The tray has a protrusion that can pass through the first through hole. The protrusion has a second through hole that runs vertically through the box. Inside the second through hole is a second partition corresponding to the first partition. The second partition divides the inside of the second through hole into multiple vertically through channels. The multiple channels correspond one-to-one with multiple first chambers, so that medical waste can enter the corresponding first chamber through the channels.

[0012] Preferably, the side of the enclosure is provided with a viewing window made of transparent material.

[0013] Preferably, the bottom of the outer side of the box is provided with multiple pulleys at one end and multiple support feet at the opposite end, so as to facilitate dragging and moving the box and prevent the box from moving on its own.

[0014] Preferably, the side of the box is provided with a drain outlet, and a first plug for sealing is detachably connected to the drain outlet. The bottom of the inner side of the box is inclined, and the end of the bottom of the inner side of the box away from the drain outlet is higher than the end near the drain outlet, so as to facilitate the discharge of liquid.

[0015] Preferably, the interior of the housing is provided with a water filter located above the drain outlet. The top of the water filter is connected to the first partition. There is a gap between the bottom of the water filter and the bottom of the inner side of the housing. The lower part of the water filter and the housing can form a second chamber, so that the medical waste in the first chamber can be separated into solid and liquid components.

[0016] Preferably, the side of the box body is provided with multiple limiting protrusions, and the side of the cover body is rotatably connected with multiple limiting members. The multiple limiting members and the multiple limiting protrusions correspond one-to-one, and the limiting members are provided with limiting grooves corresponding to the limiting protrusions. The limiting members can be fastened to the limiting protrusions through the limiting grooves to connect and fix the cover body and the box body.

[0017] Preferably, the tray has a horizontal first edge on its side, a vertical second edge on its top, and a vertical positioning protrusion on its bottom. The top of the box has a positioning hole corresponding to the positioning protrusion. The bottom of the first edge abuts against the top of the box, and the top of the first edge abuts against the bottom of the cover, so that the gap between the tray and the box directly connects to the outside, thereby preventing the volatilization of medical waste in the first chamber from contaminating the items on the tray. The side of the second edge is slidably connected to the side of the cover to position the cover. The positioning protrusion can be inserted into the positioning hole to position the tray.

[0018] Preferably, the tray also includes multiple third partitions. The interior of the tray is provided with multiple sets of linearly arranged first slots. Each set of first slots consists of two opposing first slots. Each set of first slots can be plugged into and detachably connected to one of the third partitions.

[0019] Preferably, the system further includes multiple fourth partitions. The upper part of the third partition is provided with multiple linearly arranged second slots, and the lower part of the fourth partition is provided with multiple third slots corresponding to the third partition and the second slots. The fourth partition and the third partition can be plugged and unplugged through the cooperation of the third slots and the second slots, and the third chamber is divided into multiple fourth chambers to further increase the space utilization of the tray.

[0020] Preferably, the case is provided with a shoulder strap for carrying on the back; the top of the case is provided with an outwardly folded third edge for gripping and carrying; the cover is provided with a handle for lifting; and the top of the protrusion is detachably connected to a second plug for sealing the second through hole.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] Since the tray connects to the lower part of the box through the second through hole, medical supplies and medical waste can be stored simultaneously without removing the tray after the lid is opened, making storage convenient. Furthermore, since the protrusion can pass through the first through hole on the lid, medical waste can be placed into the lower part of the box without opening the lid, making medical waste storage even easier.

[0024] Because the lower part of the box is divided into multiple first chambers by the first partition, and the second through hole is divided into multiple channels corresponding to the first chambers by the second partition, different types of medical waste can be disposed of into different first chambers through different channels to achieve the purpose of classified storage, such as sharps, non-sharps, liquids, and non-solids.

[0025] Because the gap between the tray and the container is located outside the lid, and the top of the second through hole is also located outside the lid, even if there are volatile substances in the medical waste, these substances cannot enter the space above the tray and below the lid after evaporation. Therefore, it can effectively prevent the medical supplies placed on the tray from being contaminated by the medical waste. In addition, since there is no need to pick up and put down the tray when disposing of medical waste, it can also effectively prevent the medical supplies placed on the tray from being contaminated.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] See appendix Figure 1 Appendix Figure 5 Appendix Figure 7 and attached Figure 8This utility model discloses a medical storage device, including a box 1, a cover 2, and a tray 3. The box 1 has an opening at the top and at least one first partition 4 inside, which divides the interior of the box 1 into multiple first chambers 101 with openings at the top for storing different medical wastes. The cover 2 is detachably connected to the top of the box 1 for covering the box 1, and has a through hole 21 extending vertically. The tray 3 is detachably connected to the top of the box 1 and can be covered by the cover 2 for... The tray 3 and the box 1 are used to store medical supplies. The gap between them is located outside the cover 2. The tray 3 is provided with a protrusion 31 that can pass through the first through hole 21. The protrusion 31 is provided with a second through hole 32 that runs vertically through the box. The inside of the second through hole 32 is provided with a second partition 5 that corresponds to the first partition 4. The second partition 5 can divide the inside of the second through hole 32 into multiple vertically running channels 321. The multiple channels 321 correspond one-to-one with multiple first chambers 101, so that medical waste can enter the corresponding first chamber 101 through the channels 321.

[0043] In actual use, opening the cover 2 on the box 1 allows medical supplies to be placed on the tray 3, while medical waste generated during patient treatment can be disposed of through the second through hole 32 on the protrusion 31 into the lower part of the box 1. Since the tray 3 connects to the lower part of the box 1 through the second through hole 32, medical supplies and medical waste can be stored simultaneously without removing the tray 3 after the cover 2 is opened, facilitating storage. Since the protrusion 31 can pass through the first through hole 21 on the cover 2, medical waste can be disposed of into the lower part of the box 1 without opening the cover 2, making medical waste easier to store. Because the lower part of the box 1 is divided into multiple first chambers 101 by the first partition 4, and the second through hole 32 is divided into multiple channels 321 corresponding to the first chambers 101 by the second partition 5, different types of medical waste can be disposed of through the first partition 4. Medical waste is disposed of through different channels 321 into different first chambers 101 for classified storage, such as sharps, non-sharp objects, liquids, and non-solids. Since the gap between the tray 3 and the box 1 is located outside the cover 2, and the top of the second through hole 32 is also located outside the cover 2, even if there are volatile substances in the medical waste, these substances cannot enter the space above the tray 3 and below the cover 2 after evaporation. Therefore, it can effectively prevent the medical supplies placed on the tray 3 from being contaminated by the medical waste. In addition, since there is no need to pick up and put down the tray 3 when disposing of medical waste, it can also effectively prevent the medical supplies placed on the tray 3 from being contaminated. In summary, by using this medical storage device, it is convenient to store medical supplies and medical waste, medical waste can be classified and stored, and medical waste can be prevented from contaminating medical supplies.

[0044] See appendix Figure 1In order to facilitate observation of the storage situation at the bottom of the box 1, the following design was made in this embodiment: Specifically, the side of the box 1 is provided with a viewing window 6 made of transparent material.

[0045] The above-described structure allows for real-time monitoring of the amount of medical waste within the first chamber 101, enabling timely cleaning.

[0046] See appendix Figure 1 and attached Figure 2 In order to facilitate the movement and fixation of the box 1 after placement, the following design is made in this embodiment: Specifically, one end of the bottom of the outer side of the box 1 is provided with multiple pulleys 7, and the other end is provided with multiple support feet 8.

[0047] With the above structural design, the side of the box 1 with the support foot 8 is lifted. Since it is not necessary to lift the entire box 1 completely, and the pulley 7 can roll, the box 1 can be easily dragged and moved. After the box 1 is moved to the designated position, the side of the box 1 with the support foot 8 is lowered. Since the damping between the support foot 8 and the ground is obviously large, the box 1 can also be prevented from moving on its own.

[0048] See appendix Figure 2 Appendix Figure 6 and attached Figure 12 Medical waste often contains waste liquid. In order to facilitate the discharge of the above-mentioned waste liquid, the following design is made in this embodiment. Specifically, the side of the box 1 is provided with a drain outlet 102, and a first plug 103 for sealing is detachably connected to the drain outlet 102. The bottom of the inner side of the box 1 is inclined, and the end of the bottom of the inner side of the box 1 away from the drain outlet 102 is higher than the end near the drain outlet 102.

[0049] With the design of the above structure, the liquid at the bottom of the tank 1 can be discharged by opening the first plug 103. Since the bottom of the inner side of the tank 1 is inclined and the end of the bottom of the inner side of the tank 1 that is away from the drain outlet 102 is higher than the end that is close to the drain outlet 102, the liquid can be discharged more quickly and thoroughly.

[0050] See appendix Figure 5 and attached Figure 6 Based on the above solution, in order to avoid solid medical waste being discharged during the liquid discharge process, the following design is made in this embodiment. Specifically, the interior of the box 1 is provided with a water filter 9 located above the drain outlet 102. The top of the water filter 9 is connected to the first partition 4. There is a gap between the bottom of the water filter 9 and the bottom of the inner side of the box 1. The bottom of the water filter 9 and the box 1 can form a second chamber 104 so that the medical waste in the first chamber 101 can be separated into solid and liquid.

[0051] With the above structural design, medical waste falls into the first chamber 101 and then falls above the filter element 9. Therefore, under the action of gravity, the medical waste will undergo solid-liquid separation at the filter element 9. That is, solid medical waste remains in the first chamber 101 above the filter element 9, while liquid medical waste passes through the filter element 9 and enters the second chamber 104 below it. In addition, since the filter element 9 is located above the drain outlet 102, the solid waste in the first chamber 101 will not be carried to the outside of the box 1 with the outflow of liquid.

[0052] See appendix Figure 2 and attached Figure 3 There are various ways and structures for detachable connection. For the connection between the box body 1 and the cover 2, this embodiment introduces one design structure. Specifically, the side of the box body 1 is provided with multiple limiting protrusions 105, and the side of the cover 2 is rotatably connected with multiple limiting members 14. The multiple limiting members 14 correspond one-to-one with the multiple limiting protrusions 105, and the limiting members 14 are provided with limiting grooves 141 corresponding to the limiting protrusions 105. The limiting members 14 can be snapped to the limiting protrusions 105 through the limiting grooves 141 to connect and fix the cover 2 and the box body 1.

[0053] With the above structural design, the cover 2 is placed on the box 1, and the limiting member 14 is rotated so that the limiting protrusion 105 enters the limiting groove 141, thus completing the connection and fixation of the cover 2 and the box 1.

[0054] It should be noted that at least one of the limiting member 14 and the limiting protrusion 105 should be made of an elastic material so that the connection between the two can deform and be snapped together.

[0055] See appendix Figure 2 -Appendix Figure 4 In order to make the gap between the tray 3 and the box 1 located outside the cover 2, the following design is made in this embodiment. Specifically, the side of the tray 3 is provided with a horizontal first edge 33, the bottom of the first edge 33 abuts against the top of the box 1, and the top of the first edge 33 abuts against the bottom of the cover 2, so that the gap between the tray 3 and the box 1 can directly communicate with the outside, thereby preventing the volatilization of medical waste in the first chamber 101 from contaminating the items on the tray 3.

[0056] See appendix Figure 4 Appendix Figure 5 and attached Figure 9Furthermore, the following design is also made in this embodiment: Specifically, the top of the tray 3 is provided with a vertical second edge 34, the bottom of the tray 3 is provided with a vertical positioning protrusion 35, and the top of the box body 1 is provided with a positioning hole 106 corresponding to the positioning protrusion 35; the side of the second edge 34 is slidably connected to the side of the cover 2 to position the cover 2; the positioning protrusion 35 can be inserted into the positioning hole 106 to position the tray 3.

[0057] See appendix Figure 4 and attached Figure 10 In order to increase the space utilization of the tray 3, the following design is made in this embodiment. Specifically, it also includes multiple third partitions 10. The interior of the tray 3 is provided with multiple sets of linearly arranged first slots 36. Each set of first slots 36 consists of two opposing first slots 36. A set of first slots 36 can be plugged into and detached to a third partition 10. The third partition 10 can divide the interior of the tray 3 into multiple third chambers 37, thereby storing medical supplies and classifying different medical supplies.

[0058] With the above structural design, the third partition 10 can be connected by inserting it into the two opposite first slots 36 in the same group. When removing it, it can be pulled upward along the extension direction of the first slot 36. The disassembly and assembly are convenient and quick. In addition, by adjusting the number and position of the third partition 10, the size of different third chambers 37 can also be adjusted.

[0059] See appendix Figure 4 and attached Figure 11 Based on the above scheme, the following design is also made in this embodiment. Specifically, it also includes a plurality of fourth partition members 11. The upper part of the third partition member 10 is provided with a plurality of linearly arranged second slots 1001. The lower part of the fourth partition member 11 is provided with a plurality of third slots 111 corresponding to the third partition member 10 and the second slots 1001. The fourth partition member 11 and the third partition member 10 can be plugged and unplugged through the cooperation of the third slots 111 and the second slots 1001, and the third chamber 37 is divided into a plurality of fourth chambers 371.

[0060] With the above-described structure, after the fourth partition 11 is plugged into and connected to the third partition 10 through the cooperation of the third slot 111 and the second slot 1001, the space utilization of the tray 3 can be further increased. In addition, by adjusting the number and position of the fourth partition 11, the size of different fourth chambers 371 can also be adjusted.

[0061] See appendix Figure 1 Appendix Figure 3 and attached Figure 13In order to facilitate the use of the medical storage device, the following design is also made in this embodiment. Specifically, the box body 1 is provided with a shoulder strap 12 for carrying on the back; the top of the box body 1 is provided with an outwardly folded third edge 107 for gripping and carrying; the cover body 2 is provided with a handle 13 for lifting; the top of the protrusion 31 is detachably connected with a second plug 38 for sealing the second through hole 32.

[0062] Through the design of the above structure, the shoulder strap 12, the third edge 107 and the handle 13 make the medical storage device easier to carry and move; while the second plug 38 can seal the top of the second through hole 32 to a certain extent seal the medical waste in the first chamber 101 and prevent the volatile substances in the medical waste from evaporating to the outside.
