[0002] A first aid kit is a key piece of equipment for providing preliminary medical intervention in emergencies.

[0003] There are significant differences in the first aid needs of different patient groups. For example, during the rescue of medical emergencies, it is usually necessary to carry cardiac stimulants, oximeters, and auxiliary drugs. When performing first aid for surgical traumas, hemostatic instruments, debridement tools, and anti-infection drugs, etc., need to be equipped; for another example, when performing first aid for children, pediatric masks and accurately dosed drugs usually need to be prepared, while when performing first aid for the elderly, first aid drugs for chronic diseases need to be equipped.

[0004] Existing first aid kits are usually of an integral design, with the problem of mixed storage of various instruments and drugs. It is easy to mis-take non-matching items during rescue. Although existing first aid kits have a layered design, due to the inability to perform modular quick disassembly and replacement, they cannot fully meet the above different types of rescue needs. In addition, during on-site rescue, there are defects such as cumbersome operations when opening the first aid kit and taking out instruments or drugs, which affect the rescue efficiency.

Detailed implementation manners

[0037] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0038] The quick-detachable layered modular first-aid kit according to the embodiments of the present application will be described below with reference to the accompanying drawings.

[0039] As Figure 1 and Figure 2 shown, the quick-detachable layered modular first-aid kit according to the embodiments of the present application may include a box body 100, a box cover 200, a handle switch 300, an outward pushing and unfolding device 400, a first-aid module bin 500, and a covering and blocking device 600.

[0040] Among them, the box cover 200 is openably and closably arranged at the front end of the box body 100 through the handle switch 300, and an abutting block 201 is arranged on the top of the box cover 200.

[0041] It should be noted that a latch is provided on the lid 200. By pressing the handle switch 300, the latch is disengaged from the handle switch 300 to realize the opening and closing of the lid 200. To reduce the accidental touch of the handle switch 300 by medical staff, a notch is provided on the outer side of the box body 100, and the handle switch 300 is rotatably arranged at the notch of the groove body. The handle switch 300 is embedded to reduce the risk of accidental touch.

[0042] The outward pushing and unfolding device 400 includes an unfoldable rack 410 and an elastic outward pushing structure 420. Among them, the outward pushing structure 420 and the rack 410 are sequentially arranged in the box body 100, and the front and rear ends of the rack 410 are respectively abutted against the lid 200 and the pushing end of the outward pushing structure 420.

[0043] The first aid module bin 500 is detachably arranged on the top of the box body 100. The first aid module bin 500 includes a flat carrying rack 510 that can be unfolded from the top center to the left and right sides and an elastic rod 520 arranged in the flat carrying rack 510 to drive the flat carrying rack 510 to unfold.

[0044] The lid closing and blocking device 600 is arranged on the first aid module bin 500, and the two lid closing ends of the lid closing and blocking device 600 are respectively symmetrically rotatably closed at the front and rear ends of the top center of the flat carrying rack 510 to limit the elastic release of the elastic rod 520. Among them, the abutting block 201 abuts against the lid closing end at the front end of the lid closing and blocking device 600 to limit the rotation of the lid closing end of the lid closing and blocking device 600 through the abutting block 201.

[0045] Among them, fixing members 700 for fixing first aid drugs and instruments are arranged in both the rack 410 and the flat carrying rack 510.

[0046] It should be noted that conventional drugs and instruments can be arranged on the rack 410 through the fixing member 700, while targeted drugs and instruments can be arranged on the flat carrying rack 510 through the fixing member 700. For example, according to the differences in internal and surgical first aid or different age groups, corresponding drugs and instruments are respectively arranged in the flat carrying rack. Thus, medical staff can select the corresponding first aid module bin 500 according to different first aid populations and first aid situations and quickly install it on the box body 100.

[0047] Specifically, after receiving a first aid instruction, medical staff judge the required first aid drugs and instruments according to the basic conditions of the person to be first aid, select the corresponding first aid module bin 500, install the selected first aid module bin 500 on the box body 100, and rush to the first aid scene.

[0048] After arriving at the scene, the medical staff carried out first aid work. By pressing the handle switch 300, the box cover 200 was triggered to open. Since the display rack 410 lost the abutment of the box cover 200, the outer pushing structure pushed the display rack 410 out of the box body 100 due to elastic reset. After the display rack 410 was pushed out of the box body 100, it unfolded by itself, and the drugs and instruments on the display rack 410 were exposed as the display rack 410 unfolded.

[0049] Due to the opening of the box cover 200, the abutting block 201 on the box cover 200 no longer abutted and blocked the closing end of the closing blocking device 600. Then, the elastic release of the elastic rod 520 drove the flat carrying rack 510 to unfold, and pushed the closing end of the closing blocking device 600 to both the front and back sides. After the flat carrying rack 510 unfolded, the targeted drugs and instruments on it were exposed, facilitating the medical staff to quickly access them.

[0050] As a possible situation, as Figure 13 shown, the fixing member 700 includes a fixing sleeve 710 and a strap 720. Among them, the fixing sleeve 710 is an open sleeve body and is arranged on the display rack 410 or the flat carrying rack 510. The strap 720 is arranged at the opening of the fixing sleeve 710 and is connected to the fixing sleeve 710 through a snap button 730. When the fixing member 700 fixes the instrument, the instrument can be placed in the fixing sleeve 710, and the strap 720 can be buckled on the fixing sleeve 710 to prevent the instrument from falling.

[0051] As another possible situation, as Figure 14 shown, the fixing member 700 includes a fixing frame 740 and a sponge pad 750. The fixing frame 740 is arranged at the central position of the display rack 410 or the flat carrying rack 510, and a through hole is opened on the fixing frame 740. The inner wall of the through hole is embedded with the sponge pad 750. For drugs or columnar instruments, they can be placed in the through hole and squeeze the sponge pad 750 to deform, so as to prevent the drugs or columnar instruments from falling.

[0052] The relevant staff can selectively place them in different fixing members according to the characteristics of the drugs and instruments to ensure their stability during transportation.

[0053] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 3 shown, the display rack 410 includes a central plate 411, a slant plate 412 and an extension plate 413.

[0054] Among them, the central plate 411 is slidably connected to the inner wall of the bottom of the box body 100. Two slant plates 412 are hinged on both sides of the central plate 411. The extension plate 413 is arranged on the side of the central plate 411 away from the box cover 200 and abuts against the pushing end of the outer pushing structure 420.

[0055] In addition, blocking strips 101 are respectively arranged on both sides of the inner wall of the top of the box body 100 to respectively limit the top of the inclined plate 412 between the side wall of the box body 100 and the blocking strip 101, so as to maintain the inclined state of the inclined plate 412.

[0056] It should be noted that when the inclined plate 412 is stored in the box body 100, it maintains an outward inclined state, that is, the included angle between the inclined plate 412 and the central plate 411 is greater than 90 degrees, so that after the display rack 410 is pushed out of the box body 100, the inclined plate 412 can be unfolded to both sides of the central plate 411 under the action of its own gravity.

[0057] It can be understood that in order to avoid the impact caused by the rapid unfolding of the inclined plate 412 after the display rack 410 is pushed out, the hinge between the central plate 411 and the inclined plate 412 is a damping hinge, so as to ensure that after the display rack 410 is pushed out, the inclined plate 412 unfolds smoothly and reduce the damage of drugs and instruments.

[0058] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 5 and Figure 6 shown, the outward pushing structure 420 includes a rotating arm 421, a first torsion spring 422 and a roller 423.

[0059] Among them, the rotating arm 421 is rotatably arranged in the box body 100, the first torsion spring 422 is arranged on the pivot end of the rotating arm 421 to reset the rotating arm 421, and the roller 423 is rotatably arranged on the rotating arm 421 and abuts against the extension plate 413.

[0060] It should be noted that when the display rack 410 is pushed into the box body 100, the extension plate 413 abuts against the roller 423, causing the rotating arm 421 to rotate. At this time, the first torsion spring 422 stores energy. After the box cover 200 is opened, since the display rack 410 lacks a limit, it is reset by the elastic release of the first torsion spring 422, driving the rotating arm 421 to rotate, and pushing the extension plate 413 through the roller 423, so as to push the display rack 410 out of the box body 100.

[0061] In an embodiment of the present application, as Figure 7 and Figure 8 shown, the flat display carrier 510 includes a bottom plate 511, side plates 512 and a top plate 513.

[0062] Among them, the bottom plate 511 is detachably arranged on the top of the box body 100, the two side plates 512 are respectively connected to both sides of the bottom plate 511 through hinge parts, and the two top plates 513 are respectively connected to the two side plates 512 through another two hinge parts;

[0063] It should be noted that the hinge member is a limiting hinge member. When the flat carrying frame 510 is folded, the bending angles between the bottom plate 511 and the side plates 512, and between the side plates 512 and the top plate 513 are limited to 90 degrees. Then, when being stored, the bottom plate 511, the side plates 512, and the top plate 513 jointly enclose a rectangular frame; when the flat carrying frame 510 is unfolded, it is limited that the bottom plate 511, the side plates 512, and the top plate 513 are on the same plane, and the hinge member has a damping effect to prevent the rapid flipping of the side plates 512 and the top plate 513 caused by the rebound of the elastic rod 520, thereby avoiding damage to the drugs and instruments.

[0064] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 8 and Figure 9 shown, rod sleeves 521 are respectively arranged on the bottom plate 511, the side plates 512, and the top plate 513, and the elastic rod 520 sequentially passes through a plurality of rod sleeves 521.

[0065] As a possible situation, the flat carrying frame 510 is an integral flexible plate rather than a segmented plate body. The outer wall of the flexible plate is coated with a textile fabric. The rod sleeves 521 are arranged at intervals inside the flat carrying frame 510, and the elastic rod 520 sequentially passes through a plurality of rod sleeves 521 to form a bag-like structure of the first aid kit. When being stored, medical staff bend the two ends of the flat carrying frame 510 upward and move them closer to the center of the flat carrying frame 510, so that the covering end of the covering and blocking device 600 abuts against the center of the top of the flat carrying frame 510.

[0066] In an embodiment of the present application, as Figures 8 to 10 shown, the covering and blocking device 600 includes a blocking plate 610, a flat pushing structure 620, and a connecting rod structure 630.

[0067] Among them, the blocking plate 610 is rotatably arranged on the flat carrying frame 510, and the top of the blocking plate 610 abuts against the center of the top of the flat carrying frame 510. The flat pushing structure 620 is arranged at the bottom of the flat carrying frame 510, and the bottom of the blocking plate 610 is connected to the flat pushing structure 620, so as to push or pull the pushing end of the flat pushing structure 620 through the rotation of the blocking plate 610. The connecting rod structure 630 is arranged at the center of the bottom of the flat carrying frame 510, and the two linkage ends of the connecting rod structure 630 are respectively pivotally connected to the pushing ends of the two flat pushing structures 620, so that the two blocking plates 610 rotate symmetrically.

[0068] It should be noted that when one of the blocking plates 610 rotates, the bottom of the blocking plate 610 pushes the moving end of the flat pushing structure 620 to move horizontally. Thus, through the linkage of the connecting rod structure 630, the flat pushing structure 620 at the other blocking plate 610 is driven to move in the opposite direction, thereby realizing the reverse rotation of the other blocking plate 610, and further realizing the rotation of the two blocking plates 610 towards each other or away from each other.

[0069] As a possible scenario, the blocking plate 610 extends to the left and right sides to block the front and rear openings that appear when the flat carrier 510 is folded and stored, effectively preventing the medicines and instruments in the emergency module compartment 500 from falling out after falling off from the fixing member 700.

[0070] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 9 As shown, the horizontal push structure 620 includes a push rod 621 , a sliding block 622 , a fixing bar 623 and a connecting plate 624 .

[0071] Among them, the push rod 621 is pivotally connected to the bottom of the blocking plate 610, the slider 622 is rotatably set at the rod end of the push rod 621, the fixing bar 623 is set at the bottom of the flat carrier frame 510 along the front-to-back direction, and the slider 622 is slidably embedded in the fixing bar 623, and the connecting plate 624 is set on the slider 622 and is pivotally connected to the connecting end of the connecting rod structure 630.

[0072] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 10 and Figure 12 As shown, the connecting rod structure 630 includes a central rod 631 , a second torsion spring 632 and a connecting rod 633 .

[0073] Among them, the center rod 631 can be rotatably set at the bottom center of the flat carrier 510, and the two rod ends of the center rod 631 are pivotally connected to the connecting plate 624 through the hinged connecting rod 633, and the second torsion spring 632 is sleeved on the rotation axis of the center rod 631 to reset the center rod 631.

[0074] Specifically, when the box cover 200 is closed, the abutment block 201 presses the blocking plate 610 at the front end, and the blocking plate 610 at the front end remains in a pressed state, abutting against the front end at the top center of the flat carrier 510, and the blocking plate 610 at the rear end synchronously abuts against the rear end at the top center of the flat carrier 510 through the connecting rod structure 630. The two blocking plates 610 jointly suppress the release of the elastic force of the elastic rod 520, so that the flat carrier 510 cannot be unfolded. At this time, the second torsion spring 632 is in a torsion storage state. Due to the reset effect of the second torsion spring 632, the connecting rod structure 630 always maintains the state of pulling the moving end of the push structure 620.

[0075] When the handle switch 300 is pressed to open the box cover 200, the abutting block 201 disengages from the front baffle 610, and the elastic rod 520 pushes the flat carrying frame 510 due to the reset action. The flat carrying frame 510 pushes the baffle 610 in the opposite direction, causing the baffle 610 to rotate outward. Moreover, the bottom of the baffle 610 pushes the push rod 621, and the push rod 621 drives the slider 622 to slide along the fixed bar 623. Then, the connecting plate 624 moves along with the slider 622. Combining with the reset action of the second torsion spring 632, the link structure 630 enhances the effect of pulling and pushing the flat pushing structure 620, and the moving ends of the two flat pushing structures 620 approach each other, realizing the outward rotation of the two baffles 610.

[0076] As a possible situation, as Figure 1 shown, a detachable U-shaped pin 601 is provided on the covering end of the covering and blocking device 600. After the two ends of the U-shaped pin 601 pass through the covering end of the covering and blocking device 600, they respectively penetrate through both sides of the center of the top of the flat carrying frame 510.

[0077] It should be noted that when the first aid module bin 500 is not installed on the box body 100, the elastic release of the elastic rod 520 can be restricted by inserting the U-shaped pin 601 to avoid the situation where the flat carrying frame 510 unfolds.

[0078] In addition, when the first aid module bin 500 is not installed on the box body 100, relevant medical staff can choose whether to pull out the U-shaped pin 601. If the U-shaped pin 601 is pulled out, when the handle switch 300 is pressed, the flat carrying frame 510 can unfold synchronously with the display rack 410. If the U-shaped pin 601 is not pulled out, when the handle switch 300 is pressed, only the display rack 410 can be unfolded. When the drugs and instruments in the first aid module bin 500 need to be used subsequently, the relevant medical staff can pull out the U-shaped pin 601, and then the flat carrying frame 510 unfolds under the action of the elastic rod 520.

[0079] In an embodiment of the present application, as Figure 4 and Figure 11 shown, a sliding groove 102 is opened at the top of the box body 100, a limiting groove 103 is opened on the sliding groove 102, a sliding rail 501 is provided at the bottom of the flat carrying frame 510, the sliding rail 501 is slidably arranged in the sliding groove 102, and an installation groove 502 is opened on the sliding rail 501. A limiting head 503 that slides along the notch is arranged in the installation groove 502. The limiting head 503 is connected to the installation groove 502 through a compression spring 504. The limiting head 503 matches the limiting groove 103, and the sliding groove 102 is a T-shaped groove.

[0080] It should be noted that the slide rail 501 resists sliding in the slide groove 102 to prevent the slide rail 501 from slipping. For example, flexible ribs are embedded on both sides of the slide groove 102. When the slide rail 501 slides, the flexible ribs are squeezed and deformed, so that the slide rail 501 has a certain resistance to be pushed into the slide groove 102.

[0081] When the medical staff installs the emergency module warehouse 500 into the box body 100, they align the T-shaped slide rail 501 at the bottom of the flat carrier frame 510 with the slide groove 102 at the top of the box body 100 and push it horizontally. During the translation of the slide rail 501 along the slide groove 102, the T-shaped cross-sectional structure of the slide groove 102 constrains the slide rail 501 to slide only in the horizontal direction, thereby eliminating the left and right deviation and up and down shaking of the emergency module warehouse 500.

[0082] When the slide rail 501 moves to the preset position, the limit head 503 in the installation groove 502 extends outward under the continuous pushing of the extrusion spring 504, and is embedded in the limit groove 103 on the slide groove 102. The limit head 503 matches the limit groove 103 to achieve a limiting effect. In addition, the limit head 503 and the limit groove 103 can enhance the limiting effect through magnetic attraction.

[0083] When it is necessary to disassemble the first aid module bin 500, the medical staff pushes the first aid module bin 500 in the reverse direction. At this time, the limit head 503 squeezes the extrusion spring 504 into the installation groove 502, so that the limit head 503 is disengaged from the limit groove 103. The medical staff continues to push the first aid module bin 500 in the reverse direction to separate the first aid module bin 500 from the box body 100.

[0084] In one embodiment of the present application, when the size of the box is small, such as Figure 1 As shown, in order to further improve the portability of the present application, a lifting strap 104 is provided on the side of the box 100 , and medical personnel can lift and carry the present application through the lifting strap 104 .

[0085] In another embodiment of the present application, when the box 100 is larger in size, such as Figure 15 As shown, universal wheels 800 are provided at the four corners of the bottom of the box 100, and the universal wheels 800 are provided with brake structures, and medical staff can limit the movement of the universal wheels 800 by stepping on the brake structures.

[0086] It should be noted that when the universal wheel 800 is provided at the bottom of the box body 100, the hinge between the box cover 200 and the box body 100 is a limit hinge. Specifically, the box cover 200 is opened and rotated to be flush with the bottom of the box body and then limited, so that after the display rack 410 is pushed out by the outward push structure 420, it can support the display rack 410 to prevent the display rack 410 from slipping.

[0087] In addition, a pulling structure 900 is provided at the rear end of the box body 100 for dragging the entire device to move. The pulling structure 900 includes a telescopic rod 910, a pulling rod 920, and a card slot 930. Among them, the telescopic rod 910 is rotatably arranged on the rear end of the box body 100, the pulling rod 920 is arranged at the telescopic end of the telescopic rod 910, and a card slot 930 is arranged on the outer wall of the rear end of the box body 100. When the telescopic rod 910 is retracted to be close to the box body 100, the telescopic rod 910 is clamped in the card slot 930.

[0088] It should be noted that when different medical staff pull the box body 100, the telescopic length of the telescopic rod 910 can be adjusted according to the height of the medical staff. When the pulling structure 900 is not in use, the telescopic rod 910 is retracted and rotated to be close to the box body 100, and then the outer wall of the telescopic rod 910 is clamped in the bayonet of the card slot 930. This can not only achieve a stable storage effect, but also effectively reduce the physical interference with the cover blocking device 600 through the retraction of the telescopic rod 910.

[0089] In summary, for the quick-detachable hierarchical modular first aid kit according to the embodiment of the present application, by placing conventional instruments and medicines on the outward-pushing and unfolding device 400 and placing targeted instruments and medicines in the first aid module bin 500, medical staff can select a suitable first aid module bin 500 according to the type of first aid and quickly install it on the box body 100. This can not only classify instruments and medicines and reduce the risk of mis-taking, but also adapt to different first aid scenarios. During first aid, medical staff only need to press the handle switch 300, and the box cover 200 will open, then the outward-pushing and unfolding device 400 can be pushed out and unfolded. The flat carrying rack 510 of the first aid module bin 500 is unfolded through the elastic rod 520, realizing a double-layer stepped unfolding action. This is not only convenient for opening and operating, but also provides a more sufficient taking space after unfolding, facilitating medical staff to take items and improving the rescue efficiency.
