Description

Technical Field

[0001] This invention relates to the field of first aid kit technology, specifically a multifunctional pre-hospital first aid kit. Background Technology

[0002] Pre-hospital emergency kits are specialized portable equipment carried and stored by emergency personnel before arriving at the hospital, containing emergency medications, instruments, and medical equipment. They are widely used in emergency situations such as traffic accidents and traumatic bleeding. Their core function is to provide immediate material support for critical procedures such as rapid hemostasis and intravenous infusion, maintaining the patient's vital signs and buying time for subsequent transport and treatment. However, traditional pre-hospital emergency kits often have a single cavity or simple layered structure, lacking independent storage space. Items such as femoral artery tourniquets, sterile gauze, emergency medications, and medical equipment are easily piled together. This not only leads to damage to medications due to compression and impact and affects the sterility of instruments, but also makes it difficult for emergency personnel to quickly locate target items in emergency situations, requiring them to search and sift through the materials, thus prolonging procedures such as femoral artery hemostasis and intravenous puncture. Preparation time for critical operations may delay patient treatment; at the same time, some multi-layered first aid kits require opening all shelves to retrieve specific items, which can easily lead to the exposure and contamination of unused supplies, further affecting emergency safety; on the other hand, most emergency medications need to be stored at a constant temperature of around 20°C, while ordinary kits rely solely on their own insulation materials, and the internal temperature can easily exceed the standard in high-temperature environments, causing medications to deteriorate and become ineffective, directly affecting the treatment outcome; in addition, for patients requiring intravenous infusion, additional medical staff or family members need to be arranged to hold the infusion bag, which wastes limited emergency manpower and may also cause instability and shaking due to the holding height, leading to poor infusion and increasing patient discomfort and treatment risks. Therefore, those skilled in the art have provided a multi-functional pre-hospital first aid kit to solve the problems mentioned in the background art. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional pre-hospital emergency kit to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A multifunctional pre-hospital emergency kit includes a base plate and a support structure. A back plate is fixedly connected to one side of the top of the base plate, a top plate is fixedly connected to the top of the back plate, and a central shaft is fixedly connected to one side of the top of the top plate. The bottom of the central shaft passes through the top of the top plate and extends into the interior of the base plate. A support structure is slidably connected inside the central shaft.

[0006] As a further embodiment of the present invention: the support structure includes an infusion rod, a connecting plate, connecting ropes, hooks and a first protruding button. The connecting plate is fixedly connected to the top of the infusion rod, and three connecting ropes are fixedly connected at equal intervals to the bottom of the connecting plate. Each connecting rope is fixedly connected to a hook on the side away from the connecting plate. The first protruding button is movably connected to both sides of the lower part of the infusion rod arm through a spring.

[0007] As a further embodiment of the present invention: a placement groove adapted to the hook on the bracket structure is provided on one side of the top of the top plate and the outer side of the central shaft; circular grooves corresponding to the first protruding button are provided on both sides of the upper part of the central shaft arm; and the circular grooves are snap-fitted to the first protruding button.

[0008] As a further embodiment of the present invention: two connecting frames are fixedly connected to one side of the back panel, each connecting frame is fixedly connected to a fixed shaft, and each fixed shaft is rotatably connected to a cabinet door, each cabinet door is fixedly connected to a handle.

[0009] As a further embodiment of the present invention: each of the four corners of the bottom of the base plate is fixedly connected with a movable wheel, and the movable wheel is a locking wheel; the base plate and the top plate are fixedly connected to the side of the connecting frame and a shoulder strap is fixedly connected between them.

[0010] As a further embodiment of the present invention: a fixed shelf is fixedly connected to the middle of the central shaft arm, and three and two rotating blocks are fixedly connected at equal intervals on the upper part of the central shaft, the upper part of the fixed shelf, and the lower part of the fixed shelf, respectively. Each rotating block is fixedly connected to a first shelf, a second shelf, a third shelf, a fourth shelf, and a fifth shelf from bottom to top on one side, and a handle is fixedly connected to each shelf.

[0011] As a further embodiment of the present invention: a base is fixedly connected to the bottom of the fixed shelf, and a placement cabinet is slidably connected inside the base. Three storage slots are equidistantly provided inside the placement cabinet, and each storage slot contains a shaped and encapsulated phase change material module. A connecting block is fixedly connected to the middle of one side of the top of the placement cabinet, and a connecting slot is provided on the connecting block.

[0012] As a further embodiment of the present invention: a locking block corresponding to the connecting groove is fixedly connected in the groove in the upper middle part of one side of the base, and the locking block is snapped to the connecting groove. A second protruding button is movably connected to the top of the locking block by a spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In use, firstly, when it is necessary to carry the device to the emergency scene, the appropriate carrying method can be selected according to the road conditions and distance: if the scene is far away and the road conditions are flat, the locking of the moving wheels can be released, and the moving wheels can be used to move the device conveniently by pushing and pulling. After arriving at the scene, the moving wheels can be locked again to ensure that the device is placed stably and to avoid displacement during emergency operations; if encountering complex road conditions such as stairs or narrow passages, or if a rapid transfer is required, the operator can put the double shoulder straps on their shoulders and use the load-bearing design of the shoulder straps to carry the device stably, freeing their hands to carry other emergency equipment and meeting the flexible movement needs of pre-hospital emergency care;

[0015] 2. Upon arrival at the emergency scene, if intravenous support is required, pull the connecting plate upwards. Under the pulling force, the infusion rod, fixedly connected to the connecting plate, will smoothly slide out from the hollow cavity inside the central shaft. During the sliding process, the first protruding buttons on both sides of the lower part of the infusion rod arm will be compressed by the inner wall of the central shaft, compressing the internal spring. When the infusion rod is stretched to the height that meets the clinical infusion requirements, the first protruding buttons will precisely align with the corresponding height groove preset on the upper part of the central shaft arm. At this time, the buttons will automatically pop out and lock into the groove under the elastic restoring force of the spring. A stable snap-locking positioning structure is formed to fix the length of the infusion rod, preventing it from sliding down due to external force or its own weight during infusion, thus ensuring a stable infusion height. During this process, the three connecting ropes fixed at equal intervals at the bottom of the connecting plate will detach from the pre-set placement slots at the top of the top plate as the connecting plate rises, and hang naturally below the connecting plate. Operators can hang the infusion bag or infusion bottle on the three hooks respectively according to the infusion needs, thereby providing reliable protection for infusion and meeting the clinical needs of quickly establishing intravenous access and maintaining infusion in pre-hospital emergency scenarios.

[0016] 3. To access internal medical equipment or medications, grasp the handle on the cabinet door and pull it to both sides. The cabinet door will rotate and open around the fixed axis on the connecting frame, revealing five independent shelves inside. According to the preset storage position of the equipment, pull the handle on the corresponding shelf to rotate the shelf around the rotating block and the central axis, realizing the independent opening and closing of each shelf. There is no need to open all shelves at once, which shortens the time for accessing the target equipment and reduces the contact between other items in the shelves and the external environment, effectively avoiding contamination or disorder. After use, push the handle in the opposite direction to rotate the shelf back to its original position, and close the cabinet door to restore the sealed state.

[0017] 4. For medical supplies requiring constant temperature storage, such as specific emergency medicines and sterile instruments, check the status of the shaped-encapsulated phase change material module inside the storage cabinet before use to ensure it is within the effective temperature control range. If the module fails to control temperature due to long-term use or environmental factors, it must be replaced promptly. First, press the second protruding button on the base to disengage the locking spring from the connecting slot of the connecting block. Then, pull the storage cabinet outward, remove the failed module, and replace it with a new active module. Push the storage cabinet back into the base until the locking block re-engages in the connecting slot to complete the module replacement. The shaped-encapsulated phase change material module, through its solid-liquid phase change characteristics, precisely absorbs or releases heat at around 20°C, thereby creating a stable constant temperature environment for the medicines in the two shelves below the fixed shelf, ensuring stable performance throughout the emergency treatment process. Furthermore, the shaped-encapsulated design of the module completely prevents liquid leakage during the phase change process, ensuring the cleanliness and safety of the medical supplies.

Detailed Implementation

[0025] 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.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This embodiment provides a multifunctional pre-hospital emergency kit, including a base plate 1 and a support structure 5. A back plate 17 is fixedly connected to one side of the top of the base plate 1, and a top plate 4 is fixedly connected to the top of the back plate 17. A central shaft 12 is fixedly connected to one side of the top of the top plate 4, and the bottom of the central shaft 12 passes through the top of the top plate 4 and extends into the interior of the base plate 1. The support structure 5 is slidably connected inside the central shaft 12. A placement groove 11 adapted to the hook 54 on the support structure 5 is opened on one side of the top of the top plate 4 and the outer side of the central shaft 12. Circular grooves corresponding to the first protruding button 55 are opened on both sides of the upper part of the central shaft 12, and the circular grooves are snap-fitted to the first protruding button 55. Two... A connecting frame 8 is fixedly connected to each of its four corners, and each of these fixed shafts is rotatably connected to a cabinet door 3. Each cabinet door 3 has a handle 6 fixedly connected to it. The bottom plate 1 has four fixedly connected casters 2 at its four corners; these casters 2 are locking casters. A carrying strap 7 is fixedly connected between the bottom plate 1 and the top plate 4, which are near the connecting frame 8. When carrying the device to an emergency scene, a suitable carrying method can be selected based on road conditions and distance: if the scene is far and the road is flat, the locking of the casters 2 can be released, allowing for convenient pushing and pulling of the device. Upon arrival at the scene, the casters 2 can be relocked to ensure stable placement of the device and prevent displacement during emergency operations. If encountering stairs, narrow passages, etc., the carrying method can be adjusted accordingly. In complex road conditions or when rapid relocation is required, operators can sling the shoulder straps 7 over their shoulders. The weight-bearing design of the shoulder straps 7 allows for stable carrying of the device, freeing their hands to carry other emergency equipment and meeting the flexible mobility needs of pre-hospital emergency care. A fixed shelf 9 is fixedly connected to the middle of the central axis 12 arm. Three and two rotating blocks 18 are equidistantly fixed to the upper and lower parts of the central axis 12 and the fixed shelf 9, respectively. Each rotating block 18 has a first shelf 19, a second shelf 20, a third shelf 21, a fourth shelf 22, and a fifth shelf 23 fixedly connected to one side from bottom to top. Each shelf has a handle 24 fixedly connected to it. According to the preset storage position of the equipment, pulling the handle 24 on the corresponding shelf will move the device. The movable shelf rotates around the rotating block 18 and the central axis 12, realizing the independent opening and closing of a single shelf without having to open all shelves at once. This shortens the time for retrieving the target equipment and reduces the contact between items in other shelves and the external environment, effectively avoiding contamination or chaos. After use, push the pull handle 24 in the opposite direction to rotate the shelf back to its original position, and close the cabinet door 3 to restore the sealed state. The bottom of the fixed shelf 9 is fixedly connected to the base 10, and the base 10 is slidably connected to the placement cabinet 13. The placement cabinet 13 has three equidistant slots, and each slot contains a shaped and encapsulated phase change material module. A connecting block 14 is fixedly connected to the middle of one side of the top of the placement cabinet 13, and the connecting block 14 has a connecting groove.A locking block 15, corresponding to the connecting slot, is fixedly connected to a groove in the upper middle part of one side of the base 10. The locking block 15 is snapped into the connecting slot. A second protruding button 16 is movably connected to the top of the locking block 15 via a spring. For medical supplies requiring constant temperature storage, such as specific emergency medicines and sterile instruments, the status of the shaped and encapsulated phase change material module in the storage cabinet 13 must be checked before use to confirm that it is within the effective temperature control range. If the module fails to control the temperature due to long-term use or environmental influences, it must be replaced in time. First, press the second protruding button 16 on the base 10 to release the locking block 15 from the connecting block by compressing the spring. The connecting slot of 14 is then pulled out, and the placement cabinet 13 is removed. The failed module is taken out and replaced with a new active module. The placement cabinet 13 is then pushed back into the base 10 until the locking block 15 re-engages in the connecting slot, completing the module replacement. The shaped and encapsulated phase change material module, through its own solid-liquid phase change characteristics, precisely absorbs or releases heat at around 20°C, thereby creating a stable constant temperature environment for the medicines in the two shelves below the fixed shelf 9, ensuring their stable performance throughout the entire emergency treatment process. Furthermore, the shaped and encapsulated design of the module completely avoids liquid leakage during the phase change process, ensuring the cleanliness and safety of medical supplies.

[0028] Example 2

[0029] Reference Figure 1-6This embodiment is based on the previous embodiment, but differs in that the support structure 5 includes an infusion rod 51, a connecting plate 52, connecting ropes 53, hooks 54, and first raised buttons 55. The top of the infusion rod 51 is fixedly connected to the connecting plate 52, and three connecting ropes 53 are fixedly connected at equal intervals to the bottom of the connecting plate 52. Each connecting rope 53 has a hook 54 fixedly connected to the side away from the connecting plate 52. The lower sides of the infusion rod 51 are movably connected to the first raised buttons 55 by springs. After arriving at the emergency scene, if infusion support is needed, the connecting plate 52 can be pulled upwards directly. Under the pulling force, the infusion rod 51 fixedly connected to the connecting plate 52 will slide smoothly out of the hollow cavity inside the central shaft 12. During the sliding process, the first raised buttons 55 on both sides of the lower sides of the infusion rod 51 will be compressed by the inner wall of the central shaft 12, thus compressing the internal springs. When the infusion rod 51 is stretched to the height required for clinical infusion, the first protruding button 55 will precisely align with the corresponding height groove on the upper part of the central axis 12 arm. At this time, the button will automatically pop out and lock into the groove under the elastic restoring force of the spring, forming a stable snap-locking positioning structure. This will fix the length of the infusion rod 51 and prevent it from sliding down due to external force or its own weight during infusion, ensuring a stable infusion height. During this process, the three connecting ropes 53 fixed at equal intervals at the bottom of the connecting plate 52 will detach from the preset placement groove 11 at the top of the top plate 4 as the connecting plate 52 rises, and hang naturally below the connecting plate 52. The operator can hang the infusion bag or infusion bottle on the three hooks 54 according to the infusion needs, thereby providing reliable protection for infusion and meeting the clinical needs of quickly establishing intravenous access and maintaining infusion in pre-hospital emergency scenarios.
