Description

Technical Field

[0001] The utility model belongs to the technical field of medicine dispensing equipment, and in particular relates to a high-efficiency medicine cutting device used in a hospital pharmacy. Background Art

[0002] Tablets refer to sheet preparations formed by evenly mixing drugs and excipients and compressing them. Tablets are a commonly used drug dosage form in hospitals. Tablets are easy to carry and can effectively treat diseases. However, some tablets in hospitals are larger in size, and patients have individual differences in medication. For some patients, they do not need a large dose of medicine. Doctors may prescribe half a tablet, one third or one quarter tablet according to the patient's specific situation. Pharmacies need to cut the tablets into pieces to meet specific medication needs. Therefore, these tablets need to be split.

[0003] Tablet cutting uses special tools, such as tablet cutters or clean blades, to split the tablets one by one. However, the current tablet splitting devices generally only split single tablets, and a device can only split a single tablet, such as half a tablet, a quarter tablet, etc., which causes pharmacists working in hospital pharmacies to face heavy slicing work every day. Using blades to split is undoubtedly inaccurate and cannot meet the slicing needs of hospital pharmacies; secondly, it is only for single-tablet splitting and cannot be used for batch splitting of tablets, which is undoubtedly inefficient; thirdly, it is impossible to split tablets of different sizes and specifications at the same time, which still affects efficiency. The tablet splitting devices currently on the market are only suitable for individual patients and are not suitable for large-scale slicing in hospital pharmacies. Therefore, an efficient medicine cutting device for hospital pharmacies is needed to solve the above technical problems. Utility Model Content

[0041] Example 3

[0042] In this embodiment, a limit strip 41 is fixedly provided parallel to the upper end of the double-part chassis 4, a square groove 411 is provided on the upper part of the limit strip 41, and a limit plate 46 is detachably installed on the square groove 411. The limit strip 41 of the chassis is made of hard plastic or sterile hard silicone material, and has sufficient strength and wear resistance; limit blocks 421 are fixedly provided on both outer sides of the limit strip 41, and a slide groove 42 is provided corresponding to the lower end of the limit block 421, and a spring 32 is installed on the slide groove 42. Through the elastic action of the spring 32, the limit strip 41 can move up and down within a certain range. The spring 32 is connected to the limit block 421, and the upper ends of the limit block 421 are fixed by butterfly nuts 422. The movement of the limit bar 41 is controlled by controlling the tightness of the butterfly nuts 422 to adjust the size of the space for clamping the tablets. A square groove 411 is provided on the upper part of the limit bar 41. The size of the square groove 411 matches the size of the limit plate to ensure that the limit plate does not slip during the sliding clamping process. A limit plate 46 is detachably mounted on the square groove 411. The limit plate 46 is made of the same hard plastic material as the limit bar 41. The limit plate 46 is a retractable U-shaped structure, which can be easily inserted into and removed from the square groove 411. One side of the limit strip 41 is open for inserting the limit plate 46, and a handle 43 is fixedly provided on the right side of the double-part chassis 4; the handle 43 is provided to facilitate taking out the entire double-part chassis 4; at the same time, in order to ensure that the two-part cutting knife can smoothly cut to the center of different tablets when using the butterfly bolt, an indicator line is provided between the limit strips, and the indicator line can accurately divide the tablet into two parts;

[0043] In addition, in the present embodiment, the limiting plate 46 is a retractable U-shaped structure, and one side of the limiting plate 46 is a raised wedge-shaped head 47, and the wedge-shaped head 47 is hollow; the tablets can be quickly filled through the limiting plate 46, and the tablets can be directly placed on the wedge-shaped head 47 during filling. In order to ensure that the tablets can enter and will not stand up, it is necessary to ensure that the distance between the limiting plate 46 and the limiting strip 41 is smaller than the diameter of the tablet.

[0044] Example 4

[0045] In this embodiment, a plurality of tablets can be placed by setting a multi-part chassis 5, and the multi-part chassis 5 includes a support plate 51 and a pressure plate 52; one side of the pressure plate 52 is detachably mounted with a support plate 51 by bolts, and a plurality of adjustment rods 511 are fixedly arranged in a linear array on the inner side of the support plate 51, and a plurality of push plates 512 are arranged at intervals on the adjustment rods 511; a plurality of circular grooves 53 are arranged in an array on the upper end of the pressure plate 52, and an arc groove 54 is arranged on the inner side wall of the circular groove 53 corresponding to the disassembly side of the support plate 51; the position of the push plate 512 on the circular groove 53 is adjusted by controlling the left and right sliding of the support plate 51 to adjust the clamping position of the circular groove 53 Holding tablets; specifically, when the tablets need to be divided into three or four equal parts, the tablets are placed on the pressure plate 52 and then shaken left and right or directly pushed into the circular groove 53 by hand; before pushing in, the position of the support plate 51 can be further adjusted by sliding left and right, and the position of the push rod set on the support plate 51 is adapted to the position of the circular groove 53, and the tablets are clamped by the position of the push plate 512 on the arc groove 54. After the adjustment is completed, the tablets can be placed to ensure that the placed tablets can completely fall into the circular groove 53 under the action of shaking. At the same time, when the support plate 51 is moved, it can be fixed by bolts.

[0046] In addition, in this embodiment, in order to ensure that the process can be fully realized, the spacing distance of the push plate 512 is equal to the spacing distance of the arc groove 54 opened on the inner wall of the circular groove 53; at the same time, the push plate 512 is an arc-shaped structure that can fit the arc groove 54; in addition, in order to ensure that the three-segment knife group 36 and the four-segment knife group 37 will not directly cut the push plate 512 during segmentation, the size of the push plate 512 is limited to the interval between the three-segment knife 361 and the four-segment knife 371, as shown in the figure. Fig.14 , Fig.15 As shown, it can be fully ensured that when the medicine is divided, pressing the three-part dividing blade 351 and the four-part dividing blade 351 of the pressing mechanism 3 will not produce a cutting effect on the push plate 512.

[0047] Example 5

[0048] In this embodiment, another multi-part bottom plate for holding tablets is provided, specifically as follows Fig.16As shown, the upper end array of the specific pressure plate 52 is provided with a plurality of clamping mechanisms, and the clamping mechanisms include a fixed block 55 arranged in a single circular array, an elastic block 56 is arranged on the inner side of the fixed block, and a clamping block 57 is fixedly arranged at the end of the elastic block 56; when in use, the tablets are directly inserted between the clamping blocks, and the tablets can be clamped under the action of the elastic block 56. At the same time, because it is arranged in a circular array, tablets of different sizes can be clamped when clamping the tablets, and the center clamping can be achieved, so that when using a three-cutting knife and a four-cutting knife for cutting, the effect of equal division can be achieved, and the cutting form between the clamping blocks can adapt to the three-cutting knife and the four-cutting knife; compared with Example 4, the advantage is that tablets of different models can be clamped, while in Example 4, only specific sizes can be clamped, otherwise it will be non-centering, resulting in the inability to divide them evenly. It is a preferred embodiment in the present application.

[0049] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described.
