[0034] This invention provides a solid drug grinding and dissolving apparatus, comprising a container, a grinding core, a rotary drive mechanism, a scraping component, a syringe interface, and a sealing element. The grinding core is inserted into the top of the container, and the two are threadedly connected. The rotary drive mechanism drives the grinding core to rotate relative to the container, achieving rotation and axial movement of the grinding core, forming a powder chamber between the grinding core and the container. In use, solid drugs are loaded into the powder chamber, and the rotary drive mechanism drives the grinding core to rotate and compress the space in the powder chamber, crushing the solid drugs into powder. After grinding, the scraping component removes the powder adhering to the grinding core and the container. Then, the sealing element is opened to expose the syringe interface. The syringe is connected to the syringe interface, solvent is injected, and after the solvent dissolves the powder, the syringe withdraws the liquid. This invention ensures that the drug remains within the sealed powder chamber during the grinding process, preventing drug splashing or the introduction of environmental microorganisms.

[0035] The following is combined with Figures 1 to 4 This invention describes a solid drug grinding and dissolving apparatus.

[0036] An embodiment of this utility model provides a solid drug grinding and dissolving device, including a container 100, a grinding core, a rotary drive mechanism, a scraping component, a syringe interface 400, and a sealing component 500.

[0037] The container 100 can be a cylindrical body with an open top and internal threads provided on the inner wall of the container 100.

[0038] The outer circumferential surface of the grinding core is provided with external threads. The grinding core is placed inside the container 100 and is threadedly connected to the container 100. A powder hopper 600 is formed between the bottom of the grinding core and the inner bottom of the container 100.

[0039] The rotary drive mechanism is connected to the grinding core drive and is used to drive the grinding core to rotate inside the container 100, and the rotation axis is coaxial with the container 100.

[0040] The scraping assembly includes a scraper 810 and a rotating rod 820. A shaft hole is provided at the center of the grinding core, and the shaft hole is collinear with the axis of the grinding core and penetrates through the grinding core. A receiving groove 900 is provided on the bottom surface of the grinding core. The receiving groove 900 extends upward from the bottom surface of the grinding core and extends radially from the shaft hole towards the outer peripheral surface of the grinding core, ultimately forming a cuboid-shaped receiving groove 900.

[0041] The rotating rod 820 is rotatably inserted into the shaft hole, and the rotating rod 820 can slide along the axial direction of the shaft hole. One end of the scraper 810 is connected to the bottom end of the rotating rod 820, and the other end of the scraper 810 extends radially along the grinding core.

[0042] The rotating rod 820 can move the scraper 810 to the first, second, and third positions. When the scraper 810 is in the first position, it is fully inserted into the receiving groove 900, and its bottom surface is flush with the bottom surface of the grinding core. At this time, grinding can be performed. After grinding, the scraper 810 can be moved to the second position, where its top surface is flush with the bottom surface of the grinding core. At this time, when the rotating rod 820 rotates the scraper 810, its top surface can scrape off the powder adhering to the bottom surface of the grinding core. Then, the scraper 810 can be moved to the third position, where its bottom surface is in contact with the inner bottom surface of the container. At this time, when the rotating rod 820 rotates the scraper 810, its bottom surface can scrape off the powder adhering to the bottom surface of the container.

[0043] A syringe port 400 is disposed on the container 100 or the grinding core. The syringe port 400 connects the inner and outer sides of the powder chamber 600. The syringe port 400 is used to connect to a syringe to inject solvent into the powder chamber 600 and to extract the dissolved powder from the powder chamber 600. A sealing element 500 is used to detachably connect to the syringe port 400 to achieve the effect of sealing or opening the syringe port 400.

[0044] In use, medical personnel can rotate the grinding core out of the container 100 using the rotary drive mechanism, and then place the solid medication into the container 100. The grinding core is then rotated back into the container 100 using the rotary drive mechanism. At this point, the scraper 810 moves to the first position, i.e., the scraper 810 is located within the receiving groove 900, to prevent the scraper 810 from restricting the downward movement of the grinding core. During rotation, the solid medication is ground and pulverized. Simultaneously, driven by the thread, the grinding core continues to move downwards, providing downward pressure for the pulverization of the solid medication, further accelerating the pulverization process. During the grinding process, the sealing element 500 needs to remain connected to the syringe interface 400.

[0045] After grinding is complete, the grinding core is first rotated in the reverse direction so that the height of the powder hopper is sufficient to accommodate the scraper 810, that is, the distance between the bottom surface of the grinding core and the inner bottom surface of the container is greater than the height of the scraper 810. At this time, the scraper 810 is moved to the second position by rotating the rod 820 to scrape off the powder adhering to the bottom surface of the grinding core. Then, the scraper 810 is moved to the third position by rotating the rod 820 to scrape off the powder adhering to the inner bottom surface of the container 100.

[0046] After all the powder has been scraped off, remove the sealing component 500 from the syringe port 400, connect the syringe containing the solvent to the syringe port 400, and then inject the solvent into the powder container 600. After the powder in the powder container 600 has completely dissolved, use the syringe to extract the liquid from the powder container 600, and then reconnect the sealing component 500 to the syringe port 400.

[0047] It should be noted that after pulverization, the grinding core can be rotated in the reverse direction first, so that the height of the powder hopper is sufficient to accommodate the scraper 810. Then, the rotating rod 820 drives the scraper 810 to move between the bottom surface of the grinding core and the inner bottom surface of the container. Subsequently, the scraper 810 is rotated to avoid the position of the receiving groove 900. Then, the grinding core is rotated again to move it downwards until the top surface of the scraper 810 is in contact with the bottom surface of the grinding core, and at the same time, the bottom surface of the scraper 810 is in contact with the inner bottom surface of the container 100. At this time, when the scraper 810 is rotated, it can simultaneously scrape off the powder on the bottom surface of the grinding core and the inner bottom surface of the container 100, improving the scraping efficiency.

[0048] The solid drug grinder and dissolver provided by this utility model can grind and pulverize drugs in the enclosed space of the powder chamber 600 without causing drug splashing or introducing environmental microorganisms during the grinding process.

[0049] In some embodiments, abrasive particles 700 may be disposed on the inner bottom of the container 100, or on the bottom surface of the grinding core, or simultaneously disposed on both the inner bottom of the container 100 and the bottom surface of the grinding core. During the rotation of the grinding core, the abrasive particles 700 can reduce the contact area with the solid drug, thereby increasing the local stress on the solid drug and further accelerating the grinding efficiency.

[0050] In some embodiments, the container 100 can be a cylindrical body with an open top, and its material can be transparent. This facilitates observation of the state of the solid drug, allows for a more intuitive judgment of whether the grinding has met the required standards, and also facilitates observation of the dissolution of the drug powder after the solvent is injected. For example, the container 100 can be made of medical glass.

[0051] In some embodiments, the grinding core can be a grinding disc 210, which is threadedly connected to the container 100. A syringe interface 400 can be disposed on the grinding disc 210 and extends through it along its axial direction. The rotary drive mechanism includes a rotating handle 300, which is eccentrically disposed on the top of the grinding disc 210, and the axis of the rotating handle 300 can be parallel to the axis of the grinding disc 210.

[0052] Alternatively, the grinding core can be a grinding column 220, the axial length of which can be greater than the depth of the container 100. Since the axial length of the grinding column 220 is relatively long, placing the syringe interface 400 on the grinding column 220 would result in an excessively long channel distance. Therefore, the syringe interface 400 can be placed on the container 100, for example, on the side or bottom of the powder storage compartment 600. The rotary drive mechanism can be the same as that in the previous embodiment, or the portion of the grinding column 220 extending beyond the container 100 can be used as the rotary drive mechanism.

[0053] In some embodiments, the sealing element 500 may be a rubber stopper.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
