Description

Technical Field

[0001] The present invention relates to the technical field of first aid kits, and more particularly to a multifunctional waterproof first aid kit. Background Art

[0002] A first aid kit is a small bag containing first aid medicines, sterilized gauze, bandages, etc. It is a rescue item used in emergencies when people encounter accidents. It can be divided into different categories according to different environments and different users. For example, it can be divided into household first aid kits, outdoor first aid kits, car first aid kits, gift first aid kits, earthquake first aid kits, etc. according to different users.

[0003] However, first-aid kits in the prior art only have the function of storing first-aid items. When encountering rain outdoors, since the first-aid kits usually contain a variety of medicines, such as disinfectants, hemostatics, etc., these medicines may deteriorate after coming into contact with water, thereby losing their original efficacy. For example, disinfectants such as iodine tincture and alcohol may be diluted after coming into contact with water, resulting in a weakening of the disinfection effect. The instruments in the first-aid kit, such as scissors and tweezers, may rust or be damaged after coming into contact with water, thereby affecting their normal use. Moreover, water may contain a variety of impurities and bacteria. If the first-aid kit is exposed to rainwater, the items inside it may be contaminated by the rainwater, thereby increasing the risk of infection during use. In a rainy environment, the first-aid kit may become heavy due to being wet by rainwater, making it difficult to open and use quickly. At the same time, slippery packaging may also cause the hands to slip during use, reducing the accuracy of operation.

[0004] For example, the Chinese patent application number 201910405476.6 discloses a waterproof first aid kit, comprising: a box body, a cover body, a first airbag, a second airbag, and an airbag inflation assembly. After the first airbag is inflated, it expands toward the cover body and seals against the surface of the cover body facing the box body. The second airbag is arranged around the first airbag. After the second airbag is inflated, it expands radially outward along the accommodating cavity to lift the side wall of the box body to increase the buoyancy of the box body. By providing the first airbag and the second airbag, not only can the first airbag and the cover body cooperate to seal the gap between the cover body and the box body to prevent water from entering the accommodating cavity and contaminating the medicine, but the second airbag can also increase the volume of the box body after inflation, thereby improving the floating performance of the waterproof first aid kit and preventing the waterproof first aid kit from sinking when wading.

[0005] However, although the first aid kit can provide preliminary waterproofing against rain and other factors, in extreme situations, such as prolonged contact with water, water may gradually seep into the first aid kit. The first aid kit lacks further protective structure for first aid supplies, which can easily cause damage to the first aid items.

[0006] Therefore, the present invention proposes a multifunctional waterproof first aid kit to solve the above problems. Summary of the Invention

[0057] See also Figure 3 、 Figure 7 and Figure 8As shown, the storage component 104 includes two storage plates 1041 that are opposite to each other and located in the middle of the protective cavity 501. A plurality of storage bags 1042 and fixing belts 1043 are provided at the upper and lower ends of the storage plate 1041. The left end of the upper storage plate 1041 and the right end of the lower storage plate 1041 are connected to the first inner wall layer 101 through an elastic belt 1044. A limit seat 6 is provided at the left and right ends of the first inner wall layer 101. The cross-section of the limit seat 6 is C-shaped. The free end of the storage plate 1041 is provided with a limit block 7 that cooperates with the limit block 7. When the limit block 7 cooperates with the limit seat 6, the storage plate 1041 is in a horizontal state.

[0058] See also Figure 3 、 Figure 4 and Figure 6 As shown, the upper end of the sealed cavity 401 extends out of the first cavity 103 and is provided with two parallel first sealing strips 403, and two second sealing strips 404 corresponding to the first sealing strips 403 are provided in the second cavity 203. When the upper end of the first sealing strip 403 contacts the lower end of the second sealing strip 404, the first aid kit body 1 and the cover body 2 are in a sealed state.

[0059] See also Figure 11 As shown, a first waterproof zipper 302 is provided between the first inner wall layer 101 and the second inner wall layer 201, and a second waterproof zipper 303 is provided between the first outer wall layer 102 and the second outer wall layer 202. The movable parts of the first waterproof zipper 302 and the second waterproof zipper 303 are both provided with strong magnetic blocks 8. The two strong magnetic blocks 8 attract each other and are used to keep the movable parts of the first waterproof zipper 302 and the second waterproof zipper 303 moving synchronously.

[0060] See also Figure 5 As shown, the inflation and deflation component 402 includes a shell 4021 located on the rear side of the first aid kit body 1, and an air pump 4022, a power supply 4023 and a control module 4024 are provided in the shell 4021. The air pump 4022, the power supply 4023 and the control module 4024 are electrically connected. The power supply 4023 is used to power the air pump 4022, and the control module 4024 is used to control the air pump 4022 to inflate or deflate. A first air pipe 4025 is provided at the left end of the air pump 4022, and the free end of the first air pipe 4025 passes through the first inner wall layer 101 and is connected to the sealed cavity 401.

[0061] It should be noted that the air pump 4022, power supply 4023 and control module 4024 in the housing 4021 are all existing technologies and will not be described in detail here.

[0062] During use, in the initial state, the first and second waterproof zippers 302 and 303 are both tightened, and the two first sealing strips 403 at the upper end of the sealed cavity 401 are in contact with the second sealing strips 404 on the corresponding sides. When the user needs to place first aid items into the first aid kit body 1, they first need to use the control module 4024 to control the air pump 4022 to evacuate air, causing the air in the sealed cavity 401 to be drawn in by negative pressure, initially entering the air pump 4022 through the first air pipe 4025, and then flowing to the outside air through the outlet of the air pump 4022. The sealed cavity 401 gradually changes from an inflated state to a deflated state, and the two first sealing strips 403 at the upper end of the sealed cavity 401 separate from the corresponding second sealing strips 404, and the upper end of the sealed cavity 401 leaves the second cavity 203. Of course, to reduce the cost and weight of the first aid kit, a manual air pump can also be used to complete the above preparations.

[0063] When the sealed cavity 401 is completely deflated, the air pump 4022 is turned off, and the user can pull the movable part of the second waterproof zipper 303. The movable part of the second waterproof zipper 303 drives the movable part of the first waterproof zipper 302 to move synchronously through the two strong magnetic blocks 8 until the first waterproof zipper 302 and the second waterproof zipper 303 are evenly divided into two upper and lower parts. At this time, the first inner wall layer 101 is separated from the second inner wall layer 201, and the first outer wall layer 102 is separated from the second outer wall layer 202, that is, the cover body 2 is separated from the first-aid kit main body 1. The user can open the cover body 2 upwards. A connecting belt 301 is provided between the cover body 2 and the first-aid kit main body 1, which can make the cover body 2 and the first-aid kit main body 1 always as a whole, avoiding the cover body 2 and the first-aid kit main body 1 being completely separated and lost.

[0064] After opening the cover 2, the opening at the upper end of the first aid kit main body 1 is exposed, and the user can first squeeze the upper storage plate 1041 to the left, and the upper storage plate 1041 squeezes the elastic band 1044 between the first inner wall layer 101, and the limit block 7 at the right end of the upper storage plate 1041 is separated from the limit seat 6. At this time, the upper storage plate 1041 can swing freely upward, and at the same time, the lower storage plate 1041 is exposed, and the user can squeeze the lower storage plate 1041 to the right, and the lower storage plate 1041 squeezes the elastic band 1044 between the first inner wall layer 101, and the limit block 7 at the left end of the lower storage plate 1041 is separated from the limit seat 6. At this time, the lower storage plate 1041 can swing freely upward.

[0065] The user can swing both storage plates 1041 upward and extend them out of the opening at the upper end of the first aid kit body 1, and then place first aid items such as bottles that need anti-collision protection in the storage bag 1042, and fix the first aid tools and other first aid items with the fixing belt 1043. After the first aid items are placed, the user can swing the two storage plates 1041 downward from bottom to top in sequence, and clamp the limit blocks 7 at the free ends of the storage plates 1041 in the corresponding limit seats 6. At this time, the two storage plates 1041 cannot swing freely and are both in a horizontal state.

[0066] The user puts the cover 2 back on the first-aid kit main body 1, and then pulls the movable part of the second waterproof zipper 303. The movable part of the second waterproof zipper 303 drives the movable part of the first waterproof zipper 302 to move synchronously through the two strong magnetic blocks 8 until the first waterproof zipper 302 and the second waterproof zipper 303 are both tightened. At this time, the first inner wall layer 101 and the second inner wall layer 201 are reconnected together, and the first outer wall layer 102 and the second outer wall layer 202 are reconnected together, that is, the cover 2 is fixed on the first-aid kit main body 1 by the first waterproof zipper 302 and the second waterproof zipper 303.

[0067] The user activates the air pump 4022 via the control module 4024 to inflate the air. The air pump 4022 continuously draws in external air and injects the air into the sealed cavity 401 through the first air pipe 4025. The sealed cavity 401 gradually expands, and the upper end of the sealed cavity 401 gradually enters the second cavity 203. The two first sealing strips 403 at the upper end of the sealed cavity 401 gradually contact the corresponding second sealing strips 404, completing the sealing of the connection between the cover 2 and the first aid kit body 1. Of course, to reduce the cost and weight of the first aid kit, a manual inflator can also be used to complete the above preparations.

[0068] When there is water outside the first-aid kit main body 1 and the cover 2, since the first-aid kit main body 1 and the cover 2 are both made of waterproof materials, water cannot pass through the first-aid kit main body 1 and the cover 2, and can only enter the interior from the connection between the first-aid kit main body 1 and the cover 2. The second waterproof zipper 303 plays a primary waterproof role, the first sealing strip 403 and the second sealing strip 404 play a secondary waterproof role, and the first waterproof zipper 302 plays a tertiary waterproof role. Through the multi-layer waterproof structure, it can effectively prevent water from entering the first-aid kit main body 1 and contaminating first-aid items.

[0069] Example 2

[0070] During actual use, it was found that in some extreme cases, such as heavy rain or flooding, when the first aid kit is exposed to water for too long, water may penetrate into the first aid kit through the gap between the first sealing strip 403 and the second sealing strip 404, and the user cannot handle the first aid supplies. The existing first aid kit lacks further protection for the first aid items, thereby contaminating the first aid items and affecting their use. Further improvements are made on the basis of the above embodiments.

[0071] See also Figure 3 As shown, the multifunctional waterproof first aid kit of the present invention also includes a protective part 5, which includes a protective cavity 501 arranged at the left end of the first inner wall layer 101. An automatic inflation component 502 is provided on the upper side of the first aid kit body 1. When the automatic inflation component 502 comes into contact with water, the protective cavity 501 is automatically inflated.

[0072] See also Figure 3 、 Figure 4 、 Figure 9 and Figure 10 As shown, the cross section of the protective cavity 501 is in the shape of a square. The right end of the protective cavity 501 can contact the right end of the first inner wall layer 101. The storage component 104 is located in the middle of the protective cavity 501. The automatic inflation component 502 includes a reaction shell 5021 located on the upper side of the first aid kit body 1. The reaction shell 5021 is detachably connected to the first inner wall layer 101. The upper end of the reaction shell 5021 is provided with a plurality of through holes 5022 evenly distributed along its length. The lower end of the reaction shell 5021 is detachable. The detachable connector is provided with a second air pipe 5023, the free end of which is provided with a one-way valve 5024 with an opening away from the reaction shell 5021. A connecting pipe 5025 is provided on the protective cavity 501, and the free end of the connecting pipe 5025 is connected to the one-way valve 5024. A water-permeable membrane is provided on the upper part of the reaction shell 5021, and aluminum carbonate 5026 is provided in the water-permeable membrane. When the aluminum carbonate 5026 comes into contact with water, a chemical reaction will occur and gas will be released, automatically inflating the protective cavity 501.

[0073] It should be noted that aluminum carbonate 5026 is in powder form at room temperature. The water-permeable membrane mainly plays a role in shaping aluminum carbonate 5026. Aluminum carbonate 5026 is a disposable item and needs to be replaced after one use.

[0074] See also Figure 4 As shown, two symmetrically distributed arc plates 9 are provided in the reaction shell 5021 , and the arc plates 9 are used to isolate the water-permeable membrane and aluminum carbonate 5026 at the upper part of the reaction shell 5021 .

[0075] See also Figure 9 and Figure 11As shown, a Velcro tape 10 is provided on the outside of the reaction shell 5021 , and a Velcro tape 11 that can be bonded to the Velcro tape 10 is provided on the first inner wall layer 101 .

[0076] On the basis of the above embodiment, during use, when water breaks through the seal of the sealing portion 4 and enters the first aid kit body 1, the water will flow to the reaction shell 5021 as soon as it enters the first aid kit body 1, enter the interior of the reaction shell 5021 through the multiple through holes 5022 on the reaction shell 5021, and finally pass through the water-permeable membrane and contact with the aluminum carbonate 5026. The water and the aluminum carbonate 5026 react chemically to produce carbon dioxide gas. The carbon dioxide gas passes through the gap between the two arc plates 9 and flows into the second air pipe 5023 below the reaction shell 5021, and then passes through the one-way valve 5024 and the connecting pipe 5025 to enter the protective cavity 501. Since the opening of the one-way valve 5024 is far away from the reaction shell 5021, the gas in the protective cavity 501 cannot pass through the one-way valve 5024.

[0077] The protective cavity 501 gradually expands, and the right end of the protective cavity 501 begins to move to the right. Since the cross-section of the protective cavity 501 is in the shape of a U, the storage component 104 gradually locates in the middle of the protective cavity 501. When the right end of the protective cavity 501 contacts the first inner wall layer 101, the protective cavity 501 and the first inner wall layer 101 form a closed space. The first aid items are located in the closed space. The closed space can prevent water from contaminating the first aid items, and provide an extra layer of waterproof protection for the first aid items, so that they can be used in extreme environments, thereby expanding the scope of application of the first aid kit.

[0078] Since aluminum carbonate 5026 is a disposable item, after the aluminum carbonate 5026 in the reaction shell 5021 undergoes a chemical reaction, the user can open the cover body 2, and then open the Velcro 10 and Velcro 11 bonded together, thereby removing the reaction shell 5021 from the upper side of the first inner wall layer 101, and pulling out the second air pipe 5023 from the bottom of the reaction shell 5021, and then fixing the reaction shell 5021 filled with new aluminum carbonate 5026 on the upper side of the first inner wall layer 101, and then pulling out the one-way valve 5024 from the connecting pipe 5025, and after discharging the gas in the protective cavity 501, reconnect the one-way valve 5024 to the connecting pipe 5025, and reinsert the second air pipe 5023 under the new reaction shell 5021, thereby realizing the reuse of the first aid kit.

[0079] Example 3

[0080] During actual use, it was found that when the right end of the protective cavity 501 moves to the right, due to the lack of a guiding component, the right end of the protective cavity 501 will come into contact with the first aid items when moving to the right. When encountering first aid items that are not firmly fixed, the first aid items may be taken out of the storage bag 1042 or the fixing belt 1043, thereby affecting the protection of the first aid items. Further improvements are made on the basis of the above embodiment.

[0081] See also Figure 9 and Figure 11 As shown, two symmetrically distributed guide rods 12 are provided on the front and rear sides of the first aid kit body 1, the storage component 104 is located between the guide rods 12 on the front and rear sides, and the right end of the protective cavity 501 is provided with multiple guide rings 13 corresponding to the guide rods 12 one by one, and each guide ring 13 is sleeved on the corresponding guide rod 12.

[0082] Based on the above embodiment, during use, when the protective cavity 501 gradually expands, the right end of the protective cavity 501 moves to the right, and the protective cavity 501 drives the multiple guide rings 13 at the right end to move to the right. The multiple guide rings 13 move to the right along the guide rod 12. The multiple guide rods 12 and the guide rings 13 can open the end of the protective cavity 501, so that the end of the protective cavity 501 moves in the horizontal direction, so that the storage component 104 can smoothly enter the middle of the protective cavity 501, and can prevent the protective cavity 501 from hitting the first aid items in the storage component 104, thereby achieving better protection effect.

[0083] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
