets. Not only are the tablets ground more finely, but the tablets will not bounce around in the grinding cylinder, and the dosage of the medicine used will be more accurate.

[0018] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 and Figure 2As shown, the tablet grinder of this embodiment includes a grinding head and a grinding cylinder 5. The grinding head includes a grinding piece 4 and an extrusion piece 3. The grinding piece 4 is composed of an upper vertical rod 41 and a lower flat plate-shaped base plate 42. The extrusion piece 3 is a hollow structure with openings at both ends. The vertical rod 41 can be rotatably passed through the extrusion piece 3 and connected to the motor 1. A plurality of first grinding teeth 43 are provided on the bottom surface of the base plate 42. The grinding cylinder 5 is a hollow structure with an opening facing upward and a sieve hole 53 is provided on the bottom. The inner bottom surface of the grinding cylinder 5 is provided with second grinding teeth 54 that cooperate with the first grinding teeth 43. The base plate 42 extends out of the extrusion piece 3 and is inserted into the grinding cylinder 5. The extrusion piece 3 is threadedly connected to the grinding cylinder 5. The plurality of first grinding teeth 43 are evenly distributed along a plurality of radii with the center of the base plate 42 as the center, and the plurality of second grinding teeth 54 are evenly distributed along a plurality of radii with the center of the bottom surface of the grinding cylinder 5 as the center. The radius of the substrate 42 is the same as the radius of the bottom surface of the grinding cylinder 5, and the radius difference between the same radius of the substrate 42 and the bottom surface of the grinding cylinder 5 is 3-8 mm.

[0020] Among them, the grinding cylinder 5 includes a cylinder 51 and a bottom plate 52 installed in the cylinder 51, at least two limit heads 55 are provided on the inner wall of the bottom of the cylinder 51, the limit heads 55 are blocked below the bottom plate 52, and the gap between the two limit heads 55 is connected to the sieve hole 53; the extrusion piece 3 is inserted into the cylinder 51 and threadedly connected to the cylinder 51, and the second grinding teeth 54 are arranged on the upper surface of the bottom plate 52. The volume of the grinding cylinder 5 is 300ML. The motor 1 is connected to a rechargeable battery. A handle 2 is provided on the top of the extrusion piece 3. A powder box 6 is threadedly connected to the bottom of the grinding cylinder 5.
