Description

Technical Field

[0001] This invention relates to the field of medical kit technology, specifically to a nursing medical kit with a foldable support frame. Background Technology

[0002] As the name suggests, a medical kit is a container for storing medicines and medical equipment, which can be taken out and used in case of emergency. When using a medical kit, a set of medicines or medical equipment for a certain department or use is usually packed together in one or more specially made packages. This kind of package is fixed, classified and numbered, and is called a medical kit. Medical kits are widely used because of their portability. Therefore, we have launched a nursing medical kit with a foldable support frame.

[0003] An existing patent (publication number: CN117257480A) discloses a nursing medical case with a foldable support frame, relating to the field of medical cases. It includes a mounting box, a lid, and a second partition layer. The lid is hinged to the top of the mounting box. A second and third partition layer are inserted inside the mounting box. Shoulder straps are installed on both sides of the mounting box. A buckle is installed on the top of the lid. A first partition layer is located on the upper side of the mounting box. A partition plate is provided between the second and third partition layers. This nursing medical case with a foldable support frame, when activated, uses a rotating shaft to drive a winding roller to wind up an adjusting rope connected to an adjusting rod until the adjusting rod is adjusted to a suitable position. The downward movement of the adjusting rod causes the folding rod inside the folding support mechanism to press downwards. This solves the problem that the internal partition layer of a nursing case has a fixed height, resulting in limited support for internal equipment. The existing technology has the following problems: the existing nursing medical kits rely on a drive mechanism to unfold the layers of the medical kit to facilitate the retrieval of medicines. The whole process requires opening the medical kit first, and then activating the drive mechanism to unfold the layers. Moreover, the drive mechanism is driven by a threaded rod, which has slow transmission efficiency and takes a long time to unfold. In case of emergency, it will delay the best treatment time. Furthermore, if used at night or in poor lighting conditions, an external light source is required for illumination and to retrieve medicines, which is not convenient to use. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In this invention, opening the lid unfolds both the upper and lower shelves. Simultaneously, the opening of the lid triggers a locking mechanism via a drive linkage, releasing the drawer from its lock. The opening also causes a curved arm to move a connecting rope, which pulls the drawer outwards, facilitating easy access to medications. As the medical case opens, internal LED strips automatically connect to their corresponding power sources and illuminate; conversely, closing the lid extinguishes the LED strips. After closing, a disinfection component sprays disinfectant into the case, automatically disinfecting the interior and preventing external bacteria from entering. The lifting rod, when closed, can be positioned at the top for easy carrying. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 10 The present invention provides a technical solution: a foldable and storable nursing medical box with a support frame, including a box body 1 and a box cover 2. The box body 1 and the box cover 2 are hinged together by a hinge. A storage shelf assembly 3 is provided between the two walls of the box body 1. Locking components 4 are provided on both sides of the storage shelf assembly 3. A disinfection component 5 is fixedly connected to the inner top surface of the box cover 2. Two T-shaped sliding grooves 6 are opened on the inner bottom surface of the box body 1.

[0031] In this embodiment, as Figure 1As shown, the retractable shelf assembly 3 includes a T-shaped slide bar 301 slidably connected inside the T-shaped slide groove 6 and a folding connecting rod 302 rotatably connected to both sides of the cabinet 1. The T-shaped slide bar 301 is integrally formed on the bottom surface of the drawer 303. A fixing plate 304 is fixedly connected to the inner corner of the drawer 303. A spring 305 is fixedly connected to the side of the fixing plate 304 near the outside of the drawer 303. A moving block 306 is fixedly connected to the end of the spring 305 away from the fixing plate 304. The top of the moving block 306 is connected to a power supply 307. The power supply 307 is connected to the end of the light strip 308. Holes are opened on the side wall of the drawer 303. The top of the folding connecting rod 302 is rotatably connected to a lower shelf 309 and an upper shelf 3010 respectively. A pressing block 301 passes through one edge of the upper shelf 3010. 1. The top of the extrusion block 3011 is connected to the power supply 3012. The two sides of the extrusion block 3011 are fixedly connected to the spring 3013 through the extension plate. The top of the spring 3013 is fixedly connected to the bottom surface of the upper plate 3010. The bottom surface of the inner side of the lower plate 309 is fixedly connected to the spring 3014. The power supply 3015 is provided between the tops of the spring 3014. The folding linkage 302 is divided into a single linkage 302a, a drive linkage 302b and a pull linkage 302c. The end of the pull linkage 302c away from the upper plate 3010 is rotatably connected to the side wall of the box cover 2. The single linkage 302a is used to connect the upper plate 3010 and the lower plate 309, and the lower plate 309 and the box body 1. The drawer 303, the top of the inner wall of the upper plate 3010 and the lower plate 309 are all provided with light strips 308.When the nursing medical kit needs to be opened, the unlocked lid 2 is opened. During the opening process, the lid 2 pulls the upper shelf 3010 upward via the connecting rod 302c. The upper shelf 3010, in turn, pulls the lower shelf 309 upward and unfolds via the connecting rod 302a. When the angle between the lid 2 and the kit body 1 is obtuse, the lid 2 can prevent the shelves from resetting under the action of gravity. This structure unfolds the upper shelf 3010 and the lower shelf 309 simultaneously with opening the lid 2, achieving... To achieve an open-and-unfold effect, compared to traditional nursing medical boxes, the time required for the shelves to unfold is greatly shortened. Furthermore, when the nursing box is closed, the bottom surface of the compression block 3011 contacts the top surface of the power supply 3014. At this time, the compression block 3011 and the power supply 3014 compress the springs 3013 and 3014 respectively, causing the power supplies 3015 and 3012 to be disconnected from their corresponding LED strips 308. When the lid 2 is opened, the compression block 3011... Disconnected from power supply 3015, under the restoring force of springs 3013 and 3014, the pressing block 3011 and power supply 3015 reset. Power supply 3015 and power supply 3012 driven by the pressing block 3011 then connect to their respective LED strips 308, illuminating the LED strips 308. This facilitates the use of the nursing medical kit in low-light conditions. The LED strips 308 inside drawer 303 are controlled to light up and turn off by the displacement of the locking lever 407. When locked... When the locking lever 407 is inserted into the opening in the side wall of drawer 303, the locking lever 407 pushes the moving block 306 inward toward the fixed plate 304, compressing the spring 305. Simultaneously, the moving block 306 disengages the power supply 307 from the LED strip 308 inside drawer 303, turning off the LED strip 308. Conversely, when the locking lever 407 disengages from the opening and releases the lock on drawer 303, the spring 305 returns to its original position, causing the power supply 307 to reconnect with the LED strip 308 and illuminate.

[0032] In this embodiment, as Figure 1 As shown, the bottom surfaces of both the upper shelf 3010 and the lower shelf 309 are covered with sponge pads 3016; when the medical box is closed, the sponge pads 3016 can compress the medicines below, preventing the medicines inside from shaking violently and hitting the inner walls of the shelf or drawer 303 and breaking during the movement of the medical box.

[0033] In this embodiment, as Figure 1As shown, the rear ends of drawer 303 are fixedly connected to one end of connecting rope 3017, and the other end of connecting rope 3017 is fixedly connected to an arc-shaped arm 3018. Connecting rope 3017 passes through the front of box 1 in a "U" shape. Arc-shaped groove 3019 is provided in the middle of arc-shaped arm 3018. Arc-shaped arm 3018 is slidably connected to arc-shaped block 3020 through arc-shaped groove 3019. Arc-shaped retractable rod 3026 and arc-shaped spring 3021 are fixedly connected to the end of arc-shaped arm 3018 away from connecting rope 3017, respectively. Arc-shaped storage arm 3026 is fixedly connected to the end of arc-shaped spring 3021 away from arc-shaped arm 3018. 22. A storage groove 3023 is provided in the middle of the inner side of the arc-shaped storage arm 3022. The arc-shaped retractable rod 3026 extends into the storage groove 3023. The end of the arc-shaped storage arm 3022 away from the arc-shaped spring 3021 is connected to the outer top surface of the lid 2 through a hinge seat. A slider 3024 is slidably connected to the outer surface of the arc-shaped arm 3018. A lifting rod 3025 is integrally formed on one side of the slider 3024. A limit block is integrally formed at the end of the arc-shaped arm 3019 near the arc-shaped spring 3021. A limit block is also provided at the end of the arc-shaped retractable rod 3026 that is inserted into the storage groove 3023. The lid 2 is opened... During the process, the lid 2 will drive the arc-shaped storage arm 3022 to move. Since the end of the arc-shaped arm 3018 inside the box 1 is blocked by the drawer 303, the lid 2 will drive the subsequent arm 3018 to compress the arc-shaped spring 3021. At this time, the arc-shaped retraction rod 3026 will be inserted into the arc-shaped groove 3019. After the locking component 4 releases the lock on the drawer 303, the arc-shaped spring 3021 will rebound, and the end of the arc-shaped arm 3018 inside the box 1 will drive the connecting rope 3017 to pull the drawer 303 outward along the T-shaped slide 6, realizing the automatic opening of the drawer 303, so as to facilitate medical staff. When searching for medicines in drawer 1, it's important to note that the curved retractable lever 3026 is designed to prevent jamming when opening the medical kit. Unlocking drawer 303 takes time; more specifically, it takes time to pull the locking lever 407 out of the hole in the side wall of drawer 303. During this time, the curved arm 3018 is blocked by drawer 303 and cannot move. Without the curved retractable lever 3026, the lid 2 cannot be opened, and without opening the lid 2, the locking assembly 4 cannot unlock drawer 303, creating a vicious cycle. Therefore, the curved retractable lever 3026 is essential.

[0034] In this embodiment, as Figure 1As shown, the locking assembly 4 includes a main pulley 401 fixedly connected to the bottom end of the drive linkage 302b via a connecting shaft. A synchronous belt 402 is movably connected to the outer side of the main pulley 401. One side of the synchronous belt 402 is movably connected to a secondary pulley 403. The secondary pulley 403 is rotatably connected to the outer wall of the housing 1 via a connecting shaft. A cylindrical tube 404 is integrally formed on the side of the secondary pulley 403 away from the housing 1. A spiral groove 405 is formed in the middle of the cylindrical tube 404. A guide rod 406 is movably inserted into the middle of the spiral groove 405. One end of the guide rod 406 extending to the outside of the cylindrical tube 404 is connected to a locking rod 407. The stop rod 407 is slidably inserted into the middle of the side wall of the box 1. During the opening of the box lid 2, the drive linkage 302b will drive the main pulley 401 to rotate. The main pulley 401 drives the auxiliary pulley 403 to rotate through the synchronous belt 402. The auxiliary pulley 403 drives the cylindrical cylinder 404 to rotate. When the cylindrical cylinder 404 rotates, it will drive the guide rod 406 to move along the axis of the cylindrical cylinder 404 through the spiral groove 405. The movement of the guide rod 406 will drive the locking rod 407 to move away from the drawer 303, thereby pulling the locking rod 407 out of the hole in the side wall of the drawer 303 and releasing the lock on the drawer 303.

[0035] In this embodiment, as Figure 1As shown, the disinfection assembly 5 includes a water bag 501 fixedly connected to the top inner surface of the lid 2. Four connecting pipes 502 are connected to both sides of the water bag 501. The end of each connecting pipe 502 away from the water bag 501 is connected to the end of the disinfection chamber 503. The interior of the disinfection chamber 503 is divided into a hydraulic chamber 503a, a squeezing chamber 503b, and a replenishment chamber 503c. The hydraulic chamber 503a and the squeezing chamber 503b are separated by a piston 504. A return spring 505 is provided on the side of the piston 504 closest to the hydraulic chamber 503a. The squeezing chamber 503b is located away from the top of the lid 2. A squeezing nozzle 506 is provided on one side of the surface. A first partition 507 and a second partition 508 are fixedly connected between the squeezing chamber 503b and the replenishment chamber 503c. A flow hole 509 is provided at the corner of the first partition 507, and a flow hole 509 is provided in the middle of the second partition 508. A blocking ball 5010 is provided between the first partition 507 and the second partition 508. After the medical kit is used, the lid 2 is closed. The water bag 501 on the top surface of the lid 2 will come into contact with the medicine in the upper plate 3010 and be squeezed by the medicine. The liquid in the water bag 501 flows through the connecting pipe 50... 2. The fluid is squeezed into the hydraulic chamber 503a. At this time, the piston 504 moves towards the side where the squeezing chamber 503b is located, and the piston 504 stretches the return spring 505. During the initial stage of the piston 504's movement, the disinfectant in the squeezing chamber 503b flows simultaneously into the replenishment chamber 503c and the squeezing nozzle 506. During the flow, the disinfectant flowing out of the squeezing nozzle 506 is sprayed into the housing 1 for disinfection, while the disinfectant flowing into the replenishment chamber 503c will drive the blocking ball 5010 to approach the second partition 508, and finally block the middle part of the second partition 508. When the flow hole 509 is blocked, the disinfectant can only be sprayed from the squeeze nozzle 506. Conversely, when the lid 2 is opened, the water bag 501 loses its pressure, and the return spring 505 rebounds, causing the piston 504 to return to its original position. At this time, under the action of negative pressure, the disinfectant inside the replenishment chamber 503c causes the blocking ball 5010 to move closer to the partition 507. Since the flow hole 509 at the corner of the partition 507 is not blocked by the blocking ball 5010, the blocking ball 5010 will not affect the flow of disinfectant from the replenishment chamber 503c to the squeeze chamber 503b.

[0036] The method of use and advantages of this invention: When using this foldable and storable nursing medical box with a support frame, the working process is as follows:

[0037] When the medical case needs to be used, the lid 2 is opened. Simultaneously, the upper shelf 3010 and lower shelf 309 unfold. During the opening process, the driving linkage 302b releases the locking component 4 from the drawer 303. At the same time, the opening of the lid causes the arc arm 3018 to move the connecting rope 3017, which pulls the drawer 303 outwards from the case body 1, automatically unfolding the drawer for easy access to medications. Simultaneously, the internal light strip 308 automatically connects to its corresponding power source and illuminates when the medical case is opened. Conversely, the light strip 308 turns off when the lid 2 is closed. After closing the lid 2, the disinfection component 5 sprays disinfectant into the case body 1, automatically disinfecting it and preventing external bacteria from entering during opening. After the medical case is closed, the lifting rod 3025 can be placed at the top for easy lifting and carrying.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
