[0002] At present, the transfer medicine boxes applied in the ward pharmacy are mostly open plastic boxes and plastic baskets. After being dispensed and audited, the medicines of various departments are loaded into the open transfer medicine box, and then are transferred to the nurse station of each ward by workers. This mode has certain unreasonable aspects. On the one hand, there is a problem of medicine safety. The medicines of various departments often involve multiple types of medicines, such as refrigerated medicines and morphine medicines. During the transfer process, the refrigerated medicines need certain insulation measures, and the morphine medicines need certain control measures. The squeezing problem between scattered injections and large-volume infusion bottles also involves the safety of medicine transfer. In order to solve the above problems, many hospitals increase separate insulation boxes and sealed medicine boxes under limited conditions, and transfer boxes of multiple specifications and sizes are used to meet different needs. However, the overall safety of the transfer of multiple types of medicines is still difficult to solve. On the other hand, there is a problem of verification efficiency. In the original mode, all the medicines of various departments are loaded into the box together, and different types of medicines are mixed together. During the verification process, the nurses need to repeatedly search for the medicines, which reduces the efficiency and increases the risk of medication errors in the compact working environment.

[0060] The drawer assembly 440 includes a plurality of drawers which are sequentially and slidingly nested. Each drawer has a nested state and an expanded state in which the drawers are sequentially exposed. The drawer assembly 440 is arranged at a corner position of the first unit area 4021 in the avoiding position. The drawer assembly 440 is used for placing small and light medicines such as small needle injections and ampoules. Figure 3 When the drawer assembly 440 does not store medicines, the drawer assembly 440 is switched to the nested state (as shown in FIG. 4B). Figure 6 Figure 8 As shown in FIGS. 4C and 4D, the drawer assembly 440 includes three drawers, which are sequentially arranged from the outside to the inside as a first drawer 441, a second drawer 442 and a third drawer 443. The outer contour of the third drawer 443 occupies all the internal space of the second drawer 442, and the outer contour of the second drawer 442 occupies all the internal space of the first drawer 441. Therefore, the carrying capacities of the three drawers are approximately the same. The carrying capacity of one drawer is defined as A, the carrying capacity of n drawers is nA, and the number of medicines to be placed is X.

[0061] When X < A, the third drawer 443 is drawn out, and the medicines are placed in the third drawer 443.

[0062] When A < X < 2A, the second drawer 442 and the third drawer 443 are drawn out, and the medicines are placed in the corresponding drawers.

[0063] When 2A < X < 3A, the second drawer 442 and the third drawer 443 are drawn out, and the medicines are placed in the corresponding drawers.

[0064] In an embodiment, the first unit area 4021 has a rectangular structure. The two adjacent side walls are outwardly convexly provided with support tables 460. The drawer assembly 440 is arranged on the support tables 460 in the use position.

Alternatively, in another embodiment, the limiting mechanism includes a first magnetic member 471 provided on the support table 460, and a second magnetic member 472 provided on the drawer assembly 440 and magnetically attracted to the first magnetic member 471, which is convenient for disassembly. Of course, both limiting mechanisms can be used simultaneously.

[0066] Each drawer is provided with a second magnetic member 472, which is magnetically attracted to the second magnetic member 472 of the adjacent drawer in the storage state to limit the extension of the inner drawer. The first magnetic member 471 is provided in multiple numbers, and part of the first magnetic members 471 are arranged along the extension direction of the drawer and magnetically attracted to the second magnetic member 472 of the corresponding drawer to keep the drawer in the expanded state. The support table 460 is L-shaped, including a first section 461 extending along the sliding direction of the drawer, and a second section 462 perpendicular to one end of the first section 461. In the foregoing, the limiting block 463 protrudes from the second section 462, and part of the first magnetic members 471 are arranged at intervals on the first section 461.

[0067] The aforementioned drawer assembly 440 is located at the corner position of the first unit area 4021 in the avoidance position. As shown in Figure 9 and Figure 10 In an embodiment, the side wall and / or bottom wall of the first unit area 4021 is provided with a third magnetic member 473, which is magnetically attracted to the second magnetic member 472 when the drawer assembly 440 is in the avoidance position to limit the relative movement of the drawer assembly 440.

[0068] Referring to Figure 4 and Figure 5 The first unit area 4021 is slidably provided with a partition plate 480, which is one or multiple in the illustration, and divides the first unit area 4021 into multiple sections. Among them, the two side walls of the first unit area 4021 are provided with a slide rail 490, and the two ends of the partition plate 480 are slidably arranged in the slide rail 490. The slide rail 490 is provided with a sliding groove 491 along the sliding direction, and a plurality of clamping grooves 492 are arranged at intervals and communicate with the sliding groove 491. The two ends of the partition plate 480 are clamped into the clamping grooves 492 to limit the sliding of the partition plate 480.

[0069] As shown in Figure 7 and Figure 9 The bottom of the partition plate 480 is provided with a fourth magnetic member 474, and the bottom of the first unit area 4021 is provided with a fifth magnetic member 475, the number and position of which correspond to the clamping grooves 492, so as to keep the partition plate 480 vertical and prevent it from shaking.
