Description

Technical Field

[0001] This invention belongs to the field of ambulance technology, specifically relating to a convenient first-in-first-out medicine drawer and a method for replenishing medicines. Background Technology

[0002] An emergency cart is an essential piece of emergency medical equipment in hospital departments, providing great convenience for patient resuscitation in emergency situations. An emergency cart typically consists of an emergency work surface, drawers, cabinets, a waste bin, and casters. The drawers and cabinets contain essential medications and resuscitation equipment.

[0003] Current medical regulations require that medicines in drawers must be processed in a first-in, first-out (FIFO) manner, and drawers are required to facilitate this FIFO process. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to design a medicine box drawer that facilitates first-in, first-out (FIFO) operation.

[0005] The specific technical solution of the present invention is as follows: A convenient first-in-first-out (FIFO) medicine drawer includes a drawer frame. In the right-left direction, the space inside the drawer frame is divided into at least one column of cells. In the front-back direction, the space inside each column of cells is divided into at least two layers of medicine storage strips. Each layer of medicine storage strips holds one type of medicine. Multiple medicine units are fixed in each layer of medicine storage strips, and each medicine unit holds one medicine. A partition is provided between two adjacent medicine units. A rotating shaft is fixed on the partition and is rotatably connected to the medicine storage strip. A return spring is provided between the upper part of the partition and the medicine storage strip. When there is no other external force, the partition is in a vertical position under the action of the return spring.

[0006] The lower part of the partition is a partition section, which is wider at the top and narrower at the bottom; one side of the upper part of the partition is a rotation space, and the other side is a blocking block, which is fixed to the medicine storage bar.

[0007] The medicine is sandwiched between two adjacent storage strips, specifically: The medicine storage bar includes a medicine storage bar sloping plate, the bottom of which is fixed to the medicine storage bar sloping plate. The medicine storage bar can slide on the drawer bottom plate of the drawer frame. A horizontal post is fixed to the innermost medicine storage bar, and the horizontal post passes through the through hole in the inner end plate of the drawer frame. A compression spring is sleeved on the horizontal post between the innermost medicine storage bar and the inner end plate of the drawer. The two ends of the compression spring contact the innermost medicine storage bar and the inner end plate of the drawer, respectively. By the compression of the compression spring, all the medicine storage bars are connected and fixed together as one unit.

[0008] The medicine storage horizontal plate is U-shaped, and its vertical plate has mounting holes or alignment holes. The mounting holes are connected to positioning posts. At two adjacent medicine storage horizontal plates, one vertical plate has an alignment hole and the other vertical plate has a positioning post. The positioning post extends into the alignment hole.

[0009] The storage tray for small medicines is a standard tray, while the storage tray for large medicines is a combination of a standard tray and an adjustment tray.

[0010] The drug unit includes a drug unit inclined plate with multiple rows of first screw holes and a drug storage horizontal bar inclined plate with multiple rows of second screw holes. Both the first and second screw holes are threadedly connected to fastening bolts. By tightening the fastening bolts, the drug unit inclined plate and the drug storage horizontal bar inclined plate are fixed together.

[0011] The drug unit is tilted, and the angle between it and the horizontal column is acute.

[0012] A method for replenishing medicines, using the aforementioned convenient first-in-first-out medicine drawer, includes the following steps: S20. Open the drawer; S21. With one hand, move the leftmost medicine on the medicine storage bar to the right until the originally empty medicine unit is "occupied" by the moved medicine. During the movement of the drug unit, the drug unit squeezes the partition, causing the partition to rotate along the axis of rotation. The partition cannot stop the movement of the drug unit. After the medicine unit passes the partition, the partition returns to a vertical position under the action of the return spring. S22. At this point, the leftmost medicine unit becomes empty. Manually add new medicine to this empty space. S23. Close the drawer.

[0013] Compared with the prior art, the technical advantage of the present invention is that the partition of the present invention is provided with a rotating shaft, which facilitates the overall adjustment of the position of the medicine and facilitates the "first-in, first-out" operation.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 5 A convenient first-in-first-out medicine drawer includes a drawer frame 100. In the right-left direction, the space inside the drawer frame 100 is divided into at least one column (four columns in the figure) of cells 110. In the front-back direction, the space inside each column of cells 110 is divided into at least two layers of medicine storage strips 120. Each layer of medicine storage strips 120 holds one type of medicine 900. Multiple medicine units 300 are fixed in each layer of medicine storage strips 120. Each medicine unit 300 holds one medicine 900, which can be a large medicine 901 or a small medicine 902.

[0026] like Figure 6-8 A partition 400 is provided between two adjacent medicine units 300. A rotating shaft 410 is fixed on the partition 400. The rotating shaft 410 is rotatably connected to the medicine storage bar 120. A return spring (not shown in the figure) is provided between the upper part 420 of the partition 400 and the medicine storage bar 120. When there is no other external force, the partition 400 is in a vertical state under the action of the return spring.

[0027] like Figure 10 In order to implement the first-in-first-out principle, one side of the upper part 420 of the partition 400 is a rotation space 341, and the other side is a blocking block 340, which is fixed on the medicine storage bar 120.

[0028] Thus, when the partition 400 is in a vertical position, the partition 400 can only rotate in one direction. See Appendix. Figure 10 Arrow A is pointing in the direction of the arrow.

[0029] In order to reduce the impact on the medicine 900, the lower part of the partition 400 is a partition 403, which is wider at the top and narrower at the bottom.

[0030] To facilitate the replacement of the position and order of medicine 901 and small medicine 902, the following improvements are made: like Figure 1-5 The medicine storage bar 120 includes a medicine storage bar inclined plate 210. A medicine storage bar 200 is fixed to the bottom of the medicine storage bar inclined plate 210. The medicine storage bar 200 can slide on the drawer bottom plate 102 of the drawer frame 100. A horizontal post 280 is fixed on the innermost (closest to the deepest part of the drawer) medicine storage bar 200. The horizontal post 280 passes through the through hole of the inner end plate 101 of the drawer frame 100. A compression spring (not shown in the figure) is sleeved on the horizontal post 280 between the innermost medicine storage bar 200 and the inner end plate 101 of the drawer (see the position marked 281 in the attached figure). The two ends of the compression spring contact the innermost medicine storage bar 200 and the inner end plate 101 of the drawer, respectively. By the compression of the compression spring, all the medicine storage bars 200 are connected and fixed as one unit. In this way, the medicine storage bar 120 is in the correct position, which can bring convenience to the subsequent automatic medicine detection operation.

[0031] like Figure 1-5 To prevent misalignment, the medicine storage horizontal plate 200 is U-shaped, and its vertical plate 226 is provided with mounting holes 225 or alignment holes 224. The mounting hole 225 is connected to the positioning post 223. At two adjacent medicine storage horizontal plates 200, one vertical plate 226 is provided with alignment holes 224, and the other vertical plate 226 is provided with positioning posts 223. The positioning posts 223 extend into the alignment holes 224 to achieve axial (axial direction of the horizontal column 280) positioning.

[0032] When storing medicines, the smaller medicine 902 is thinner, while the larger medicine 901 is thicker. The larger medicine 901 occupies more space than the smaller medicine 902. To achieve standardization in processing, or to facilitate interchangeability between the larger medicine 901 and the smaller medicine 902 during use, the following improvements are made: like Figure 1-5 The storage plate 200 corresponding to small medicine 902 is a standard plate 221, and the storage plate 200 corresponding to large medicine 901 is a combination of standard plate 221 and adjustment plate 222.

[0033] When storing medicines, the smaller medicine 902 is shorter, and the larger medicine 901 is longer. The medicine unit 300 corresponding to the smaller medicine 902 is further out. To facilitate assembly, the following improvements are made: like Figure 5 , Figure 7 The medicine unit 300 includes a medicine unit inclined plate 310, which has multiple rows of first screw holes 311 and a medicine storage horizontal bar inclined plate 210, which has multiple rows of second screw holes 211. The first screw holes 311 and the second screw holes 211 are threadedly connected to fastening bolts 212. By tightening the fastening bolts 212, the medicine unit inclined plate 310 and the medicine storage horizontal bar inclined plate 210 are fixed together.

[0034] In this way, if it is assembling the drug unit 300 corresponding to the small drug 902, the upper second screw hole 211 is used; if it is assembling the drug unit 300 corresponding to the large drug 901, the lower second screw hole 211 is used, which brings convenience to the assembly.

[0035] like Figure 2 To facilitate the dispensing and replenishment of medicine, the medicine unit 300 is set at an angle, with an acute angle between it and the horizontal column 280.

[0036] Its working principle is as follows: like Figure 1-9 The method for retrieving and replenishing medicines, using the aforementioned first-in-first-out medicine drawer, includes the following steps: Removing the medicine includes steps S10-S12, as follows: S10. Open the drawer; S11, the rightmost position of the storage bar 120 (that is...) Figure 2 Take out the medicine 900 (from the left side); S12. Close the drawer.

[0037] The supplementary medication includes steps S20-S23, as follows: S20. Open the drawer; S21. Use one hand to move the leftmost (i.e., the medicine storage bar 120) to the leftmost position. Figure 2 The drug 900 (to the right) moves to the right until the originally empty drug unit 300 is "occupied" by the moved drug 900. During the movement of the drug unit 300, the drug unit 300 presses against the partition 400, causing the partition 400 to rotate along the axis of the rotating shaft 410—the partition 400 cannot stop the movement of the drug unit 300. After the medicine unit 300 passes the partition 400, the partition 400 returns to a vertical state under the action of the return spring. To add some explanation, the purpose of setting up the partition 400 is to prevent the two medicine units 300 from colliding with each other.

[0038] To add some explanation, because the blocking block 340 is set up, the partition 400 can only rotate in one direction when it is in a vertical state, which eliminates the reverse operation when replenishing medicine and implements the "first-in, first-out" principle.

[0039] S22. At this time, the leftmost (that is...) Figure 2 (To the right) Medicine unit 300 becomes empty, and new medicines can be manually added to this empty space; S23. Close the drawer.

[0040] It should be noted that: In step S11 above, the rightmost medicine 900 is used because it is the first medicine added, ensuring the "first-in, first-out" principle. In step S21 above, the earliest added medicine is moved to the first-used position; in step S22 above, the last added medicine is placed in the last-used position, ensuring the "first-in, first-out" principle.

[0041] In this way, the "first-in, first-out" principle is followed in both the removal (use) and replenishment of medication.

[0042] The technical contribution of this application is as follows: This application designs the partition 400 between the two drug units 300 as a rotating type, and with the help of a return spring, it facilitates the translation of the drug in the above step S22, so that the "first-in, first-out" principle can be successfully implemented.

[0043] When changing the positions of large medicine 901 and small medicine 902, the following steps are included: S30. First, identify the medicine storage bar 120 on the inside of the medicine to be replaced. See Figure 2 For example, if the positions of medicine A905 and medicine B906 need to be changed, the storage bar 120 where medicine B906 is located is the storage bar 120 closer to the inside.

[0044] S31. Determine that the medicine storage bar 120 adjacent to the inside of the medicine storage bar 120 is the "movable medicine storage bar"; In the example above, the storage bar 120 where drug C907 is located is the "movable storage bar".

[0045] S32. Manually push the "movable medicine storage bar" towards the inside of the drawer (that is...) Figure 2 Move the left side of the device by a displacement to disengage the "movable medicine storage bar" (that is, the positioning pin 223 disengages from the alignment hole 224) and provide a larger space for replacement; then, keep the hand pressing on the "movable medicine storage bar" to prevent it from resetting.

[0046] During this process, the "compression spring" is further compressed.

[0047] S33. Easily pull out the medicine storage strip 120 (the medicine storage strip 120 where medicine A905 and medicine B906 are located) of the medicine to be replaced.

[0048] This step is relatively easy because both are unidirectional constraints.

[0049] S34. Following the new order, reassemble the two medicine storage strips 120 (the medicine storage strips 120 where medicine A905 and medicine B906 are located).

[0050] This step is relatively easy because there is a large installation space due to the pressure applied by hand to the "movable medicine storage bar".

[0051] S35. Release the hand pressing the "moving medicine storage bar", and rely on the elastic force of the "compression spring" to reconnect the "positioning post 223 and alignment hole 224" that were just disconnected, and the process ends.

[0052] Finally, let's explain the First-In-First-Out (FIFO) principle: First-In, First-Out (FIFO) is an inventory management principle that states that medicines purchased or produced earlier should be used first, and those purchased later should be used later. Its core purpose is to ensure that stored medicines do not exceed their expiration date due to prolonged storage, thereby guaranteeing medication safety.

[0053] This is crucial for emergency medications, because medications used in emergency situations must be 100% effective. Any ineffective medication could lead to a failed rescue and irreversible consequences.

[0054] The "first-in, first-out" principle for emergency medications is not just a slogan, but a meticulously implemented management system. Through standardized storage, clear labeling, standardized procedures, and a strong sense of responsibility among all staff, it collectively builds a solid defense for patient safety.

[0056] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be considered within the scope of protection of the present invention.
