Description

Technical Field

[0001] This utility model relates to the technical field of laboratory instruments, specifically a rapid pulverizing device for laboratory medicines. Background Technology

[0002] In the microbial limit test of pharmaceuticals, some tablets and small honey pills are difficult to dissolve quickly in diluents due to differences in their manufacturing processes. However, the prerequisite for microbial limit testing of pharmaceuticals is to fully dissolve and mix a certain amount of the drug before conducting bacterial, mold, and yeast counts and control bacteria tests. Traditional methods for dissolving and mixing drugs include shaking in a water bath not exceeding 45°C; however, this method may not fully dissolve some tablets and honey pills within half an hour, while microbial limit tests have strict time requirements (the entire process should not exceed one hour). Another method is to homogenize the drug using a homogenizer, but this method is unsuitable for drugs with a hard texture. Yet another method is to grind the drug in a sterilized mortar with a mortar and pestle, then mix it in a buffer solution; however, this method is time-consuming and labor-intensive, and the residue can easily splatter and contaminate the work surface when forcefully crushing the drug. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model aims to rapidly pulverize hard drugs using a laboratory drug rapid pulverizing device. This prevents hard drugs from being difficult to pulverize, which is time-consuming and laborious. It also avoids the problems of drug residue splashing and contaminating the work surface caused by forceful crushing with a mortar and pestle during sterilization. The pulverizing process is achieved through the following technical solution:

[0004] A rapid pulverizing device for laboratory pharmaceuticals includes a grinding cylinder with a shuttle-shaped grinding chamber inside. A corresponding shuttle-shaped grinding roller is located within the grinding chamber. Partitions are located at both ends of the shuttle-shaped grinding roller. A pressure roller is vertically positioned at the outer center of each partition. Fixed plates are located at both ends of the grinding cylinder. Rollers are located within the fixed plates. An adjusting plate is located inside the rollers. A groove is located on the adjusting plate. The pressure roller extends outward through the groove. A thread is located on the pressure roller in an area close to the groove. A fixed lug is located on the pressure roller.

[0005] Furthermore, a groove is provided on one side of the grinding cylinder, and a feed port is provided at the bottom of the groove to connect to the tail end of the shuttle-shaped grinding chamber. A threaded plug is provided in the feed port.

[0006] Furthermore, the grinding cylinder is divided into two sleeves, left and right, which are connected by internal and external threads.

[0007] Furthermore, the inner wall of the grinding cylinder is smooth or frosted.

[0008] Furthermore, the feed inlet is provided with threads corresponding to the threaded plug.

[0009] Furthermore, the fixed ear seat fixes the relative position of the pressure roller in the chute by the thread on the pressure roller and the adjusting plate.

[0010] Furthermore, the threaded plug is a glass plug.

[0011] The beneficial effects of this utility model are: 1. This utility model can provide a rapid grinding method for laboratory medicines, while avoiding the problem of powder splashing and contaminating the tabletop caused by conventional grinding methods; 2. The position adjustment of the pressure roller provided by this utility model can effectively adjust the distance between the shuttle-shaped grinding roller and the shuttle-shaped grinding chamber, thereby controlling the grinding accuracy to a certain extent.

[0015] 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.

[0016] Combination Figure 1 As shown in the figure:

[0017] A rapid pulverizing device for laboratory pharmaceuticals includes a grinding cylinder 1, a spindle-shaped grinding chamber 2 inside the grinding cylinder 1, a corresponding spindle-shaped grinding roller 3 inside the spindle-shaped grinding chamber 2, partitions 4 at both ends of the spindle-shaped grinding roller 3, and a pressure roller 5 vertically arranged at the outer center of the partitions 4. The spindle structure of this invention is actually a roller structure with conical ends. Fixed plates 6 are provided at both ends of the grinding cylinder 1, and rollers 7 are provided inside the fixed plates 6. Adjusting plates 8 are provided on the inner side of the rollers 7, allowing the rollers to roll. The adjusting plates 8 have grooves 9 for adjustment. The distance between the shuttle-shaped grinding roller 3 and the outer wall of the shuttle-shaped grinding chamber 2 controls the grinding accuracy. The pressure roller 5 extends to the outside through the slide groove 9. The pressure roller 5 has threads in the area close to the slide groove 9. The pressure roller 5 has a fixed ear seat 10. The fixed ear seat 10 fixes the relative position of the pressure roller 5 in the slide groove 9 through the threads on the pressure roller 5 and the adjusting plate 8. The pressure roller 5 is pressed down by both hands, and at the same time the grinding cylinder rolls on the table. At this time, the shuttle-shaped grinding roller 3 remains relatively stationary due to the relative rolling of the adjusting plate 8. The relative rolling of the grinding cylinder 1 grinds the drug.

[0018] The grinding cylinder 1 has a groove 11 on one side. The bottom of the groove 11 has a feed inlet 12 that connects to the tail end of the shuttle-shaped grinding chamber 2. The feed inlet 12 has a threaded plug 13. The diameter of the groove 11 is larger than the diameter of the threaded plug 13, which facilitates the disassembly of the threaded plug 13 and is used for internal sealing.

[0019] The grinding cylinder 1 is divided into two sleeves, left and right, which are connected by internal and external threads, making it easy to connect and separate the grinding cylinder.

[0020] The inner wall of the grinding cylinder 1 is either smooth or frosted, and different degrees of smoothness can be selected according to actual needs.

[0021] The feed inlet 12 is provided with a thread corresponding to the threaded plug 13.

[0022] The threaded plug 13 is a glass plug, which effectively ensures the overall sealing and prevents powder leakage.

[0023] Working principle: When grinding is required, remove the threaded plug and feed the material through the inlet. Then, replace the threaded plug to seal the cylinder. Press down on the pressure roller with both hands to make the grinding cylinder roll on the table. At this time, the adjusting plate rotates within the roller shaft. While the grinding cylinder rolls, the shuttle-shaped grinding roller remains stable, allowing the material to be ground under force between them. The position of the pressure roller in the chute is fixed by the threads on the fixing lug and the pressure roller, controlling the distance between the shuttle-shaped grinding roller and the outer wall of the grinding chamber, as well as the smoothness of the outer wall of the grinding chamber (smooth or abrasive), thus allowing for a certain degree of adjustment of the grinding precision. After grinding, the grinding cylinder is separated into two sleeves by the internal and external threads in the middle, allowing the medicine to be removed.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
