Description

Technical Field

[0001] The invention relates to the technical field of anesthetic drug preparation, in particular to a tablet grinding device for anesthetic drug preparation. Background Art

[0002] As we all know, general anesthesia is required before most surgeries. The anesthesiologist will prepare the anesthetic drugs. In most cases, multiple drugs need to be mixed and prepared. Anesthetic drugs are available in liquid, powder and tablet forms. When preparing mixed anesthetic drugs for different patients, tablets and liquid drugs will be mixed. Before mixing, the tablet drugs usually need to be crushed and then mixed with the liquid drugs.

[0003] At present, the mortars and tablet grinders commonly used in the process of grinding tablets are both manually pressed. Since the tablets are extruded and have a certain hardness, they need to be crushed with force before each grinding. If too much force is used, the tablets will bounce away. In addition, manual grinding takes a long time, and the powder ground out is uneven in coarseness and is not easy to dissolve in water.

[0004] Existing tablet grinders, such as the tablet grinder disclosed in Publication (Announcement) No.: CN205286962U, require the tablets to be crushed during the grinding process. During the crushing process, the user needs to operate with both hands at the same time. During the operation, the device moves with the movement of the user's hands, which will affect the user's normal force. At the same time, when the tablets are crushed for the first time, the user needs to use a lot of force to crush them, which is time-consuming and labor-intensive. Summary of the invention

The pushing block 704 drives the knocking plate 702 to move during the movement, and the knocking plate 702 knocks the transmission plate 708 fixed on the filter frame 607, so that the vibration generated by the knocking is transmitted to the filter frame 607, and the knocking speed of the powder is accelerated by the knocking, and at the same time, the powder is prevented from being blocked in the filter frame 607. The powder is collected by the medicine box 2, and the medicine box 2 is removed from the cylinder 1. The user can mix the powder in the medicine box 2 with warm water or other liquids for children to take.
